IT-370 Instructions: A Comprehensive Guide (Updated 12/11/2025)
Form IT-370 provides an automatic extension for filing New York State income tax returns (IT-200, IT-201, or IT-203). File it with payment before the due date, December 15, 2025.
What is Form IT-370?
Form IT-370, officially titled “Application for Automatic Extension of Time to File Certain New York State Tax Returns,” is a crucial document for taxpayers needing additional time to fulfill their New York State tax obligations. It grants an automatic six-month extension to file various New York State tax returns, including the commonly used IT-200, IT-201, and IT-203 forms.
However, it’s vitally important to understand that Form IT-370 extends the filing deadline, not the payment deadline. Any taxes owed must still be paid by the original due date to avoid penalties and interest. Filing this form doesn’t relieve taxpayers of the responsibility to accurately calculate and remit their tax liability on time.
Furthermore, specific forms like IT-204 (Partnership Return) and IT-205 (Fiduciary Income Tax Return) require a different extension form – IT-370-PF – to be filed. Utilizing the correct form is essential for a valid extension request.
Who Needs to File Form IT-370?
Form IT-370 is intended for individuals and entities who require more time to prepare and submit their New York State income tax returns. This includes taxpayers filing Form IT-200, Form IT-201, or Form IT-203. If you anticipate difficulty meeting the standard filing deadlines – typically December 15th – due to complexities in your financial situation or other legitimate reasons, this form is for you.

Specifically, those who need to gather additional documentation, are awaiting final tax forms (like K-1s), or are experiencing unforeseen circumstances that hinder timely preparation should utilize IT-370. However, remember that partnerships filing Form IT-204 and fiduciaries filing Form IT-205 must use Form IT-370-PF instead.
Essentially, anyone seeking an automatic six-month extension to file their eligible New York State tax return should file Form IT-370 on or before the original filing due date.
Due Dates for Filing IT-370
The Form IT-370 must be filed on or before the original due date of the New York State income tax return it’s associated with. For most individual taxpayers filing Form IT-200, Form IT-201, or Form IT-203, this means filing IT-370 by December 15, 2025.

Filing IT-370 by this date grants an automatic extension of six months to file the actual tax return. However, it’s crucial to understand that this extension applies only to filing, not to payment. Any taxes owed must still be paid by the original due date to avoid penalties and interest.
If you require an extension beyond the initial six months, further action may be necessary. For partnerships (IT-204) and fiduciaries (IT-205), a different form, IT-370-PF, is used and has its own specific filing deadline. Missing the IT-370 deadline forfeits the automatic extension.
How to Obtain the IT-370 Form
Obtaining Form IT-370, Application for Automatic Extension of Time to File, is readily accessible through several convenient methods. The most direct approach is to download the form directly from the New York State Department of Taxation and Finance official website.
A simple online search for “New York IT-370 form” will quickly lead you to the correct page. The website provides the form in a fillable PDF format, allowing you to complete it digitally before printing. Alternatively, you can print a blank form for manual completion.
While physical copies are less common, you may be able to obtain a form by contacting the New York State Department of Taxation and Finance directly via phone or mail. However, downloading from the website is the fastest and most efficient method. Ensure you are using the most current version of the form, dated for the relevant tax year.

Completing Form IT-370: Step-by-Step
Form IT-370 requires identifying information, extension request details, and the specific tax year/return type. Re-compute and verify filing instructions are accurate before submission.

