Plain-English distinction

  • Form 843 is used for certain refund or abatement requests involving taxes, interest, penalties, fees, or additions to tax.
  • Form 3911 is used to help trace a refund check that was issued but not received, lost, stolen, or destroyed.
  • Form 14039 is an identity-theft affidavit for tax-related identity theft situations.

Why this stays education-only

These are issue-resolution workflows. The risk is not only whether the boxes are filled correctly; it is whether the user picked the right path, included the right facts, and avoided sending sensitive identity information to the wrong place.

Tax Paperwork should not provide penalty strategy, refund dispute advice, identity-theft incident handling, or document intake before counsel and tax review.

Current status

Education-only. Do not send notices, refund checks, identity-theft facts, SSNs, ITINs, EINs, addresses, police reports, FTC reports, or signed forms to Tax Paperwork support.
