Excise Tax
An excise tax can be imposed by both state and local authorities on a variety of products, activities, services, occupations and privileges. Excise tax is often included in price of a product such as cigarettes or alcohol. 

Personal Property Tax
Personal property is composed of goods, merchandise, equipment, tools, machinery, furniture, furnishings and other movable items not attached to or part of the real estate (land, buildings and other attached improvements).  It is assessed separately from the real estate to certain businesses, public utilities, and owner of homes that are not their primary residences.

Local assessors are required to assess a personal property tax on all personal property not expressly exempt that is situated in their community under the provisions of M.G.L. Chapter 59.  There are many exemptions depending on ownership entity, property type or property use.
