3800 Instructions for Form 3800

Caution: DRAFT—NOT FOR FILING
This is an early release draft of an IRS tax form, instructions, or
publication, which the IRS is providing for your information as a courtesy.
Do not file draft forms. Also, do not rely on draft forms, instructions, and
publications for filing. We generally do not release drafts of forms until we
believe we have incorporated all changes. However, unexpected issues
sometimes arise, or legislation is passed, necessitating a change to a draft
form. In addition, forms generally are subject to OMB approval before they
can be officially released. Drafts of instructions and publications usually
have at least some changes before being officially released.
Early release drafts are at IRS.gov/DraftForms, and may remain there
even after the final release is posted at IRS.gov/DownloadForms. All
information about all forms, instructions, and pubs is at IRS.gov/Forms.
Almost every form and publication also has its own page on IRS.gov. For
example, the Form 1040 page is at IRS.gov/Form1040; the Publication 17
page is at IRS.gov/Pub17; the Form W-4 page is at IRS.gov/W4; and the
Schedule A (Form 1040) page is at IRS.gov/ScheduleA. If typing in a link
above instead of clicking on it, be sure to type the link into the address bar
of your browser, not in a Search box. Note that these are friendly shortcut
links that will automatically go to the actual link for the page.
If you wish, you can submit comments about draft or final forms,
instructions, or publications at IRS.gov/FormsComments. We cannot
respond to all comments due to the high volume we receive. Please note that
we may not be able to consider many suggestions until the subsequent
revision of the product.

Code unless otherwise noted.

Future Developments

For the latest information about
developments related to Form 3800 and
its instructions, such as legislation
enacted after they were published, go to
IRS.gov/Form3800.

What’s New

• The Tax Cut and Jobs Act repealed the
corporate alternative minimum tax for tax
years beginning after 2017. As a result,
corporations will enter zero (-0-) in Part II,
line 14.
• The Tax Cut and Jobs Act added the
employer credit for paid family and
medical leave (Form 8994). This credit is
reported in Part III, line 4j. See the
Instructions for Form 8994 for more
information.

General Instructions
Partnerships and S corporations

TIP must always complete the source

credit form. All other filers whose
only source for a credit listed on Form
3800, Part III, is from a partnership, S
corporation, estate, trust, or cooperative
can report the credit directly on Form
3800. The following exceptions apply.

• You are claiming the investment credit
(Form 3468) or the biodiesel and
renewable diesel fuels credit (Form 8864)
in Part III with box A or B checked.
• You are an estate or trust and the
source credit must be allocated to
beneficiaries. For more details, see the
instructions for Form 1041, U.S. Income
Tax Return for Estates and Trusts,
Schedule K-1, box 13.
• You are a cooperative and the source
credit can or must be allocated to patrons.
For more details, see the instructions for
Form 1120-C, U.S. Income Tax Return for
Cooperative Associations, Schedule J,
line 5c.

Who Must File

You must file Form 3800 to claim any of
the general business credits.

Sep 26, 2018

The carryforward may have to be
reduced in the event of any
CAUTION recapture event (change in
ownership, change in use of property,
etc.). If a section 1603 grant is received,
the carryforward must be reduced to zero.
For further information, see Form 4255,
Recapture of Investment Credit.

!

If you can't use part or all of your
general business credit because of the tax
liability limit (Part II, line 38, is less than the
sum of Part I, line 6, and Part II, lines 25
and 36), carry the unused credit back 1
year. If the credit is for oil and gas
production from marginal wells, the
carryback period is 5 years. To carry back
an unused credit, file an amended return
(Form 1040X, Amended U.S. Individual
Income Tax Return, Form 1120X,
Amended U.S. Corporation Income Tax
Return, or other amended return) for the
prior tax year or an application for tentative
refund (Form 1045, Application for
Tentative Refund, or Form 1139,
Corporation Application for Tentative
Refund). Generally, if you file an
application for a tentative refund, it must
be filed by the end of the tax year following
the tax year in which the credit arose.
No part of the unused credit for

TIP any year attributable to any credit

can be carried back to any tax
year before the first tax year for which that
credit was first allowable. See Credit
Ordering Rule, later, to determine which
credits are allowed first.
If you have an unused credit after
carrying it back 1 year (5 years for a credit
from oil and gas production from marginal
wells), carry it forward to each of the 20
tax years after the year of the credit. Any
qualified business credits (as defined in
section 196(c)) that are unused after the
last tax year of the 20-year carryforward
period (or at the time an individual
taxpayer dies or other taxpayer, such as a
corporation or partnership, ceases to
exist) may be taken as a deduction in the
earlier of:
• The tax year following the last tax year
of the 20-year carryforward period, or
• The tax year in which the individual
taxpayer dies or other taxpayer ceases to
exist.
Cat. No. 10622Q

Figuring the carryforward if a payroll
tax credit election is made. Qualified
small businesses electing to claim a
portion of the research credit as a payroll
tax credit must adjust the research credit
carryforward for the amount of the credit
elected as a payroll tax credit on Form
6765.
The unused credit for the current year
is determined by reducing the amount on
Part I, line 6 and Part II, line 36 by the
amount on Form 6765, line 44. If you have
amounts on both Part I, line 6 and Part II,
line 36, the reduction is made
proportionately. No amount elected as a
payroll tax credit can be used to offset the
current year tax liability nor can it be
included in the carryforward or carryback
calculation.

