coverage beginning on or before September 30, 2021. A  
premium payee was entitled to the COBRA premium  
assistance credit at the time an eligible individual elected  
coverage. Therefore, due to the COBRA notice and election  
period requirements (generally, employers had 60 days to  
provide notice and assistance eligible individuals had 60  
days to elect coverage), the first quarter of 2022 was the last  
quarter in which most employers may have been eligible to  
claim the COBRA premium assistance credit.

Reminders  
The COVID-19 related credit for qualified sick and family  
leave compensation is limited to leave taken after March  
31, 2020, and before October 1, 2021. Generally, the  
credit for qualified sick and family leave compensation, as  
enacted under the Families First Coronavirus Response Act  
(FFCRA) and amended and extended by the COVID-related  
Tax Relief Act of 2020, for leave taken after March 31, 2020,  
and before April 1, 2021, and the credit for qualified sick and  
family leave compensation under sections 3131, 3132, and  
3133 of the Internal Revenue Code, as enacted under the  
ARP, for leave taken after March 31, 2021, and before  
October 1, 2021, have expired. However, employers that pay  
qualified sick and family leave compensation in 2023 for  
leave taken after March 31, 2020, and before October 1,  
2021, are eligible to claim a credit on Form CT-1 filed for  
2023. For more information, see the instructions for line 16,  
line 17b, line 23, and line 24b, later.

Future Developments  
For the latest information about developments related to  
Form CT-1 and its instructions, such as legislation enacted  
after they were published, go to IRS.gov/CT1.  
What's New  
Changes to tax rates and compensation bases. For the  
2023 tax rates and compensation bases, see Employer and  
Employee Taxes, later.  
Outsourcing payroll duties. Generally, as an employer,  
you’re responsible to ensure that tax returns are filed and  
deposits and payments are made, even if you contract with a  
third party to perform these acts. You remain responsible if  
the third party fails to perform any required action. Before you  
choose to outsource any of your payroll and related tax duties  
(that is, withholding, reporting, and paying over income taxes  
and taxes imposed by the Railroad Retirement Tax Act) to a  
third-party payer, such as a payroll service provider or  
reporting agent, go to IRS.gov/OutsourcingPayrollDuties for  
helpful information on this topic. For more information on the  
different types of third-party payer arrangements, see section  
16 of Pub. 15.  
Credit for COBRA premium assistance payments. The  
COBRA premium assistance credit lines have been  
"Reserved for future use" on Form CT-1 because the first  
quarter of 2022 was the last quarter in which most employers  
may have been eligible to claim the COBRA premium  
assistance credit.  
Section 9501 of the American Rescue Plan Act of 2021  
(the ARP) provided for COBRA premium assistance in the  
form of a full reduction in the premium otherwise payable by  
certain individuals and their families who elected COBRA  
continuation coverage due to a loss of coverage as the result  
of a reduction in hours or an involuntary termination of  
employment (assistance eligible individuals). This COBRA  
premium assistance was available for periods of coverage  
beginning on or after April 1, 2021, through periods of  
Correcting a previously filed Form CT-1. If you discover  
an error on a previously filed Form CT-1, make the correction  
using Form CT-1 X. Form CT-1 X is filed separately from

