Printer-friendly PDF

General information

If you have already applied for an extension of time to file your returns and you need more time, use Form CT-5.1 to request an additional three-month extension. File one Form CT-5.1 when requesting an additional three-month extension for both your tax return and MTA surcharge return. You must file a separate Form CT-5.1 for each additional three-month extension.

Limitations

• A corporation taxable under Article 9 with a valid three-month extension is limited to three additional three-month extensions.
• A corporation taxable under Article 9-A, 13, or 33 with a valid six-month extension is limited to two additional three-month extensions.
• New York S corporations may not request an additional extension of time beyond six months.

Combined groups

The parent or designated agent of a new, or existing, combined group should file one Form CT-5.1 to request an additional three-month extension of time to file for all corporations included in the combined group.

Exceptions

• Each taxpayer member corporation of a new combined group must also file a separate Form CT-5.1 to additionally extend the time to file for the first period for which the new combined group files a combined return. Mark an X in the box on line B.
• Each taxpayer member corporation being newly added to an existing combined group must also file a separate Form CT-5.1 to additionally extend the time to file for the first period for which they are included in the combined group’s return. Mark an X in the box on line C.

Note: Non-taxpayer members of a combined group are not required to file a separate Form CT-5.1, whether they are included on Form CT-5.3, Request for Six-Month Extension to File (for combined franchise tax return, or combined MTA surcharge return, or both), or not.

Neither filing, nor the failure to file, a particular extension request in any way impacts who must be included in a combined group.

When to file

File Form CT-5.1 on or before the expiration date of your current extension.