Carryforward of the energy credit and
the renewable electricity credit. The
energy credit must be recaptured in full if a
grant is paid under Public Law 111-5,
section 1603, for investment in energy
property that an energy credit was
previously claimed or for investment in
renewable energy property that an
election was made to treat the property as
energy property. Recapture is applicable
to those amounts previously constituting
the qualified basis for an energy credit,
including progress expenditures, that are
also the basis for the 1603 grant.
Recapture is accomplished as follows.
1. Any portion of the energy credit
related to that property that was used to
offset tax in a prior tax year must be added
to tax in the tax year the 1603 grant is
received. Recaptured tax is calculated on
Form 4255.
2. Any carryforward of the energy
credit related to that property is reduced to
zero to recapture the unused portion of the
credit.
See Form 4255 for any other recapture
event (change in ownership or change in
use of property, etc.).
Carryforward of certain Form 6478
credits. The alcohol mixture credit, the
alcohol credit, and the small ethanol
producer credit expired for fuels sold or
used after 2011. The unused alcohol
mixture credits, alcohol credits, and small
ethanol producer credits (for all tax years)
can't be carried to a tax year beginning
after 2014.

Change in Filing or Marital
Status

Your general business credit is limited to
your tax liability. Therefore, if you filed a
joint return in a carryback or carryforward
year and your marital status or filing status
has changed, you may need to figure your
separate tax liability in that carryback or
carryforward year. This would apply if:
• You filed as single in the credit year, but
filed a joint return in the carryback or
carryforward year;
• You filed a joint return in the credit year,
but filed a joint return with a different
spouse in the carryback or carryforward
year; or
• You were married and filed a separate
return in the credit year, but filed a joint
return with the same or a different spouse
in the carryback or carryforward year.

Credit Ordering Rule

General business credits reported on
Form 3800 are treated as used on a
first-in, first-out basis by offsetting the
earliest-earned credits first. Therefore, the
order in which the credits are used in any
tax year is:
• Carryforwards to that year, the earliest
ones first;
• The general business credit earned in
that year; and
• The carryback to that year.

• Low sulfur diesel fuel production credit
(Form 8896).
• Credit for oil and gas production from
marginal wells (Form 8904).
• Distilled spirits credit (Form 8906).
• Nonconventional source fuel credit
(carryforward only).
• Energy efficient home credit
(Form 8908).
• Energy efficient appliance credit
(carryfoward only).
• Alternative motor vehicle credit
(Form 8910).
• Alternative fuel vehicle refueling
property credit (Form 8911).
• Mine rescue team training credit
(Form 8923).
• Agricultural chemicals security credit
(carryforward only).
• Credit for employer differential wage
payments (Form 8932).
• Carbon dioxide sequestration credit
(Form 8933).
• Qualified plug-in electric drive motor
vehicle credit (Form 8936).
• Qualified plug-in electric vehicle credit
(carryforward only).
• Credit for small employer health
insurance premiums (Form 8941).
• Employee retention credit (Form
5884-A).
• Employer credit for paid family and
medical leave (Form 8994).
• General credits from an electing large
partnership (Schedule K-1 (Form
1065-B)).

DRAFT AS OF
September 26, 2018
Determine your separate tax liability in
the carryback or carryforward year as
follows.
1. Figure your tax for the carryback or
carryforward year as though you were
married filing a separate return.
2. Figure your spouse's tax in that
year as though he or she was married
filing a separate return.
3. Add the amounts in steps (1)
and (2).
4. Divide the amount in step (1) by the
amount in step (3). The result should be
rounded to at least three decimal places.
5. Multiply the decimal in step (4) by
the total tax shown on your joint return for
the carryback or carryforward year. The
result is your separate tax liability and a
carryback or carryforward credit is applied
against this amount only.
Although your carryback or
carryforward of the credit is limited to your
separate tax liability, the amount of your
refund resulting from the carryback or
carryforward is further limited to your
share of the joint overpayment. This is
found by subtracting your separate tax
liability (as determined above) from your
contribution toward the payment.
Unless you have an agreement or clear
evidence of each spouse's contribution
toward the payment of the joint liability,
your contribution includes the tax withheld
on your wages and your share of the joint
estimated tax or tax paid with the return.
Your share of these payments is found by
using the same formula used in
determining your separate tax liability.
Substitute the joint estimated tax, or tax
paid with the return, for the tax in step (5).
If the original return for the carryback year
resulted in an overpayment, reduce your
contribution by your share of the refund.
Attach a copy of the computation to
your amended return or application for
tentative refund.

