RETURN INSTRUCTIONS

GENERAL INSTRUCTIONS

•	 Nonprofit organizations that are exempt from taxation
under IRC Section 501, except those with taxable income for
federal purposes, such as unrelated business taxable income
or exempt function income under IRC Section 527.

FILING FORM 500
Form 500 must be filed electronically if the corporation plans
to claim a business income tax credit from Form 500CR or the
Maryland Historic Revitalization Tax Credit from Form 502S.

	 Under Section 501, a variety of organizations, generally
nonprofit groups organized for charitable or mutual benefit
purposes, are exempt from income taxation. However, it may
be subject to income tax if it has income from the operation of
a business not related to the purpose for which they received
their exemption.

PURPOSE OF FORM Form 500 is used by a corporation and
certain other organizations to file or to amend an income tax
return for a specific tax year or period.
NOTE: S corporations must use Form 510 — Maryland PassThrough Entity Income Tax Return, or Form 511 - Pass-Through
Entity Election Income Tax Return.

1

	 The same tax treatment afforded for federal income tax
purposes is afforded for Maryland income tax purposes.
Income that is taxable for federal purposes also is taxable for
Maryland purposes. Exempt corporations with federal taxable
income must file Form 500 to report the income and pay the
tax.

WHO MUST FILE?

TAXPAYERS REQUIRED TO FILE Every Maryland corporation
must file an income tax return on Form 500, even if it has no
taxable income or if the corporation is inactive. Every other
corporation that is subject to Maryland income tax law and has
income or losses attributable to sources within Maryland also
must file Form 500.

	 Whether or not required to file Form 500, nonprofit
organizations operating in Maryland that are subject to federal
exempt-status notification requirements must register with
the Maryland Revenue Administration Division. To register, an
authorized official must submit a letter of request accompanied
by a copy of the Internal Revenue Service (IRS) determination
of tax-exempt status.

Corporations operating in Maryland and in one or more other
states are subject to Maryland income tax if their Maryland activity
exceeds the provisions for federal protection from state taxation.
U.S.C.A. Title 15, Section 381 of the Interstate Commerce Tax
Act (P.L. 86-272) prescribes the extent of business activity
required before states may impose income taxes.

	 Other agencies such as the State Executive Department Secretary of State, State Department of Assessments and
Taxation and Attorney General’s Office each has its own
specific requirements for nonprofit organizations.
•	Investment conduits such as a Regulated Investment
Company (RIC), and a Real Estate Mortgage Investment
Conduit (REMIC), except those with taxable income for federal
purposes. Investment conduits with such taxable income
must file Form 500 reporting the taxable income. Real Estate
Investment Trust should see Special Requirements For Certain
Organizations.

A multistate corporation that operates in Maryland but is not
subject to the Maryland income tax law is not required to file,
although a return reflecting an apportionment factor of zero may
be filed for record purposes. Letters in lieu of filing will not be
accepted.
All financial institutions are subject to corporation income tax
and have special apportionment rules. See Code of Maryland
Regulations (COMAR) Chapter 03.04.08.

•	Individual retirement account (IRA) trusts that are
exempt from taxation under IRC Section 408 (e)(1), except
those with taxable income for federal purposes. IRA trusts
with such taxable income must file Form 504 reporting the
taxable income.

ORGANIZATIONS EXEMPT FROM FILING The following
organizations are not subject to the Maryland corporation income
tax and are exempt from filing an income tax return on Form
500, except as specified:
•	 Pass-through entities defined as partnerships in IRC
Section 761, S corporations in IRC Sections 1361 and 1362,
Limited Liability Companies (LLC) in Maryland Corporations
and Associations Article Section 4A-101 and business trusts in
Maryland Corporation and Associations Article Section 12-101.

•	Insurance companies within the meaning of the Insurance
Article, Annotated Code of Maryland, Managed Care
Organizations and Health Maintenance Organizations are
subject to the insurance company premium tax. Insurance
companies must contact the Maryland Insurance Administration
regarding filing requirements and taxation.

