My TIN number is giving an "invalid" error


  • I am an Asset Store Publisher
  • I am filling in my tax interview
  • I have entered myTIN number but it is coming up with a "TIN not valid" error


There are a number of reasons this might occur:

  • You are entering your U.S. TIN in the Foreign TIN field.
  • You are entering a U.S. TIN that is not registered in the U.S. IRS database for that name, resulting in a Name-TIN mismatch.
  • You are entering a U.S. TIN including hyphens. Do not include hyphens when entering
    your U.S. TIN.
  • You are entering an invalid U.S. TIN.
  • You are entering an invalidly formatted Foreign TIN. For example, you are entering a
    VAT number instead of a TIN.
  • You are copying and pasting your TIN instead of typing it out.


Please check the causes above and ensure you are not entering your TIN incorrectly or in the wrong part of the form. If in doubt, please contact your local tax authority for advice.