Form CT-1 X or go to IRS.gov/CorrectingEmploymentTaxes.  
Change of address. Use Form 8822-B to notify the IRS of  
General Instructions  
an address change.  
Federal tax deposits must be made by electronic funds  
transfer (EFT). You must use EFT to make all federal tax  
deposits. Generally, an EFT is made using the Electronic  
Federal Tax Payment System (EFTPS). If you don't want to  
use EFTPS, you can arrange for your tax professional,  
financial institution, payroll service, or other trusted third party  
to make electronic deposits on your behalf. Also, you may  
arrange for your financial institution to initiate a same-day  
wire payment on your behalf. EFTPS is a free service  
provided by the Department of the Treasury. Services  
provided by your tax professional, financial institution, payroll  
service, or other third party may have a fee.  
To get more information about EFTPS or to enroll in  
EFTPS, go to EFTPS.gov or call 800-555-4477. To contact  
EFTPS using TRS for people who are deaf, hard of hearing,  
or have a speech disability, dial 711 and then provide the  
TRS assistant the 800-555-4477 number above or  
800-733-4829. Additional information about EFTPS is also  
available in Pub. 966.  
Purpose of Form CT-1  
These instructions give you some background information  
about Form CT-1. They tell you who must file Form CT-1, how  
to complete it line by line, and when and where to file it.  
Use Form CT-1 to report taxes imposed by the Railroad  
Retirement Tax Act (RRTA). Use Form 941, Employer's  
QUARTERLY Federal Tax Return, or, if applicable, Form 944,  
Employer's ANNUAL Federal Tax Return, to report federal  
income taxes withheld from your employees' wages and  
other compensation.  
In accordance with Notice 2021-24, 2021-18 I.R.B. 1122,  
may have reduced deposits of employment taxes otherwise  
required to be made that are reported on Form 941  
(generally, income tax withholding) in anticipation of claiming  
the credit for qualified sick and family leave compensation  
paid in 2023 for leave taken after March 31, 2020, and before  
October 1, 2021. For more information about qualified sick  
and family leave compensation, see the line 1 instructions,  
later. For more information about this credit, see the line 16  
and line 17b instructions, later. Because this credit is  
reported when the 2023 Form CT-1 is filed in 2024, a  
reduction in deposits of income tax withholding as described  
above may have resulted in the issuance of a balance due  
notice and the imposition of penalties and interest when the  
Form 941 quarterly return was processed.  
Paid preparers. If you use a paid preparer to complete  
Form CT-1, the paid preparer must complete and sign the  
paid preparer's section of Form CT-1.  
Additional information. For more information, see one of  
the resources discussed next.  
Pub. 15 contains information for withholding, depositing,  
reporting, and paying over employment taxes.  
Pub. 15-A contains specialized and detailed employment  
tax information supplementing the basic information provided  
in Pub. 15.  
If you reduced your deposits of employment taxes  
reported on Form 941 in anticipation of the credit for qualified  
sick and family leave compensation paid in 2023 for leave  
taken after March 31, 2020, and before October 1, 2021, and  
this resulted in those amounts being included as a balance  
due in a notice, contact us as soon as possible by either (1)  
writing to the address shown on your notice, or (2) calling the  
telephone number shown on your notice. If you contact us in  
writing, include a copy of your notice and the amount of  
employment tax deposits reported on Form 941 that you  
reduced in anticipation of the credit for qualified sick and  
family leave compensation paid in 2023 for leave taken after  
March 31, 2020, and before October 1, 2021. Whether you  
owe tax, penalties, and interest will depend upon the credits  
properly claimed on Form CT-1.  
Pub. 15-B contains information about the employment tax  
treatment of various types of noncash compensation.  
Pub. 915 contains the federal income tax rules for social  
security benefits and equivalent Tier 1 railroad retirement  
benefits.  
The Railroad Retirement Board (RRB) website at RRB.gov  
contains additional employer reporting information and  
instructions.  
How to get forms and publications. You can download or  
print most of the forms and publications you may need at  
IRS.gov/Forms. Otherwise, you can go to IRS.gov/  
OrderForms to place an order and have forms mailed to you.  
The IRS will process your order as soon as possible. Don't  
resubmit requests you've already sent us. You can get forms

Where can you get telephone help? You can call the IRS  
Business and Specialty Tax Line at 800-829-4933 or  
800-829-4059 (TDD/TTY for persons who are deaf, hard of  
hearing, or have a speech disability) Monday–Friday from  
7:00 a.m. to 7:00 p.m. local time (Alaska and Hawaii follow  
Pacific time) for answers to your questions about completing  
Form CT-1 or tax deposit rules.  
Who Must File  
For purposes of these instructions, all references to  
"sick pay" mean ordinary sick pay, not “qualified sick  
leave compensation.”  
TIP  
File Form CT-1 if you paid one or more employees  
compensation subject to tax under RRTA.  
A payer of sick pay (including a third party) must file Form  
CT-1 if the sick pay is subject to Tier 1 railroad retirement  
taxes. Include sick pay payments on lines 8–11 and, if the  
withholding threshold is met, line 12 of Form CT-1. Follow the  
reporting procedures for sick pay reporting in section 6 of  
Pub. 15-A.  
Photographs of Missing Children  
The IRS is a proud partner with the National Center for  
missing children selected by the Center may appear in  
instructions on pages that would otherwise be blank. You can  
help bring these children home by looking at the photographs  
If a third-party payer of sick pay is also paying qualified  
sick leave compensation on behalf of an employer, the third  
party would be making the payments as an agent of the

