Interest on refunds represents an important aspect of the U.S. tax system designed to compensate taxpayers when the IRS delays issuing their federal tax refund. Typically, taxpayers expect their refunds within about 21 days after filing their tax returns. However, delays can occur due to processing backlogs, errors on returns, or additional reviews. When refunds take longer than 45 days after the original filing deadline or the date you filed (whichever is later), the IRS is required by law to pay interest on the amount of the refund.
Background and Purpose
This interest payment policy exists to protect taxpayers from losing the time value of their money. When you overpay taxes, the IRS holds funds that rightfully belong to you during the refund processing period. The interest ensures fairness by providing compensation if the IRS does not return your money promptly. This practice also encourages the IRS to process refunds efficiently.
How Interest on Refunds Works
The interest starts accruing after 45 days from the tax filing deadline (usually April 15) or the date you filed your return if you filed late. The IRS pays interest from that point until the refund is finally sent. For example, if you file on April 15 and your refund arrives on July 1, you are entitled to interest on the refund amount from May 30 onward (45 days after April 15) until July 1.
The interest rates are set quarterly and tied to Treasury bill rates plus a margin, varying over time. For instance, in 2024, rates for individuals ranged between 5% and 5.5% annually in recent quarters. The IRS reports this interest on Form 1099-INT, which you must include as taxable income on your next tax return.
Who Can Receive Interest on Refunds?
Any individual, family, or business expecting a federal tax refund may qualify for interest if the IRS delays payment beyond the 45-day threshold. This ensures equitable treatment regardless of the refund size.
Strategies to Avoid Delays and Interest Payments
- File Early and Accurately: The sooner you file, the sooner the IRS starts processing, reducing the chance of delays. Accuracy helps prevent errors that can slow processing.
- Use IRS Tools: Track your refund status with the IRS “Where’s My Refund?” tool to stay informed about potential delays.
- Keep Documentation: If you receive interest, retain Form 1099-INT for accurate tax reporting.
Common Misconceptions
- Interest is paid only after 45 days, not just a few days of delay.
- The interest amount is generally small because most refunds are processed within the standard timeline.
- IRS interest payments are taxable income and must be reported on your tax return.
Frequently Asked Questions

Q: Does late filing impact interest?
A: Yes, the 45-day countdown starts on the later of the tax filing deadline or the date you actually submit your return, so late filing delays when interest begins.
Q: How common is it to receive interest on refunds?
A: It’s relatively uncommon because the IRS usually issues refunds within the 21-day target unless issues arise.
