We changed the business name but not its legal entity. Do we need a new EIN?
A business name change alone generally does not require a new EIN when the same legal entity continues.

A business name change alone generally does not require a new EIN when the same legal entity continues. The IRS notification method depends on entity type and filing circumstances. State registrations, payroll accounts and bank records need coordination, but a branding change is not itself a new taxpayer.
A specific business-owner situation
A corporation adopts a new legal name and payroll proposes creating a new EIN account. That could fragment deposits and filings if the corporation itself has not changed.
Illustrative example, not a client result.
What to establish before filing
- Confirm whether the legal entity continues.
- Follow the IRS entity-specific name-change procedure.
- Coordinate payroll and other account updates.
Which fact changes the answer?
A name-only amendment differs from a new entity or qualifying ownership and structure change. The legal transaction determines whether a new EIN is needed.
A mistake to avoid
Do not obtain a replacement EIN solely to solve a name mismatch without checking the actual requirement.
Records that support the decision
- State name-change documents.
- EIN confirmation.
- IRS notification and payroll records.
The decision to document
Keep the existing account when appropriate and retain confirmation that the IRS recognizes the revised name.