employer. The employer is required to do the reporting and  
payment of railroad retirement taxes with respect to the  
qualified sick leave compensation and claim the credit for the  
qualified sick leave compensation unless the employer has  
an agency agreement with the third-party payer that requires  
the third-party payer to do the collecting, reporting, and/or  
paying or depositing railroad retirement taxes on the qualified  
sick leave compensation. If the employer has an agency  
agreement with the third-party payer, the third-party payer  
includes the qualified sick leave compensation on the Form  
CT-1 filed by the third party and claims the sick leave credit  
on behalf of the employer on Form CT-1.  
Timing. Compensation is considered paid when it is actually  
paid or when it is constructively paid. It is constructively paid  
when it is set apart for the employee, or credited to an  
account the employee can control, without any substantial  
limit or condition on how and when the payment is to be  
made.  
Any compensation paid during the current year that was  
earned in a prior year is taxable at the current year's tax  
rates; you must include the compensation with the current  
year's compensation on Form CT-1, lines 1–12, as  
appropriate. An exception applies to nonqualified deferred  
compensation that was subject to Tier 1 and Tier 2 tax in a  
prior year. See the rules for nonqualified deferred  
After you file your first Form CT-1, you must file a return for  
each year, even if you didn’t pay taxable compensation  
during the year, until you file a final return.  
compensation plans in section 5 of Pub. 15-A.  
Exceptions. Compensation doesn't include the following.  
Disregarded entities and qualified subchapter S subsid-  
iaries (QSubs). Eligible single-owner disregarded entities  
and QSubs are treated as separate entities for employment  
tax purposes. Eligible single-member entities that haven’t  
elected to be taxed as corporations must report and pay  
employment taxes on compensation paid to their employees  
using the entities' own names and employer identification  
numbers (EINs). See Regulations sections 1.1361-4(a)(7)  
and 301.7701-2(c)(2)(iv).  
Certain benefits provided to or on behalf of an employee if  
at the time the benefits are provided it is reasonable to  
believe the employee can exclude such benefits from  
income. For information on what benefits are excludable, see  
Pub. 15-B. Examples of this type of benefit include:  
1. Certain employee achievement awards under section  
74(c),  
2. Certain scholarship and fellowship grants under  
section 117,  
Where To File  
3. Certain fringe benefits under section 132, and

instructions are defined in section 3231 and in its regulations.  
Exceptions for sickness or accident disability  
payments. For purposes of employee and employer Tier 1  
taxes, compensation doesn't include sickness or accident  
disability payments made to or on behalf of an employee or  
dependents:  
Compensation  
Compensation means payment in money, meaning currency  
issued by a recognized authority as a medium of exchange,  
for services performed as an employee of one or more  
employers. It includes payment for time lost as an employee.  
A few exceptions are described later under Exceptions.  
Under a workers' compensation law,  
Under section 2(a) of the Railroad Unemployment  
Insurance Act for days of sickness due to an on-the-job injury,  
Group-term life insurance. Include in compensation the  
cost of group-term life insurance over $50,000 you provide to  
an employee. This amount is subject to Tier 1 and Tier 2  
taxes, but not to federal income tax withholding. Include this  
amount on your employee's Form W-2, Wage and Tax  
Statement.  
Under the Railroad Retirement Act, or  
More than 6 months after the calendar month the  
employee last worked.  
For purposes of Tier 2 taxes, compensation doesn't  
include payments made to or on behalf of an employee or  
dependents under a sickness or accident disability plan or a  
medical or hospitalization plan in connection with sickness or  
accident disability.  
Former employees for whom you paid the cost of  
group-term life insurance over $50,000 must pay the  
employee's share of these taxes with their Form 1040, U.S.  
Individual Income Tax Return, or Form 1040-SR, U.S. Tax  
Return for Seniors. You’re not required to collect those taxes.  
For former employees, you must include on Form W-2 the  
part of compensation that consists of the cost of group-term  
life insurance over $50,000. You must also separately report  
on Form W-2 the amount of railroad retirement taxes owed by  
the former employee for coverage provided after separation  
from service. For more information, see section 2 of Pub.  
15-B and the General Instructions for Forms W-2 and W-3.

