Massachusetts charges a flat statewide sales tax of 6.25% as of 2025, with no county or city add-ons. This calculator lets shoppers, sellers and accountants add that 6.25% to a pre-tax price or strip it back out of a tax-inclusive total in one step.
How it works
Enter an amount and choose a mode:
- Add sales tax — your amount is the pre-tax price. Tax =
price × rate ÷ 100, and the total =price + tax. At 6.25%, total =price × 1.0625. - Remove sales tax — your amount is the tax-inclusive total. Pre-tax =
total ÷ (1 + rate ÷ 100), so at 6.25% pre-tax =total ÷ 1.0625, and the tax is the difference.
The rate defaults to 6.25%. Massachusetts has no local sales tax, so you normally leave it unchanged.
Example
A $200 purchase, Add sales tax at 6.25%: tax = 200 × 0.0625 = $12.50, total =
$212.50. Going the other way, entering $212.50 in Remove sales tax mode returns
a pre-tax price of 212.50 ÷ 1.0625 = $200.00 and $12.50 of tax.
| Pre-tax price | Tax at 6.25% | Total |
|---|---|---|
| $50.00 | $3.13 | $53.13 |
| $100.00 | $6.25 | $106.25 |
| $200.00 | $12.50 | $212.50 |
