Tax season runs from January 2 through April 15 each year in the United States

The IRS opens its filing system on January 2 and closes it on April 15 — that is the hard deadline for most people to submit their federal tax return. If April 15 falls on a weekend or holiday, the deadline moves to the next business day. State tax deadlines usually match the federal deadline, though a few states have different dates.

You do not have to file on January 2. Many people file in February or March when they have all their documents together. Filing early can mean getting a refund faster, but there is no penalty for waiting until late March or early April as long as you file before the deadline.

If you cannot file by April 15, you can request an extension from the IRS. An extension gives you until October 15 to submit your return, but it does not extend the deadline to pay any taxes you owe — those are still due by April 15.

Key Takeaways

  • The IRS accepts federal tax returns from January 2 through April 15 each year, with April 15 being the final deadline.
  • You can file anytime during this window; filing earlier usually means receiving a refund sooner.
  • If you need more time, you can request an extension to October 15, but taxes owed must still be paid by April 15.
  • State tax deadlines typically match the federal deadline, though you should check your specific state's rules.
  • If April 15 falls on a weekend or federal holiday, the deadline automatically moves to the next business day.

Why tax season starts on January 2

January 2 is when the IRS begins accepting returns because employers, banks, and other institutions need time after the calendar year ends to prepare the documents you need to file. W-2 forms from employers, 1099 forms from banks and investment accounts, and mortgage interest statements must all be mailed to you by January 31. The IRS waits a few days into January to give people time to receive these documents before filing.

Some people can file before January 2 if they have all their documents early — for example, if they receive a W-2 in late December. However, the IRS will not process any returns submitted before January 2, so there is no advantage to submitting early.

Why the deadline is April 15

April 15 has been the federal tax deadline since 1913. Congress set it as a fixed date to give people roughly three and a half months to gather documents and file. The date has remained the same for over a century, though Congress can change it by law if it chooses to do so.

The April 15 deadline applies to most individual filers. Self-employed people, business owners, and people filing certain types of returns may have different deadlines, but April 15 is the standard for W-2 employees and people claiming refunds.

What happens if you miss the April 15 deadline

If you do not file by April 15 and do not have an approved extension, the IRS will charge you a failure-to-file penalty. The penalty is usually 5 percent of the taxes you owe for each month your return is late, up to 25 percent total. If you owe taxes and do not pay by April 15, you will also owe interest on the unpaid amount, calculated daily.

If you are owed a refund and you miss the deadline, you do not face a penalty, but you lose the right to claim that refund after three years. For example, if you were owed a refund for 2023 and did not file by April 15, 2026, you cannot claim it.

How to request an extension

You can request an automatic six-month extension by filing Form 4868 with the IRS. You do not need a reason to request an extension, and the IRS will grant it automatically if you file the form by April 15. You can file Form 4868 on paper by mail, electronically through tax software, or through the IRS website.

An extension moves your filing deadline to October 15, but it does not move your payment deadline. If you owe taxes, you must pay them by April 15 even if you have an extension. If you cannot pay the full amount by April 15, you can set up a payment plan with the IRS, but interest and penalties will continue to accrue on the unpaid balance.

State tax deadlines and variations

Most states follow the federal April 15 deadline for income tax returns. However, a few states have different dates or do not have income tax at all. Some states also allow extensions that differ from the federal extension — for example, a state might grant a 90-day extension instead of 180 days.

If you live in a state with income tax, check your state's tax agency website for the exact deadline and extension rules. If you live in a state without income tax, you only need to file a federal return. If you live in one state but earned income in another, you may need to file returns in both states.

When you receive your refund

If you are owed a refund, the IRS typically processes it within 21 days of receiving your return. If you file electronically and choose direct deposit, the refund usually arrives in your bank account within two to three weeks. If you request a paper check, it can take four to six weeks.

Refunds are processed in the order they are received, so filing early in January or February usually means a faster refund than filing in late March or early April. However, the IRS may hold your refund for review if there are questions about your return, which can delay payment by several weeks or months.

Frequently Asked Questions

Can I file my taxes before January 2?

You can prepare your return before January 2, but the IRS will not process it until January 2 or later. There is no benefit to submitting before that date, so most people wait until they have all their documents.

What if April 15 falls on a weekend?

If April 15 falls on a Saturday or Sunday, the deadline moves to the following Monday. If April 15 falls on a federal holiday, the deadline moves to the next business day. The IRS announces the exact deadline each year.

Do I have to file by April 15 if I do not owe taxes?

If you are owed a refund, there is no penalty for filing late, but you can only claim the refund for three years after the original deadline. If you do not owe taxes and are not owed a refund, you do not have to file at all.

Can I get an extension if I live outside the United States?

U.S. citizens and residents living abroad get an automatic two-month extension to June 15 without filing Form 4868. If you need more time, you can file Form 4868 to extend to October 15.

What if I cannot pay my taxes by April 15?

You can set up a payment plan with the IRS to pay over time. Interest and penalties will continue to accrue on the unpaid balance, but a payment plan prevents additional failure-to-pay penalties. You can request a plan online, by phone, or through your tax software.