Tips. Your employee must report cash tips to you by the 10th  
day of the month following the month the tips are received.  
The report should include charged tips you paid over to the  
employee for charge customers, tips the employee received  
directly from customers, and tips received from other  
employees under any tip-sharing arrangement. Both directly  
and indirectly tipped employees must report tips to you. Cash  
tips must be reported for every month, unless the cash tips  
for the month are less than $20. Stop collecting the Tier 1  
Employee tax when the employee’s compensation and tips  
for tax year 2023 reach $160,200. Collect the Tier 1

Employer Taxes  
Employers must pay both Tier 1 and Tier 2 taxes, except for  
the Tier 1 Employer tax (line 1) on qualified sick and family  
leave compensation for leave taken after March 31, 2020,  
and before April 1, 2021, and the Tier 1 Employee Additional  
Medicare Tax. Tier 1 tax is divided into two parts. The amount  
of compensation subject to each tax is different. See the  
table above for the 2023 tax rates and compensation bases.  
Concurrent employment. If two or more related  
corporations that are rail employers employ the same  
individual at the same time and pay that individual through a  
common paymaster that is one of the corporations, the  
corporations are considered a single employer. They have to  
pay, in total, no more in railroad retirement taxes than a single  
employer would. See Regulations section 31.3121(s)-1 for  
more information.  
Successor employers. Successor employers should see  
section 3231(e)(2)(C) and Pub. 15 to see if they can use the  
predecessor's compensation paid against the maximum  
compensation bases.  
If, by the 10th of the month after the month you received  
an employee's tip income report, you don't have enough  
employee funds available to withhold the employee tax, you  
may report the excess amount without withholding the related  
tax. Include the tips your employees report to you on lines 4,  
5, 6, and 7, even if you were unable to withhold the  
employee's share of tax. Then report the uncollected Tier 1  
Employee tax, Tier 1 Employee Medicare tax, Tier 1  
Employee Additional Medicare Tax withholding, and Tier 2  
Employee tax on tips on line 14. See section 6 of Pub. 15.  
Depositing Taxes  
Employee Taxes  
For Tier 1 and Tier 2 taxes, you’re either a monthly schedule  
depositor or a semiweekly schedule depositor. However, see  
under Exceptions to the Deposit Rules, later. The terms  
“monthly schedule depositor” and “semiweekly schedule  
depositor” identify which set of rules you must follow when a  
tax liability arises (for example, when you have a payday).  
They don't refer to how often your business pays its  
You must withhold the employee's part of Tier 1 and Tier 2  
taxes. See the table under Employer and Employee Taxes,  
earlier, for the tax rates and compensation bases. See Tips,  
later, for information on the employee tax on tips.  
Withholding or payment of employee tax by employer.  
You must collect the employee railroad retirement tax from  
each employee by withholding it from employee  
employees or to how often you’re required to make deposits.  
compensation. If you don't withhold the employee tax, you  
must still pay the tax. If you withhold too much or too little tax  
because you can't determine the correct amount, correct the  
amount withheld by an adjustment, credit, or refund  
according to the applicable regulations.  
If you were a monthly schedule depositor for the entire  
year, complete the Monthly Summary of Railroad Retirement  
Tax Liability in Part II of Form CT-1. If you were a semiweekly  
schedule depositor during any part of the year or you  
accumulated $100,000 or more on any day during a deposit  
period, you must complete Form 945-A, Annual Record of  
Federal Tax Liability.  
If you pay the railroad retirement tax for your employee  
rather than withholding it, the amount of the employee's  
compensation is increased by the amount of that tax. See  
Rev. Proc. 83-43,1983-1 C.B. 778, for information on how to  
figure and report the proper amounts.  
Lookback Period  
Before each year begins, you must determine the deposit  
schedule to follow for depositing Tier 1 and Tier 2 taxes for a  
4
Instructions for Form CT-1 (2023)  
     
calendar year. This is determined from the total taxes  
reported on your Form CT-1 for the calendar year lookback  
period. The lookback period is the second calendar year  
preceding the current calendar year. For example, the  
lookback period for calendar year 2024 is calendar year  
2022.  
Semiweekly Schedule Depositor  
If you’re a semiweekly schedule depositor, use the table  
below to determine when to make deposits.  
Deposit Tier 1 and Tier 2 taxes No later than...

