Cancelling Your EIN and Notifying the IRS When You Close a Business

You cannot actually cancel an EIN. The IRS treats the number as permanently assigned to your business and never reissues it to anyone else, so when you close down you are not deleting a number, you are closing the business account tied to it, a step the IRS's own checklist labels "cancel your EIN and close your IRS business account."

What an EIN actually is

An EIN, or Employer Identification Number, is the permanent federal taxpayer identification number for that business, the entity's equivalent of a Social Security number. It appears on your federal returns, your payroll filings, your 1099s, and the paperwork behind your business bank accounts. Because the number is tied to the business permanently, it stays on file with the IRS even after the company stops operating, and it is not handed to a different business later.

That permanence is the reason "cancelling" it is the wrong mental model. There is no form that erases an EIN. What you can do is tell the IRS the business is done and ask it to close the account associated with the number.

File the final returns before you close the account

The IRS will not close the account while anything is outstanding. Its page states plainly that "We cannot close your business account until you have filed all necessary returns and paid all taxes owed." On the same checklist, filing a final return is step one and closing the account is step five, so the order is built in: the returns come first.

Filing a final income tax return means using the form for your entity type and checking the box that marks the return as final wherever the form provides one. Which return applies, and whether you also owe final employment tax returns or other forms, depends on how the business is organized and is a question for your CPA. Our guide to the final return and the records behind it walks through what each entity files and why that final filing matters more than it looks. Skipping it does not just delay the account closure; a required return that is never filed leaves that year open to examination with no defined end date.

The letter you send

Once the returns are handled, closing the IRS business account is done by mail. The IRS asks for a letter that includes the complete legal name of the business, the business EIN, the business address, and the reason you want to close the account. The closing-a-business page lists those exact contents, tells you where to send the letter, and asks you to include a copy of the EIN assignment notice if you still have the one issued when the number was first assigned. Follow the address and instructions on that page directly rather than reusing a mailing address from an old article, since the IRS updates where correspondence goes.

There is no fee, and the letter itself is short. It is a federal step only: closing your IRS business account does not close any state tax accounts, sales-tax permits, or registrations the business held, which each follow your state's own process. Keep a copy of what you send with your permanent records, so you have proof of when and why you asked the account to be closed.

Closing the account does not end your record-keeping

Closing the business account with the IRS ends the ongoing account, but it does not erase past filing years or your obligation to keep the records behind the years the business operated. The IRS retention windows still apply, generally three years for a standard return, four years for employment tax records, six years if a return understated gross income by more than 25 percent, and seven years for a worthless-securities or bad-debt claim, with no limit if a return was fraudulent or never filed. If your business was an LLC, our guide to the records to keep when dissolving an LLC covers which documents to hold and for how long after the entity is gone.

So the letter that closes your IRS account is close to the last step, but the paperwork it points back to has to survive for years. That includes the accounting file, which often holds the records needed to support prior returns. If your books are in QuickBooks Online, cancelling the subscription is not a neutral cleanup step: a cancelled paid company stays read-only for 12 months and is then permanently deleted, and a cancelled trial gets only 90 days, which is far shorter than the IRS windows above. The safe move is to build a complete, verified copy of the books before you cancel. If you would rather hand that off, it is the archive we build for you: the full ledger, every report in cash and accrual basis, and every attachment still linked to its transaction, checked against your live books before the subscription ends.
