How it works

The sales tax maths, with a worked example

$100 in California, at the 7.25% statewide rate plus a 1.25% local rate.

The rate

Rate = state rate + local rate.

  • California: 7.25%
  • Local: 1.25%
  • Combined: 8.5%

The tax

Tax = taxed subtotal × rate ÷ 100, rounded to the nearest cent.

  • $100.00 × 8.5 ÷ 100
  • Tax = $8.50
  • Half a cent rounds up

The total

Total = all items + tax.

  • $100.00 + $8.50
  • Total = $108.50
  • State part $7.25, local $1.25

5 states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire and Oregon. Alaska still has local sales taxes in many boroughs and cities. California (7.25%), Utah (6.1%) and Virginia (5.3%) are shown with the local part every address pays, because each state publishes that sum as its statewide rate. Hawaii charges a general excise tax on the business, Arizona a transaction privilege tax and New Mexico a gross receipts tax; sellers usually pass these on.

Add or remove

Adding tax vs taking it out

The same 8.5% rate, worked forward and backward. Remove tax lands back on the exact price.

Price before tax
$108.50total

Add tax

You know the shelf price. Tax = $100.00 × 8.5% = $8.50, so you pay $108.50.

Price × (1 + rate)

Total with tax
$100.00before tax

Remove tax

You have a total that includes tax. Before tax = $108.50 ÷ 1.085 = $100.00, and the tax is the rest: $8.50. Don't take 8.5% off the total: that gives $9.22, which is wrong.

Total ÷ (1 + rate)

Verdict: divide, don't subtract. The tool rounds the price before tax to the cent and gives the rest to tax, so the two always add back to the total you typed.

What's taxed

Not everything is taxed the same

Each state decides which items it taxes, and at what rate. A few examples from the states' own sites.

Groceries

Food is often lower or free

Many states tax groceries at a lower rate or not at all. Mark them No tax, or work them out as a separate sale at the lower rate.

  • Illinois: food and drugs at a lower rate
  • Mississippi: groceries at 5%
  • Tennessee: food at a 4% state rate
Clothing and medicine

Check your state's list

Clothing, prescription medicine and some services are exempt in some states and taxed in others. Your state's tax site has the list.

  • Rules differ state to state
  • Some depend on the price
  • Mark exempt items No tax
Pro tips

Pro tips for getting the tax right

Small checks that keep the estimate close to your receipt.

Use the address

The total rate depends on the exact address. Use your state's official lookup when the tool links one.

Copy a receipt's rate

A recent receipt from the same store shows the full rate. Type the part above the state rate as local.

Divide to remove

To find the price inside a total, divide by 1 + rate. Taking the rate off the total gives too much tax.

Mark exempt items

Groceries or medicine on the same receipt? Mark them No tax so they stay out of the tax.

Three decimals

Rates like 4.225% and 6.875% are exact here. Local rates take up to three decimals too.

Copy the breakdown

Paste the state and local parts, each item and the total into an invoice, email or note.

Compare states

Switch the state to compare statewide rates side by side. The amounts and items stay as you typed them.

Rates change

States change their rates from time to time. These were checked November 2026, and we re-check each January.

An estimate, not tax advice

The total rate depends on the address, and some items (groceries, clothing, medicine) are taxed differently by state. A store can also round item by item, so a receipt may differ by a cent. For filing or collecting tax, follow your state's tax department.

Use cases

Everyday sales tax sums it handles