If your general business credits exceed
your tax liability limit, the credits are used
in the following order and based on the
order shown under Order in which credits
are used next.

• Credits reported on line 2 of all Parts III
with boxes A, B, C, and D checked.
• Credits reported on Part II, line 25.
• Non-ESBC credits reported on line 5 of
all Parts III with boxes A, B, C, and D
checked.
• ESBC credits reported on line 6 of all
Parts III with box G checked.

Order in which credits are used. When
relevant, the components of the general
business credit reported on Form 3800
arising in a single tax year are used in the
following order.
• Investment credit (in the following
order—rehabilitation credit, energy credit,
qualifying advanced coal project credit,
qualifying gasification project credit, and
qualifying advanced energy project credit)
(Form 3468).
• Qualifying therapeutic discovery project
credit (carryforward only).
• Work opportunity credit (Form 5884).
• Biofuel producer credit (Form 6478).
• Credit for increasing research activities
(Form 6765).
• Low-income housing credit
(Form 8586, Part I only).
• Enhanced oil recovery credit (Form
8830).
• Disabled access credit (Form 8826).
• Renewable electricity, refined coal, and
Indian coal production credit (Form 8835).
• Empowerment zone employment credit
(Form 8844).
• Renewal community employment credit
(carryforward only).
• Indian employment credit (Form 8845).
• Employer social security and Medicare
taxes paid on certain employee tips
(Form 8846).
• Orphan drug credit (Form 8820).
• New markets credit (Form 8874).
• Credit for small employer pension plan
startup costs (Form 8881).
• Credit for employer-provided child care
facilities and services (Form 8882).
• Qualified railroad track maintenance
credit (Form 8900).
• Biodiesel and renewable diesel fuels
credit (Form 8864).

Although these credits are

TIP aggregated on Form 3800, keep a

separate record of each credit,
including whether the credit was an
eligible small business credit, to ensure
proper accounting of the credits.

Eligible Small Business

An eligible small business is:
• A corporation whose stock is not
publicly traded,
• A partnership, or
• A sole proprietorship.
The average annual gross receipts of
the corporation, partnership, or sole
proprietorship for the 3-tax-year period
preceding the tax year of the credit cannot
exceed $50 million. Gross receipts for any
tax year must be reduced by returns and
allowances made during the year. Any
reference to your business also includes a
reference to any predecessor of your
business.
If your business was not in existence
for the entire 3-year period, base your
average annual gross receipts on the
period your business existed. Also, if your
business had a tax year of less than 12
months, your gross receipts must be
annualized by multiplying the gross
receipts for the short period by 12 and
Instructions for Form 3800 (2018)

dividing the result by the number of
months in the short period.
Member of controlled group,
business under common control, or
affiliated group. For purposes of the
gross receipts test, all members of a
controlled group of corporations (as
defined in section 52(a)) and all members
of a group of businesses under common
control (as defined in section 52(b)) are
treated as a single person, and all
employees of the members of an affiliated
service group (as defined in sections
414(m) and (o)) shall be treated as
employed by a single person.

Limitation on Certain Credits
The aggregate amount from each credit
form is usually reported on the appropriate
line of Form 3800, Part III, for the
applicable boxes A and B, to reflect
self-generated credit sources and all
pass-through entity sources. However,
certain credits have limitations imposed.
They include:
• Form 3468, Part III, line 12p—$4,000
limitation for qualified small wind energy
property (reported on Part III, line 4a);
• Form 8826, line 8—$5,000 limitation for
the overall credit (reported on Part III,
line 1e);
• Form 8881, line 5—$500 limitation for
the overall credit (reported on Part III,
line 1j); and
• Form 8882, line 7—$150,000 limitation
for the overall credit (reported on Part III,
line 1k).
In situations where there is a limitation
on the credit amount, the limited amount
Instructions for Form 3800 (2018)

allowed is allocated pro rata and anything
above the limitation is lost.

Lines 1a and 4a

If you are a cooperative described in
section 1381(a), you must allocate to your
patrons the investment credit in excess of
your tax liability limit. Allocate to your
patrons the portion, if any, of the
investment credit on Part I, line 6, or Part
II, line 36, in excess of Part II, line 16 or
line 29, respectively. While any excess is
allocated to patrons, any credit recapture
