Tax refund season officially begins when the IRS starts accepting returns
The IRS opens its filing season each year on a specific date set months in advance. For the 2024 tax year, the IRS began accepting returns on January 29, 2024. For 2025 tax returns, filing season opens January 27, 2025. The IRS announces the opening date in the fall of the previous year, so you can plan ahead.
The opening date matters because the IRS cannot process your return before that date, even if you file earlier. If you submit your return on January 15 when the season doesn't open until January 27, the IRS will hold it and begin processing on the official start date. This means filing early does not speed up your refund if you file before the season opens.
Most people file between late January and mid-April, when the April 15 deadline approaches. However, if you expect a refund rather than owing taxes, you can file any time during the year without penalty. Filing early in the season—once it opens—typically means your refund arrives sooner, because the IRS processes returns in the order they are received.
Key Takeaways
- The IRS announces its filing season opening date in the fall, and you cannot file before that date even if you prepare your return early.
- Filing as soon as the season opens gives your return a place earlier in the processing queue, which can speed up your refund.
- If you expect a refund, you can file anytime during the year without penalty, but filing closer to April 15 means a longer wait for your money.
- The IRS processes returns in the order received, so timing your submission affects when the agency reaches your return.
Why the IRS sets a specific opening date each year
The IRS uses the weeks before filing season to prepare its systems, train staff, and test the technology that processes millions of returns. The agency also coordinates with state tax agencies and the tax software industry to ensure systems can handle the volume. This preparation takes time, which is why the season does not open on January 1.
The opening date also gives the IRS time to incorporate changes to tax law that took effect in the previous year. Tax code changes sometimes happen in December or early January, and the IRS must update its systems to reflect those changes before accepting returns. Filing before the IRS has made these updates can cause your return to be rejected or delayed.
How filing early in the season affects your refund timeline
The IRS processes returns in the order they arrive, with some exceptions for complex returns that require manual review. If you file on February 1 and someone else files on March 15, your return reaches the front of the line first. This means you will typically receive your refund sooner if you file early in the season.
However, filing early does not may provide a fast refund if your return has errors or requires verification. The IRS may hold your return for identity verification, income matching, or other checks. These holds can add weeks or months to your timeline, regardless of when you filed. You can check your refund status using the IRS Where's My Refund tool, which updates every 24 hours after your return is accepted.
The IRS typically issues refunds within 21 days of accepting your return if you file electronically and choose direct deposit. Paper returns take longer—usually 4 to 6 weeks. Filing early in the season increases the chance that your 21-day window falls before the April 15 deadline rush, when processing times can stretch longer.
State tax refund season and how it differs from federal
Most states open their tax filing season on the same date as the IRS or shortly after. However, some states have their own opening dates. For example, a few states may not accept returns until February even if the IRS opens in late January. Check your state's tax agency website to confirm when you can file your state return.
State refunds are processed separately from federal refunds, so you may receive them at different times. A state may issue your refund in 2 to 3 weeks while your federal refund takes longer, or vice versa. If you file both federal and state returns together, the state will hold your return until the IRS accepts the federal version, which can add a few days to the state processing timeline.
What to do if you file before the season opens
If you prepare your return before the IRS opens filing season, you have two options: hold the return and submit it after the season opens, or submit it early and let the IRS hold it until processing begins.
Submitting early has one advantage: the IRS will accept and time-stamp your return on the date you file, even if processing does not begin until the season opens. This means your return is officially "in line" before other returns filed on the opening day. However, the IRS will not actually process your return or issue your refund until after the season opens, so the time-stamp advantage is small.
The safer approach is to file after the season officially opens. This avoids any risk of your return being rejected due to system updates or tax law changes that have not yet been incorporated into the IRS systems. Once the season opens, the IRS systems are fully ready, and your return will move through processing immediately.
How to track your refund once you file
After you file electronically, the IRS sends you a confirmation number. Keep this number—you will need it to check your refund status. The IRS Where's My Refund tool (available at irs.gov) lets you enter your Social Security number, filing status, and refund amount to see where your return stands.
The tool updates every 24 hours and shows one of three statuses: "Return Received" (the IRS has your return but has not finished processing), "Approved" (the IRS has approved your return and is preparing your refund), or "Sent" (your refund has been issued). If your refund is being mailed, the tool will give you an expected delivery date. If you chose direct deposit, the tool will show the deposit date.
If your return shows no status after 24 hours, wait another day and check again. The system updates overnight, and it can take a few days for newly filed returns to appear in the tool. If your return does not appear after a week, contact the IRS at 1-800-829-1040.
Common delays that push refunds past the typical timeline
Even if you file early in the season, your refund may take longer than 21 days if the IRS needs to verify information on your return. The most common triggers for delays are mismatched income (your W-2 or 1099 does not match what you reported), missing or incorrect Social Security numbers, or duplicate claims for the same dependent.
Identity theft and fraud checks also delay refunds. If the IRS suspects your return may be fraudulent, it will hold the refund while it verifies your identity. This can add 2 to 4 weeks to your timeline. The IRS will contact you by mail if this happens, and you may need to provide additional documents to prove your identity.
Claiming certain credits—like the Earned Income Tax Credit or Child Tax Credit—can also trigger additional review, especially if your income is near the phase-out threshold. These reviews are routine but add processing time. The IRS publishes a list of returns that typically require extra review, and you can check whether your situation matches before you file.
Frequently Asked Questions
Can I file my taxes before the IRS opens filing season?
You can prepare your return before the season opens, but the IRS will not accept it until the official opening date. If you submit it early through tax software, it will be rejected or held until the season begins. It is safer to wait until the season opens to file.
Does filing on the first day of tax season may provide a faster refund?
Filing on the first day puts your return earlier in the processing queue, which usually means a faster refund. However, if your return requires verification or additional review, the timing advantage disappears. The IRS processes returns in order, but complex returns may be set aside for manual review regardless of when they were filed.
What is the difference between when the IRS opens and when I can file my state taxes?
Most states open their filing season on the same date as the IRS or within a few days. A few states have later opening dates. Check your state's tax agency website to confirm. State refunds are processed separately and may arrive before or after your federal refund.
If I file in March instead of February, will my refund take much longer?
Filing in March rather than February typically adds 1 to 2 weeks to your refund timeline, since the IRS processes returns in order. However, if you file in late March or early April, you risk your refund arriving after April 15, when processing times can stretch due to the deadline rush.
What should I do if the IRS Where's My Refund tool shows no status for my return?
The tool updates every 24 hours, so wait at least one day and check again. Newly filed returns can take a few days to appear. If your return does not show up after a week, contact the IRS at 1-800-829-1040 with your confirmation number.
