What is Form 8822-B?
Form 8822-B, Change of Address or Responsible Party — Business, does two jobs. The first is routine: updating the mailing address or physical location tied to your EIN, so payroll notices, penalty letters, and correspondence reach you.
The second is the one with teeth: reporting a change in your responsible party — the individual who ultimately owns or controls the entity, named when the EIN was issued on Form SS-4. The IRS requires that change to be reported within 60 days. Ownership sales, leadership changes, and cleaning up an EIN opened by a formation service or former partner all trigger it.
Who files Form 8822-B?
- Businesses that moved — office, storefront, or the home office behind the LLC.
- Companies that changed hands — new ownership almost always means a new responsible party.
- LLCs formed by a service that listed the wrong person as responsible party.
- Nonprofits, estates, and trusts with EINs — the form covers every entity type.
Deadlines
Responsible-party changes: within 60 days of the change. Address changes have no statutory deadline, but notices sent to the old address remain legally effective — file promptly. Processing runs 4 to 6 weeks.
