Does an EIN Expire? Inactivity, Updates and Business Closure

An EIN does not have an annual renewal date. Once assigned, it is the entity’s permanent federal taxpayer identification number. The IRS says it cannot cancel an EIN, although it can deactivate it when no longer needed. An unused number, a missing letter and an entity that has closed require different next steps. IRS: If you no longer need your EIN.

For an overseas LLC owner, check what happened to the business and its IRS account before submitting another SS-4.

If the LLC has been inactive

Time without revenue or business activity does not by itself create an EIN renewal requirement. Keep the assigned number and original records. Review whether the company still exists and whether it has outstanding filing obligations.

Do not infer that an inactive foreign-owned LLC has nothing to report. The Form 5472 instructions include certain formation-related amounts, contributions and distributions among the transactions relevant to a foreign-owned US disregarded entity. Lack of customer sales alone does not settle that filing question. Gather the actual transactions and obtain a review of the applicable obligations.

If you lost the EIN or its letter

Search the original IRS notice, past business tax returns, bank records and licensing records. If the number exists but you need documentary proof, use the IRS’s current verification options. A lost letter does not make the number expire.

The available paths include an Entity transcript, Letter 147C and digital CP575 for eligible Business Tax Account users. Eligibility and authority still need to be established. See EIN confirmation documents, and check an existing application if a formation provider may hold the records.

If the business details changed

An address or business-name change alone generally does not require a new EIN. Changes in ownership or structure can require one, depending on the entity and change. The IRS’s new-EIN guidance gives different rules by entity type.

For example, moving the same LLC’s mailing address should lead you to the update procedure. Adding a member or restructuring the business requires a separate analysis; do not assume the address-change rule covers it.

Use Form 8822-B for applicable business address, location or responsible-party changes. The IRS requires reporting a responsible-party change within 60 days. Keep a copy of the update with the EIN records.

If you are closing the company

EIN deactivation and legal company closure involve different processes. The current IRS deactivation guidance asks for a letter containing the EIN, legal name, address, assignment notice if available, and reason for deactivation. Use the mailing destination on that official page when preparing the request.

The IRS also requires outstanding returns and taxes to be resolved before deactivation in the circumstances it describes. Review its closing-a-business checklist, alongside the applicable state closure requirements. Sending a deactivation letter does not establish that every closure obligation has been completed.

Common questions

Must I pay a yearly IRS EIN renewal fee?

There is no annual EIN renewal. A provider’s charge for another service should identify what that service actually does. The IRS issues EINs for free.

Can I give the old EIN to a new company?

An EIN identifies its assigned entity. Review the new entity’s requirements rather than treating an old number as a transferable asset.

Is this the same as ITIN expiration?

No. ITINs are individual identifiers with separate renewal rules. See EIN vs ITIN and the IRS’s ITIN renewal guidance.

Can EINPilot renew or deactivate my EIN?

Those tasks are outside the planned first-time EIN preparation and fax-assistance service. EINPilot is currently a product preview; real applications, payments and submissions are not available.
