Kwong v. United States
Background
In November 2025, the U.S. Court of Federal Claims issued its decision in Kwong v. United States, 179 Fed. Cl. 382, holding that the 2019 version of IRC § 7508A(d) created a mandatory postponement period running from January 20, 2020 through July 10, 2023 — and that this period extended the two-year deadline for filing a federal tax refund suit. Practitioners and the National Taxpayer Advocate have identified July 10, 2026 as the deadline by which affected taxpayers must file a protective claim to preserve their rights under IRC § 6511. The Department of Justice filed a notice of appeal to the Federal Circuit on May 15, 2026; the law remains unsettled.
Circulating guidance in the tax professional community has, in some cases, materially overstated the scope of the Kwong holding or mischaracterized the applicable legal authority. This package is designed to provide EROs with accurate, legally defensible tools for evaluating and, where appropriate, filing protective claims on behalf of eligible clients — while protecting both clients and EROs from the risks associated with improperly framed claims.
How to Use This Package
Package Contents
| Exhibit | Document | Purpose |
|---|---|---|
| Exhibit A | Eligibility & Preparation Checklist | Complete before filing any claim. Screens for eligibility, identifies required information, documents disqualifying factors, and confirms client disclosure. |
| Exhibit B | Protective Claim Letter Template | Cover letter to accompany Form 843, submitted to the IRS by the ERO on behalf of the taxpayer. Establishes the legal basis for the protective claim under IRC § 7508A(d) and (f) and Kwong v. United States, and requests that the IRS hold the claim in suspense pending resolution of the Federal Circuit appeal. Replace all bracketed fields with client-specific information before filing. |
| Exhibit C | Sample Form 843 — Corrected Template | An annotated sample showing the correct checkbox selections, IRC sections, and Line 8 explanation for a Kwong-based protective claim. File one Form 843 per tax year, listing all applicable penalties and interest for that year. Complete with client-specific information. |
Important: Complete ALL parts of this checklist before filing a protective claim. A separate checklist is required for each tax year being evaluated. Do not combine multiple tax years on a single Form 843.
Answer each question YES or NO for the specific penalty or interest amount being evaluated. Each question must be answered YES to proceed. If any answer is NO, the client does not qualify for a Kwong protective claim for this penalty and tax year but may qualify for other relief.
| Eligibility Question | YES | NO |
|---|---|---|
| 1. The specific penalty or interest being claimed relates to a federal income tax filing or payment obligation with a due date that fell between January 20, 2020 and July 10, 2023 (the § 7508A(d) mandatory postponement window).
► If NO: The obligation at issue falls outside the postponement window, and Kwong does not apply. Note: Tax year 2023 returns with a standard April 15, 2024 due date are not eligible. The client may qualify for other penalty relief — see Part III for alternatives.
|
☐ YES | ☐ NO |
| 2. The IRS assessed a penalty or underpayment interest against the client that is directly related to the obligation identified in Question 1.
► If NO: There is no assessed amount to claim for this tax year and penalty type. No further action needed on a Kwong claim.
|
☐ YES | ☐ NO |
| 3. The penalty or interest identified above has been paid by the client — not merely assessed and unpaid.
► If NO: A refund claim under § 6511 requires a paid amount. A Kwong protective claim is not available for unpaid assessments. However, the client may be eligible for a penalty abatement request, which follows a different procedure and does not require prior payment.
|
☐ YES | ☐ NO |
| 4. The payment identified above was made on or after July 10, 2020, or within three years of the date this claim is being filed, whichever is later.
► If NO: The payment may fall outside the § 6511 lookback window. Do not file a Kwong protective claim. Note: this situation will be rare — most COVID-era penalty payments will satisfy this requirement.
|
☐ YES | ☐ NO |
| 5. Today's date is on or before July 10, 2026 — the protective filing deadline based on the Kwong reasoning, measured as three years from the extended § 7508A(d) deadline of July 10, 2023.
► If NO: The protective filing deadline has passed, and a Kwong claim is time-barred for this client. Do not file.
|
☐ YES | ☐ NO |
A. Tax Year Postponement Window Reference
| Tax Year | Standard Due Date | IRS-Issued Extension | In § 7508A(d) Window? | Prior IRS Relief |
|---|---|---|---|---|
| 2019 | April 15, 2020 | July 15, 2020 (Notice 2020-17) | ✓ YES | Notice 2020-17; Notice 2022-36* |
| 2020 | April 15, 2021 | May 17, 2021 (Notice 2021-21) | ✓ YES | Notice 2021-21; Notice 2022-36* |
| 2021 | April 18, 2022 | None Issued | ✓ YES | None |
| 2022 | April 18, 2023 | None Issued | ✓ YES — due date fell before May 11, 2023 end of declaration | None |
| 2023 | April 15, 2024 | N/A | ✗ NO — due date falls after July 10, 2023 | N/A |
* Notice 2022-36 provided automatic penalty relief for certain late-filed 2019 and 2020 returns. Verify whether this relief was already applied to the client's account before filing a Kwong claim for those years.
