Form 843 COVID protective-claim workflow is closed

PostalForm is not accepting new orders for the COVID-era Form 843 protective-claim workflow. The Taxpayer Advocate Service identified July 10, 2026 as the general protective-claim date for the specific relief discussed in the former guide. PostalForm will not represent that a new mailing after that date preserves the expired date.

What you can do now

  • Do not start or reuse the expired COVID protective-claim workflow.
  • Use the current IRS Form 843 instructions to determine whether a different, timely Form 843 use applies to your facts.
  • If a qualified tax professional prepares a different timely filing and gives you the correct destination, you can upload and mail the completed PDF. PostalForm does not determine eligibility, deadlines, or the IRS mailing address.
