Key Takeaways:
- Recent court decisions interpreting COVID-19 disaster relief provisions related to tax filing and payment deadlines may affect certain IRS penalties, interest assessments, and refund claims tied to the pandemic period.
- The implications of these rulings are highly technical and depend heavily on a taxpayer’s specific procedural history, payment timing, assessment records, and statute-of-limitations considerations.
- Many practitioners are evaluating whether taxpayers should consider filing protective refund claims before July 10, 2026, while litigation and potential appeals continue.

Recent litigation involving COVID-19 disaster relief provisions tied to tax filing and payment deadlines has created significant discussion within the tax controversy community regarding whether certain IRS procedural deadlines were automatically postponed during the pandemic period.
Two notable cases, Abdo v. Commissioner and Kwong v. United States, interpreted federal tax disaster relief provisions as creating a mandatory postponement period tied to the duration of the federally declared COVID-19 disaster period, plus an additional 60 days.
Under those interpretations, certain procedural periods may have been disregarded from January 20, 2020, through July 10, 2023.
While these rulings have generated substantial interest, the legal and procedural implications remain unsettled. Additional litigation, administrative guidance, and appellate activity are expected, including ongoing developments in matters like Wepplo v. Commissioner. As a result, taxpayers should approach potential refund opportunities cautiously as well as with careful procedural analysis.
Background: COVID-19 Disaster Relief Rules and Ongoing Litigation
Federal tax law generally allows the IRS to postpone certain tax filing and payment obligations for taxpayers affected by federally declared disasters.
During the COVID-19 pandemic, Congress expanded certain disaster relief provisions tied to filing and payment deadlines. Recent court decisions have focused on whether those provisions created a mandatory postponement period that extended throughout the federally declared COVID-19 disaster period, plus an additional 60 days.
In both Abdo v. Commissioner and Kwong v. United States, courts rejected portions of IRS regulatory interpretations that attempted to narrow the scope of those postponement rules and instead applied a plain-language reading of the statute.
The Kwong decision, in particular, involved extensive procedural litigation surrounding refund claim timing, assessment periods, and statutory interpretation. Although the taxpayer prevailed on certain procedural timing issues, the government also prevailed on other aspects of the case, underscoring the narrow and fact-specific nature of these disputes.
Subsequent filings, including the April 2026 motion in Wepplo v. Commissioner, continue to test how courts may apply these interpretations to interest computations and procedural tax controversy matters.
Potential Areas of Impact
Depending on the taxpayer’s procedural history and underlying facts, these developments may affect:
- Penalty assessments
- Interest accrual calculations
- Refund claim timing
- Protective refund claim strategies
- Procedural defenses tied to statute-of-limitations periods
Potentially affected items may include:
- Late-filing penalties
- Late-payment penalties
- Estimated tax penalties
- Underpayment interest
- Certain international information return penalties
- Certain refund and lookback limitation calculations under IRC Section 6511
However, these issues are highly and depend on a taxpayer’s specific facts, including timing of assessments, payments, and open limitation periods.
The viability of any potential claim may depend on numerous factors, including:
- Whether statutes of limitation remain open
- Timing of assessments and payments
- Prior administrative filings
- Existing litigation or Appeals activity
- Whether amounts were paid, abated, transferred, or credited
- How interest computations were calculated
- Whether protective claims were previously filed
Why July 10, 2026, May Matter for You
For many taxpayers, July 10, 2026 may represent an important procedural deadline for preserving potential refund rights associated with the COVID-19 disaster postponement period.
Many practitioners are currently evaluating whether taxpayers should consider filing protective refund claims using IRS Form 843 while litigation continues and before applicable statutes of limitation potentially expire.
However, determining whether a viable claim exists requires more than identifying COVID-period penalties or interest. It requires detailed procedural analysis.
As demonstrated in Kwong and Wepplo, these matters often involve:
- Complex transcript analysis
- Assessment timing review
- Payment application analysis
- Refund litigation procedures
- Interest recomputation methodologies
- Interactions between multiple Internal Revenue Code provisions
Accordingly, taxpayers should not assume these issues can be addressed through standard refund filing approaches or self-prepared claims. Utilizing a professional is your best bet.
Why Professional Analysis Matters Here
The procedural issues raised in these cases are highly technical and continue to evolve rapidly through litigation and administrative interpretation.
Even taxpayers with seemingly similar fact patterns may face materially different outcomes depending on a few different things, like:
- Procedural posture
- Open limitation periods
- Payment histories
- Prior IRS administrative actions
- Existing controversy proceedings
As a result, taxpayers considering whether these developments may affect their positions should consult experienced tax controversy advisors before determining whether and how to proceed.
