AMENDED CORPORATION INCOME
TAX RETURN INSTRUCTIONS
For tax years beginning 2019

PURPOSE OF FORM. You must file your Maryland Amended Form
500X electronically to claim, or change information related to,
business income tax credits from Form 500CR (including Maryland
Form 502S, Heritage Structure Rehabilitation Tax Credit.)
Form 500X is used by a corporation to correct an error in a
previously filed 2019 return (Form 500- Corporation Income Tax
Return) or to claim a net operating loss (NOL) deduction.
Form 500X may not be used to correct the amount of payments.
To correct payment amounts, submit a letter of request that
indicates the corporate name, Federal Employer Identification
Number (FEIN), type of tax and tax year beginning and ending
dates. Explain the basis for the request and attach copies of
canceled checks and/or other documents as necessary to verify the
amounts claimed.
WHEN AND WHERE TO FILE. Generally, Form 500X must be filed
within 3 years from the date the original return was due or filed. A
return filed before the due date is considered to have been filed on
the date it was due. The following exceptions apply:
•

A claim for refund filed within 3 years after the date of filing the
return is limited to the amount paid within the 3 years
(including extensions) before you filed the claim.

•

A claim for refund filed after 3 years, but within 2 years from
the date the tax was paid is limited to the amount paid within
the 2 years immediately before filing the claim.

•

A claim for refund based on a federal NOL carryback must be
filed within 3 years after the due date (including extensions) of
the return for the tax year of the NOL.

•

If the Internal Revenue Service (IRS) issues a final
determination of adjustments that would result in an increase to
Maryland taxable income, file Form 500X within 90 days after
the final determination.

•

If the IRS issues a final report of adjustments that would result
in a decrease to Maryland taxable income, file Form 500X within
1 year after the final adjustment report or the final court
decision, if appealed.

•

If the claim for refund or credit for overpayment resulted from a
final determination made by an administrative board or an
appeal of a decision of an administrative board, that is more
than 3 years from the date of filing the return or more than 2
years from the time the tax was paid, the claim for refund must
be filed within 1 year of the date of the final decision of the
administrative board or final decision of the highest court to
which an appeal of the administrative board is taken.

Note: Changes made as part of an amended return are subject to
audit for up to three years from the date the amended return is
filed. For more information regarding refund limitations, see
Administrative Release 20.
The amended return must be filed with the:
Comptroller of Maryland
Revenue Administration Division
110 Carroll Street
Annapolis, MD 21411-0001
INFORMATION ON INCOME TAX PROVISIONS. Refer to the
instructions for 2019 Form 500 for information regarding applicable
Maryland income tax provisions.
NET OPERATING LOSS DEDUCTIONS. The NOL for Maryland
purposes is the federal net operating loss. No modification of
the federal NOL is allowed under Maryland income tax law except
in the case of a foreign source dividend subtraction. For more
information about foreign source dividend subtractions, refer to
Administrative Release 18.

■

COM/RAD-066

2019

page 1

A corporation included in a consolidated federal filing must use its
separate federal NOL. An NOL should be entered on line 2b on
Form 500X but may not be used to reduce line 3 to less than zero.
Generally, the carryback of an NOL does not change the previously
reported addition or subtraction modifications in a carryback year.
The federal provisions for carryback and carryforward apply for
purposes of the Maryland return unless you are following certain
provisions of the Internal Revenue Code (IRC) from which the
State of Maryland has decoupled, including certain special
depreciation allowances and 2-year carryback provisions (farming
loss only). If an election to forgo a carryback is made, a copy of
the federal election must have been included with the Maryland
return for the loss year.
An addition modification may be required in a carryback or
carryforward year if the total Maryland addition modifications
exceed the total Maryland subtraction modifications in the loss
year (NAM or net operating loss modification recapture).
The required addition modification represents a recapture of the
excess additions over subtractions and generally is equal to the
lesser of the NOL deduction in the carryback year or the net
addition modification in the loss year. For more information
regarding net addition modification, refer to Administrative Release
18.
NET CAPITAL LOSSES. If a net capital loss carryback is used to
reduce federal taxable income, an addition modification is required
for the amount of the income reduction.
SPECIFIC INSTRUCTIONS
TAX YEAR OR PERIOD. The Form 500X instructions are for
corporations with tax years beginning in 2019. If the corporation
operates on a fiscal year, enter the beginning and ending dates of
the tax year being amended in the spaces provided at the top of
Form 500X.
NAME, ADDRESS AND OTHER INFORMATION. Enter the
required information in the designated area. Enter the current
name, address and FEIN on the appropriate lines. If the name and/
or address is different from that shown on the original return, enter
the name and address as shown on the original return in the
appropriate area.
Answer all of the questions and attach copies of any federal notices
or reports, amended forms and/or extensions required.
PART A – INCOME, MODIFICATIONS AND APPORTIONMENT
Complete lines 1 through 5, columns A, B and C. If the items of
federal income are amended or adjusted, determine if the changes
will affect the Maryland modifications and/or Maryland
adjustments. Enter the correct amounts. The federal NOL
carryback or carryforward amount reported on the federal return,
without regard to the decoupled provisions, is entered on line 2b.
Do not use Form 500DM line 2 to report this amount. See
Administrative Release 18.
Determine if the changes to federal taxable income will affect the
apportionment factor. If the apportionment factor needs to be
changed, complete Part C of Form 500X, then complete lines 6
through 8, columns A, B and C on page 1. Then, complete line 9,
columns A, B and C.
PART B – P A Y M E N T S , C R E D I T S , B A L A N C E D U E
OVERPAYMENT, INTEREST AND/OR PENALTY

