How to Change a Name on a TIN

How to Change a Name on a TIN
Notify the IRS if your business name changes.

Notify the Internal Revenue Service of your business name change; the process is the same for all Sole Proprietorships, Corporations and Partnerships so long as a tax return has already been filed for the year.

Compose a letter to the IRS stating your business's former name, the new name and your employer identification number as well as the date of the name change. Name change letters for Sole Proprietorships must be signed by the business owner or authorized business representative, a corporate officer of a Corporation or a partner of a Partnership.

Mail your letter to the IRS address where you file your business income tax return.
