What form do I file for a LLC in New York?
LLC entities in New York file using Form State LLC return. You can download the form from New York Department of Taxation and Finance at https://www.tax.ny.gov.
Can I get an extension for my New York LLC tax return?
Yes. New York allows an extension for LLC returns until Sep 15, 2026. Note that an extension gives you more time to file, not more time to pay — any tax owed is still due by the original deadline of Mar 16, 2026.
What are the penalties for filing late in New York?
New York typically charges a failure-to-file penalty (usually 5% of unpaid tax per month, up to 25%) and a failure-to-pay penalty (usually 0.5-1% per month). Interest also accrues on unpaid balances. Filing for an extension by the original deadline avoids the failure-to-file penalty but not the failure-to-pay penalty.
