Tax season 2025 officially begins January 27
The IRS will start accepting and processing tax returns on Monday, January 27, 2025. This is when the agency's systems open to receive both paper and electronic filings. If you file electronically, you can submit your return as soon as that date arrives. Paper returns can be mailed anytime, but the IRS won't process them until after January 27.
The filing deadline itself is Tuesday, April 15, 2025. That's the last day to file your 2024 tax return or request an extension. If you miss April 15 without an extension, you'll face penalties and interest on any taxes owed, even if you're due a refund.
The IRS chose January 27 as the start date because it needed time to update its systems after the 2024 tax year ended on December 31. The agency also waits for W-2 forms and 1099 forms to arrive from employers and financial institutions — those documents are due to the IRS by January 31, 2025.
Key Takeaways
- You can file your 2024 return starting January 27, 2025, either electronically or by mail.
- The deadline to file or request an extension is April 15, 2025; missing this date triggers penalties and interest.
- W-2 and 1099 forms from employers and financial institutions arrive by January 31, so you'll have those documents before filing opens.
- If you file electronically, refunds typically arrive within 21 days; paper returns take longer to process.
Why the IRS waits until late January to open
The IRS doesn't open on January 1 because it needs time to reprogram its systems for the new tax year. Tax law changes every year — deduction amounts shift, tax brackets adjust for inflation, and new forms are created. The agency also has to coordinate with employers and financial institutions to ensure W-2s, 1099s, and other income documents are ready.
Employers must send W-2 forms to employees by January 31 and file copies with the IRS by the same date. If the IRS opened before then, you'd file without knowing your actual income from your job. The same applies to 1099 forms from banks, investment firms, and freelance payment platforms — they're due January 31 as well. Starting January 27 gives you a few days to collect these documents before you file.
When you'll receive your refund
If you file electronically and choose direct deposit, the IRS typically issues refunds within 21 days. That means if you file on January 27, you could see money in your bank account by mid-February. Paper returns take much longer — the IRS estimates 4 to 6 weeks to process them and issue a refund.
The 21-day timeline assumes your return is complete and accurate. If the IRS finds errors or needs to verify information, the process takes longer. You can track your refund status using the IRS's "Where's My Refund?" tool on irs.gov starting 24 hours after you file electronically, or 4 weeks after you mail a paper return.
What documents you need before January 27
Gather these documents before tax season opens so you're ready to file immediately:
- W-2 forms from each employer (one for each job you held in 2024)
- 1099 forms for interest, dividends, freelance income, or other non-wage income
- Mortgage interest statement (Form 1098) if you own a home
- Student loan interest statement (Form 1098-E) if you paid student loan interest
- Receipts or records of charitable donations if you itemize deductions
- Medical expense records if you're claiming medical deductions
- Last year's tax return for reference
Employers and financial institutions will mail these forms or make them available online by January 31. If you don't receive a W-2 or 1099 by early February, contact the employer or institution directly — they're required to send it. If they still don't, you can file without it and amend your return later, but it's better to wait and file accurately.
Filing options available starting January 27
You have three main ways to file once tax season opens: electronically through tax software, electronically through a tax professional, or by mail with a paper form.
Electronic filing through tax software is the fastest route. You enter your information into programs like TurboTax, H&R Block, or IRS Free File (if your income is below a certain threshold). The software calculates your taxes, checks for errors, and submits your return to the IRS. You get confirmation within minutes. Refunds arrive within 21 days if you choose direct deposit.
Filing through a tax professional — a CPA, enrolled agent, or tax preparer — means someone else handles the filing for you. They'll ask for your documents, prepare your return, and file it electronically. This costs money but is useful if your situation is complex (self-employment income, rental property, multiple states). Refunds still arrive within 21 days if direct deposit is used.
Paper filing means printing Form 1040 and any schedules you need, filling them out by hand, and mailing them to the IRS address for your state. The IRS won't process paper returns until after January 27, and refunds take 4 to 6 weeks. Use this option only if you can't file electronically.
What happens if you miss the April 15 deadline
If you don't file by April 15, 2025, and you don't have an extension, the IRS charges a failure-to-file penalty. The penalty is usually 5% of the unpaid tax for each month your return is late, up to 25%. You'll also owe interest on any taxes owed, calculated daily from the original due date.
If you're due a refund and you file late, you don't face a penalty — but you lose the refund if you wait more than three years. The IRS keeps unclaimed refunds after that period.
You can request an automatic six-month extension by filing Form 4868 by April 15. This moves your deadline to October 15, 2025. The extension gives you more time to file, but it does not extend the time to pay taxes owed. If you owe money, you still need to pay by April 15 to avoid interest and penalties, even if you file the extension.
Frequently Asked Questions
Can I file before January 27?
No. The IRS's systems don't accept returns before January 27, 2025. If you try to file electronically before that date, your software will reject it. Paper returns can be mailed anytime, but the IRS won't process them until after January 27.
What if I don't have all my documents by January 27?
Wait until you have them. Filing without a W-2 or 1099 means your return is incomplete and may be rejected or delayed. If a document arrives after you file, you can file an amended return (Form 1040-X) once you have the correct information.
Do I have to file if I didn't earn much money?
It depends on your income and filing status. The IRS sets a threshold each year — if your income is below it, you're not required to file. However, if taxes were withheld from your paychecks, filing gets you a refund. Check the IRS website for 2024 income thresholds based on your age and filing status.
Will tax season 2025 be different from 2024?
Yes. Tax brackets, standard deduction amounts, and some credits change every year for inflation. The IRS also updates forms and rules. Your tax software will include all 2024 changes automatically, so you don't need to track them yourself.
What if I owe taxes instead of getting a refund?
You still need to file by April 15, 2025. If you can't pay the full amount, the IRS offers payment plans. You can set up a short-term plan (120 days or less) or a long-term installment agreement. Interest and penalties apply to unpaid taxes, so paying as soon as possible costs you less.
