How Connecticut sales tax works
Every taxable purchase in Connecticut starts with the 6.35% state rate. Because Connecticut doesn't permit local sales taxes, that's also your final rate anywhere in the state, which makes totals easy to predict.
To figure the tax yourself: multiply the price by 0.0635. A $250.00 purchase generates $15.88 in tax for a total of $265.88. To back the tax out of a receipt total, divide by 1.0635 instead. The calculator above does both.
