MO-1120 CORPORATION INCOME TAX

call Business Registration at (573) 751-5860.

Every corporation, as defined in Chapter 143, RSMo, is required
to file a return of income in Missouri for each year it is required
to file a federal income tax return and the corporation’s gross
income from sources within Missouri is $100 or more. The tax on
corporations will not apply to:

TIME AND PLACE OF FILING AND PAYMENT
Corporation income tax is due on or before the 15th day of the
fourth month following the end of the tax year. Example: Taxable
period of January 1, 2023, to December 31, 2023; due April 15, 2024.

•	 A corporation, which by reason of its purposes and activities, is
exempt from federal income tax. The preceding sentence shall
not apply to unrelated business taxable income and other
income on which Chapter 1 of the Internal Revenue Code
imposes the federal income tax or any other tax measured
by income. Note: Any corporation filing a Federal Form 990,
990-EZ, 990-N, or 990-PF should not send a copy of the
federal form or any Missouri MO-1120 Corporation Income tax
form to the Department of Revenue.

Note: When the due date falls on a Saturday, Sunday, or a legal
holiday, the return and payment will be considered timely if made
on the next business day.
If you have a refund or have no amount due, mail your return to: 
Missouri Department of Revenue, P.O. Box 700, Jefferson City, MO
65105-0700.
If you have a balance due, payments must be postmarked by April 15,
2024, to avoid interest and late payment charges. The Department of
Revenue offers several payment options. If you mail your payment
after your return is filed, attach your payment to the Form MO-1120V.

•	 An express company as defined in Chapter 153, RSMo, which
pays an annual tax on its gross receipts, in this state;
•	 An insurance company, which is subject to an annual tax on its
gross premium receipts, in this state;

•	Check or money order: Attach a check or money order (U.S.
funds only) payable to the Missouri Department of Revenue
indicating the Missouri Tax Identification Number. 

•	 A Missouri mutual or an extended Missouri mutual in­su­rance
company organized under Chapter 380, RSMo; or
•	 Any other corporation that is exempt from Missouri income taxation
under the laws of Missouri or the laws of the United States.

Mail to: Missouri Department of Revenue, P.O. Box 3365,
Jefferson City, MO 65105-3365. Do not postdate. By submitting
payment by check, you authorize the Department of Revenue to
process the check electronically upon receipt. The Department
of Revenue may electronically resubmit checks returned for
insufficient or uncol­lected funds.

Attach a copy of your Federal Form 1120. Corporations
reporting taxable income on a federal return other than a
Federal Form 1120 (such as Federal Forms 1120-POL, 1120-H,
1120-SF, 1120-REIT, 990-T, or 1120-C), shall attach a copy of the
appropriate federal form and make the computations on Form
MO-1120. A “candidate committee” set up under Section 130.011,
RSMo, who is required by the Internal Revenue Code Section
527 to file a Federal Form 1120-POL, but is not set up as a
corporation, is not required to file Form MO-1120.

•	Electronic Bank Draft (E-Check): You can pay online at
mytax.mo.gov/rptp/portal/omefileandpaybusinesstaxesonline
or by calling (888) 929-0513. You will need to enter your bank
routing number and checking account number. There will be a
$0.50 fee per filing period/transaction to use this service.

ADMINISTRATIVE DISSOLUTION

•	Credit Card: The Department accepts MasterCard, Discover,
Visa, and American Express. For online payment information

If a corporation required to file income tax fails to file and pay the
tax within 90 days from the original due date (or 90 days from the
extension due date), it shall forfeit its charter in this state under the
provisions of Section 351.486.

Note: The convenience fees charged are paid to the third party
vendor, not to the Missouri Department of Revenue. By accessing this
payment system, you will leave the Department’s website and connect
to the third party vendor’s website, which is secure and confi­dential.

*14000000001*
14000000001

attach a copy of the consolidated Federal Form 1120 for the
current tax period and the consolidated Federal 1120 for the tax
period(s) being amended on a separate company basis.

CONSOLIDATED FEDERAL RETURN
AND SEPARATE MISSOURI RETURN
A corporation, which is a member of an affiliated group filing a
consolidated federal corporation income tax return, shall (if no
Missouri consolidated return is filed) determine its federal taxable
income as if it had filed a separate federal corporation income tax
return for the year.

•	For tax periods that the consolidated return and separate
company return show an NOL that is carried back, attach a
copy of the consolidated Federal Form 1139 or Federal Form
1120X. Also include the income statement for the loss year, the
revised income statement for the amended tax period(s), and a
schedule showing the calculation of the federal income tax
de­duc­tion on the amended return.

