A fast-approaching IRS deadline could decide whether many Americans keep or lose the right to seek a possible COVID-era tax refund. Taxpayers who believe they paid penalties or interest tied to late federal tax filings or payments during the pandemic period may need to file a protective refund claim by July 10, 2026.
The deadline matters because the potential refund is connected to Kwong v. United States, a federal court case involving how tax deadlines should have been treated during the national COVID-19 disaster. The case is still being appealed, so no refund is guaranteed. But tax professionals warn that waiting for the appeal to end could be a costly mistake.
What Is the IRS COVID Tax Refund Issue?
The refund question comes from a ruling that suggested certain federal tax filing and payment deadlines may have been automatically suspended during the COVID-19 disaster period. That period ran from January 20, 2020, through May 11, 2023, when the federal COVID emergency was in effect.
If that interpretation ultimately survives appeal, some taxpayers who were charged late-filing penalties, late-payment penalties, estimated tax penalties, or related interest during that window may be able to ask the IRS for money back or request an abatement.
The key point is that taxpayers may need to act before the courts finish deciding the case. A protective claim does not force the IRS to issue a refund now. It simply preserves the taxpayer’s right to seek one later if the legal outcome supports it.
Why July 10, 2026 Is the Date to Watch
Tax professionals say the July 10 deadline is tied to the way refund claim deadlines are calculated. Under the Kwong interpretation, the pandemic-related postponement period effectively ran through July 10, 2023. Since many federal refund claims are subject to a three-year filing window, that makes July 10, 2026 the final date for many taxpayers to protect their claim.
Missing that date could mean losing the right to ask for a refund, even if the courts later rule that the IRS should return certain penalties or interest. That is why tax advisers are treating this as a “file now or risk losing it” situation.
Who May Qualify for a Potential Refund?
The issue may affect a wide range of taxpayers, not just individuals. Potentially eligible groups may include:
- Individual taxpayers
- Small businesses
- Corporations
- Partnerships
- Trusts and estates
- Tax-exempt organizations
The strongest candidates are taxpayers who were assessed or paid IRS penalties or interest connected to returns, payments, or estimated taxes during the COVID disaster period. However, qualification depends on the taxpayer’s account history, the type of tax involved, the timing of payments, and the final result of the Kwong litigation.
How to Protect a Potential Refund Claim
Many taxpayers may need to file IRS Form 843, Claim for Refund and Request for Abatement. In most cases, tax professionals recommend using a separate Form 843 for each tax period and each type of tax involved.
The claim should clearly state that it is a protective claim based on Kwong v. United States and Internal Revenue Code Section 7508A(d). The filing should identify the penalty or interest being challenged and explain that the taxpayer is preserving refund rights while the case remains unresolved.
Taxpayers can review their IRS account transcripts to look for penalty or interest charges from the affected period. Official information about the form is available on the IRS Form 843 page.
Why Certified Mail May Matter
Because the deadline is strict, several tax professionals recommend mailing the protective claim by certified mail before July 10. Certified mail gives taxpayers proof that the claim was sent on time, which may become important if there is later a dispute over whether the IRS received it before the deadline.
Taxpayers who need a preparer, attorney, or other third party to review IRS information should also be aware that authorization forms, such as IRS Form 8821, can take time to process. That makes last-minute preparation riskier, especially for business owners, estates, trusts, or taxpayers with multiple years of IRS activity to review.

Why the IRS Has Not Turned This Into a Refund Program
The IRS has not broadly promoted the deadline because the court fight is not finished. The government is appealing the Kwong ruling, and the agency has not accepted it as final. That means taxpayers should not expect automatic checks or a simple mass-refund process right now.
At the same time, the National Taxpayer Advocate and tax professionals have warned that the filing window could close before the legal questions are settled. That creates an unusual situation: taxpayers may need to file a claim now for a refund that may only become available later.
What Makes This Important for Taxpayers?
The potential impact is large because the COVID disaster period covered more than three years of tax activity. If courts ultimately agree that deadlines were automatically suspended, the decision could affect penalties and interest assessed across individual, business, estate, trust, and nonprofit filings.
For taxpayers, the practical takeaway is not that money is guaranteed. It is that the right to ask for money back may disappear after July 10. Anyone who paid IRS penalties or interest during the COVID emergency period should review their records quickly and consider whether a protective claim is appropriate.
