Application for Automatic Extension of Time To File a U.S. Individual Income Tax Return (Form 4868, 2025 tax year)

Request an automatic extension of time to file the U.S. individual income tax return (Form 1040 series) for the 2025 tax year, using IRS Form 4868. The extension is to FILE, not to PAY: any tax owed is still due by the original deadline, and this form lets the filer estimate that liability and submit a payment. This document describes the 2025 edition; a new edition is published each tax year (see the edition member). It does not submit the request; the live IRS source is always authoritative (see VERIFICATION.md).

    patternclassification: sensitive-pii

Estimate your 2025 tax and payment

  • estimatedTotalTaxLiability number required

    Your best estimate of the total income tax you expect to owe for the 2025 tax year, in U.S. dollars. Enter 0 if you expect to owe no tax; a properly estimated entry is required for the extension to be valid.

  • totalPayments number required

    The total 2025 tax payments you have already made (withholding, estimated payments, and applicable credits), in U.S. dollars. Enter 0 if none.

  • balanceDue number required

    Line 4 minus line 5, in U.S. dollars; if line 5 is more than line 4, enter 0. This is the amount the IRS still expects to be paid by the original filing deadline — the extension does not extend the time to pay.

  • amountPaying number required

    The amount you are paying with this extension request, in U.S. dollars. May be 0; paying the balance due avoids interest and possible penalties.

  • outOfCountry boolean optional

    Check (true) if, on the regular due date of your return, you are out of the country and a U.S. citizen or resident, as defined in the Form 4868 instructions. 'Out of the country' filers may qualify for additional time.

  • form1040nrNoWages boolean optional

    Check (true) if you file Form 1040-NR and did not receive wages as an employee subject to U.S. income tax withholding, per the Form 4868 instructions (this affects the applicable due date).
