Sales Tax Exemptions

Your organization may be eligible for any of the following exemptions to the state sales tax.  Please consult an accounting professional to determine whether your organization qualifies.

Small Business Energy Exemption


Instead of filling out Form ST-13 for each utility company, the business will complete the information for the exemption online through the Department of Revenue’s MassTaxConnect application to receive a Small Business Energy Exemption Certificate. The Certificate will be effective for two years, rather than one year as it had been.


All current exemptions have been automatically extended beyond December 31, 2018 to March 31, 2019. No action is necessary by the small business to extend the exemption.  The new process will be available on MassTaxConnect ( beginning January 1, 2019.

Information will be available on the Department of Revenue website under Business Taxes ( and will be updated, as needed, with any changes
