Update Your Taxpayer Identification Number

To ensure accurate tax reporting for you or your business, and to prevent any possible IRS withholding, it is very important that you update your Square account to match IRS records. You can review or update the taxpayer identification information you provided to Square at any time directly from your Square Dashboard.

Follow the steps below to update this information:

  1. Log in with the email and password associated with your Square account.
  2. Enter your legal name and TIN exactly as it appears on file with the IRS in the first two boxes of the Taxpayer Information section.
  3. Click Save

If you receive an error when updating your information, try the following to resolve the issue:

  • Enter your legal name instead of your business name. Please note that a “Doing Business As” or “DBA” is not a filing recognized by the IRS. Be sure to enter your full legal name, e.g., John D. Smith DBA “John Smith Enterprises” should be entered as “John D. Smith.”
  • If you recently married, try using your maiden name. 
  • If you have a sole proprietorship, try entering your legal name. Sole proprietorships are generally under the owner’s name vs. the business name.
  • Verify that you are entering information issued by a federal agency such as the IRS or SSA (Social Security Administration) and not a state agency.
