Over 1.1 Million Americans Risk Losing IRS Refunds Worth More Than $1 Billion in 2025

Every year, billions of dollars in unclaimed tax refunds remain in the hands of the IRS, waiting for taxpayers to claim them. These refunds often go uncollected because people fail to file returns, make errors in their filings, or have never receive checks due to outdated addresses. In 2025 alone, more than $1 billion tied to 2021 tax year returns is still available, affecting over 1.1 million Americans.

There are many factors that lead to unclaimed refunds. Some Americans believe they don’t need to file taxes because their income falls below the filing threshold, while others simply overlook refundable credits like the Earned Income Tax Credit or the Child Tax Credit. Clerical oversights, such as employees entering the wrong bank details, can also stall refunds. Whatever the cause, taxpayers have just three years from the original filing deadline to claim what they’re owed before the funds are permanently transferred to the U.S. Treasury.

This slideshow covers the tools provided by the IRS to help individuals track down their unclaimed money. Learn about the “Where’s My Refund?” portal, as well as how to amend returns and find change of address forms. We even detail how heirs can recover funds owed to deceased family members. Learn the rules, deadlines, and steps involved to prevent missed opportunities and ensure your money doesn’t disappear into the hands of the government forever.
