Form CT-1, Supplement to Corporation Tax Instructions

This form is for general instructions that apply to all corporation tax forms. It includes a variety of topics about how to fill out your form (for example, entry formats and third-party designee), filing and payment information (such as when Form CT-200-V is required), collection options that we may take, tax shelter information, and your rights under the Tax Law. Form CT-1 also has our contact information if you need help, and our privacy notification. For details, see Form CT-1 or visit www.tax.ny.gov (search: CT-1).

Note: All citations are to New York State Tax Law sections unless specifically noted otherwise.

General information

For the purposes of these instructions, the corporation responsible for filing a combined return is referred to as:

for general business corporations, as the designated agent
for insurance corporations, as the parent

Corporations, other than the designated agent or parent, required to pay a fixed dollar minimum tax are member corporations.

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-5.3 and pay the properly estimated combined franchise tax, combined fixed dollar minimum tax on group member corporations, and combined 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, 2, and 9 in these instructions.
The properly estimated combined franchise tax, combined fixed dollar minimum tax on group member corporations, and combined MTA surcharge must either:
- equal or exceed the combined franchise tax, combined fixed dollar minimum tax on group member corporations, and combined 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 combined franchise tax, combined fixed dollar minimum tax on group member corporations, and combined 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 combined franchise tax calculated after you deduct any tax credits and before you add the combined fixed dollar minimum tax on group member corporations.

You must adjust the combined franchise tax, combined fixed dollar minimum tax on group member corporations, and combined MTA surcharge for the preceding tax year as necessary to correct errors in calculation or in the application of tax rate or tax base.

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

Use lines 1 through 8 to calculate the estimated combined franchise tax and combined minimum tax.
Use lines 9 through 13 to calculate the estimated MTA surcharge.
Submit only one Form CT-5.3. Do not submit separate forms for each return.
Submit only one payment of the total combined amount of franchise tax, fixed dollar minimum tax of group member corporations, and MTA surcharge.

Who may file Form CT-5.3

The designated agent or parent 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:

each taxpayer member corporation of a new combined group must also file a separate Form CT-5, Request for Six-Month Extension to File (for franchise/business taxes, MTA surcharge, or both), to extend the time to file for the first period for which the new combined group files a combined return, and
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.

Note: Non-taxpayer corporations included in 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.

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

Approval of request for a six-month extension to file

If you properly file Form CT-5.3 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 combined 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-5.3 on or before the original due date of your combined tax return (3½ months after the end of the tax year).

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

Where to file

Mail Form CT-5.3 to:

NYS CORPORATION TAX