OR

Complete lines 10a through 10f, columns A, B and C. Include as an
estimated tax payment on line 10a the income tax withheld as a
result of a non-Maryland real estate transaction as shown on Form
MW506NRS.

MARYLAND
FORM

500X

NOTE: An addition to income is required for certain credits claimed
on line 10c. Refer to the instructions for Form 500CR, Business Tax
Credits, to determine if any addition modification is required for the
credits you are claiming and follow those instructions for including
the required addition.
If you are claiming credits on line 10c, you must complete the
Form 500CR section of your electronic return. If claiming a
refundable business income tax credit, enter on line 10d and
complete the Form 500CR section of the electronic return that
pertains to refundable business tax credits.
An addition modification is required if you are a qualified small
business eligible to claim the Maryland Research and Development
Tax Credit.
To claim a Heritage Structure Rehabilitation Tax Credit, complete
the Form 502S electronically and enter the amount on line 10d. If
claiming a credit for taxes paid on behalf of the corporation by a
pass-through entity, enter on line 10e and include Maryland
Schedule K-1.
Complete lines 11 through 13b, columns A, B and C and enter any
overpayment	due	on	line	14	or	balance	due	on	line	15.		
If there is a balance due on line 15, calculate simple interest on
that amount from the due date of the original return to the date of
payment at an annual rate of 10.5% or a rate of 0.8750% per
month for any month or part of a month that a tax is paid after the
original due date of the 2019 return but before January 1, 2021.
For assistance in calculating interest for tax paid on or after
January 1, 2021, see the Comptroller’s website. If the requirement
for avoidance of interest for underpayment of estimated income
tax has not been met, you should complete Form 500UP for the tax
year being amended and attach it to your amended return. Add
the late payment interest charges and any interest and/or penalty
charges from Form 500UP and enter them on line 16.
NOTE: If you completed and attached Form 500UP with your
original return, you should attach a revised Form 500UP based on
the amended changes reported on Form 500X.
Interest and/or penalty charges for the year of the amendment,
whether previously paid or still outstanding, may be adjusted as a
result of the amended changes. Any payments made on an account
after the initial tax paid with the actual return are applied first to
penalty, then to interest and lastly to tax due. These payments
may require reallocation depending on the result of the
amendment. We will issue notification of the net balance due or
refund after we have processed the return.
NOTE: If the amount of tax due is reduced by reason of a
carryback of an NOL, such reduction shall not affect the calculation
of interest charges for the period ending with the filing date
(defined as due date) for the loss year. Any Maryland penalty
charge is not affected by an NOL carryback.
Interest is generally not paid on refunds. However, interest will be
paid	 if	 a	 claim	 for	 refund	 is	 not	 processed	 within	 45	 days	 of	 receipt	
of an amended return based on NOL carryback. In such cases,
interest	 will	 be	 paid	 only	 from	 the	 45th	 day	 after	 receipt	 by	 the	
Comptroller’s Office until the date the refund check is issued. For
more information regarding interest, refer to Administrative
Release	14.
PART C – COMPUTATION OF APPORTIONMENT FACTOR
If any changes to the apportionment factor are required due to the
amendment, complete Part C using the amended receipts, property

COM/RAD-066

For tax years beginning 2019
