The IRS opens 2025 tax filing on January 27, 2025

The Internal Revenue Service will begin accepting 2025 tax returns on Monday, January 27, 2025. This is the official start date for the filing season. You can file electronically through tax software, a tax professional, or the IRS Free File program if you meet income limits. Paper returns can be mailed anytime, but electronic filing is faster and more reliable.

The important date to file your 2025 return is Tuesday, April 15, 2026. This is the same date every year unless it falls on a weekend or federal holiday. If you cannot file by April 15, you can request an automatic extension that gives you until October 15, 2026, but an extension to file is not an extension to pay — taxes owed are still due by April 15.

Starting your return as soon as the filing season opens has real advantages. Your employer and financial institutions send tax documents (W-2s, 1099s, and others) throughout January and early February. Filing early means you have time to gather everything without rushing, and you get your refund sooner if one is coming to you.

Key Takeaways

  • The IRS begins accepting 2025 returns on January 27, 2025, and the filing important date is April 15, 2026.
  • Electronic filing through tax software or a tax professional is faster and more accurate than mailing a paper return.
  • You can request an extension to file until October 15, 2026, but taxes owed are still due on April 15.
  • Waiting until January to file gives you time to collect all required documents without rushing.
  • The IRS Free File program is available to people earning under a certain income threshold and costs nothing.

What documents you need before filing

Before you file, gather your income documents. These include W-2 forms from your employer (one for each job), 1099 forms for freelance or contract income, interest and dividend statements from banks and investment accounts, and records of any other income. Your employer must send your W-2 by January 31, and financial institutions must send 1099s by the same date.

You will also need records of deductions or credits you plan to claim. If you itemize deductions, collect receipts for mortgage interest, property taxes, charitable donations, and medical expenses. If you have dependents, gather their Social Security numbers. If you paid for childcare, student loan interest, or education expenses, have those documents ready too.

Do not wait for every document to arrive before starting. You can file as soon as you have your W-2 and any 1099s for income you received. If a document arrives late, you can file an amended return, though this adds time and complexity.

How to file electronically versus by mail

Electronic filing is the faster route. The IRS processes e-filed returns in about 21 days if you claim a refund and choose direct deposit to your bank account. You can e-file through commercial tax software (TurboTax, H&R Block, TaxAct, and others), a tax professional like a CPA or enrolled agent, or the IRS Free File program if you meet income limits.

Paper returns take much longer. The IRS estimates 4 to 6 weeks to process a mailed return, and that is only if everything is filled out correctly. Any errors or missing information can add weeks more. You mail paper returns to an address that depends on your state and whether you are including a payment — the IRS website lists the correct address for your situation.

If you owe taxes, e-filing lets you pay electronically through the IRS website or your tax software, and you can set up a payment plan if you cannot pay in full. Paper filers can still pay online even if they mail their return, which is usually faster than waiting for the IRS to bill you.

The IRS Free File program and low-income filers

The IRS Free File program offers free tax software to people earning below a certain income threshold. The threshold changes yearly — for 2024 returns, it was $79,000 in adjusted gross income, and the 2025 threshold will be announced by the IRS before filing season opens. If you may have access to, you can use brand-name tax software at no cost through the IRS Free File website.

Free File is not the same as free tax preparation. Free File gives you software; you still enter your own information and file yourself. If you want a tax professional to prepare your return for free, look for Volunteer Income Tax information (VITA) sites, which are run by nonprofits and the IRS in your community. VITA serves people earning under $64,000 and offers in-person or remote help.

Even if you do not meet the Free File income limit, many tax software companies offer free versions for straightforward returns — usually if you have only W-2 income and take the standard deduction. Check the software's website before you buy.

What happens if you file early versus late

Filing early in the season has advantages. The IRS processes returns in the order they are received, so early filers get their refunds sooner — often within 21 days of e-filing. Early filing also gives you time to fix any errors before the important date. If the IRS rejects your return because of a problem, you have months to correct it and resubmit.

Filing late — close to April 15 — means you risk missing the important date entirely if you run into problems. If your return is rejected for any reason, you have very little time to fix it and resubmit. You also lose the advantage of getting your refund early, which matters if you are counting on that money.

If you cannot file by April 15, you can request an automatic extension through Form 4868. This extends your filing important date to October 15, 2026. However, the extension is only to file, not to pay. If you owe taxes, they are due on April 15 regardless. Filing an extension late or not at all results in penalties and interest on any unpaid taxes.

Common reasons the IRS rejects returns

The IRS rejects returns for specific, fixable reasons. The most common are a mismatched Social Security number (yours or a dependent's), a duplicate return (you filed twice by accident), income reported on your return that does not match what your employer or bank reported to the IRS, or a missing signature or required information. Electronic filing catches many of these errors before you submit, which is another advantage of e-filing.

If your return is rejected, the IRS sends you a notice explaining why. You then correct the error and resubmit. This process can take weeks, which is why filing early matters — you have time to fix problems without rushing toward the important date.

Identity theft and fraud also cause rejections. If someone files a return using your Social Security number before you do, the IRS will reject your legitimate return. If this happens, contact the IRS directly and file Form 14039 (Identity Theft Affidavit). The IRS has a dedicated identity theft unit and can help you resolve this, but it takes time.

State tax returns and filing important date

Your state tax return important date is usually the same as the federal important date — April 15, 2026 — but a few states have different dates. Check your state's tax agency website to confirm. Some states do not have an income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming), so you only file federal.

If you file your federal return electronically, you can often file your state return through the same software at no extra cost. Some states also offer free filing programs similar to the IRS Free File. Your state tax agency website lists the options available to you.

If you live in one state but work in another, you may owe taxes to both. This is common for people who live near state borders or work remotely for a company in a different state. Your tax software or a tax professional can help you figure out which states you owe and how to avoid paying twice on the same income.

Frequently Asked Questions

Can I file my 2025 return before January 27?

No. The IRS will not accept 2025 returns before January 27, 2025. If you try to file early through tax software, it will be rejected. You can prepare your return ahead of time and have it ready to submit on January 27, but you cannot submit it before then.

What if I do not have all my documents by January 27?

You can file without every document if you have your main income documents (W-2s and any 1099s). If a document arrives after you file, you can file an amended return using Form 1040-X. This adds time, so it is better to wait if possible, but it is not a barrier to filing.

How long does it take to get a refund after I file electronically?

The IRS estimates 21 days for refunds from e-filed returns when you choose direct deposit to your bank account. Some refunds arrive faster, and some take longer if the IRS needs to review your return. Mailed refunds take 4 to 6 weeks or longer.

Do I need to file if I did not earn much income?

It depends on your income and filing status. The IRS sets a threshold below which you do not have to file. For 2024, a single person under 65 did not have to file if their income was under $14,600. The 2025 threshold will be slightly higher. Check the IRS website or use the IRS Interactive Tax Assistant to see if you must file.

What if I owe taxes and cannot pay by April 15?

You can set up a payment plan with the IRS. File your return on time even if you cannot pay the full amount. You can then request a short-term extension (up to 120 days) or a long-term installment agreement through the IRS website or by calling the IRS. Penalties and interest accrue on unpaid taxes, but a payment plan is better than not filing at all.