Section 1: Identifying Information
Section 1 of Form IT-370 focuses on accurately identifying the taxpayer requesting the extension. This crucial section demands your legal name, as it appears on your income tax return – whether that’s Form IT-200, IT-201, or IT-203. Ensure consistency to avoid processing delays.
You’ll also need to provide your complete mailing address, including apartment or suite numbers, and a valid phone number where the New York State Department of Taxation and Finance can reach you if necessary. A valid email address is also requested for electronic communication regarding your extension request.
Furthermore, you must clearly indicate your Social Security Number (SSN) or Employer Identification Number (EIN). For partnerships or fiduciaries filing IT-204 or IT-205, specific instructions apply regarding the appropriate identification number to use. Double-check all entries for accuracy before proceeding, as errors can lead to rejection of your extension request.
Section 2: Extension Request Details
Section 2 of Form IT-370 centers on specifying the details of your extension request. You must clearly state the tax year for which you are requesting the extension – for example, the tax year ending December 31, 2025. Accurately identifying the tax year is paramount for proper processing.
Next, you’ll indicate the type of return you will be filing. Options include Form IT-200 (Resident Income Tax Return), IT-201 (Nonresident and Part-Year Resident Income Tax Return), IT-204 (Partnership Return), or IT-205 (Fiduciary Income Tax Return). Selecting the correct return type is essential.
This section also requires you to specify if you are including a payment with your IT-370 form. If so, indicate the amount of the payment. Remember, filing IT-370 with payment doesn’t eliminate penalties and interest if your tax liability isn’t paid by the original due date. Ensure all amounts are accurately reported.
Section 3: Tax Year and Return Type
Section 3 of Form IT-370 is dedicated to clearly defining the tax year and the specific return type for which you’re requesting an extension. This is a crucial step for accurate processing by the New York State Department of Taxation and Finance.
You must explicitly state the tax year covered by the extension request. For instance, if you’re seeking an extension for your 2025 tax obligations, clearly indicate “2025” in the designated field. Accuracy here prevents delays or rejections.
Subsequently, you’ll identify the relevant tax return form. Common options include IT-200 (Resident Income Tax Return), IT-201 (Nonresident/Part-Year Resident), IT-204 (Partnership Return), and IT-205 (Fiduciary Income Tax Return). If requesting an extension for IT-204 or IT-205, you’ll utilize Form IT-370-PF instead of the standard IT-370.
Correctly specifying both the tax year and return type ensures your extension request is properly associated with your tax filing obligations.

Filing Options for IT-370
IT-370 can be filed with or without payment. Filing with payment ensures timely tax remittance, while filing without payment extends only the filing deadline.
Filing IT-370 with Payment
When filing Form IT-370 alongside your tax payment, ensure you submit both on or before the original due date of your New York State income tax return – typically December 15, 2025. This method secures an automatic extension of time to file your return, but it does not extend the time to pay any taxes owed. Therefore, accurate calculation and full remittance of estimated taxes are crucial.
To facilitate this process, you can utilize various payment methods accepted by the New York State Department of Taxation and Finance. These options may include electronic funds transfer, credit card payments, or check/money order submissions. Always retain a copy of your IT-370 form and payment confirmation for your records. Filing with payment demonstrates good faith and avoids potential penalties associated with late tax payments, even while benefiting from the extended filing timeframe.
Remember, this option applies to Form IT-200, IT-201, and IT-203 returns.
Filing IT-370 Without Payment
You can file Form IT-370 to request an extension of time to file your New York State income tax return (IT-200, IT-201, or IT-203) even if you are unable to submit payment with the form. However, be aware that this does not grant an extension of time to pay. Any taxes owed must still be paid by the original due date – December 15, 2025 – to avoid penalties and interest.
If you qualify for an extension beyond six months, filing IT-370 is still required. For partnership (IT-204) or fiduciary (IT-205) returns, utilize Form IT-370-PF instead. Submitting the form without payment simply extends the filing deadline, allowing more time to gather necessary documentation and complete your return accurately.
Ensure the form is filed on or before the original due date to be considered valid. Late filing, even without payment, may result in penalties. Keep a copy of the submitted IT-370 for your records;
Electronic Filing Options
While specific details regarding direct electronic filing of Form IT-370 aren’t explicitly stated, taxpayers generally utilize software or services approved by the New York State Department of Taxation and Finance to file extensions. These platforms often integrate the IT-370 form within their broader tax filing systems.
Check with your tax preparation software provider to confirm if IT-370 electronic filing is supported. Alternatively, explore authorized e-file service providers listed on the NYS Tax Department website. Electronic filing offers advantages like faster processing, reduced errors, and confirmation of receipt.
If encountering issues with electronic filing, ensure all required fields are completed accurately. If problems persist, consult the software’s help resources or contact the e-file provider’s support team. Remember to retain a copy of the electronic submission confirmation for your records, alongside any associated payment confirmations.

