Sales Tax Exemption

Authorized purchases for ACAT are exempt from Massachusetts Sales Tax. Vendors may require one or all of the following:

  1. Our Exemption Number: 270-287-252 (which the observant viewer will notice is the same as our Federal EIN: 27-0287252).
  2. A copy of our ST-2 Certificate of Exemption.
  3. A copy of our renewed ST-2 Certificate of Exemption.

Our certificate expires 18 January 2030.
