Direct answer: In most jurisdictions, the extension gives extra time to file but not to pay. For U.S. federal taxes in 2025, an extension filed by the original due date (typically April 15) extends the filing deadline to October 15, 2025. Taxes owed are still due by April 15, 2025, to avoid penalties and interest. If you filed Form 4868 or used IRS Free File to request the extension, you should file your return by October 15, 2025. If you’re abroad or in a disaster-affected area, special rules may further adjust deadlines. Details and context
- Federal extension timing: Request by the original due date to receive a new filing deadline; the extension moves the filing deadline from April to October, commonly October 15 for individual returns. This is a filing extension only, not a payment extension, so any tax due should be paid by the original due date to avoid penalties. [IRS guidance and multiple tax-education sources indicate October 15 as the extended filing deadline for 2025 if an extension is granted by April 15].
- How to request: You can use IRS Free File to request an automatic extension, or file Form 4868 (by mail or electronically) to obtain the extension. There is no separate penalty for requesting the extension itself, but estimated taxes should be paid by the original due date. [IRS: Need more time to file, request an extension].
- Important caveats: An extension to file does not extend the time to pay. If a balance is owed, pay as much as possible by the original due date to minimize interest and penalties. If you expect a refund, a late filing penalty may still apply if you miss the extended deadline. [IRS reminders and tax guidance in the cited sources].
- Special cases: U.S. citizens living abroad, disaster declarations, and state-level extensions can modify deadlines. For example, certain expatriate deadlines and disaster-related extensions may differ; always verify current official guidance if any of these conditions apply.

If you share your country (and if this is about U.S. federal taxes or a specific state), the exact date can vary. If you’re looking for a country- specific deadline or you need help with Form 4868 steps or estimated payment calculations, I can tailor the guidance.
