When Are Taxes Due – the standard federal deadline

When are taxes due according to the national rule? For calendar‑year individual filers, the federal return is due on April 15 each year. 
When are tax due, exactly? For 2025, the deadline remains April 15.
However, if April 15 falls on a weekend or a holiday, that may push “when are tax due” to the next business day. 
Why is this important? Because timing matters — missing that “when are tax due” date can mean penalties, interest, and stress.

When Are Taxes Due for extensions and special situations

When are taxes due if you can’t meet the April deadline? You can request a filing extension. But note: while the filing date shifts, the payment date does not. In other words: you still owe taxes by the original deadline. 
So, when are tax due when you get an extension? For many, the federal filing deadline moves to October 15. 
When are tax due for taxpayers living abroad? Those living outside the U.S. may automatically get until June 15 (or June 16) to file, but again any amounts owed are still due by April 15. 
When are tax due for business entities, trusts or non‑calendar year filers? The rules vary based on entity type and fiscal year.

When Are Taxes Due — what about state returns?

Knowing “when are tax due” for the federal return is only part of the equation. State income taxes often follow similar deadlines, but with their own quirks.

Hence, if you’re wondering when are tax due at the state level, it pays to check your specific state’s rules.

How to prepare BEFORE asking “when are taxes due”

When you wonder “when are taxes due,” you need more than just the date — you need a plan. Here are steps to prepare:

1. Gather your documents early
   Collect your W‑2s, 1099s, investment statements, and other income documents. Knowing exactly what you owe helps you meet the real “when are taxes due” payment date.

2. Estimate your tax liability
   Even if you file an extension, you still need to pay what you owe by the original due date. Estimating helps you avoid surprise penalties.

   Once you know when are tax due for your situation, set reminders: e‑file by X, pay by Y. Don’t rely on memory alone.

4. Decide whether you’ll file early or seek extension
   If you expect a refund, earlier is better. If complex, file extension — but get the payment ready.

5. Prepare for payment
   Arrange for funds so that payment is received by the deadline — midnight of the due date in your time zone.

6. Track your notes
   Keep copies of receipts, forms, and confirmation numbers. If you’re later asked “when are tax due” for some specific item (like estimated taxes), you’ll have records.
