Maryland State Tax Extensions: Business, Personal, Information and Nonprofit Tax Returns

Maryland law provides for an extension of time to file the corporation income tax return (Form 500), but not to pay the tax due. Use Form 500E to remit any tax that may be due. Also use Form 500E if this is the first filing of the corporation even if no tax is due.

Purpose of Form

Form 500E is used by a corporation to request an extension of time to file the corporation income tax return (Form 500) and to remit any balance of tax due.

NOTE: Do not use this form for pass-through entities (including S corporations) or to remit employer withholding tax.

General Requirements

Maryland law provides for an extension of time to file, but in no case can an extension be granted for more than six months beyond the original due date. A request for extension of time to file will be automatically granted for six months, provided that:

• Form 500E is properly filed and submitted by the original due date (15th day of the 3rd month following close of the tax year or period, or by the original due date required for filing of the federal return);
• full payment of any balance due is submitted with Form 500E; and
• an application for extension of time has been filed with the Internal Revenue Service or an acceptable reason has been provided with Form 500E.

A proper application for extension of time to file will not be acknowledged. If the extension request is denied, the corporation will be notified.

Where to File?

If line5 is zero, you may request an automatic extension by calling 410-260-7829 from Central Maryland or 1-800-260-3664 from elsewhere to telefile this form. Please have the form in front of you when you call this number. The application for extension of time must be filed with the

Comptroller of Maryland,
Revenue Administration Division,
Annapolis,
Maryland 21411-0001.

When to file?

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

Who must file Form 502E?

If you cannot complete and file your Form 502, 503, 505 or 515 by the due date, you should complete the Tax Payment Worksheet to determine if you must file Form 502E. If line 6 of the worksheet shows you owe tax, you must file this form and pay the full amount due by April 15, 2025, (or the fifteenth day of the fourth month following the close of the tax year). If the due date falls on a Saturday, Sunday or legal holiday, the return must be filed by the next business day.

NOTE: Filing an extension does not extend the time for paying your taxes.

Do not file Form 502E:

if, after completing the Tax Payment Worksheet, you find that you do not owe additional tax. However, please be aware that if an unpaid liability is disclosed when you file your return, you may owe penalty and interest charges in addition to the tax. See "Will I owe penalties and interest?" in the column to the right.

Automatic Maryland six-month extension

If you filed a federal extension and expect to owe zero tax to Maryland we grant you an automatic six-month extension of time to file your Form 502, 503, 505 or 515. You are not required to file Form 502E in order to obtain this automatic extension. However, you should use Form 502E to pay any tax due in order to avoid any late-payment penalty and interest on tax not paid by April 15, 2025.

Should I attach a copy of the extension form to my Form 502, 503, 505 or 515?

You do not have to attach anything to your return relating to your extension.

When requesting an extension beyond six months, how should I file?

No extension request will be granted for more than six months, except in the case of individuals who are out of the United States. Even when an individual is out of the U.S. an extension will not be granted for more than one year. An extension request for beyond six months without a payment should be filed by telefile or on our Web site

Will I owe penalties and interest?

You will owe interest on tax not paid by the regular due date of your return. The interest will accrue until you pay the tax. Even if you had a good reason for not paying on time, you will still owe interest. If tax and interest are not paid promptly, a penalty will be assessed on the tax.
