Instructions for Form SS-4  
Application for Employer Identification Number (EIN)  
(Rev. December 2023)  
Section references are to the Internal Revenue Code unless  
otherwise noted.  
Keep Form SS-4 information current. Use Form 8822-B to report  
changes to your responsible party, address or location. Changes in  
responsible parties must be reported to the IRS within 60 days.  
General Instructions  
File only one Form SS-4. Generally, a sole proprietor should file  
only one Form SS-4 and needs only one EIN, regardless of the  
number of businesses operated as a sole proprietorship or trade  
names under which a business operates. However, if a sole  
proprietorship incorporates or enters into a partnership, a new EIN is  
required. Also, each corporation in an affiliated group must have its  
own EIN.  
Use these instructions to complete Form SS-4, Application for  
Employer Identification Number (EIN). Also, see Do I Need an EIN?  
on page 2 of Form SS-4.  
Future Developments  
For the latest information related to Form SS-4 and its instructions,  
such as legislation enacted after they were published, go to IRS.gov/  
EIN applied for, but not received. If you don’t have an EIN by the  
time a return is due, write “Applied For” and the date you applied in  
the space shown for the number. Don’t show your SSN as an EIN on  
returns. If you don’t have an EIN by the time a tax deposit is due,  
send your payment to the Internal Revenue Service Center for your  
filing area as shown in the instructions for the form that you are filing.  
Make your check or money order payable to the “United States  
Treasury” and show your name (as shown on Form SS-4), address,  
type of tax, period covered, and date you applied for an EIN.  
What's New  
Line 14. Form SS-4, line 14, now reflects the ceiling for wages paid  
by employers in U.S. territories electing to file Form 944. This  
information has been available in the instructions for Line 14.  
Indian tribal governments/enterprises. We added guidance to  
Line 1 and Line 9a, later, for Indian tribal governments, and for  
certain tribal enterprises that are not recognized as separate entities  
for federal tax purposes, under Regulations section 301.7701-1(a)  
(3).  
For information about EINs and federal tax deposits, see  
Pub. 15.  
TIP  
To ensure fair and equitable treatment for all taxpayers, EIN  
issuances are limited to one per responsible party, per day.  
For trusts, the limitation is applied to the grantor, owner, or  
Forms SS-4 and SS-4(sp) absorb Form SS-4PR. Form SS-4PR,  
Solicitud de Número de Identificación Patronal, will no longer be  
available after 2023. Instead, if you are an employer in Puerto Rico,  
you will file Form SS-4. If you prefer your form and instructions in  
Spanish, you can file new Form SS-4 (sp), Solicitud de Número de  
Identificación del Empleador (EIN).

CAUTION  
trustor. For estates, the limitation is applied to the decedent  
(decedent estate) or the debtor (bankruptcy estate). This limitation is  
applicable to all requests for EINs whether online, telephone, fax, or  
mail.  
Pub. 51 and Pub. 80 rolled into Pub. 15, plus new Pub. 15(sp).  
Pub. 51, Agricultural Employer’s Tax Guide, and Pub. 80, Federal  
Tax Guide for Employers in the U.S. Virgin Islands, Guam, American  
Samoa, and the Commonwealth of the Northern Mariana Islands,  
will no longer be available after 2023. Instead, information specific to  
agricultural employers and employers in the U.S. territories will be  
included in Pub. 15, Employer’s Tax Guide, beginning with the Pub.  
15 for use in 2024. Beginning in 2024, there will be a new Pub. 15  
(sp) that is a Spanish-language version of Pub. 15.  
How To Apply for an EIN  
You can apply for an EIN online (only for applicants in the U.S. or  
U.S. territories), by telephone (only for applicants outside of the U.S.  
or U.S. territories), by fax, or by mail, depending on how soon you  
need to use the EIN. Use only one method for each entity so you  
don’t receive more than one EIN for an entity.  
Apply for an EIN online. If you have a legal residence, principal  
place of business, or principal office or agency in the U.S. or U.S.  
territories, you can receive an EIN online and use it immediately to  
file a return or make a payment. Go to the IRS website at IRS.gov/  
EIN.  
The principal officer, general partner, grantor, owner, trustor, etc.,  
must have a valid taxpayer identification number (SSN, EIN, or ITIN)  
in order to use the online application. Taxpayers who apply online  
have an option to view, print, and save their EIN assignment notice  
at the end of the session. Authorized third-party designees, see  
Line 18, later.  
Purpose of Form  
Use Form SS-4 to apply for an EIN. An EIN is a 9-digit number (for  
example, 12-3456789) assigned to sole proprietors, corporations,  
partnerships, estates, trusts, and other entities for tax filing and  
reporting purposes. The information you provide on this form will  
establish your business tax account.

Lines 8a–8c. Limited liability company (LLC) information. An  
LLC is an entity organized under the laws of a state or foreign  
country as a limited liability company. For federal tax purposes, an  
LLC may be treated as a partnership or corporation or be  
disregarded as an entity separate from its owner.  
By default, a domestic LLC with only one member is disregarded  
as an entity separate from its owner and must include all of its  
income and expenses on the owner's tax return (for example,  
Schedule C (Form 1040)). For more information on single-member  
LLCs, see Disregarded entities, later.  
Also, by default, a domestic LLC with two or more members is  
treated as a partnership. A domestic LLC may file Form 8832 to  
avoid either default classification and elect to be classified as an  
association taxable as a corporation. For more information on entity  
classifications (including the rules for foreign entities), see Form  
8832 and its instructions.

