Yes, and you can amend or deactivate your EIN for a number of other reasons, too. IRS Changes EIN Requirement to Increase Security Effective May 13, 2019, the IRS requires individuals applying for an EIN to use a Social Security Number or ITIN for the responsible party on the form. How to Change Your Employer ID Number If You Made a Mistake If you made a mistake on your EIN application, such as if you listed a non-owner or officer in Item 3 or elsewhere, do not submit a new EIN application, Form SS-4. Instead, submit a letter to the IRS, preferably on your company letterhead. Include the name and the taxpayer identification number of the current principal officer, general partner, grantor, owner, or trustor. Be sure to include the entity's complete name, EIN, and your mailing address so the IRS can correctly identify your IRS account. If you Made Changes to Your Business If you change your business name after you receive your EIN, write to the IRS at the address where you file your tax return. An authorized person from your company must sign the letter. If you change the name of your partnership or corporation, you must include a copy of the Articles of Amendment that you filed with your state to authorize the name change. Note Changing your business name may require you to notify the IRS, in addition to changing your EIN. See this IRS article on Business Name Change for more details. If you change your address or you change the responsible party for your business you must use Form 8822-B, Change of Address or Responsible Party – Business to notify the IRS of your new address. You must report this change within 60 days. When You Need a New Employer ID You may not be able to just make a change on your EIN in some circumstances. Whether your business needs a new EIN depends on your business type.

Partnerships must get a new EIN if: They incorporate (form a corporation)The partnership is taken over by a partner and becomes a sole proprietorshipThe partners end the partnership and begin a new one. Note Limited liability companies (LLCs) are not recognized by the IRS as tax entities. They must follow the EIN change regulations for the business type of their taxing status – sole proprietorship, partnership, or corporation (including S corporations). How to Cancel an Employer ID Number When an employer ID number is given to a business, that EIN is not reused for any other business ever. It stays with and continues to belong to the business that applied for it and for which it was used for tax purposes. This means you can't really "cancel" an EIN. But if you decide that you don't need the number anymore, you can cancel your account with the IRS. You can close your business account with the IRS by writing to "Internal Revenue Service, Cincinnati, Ohio 45999." State the reason why you want to close the account and include the complete legal name of your business, the EIN, and the business address. If you have a copy of the confirmation letter you received from the IRS when you set up your EIN, include it. You must pay any taxes for which you are liable before you close the account. This includes income taxes according to your business type, payroll taxes, and other employment taxes.