Semiweekly schedule depositor  
Example. Green, Inc., a semiweekly schedule depositor,  
pays compensation on the last Friday of each month.  
Although Green, Inc., is a semiweekly schedule depositor,  
Green, Inc., will deposit just once a month because Green,  
Inc., pays compensation only once a month. The deposit,  
however, will be made under the semiweekly deposit  
schedule as follows: Green, Inc.’s taxes for the April 26, 2024  
(Friday), payday must be deposited by May 1, 2024  
(Wednesday). Under the semiweekly deposit rule, taxes  
arising on Wednesday through Friday must be deposited by  
the following Wednesday.  
Example. Rose Co. reported Form CT-1 taxes as follows.  
2022 Form CT-1, line 19—$49,000.  
2023 Form CT-1, line 19—$52,000.  
Rose Co. is a monthly schedule depositor for 2024  
because its Form CT-1 taxes for its lookback period  
(calendar year 2022) weren't more than $50,000. However,  
for 2025, Rose Co. is a semiweekly schedule depositor  
because the total taxes exceeded $50,000 for its lookback  
period (calendar year 2023).  
The last day of the calendar year ends the  
semiweekly deposit period and begins a new one.

years of the lookback period are considered to be zero.  
Therefore, you’re a monthly schedule depositor for the first  
and second years of your business. However, see $100,000  
CAUTION  
Deposits Due on Business Days Only  
If a deposit is required to be made on a day that isn't a  
business day, the deposit is considered to have been made  
timely if it is made by the close of the next business day. A  
business day is any day other than a Saturday, Sunday, or  
legal holiday. For example, if a deposit is due on a Friday and  
Friday is a legal holiday, the deposit will be considered timely  
if it is made by the following Monday (if that Monday is a  
business day). The term “legal holiday” for deposit purposes  
includes only those legal holidays in the District of Columbia.  
For a list of legal holidays, see section 11 of Pub. 15.  
Adjustments and the lookback rule. To determine the  
amount of taxes paid for the lookback period, use only the  
Form CT-1 taxes reported on your original return.  
Adjustments to a return for a prior period aren't taken into  
account in determining the taxes for that prior period.  
Example. Maple Co. originally reported Form CT-1 taxes  
of $45,000 for the lookback period (2022). Maple Co.  
discovered in March 2024 that the tax during the lookback  
period (2022) was understated by $10,000 and will correct  
this error with an adjustment on Form CT-1 X filed for 2022.  
Maple Co. is a monthly schedule depositor for 2024  
because the lookback period Form CT-1 taxes are based on  
the amount originally reported ($45,000), which wasn't more  
than $50,000. For purposes of the lookback rule, the $10,000  
adjustment doesn't affect either 2022 taxes or 2024 taxes.  
See Treasury Decision 9405, available at IRS.gov/irb/  
Semiweekly schedule depositors will always have at least  
3 business days following the close of the semiweekly period  
to make a deposit. If any of the 3 weekdays after the end of a  
semiweekly period is a legal holiday, you have 1 additional  
day to deposit. For example, if you have Form CT-1 taxes  
accumulated for payments made on Friday and the following  
Monday is a legal holiday, the deposit normally due on  
Wednesday may be made on Thursday (allowing 3 business  
days to make the deposit).  
When To Deposit  
Monthly Schedule Depositor  
Exceptions to the Deposit Rules  
If you’re a monthly schedule depositor, deposit employer and  
employee Tier 1 and Tier 2 taxes accumulated during a  
calendar month by the 15th day of the following month.  
Example. Spruce Co. is a monthly schedule depositor  
with seasonal employees. Spruce Co. paid compensation  
each Friday during January but didn't pay any compensation  
during February. Under the monthly schedule deposit rule,  
Spruce Co. must deposit the combined taxes for the January  
paydays by February 15. Spruce Co. doesn't have a deposit  
requirement for February (due by March 15) because no  
compensation was paid and, therefore, Spruce Co. doesn't  
have a tax liability for the month.  
The two exceptions that apply to the deposit rules are the:  
$2,500 Rule, and  
$100,000 Next-Day Deposit Rule.  
$2,500 Rule. If your total Form CT-1 taxes after adjustments  
and nonrefundable credits (line 19) for the year are less than  
$2,500 and the taxes are fully paid with a timely filed Form  
CT-1, no deposits are required. However, if you’re unsure that  
you will accumulate less than $2,500, deposit under the  
appropriate deposit rules so that you won't be subject to  
deposit penalties.

