Tax season 2025 officially begins January 27
The Internal Revenue Service (IRS) begins accepting and processing tax returns on Monday, January 27, 2025. This is the earliest date you can file your 2024 tax return. The filing important date is Tuesday, April 15, 2025 — the standard date unless it falls on a weekend or federal holiday, which it does not in 2025.
The delay from January 1 to late January exists because the IRS needs time to receive and process Forms W-2 and 1099 from employers and financial institutions. Employers must send W-2s to employees by January 31, and most 1099 forms must arrive by the same date. The IRS waits a few days after that important date to may support their systems have received the documents before opening the filing window.
You can file before January 27 if you want — tax software will let you prepare your return — but the IRS will not accept it electronically or process it until that date. If you mail a paper return before January 27, it will sit in a processing queue until the season opens.
Key Takeaways
- The IRS begins accepting returns on January 27, 2025, and the filing important date is April 15, 2025.
- Filing early (as soon as January 27) reduces the risk of identity theft and gets your refund faster if you are owed one.
- You can prepare your return before January 27, but the IRS will not process it until the season officially opens.
- If you owe taxes, filing early does not change when payment is due, but paying by April 15 avoids penalties and interest.
Why the IRS waits until late January to open
Tax season does not start on January 1 because employers and financial institutions need time to compile and send tax documents. A W-2 form requires your employer to report your wages, withholding, and other compensation for the entire year. A 1099 form — used for freelance income, investment earnings, or other non-wage income — requires the payer to report what they sent you. These forms must be mailed or filed with the IRS by January 31.
If the IRS opened on January 1, millions of returns would be filed with incomplete or missing information. The IRS would then have to contact filers to correct errors, slowing down refunds and creating confusion. By waiting until late January, the agency ensures that most W-2s and 1099s have arrived in their system, so returns can be processed more smoothly.
The exact opening date can shift by a day or two from year to year depending on the IRS's processing schedule and staffing. The agency announces the date in early December of the prior year. For 2025, January 27 was announced in December 2024.
What happens between January 27 and April 15
Once the IRS begins accepting returns on January 27, you have 2.5 months to file. During this period, the IRS processes returns in the order they are received — not all at once on April 15. If you file in late January or early February and your return is straightforward, you may receive a refund within two to three weeks. If you file in late March or early April, processing takes longer because the IRS is handling millions of returns simultaneously.
The April 15 important date applies to everyone, regardless of when you file. If you do not file by April 15 and you owe taxes, you face a failure-to-file penalty (usually 5 percent of the unpaid tax per month, up to 25 percent) plus interest on the unpaid amount. If you are owed a refund, there is no penalty for filing late, but you lose the refund if you do not file within three years.
If you need more time, you can request an automatic extension by filing Form 4868 by April 15. This gives you until October 15 to file your return, but it does not extend the important date to pay taxes you owe. If you owe and do not pay by April 15, interest and penalties begin accruing even if your extension is approved.
Filing early versus waiting until later
Filing as soon as the season opens — in late January or early February — has real advantages. If you are owed a refund, you receive it faster. The IRS typically issues refunds within 21 days of accepting your return if you file electronically and choose direct deposit. Filing early also reduces the window during which your identity could be stolen and used to file a fraudulent return in your name.
Tax identity theft happens when someone uses your Social Security number to file a return and claim a refund before you do. If you file first, the IRS rejects the fraudulent return. If the thief files first, you may not discover the theft until you try to file weeks later. Filing in late January or early February closes this window quickly.
The main reason to wait is if you are still gathering documents — a late W-2, a 1099 from a client, or records of charitable donations or medical expenses. If you wait until mid-March or later, you risk missing the April 15 important date if complications arise or if the IRS is backlogged.
How to prepare before January 27
You do not have to wait for January 27 to start preparing. Gather your documents now: your 2024 W-2s (when they arrive), any 1099s, receipts for deductions, records of charitable donations, medical expenses, property tax payments, and mortgage interest statements. If you are self-employed, compile your income and expense records.
You can also enter your information into tax software before January 27. Most software will let you prepare your entire return and save it. When January 27 arrives, you straightforward review it and submit. Some software charges a fee to file, while others are free depending on your income level. The IRS Free File program offers free filing through participating software companies if your 2024 income is below a certain threshold (the threshold varies by year and software provider).
If you use a tax professional — a CPA, enrolled agent, or tax preparer — you can meet with them before January 27 to gather information and discuss your situation. They will file your return as soon as the season opens if you want them to.
What to do if you owe taxes
If you expect to owe taxes, filing early does not change when payment is due. You must pay by April 15, 2025, or face penalties and interest. However, filing early gives you time to arrange payment and avoid last-minute scrambling.
You can pay the IRS directly through their website (IRS.gov), by phone, by mail, or through your tax software. You can also set up a payment plan if you cannot pay the full amount by April 15. The IRS offers short-term plans (120 days or less) at no cost and long-term installment agreements that charge a setup fee and monthly interest. Setting up a payment plan before April 15 shows the IRS you are making a good-faith effort to pay, which can reduce penalties.
If you are self-employed or have other income not subject to withholding, you may owe estimated taxes for 2025 as well. Estimated tax payments are due on April 15, June 16, September 15, and December 31. Filing your 2024 return early gives you time to calculate what you might owe in 2025 and plan accordingly.
State tax important date and differences
Most states follow the federal April 15 important date for income tax returns. However, some states have different dates or do not have an income tax at all. Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax. New Hampshire taxes only dividend and interest income, not wages.
A few states have important date that differ slightly from April 15. You should check your state's tax agency website to confirm the important date for your state. If you file a federal extension, most states automatically extend your state filing important date as well, but not all — check before assuming.
Some states also open their filing season on different dates than the IRS. A few states allow filing as early as January 1, while others wait until mid-February. If you file a state return, confirm when your state begins accepting returns.
Frequently Asked Questions
Can I file my 2024 taxes before January 27?
You can prepare your return in tax software before January 27, but the IRS will not accept it electronically until that date. If you mail a paper return before January 27, it will not be processed until the season opens. Filing before the official date does not speed up processing.
What if I do not have all my documents by January 27?
You can file without a late W-2 or 1099 if you have a reasonable estimate of the income. File with what you have, and file an amended return (Form 1040-X) once the missing document arrives. Alternatively, request an extension by filing Form 4868 by April 15 to give yourself more time to gather documents.
Do I have to file by April 15 if I am owed a refund?
There is no penalty for filing late if you are owed a refund, but you must file within three years to claim it. After three years, the IRS keeps the refund. Filing early ensures you do not miss this important date.
What happens if April 15 falls on a weekend or holiday?
In 2025, April 15 is a Tuesday, so the important date is April 15. In years when April 15 falls on a Saturday or Sunday, the important date moves to the following Monday. If April 15 falls on a federal holiday, the important date moves to the next business day. The IRS announces any important date shifts in advance.
Can I file my 2024 return and my 2023 return at the same time?
Yes, if you did not file a 2023 return, you can file both in 2025. File the 2023 return first, then the 2024 return. The IRS will process them separately. If you owe back taxes from 2023, those are due when ready; do not wait until April 15 to pay 2023 taxes.
