A registered medical patient in Massachusetts pays no state cannabis tax on a medical purchase. A shopper buying adult-use pays the 10.75% state excise and the 6.25% state sales tax, which adds up to 17%, plus a local tax of up to 3% in towns that charge it. Below are the official rates, a calculator and a table of examples.

| Tax | Adult-use purchase | Medical purchase |
|---|---|---|
| State excise tax | 10.75% | None |
| State sales tax | 6.25% | None |
| Local tax (a town can choose it) | Up to 3% | Exempt |
| All together | 17% to 20% | 0% |
The Commission puts it in three sentences:
"There is no state excise tax on medical marijuana sales." "There is no standard sales tax on medical marijuana sales." "However, medical marijuana sales are exempt from the local tax option."
Type what you spend in a month, before tax. Pick the local tax if your town charges one. You will see the estimated tax on an adult-use purchase, the tax on a medical purchase, and the difference.
The calculator needs JavaScript. Without it, use the table below: it shows the same estimates for five monthly amounts.
| Monthly spend before tax | Adult-use tax, no local tax | Adult-use tax, 3% local tax | Medical tax |
|---|---|---|---|
| $50.00 | $8.50 | $10.00 | $0.00 |
| $100.00 | $17.00 | $20.00 | $0.00 |
| $200.00 | $34.00 | $40.00 | $0.00 |
| $300.00 | $51.00 | $60.00 | $0.00 |
| $500.00 | $85.00 | $100.00 | $0.00 |
