How to work out Boston sales tax by hand
Turn the rate into a decimal by dividing by 100: 6.25% becomes 0.0625. Multiply the price by it to get the tax, then add the tax to the price.
Example: a $84.99 item in Boston has $84.99 × 0.0625 = $5.31 in tax, so the total at the register is $90.30.
To find the price before tax from a receipt, divide the total by 1 plus the rate: $50.00 ÷ 1.0625 = $47.06 before tax, with $2.94 of tax included.
Stores round tax to the nearest cent. If a receipt is a cent off from this calculator, it's usually because the store rounds each item separately rather than the whole bill.
