Frequently asked questions
Which year do I pick?
Pick the calendar year the deadline falls in. Your 2025 return is due in spring 2026, so it is on the 2026 page, together with the 2026 estimated payments. The 2025 page covers the 2024 return and the 2025 estimated payments.
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 statutory deadlines 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.
