Where’s my tax refund? Why this Tax Refund may be delayed
If you’re waiting on a tax refund, the timeline depends on how you filed and whether your return needs extra review; the Internal Revenue Service began accepting 2025 tax year returns on Jan. 26. That timing matters now because filing method, postmark rules and new federal legislation are already shaping how and when refunds move out.
Tax Refund timeline and how to check it
Most refunds are processed far faster for electronic filers: more than 90% of tax returns are filed online each year, totaling over 150 million electronically filed individual income tax returns. The IRS makes a "Where's My Refund?" tool available on IRS. gov so filers can check status after submitting their return. For many filers, the agency says refunds are issued in less than three weeks, but that window depends on whether you filed electronically or by paper.
Why some refunds slow down
Electronic filing generally moves returns through processing more quickly, while paper returns take longer because they must be handled and cut into checks. The IRS lists several common reasons a return can be delayed; one frequent cause is that a return needs further review, which extends processing beyond the typical three-week timeframe. Policymakers are also changing the overall refund picture: refunds are projected to rise in 2026 as a result of the federal tax legislation known as the "One Big Beautiful Bill, " and one estimate puts retroactive tax relief at $91 billion, with $60 billion distributed as refunds and $30 billion offsetting tax liabilities.
Deadlines and what filers should watch
Federal income tax returns for the 2025 tax year must be filed by April 15, 2026. Americans living or traveling outside the U. S. and Puerto Rico on April 15, 2026, receive an automatic two-month extension to file, making the deadline June 15, 2026. Timeliness rules differ by filing method: for electronic filers the deadline is 11: 59 p. m. local time on the due date, and the timestamp in your time zone determines whether the filing is on time. For paper returns, the IRS will consider them on time if they are correctly addressed, have sufficient postage and are mailed and postmarked by the due date.
The IRS also urges taxpayers not to depend on receiving a refund by a specific date when planning major purchases or bill payments, since additional review can push a return beyond typical processing times. The next confirmed milestone for most filers is the April 15, 2026 filing deadline; after that, the pace of refunds will reflect whether returns were filed electronically or by paper and whether any returns require further review.
