Requirements for a valid New York State extension

Most corporation taxpayers are required to file their extensions electronically. See Tax documents that must be e-filed or visit www.tax.ny.gov (search: mandate).
You must file Form CT-5 and pay the properly estimated franchise tax and metropolitan transportation business tax (MTA surcharge) on or before the original due date of the tax return for which you are requesting an extension, as determined on Worksheet for lines 1 and 6 in these instructions.
The properly estimated franchise tax and MTA surcharge must either:
- equal or exceed the franchise tax and MTA surcharge shown on your tax return for the preceding tax year (if it was a 12-month tax year); or
- equal or exceed 90% of the franchise tax and MTA surcharge as finally determined for the tax year for which you are requesting this extension.

The preceding tax year is the tax year immediately before the tax year for which you are requesting this extension.

The franchise tax is the amount of tax calculated after you deduct any tax credits and before you add the MTA surcharge.

You must adjust the franchise tax and MTA surcharge for the preceding tax year as needed to correct any errors in calculation or in the application of the tax rate or tax base.

How to choose the correct extension form

Corporations subject to tax under Tax Law Articles 9-A, 13, and 33

You may file Form CT-5 to request a six-month extension of time to file the appropriate tax return and MTA surcharge return.

To request an extension of time to file both the franchise tax and MTA surcharge returns:

Use lines 1 through 5 to calculate the estimated franchise tax.
Use lines 6 through 10 to calculate the estimated MTA surcharge.
Submit only one Form CT-5. Do not submit separate forms for each return.
Submit only one payment of the combined amount for both franchise tax and MTA surcharge.

Corporations filing a combined franchise tax return only (Form CT-3-A or CT-33-A)

For combined filers to request a six-month extension of time to file, they must use Form CT-5.3, Request for Six-Month Extension to File (for combined franchise tax return, or combined MTA surcharge return, or both).

The designated agent (Article 9-A), or parent (Article 33), of a new or existing combined group will file one Form CT-5.3 to request a six-month extension of time to file for all corporations included in the combined group.

However, the following taxpayer member corporations must also file a separate Form CT-5:

Each taxpayer member corporation of a new combined group must file a separate Form CT-5 to extend the time to file for the first period for which the new combined group files a combined return:
- On Form CT-5, under Certain corporations filing as part of a combined group, line B, enter the employer identification number (EIN) of the designated agent (Article 9-A), or parent (Article 33).
- On line C, mark an X in the box.
- Do not complete line A, line D, or lines 1 through 16.
- Complete your business information and file by the original due date of the combined return (see Where to file).

Each taxpayer member corporation being newly added to an existing combined group must also file a separate Form CT-5 to extend the time to file the return for the first period for which they are included in the combined group’s return:
- On Form CT-5, under Certain corporations filing as part of a combined group, line B, enter the EIN of the designated agent (Article 9-A), or parent (Article 33).
- On line D, mark an X in the box.
- Do not complete line A, line C, or lines 1 through 16.
- Complete your business information and file by the original due date of the combined return (see Where to file).

Note: Nontaxpayer members of a combined group are not required to file a separate Form CT-5, regardless of whether or not they are included on Form CT-5.3.

Filing, or failing to file, a particular extension request does not in any way impact who must be included in a combined group.

New York S corporations

To request one six-month extension of time to file Form CT-3-S, New York S Corporation Franchise Tax Return, New York S corporations must file Form CT-5.4, Request for Six-Month Extension to File New York S Corporation Franchise Tax Return. We will not grant additional extensions beyond six months to New York S corporations.

A New York S corporation is:

a corporation subject to tax under Article 9-A that has elected to be a New York S corporation by filing Form CT-6, Election by a Federal S Corporation to be Treated as a New York S Corporation, or
a federal S corporation that has not made the New York S election but meets the requirements of Tax Law, Article 22, section 660(i) (and is therefore deemed to be a New York S corporation).

Article 9 filers

To request a three-month extension to file a franchise tax return and MTA surcharge return, Article 9 taxpayers must file Form CT-5.9, Request for Three-Month Extension to File.

Exceptions to filing Form CT-5.9 for an extension of time to file:

Providers of telecommunication services filing Form CT-186-E, Telecommunications Tax Return and Utility Services Tax Return, must use Form CT-5.9-E, Request for Three-Month Extension to File Form CT-186-E.
Taxpayers subject to former Tax Law section 186 filing Forms CT-186, Utility Corporation Franchise Tax Return, and CT-186-M, Utility Corporation MTA Surcharge Return, must use Form CT-5.6, Request for Three-Month Extension to File Form CT-186.

Approval of request for a six-month extension of time to file

If you properly file Form CT-5 and pay properly estimated tax on or before the original due date of the return, we will grant you a six-month extension of time for filing a franchise tax return or MTA surcharge return.

If you file your return by the extended due date and pay the balance of the tax due with your return, we will not impose late filing or late payment penalties.

Interest applies to any tax not paid by the original due date of the return.

When to file

File Form CT-5 on or before the due date of your tax return.

Type of corporation	Due date of extension
Businesses filing Form CT-13	4½ months following the end of the tax period
Employee trusts (as described in Internal Revenue Code section 401(a))	3½ months following the end of the tax period
Taxable domestic international sales corporation (DISC)	8½ months following the end of the tax period
All others	3½ months following the end of the tax period

If you cannot file within the six-month extended period, you may request two additional three-month extensions by filing Form CT-5.1, Request for Additional Extension of Time to File, for each extension.
