Common confusion points

Form 2120 vs. Form 8822 – both change addresses; 2120 is for returns/responsible parties, 8822 is for individuals only.

When to use 2120 for a partnership – often 8822‑B is required; verify entity type.

Electronic filing availability – not all taxpayers have e‑file access; default to mail.

Signature requirement – a faxed signature is not accepted; must be original.

Address format – IRS rejects if ZIP+4 is missing or street abbreviation is incorrect.