The corporation must enclose a pro forma Federal Form 1120, with
all pertinent schedules, where­in its separate federal taxable income is
computed with Form MO-1120. The first five pages of the actual
consolidated federal corporation income tax return and an income
statement, or a summary of profit com­panies for the year, must be
attached. The complete consolidated federal return may be required
upon an audit of the Mis­souri return.

Note: The corporation is required to file an amended return to adjust
the federal income tax deduction for any tax period that the
consolidated tax liability changes due to an NOL carryback, even if no
loss exists to be carried back on a separate company basis.

REPORTABLE TRANSACTION DISCLOSURE
STATEMENT FEDERAL FORM 8886

Attach supporting statements for each corporation included in
the consolidated return. Do not use Form MO-1120 as a supporting
statement.

Every corporation must attach a copy of each Federal Form 8886 that
was filed with the IRS as part of its federal return or as part of a
consolidated federal return.

The corporation’s federal income tax de­duc­tion will be a portion of
the tax on consolidated Federal Form 1120. See Form MO-1120, Part 3.

SUBSIDIARIES INCLUDED IN THE FILING OF THIS RETURN

UNCERTAIN TAX POSITION STATEMENT
FEDERAL SCHEDULE UTP

If the corporation is filing a consolidated Missouri return, attach a
separate schedule that lists the names of the subsidiaries, Federal
Identification Numbers and Mis­souri Tax Identification Numbers.

A corporation must attach a copy of Federal Schedule UTP if the
corporation has one or more tax positions that must be reported to
the IRS on Schedule UTP and the schedule was filed with the IRS as
part of its federal return or as part of a consolidated federal return.

NET OPERATING LOSSES
Corporations that file a Missouri return with a federal net operating
loss (NOL) must treat the loss under the provisions of the Internal
Revenue Code. Corporations that file a consolidated federal and
separate Missouri return must compute the separate federal taxable
income as if each member filed a separate federal return. In any year
an NOL is carried forward or carried back, a corporation is required
to provide a schedule detailing each NOL: the year of the loss, the
amount of the loss, the loss previously utilized and the amount of
the loss currently being utilized on a consolidated and separate
company basis.

DECLARATION OF ESTIMATED TAX
Every corporation subject to income tax in this state must make a
declaration of its estimated tax for the taxable year on
Form MO-1120ES, if its Missouri estimated tax could reasonably be
ex­pected to be at least $250 (Section 143.521, RSMo).
If an affiliated group of corporations files a Missouri consolidated
income tax return for the taxable year, its Missouri estimated
tax payments may be combined on Form MO-1120
(12 CSR 10-2.045(36)).

For federal and Missouri purposes, a corporation can use the federal
NOL incurred in one tax year to reduce the taxable income in another
tax year. The NOL deduction cannot exceed the corporation’s taxable
income (after special deductions). An NOL deduction cannot be used
to increase a loss in a loss year or to create a loss in a profit year.

A corporation may amend its declaration on Form MO-1120ES.
Mail the declaration of estimated tax payments to:
Missouri Department of Rev­e­nue, P.O. Box 3020, Jefferson City,
MO 65105-3020. Make the check payable to Missouri Department of
Revenue and include your Missouri Tax Identification Number
on your check.

A separate company is bound by the consolidated federal return
election to carry losses forward or back, (i.e., if the loss is carried back
on your federal return, the separate company loss must be carried
back). If the loss is carried forward the corporation must provide
detailed schedules reflecting the loss amount(s), year(s) of the loss,
and year and amount of the loss utilized on a consolidated and
separate company basis.

You can file and pay Declaration of Estimated Tax for Corporation
Income Tax (Form MO-1120ES), online using a Credit Card or E-Check
(Electronic Bank Draft). To file and pay online, please visit
dor.mo.gov/business/payonline.php.

EXTENSION OF TIME TO FILE AND PAY

If the consolidated return shows taxable income and the separate
company return shows a loss, the corporation may elect to carry the
federal separate company loss forward or back pursuant to the
Internal Revenue Code on a separate company basis in Missouri.
The corporation must provide a copy of page 1 of the federal
consolidated return for the separate company loss year.

If a corporation has been granted an extension of time to file its
federal income tax return, the time for filing the Missouri corporation
income tax return is automatically extended. Select the box at the top
of the form indicating you have an approved federal extension and
attach a copy of the Federal Extension, Form 7004, to the MO-1120.
(Failure to check this box may result in disallowing the extension.)

The only NOL subject to carry forward or carry back is the loss from
the federal tax return. Missouri does not have provisions for a state
NOL deduction. A negative number on Form MO-1120, Lines 8, 9, or 13
is not an NOL.

An extension of time to file does not extend the time for payment of
the tax. The corporation must pay, on or before the original due date,
the amount properly estimated. If you expect to owe tax, file
Form MO-7004.

