Frequently asked questions
When are state taxes due for the 2025 tax year?
Most states align their individual income tax filing deadline with the federal deadline of April 15, 2026. A handful set their own dates (for example, Virginia and Louisiana are later), and nine states have no individual income tax at all. Any deadline that lands on a weekend or holiday moves to the next business day.
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.
Does a state extension extend the time to pay?
Almost never. An extension extends the time to file, not to pay. Pay what you expect to owe by the original deadline to avoid penalties and interest.
Dates are the standard statutory deadlines for the 2025 tax year and move to the next business day when they fall 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.
