What the New York Form IT-370 Is For

The New York Form IT-370 2013 is used to request an extension of time to file a New York State individual income tax return when the original deadline cannot be met. The form applies to taxpayers filing Form IT-201 or Form IT-203 and grants additional time for filing without changing payment requirements.

When You’d Use New York Form IT-370

This form is used when a taxpayer needs more time to complete a New York State income tax return but can still submit the extension request by the original due date. It is commonly used when income documents are delayed or tax calculations remain incomplete before filing.

Key Rules or Details for 2013

  • Filing deadline requirement: The IT-370 extension form must be submitted on or before the original tax return due date to remain valid and prevent the return from being treated as late-filed.
  • Filing extension only: This NY tax extension form provides additional time to file paperwork, but does not extend the deadline to pay any taxes owed for the 2013 tax year.
  • Payment threshold rules: To minimize exposure to penalties and interest, at least 90% of the total tax liability must be paid by the original deadline.
  • Separate federal filing: Filing a federal extension does not satisfy New York requirements because a New York tax filing extension must be requested using this state-specific form.
  • Joint filer identification: Taxpayers filing jointly must list both full Social Security numbers, while separate filers must submit individual extension forms and payments.

Step-by-Step (High Level)

Step 1: Determine whether an extension is needed

Review tax records and filing readiness to confirm whether the return can be completed by the original deadline or if additional time is necessary to file accurately.

Step 2: Estimate total tax liability

Calculate estimated New York State, city, and applicable local taxes using available income records and prior returns to determine the payment amount required with the extension request.

Step 3: Complete the extension form accurately

Enter complete identifying information, select applicable tax categories, and include any special condition codes that apply to the taxpayer’s filing situation.

Step 4: Submit payment and file on time

Submit the completed IT-370 extension form with the required payment and ensure it is postmarked or transmitted by the original filing deadline.

Common Mistakes and How to Avoid Them

  • Missing the filing deadline: Submitting the extension after the original due date invalidates it, which can be avoided by filing several days early or using confirmed electronic submission methods.
  • Incomplete Social Security numbers: Providing partial identification information delays processing, which can be prevented by carefully reviewing that all required Social Security numbers are fully entered.
  • Underestimating tax liability: Paying too little with the extension increases penalties, which can be avoided by using conservative estimates based on prior-year returns and current income data.
  • Assuming federal coverage applies: Relying solely on a federal extension leads to state penalties, which you can avoid by filing the NY tax extension form separately.
  • Incorrect mailing address: Sending the form to the wrong processing location delays handling, which can be avoided by verifying whether a payment is included before mailing.
  • Forgetting to include the required payment: Submitting the extension without sufficient payment can result in penalties, which can be avoided by carefully calculating your estimated tax liability and submitting payment with the IT-370 extension form.
  • Failing to claim the extension payment later: Extension payments are not applied automatically, which can be avoided by entering the payment amount on the correct line when filing the completed return.

What Happens After You File

If the taxpayer correctly and timely files New York Form IT-370 2013, they automatically receive a six-month extension in New York for filing the return. Payments are credited to the taxpayer’s account, interest accrues on unpaid balances, and the completed return must be filed by the extended deadline.

FAQs

Does this form extend the time to pay New York taxes?

This form does not extend the time to pay taxes. Payment is still due by the original filing deadline, and interest will be applied to any unpaid balance, even with a valid extension.

Can a federal extension replace this form?

A federal extension does not replace this requirement. New York requires a separate extension request using this form to qualify for a filing extension.

Who must file this form?

Any individual taxpayer who cannot file a New York State income tax return by the original deadline must file this form to request additional filing time.

Is this form used for amended returns?

This form is not used for amended returns. Amended returns require separate amendment forms, which must be filed after the original return has already been submitted.

What happens if the return is not filed by the extended deadline?

Failure to file by the extended deadline results in late filing penalties, which are calculated based on the original due date, despite the previously granted extension.

Does this form apply to prior tax years?

This version applies specifically to the 2013 tax year, and different versions are required for other tax years when requesting a tax extension for New York.