If the corporation is required to file an amended Missouri return to
carry back a federal NOL, provide the following information with the
amended Form MO-1120:

FILING AMENDED RETURNS

•	If the consolidated federal income is positive and you are
carrying back a separate company loss, attach a copy of
the consolidated Federal Form 1120 page 1 for the separate
company loss year to confirm that there is no consolidated loss
to be carried back.

Form MO-1120 must be used for amending tax year 2015 and forward
for corporation income tax. The corporation must complete the entire
return using the corrected figures. Complete each line using the
corrected amounts. Failure to fill out the entire return will delay the
processing of the return.

•	If the consolidated federal return is a loss for the current
tax period and the previous tax periods are consolidated losses,

must be attached.

A separate Form MO-1120 must be filed for each amendment reason.
If there is more than one loss year carryback, a separate Form
MO-1120 must be filed for each loss year. For example, if you have
an IRS audit or federal correction that in­cludes a Net Operating Loss,
one amended return must be filed for the federal audit and a separate
amended return must be filed for the NOL.

GENERAL INSTRUCTIONS
Complete the Form MO-MS if taxable corporation income is not 100
percent from Missouri sources. This form must be completed even if
Missouri taxable corporation income is zero. If the corporation owns a
percentage of a partnership(s), the partnership factors must be
multiplied by the corporation’s percentage of ownership, and then
added into the corporation’s apportionment factors. All taxpayers that
do not qualify for a Special Method (Methods Three through Seven)
must choose Method Two A - Receipts Factor Apportionment.

The amended return must contain a complete explanation of the
reason(s) for filing the claim or amendment. You must attach any
required schedules or forms to support your claim. If the amended
return is submitted without the proper attachments it may be partially
or totally denied.

APPORTIONMENT ELECTION
Missouri statutes provide a number of methods for determining
Missouri taxable income from Missouri sources. Choose only the
appropriate one of the listed methods and enter the method number
on Form MO-1120, Line 9 Method. Once an election has been made, it
cannot be changed with respect to the same taxable period.

Part 5 - Amended Return Loss Carryback or

would include an NOL, capital loss, or product liability loss. A loss
carryback is required to be filed by the 15th day of the 39th month
following the end of the loss year (Section 143.801.6, RSMo). Lines
2 and 3 should reflect the total net operating loss or capital loss
carryback.

METHOD TWO A
Receipts Factor Apportionment — Section 143.455.2, RSMo. See
instructions for completing Method Two A.

Line 4 should reflect the difference between the original and amended

separate Form MO-1120 must be filed for each loss year carryback.

METHOD THREE
Transportation — Section 143.455.14, RSMo.

Note: Missouri does not allow an NOL to be carried back more than
two years; the amount of an NOL carried back more than two years
results in an addition modification for the carryback year. (Section
143.121.2(4), RSMo). An NOL disallowed (added back) on this basis
may be carried forward for 20 years from the loss year. See Form
MO-1120, Part 2, Line 9.

METHOD FOUR
Railroad — Section 143.455.15, RSMo.

nonapportionable income. The taxpayer’s income will be allocated
and apportioned according to Section 143.455. The taxpayer must
determine which portion of the taxpayer’s federal taxable income
constitutes “nonapportionable income.” The various items of
nonapportionable income are directly allocated to specific states,
which may include Missouri. The apportionable income of the taxpayer
is divided between states by using the receipts factor. The sum of
the items of nonapportionable income directly allocated to this state,
plus the amount of apportionable income attributable to this state by
the apportionment formula constitutes the amount of the taxpayer’s
Preliminary Missouri taxable income.

The Department of Revenue strives to assist taxpayers in their
inquiries; however, the Department of Revenue is bound by
confidentiality statutes dealing with the release of confidential
information. If you are contacting the Department of Revenue
regarding financial information of a corporation, refund issuance,
or filing status of a corporation, you will be asked to identify your
position with the corporation. If you are an officer of the corporation,
an authorized individual having power of attorney, the preparer
or any member of their firm, or if internally prepared, any member
of the internal staff, the authorization box on the form must have
been checked for the Department of Revenue to release financial
information. To prevent delays in answering questions, you must
provide the Department of Revenue with a Form 2827, Power of
Attorney, prior to making the inquiry. This also applies to employees
of the corporation. This form must list the tax type, the tax form, and
tax year(s) in question. These procedures are to protect the taxpayer
from unauthorized disclosure of financial records. To update corporate
officers, send Form 126 : Taxation Division, P.O. Box 3300, Jefferson
City, MO 65105-3300 or email at [email protected].

