Pennsylvania Sales Tax Calculator

How it works

Sales tax is a percentage added to the price of taxable goods and services. Multiply the amount by the rate, then add it back for the total:

sales tax = amount × combined rate

total = amount + sales tax

The rate this calculator applies is each state's combined rate — the statewide sales tax plus the population-weighted average local rate — as published by the Tax Foundation for 2026. Most states let counties and cities add their own local sales tax on top of the state rate, so the combined figure reflects a typical purchase in that state.

Rates range widely: Louisiana is the highest combined rate at 10.11%, followed by Tennessee (9.61%) and Washington (9.51%). Four states — Delaware, Montana, New Hampshire and Oregon — levy no sales tax at all. Alaska has no statewide sales tax, but its local jurisdictions average 1.82%.

Hawaii and New Mexico technically have no retail sales tax — they tax a seller's gross receipts (a general excise or gross-receipts tax) — but the effect on your receipt is similar, so their combined rates appear here as the Tax Foundation reports them.

Because the state figure is an average, your exact address may differ — a specific city or district can be higher or lower. If you know your local rate, enter it in the custom rate field to override the state average.

Worked example

The same $100 purchase is taxed differently by state: $9.61 in Tennessee (9.61%), $8.99 in California (8.99%), $6.60 in New Jersey (6.6%), and $0 in Oregon, Delaware, Montana or New Hampshire, which have no sales tax. Select your state above for its exact rate and total.

Frequently asked questions

How do I calculate sales tax?

Multiply the pre-tax amount by the sales tax rate as a decimal, then add it to the amount: tax = amount × rate, total = amount + tax. For a $100 purchase at an 8.99% rate, the tax is 100 × 0.0899 = $8.99 and the total is $108.99.

Which states have no sales tax?

Four states levy no sales tax at all: Delaware, Montana, New Hampshire and Oregon. Alaska has no statewide sales tax either, but it allows local jurisdictions to charge their own, which average about 1.82%. Everywhere else combines a state rate with local rates.

What is a combined sales tax rate?

It is the state sales tax rate plus the average local (county and city) rate. Most states let localities add their own sales tax, so the combined rate — a population-weighted average of those locals on top of the state rate — better reflects what a shopper actually pays than the state rate alone.

Why is my local rate different from the one shown?

The rate here is a statewide average, so a specific city or special taxing district can be higher or lower — combined rates within a state can vary by several percentage points. If you know the exact rate for your location, enter it in the custom-rate field to override the average.

How do I find the total price including tax?

Add the sales tax to the pre-tax amount: total = amount + amount × rate, which is the same as amount × (1 + rate). A $100 item at 8.99% comes to 100 × 1.0899 = $108.99. This calculator shows both the tax and the total.

Are all goods and services taxed at this rate?

No — states carve out exemptions and special rates. Groceries, prescription drugs and some services are often exempt or taxed at a reduced rate, while a few states tax them fully. This calculator applies the general combined rate; check your state's rules for exempt categories.

Does this include the highest possible local rate?

No — it uses the state's average combined rate, not the maximum. Some localities levy more than the state average — a specific address can run several percentage points higher — so use the custom-rate field when you know the precise local rate.
