Step 1: Gather records
Start with the notice, the account transcript, the filed return copy, and proof of payment if relevant.
Kwong explainer
Kwong IRS deadline: why July 10, 2026 matters.
The Kwong IRS deadline issue is not about an automatic refund. It is about whether certain penalties and interest tied to deadlines in the COVID postponement window may be worth preserving before July 10, 2026.
Core window
January 20, 2020 through July 10, 2023 is the main period being reviewed.
Main practical date
TAS says most taxpayers will generally need to act by July 10, 2026.
Main posture
The issue is still being litigated, so preserving rights matters more than overclaiming certainty.
Bottom line
The Kwong IRS deadline question comes from a Taxpayer Advocate Service explanation of the Kwong decision and its implications. TAS says the COVID federal disaster declaration ran from January 20, 2020 through May 11, 2023, and the additional 60 days extended the tax postponement period to July 10, 2023.
Under that reasoning, filing and payment deadlines falling in that window may not have been late until after July 10, 2023. That is why taxpayers are reviewing penalties and interest assessed during that period and why July 10, 2026 is so important for many claims.
What Kwong changed in practical terms
TAS explains that under the court’s reasoning, some taxpayers may be entitled to refunds or abatements of certain amounts assessed during the COVID period, including late-filing penalties, late-payment penalties, estimated tax penalties, and interest that may have started too early.
You may have something worth reviewing if
- You had a filing or payment deadline that fell between January 20, 2020 and July 10, 2023
- The IRS assessed penalties or interest tied to that deadline
- You already paid the charge, still owe it, or it became part of a payment plan
- The issue relates to an individual return, business return, payroll filing, estate, trust, or other federal tax matter
Technical note: The original due date tied to the return, payment, or filing obligation matters more than the year printed on the notice by itself.
Why July 10, 2026 matters
TAS says most taxpayers will need to file claims by July 10, 2026. That is the practical deadline many DIY and CPA-assisted taxpayers are working against now.
The reason is straightforward: relief is generally not automatic. In most cases, the IRS does not issue a refund or abate an assessed amount unless a taxpayer files a claim.
What that means for you
- Do not assume the IRS will fix the issue automatically
- Do not wait for a final appellate outcome before gathering your facts
- Use the current period to identify the tax year, charge type, and original due date
What a protective claim is
TAS says taxpayers should consider protective claims because the law is still uncertain. A protective claim is mainly about preserving your right to a refund while the issue continues through litigation or later guidance.
TAS also explains that a protective claim does not need a final dollar amount, but it does need to identify the issue clearly and point to the specific year or years involved.
What to do next
Step 2: Confirm dates
Write down the tax period, the original due date, and the dates tied to assessment or payment activity.
Step 3: Decide the path
Self-check further, hand it to your CPA, or use optional specialist help if the facts are messy.
Step 4: Preserve, don’t overclaim
Focus on preserving a possible claim before the deadline rather than acting as if the legal issue is already final.
