Most services are not taxable in Massachusetts. The state’s 6.25% sales tax applies to retail sales of tangible personal property and to a short list of specifically named services; a purely service-based transaction stays outside the tax unless a statute pulls it in. The complications start when a service also hands the customer something physical, or when software is involved.
The Default: Services Are Exempt
Chapter 64H of the General Laws imposes the 6.25% excise on retail sales of tangible personal property and on enumerated services performed in the Commonwealth.1General Court of Massachusetts. Massachusetts General Laws Part I, Title IX, Chapter 64H, Section 2 If your work never puts a physical product into the customer’s hands, it is presumed non-taxable. Legal advice, accounting, medical consultations, haircuts, personal training, and management consulting all sit on the exempt side.2Massachusetts Department of Revenue. Sales and Use Tax
The Department of Revenue’s Service Enterprises regulation, 830 CMR 64H.1.1, sets out a two-part test. A transaction escapes tax when the real object is the service itself, and either no tangible property changes hands or the property is an inconsequential element of the deal. “Inconsequential” generally means the property is worth less than 10% of the total charge, though the DOR treats that as a guideline rather than a bright line.3Massachusetts Department of Revenue. 830 CMR 64H.1.1: Service Enterprises
Which Services Are Taxable
A handful of service categories are taxed at the standard 6.25% rate.
Telecommunications
Telecommunications services are the biggest taxable category. The tax covers the transmission of messages or information by electronic means, including local and long-distance calls and mobile service. The definition specifically excludes cable television and internet access.4Massachusetts Department of Revenue. 830 CMR 64H.1.6: Telecommunications Services Your phone bill carries tax; your broadband subscription does not.
Gas, Electricity, and Steam
Sales of gas, electricity, and steam to a purchaser are taxable at 6.25%.2Massachusetts Department of Revenue. Sales and Use Tax Massachusetts treats these utility deliveries as sales of tangible personal property rather than services.
Meals and Prepared Food
Restaurant meals and other prepared food from vendors carry the 6.25% state tax. Many cities and towns have adopted a local-option meals excise of 0.75%, bringing the effective rate to 7% in those municipalities.5Massachusetts Department of Revenue. Sales Tax on Meals Restaurants, caterers, and food trucks all fall inside this rule regardless of the service work involved.
When Your Service Also Transfers Goods
This is where most businesses get caught. Once a service transaction includes some transfer of physical property, the tax treatment depends on how central the goods are and how the invoice is written.
The 10% Guideline
Under the Service Enterprises regulation, if the property transferred is worth less than 10% of the total charge and you do not separately state its price on the bill, the whole transaction is treated as a non-taxable service. You pay sales tax when you buy the supplies yourself, and that ends the matter.3Massachusetts Department of Revenue. 830 CMR 64H.1.1: Service Enterprises
If the property’s value exceeds 10%, or if you break it out as a separate line item, the property portion becomes taxable. If the property exceeds 10% and you did not separately state it, the DOR can tax the entire receipt.3Massachusetts Department of Revenue. 830 CMR 64H.1.1: Service Enterprises Itemize your invoices.
Fabrication
When a vendor takes raw materials and produces a finished product for a customer, that is a fabrication and it is taxable. A print shop that produces custom brochures from paper and ink is selling tangible personal property, not performing a service, even though labor is the largest input.2Massachusetts Department of Revenue. Sales and Use Tax
Repair Work
Labor on a repair is not taxable when parts and labor are separately stated on the invoice. Only the parts charge is taxed.6Massachusetts Department of Revenue. Letter Ruling 85-8: Auto Repairs If the repairer lumps everything into a single charge and parts run to 10% or more of the total, the entire amount can be taxed. Auto mechanics and appliance repair shops sit squarely in this rule.
Installation and Real Property
Installation labor is not taxed as long as the charge is separately stated from the property being installed. And labor performed under a contract for the construction, reconstruction, alteration, or repair of real property is not taxed at all.2Massachusetts Department of Revenue. Sales and Use Tax Replacing a furnace that becomes a permanent fixture, putting on a new roof, or renovating a bathroom are real property improvements, and the labor is exempt no matter how the invoice reads.
Software and Cloud Services
Software is the category where the rules diverge sharply from how other services are treated.
