Which states accept the federal extension?
The extension is to file, not to pay, in every state: pay what you expect to owe by the original date. The rule column comes from each state's revenue department; the state page carries the source link and the form.

Frequently asked questions
When are state taxes due in 2025?
Most states file the 2024 individual return on the federal date, April 15, 2025. Delaware (April 30), Hawaii (April 20), Iowa (April 30), Louisiana (May 15), Virginia (May 1) set their own dates. Nine states have no individual income tax. A deadline that lands on a weekend or holiday moves to the next business day.
Which states accept the federal extension automatically?
Most do, either by honoring Form 4868 or by granting everyone an automatic extension, but a handful require their own form. The extension table below lists each state's rule with a link to the state source. In every state the extension is to file, not to pay.
When are state estimated tax payments due in 2025?
Most states follow the federal 2025 schedule of April 15, 2025, June 16, 2025, September 15, 2025, January 15, 2026. Virginia's first installment is May 1, Hawaii and Iowa use different days, and some states do not require estimates at all.
Do all states have an income tax deadline?
No. Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire don't levy a broad individual income tax, so there's no state individual return to file, though federal deadlines still apply.
Dates are the statutory deadlines that fall in 2025 and move to the next business day when they land on a weekend or holiday. Always confirm current dates with your state's Department of Revenue or the IRS. This is general information, not tax advice.