	 LLCs and Business Trusts are treated as partnerships for
Maryland income tax purposes, unless they are treated as
corporations for federal income tax purposes.

•	Common trust funds as defined in the Maryland Financial
Institutions Article Section 3-501(b).
•	Fiduciary taxpayers must file an income tax return on Form
504. Fiduciaries who are an Electing Small Business Trust
(ESBT) are taxable by Maryland. See Form 504 Instructions
for more information.

	 Pass-through entities must file an income tax return on Form
510 or Form 511. Additionally, each member must file an
income tax return.
	 An S corporation that is subject to federal income tax at the
corporate level, also is subject to Maryland corporation income
tax and Form 500 must be filed.

SPECIAL REQUIREMENTS FOR CERTAIN ORGANIZATIONS
•	Affiliated corporations that file consolidated federal
returns must file separate Maryland returns for each member
corporation. Each member corporation must file and report
the taxable income or loss on a separate basis, without
regard to the consolidation for federal income tax purposes.
Consolidation adjustments reported for federal purposes are
not allowed for Maryland purposes.

	 Maryland will follow the IRS rules for a single member LLC
that is disregarded as a separate entity (“check-the-box”) and
certain partnerships that do not actively conduct a business
and have elected not to be treated as a partnership.
	 For additional information regarding the taxation and filing
requirements of pass-through entities, see the instructions
provided with Form 510 and Form 511.

•	Qualified Sub-S Subsidiaries are treated as divisions by the
IRC and are not considered as separate entities for Maryland
purposes. These divisions will be included on the parent

WHEN AND WHERE TO FILE

GENERAL INFORMATION FOR FORM 500

Accounting Periods The tax year or period used for the federal
return must be used for the Maryland return. Accordingly,
calendar tax years, fiscal tax years, 52-53 week tax years, and
short tax periods may be necessary for Maryland filing purposes.

File the original Form 500 by the 15th day of the 4th month
following the close of the tax year or period, or by the original
due date required for filing the federal return.

A Maryland return must be filed for each reporting period for
which a federal return is filed or required. The form used for filing

Generally, a claim for a refund or overpayment credit must be

carryback year.

must reflect the preprinted tax year in which the corporation’s
tax year begins.

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.

In a 52-53 week tax year, Maryland follows federal treatment as
to effective dates or the applicability of any provision expressed in
terms of tax years beginning, including or ending with reference
to a specified date.
Use of Federal Figures In preparing Form 500, all items
reported for federal purposes must be reported on the Maryland
return in the same manner. The character of an item cannot be
changed from that required or elected for federal purposes.

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).

Copy of Federal Return Required A copy of the actual federal
income tax return through Schedule M2 as filed with the IRS for
the corresponding tax period must be attached to Form 500. The
Maryland filing will not be complete unless the required federal
copy is attached.

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.

Corporations included in a consolidated filing for federal income
tax purposes must file separate returns for Maryland purposes
and attach a copy of the actual consolidated federal return
through Schedule M2 to each Maryland filing. Each Maryland
filing also must include a copy of the columnar schedules of
income and expense and of balance sheet items (which are
required for the federal filing), reconciling the separate items of
each member corporation to the consolidated totals.

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.
The federal special deduction for dividends is treated as
a current year deduction. It is deducted from federal taxable
income before application of the net operating loss deduction.
The deduction reduces taxable income and may create a net
operating loss.

Taxable Income The starting point for Form 500 is taxable
income as developed for the federal income tax return after
special deductions for dividends. (See “Specific Instructions” for
line 1a and 1b.) No modification of the federal net operating
loss or special deductions is allowed under Maryland income
tax law except in the case of a Foreign Dividend Subtraction
Carryforward (FDSC), decoupling modifications, and Section 10306.1 related party transactions.