instructions for Part II, later, for instructions on how to adjust  
your tax liabilities reported on Part II or Form 945-A for  
nonrefundable credits.  
$100,000 Next-Day Deposit Rule. If you accumulate  
undeposited taxes of $100,000 or more on any day during a  
deposit period, you must deposit the taxes by the next  
business day regardless of whether you’re a monthly or  
semiweekly schedule depositor. If you're a monthly schedule  
depositor and accumulate a $100,000 tax liability on any day  
during the deposit period, you become a semiweekly  
schedule depositor on the next day and remain so for at least  
the rest of the calendar year and for the following calendar  
year. The $100,000 tax liability threshold requiring a next-day  
deposit is determined before you consider any reduction of  
your liability for nonrefundable credits. For more information,  
including an example, see frequently asked question 17 at  
Electronic Deposit Requirement  
You must use EFT to make all federal tax deposits. Generally,  
an EFT is made using EFTPS. To get more information about  
EFTPS or to enroll in EFTPS, go to EFTPS.gov or call  
800-555-4477. To contact EFTPS using TRS for people who  
are deaf, hard of hearing, or have a speech disability, dial 711  
and then provide the TRS assistant the 800-555-4477  
number above or 800-733-4829. Additional information about  
EFTPS is also available in Pub. 966.  
If you’re a monthly schedule depositor and you  
accumulate $100,000 or more on any day during the month,  
you become a semiweekly schedule depositor on the next  
day for the remainder of the calendar year and for the  
following year.  
For an EFTPS deposit to be on time, you must submit  
the deposit by 8 p.m. Eastern time the day before the  
!
CAUTION  
date the deposit is due.  
Once a semiweekly schedule depositor accumulates  
$100,000 or more in a deposit period, it must stop  
accumulating at the end of that day and begin to accumulate  
anew on the next day. The following examples explain this  
rule.  
Same-day wire payment option. If you fail to submit a  
deposit transaction on EFTPS by 8 p.m. Eastern time the day  
before the date a deposit is due, you can still make your  
deposit on time by using the Federal Tax Collection Service  
(FTCS) to make a same-day wire payment. To use the  
same-day wire payment method, you will need to make  
arrangements with your financial institution ahead of time.  
Please check with your financial institution regarding  
availability, deadlines, and costs. Your financial institution  
may charge you a fee for payments made this way. To learn  
more about the information you will need to give your  
financial institution to make a same-day wire payment, go to  
Accuracy of Deposits Rule. You’re required to deposit  
100% of your railroad retirement taxes on or before the  
deposit due date. However, penalties won't be applied for  
depositing less than 100% if both of the following conditions  
are met.  
1. Any deposit shortfall doesn't exceed the greater of  
$100 or 2% of the amount of taxes otherwise required to be  
deposited.  
Example of $100,000 Next-Day Deposit Rule.  
Fir Co. is a semiweekly schedule depositor. On Monday, Fir  
Co. accumulates taxes of $110,000 and must deposit this  
amount by Tuesday, the next business day. On Tuesday, Fir  
Co. accumulates additional taxes of $30,000. Because the  
$30,000 isn't added to the previous $110,000, Fir Co. must  
deposit the $30,000 by Friday using the semiweekly deposit  
schedule.  
Example of $100,000 Next-Day Deposit Rule during  
the first year of business. Elm, Inc., started its business on  
Monday, May 6, 2024. Because this was the first year of its  
business, its Form CT-1 taxes for its lookback period (2022)  
are considered to be zero, and Elm, Inc., is a monthly  
schedule depositor. On Wednesday, May 8, it paid  
compensation for the first time and accumulated taxes of  
$40,000. On Friday, May 10, it paid compensation and  
accumulated taxes of $60,000, bringing its total accumulated  
(undeposited) taxes to $100,000. Because Elm, Inc.,  
accumulated $100,000 or more on May 10 (Friday), Elm, Inc.,  
must deposit the $100,000 by May 13 (Monday), the next  
business day. Elm, Inc., became a semiweekly schedule  
depositor on May 11. Elm, Inc., will be a semiweekly  
schedule depositor for the rest of 2024 and for 2025.  
Example of when $100,000 Next-Day Deposit Rule  
doesn't apply. Oak Co., a semiweekly schedule depositor,  
accumulated taxes of $95,000 on a Tuesday (of a  
2. The deposit shortfall is paid or deposited by the  
shortfall makeup date for each type of depositor as described  
below.  
Monthly schedule depositor. Deposit the shortfall or pay  
it with your return by the due date of Form CT-1. You may pay  
the shortfall with Form CT-1 even if the amount is $2,500 or  
more.  
Semiweekly schedule depositor. Deposit the shortfall  
Saturday-through-Tuesday deposit period) and accumulated  
$10,000 on Wednesday (of a Wednesday-through-Friday  
deposit period). Because the $10,000 was accumulated in a  
deposit period different from the one in which the $95,000  
was accumulated, the $100,000 Next-Day Deposit Rule  
doesn’t apply. Thus, Oak Co. must deposit $95,000 by Friday  
and $10,000 by the following Wednesday.  
Reducing your deposits for the credit for qualified  
sick and family leave compensation. Employers eligible  
to claim the credit for qualified sick and family leave  
compensation paid in 2023 for leave taken after March 31,  
2020, and before October 1, 2021, can reduce their deposits  
by the amount of their anticipated credit. Employers won't be  
subject to a failure-to-deposit (FTD) penalty for reducing their  
deposits if certain conditions are met. See the instructions for  
by the earlier of the first Wednesday or Friday on or after the  
15th of the month following the month in which the shortfall  
occurred. For example, if a semiweekly schedule depositor  
has a deposit shortfall during February 2024, the shortfall  
makeup date is March 15, 2024 (Friday).  
Penalties and Interest  
The law provides penalties for failure to file a return, late filing  
of a return, late payment of taxes, failure to make deposits,  
and late deposits unless filing and/or paying late is due to  
reasonable cause and not due to willful neglect. Interest is  
charged on taxes paid late at the rate set by law. For more  
information, see Pub. 15. Deposit or pay your taxes when  
they are due, unless you meet the requirements discussed in

