01

Enter the subtotal

Use the price before sales tax.

See the original amount, tax, and final price.

A combined rate may have several parts

A purchase can be subject to national, state, provincial, county, or city taxes. Enter their applicable combined percentage rather than one component alone.

An estimate is not a tax determination

Product exemptions, shipping, discounts, and location rules can affect the taxable base. Use the rate and subtotal shown by the seller for a final transaction.

Sales Tax Calculator FAQ

What amount should I enter?

Enter the taxable subtotal before sales tax is added.

Can the rate contain decimals?

Yes. Rates such as 7.25% or 8.875% are supported.

Does this calculator find my local rate?

No. Tax rates and rules change, so you must provide the rate that applies.

Is shipping included?

Only if you include taxable shipping in the pre-tax amount. Local treatment of shipping varies.

How is the tax amount calculated?

The pre-tax amount is multiplied by the entered rate divided by 100.

Can I use it for VAT?

It can add any percentage to a net price, but it does not extract tax from a tax-inclusive total.