If an affiliated group of corporations files a consolidated
return for federal purposes, each member corporation must
calculate any net operating loss and special deductions based
on its separate federal taxable income and loss. The deductions
must be calculated in strict accordance with federal income tax
provisions, as if the member corporation is not involved in a
consolidated filing and files a separate return with the IRS.

The federal net operating loss deduction effectively is allowed
for the Maryland filing by using federal taxable income. The
federal provisions for carryback and carryforward also apply
for purposes of the Maryland return unless you are following
certain provisions of the Job Creation, Worker Assistance Act of
2002, the American Recovery and Reinvestment Act of 2009. 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.

Maryland modified income is federal taxable income
after statutory addition and subtraction adjustments and/or
modifications. For a list of the statutory addition and subtraction
adjustments and modifications, see Specific Instructions.
Maryland apportioned income is applicable only for multistate
corporations and is developed by applying the apportionment
factor to Maryland modified income. For an explanation of
apportionment provisions, see Instructions for Schedule A –
Computation of Apportionment Factor.

For the tax year in which a net operating loss occurs, that
current operating loss is used to offset Maryland modifications.
If the total of addition modifications exceeds the total
subtraction modifications in the tax year of the net operating
loss, a modification to recapture the excess of additions over
subtractions is required when claiming the corresponding net
operating loss deduction. For more information, see Section 10205 of the Maryland Tax-General Article.

Maryland taxable income is federal taxable income
after statutory adjustments, modifications, and applicable
apportionment.
Maryland Business Income Tax Credits For information
about credits against the tax, see Specific Instructions for lines
15c and 15d or the instructions provided for Form 500CR Maryland Business Income Tax Credits. Form 500CR Instructions
are available online at marylandtaxes.gov. You must file Form
500CR electronically to claim a business income tax credit.

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.

Tax, Interest and Penalty The tax rate is 8.25%. The annual
rate of interest charged for taxes owed to the State is 10.0075%
from 01/01/24 through 12/31/24. The annual interest rate
after 12/31/24 is 11.4825%. For more information, visit
marylandtaxes.gov.

A corporation included in a consolidated federal filing must use
its separate federal NOL. An NOL should be entered on line 5 on
Form 500 but may not be used to reduce line 6 to less than zero.
Note: For 2020, Maryland has decoupled certain provisions
from the CARES Act. For more information, see Tax Alert
7-24 at marylandtaxes.gov.

A penalty is applicable for late filing of tax returns and/or late
payment of any taxes due. Additional penalties are applicable for
the filing of false, fraudulent or frivolous returns and civil and/or
criminal fines and imprisonment may apply.

Generally, the carryback of an NOL does not change the
previously reported addition or subtraction modifications in a

the assessment or denial of the refund.

In the case of delinquent taxes, the State will record a lien and
judgment and proceed with legal action as necessary to effect
collection of the balance due.

5

Failure to file a written request or attend the informal hearing
will result in the assessment or denial of refund becoming final
and non-appealable.

OTHER MATTERS

You may file an appeal with the Maryland Tax Court within 30
days of a final determination by the Compliance Division hearing
officer.

Extension of Time to File If unable to file Form 500 by the
due date, a corporation must submit Form 500E - Maryland
Application for Extension to File Corporation Income Tax Return.
Maryland law provides for an extension of time to file, but in no
case can an extension be granted for more than seven months
beyond the original due date.

Amended Return Form 500X has been combined with
Form 500. To correct an error in previously filed returns, check
the amended return box on page 1 and complete the entire
return (where applicable) including the amended figures. Attach
copies of the documents required and filed with the IRS. If the
corrections affect only the Maryland return and not items of
federal taxable income, include a thorough explanation of the
changes.

The request for extension of time to file will be granted for seven
months, provided that:
1) The application is properly filed and submitted by the 15th
day of the 4th month following the close of the tax year or
period, or by the original due date required for filing of the
federal return; and

Each affected member of a consolidated federal filing also must
include a schedule reconciling the amendments of each member
corporation to the consolidated totals.

