How to calculate Sales Tax in New Hampshire?

As discussed earlier, almost all of the items are tax-free in NH, except the few so if you deal with the specific items mentioned above that are subjected to sales tax, than you can follow the steps below to calculate New Hampshire Sales tax.

It is easy to calculate the sales tax amount charged on the product and gross price (amount after tax) of a product.

Example # 1:

For instance, you sell a Pizza on your restaurant in East Concord, New Hampshire, having a net cost of $10. The amount of Sales Tax that you have to pay on the Pizza would be:

Manual Method:

Net Price (amount before Tax) of a Pizza: $10

Total Sales Tax rate: 0.00% (East Concord) + 0.00% (Merrimack County) + 9.00% (New Hampshire State) = 9.00%

Total Sales Tax amount = $10 x 9.00% = $0.9

Gross Price (Amount after Tax) = 10 + 0.9 = $10.9

The sales tax amount charged on the Laptop Charger would be $0.9, raising its gross cost to $10.9.

Using our Sales Tax Calculator:

All of the steps mentioned above can be skipped to get an instant result using our Sales Tax Calculator. All you need is:

  1. Input the $10 Net Price of a Pizza as Amount Before Tax
  2. Input or select 00% of the combined Sales Tax rate on the Tax Rate menu.

Reverse Sales Tax Calculation

In the example above, we have explained to you to calculate the Sales Tax amount payable in a product, and the Gross Price of the Product.

But there are times when you are required to deduce how much Sales tax you have actually paid on a product in New Hampshire.

This is where the Reverse Sales Tax Calculation Kicks in. And luckily, our New Hampshire Sales Tax Calculator can perform this calculation like a Pro.


The gross cost (amount after tax) of a Grilled Burger is $7, which you sell on your store in Derry, New Hampshire. If you want to deduce the amount of sales tax you have actually paid on it and the net cost (amount before tax) of a Grilled Burger, you can follow the following steps:

Gross Price (Amount after Tax) of Grilled Burger: $7

Total Sales Tax rate: 0.00% (Derry) + 0.00% (Rockingham County) + 9.00% (New Hampshire State) = 9.00%

Manual Method:

Gross Price with sales tax = [Net Price × (tax rate in decimal form + 1)]

7 = [Net Price x ((9/100) + 1)]

7 = Net Price x 1.09

$6.4 = Net Price


So the original Price (net price) of the Grilled Burger would be $6.4.

Using our Sales Tax Calculator:

You can also use our Sales Tax Calculator for Reverse Sales Tax calculation to skip the aforementioned manual method. All you need is:

  1. Input the $7 Gross Price of Grilled Burger as Amount after Tax
