For your 2025 U.S. federal income taxes, the standard deadline to file or request an extension is April 15, 2026, but if you file for an extension (Form 4868) by April 15, 2026, you get until October 15, 2026, to file, though any taxes owed must still be paid by April 15, 2026, to avoid penalties.
For individuals, the last day to file your 2025 taxes without an extension is April 15, 2026. You can submit Form 4868 to request an extension to file later during the year.
If you file taxes after the October 15 extension deadline, the IRS will assess penalties and interest, primarily a failure-to-file penalty (5% per month, max 25%), plus a separate failure-to-pay penalty (0.5% per month) and daily interest on the unpaid taxes, though you can request penalty abatement for reasonable cause like natural disasters. The October deadline is for filing, not paying; if you owe, payment was due in April, so you'll likely face both penalties and interest until you file and pay, but you won't be penalized if you're due a refund.
The IRS will begin accepting 2025 tax returns on Jan. 26, when the agency officially opens the 2026 tax filing season. “The Internal Revenue Service is ready to help taxpayers meet their tax filing and payment obligations during the 2026 filing season,” said IRS Chief Executive Officer Frank Bisignano.

Here's a summary of key changes for the 2025 tax year. The seven federal tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%) are now permanent. Standard deductions increased, plus a new “bonus” deduction for older adults. Child tax credit increased to $2,200 per qualifying child.
Yes, many individual provisions of the Trump-era Tax Cuts and Jobs Act (TCJA) from 2017 are set to expire at the end of 2025, reverting tax law to pre-2017 levels unless Congress acts, with key changes including the standard deduction, SALT deduction cap, and estate tax rules set to change, although legislation like the "One Big Beautiful Bill Act" (OBBBA) has since extended some of these cuts into the future, changing the original expiration cliff.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.

The due date to file your California state tax return and pay any balance due is April 15, 2026. However, California grants an automatic extension until October 15, 2026 to file your return, although your payment is still due by April 15, 2026. No application is required for an extension to file.
If you owe tax and don't file on time (with extensions), there's also a penalty for not filing on time. The failure-to-file penalty is usually five percent of the tax owed for each month, or part of a month, that your return is late, up to a maximum of 25%.
If you don't file your tax return by the October 15 extension deadline, the IRS charges a failure-to-file penalty of 5% per month (up to 25%) on unpaid taxes, plus a failure-to-pay penalty (0.5% per month), and interest on the total amount due, potentially leading to significant costs, though you can request penalty abatement for reasonable cause, and if you're owed a refund, you generally won't face penalties but risk losing your refund if you wait too long (usually over 3 years).