Items of nonapportionable income may be reported on Form MO-MS
or Form MO-NAI only to the extent such items are included in Form
MO-1120, Line 8 (Taxable Income – All Sources). For example, an item
of nonapportionable income that was added on Form MO-1120, Line
3, would also be reported on Form MO-MS and Form MO-NAI. If all
or part of an item of nonapportionable income was subtracted on
Form MO-1120, Line 5, do not report the amount of nonapportionable
income so subtracted on Form MO-MS or Form MO-NAI.

in Missouri by the purchaser. Receipts from the rental, lease,
or license of tangible personal property are in this state to the
extent that the tangible personal property is located in Missouri.

APPORTIONABLE AND NONAPPORTIONABLE
INCOME DEFINED

•	Real Property. Receipts from the sale, rental, lease, or license
of real property are in this state to the extent that the real
property is located in Missouri.

“Apportionable income” means all income that is apportionable
under the Constitution of the United States and is not allocated
under the laws of this state. Apportionable income includes, but
is not limited to, income arising from transactions and activity
in the regular course of the corporation’s trade or business.
Apportionable income also includes, but is not limited to, income
arising from tangible and intangible property if the acquisition,
management, employment, development, or disposition of the
property is or was related to the operation of the corporation’s
trade or business. “Nonapportionable income” means all income
other than apportionable income. The classification of income by
the labels customarily given them, such as interest, dividends, rents,
and royalties, is not conclusive in determining whether the income
is apportionable or nonapportionable income. Nonapportionable
income will be considered only if a detailed Form MO-NAI is
completed and attached.

•	Services. Receipts from the sale of a service are in this state if
and to the extent that the ultimate beneficiary is in Missouri.
Generally, the ultimate beneficiary of the service (except for
bartering and similar in-kind transactions) is the entity that
receives benefit or value from, but does not also receive
monetary or credit-based payment in direct connection with,
the service at issue (other than refunds, cashback, or discountequivalents). In the event that the ultimate beneficiary is a
corporate or other entity that owns or operates in locations in
multiple states, and the extent to which the ultimate beneficiary
is located in Missouri cannot reasonably be determined, the
extent to which the ultimate beneficiary is located in Missouri
may be reasonably approximated as follows:
•	The ratio of the number of Missouri locations, which the 	
ultimate beneficiary owns or operates in, to the number of 	
such locations throughout the United States.

TAXABLE IN ANOTHER STATE

•	If the ratio above cannot reasonably be determined, then the 	
ratio of one to the number of states in which the ultimate 		
beneficiary operates.

A taxpayer is “taxable in another state” if it meets either one of two
tests:
(a) if by reason of business activity in another state the taxpayer
is subject to one of these taxes: a net income tax, a franchise tax
measured by net income, a franchise tax for the privilege of doing
business, or a corporate stock tax; or

•	If the ratio above cannot reasonably be determined, then use
fifty percent (50%). A taxpayer will not be subject to an addition
to tax for negligence in relying upon this approximation of fifty
percent (50%).

(b) if another state has jurisdiction to subject the taxpayer to a net
income tax, regardless of whether or not that state imposes such a
tax on the taxpayer.

RENTAL, LEASE, OR LICENSE
OF INTANGIBLE PROPERTY
Receipts from the rental, lease, or license of intangible property
are in this state to the extent that the intangible property is used in
Missouri. Intangible property that is rented, leased, or licensed and
then used in this state in marketing a good or service to a consumer
is used in this state if the marketed good or service is purchased by a
consumer in this state. Franchise fees or franchise royalties received
for the rent, lease, license, or use of a trade name, trademark, service
mark, or franchise system, or the right to conduct business activity in
a specific geographic area, are receipts in this state to the extent that
the franchise is located in this state.

The first test is applicable only if a taxpayer carries on business
activities in another state. If the taxpayer voluntarily files and pays
one or more of such taxes when not required to do so by the laws
of that state or pays a minimal fee for qualification, organization, or
for the privilege of doing business in that state, but:
(a) does not actually engage in business activities in that state; or
(b) does actually engage in some activity, not sufficient for nexus,
and the minimum tax bears no relation to the corporation’s
activities within such state, the taxpayer is not “taxable” in another
state.

SALE OF INTANGIBLE PROPERTY

The second test applies if the taxpayer’s business activities are
sufficient to give the state jurisdiction to impose a net income
tax under the Constitution and statutes of the United States.
Jurisdiction to tax is not present where the state is prohibited
from imposing the tax by reason of the provisions of Public Law
86-272, 15 U.S.C.A. Sections 381–385. If you believe you do not
have sufficient nexus and you are not liable for Missouri tax, you
may complete a Form 4458, Business Activity Questionnaire. For
Missouri forms access the Department of Revenue’s website at dor.
mo.gov.

Receipts from the sale of intangible property are in this state to the
extent the intangible property is used in Missouri. If the
intangible property sold is a contract right, government license, or
similar property that authorizes the holder to conduct a business
activity in a specific geographic area, such intangible property is used
in Missouri if the geographic area include
