What to save
- A signed copy of Form 8822-B exactly as mailed.
- Certified, registered, trackable, or private-delivery proof.
- Any later IRS correspondence that shows the address or responsible-party record changed.
Responsible-party timing
The IRS Form 8822-B page says responsible-party changes must be reported within 60 days. That is why the preview asks users to review responsible-party facts and route out if authority or control is disputed.
What Tax Paperwork cannot do
Tax Paperwork does not submit Form 8822-B, mail it, monitor IRS processing, or verify that IRS records changed. If the business needs proof for a deadline, bank, payroll provider, or government agency, keep independent proof and consider professional review.
