What products and services are taxable in Massachusetts?

Physical products

There are a few exceptions, but almost all physical products are taxable when sold at retail in Massachusetts. Common examples include:

  • General merchandise like furniture, appliances, and clothing
  • Titled or registered items like vehicles

Food for consumption (with the exception of food sold at a restaurant is tax-exempt) in addition to certain clothing, prescriptions, medical equipment and manufacturing equipment is tax-exempt.

Labor in most cases isn’t taxable in Massachusetts. For instance, let’s say you broke the screen to your cell phone and take it to a cell phone repair shop to have it fixed. Sales tax would be added to the selling price of the new screen and any additional parts to fix the phone. The labor to replace the screen isn’t taxable. However, a business that makes furniture will indirectly have sales tax on labor. In this instance, let’s say this business is building a dining room table for a customer. Through labor, the pieces of wood are shaped, sanded and painted to build this piece of furniture. While the labor isn’t directly taxable, sales tax is charged to the final selling price of the table.

Sales tax reporting

When are Massachusetts sales tax returns due?

The Department of Revenue will determine a filing frequency based on the expected volume of sales, which will be monthly, quarterly or annually. Generally, a business collecting over $1,200 in sales and use tax each month will file monthly.

The due date for filings are the 20th day of the month following the reporting period, unless the 20th falls on a weekend or federal holiday, in which case would move to the next business day.

Even if the business had no sales during the reporting period, a filing is still required indicating no sales occurred.

Sales tax on purchases for resale

A business is able to purchase items to resell without paying state sales tax. The tax liability is passed from the wholesaler or distributor to the retailer who will then charge sales tax to the end-user of the item.

Wholesalers and distributors will require a sales tax number, and a completed Massachusetts Resale Certificate – Form ST-4) (also referred to as a sales tax exemption certificate) to document the items being purchased are for resale.