Instructions for Form CT-1 (2023)  
       
If you receive a notice about a penalty after you file this  
return, reply to the notice with an explanation and we will  
determine if you meet reasonable cause criteria. Don't attach  
an explanation when you file your return.  
Qualified Sick Leave Compensation and  
Qualified Family Leave Compensation  
Qualified sick leave compensation. For purposes of the  
credit for qualified sick and family leave compensation,  
qualified sick leave compensation is compensation  
(determined without regard to the exclusions under section  
3231(e)(1)) paid under the Emergency Paid Sick Leave Act  
(EPSLA) or the Emergency Family and Medical Leave  
Expansion Act (Expanded FMLA) as enacted under the  
FFCRA and amended for purposes of the ARP. See the  
instructions for line 16 for information about the credit for  
qualified sick and family leave compensation paid in 2023 for  
leave taken after March 31, 2020, and before April 1, 2021,  
and the instructions for line 17b for information about the

Use Form 843 to request abatement of assessed  
penalties or interest. Don't request abatement of assessed  
penalties or interest on Form CT-1 or Form CT-1 X.  
Order in which deposits are applied. Generally, tax  
deposits are applied first to the most recent tax liability within  
the specified tax period to which the deposit relates. If you  
receive an FTD penalty notice, you may designate how your  
payment is to be applied in order to minimize the amount of  
the penalty. You must respond within 90 days of the date of  
the notice. Follow the instructions on the notice you received.

from the employer or business, the trust fund recovery  
penalty may be imposed on all persons who are determined  
by the IRS to be responsible for collecting, accounting for, or  
paying over these taxes, and who acted willfully in not doing  
so. For more information, see Trust Fund Recovery Penalty in

Son or daughter. A son or daughter must generally have  
been under 18 years of age or incapable of self-care because  
of a mental or physical disability. A son or daughter includes  
a biological child, adopted child, stepchild, foster child, legal

