Massachusetts Sales Tax: Rates, Rules & Filing Guide

‍

Massachusetts sales tax is a flat 6.25% statewide. There is no county or city sales tax layered on top, which makes Massachusetts simpler to manage than most states.

SaaS is taxable in Massachusetts. So is prewritten software, no matter how you deliver it. Whether your customer downloads it, streams it from your servers, or gets it on a disc, the state treats it as tangible personal property and taxes it at 6.25%.

This guide walks through what's taxable, when you need to register, how to calculate the tax, and how to file and pay Massachusetts sales tax. 

Massachusetts Sales Tax at a Glance

Massachusetts sales tax is 6.25% on taxable sales, and that rate doesn't change based on where in the state you're selling. There's no general local sales tax, so a sale in Boston is taxed the same as a sale in Worcester or Springfield.

That said, a few local excises exist outside the general sales tax. Cities and towns can add a 0.75% local meals excise on restaurant food, which brings the tax on a restaurant meal to 7% in places that have adopted it. Cities that allow recreational marijuana sales can also add a local option tax of up to 3% on those sales. Neither of these applies to SaaS, software, or general merchandise.

Everything runs through MassTaxConnect, the Department of Revenue's online portal. You'll use it to register, file returns, and pay what you owe.

Taxable Categories: What Massachusetts Sales Tax Applies To

Tangible Personal Property (TPP)

Physical goods sold at retail are taxable in Massachusetts at the 6.25% state tax rate. Most items are taxable, but there are a few exemptions.

For example, groceries (unprepared food) are sales tax exempt, while prepared/restaurant food is taxable. 

Clothing is also partially tax exempt in the state. Any single clothing or footwear item priced at $175 or less is fully exempt. If an item costs more than $175, only the amount above $175 gets taxed. So if you sell a $200 jacket, you'd only charge sales tax on the $25 that exceeds the threshold, not the full item price.

Prescription drugs are exempt too, along with certain medical devices.

SaaS and Digital Products

SaaS is taxable in Massachusetts. Prewritten (also called "canned" or "off-the-shelf") software is taxable regardless of delivery method. It doesn't matter if your customer downloads it, accesses it remotely through the cloud, or gets it on physical media. If it's standardized software and not custom-built for one buyer, it's taxable.

The state does make an exception for custom software. If you build software to a specific customer's exact specifications, that's treated as a nontaxable professional service rather than a sale of tangible personal property.

Digital goods are taxable in the state. This includes downloaded movies, music, and e-books. The state classifies these as taxable tangible personal property.

Taxable Services

Most services are exempt from Massachusetts sales tax. Massachusetts, like a lot of states, taxes goods by default and only taxes services when the law specifically calls them out.

Telecommunications services are one of the exceptions. Phone, cellular, and similar telecom services are taxable. Internet access itself is exempt, thanks to federal law that bars states from taxing internet access services.

If you bundle a taxable product with a service, like software with mandatory support or maintenance, the whole bundle is generally taxable as part of the sale price.

Monitoring: When Massachusetts Sales Tax Applies to You

Economic Nexus Threshold

If your businesses grosses $100,000 or more from Massachusetts buyers in the previous or current calendar year then you have economic nexus in the state and are required to register for a sales tax permit and begin collecting.

This $100,000 amount includes both taxable and exempt sales. Though note that sales made through a marketplace facilitator that collects tax on your behalf generally don't count toward your own threshold, since the facilitator is handling that obligation separately.

Physical Nexus

Any physical presence in Massachusetts creates sales tax nexus. If you have an office, store, employee, contractor, inventory, or even if you do business temporarily there, such as at a trade show, you’re required to register and collect Massachusetts sales tax from your first sale. 

Marketplace Facilitators

Platforms that qualify as marketplace facilitators are required to collect and remit tax on behalf of the sellers using their platform. If you sell exclusively through a marketplace facilitator that's handling this for you, you typically don't need to separately collect tax on those sales. But if you also sell through your own website or store, you'll still need to register and collect tax on those direct sales once you cross the economic nexus threshold or if you have physical nexus in the state.

Calculation: Massachusetts Sales Tax Rates

State Rate

Since Massachusetts has a single flat 6.25% statewide sales tax rate, collecting sales tax in fairly straightforward. If a retail transaction is taxable, you generally just collect that rate from your buyer.

Though note that some localities add an optional meals excise tax of 0.75% or a 3% tax on marijuana. If you sell either of those products, you may be subject to additional tax beyond the state rate.

What the Rate Applies To

The 6.25% rate applies to taxable TPP, prewritten software, digital goods, and taxable telecom services. Massachusetts uses destination-based sourcing for out-of-state sellers, meaning the tax is based on where your customer is located, not where you're shipping from. Since Massachusetts has a single statewide rate, this generally only applies if you’re selling products that can be taxed differently, such as prepared food or marijuana. 

Shipping charges are typically taxable in Massachusetts, too, though the rules can change depending on how the charge is stated on the invoice.

Filing: How and When to File Massachusetts Sales Tax Returns

Filing via MassTaxConnect

All Massachusetts sales tax returns are filed electronically through MassTaxConnect. If you're registered but had no taxable sales during a period, you still need to file a zero return. Skipping a filing period, even with nothing to report, can trigger a penalty.

You can also file using paper Form ST-9, though most businesses elect to file directly through the portal.

Filing Deadlines

Massachusetts sales tax returns are due 30 days after the close of the reporting period. For monthly and quarterly filers, that typically lands near the end of the following month. Annual filers' returns are due 30 days after the close of the calendar year, generally by the end of January.

If your cumulative sales and use tax liability exceeded $150,000 in the prior calendar year, you're also subject to an advance payment requirement. You'll need to remit tax collected during the first 21 days of the month by the 25th of that same month, ahead of your regular return. Failing to meet that requirement results in fines and penalties.

Filing Frequency Thresholds

Your filing frequency depends on how much sales and use tax your business collects in a year.

‍

Businesses that exceed $150,000 in cumulative sales and use tax liability in the prior calendar year are also required to make advance payments on top of their regular monthly filing.

Late Filing Penalties

Massachusetts charges separate penalties for filing late and paying late. A late payment penalty of 1% of the unpaid tax applies per month, capping at 25% of the balance due. A separate late filing penalty of 1% per month also applies if you miss the filing deadline, also capping at 25%.

On top of penalties, interest accrues on unpaid tax at the federal short-term rate plus 4 percentage points, compounded daily, and that rate adjusts quarterly. Cases involving willful tax evasion or fraud can carry much steeper consequences, including criminal penalties.
