Massachusetts Sales Tax Guide & Nexus Calculator (2026)
Massachusetts has a 6.25% state rate and partially taxes digital goods — prewritten (off-the-shelf) software is taxable whether delivered on disk or downloaded, while SaaS has been the subject of ongoing guidance updates. For digital sellers, Massachusetts requires careful product classification. Massachusetts is not an SST member.

Economic Nexus
Section titled “Economic Nexus”For informational purposes only · Not legal or tax advice · Consult a licensed tax professional · Rules as of 2026
Massachusetts’s economic nexus threshold is $100,000 in gross sales into Massachusetts in the current or prior calendar year. Once exceeded, registration and collection are required.
Massachusetts eliminated its 200-transaction alternative threshold before 2025. Marketplace-facilitated sales count toward the threshold.
Tax Rate and Product Taxability
Section titled “Tax Rate and Product Taxability”Massachusetts’s state rate is 6.25%. Massachusetts does not impose local sales taxes. The 6.25% rate applies uniformly across the state.
Higher rates in Massachusetts:
- Meals (restaurant food, prepared food): 6.25% (same as the standard rate; applied under a separate meals tax framework)
- Lodging: 5.7% state (local additions may apply via a separate occupancy tax)
- Marijuana retail: 10.75% state excise plus 6.25% sales tax
Standard retail e-commerce transactions are taxed at 6.25%.
Product Categories
Section titled “Product Categories”Taxable: Tangible personal property, prewritten computer software, most retail goods.
Exempt: Prescription drugs, groceries (food for home consumption), clothing items priced under $175 per item, qualifying agricultural and manufacturing inputs.
Clothing exemption: Massachusetts provides a per-item clothing exemption: individual clothing items costing less than $175 are exempt. Only the amount above $175 per item is taxable (not the full amount — just the excess). This per-item threshold, not the order total, determines taxability.
Digital Goods and SaaS
Section titled “Digital Goods and SaaS”Massachusetts takes a partial taxability approach to digital goods:
Taxable:
- Prewritten (canned) software — taxable whether delivered on a physical medium or downloaded electronically. Massachusetts has long taxed prewritten software and extended this to electronic delivery.
- Downloaded software — taxable as a sale of prewritten software delivered electronically
- Custom software modifications sold as prewritten — taxable if the modifications are sold separately
Not taxable or unclear:
- SaaS — Massachusetts has issued evolving guidance on SaaS. The DOR has at times treated SaaS as taxable (as electronic delivery of software) and at other times as a non-taxable service. Current guidance (as of 2024–2025) has moved toward treating some SaaS as potentially taxable, particularly where software is “delivered” to the customer for their use. Sellers should verify current DOR Letter Rulings or obtain guidance from a Massachusetts tax professional.
- Streaming services (audio/video) — not clearly taxable under current sales tax; Massachusetts has not broadly extended sales tax to streaming content
- Digital content (ebooks, digital music without a software component) — generally not subject to sales tax
The key Massachusetts distinction is between prewritten software (taxable) and pure services (not taxable). The DOR’s determination of whether SaaS is a sale of software or a service has been inconsistent and may depend on the specific product delivery model.
For SaaS sellers, Massachusetts is a state where you need specific guidance for your product. If your product involves the remote delivery of what is functionally a prewritten software application, Massachusetts may tax it.

| Less than $100/month | Annual |
| $100–$1,200/month | Quarterly |

Returns are filed through MassTaxConnect. Electronic filing is required for registered sellers.
Compliance Notes
Section titled “Compliance Notes”SaaS — get specific guidance: Massachusetts’s SaaS position is less settled than states with a clear taxable or non-taxable rule. If you sell SaaS into Massachusetts, obtain a DOR Letter Ruling or work with a Massachusetts tax professional to confirm the current treatment for your specific product.
Clothing exemption: The per-item $175 threshold is item-specific, not order-specific. A $160 jacket is exempt; a $200 jacket has $25 in taxable amount. Configure this correctly in your tax engine.
No local rates: Massachusetts’s single statewide rate simplifies collection despite the complexity of digital goods classification.
Not SST: Massachusetts is not an SST member. Multi-state SST registration does not cover Massachusetts.
Amazon FBA: Amazon operates in Massachusetts. FBA inventory creates physical nexus from dollar one.
Prewritten software sellers: If you sell boxed or downloaded prewritten software, you have a clear Massachusetts taxable obligation once you cross $100,000.