Note: The § 7508A(d) postponement window runs from January 20, 2020 through July 10, 2023. The IRS-issued extensions shown above are separate administrative actions and may have already resolved some penalties for 2019 and 2020 filers.
B. Identify Each Penalty and Interest Amount at Issue
List each separate penalty or interest charge at issue for this tax year. File a separate Form 843 for each tax year.
| Penalty / Interest Type | IRC Section | Amount Assessed ($) | Date Paid | Amount Paid ($) |
|---|---|---|---|---|
| Failure-to-File Penalty | § 6651(a)(1) | |||
| Failure-to-Pay Penalty | § 6651(a)(2) | |||
| Underpayment (Est. Tax) | § 6654 | |||
| Underpayment Interest | § 6601 | |||
| Other (specify below) |
Filing a Kwong claim for penalties already resolved, abated, or the subject of prior IRS action wastes administrative resources and may cause complications. Verify each item below before filing.
| Prior Relief / Disqualifying Factor | YES | NO |
|---|---|---|
| 1. Were any of the penalties at issue already abated under IRS Notice 2022-36 (automatic COVID relief for 2019/2020 late filers)?
► If YES: Those specific penalties are already resolved. Remove from this claim. Verify on account transcript.
|
☐ YES | ☐ NO |
| 2. Has the client previously received First-Time Abatement (FTA) under IRM 20.1.1.3.6 for any of the same penalties?
► If YES: Those penalties have already been abated. Do not include in this claim.
|
☐ YES | ☐ NO |
| 3. Is there a currently open IRS examination, audit, or Appeals proceeding for the same tax year?
► If YES: Do not file this claim without additional consideration. Filing may interact with the open proceeding.
|
☐ YES | ☐ NO |
| 4. Is there an active Tax Court petition, refund suit, or other litigation involving the same tax year?
► If YES: Stop. Do not file this claim without additional consideration. Filing a refund claim during active litigation may be procedurally improper.
|
☐ YES | ☐ NO |
| 5. Has the IRS previously denied a refund claim for these same penalty amounts?
► If YES: Determine whether the prior denial is now final. If the two-year suit period under § 6532 has not expired, a refund suit may be appropriate.
|
☐ YES | ☐ NO |
| 6. Are the penalties at issue covered by an existing Installment Agreement, OIC, or other IRS resolution agreement?
► If YES: Filing this claim may have implications for the existing agreement. Do not file this claim without additional consideration.
|
☐ YES | ☐ NO |
| 7. Has the client already filed a Form 843 protective claim for these same amounts for this tax year?
► If YES: Do not file a duplicate. Track the pending claim and monitor for IRS action or disallowance notice.
|
☐ YES | ☐ NO |
A protective claim preserves the client's rights but does not guarantee a refund. Given that the IRS has appealed Kwong and will likely deny or hold these claims, the cost of preparation and filing should be weighed against the potential recovery.
A. Dollar Threshold Analysis
| Assessment Question | YES | NO |
|---|---|---|
| Is the total potential recovery (penalties + interest at issue) greater than $500?
► If NO: The cost of preparation may exceed the potential recovery. Consider whether filing is in the client's best interest and document your analysis.
|
☐ YES | ☐ NO |
| Has the client been informed that the IRS will likely deny or hold this claim and that recovery may take years, if at all?
► If NO: This disclosure must be made before filing. See Part VI — Client Disclosure.
|
☐ YES | ☐ NO |
B. Total Potential Recovery
| Item | Amount ($) |
|---|---|
| Total failure-to-file penalties paid (§ 6651(a)(1)) | $ |
| Total failure-to-pay penalties paid (§ 6651(a)(2)) | $ |
| Total underpayment penalties paid (§ 6654) | $ |
| Total underpayment interest paid (§ 6601) | $ |
| Other (specify) | $ |
| Total Potential Recovery | $ |
Confirm each item is complete before the Form 843 is submitted. A separate Form 843 must be filed for each tax year.
