Frequently asked questions
What is the sales tax rate in New Hampshire?
New Hampshire has no statewide sales tax (0%). Any sales tax you see would come from local rules, not the state.
How much is sales tax on $100 in New Hampshire?
At the state level it is $0 in New Hampshire, since there is no statewide sales tax. Local taxes, where they apply, would add to that.
Is sales tax origin-based or destination-based?
Most states are destination-based, so the rate is the one where the buyer receives the item — your address for an online order or the store for an in-person purchase. A few states are origin-based for in-state sellers, charging the rate at the seller's location. For ordinary shopping the destination rate is what you see; sourcing mainly affects online sellers deciding which rate to collect.
Can I deduct sales tax on my federal tax return?
If you itemize, you can deduct either your state income tax or your state and local sales tax, but not both, as part of the capped SALT deduction. Sales tax is usually the better choice in no-income-tax states or in a year with large taxable purchases. The IRS publishes an official Sales Tax Deduction Calculator for an exact figure.
How do I calculate sales tax?
Multiply the pre-tax price by the sales tax rate as a decimal, then add it to the price. For example, a $100 item at a 7% rate is $100 × 0.07 = $7 in tax, for a $107 total. Enter your amount and rate above and it’s worked out instantly.
How do I reverse sales tax from a total?
To find the pre-tax price from a tax-included total, divide the total by 1 plus the rate. A $107 total at 7% is $107 ÷ 1.07 = $100 pre-tax, so $7 was tax. Switch the calculator to “Reverse” mode to do this automatically.
What is the sales tax rate in my state?
Statewide base rates range from 0% (in five states) to over 7%, and most places add local county and city taxes on top. Pick your state on the by-state pages to load its base rate, then adjust for your local rate if you know it.
Which states have no sales tax?
Five states have no statewide sales tax: Delaware, Montana, New Hampshire and Oregon, plus Alaska (which has no state tax but allows local sales taxes). In those states, choosing the state sets the rate to 0%.