trusts, enter the name of the trustee. For estates, enter the name of

Enter the individual's first name, middle initial, and last name.  
Lines 4a–4b. Mailing address. Enter the mailing address for the  
entity's correspondence. If the entity's address is outside the United  
States or its territories, you must enter the city, province or state,  
postal code, and the name of the country. Don't abbreviate the  
country name. If line 3 is completed, enter the address for the  
executor, trustee, or “care of” person. Generally, this address will be  
used on all tax returns.  
If the entity is filing Form SS-4 only to obtain an EIN for Form  
8832, use the same address where you would like to have the  
acceptance or nonacceptance letter sent.  
File Form 8822-B to report any subsequent changes to the  
entity's mailing address.  
TIP  
Don't file Form 8832 if the LLC accepts the default  
classifications above. If the LLC timely files Form 2553, it will

Lines 5a–5b. Street address. Provide the entity's physical address  
only if different from its mailing address shown on lines 4a–4b. Don't  
enter a P.O. box number here. If the entity's address is outside the

corporation election as long as it meets all other requirements to  
qualify as an S corporation. The LLC doesn't need to file Form 8832  
in addition to Form 2553. See the Instructions for Form 2553.  
Line 9a. Type of entity. Check the box that best describes the type  
of entity applying for the EIN. If you're an alien individual with an ITIN  
previously assigned to you, enter the ITIN in place of a requested  
SSN.  
Line 6. County and state where principal business is located.  
Enter the entity's primary physical location.  
Lines 7a–7b. Name of responsible party. Enter the full name (first  
name, middle initial, last name, if applicable) and SSN, ITIN, or EIN  
of the entity's responsible party.  
This isn't an election for a tax classification of an entity. See  
!
CAUTION  
Responsible party defined. The “responsible party” is the  
person who ultimately owns or controls the entity or who exercises  
ultimate effective control over the entity. The person identified as the  
responsible party should have a level of control over, or entitlement  
to, the funds or assets in the entity that, as a practical matter,  
enables the person, directly or indirectly, to control, manage, or  
direct the entity and the disposition of its funds and assets. Unless  
the applicant is a government entity, the responsible party  
must be an individual (that is, a natural person), not an entity.  
Sole proprietor. Check this box if you file Schedule C or  
Schedule F (Form 1040) and have a qualified plan, or are required to  
file excise, employment, alcohol, tobacco, or firearms returns, or are  
a payer of gambling winnings. Enter your SSN or ITIN in the space  
provided. If you're a nonresident alien with no effectively connected  
income from sources within the United States, enter “N/A.” You don't  
need to enter an SSN or ITIN.  
Corporation. This box is for any corporation other than a  
personal service corporation. If you check this box, enter the income  
tax form number to be filed by the entity in the space provided.  
For entities with shares or interests traded on a public exchange,  
or which are registered with the Securities and Exchange  
Commission, “responsible party” is (a) the principal officer, if the  
entity is a corporation; or (b) a general partner, if a partnership. The  
general requirement that the responsible party be an individual  
applies to these entities. For example, if a corporation is the general  
partner of a publicly traded partnership for which Form SS-4 is filed,  
then the responsible party of the partnership is the principal officer of  
the corporation.  
Unless you are a church, or church-controlled organization,  
if you are a corporation that is a nonprofit entity, check the  
“other nonprofit organization" box, and specify the purpose.  
TIP  
If you entered “1120-S” after the Corporation checkbox, the  
corporation must file Form 2553 no later than the 15th day of

taxation, law enforcement, and civil authority. If you're unsure  
whether or not your organization is a government, search “What are  
government entities?” at IRS.gov for clarification.  
Federal government. The federal government is made up of the  
Executive, Legislative, and Judicial branches, as well as  
independent federal agencies. Unions, Veterans of Foreign Wars  
(VFW) organizations, and political organizations aren't federal

Alaska Natives, but only if the Secretary of the Treasury (after  
consultation with the Secretary of the Interior) determines that the  
governing body exercises governmental functions.  
Withholding agent. If you're a withholding agent required to file  
Form 1042, check the Other box and enter “Withholding agent.”  
Disregarded entities. A disregarded entity is an eligible entity  
that is treated as an entity not separate from its single owner for  
income tax purposes. Disregarded entities include single-member  
limited liability companies (LLCs) and certain qualified foreign  
entities. See the instructions for Forms 8832 and 8869, and  
Regulations section 301.7701-3 for more information on domestic  
and foreign disregarded entities.  
The disregarded entity is required to use its name and EIN for  
reporting and payment of employment taxes; to register for excise  
tax activities on Form 637; to pay and report excise taxes reported  
on Forms 720, 730, 2290, and 11-C; to claim any refunds, credits,  
and payments on Form 8849; and where a U.S. disregarded entity is  
wholly owned by a foreign person, to file information returns on Form  
5472. See the instructions for the employment and excise tax returns  
and Form 5472 for more information.  
Complete Form SS-4 for disregarded entities as follows.

because it is required to report and pay employment and excise  
taxes, or for non-federal purposes such as a state requirement,  
check the Other box for line 9a and write “Disregarded entity” (or  
“Disregarded entity-sole proprietorship” if the owner of the  
disregarded entity is an individual).  
If the disregarded entity is requesting an EIN for purposes of filing  
Form 5472, as required under section 6038A for a U.S. disregarded  
entity that is wholly owned by a foreign person, check the Other box  
for line 9a and write “Foreign-owned U.S. disregarded entity-Form  
5472.”  
If the disregarded entity is requesting an EIN for purposes of filing  
Form 8832 to elect classification as an association taxable as a
