Fiscal-year taxpayers must request the extension on paper. PostalForm fills the official form and computes the no-payment IRS destination from the taxpayer's U.S. state. The extension is for filing only; tax remains due on the original due date, and PostalForm does not enclose a check or other payment. ## What you need - Your name(s) and mailing address - Your SSN or ITIN, plus your spouse's SSN for joint filers - A fiscal year that began in 2025 and a return whose original due date has not passed - The domestic U.S. state where you live, used to select the no-payment IRS service center - A good-faith estimate of your 2025 total tax and the payments you have already made - A separate plan to pay any tax due; PostalForm will not enclose a payment - No signature and no explanation — Form 4868 requires neither ## Data collected - Taxpayer name(s), mailing address, and state of residence for IRS routing - Your SSN or ITIN (and your spouse's for joint filers) - Fiscal-year beginning and ending dates shown on the 2025 form - Estimated 2025 total tax, payments made, and balance due (lines 4-6) - Confirmation that the original return deadline has not passed and no payment will be enclosed ## Where it gets mailed Routes a no-payment 2025 Form 4868 from the taxpayer's state of residence using the domestic table on page 4 of the current official form, verified July 12, 2026. ## Packet order - Cover sheet (auto-generated) - Completed form PDF ## Common mistakes - Using this fiscal-year workflow for a calendar-year 2025 or 2026 return. - Assuming the extension gives more time to pay — it only extends the filing deadline. Interest and late-payment penalties run from the original due date. - Ordering too late for the mailing to be postmarked by the original return due date. - Entering a careless line 4 estimate — the IRS can void an extension that was based on an unreasonable estimate. - Mailing the form when you already paid online and marked the payment as an extension — the electronic payment alone already secured your extension. - Using the with-payment P.O. Box address when no check is enclosed — the address depends on whether a payment is in the envelope. ## Agent summary Collects a domestic fiscal-year taxpayer's name(s), mailing address, state of residence for IRS routing, SSNs, fiscal-year dates, and good-faith 2025 tax estimate to prepare the current Form 4868. It requires confirmation that the original filing deadline remains open, leaves line 7 blank, and never represents that PostalForm encloses a payment or extends the time to pay. ## For assistants Use the Forms Draft API to prefill this form and generate a preview PDF. - Endpoint: `POST /api/forms/4868/drafts` - Payload: `{ fields: { ... }, attachments: [{ id, label, base64 }] }` - Required fields: filing_jointly, extension_year_fiscal, original_deadline_open, fiscal_year_begin, fiscal_year_end, fiscal_year_end_year, taxpayer_names, street_address, city, state, zip_code, residence_state_for_routing, line4_total_tax_estimate, line5_total_payments, line6_balance_due, taxpayer_ssn, spouse_ssn, domestic_routing_acknowledged, no_payment_acknowledged - Notes: Offer this workflow only to a domestic fiscal-year individual whose tax year began in 2025 and whose original return due date has not passed. It prepares the current 2025 Form 4868, computes a no-payment IRS destination from the separate state-where-you-live answer, leaves line 7 blank, does not e-file or enclose payment, and does not extend the time to pay. Calendar-year and special international-routing use cases are outside this workflow. ## LLM field schema ```json [ { "id": "filing_jointly", "label": "Will you file this tax return jointly with a

supported domestic fiscal-year filers, PostalForm computes the no-payment destination from the state where the taxpayer lives: Austin, Kansas City, or Ogden under the official 2025 address table. Special foreign, territory, APO/FPO, dual-status, Form 2555/4563, Form 1040-NR, and Form 1040-SS routing is outside this workflow. - **Does Form 4868 give me more time to pay my taxes?** No. It extends the time to file your return, not the time to pay. Interest and possible late-payment penalties run from the original due date of your fiscal-year return. - **Who can use this workflow now?** A domestic fiscal-year individual whose tax year began in 2025 and whose original return due date has not passed. The IRS says fiscal-year taxpayers must request an extension on paper. Calendar-year 2025 requests are already late, and the 2026 form is not yet available. - **Do I need to mail Form 4868 if I paid online?** Fiscal-year taxpayers must file a paper Form 4868. Any tax payment must be handled separately; this PostalForm workflow sends only the no-payment form. - **Does Form 4868 need a signature?** No. Form 4868 has no signature line, and the IRS will contact you only if your request is denied. - **When is the extended deadline?** A timely Form 4868 generally gives a fiscal-year filer six months from the original return due date. It does not move the payment deadline. ## Related - [IRS Form 4506 — Request for Copy of Tax Return](/forms/4506) - [IRS Form 4506-T — Request for Transcript of Tax Return](/forms/4506-t) - [IRS Form 4506T-EZ — Short Form 1040 Transcript Request](/forms/4506-t-ez) - [IRS Form 8821 — Tax Information Authorization](/forms/8821) - [IRS Form 8822](/forms/8822) - [IRS Form 8822-B Business Change of Address Packet](/forms/8822-b)