daughter, earlier, for more information. For leave taken after  
March 31, 2021, and before October 1, 2021, the leave can  
be granted for any other reason provided by the EPSLA, as  
amended for purposes of the ARP.  
For leave taken after March 31, 2020, and before April 1,  
2021, the first 10 days for which an employee takes leave  
may be unpaid. During this period, employees may use other  
forms of paid leave, such as qualified sick leave, accrued sick  
leave, annual leave, or other paid time off. After an employee  
takes leave for 10 days, the employer provides the employee  
paid leave (that is, qualified family leave compensation) for  
up to 10 weeks. For leave taken after March 31, 2021, and  
before October 1, 2021, the 10-day rule discussed above  
doesn't apply and the paid leave can be provided for up to 12  
weeks.  
Rate of pay and limit on compensation. The rate of pay  
must be at least two-thirds of the employee's regular rate of  
pay (as determined under the Fair Labor Standards Act of  
1938), multiplied by the number of hours the employee would  
have otherwise been scheduled to work. For leave taken after  
March 31, 2020, and before April 1, 2021, the qualified family  
leave compensation can't exceed $200 per day or $10,000 in  
the aggregate per employee. For leave taken after March 31,  
2021, and before October 1, 2021, the limit resets and the  
total qualified family leave compensation can't exceed $200  
per day or $12,000 in the aggregate per employee.  
Limits on qualified sick leave compensation. The  
EPSLA, as amended for purposes of the ARP, provides  
different limitations for different circumstances under which  
qualified sick leave compensation is paid. For paid sick leave  
qualifying under (1), (2), or (3) above, the amount of qualified  
sick leave compensation is determined at the employee's  
regular rate of pay, but the compensation may not exceed  
$511 for any day (or portion of a day) for which the individual  
is paid sick leave. For paid sick leave qualifying under (4), (5),  
or (6) above, the amount of qualified sick leave compensation  
is determined at two-thirds the employee's regular rate of pay,  
but the compensation may not exceed $200 for any day (or  
portion of a day) for which the individual is paid sick leave.  
The EPSLA also limits each individual to a maximum of up to  
80 hours of paid sick leave in total for leave taken after March  
31, 2020, and before April 1, 2021. The ARP resets this limit  
at 80 hours of paid sick leave for leave taken after March 31,  
2021, and before October 1, 2021. Therefore, for leave taken  
after March 31, 2020, and before April 1, 2021, the maximum  
amount of paid sick leave compensation can't exceed $5,110  
for an employee for leave under (1), (2), or (3), and it can't  
exceed $2,000 for an employee for leave under (4), (5), or  
(6). These maximum amounts also reset and apply to leave  
taken after March 31, 2021, and before October 1, 2021.

CAUTION  
If you’re a semiweekly schedule depositor or if you  
accumulate $100,000 or more in tax liability on any day in a  
deposit period, you must complete Form 945-A and file it with  
Form CT-1. Don't complete lines I–V if you file Form 945-A.

If you want to allow an employee of your business, a return  
preparer, or another third party to discuss your Form CT-1  
with the IRS, check the “Yes” box in the Third-Party Designee  
section. Also, enter the designee's name, phone number, and  
any five digits that person chooses as their personal  
identification number (PIN).  
nonrefundable portion of the credit is used. Any credit for  
qualified sick and family leave compensation paid in 2023 for  
leave taken after March 31, 2020, and before April 1, 2021,  
that is remaining at the end of the year because it exceeds

By checking “Yes” you authorize the IRS to talk to the  
person you named (your designee) about any questions we  
may have while we process your return. You also authorize  
your designee to do all of the following.

reported on Part II or Form 945-A.  
Example. Maple Co. is a monthly schedule depositor that  
pays employees every Friday. In 2023, Maple Co. had pay  
dates every Friday starting on January 6, 2023. Maple Co.  
paid qualified sick and family leave compensation on March  
10 and March 17 for leave taken after March 31, 2020, and  
before April 1, 2021. The nonrefundable portion of the credit  
for qualified sick and family leave compensation for the year  
is $3,000. On Part II, Maple Co. will use the $3,000 to reduce  
the liability for the January 6 pay date, but not below zero. If  
any nonrefundable portion of the credit remains, Maple Co.  
applies it to the liability for the January 13 pay date, then the  
January 20 pay date, and so forth until the entire $3,000 is  
used.  
Give us any information that is missing from your return.  
Call us for information about processing your return.  
Respond to certain IRS notices that you have shared with  
the designee about math errors and return preparation. The  
IRS won't send notices to your designee.  
You’re not authorizing the designee to receive any refund  
check, bind you to anything (including additional tax liability),  
or otherwise represent you before the IRS. If you want to  
expand the designee's authority, see Pub. 947.  
The authorization will automatically expire 1 year from the  
due date (without regard to extensions) for filing your Form  
CT-1. If you or your designee wants to revoke this  
authorization, send the revocation or withdrawal to the IRS  
office at which you file your Form CT-1.  
Nonrefundable portion of credit for qualified sick and  
family leave compensation for leave taken after March

family leave compensation paid in 2023 for leave taken after  
March 31, 2021, and before October 1, 2021, is limited to the
