Unclaimed and Undelivered IRS Tax Refunds: How to Claim What You're Owed

Every year a large amount of refund money is never collected, and most of it belongs to people who simply did not file.

Refunds also go undelivered for ordinary reasons: an address that changed, a bank account that closed, a cheque that never arrived. Both situations are fixable, and both are subject to a window after which the money stays where it is.

This covers why refunds go unclaimed, the deadline that applies, how to claim one that was issued but never arrived, how to claim one for a year you never filed, and how to stop it happening again.

The Scale of Unclaimed Refunds

Each year, the IRS announces that hundreds of millions of dollars in tax refunds go unclaimed or undelivered. The IRS estimates that over one million taxpayers may be owed refunds in any given year simply because they failed to file a return or had a mailing problem.

There is a hard deadline: the IRS holds unclaimed refunds for three years from the original filing deadline. After that, the money is forfeited to the US Treasury permanently.

Common Reasons Refunds Go Unclaimed or Undelivered

• Wrong mailing address on file with the IRS
• Bank account closed or incorrect account/routing number
• Paper check returned as undeliverable by postal service
• Taxpayer moved without notifying the IRS
• Taxpayer did not file a return for a year they were entitled to a refund
• Deceased taxpayer with no one claiming the refund

The Three-Year Rule: Critical Deadline

To claim a refund, you must file your original return within three years of the original due date (including extensions). Example:

• Tax year 2021 return due April 18, 2022
• If you never filed and are owed a refund, you had until April 18, 2025
• After that deadline, the refund is permanently lost to the Treasury
• This is a hard cutoff, the IRS has no discretion to extend it

How to Claim an Undelivered Refund

• Check IRS.gov 'Where's My Refund?' tool, confirms whether the refund was issued
• If the check was returned to the IRS, your refund is on hold pending an updated address
• Update your address by filing Form 8822 (Change of Address) with the IRS
• Call the IRS at 1-800-829-1040 to request a replacement check
• For direct deposit failures (wrong account), the bank typically rejects and returns funds to the IRS; then a paper check is issued to your address on file

Pro Tip: Always update your address with the IRS after a move. Form 8822 is a one-page form mailed to the IRS service center for your state.

How to Claim an Unclaimed Refund (Never Filed the Return)

• Gather all income documents for that year (W-2s, 1099s, employers and financial institutions keep these on file for years)
• File the original return for that year (you can still file past-due returns; there is no penalty for filing late when you are owed a refund)
• Mail the return; paper filing is required for older years if e-filing is no longer available for that year
• The IRS will process the return and issue your refund (within the three-year window)
• If the IRS already assessed a balance for that year, your refund may be applied to offset the balance

State Unclaimed Tax Refunds

State tax authorities have similar unclaimed refund issues. After a certain period, unclaimed state tax refunds may be transferred to the state's unclaimed property fund.

• Search your state's unclaimed property database (all states have one; search at missingmoney.com or your state comptroller's website)
• Contact your state's department of revenue directly to inquire about specific refund status
• Each state has different holding periods (typically 1-5 years) before funds transfer to unclaimed property

Preventing the Problem: Best Practices

• Use direct deposit for all tax refunds, eliminates mailing errors
• Update your address with the IRS immediately after moving (Form 8822)
• Keep your bank account information current if you move accounts
• File every year you have earned income, even if you think you do not owe, you may be owed a refund
• Use the IRS 'Get Transcript' tool to see what the IRS has on file for prior years
