The IRS filing season runs from late January through mid-April each year

The IRS typically opens the filing season in late January and sets the tax important date for April 15 of that year. In 2024, the filing season opened on January 29. The exact opening date shifts slightly each year because the IRS coordinates with state tax agencies and needs time to update systems after the previous year closes.

You can file your taxes as soon as you have all your documents in hand — you do not have to wait for the official season to open. Many people file in February or March because that is when W-2 forms, 1099 forms, and other income documents arrive from employers and financial institutions. If you file before those documents reach you, you will likely have to file an amended return later.

The April 15 important date applies to federal taxes. Some states have different important date, and a few states do not have income tax at all. If you owe taxes and miss the April 15 important date, penalties and interest begin to accrue when ready, even if you file just one day late.

Key Takeaways

  • The IRS filing season opens in late January each year, but you can file as soon as you have your W-2s, 1099s, and other income documents.
  • The federal tax important date is April 15, and filing even one day late triggers penalties and interest if you owe money.
  • You can request an automatic six-month extension to file, but this extends only the filing important date, not the payment important date — taxes owed are still due April 15.
  • If you expect a refund, filing earlier in the season means you receive your money sooner, typically within 21 days of the IRS accepting your return.
  • State tax important date may differ from the federal important date, so check your state's rules if you live outside the standard April 15 jurisdiction.

What documents you need before you can file

You cannot file accurately until you have received all forms reporting your income. For W-2 employees, employers must send W-2 forms by January 31. For self-employed people and those with investment income, 1099 forms arrive on different schedules — 1099-NEC and 1099-MISC by January 31, but 1099-INT and 1099-DIV sometimes arrive later in February.

If you are waiting on a document that has not arrived by early February, contact the issuer directly. Employers and financial institutions sometimes send documents late, and you may need to follow up. The IRS does not send these documents — they come from your employer, bank, brokerage, or other income source.

You will also need records of deductions if you itemize, mortgage interest statements (Form 1098), student loan interest statements (Form 1098-T), and proof of any tax credits you claim. Gather these before you sit down to file, whether you file yourself or work with a tax preparer.

Filing early versus filing close to the important date

Filing in February or early March has real advantages. If you expect a refund, the IRS processes returns in the order they arrive, and you will receive your money sooner — typically within 21 days of acceptance if you choose direct deposit. Filing early also means you have time to correct errors before the important date if something goes wrong.

Filing close to April 15 creates risk. If you discover an error after filing, you have little time to fix it. If the IRS has questions about your return, you have less time to respond. If you owe money and miss the important date, penalties begin when ready. There is no advantage to waiting unless you are still gathering documents.

The only reason to file close to the important date is if you genuinely do not have the documents you need. In that case, you can request an extension, but understand that an extension to file is not an extension to pay — if you owe taxes, they are still due on April 15.

How to request a filing extension

You can request an automatic six-month extension by filing Form 4868 with the IRS. This moves your filing important date from April 15 to October 15. You do not need a reason to request the extension, and the IRS grants it automatically if you file the form on time.

The critical point: an extension to file does not extend the payment important date. If you owe taxes, you must pay by April 15 or face penalties and interest. The extension only gives you more time to gather documents and prepare your return. If you cannot pay by April 15, you can set up a payment plan with the IRS, but you must do that before the important date.

File Form 4868 before April 15 if you want the extension. You can file it electronically through tax software, by mail, or through a tax preparer. Filing the form itself is free.

Refunds and direct deposit timing

If you are owed a refund, filing early matters. The IRS typically processes returns within 21 days if you choose direct deposit to a bank account. If you request a paper check, allow four to six weeks. The IRS processes returns in the order received, so a return filed in February arrives in the queue before one filed in March.

Direct deposit is faster and safer than a paper check. You provide your bank account and routing number on your return, and the IRS deposits the refund directly. There is no risk of the check being lost or delayed in the mail.

If the IRS needs to verify information on your return — for example, if there is a discrepancy between what you reported and what your employer reported — the refund is delayed while they investigate. This can add weeks or months to the timeline. Filing accurately the first time prevents this delay.

What happens if you miss the April 15 important date

If you owe taxes and file after April 15, the IRS charges a failure-to-file penalty of 5 percent of the unpaid tax for each month or part of a month that the return is late, up to 25 percent. You also owe interest on the unpaid amount, calculated daily from the original due date. Both penalties and interest compound, so the longer you wait, the more you owe.

If you expect a refund, there is no penalty for filing late — you straightforward receive your refund later. However, there are time limits on how far back you can claim a refund. Generally, you must file within three years of the original important date to claim a refund, though some situations allow longer.

If you cannot file by April 15, file Form 4868 for an extension before the important date. This prevents the failure-to-file penalty from starting. If you have already missed April 15, file your return as soon as possible and be prepared to pay the penalties and interest owed.

State tax important date and special situations

Most states follow the federal April 15 important date, but some differ. Massachusetts and Maine, for example, have April 17 important date in some years. A few states have no income tax at all — Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming do not tax wages. If you live in one of these states, you only file federal taxes.

If you live in one state but work in another, you may need to file in both. The rules vary by state and depend on where you earned the income and where you lived. A tax preparer in your state can tell you whether you need to file multiple returns.

If you are self-employed, you also owe estimated quarterly taxes on April 15, June 15, September 15, and January 15 of the following year. These are separate from your annual return and are due on their own schedule.

Frequently Asked Questions

Can I file my taxes before I receive all my W-2s and 1099s?

You can file, but you should not. Filing without all income documents means your return is incomplete and likely incorrect. You will probably have to file an amended return once the missing documents arrive. It is better to wait until you have everything, then file once and be done.

What if April 15 falls on a weekend or holiday?

The IRS moves the important date to the next business day. If April 15 is a Saturday, the important date becomes Monday, April 17. If it is a Sunday, the important date becomes Monday, April 16. Check the IRS website each year to confirm the exact important date for that year.

Do I have to file if I did not earn much money?

It depends on your income level and filing status. The IRS sets a threshold each year — for 2024, single filers under age 65 with less than $14,600 in income generally do not have to file. However, if taxes were withheld from your paychecks, you should file to get a refund. A tax preparer or the IRS website can tell you whether you must file based on your specific situation.

If I file an extension, when do I actually have to file my return?

Form 4868 gives you until October 15 to file your return. This is six months from the original April 15 important date. You still owe any taxes due by April 15, but you have until October 15 to submit the actual return form.

How long does it take to get a refund if I file by mail?

Paper returns take longer to process than electronic returns. Allow four to six weeks for the IRS to receive, process, and issue a refund by check. Direct deposit is faster — typically 21 days. If you file by mail, use certified mail so you have proof the IRS received it.
