the entity level for that property, you
must file this form for your tax year that

entity's recomputation year. The
pass-through entity will provide on
Schedule K-1 the information you need

General Instructions
Future Developments
For the latest information about
developments related to Form 8866 and
its instructions, such as legislation
enacted after they were published, go to
determining the depreciation deduction
for the property under the income
forecast method.
Change of Taxpayer
What's New
If the taxpayer deducting depreciation
under the income forecast method
changes prior to the recomputation
year, the taxpayer as of the end of the
recomputation year will be responsible
for the payment of interest, if any, due
for any year in which the property was
depreciated under the income forecast
method. Generally, only the taxpayer
that had depreciated property under the
income forecast method in a year that
an overpayment occurred may request
a refund of interest on the overpayment.
Additional Costs
The tax rate used for the interest
computation for individuals,
Any costs incurred after the property
was placed in service (that is not treated
as separate property—see below) are
taken into account by discounting (using
the federal mid-term rate determined
under section 1274(d) as of the time the
cost was incurred) the cost to its value
as of the date the property was placed
in service. However, you may elect not
to apply this discounting rule to any
property.
corporations, and certain pass-through
entities has changed. See the
instructions for line 6, later.
Purpose of Form
Use Form 8866 to figure the interest due
or to be refunded under the look-back
method of section 167(g)(2) for property
placed in service after September 13,
1995, that is depreciated under the
income forecast method as described in
section 167(g).

Who Must File
Pass-Through Entities
For taxpayers other than
partnerships, include any interest due in
the amount to be entered for total tax
(after credits and other taxes) on your
return (for example, 2018 Form 1040,
line 15; or 2018 Form 1120, Schedule J,
line 9d, etc.). Next to the entry space,
write “From Form 8866” and the amount
of interest due.
General Rule
A pass-through entity (partnership, S
corporation, or trust) that is not closely
held must apply the look-back method
at the entity level to any property for
which substantially all of the gross
income is from U.S. sources. A
You generally must file Form 8866 to
figure interest under the look-back
method for each recomputation year for
property placed in service after
September 13, 1995, that you
depreciate under the income forecast
method.
Exception. The look-back method
does not apply for any property that had
an unadjusted basis (total capitalized
cost) of $100,000 or less at the end of
the recomputation year.
pass-through entity is considered
closely held if, at any time during any
tax year for which there is income
related to the property, 50% or more (by
value) of the beneficial interests in the
entity is held (directly or indirectly) by or
for five or fewer persons. For this
purpose, rules similar to the constructive
ownership rules of section 1563(e)
apply.
For partnerships, write “From Form
8866” and any interest due in the
bottom margin of the tax return, and
attach a check or money order for the
full amount payable to “United States
Treasury.” Write the partnership's
employer identification number (EIN),
daytime phone number, and “Form
8866 Interest” on the check or money
order.
