How do I register for a sales tax permit in Massachusetts?
If you’re selling taxable goods or certain services in Massachusetts, you need a sales tax permit before making your first sale. The state calls it a Certificate of Registration, and you get it by registering with the Massachusetts Department of Revenue.
Registration happens online through MassTaxConnect at mass.gov/masstaxconnect. Create an account if you don’t have one, then register for a sales and use tax account. You can register for other tax types at the same time if needed, like meals tax for restaurants or room occupancy tax for short-term rentals.
You’ll need your business information including legal name, address, federal EIN (or Social Security Number if you’re a sole proprietor), business structure, and the date you expect to start making taxable sales. Massachusetts also asks about owners, officers, or partners with significant ownership stakes, so have those details ready.
Once approved, you receive your Certificate of Registration. This authorizes you to collect the 6.25% Massachusetts sales tax from customers on taxable transactions. You’re required to display the certificate at your business location. The DOR assigns a filing frequency based on your expected tax liability. Most new businesses start with quarterly filing, though higher-volume sellers file monthly.
Filing deadlines depend on your assigned frequency. Quarterly returns are due by the 20th of the month following each quarter. Monthly returns are due by the 20th of the following month. Miss a deadline and penalties start immediately. The state treats sales tax seriously because you’re holding customer money in trust until you remit it.
Not everything you sell is taxable in Massachusetts. Groceries, clothing under $175 per item, and prescription medications are exempt. Most professional services like consulting or legal work aren’t subject to sales tax. But services involving tangible property can be taxable, and the rules get specific. If you’re unsure about your products or services, check before you start selling.
Working with an Andover, MA bookkeeper who handles sales tax compliance can save time and prevent mistakes. Getting registered correctly from the start is easier than correcting errors after the state sends a notice. And once you’re registered, staying compliant with filing and remittance becomes another recurring task that needs to happen on schedule.