Each of the following disclosures must be made to the client before filing. Check each box to confirm the disclosure was made, and the client understood.
After completing all parts, check ONE box below to document your determination. Attach this completed checklist to the client file regardless of outcome.

Re: Protective Claim for Refund and Request for Abatement — COVID-Era Penalties and Interest
Tax Year: [ENTER SPECIFIC TAX YEAR]
Authority: IRC §§ 7508A(d) (2019), 7508A(f) (P.L. 119-64); Kwong v. United States, 179 Fed. Cl. 382 (Nov. 25, 2025)
Dear Sir or Madam:
I am submitting the enclosed Form 843 to request a refund and/or abatement of [failure-to-file penalty (§ 6651(a)(1)) / failure-to-pay penalty (§ 6651(a)(2)) / underpayment interest (§ 6601), or other applicable penalty] assessed for the tax year above. This is a protective claim filed to preserve my rights under the statute of limitations pending the outcome of ongoing litigation.
Legal Basis
In Kwong v. United States, 179 Fed. Cl. 382 (Nov. 25, 2025), the U.S. Court of Federal Claims held that the 2019 version of IRC § 7508A(d) created a mandatory postponement period running from January 20, 2020 through July 10, 2023 (60 days after the COVID-19 disaster declaration closed on May 11, 2023), and extended the refund suit deadline under IRC § 6532(a) accordingly. Additionally, IRC § 7508A(f), enacted as part of P.L. 119-64 (Dec. 26, 2025), provides that the § 7508A(d) postponement is treated as a filing extension for purposes of the § 6511(b)(2)(A) refund lookback period.
The penalties and interest identified on the enclosed Form 843 accrued during the January 20, 2020 – July 10, 2023 postponement window. Consistent with the Kwong holding, the taxpayer submits that these amounts may have been erroneously assessed and requests that they be refunded or abated.
Why This Claim Is Filed Now
The Department of Justice filed a notice of appeal on May 15, 2026. Under the Kwong reasoning, the three-year limitation period under IRC § 6511(a) — measured from the extended deadline of July 10, 2023 — closes on July 10, 2026. The National Taxpayer Advocate has confirmed July 10, 2026 as the protective filing deadline for most affected taxpayers. This claim is filed now to preserve the taxpayer's rights regardless of the appellate outcome.
Request
Please acknowledge receipt of this claim and the enclosed Form 843 (Tax Year: _______ / Amount: $___________). Taxpayer respectfully requests that this claim be held in suspense pending a final decision in Kwong v. United States before the Federal Circuit. Please contact the taxpayer at the address above if additional information is needed.
Respectfully submitted,

This is a protective refund claim filed pursuant to Kwong v. United States, 179 Fed. Cl. 382 (Nov. 25, 2025), to preserve the taxpayer's right to a refund or abatement of [penalty/interest – specify] for the tax period ending [December 31, 20XX].
The U.S. Court of Federal Claims held in Kwong that the pre-November 2021 version of IRC § 7508A(d) created a mandatory postponement period running from January 20, 2020 through July 10, 2023 (May 11, 2023 + 60 days) and extended the two-year refund suit deadline under § 6532(a) accordingly. Consistent with that holding, [failure-to-file penalties / failure-to-pay penalties / underpayment interest – select applicable] assessed obligations within the January 20, 2020 – July 10, 2023 window may have been erroneously assessed and are subject to refund or abatement.
Taxpayer paid [describe: e.g., "failure-to-pay penalty of $XXX on Form 1040 for tax year 20XX"] on or about [date of payment]. IRC § 7508A(d) mandated an automatic, mandatory suspension of federal tax filing and payment deadlines for the full duration of the COVID-19 federally declared disaster period – January 20, 2020 through July 10, 2023 (May 11, 2023 plus 60 days).
The government filed a notice of appeal to the US Court of Appeals for the Federal Circuit on May 15, 2026; final resolution is pending. This claim is filed to preserve taxpayer's refund rights under IRC § 6511 pending resolution of that appeal.
Taxpayer requests refund or abatement of amounts that may have been erroneously assessed and collected, in an amount to be determined upon IRS review of taxpayer's account for the period at issue.
Legal basis: IRC § 7508A(d) (2019 version); IRC § 7508A(f) (P.L. 119-64, Dec. 26, 2025); Kwong v. United States, 179 Fed. Cl. 382 (Nov. 25, 2025)
Under penalties of perjury, I declare that I have examined this claim, including accompanying schedules and statements, and, to the best of my knowledge and belief, it is true, correct, and complete.
