New York Tax Extension Form: To request a New York extension, file Form CT-5 by the original due date of your return. Note that Form CT-5 must be filed electronically via NY Online Services for Businesses: www.tax.ny.gov/online/bus
New York Extension Payment Requirement: An extension of time to file is not an extension of time to pay. If you owe New York tax, it must be paid by the original deadline to avoid interest and penalties. In fact, you're required to pay your properly estimated tax liability in order to obtain a New York tax extension. You can make an extension payment using Form CT-200-V, or pay electronically through NY Online Services for Businesses: www.tax.ny.gov/online/bus
New York Tax Extension Tips: The State of New York does not accept the Federal tax extension (IRS Form 7004) in place of the state application (Form CT-5).
If you’re unable to file and pay electronically, you may order the paper versions of Form CT-5 and Form CT-200-V by calling the New York State Department of Taxation and Finance at (518) 457-5431.
