Explanation

Customers who subscribe to Avalara Managed Returns or Certified Service Provider services must identify all companies by their US Taxpayer ID Numbers (TIN). In general, a taxpayer ID number is either an Employer Identification Number (EIN) assigned by the Internal Revenue Service or a Social Security Number (SSN) assigned by the Social Security Administration.

EIN numbers are in the format 12-3456789, whereas most SSN numbers are in the format 123-45-6789. The number is used to correctly report taxes on your returns and to correctly match your corporate entities with your tax returns.