2)	Full payment of any balance due is submitted with the
application.

Federal income tax law provides for certain capital loss carryback
and carryforward. Any carryforward effectively is allowed when
reporting federal taxable income on the Maryland return.
Except as specifically decoupled from the CARES Act. For more
information, see Tax Alert 7-24 at marylandtaxes.gov. Do not
attach amended returns to an original corporation income tax
filing.

The application extends only the time allowed to file the annual
income tax return and not the time allowed to pay the tax.
For additional information regarding extensions of time to file,
see the instructions provided with Form 500E.
Estimated Income Tax Every corporation that reasonably
expects its Maryland taxable income to develop a tax in excess
of $1,000 for the tax year or period must make estimated
income tax payments with Form 500D - Maryland Declaration
of Estimated Corporation Income Tax. If the corporation is
required to make multiple payments it will use a Form 500D
for each of the additional payments. This form is available at
marylandtaxes.gov.

Amended return(s) must be filed electronically if the change is
related to a business income tax credit from Form 500CR.
NOTE: Changes made as part of an amended return are subject
to audit for up to three years from the date that the amended
return is filed.
Federal Adjustments If the items of federal taxable income
reported for any tax year or period are adjusted by the IRS
and will increase Maryland taxable income, an amended return
together with a copy of the final IRS adjustment report must be
submitted within 90 days.

Declaration of estimated income tax payments are due by the
15th day of the 4th, 6th, 9th and 12th months following the
beginning of the tax year or period. The total estimated tax
payments for the year must be at least 90% of the tax developed
for the current tax year or 110% of the tax that was developed
for the prior tax year. At least 25% of the total estimated tax
must be remitted by each of the four installment due dates.

Each affected member of a consolidated federal filing also must
include a schedule reconciling the separate adjustments of each
member corporation to the consolidated totals.
Refund Claims Generally, a claim for a refund (amended
return) must be filed within 3 years from the date the original
return was filed or within 2 years from the date the tax was paid,
whichever is later. A return filed early is considered filed on the
date it was due.

In the case of a short tax period, the total estimated tax required
is the same as for a regular tax year: 90% of the tax developed
for the current (short) tax year or 110% of the tax that was
developed for the prior tax year. The minimum estimated tax
for each of the installment due dates is the total estimated
tax required divided by the number of installment due dates
occurring during the short tax year.

If the claim for refund resulted from an IRS adjustment or final
decision of a federal court which is more than 3 years from the
date of filing the return or more than 2 years from the time the
tax was paid, a claim for refund must be filed within 1 year from
the date of the adjustment or final decision.

For additional information regarding estimated income tax, see
the instructions provided with Form 500D.
Audits and Appeals All items reported on Form 500 are subject
to audit, verification and revision, including items reported for
federal purposes. Returns and amendments are subject to audit
and adjustment for a period of 3 years from the date the return
was due (including extensions) or the date the return was filed,
whichever is later.

A claim for refund based on a federal net operating loss carryback
must be filed within 3 years after the due date of the return for
the tax year of the net operating loss.
Taxpayer Identification Required for Returns and Other
Documents All returns, correspondence, payments or other
documents must indicate the corporation name, Federal
Employer Identification Number (FEIN), type of tax and tax
year(s) to which the document relates.

In the event of revision and assessment or reduced refund, the
Comptroller will notify the corporation. If in disagreement with
the assessment or denial of the refund, the corporation may file
with the Compliance Division a written request for revision of the
assessment or reconsideration of the refund denial. The request,
in either case, must be made by submitting an application for an
informal hearing with the Compliance Division within 30 days of

All corporations are required to secure a FEIN from the IRS. The
FEIN is the number used by the IRS for processing purposes
and also is the primary number used by the Maryland Revenue
Administration Division.
