Tax returns are due on April 15 in most years, but that date applies only if you owe money or expect a refund

The April 15 important date is real, but it does not mean everyone must file by then. If you do not owe federal income tax and do not expect a refund, you are not required to file at all — though filing anyway often makes sense because most people are owed money back. If you do file, April 15 is the hard stop: the IRS charges penalties and interest on unpaid tax after that date, even if you filed late.

The important date shifts to the next business day if April 15 falls on a weekend or federal holiday. In 2024, April 15 was a Monday, so that was the important date. In 2025, April 15 is a Tuesday. Check the IRS website each year if April 15 falls on a Friday, Saturday, or Sunday, because the important date moves forward to Monday.

You do not need to wait until April 15 to file. Most people file between late January and mid-March, when W-2 forms and 1099 forms arrive from employers and financial institutions. Filing early means you receive refunds faster — usually within 21 days if you choose direct deposit.

Key Takeaways

  • April 15 is the important date to file or pay taxes owed, but you only must file if you owe money or are owed a refund.
  • If April 15 falls on a weekend or holiday, the important date moves to the next business day.
  • W-2 forms from employers and 1099 forms from banks and investment firms must reach you by January 31, so you can file as early as late January.
  • Filing early by direct deposit usually gets your refund to your bank account within 21 days.
  • If you cannot file by April 15, you can request an automatic six-month extension, but it delays only filing — not payment of taxes owed.

When employers and financial institutions must send you tax documents

Before you can file, you need the forms that show your income. Your employer must send you a W-2 by January 31. Banks, investment firms, and mortgage companies must send you 1099 forms (the exact type depends on the income: 1099-INT for interest, 1099-DIV for dividends, 1099-NEC for self-employment income) also by January 31.

If you do not receive a W-2 or 1099 by early February, contact the employer or institution directly — do not wait. If they cannot locate it, you can file without it and amend your return later, but that creates extra work. Some employers mail forms late, so check your email and postal mail through mid-February.

Once you have all your documents, you can file when ready. You do not have to wait until March or April. The IRS begins processing returns in late January, so filing in February or early March often means your refund arrives by mid-March.

What happens if you miss the April 15 important date

If you owe tax and do not file by April 15, the IRS charges a failure-to-file penalty of 5 percent of the unpaid tax for each month you are late, up to 25 percent total. You also owe interest on the unpaid amount, compounded daily. These charges add up quickly, so filing late is expensive.

If you are owed a refund and file late, you do not face a penalty, but you lose the refund entirely if you do not file within three years of the original important date. For example, if you were owed a refund for 2022 and did not file by April 15, 2025, the IRS keeps the money.

The penalty applies to the tax you owe, not to the act of filing late itself. If you file late but owe no tax, there is no penalty — only interest on any unpaid amount.

How to request a filing extension

You can request an automatic six-month extension by filing Form 4868 with the IRS before April 15. This moves your filing important date to October 15. You do not need a reason, and the IRS grants it automatically — you do not have to wait for approval.

An extension delays only filing, not payment. If you expect to owe tax, you must estimate what you owe and pay it by April 15 anyway. If you do not pay by April 15, you owe interest and penalties on the unpaid amount, even though your filing important date is now October 15. The extension is useful only if you need time to gather documents, not if you need time to save money for taxes.

File Form 4868 online through the IRS website, through tax software, or by mail. Online filing is fastest and gives you when ready confirmation.

Different important date for self-employed people and business owners

If you are self-employed or own a business, your important date is still April 15, but you may also owe quarterly estimated tax payments on April 15, June 15, September 15, and January 15 of the following year. These payments are separate from your annual return and are due even if you have not filed your return yet.

Quarterly payments are required if you expect to owe $1,000 or more in tax for the year. If you miss a quarterly payment, you owe penalties and interest on that payment alone, separate from any penalties on your annual return. Many self-employed people use tax software or a tax professional to calculate quarterly payments and set reminders.

If you file Form 4868 to extend your annual return to October 15, your quarterly payments are still due on their regular dates. The extension covers only your annual return filing, not your quarterly obligations.

State tax return important date

Most states follow the federal April 15 important date, but some states have different dates or no income tax at all. Nine states have no state income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only dividends and interest, not wages). If you live in one of these states, you file only federal returns.

If you live in a state with income tax, check your state's tax agency website for the exact important date — it is usually April 15, but some states extend it by a few days if April 15 falls on a weekend. State extensions are separate from federal extensions, so you may need to file Form 4868 with the IRS and a separate extension form with your state.

If you work in one state but live in another, you may owe tax to both states. Each state has its own rules about who must file, so contact both state tax agencies or use a tax professional if you work across state lines.

When to file if you expect a refund

If you expect a refund, file as soon as you have all your documents — usually by late February or early March. The IRS processes returns in the order they are received, and filing early means your refund arrives faster. Direct deposit refunds typically arrive within 21 days of the IRS accepting your return.

Do not wait until April to file if you are owed money. The only reason to delay is if you are missing a document, such as a 1099 from a financial institution. Once you have everything, file when ready.

If you file electronically through tax software or a tax professional, the IRS usually accepts your return the same day. If you mail a paper return, allow two to three weeks for the IRS to receive and process it before it begins the 21-day refund clock.

Frequently Asked Questions

What if April 15 falls on a Saturday or Sunday?

The important date moves to the next business day. If April 15 is a Saturday, the important date is Monday, April 17. If April 15 is a Sunday, the important date is Monday, April 16. Check the IRS website each year to confirm, because the exact date depends on whether a federal holiday falls on the Monday after the weekend.

Can I file my return before I receive my W-2?

No. You need your W-2 to report your wages accurately. If your employer is late sending it, contact them directly. If they cannot locate it by mid-February, ask for a wage and tax statement (Form W-2c, a corrected version) or a written statement of your wages. You can then file and amend later if the official W-2 shows different amounts.

Do I have to file if I did not work all year?

Not if you earned below the filing threshold for your age and filing status. The threshold varies by year and situation. For 2024, a single person under 65 must file if they earned $14,600 or more. Check the IRS website for your specific situation, because thresholds change yearly.

What happens if I file my return and then receive a corrected 1099?

Contact the IRS or use tax software to file an amended return (Form 1040-X) showing the corrected information. You have three years from the original important date to file an amended return. If the correction means you owe more tax, file the amended return as soon as possible to avoid additional interest charges.

If I get an extension to October 15, do I still owe taxes by April 15?

Yes. An extension delays filing only, not payment. If you expect to owe tax, estimate the amount and pay it by April 15. If you do not pay by April 15, you owe interest and penalties on the unpaid amount, even though you have until October 15 to file your return.