Prewritten Software
Standardized (prewritten) software is taxable at 6.25% regardless of the delivery method. Disc, download, or remote server access, it makes no difference. Taxable transfers include licenses, leases, upgrades, and rights to use software hosted on someone else’s server.7Massachusetts Department of Revenue. 830 CMR 64H.1.3: Computer Industry Services and Products
Custom Software
Custom software development is generally exempt. When the principal object of the transaction is the programmer’s or systems analyst’s professional service, and any physical media delivered is inconsequential, it counts as a non-taxable service. The same 10% guideline applies. But if custom programming is bundled as a mandatory part of a taxable sale of hardware or prewritten software, the entire charge becomes taxable.7Massachusetts Department of Revenue. 830 CMR 64H.1.3: Computer Industry Services and Products
SaaS and Cloud Computing
Cloud arrangements get a case-by-case analysis under the object-of-the-transaction test. Where the customer’s real purpose is to access computing resources and storage, and any use of prewritten software on the provider’s server is incidental, the DOR has ruled the transaction non-taxable.8Massachusetts Department of Revenue. Letter Ruling 12-8: Cloud Computing Pure infrastructure (remote storage, raw compute) generally comes out exempt. A standard SaaS product where the customer’s real object is using the software itself will often be taxable, because the DOR treats charges to access or use prewritten software on a remote server as taxable sales of that software.2Massachusetts Department of Revenue. Sales and Use Tax The line between using someone’s software and buying computing resources that happen to include software is genuinely fuzzy, and the DOR evaluates each arrangement on its own facts.
Other Digital Content
Digital content that is not software (downloaded music, video, books) is not taxed when delivered electronically.2Massachusetts Department of Revenue. Sales and Use Tax The same music on a CD or the same book in paperback is taxable. Delivery method controls the outcome.
Buying Taxable Services for Resale or Exempt Use
A business that buys a taxable service or product and resells it in the regular course of business can buy tax-free by giving the vendor a completed Form ST-4, the Massachusetts Sales Tax Resale Certificate. The vendor has to verify the certificate is properly filled out and signed, and keep it in permanent tax records. In an audit, the burden of proving a sale was not a taxable retail sale falls on the vendor unless a valid resale certificate is on file.9Massachusetts Department of Revenue. Form ST-4 Sales Tax Resale Certificate
Materials, tools, fuel, and machinery used directly in manufacturing, processing, or converting tangible personal property are generally exempt. Businesses claiming this exemption use Form ST-12, the Exempt Use Certificate, and the exemption extends to replacement parts and maintenance services for qualifying production equipment.9Massachusetts Department of Revenue. Form ST-4 Sales Tax Resale Certificate Section 501(c)(3) organizations can apply for a Certificate of Exemption (Form ST-2) through MassTaxConnect, and vendors should keep a copy on file just as they would a resale certificate.10Massachusetts Department of Revenue.

Registering and Filing
Any business selling taxable services or property in Massachusetts must register with the DOR through MassTaxConnect before collecting tax. Registration requires your EIN (or SSN for sole proprietors without employees), your business start date, and owner or officer contact information. The DOR mails a Form ST-1 registration certificate, which has to be posted and visible at your business location.11Massachusetts Department of Revenue. Register Your Business with MassTaxConnect
Out-of-state businesses with no physical presence in Massachusetts still have to register and collect if their remote sales to Massachusetts customers exceed $100,000 in a calendar year.2Massachusetts Department of Revenue. Sales and Use Tax This economic nexus rule covers taxable services and tangible personal property alike. A remote seller of taxable software subscriptions that crosses the threshold is a vendor with collection obligations.
Filing frequency depends on estimated annual liability. Businesses estimating $100 or less for the calendar year file once, with the return and payment due by January 20 of the following year. Businesses estimating more than $100 but not more than $1,200 file quarterly, each return due by the 20th of the month after the quarter ends. Businesses estimating more than $1,200 file monthly, each return due by the 20th of the following month. Meals tax has its own schedule.12Massachusetts Department of Revenue. 830 CMR 62C.16.2: Sales and Use Tax Returns and Payments
Use Tax When the Vendor Doesn’t Collect
When a vendor does not collect Massachusetts sales tax on a taxable transaction, the buyer owes use tax at the same 6.25% rate directly to the DOR.13Massachusetts Department of Revenue. Sales and Use Tax for Businesses This commonly comes up with out-of-state purchases and online transactions where no tax was charged. Businesses buying taxable software, telecommunications, or other taxable items from vendors who don’t collect Massachusetts tax need to self-report and pay use tax on their own returns.
What Happens If You Get It Wrong
The consequences of miscollection are more than the tax itself.
- Late filing penalty of 1% of the unpaid tax per month or fraction of a month, up to 25%.14Massachusetts Department of Revenue. Massachusetts Penalties and Interest Assessed by DOR
- Underpayment interest, compounded daily, at 8% for the first quarter of 2026; the rate adjusts quarterly based on the federal short-term rate plus four percentage points.15Massachusetts Department of Revenue. TIR 25-8: Interest Rate On Overpayments And Underpayments
- Personal liability. Sales tax is a trust-fund tax; the money you collect belongs to the Commonwealth until remittance. If a business fails to pay it over, any officer, employee, or member with a duty to remit is personally and individually liable for the amount owed.16General Court of Massachusetts. Massachusetts General Laws Chapter 64H, Section 16
The personal liability provision means an LLC or corporation will not shield an owner or officer if collected sales tax goes unremitted. Classifying transactions correctly at the start costs far less than defending an audit later.
