What the New York Form IT-370 (2015) Is For
New York Form IT-370 (2015) is used to request additional time to file a New York State individual income tax return. The IT-370 extension form provides an automatic six-month extension of NY grants to eligible taxpayers who file by the original deadline and meet payment requirements.
When You’d Use New York Form IT-370 (2015)
Taxpayers use New York Form IT-370 (2015) when they are unable to complete their state return by the regular due date. Common reasons include missing documents, complex income situations, or coordination with a federal return that affects state reporting.
Key Rules or Details for 2015
- Filing deadline requirement: New York Form IT-370 (2015) must be submitted by the original return due date to remain valid. Late submissions do not create an extension for filing taxes in New York.
- Payment obligation: The IT-370 extension form does not extend the time to pay taxes owed. Estimated tax payments should be submitted on time to reduce penalties and interest.
- Automatic approval: The automatic six-month extension NY provides does not require authorization or confirmation. Filing the form correctly and on time automatically grants the extension.
- Federal extension limitation: A federal extension does not replace the NY tax extension form. New York requires Form IT-370 to be filed separately for state purposes.
- Interest assessment: Interest continues to accrue on unpaid balances starting at the original due date. An extension applies only to filing, not to payment timing.
Step-by-Step (High Level)
Step 1: Confirm filing eligibility
Confirm that you file a New York individual income tax return and need additional filing time. New York Form IT-370 (2015) applies to resident, nonresident, and part-year resident filers.
Step 2: Gather required information
Collect Social Security numbers, estimated tax liability amounts, withholding totals, and prior estimated payments. Accurate figures support correct payment calculations and reduce issues when filing the final return.
Step 3: Calculate estimated payment
Estimate the total New York tax owed for 2015, subtract payments already made, and determine the balance due. Submitting an accurate payment helps limit penalties and interest charges.

Common Mistakes and How to Avoid Them
- Missing the filing deadline: Taxpayers can avoid invalid extensions by submitting New York Form IT-370 (2015) by the original due date. Early filing reduces mailing or processing delays.
- Underpaying estimated tax: Carefully estimating total income and deductions can prevent payment shortfalls. Reviewing prior returns provides a reliable reference for ensuring accurate payments.
- Confusing federal and state extensions: This mistake can be prevented by filing the NY tax extension form separately. Federal extensions do not automatically apply to New York returns.
- Providing incomplete identification: Errors can be avoided by entering full Social Security numbers exactly as required. Complete identification ensures that the extension processes are executed correctly and without delay.
- Failing to keep proof of filing: Issues can be avoided by retaining copies of the filed IT-370 extension form and payment confirmation. Documentation helps resolve disputes if the extension status is questioned later.
- Using incorrect tax year information: Errors can be prevented by confirming the form clearly reflects the 2015 tax year. Using the wrong year can delay processing and render the extension request invalid.
- Failing to file the return by the extended deadline: You can avoid penalties by closely monitoring the new due date. The extension only grants additional time, not an open-ended filing period.
What Happens After You File
After filing New York Form IT-370 (2015), no confirmation notice is issued because approval is automatic. The extension allows additional filing time, while any payment submitted is credited to the taxpayer's account. The final return must still be filed by the extended deadline.
