What happens to my EIN if I change my business entity?

I'm changing my business from an LLC to a corporation, and I'm not sure if I can keep my current EIN or if I need a new one.

ARTICLE SUMMARY

Answer

It depends. Changing your business entity does not automatically mean you need a new Employer Identification Number (EIN). IRS rules specify when a new EIN is required and whether you can keep your existing EIN or need a new one depends on the type of entity change, or how the business is restructured.

Because an EIN is tied to your business for federal tax purposes, certain entity changes may require a new EIN, while others may only require updates to your business information.

When might you need a new EIN?

The answer depends on the type of business entity and the nature of the change. Factors that may affect your EIN include:

Your current and new business entity types.
Whether a new legal entity is being created.
IRS requirements for the specific conversion.
Changes to ownership or tax classification.
How the business is restructured.
Whether federal tax accounts need to be updated.

Reviewing these factors can help determine whether a new EIN is required.

What else should you update after changing your business entity?

Changing your entity type often affects more than your federal tax identification. Consider reviewing:

State business registration filings.
Tax registrations and accounts.
Business licenses and permits.
Business bank accounts.
Insurance policies.
Customer, vendor, and financing agreements.

Keeping these records current can help ensure your business information remains accurate after the change.

What to do next…

Determine whether your entity change requires a new EIN under IRS rules.
Review your federal, state, and local filing requirements.
Update your business registrations, tax accounts, and financial records as needed.
Notify banks, insurers, customers, and other affected parties if your business information changes.

What to consider in your specific situation

Your current and new business entity types.
Whether you're creating a new legal entity.
IRS rules for your type of entity conversion.
State filing and registration requirements.
Tax reporting and payroll obligations.
Existing contracts, licenses, and financial accounts that may need updating.