IT-370 and Other Related Forms

Form IT-370 is used with IT-204 (Partnership Return) and IT-205 (Fiduciary Income Tax Return) to request filing extensions. It also relates to IT-200/201/203.
IT-370 vs. IT-204 (Partnership Return)
Form IT-370 and Form IT-204, the Partnership Return, are distinct but often used in conjunction when a partnership requires an extension of time to file its New York State income tax return. While IT-204 is the actual return reporting the partnership’s income and operations, IT-370 serves specifically as the application for an automatic extension of time to file that IT-204.
To obtain an extension for the IT-204, the partnership must file IT-370 on or before the original due date of the partnership return. Filing IT-370 doesn’t extend the time to pay any tax due; payment must still be made by the original due date to avoid penalties and interest. The extension granted by IT-370 provides additional time – typically six months – to prepare and submit the complete IT-204 return.
Essentially, IT-370 is the procedural form requesting more time, while IT-204 is the substantive return containing the financial information. They work together to ensure compliance with New York State tax regulations.
IT-370 vs. IT-205 (Fiduciary Income Tax Return)
Form IT-370 plays a similar role in relation to Form IT-205, the Fiduciary Income Tax Return, as it does with the partnership return (IT-204). IT-205 is used to report income for estates and trusts, and when a fiduciary needs additional time to prepare and file this return, IT-370 is the form utilized to request an extension.
Filing IT-370 on or before the original due date of the fiduciary return grants an automatic extension of time to file IT-205. However, it’s crucial to remember that this extension applies only to the filing of the return itself, not to the payment of any taxes owed. Any tax liability must be paid by the original due date to avoid penalties and interest charges.
Therefore, IT-370 is the procedural request for an extension, while IT-205 is the substantive return detailing the estate or trust’s financial activity. They are distinct forms serving different purposes within the New York State tax filing process.
IT-370 and Form IT-200/IT-201/IT-203
Form IT-370 is directly linked to Form IT-200 (Resident Income Tax Return), IT-201 (Nonresident and Part-Year Resident Income Tax Return), and IT-203 (Nonresident Alien Income Tax Return). These are the core individual income tax forms for New York State residents and those with income sourced from New York.
When taxpayers require more time to gather necessary documentation or complete these returns accurately, they utilize IT-370 to request an automatic extension of time to file; The instructions for IT-200, IT-201, and IT-203 specifically reference IT-370 as the appropriate form for this purpose.
Remember, filing IT-370 doesn’t extend the time to pay any taxes due. Taxpayers must estimate and remit payment with the IT-370 form to avoid penalties. The extension granted by IT-370 solely pertains to the filing deadline for the underlying IT-200, IT-201, or IT-203 return.

Important Considerations & Troubleshooting
IT-370 filing doesn’t extend payment deadlines; re-compute if filing instructions aren’t printing. Advantech products have warranty repairs, and Yoga 370 has battery safety.
Re-computing and Filing Instructions

Verification is Key: After re-computing, carefully review the generated filing instructions to confirm they accurately reflect your tax situation and the extension period. Ensure all details, including deadlines and required forms, are correct before submitting your return; A thorough check minimizes potential delays or rejections by the tax authorities.
Software Specifics: Remember that the exact menu options may vary slightly depending on the tax software you are using. Consult your software’s help documentation for specific guidance on re-computing and accessing filing instructions.
