The Department of Finance participates in the IRS Federal and State 1120 Corporation Tax e-file program. This program allows NYC businesses to file federal and NYC business tax returns together.

Electronic filing is required for tax preparers and businesses that self-file 100 or more NYC returns.

• Annual returns and tax payments must be postmarked by March 15 of the following year, if the corporation chooses an accounting period that is based on the calendar year.
• A corporation that uses an accounting period other than the calendar year (e.g., a fiscal year) must file a return on the 15 day of the third month after the close of its fiscal year.

If a due date falls on a weekend or a legal holiday, the filing must be made by the next business day.

When paying estimated taxes, if the preceding year's tax is more than $1,000, the first installment must be 25% of this tax and be paid when filing either the preceding year's tax return or a request for an extension.

You can request an extension of filing time, but not an extension of time to pay.

Extensions can be filed online through e-Services or by mail.

If you don't file your return or pay the tax by the deadline, or if you overpay, you will be charged interest.

From April 1, 2024 to June 30, 2024, the current interest rates are:

• 12% for underpayments
• 7% for taxes that remain or become overpaid

You must file for a refund within three years of when the return was filed or two years of when the tax was filed and paid, whichever is later.

If no return was filed, you must file within two years from the time the tax was paid.

If you were granted a filing extension, your refund claim must be made within six months after the extension has ended.

If you want to claim a refund based on a previously filed return, and there's a change in the tax liability, you must file an amended return.

The Department of Finance has 90 days from the due date, extended due date, or filing date (whichever is later) to issue a refund without interest.
