Tax added at three rates, and the pre-tax price when 7.25% is already included:
| Amount | Tax at 6% | Tax at 7.25% | Tax at 9% | Pre-tax if 7.25% is included |
|---|---|---|---|---|
| $25 | $1.50 | $1.81 | $2.25 | $23.31 |
| $100 | $6.00 | $7.25 | $9.00 | $93.24 |
| $250 | $15.00 | $18.12 | $22.50 | $233.10 |
| $500 | $30.00 | $36.25 | $45.00 | $466.20 |
| $1,200 | $72.00 | $87.00 | $108.00 | $1,118.88 |
On a $1,200 laptop the difference between a 6% and a 9% combined rate is $36. If a total already includes 7.25% tax, divide by 1.0725 – do not just subtract 7.25%.
Divide the total by 1 plus the rate as a decimal. $268.13 ÷ 1.0725 = $250.00 before 7.25% tax.
Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax, though some Alaska towns charge a local one.
It depends on the state and whether shipping is listed separately. Check your state revenue department.
Combined state and local rates above 9% are found in several states. The Tax Foundation publishes an annual table.
Usually no when you buy the card; tax is charged when the card is used to buy taxable goods.
US taxpayers who itemize can choose to deduct state and local sales tax instead of income tax, within the SALT limit.
