Pennsylvania car sales tax: rate, sourcing and what it applies to

• Pennsylvania's rate is not a single statewide number — it is resolved from the ZIP code you register in, because local jurisdictions add to the state rate. Across Pennsylvania the combined rate runs 6% to 8%, so where you register genuinely changes what you owe.
• The rate that matters is the one where you register the vehicle, not where the dealership sits. Buying out of your area does not change what you owe.

• Taxed on top of the vehicle price: dealer-installed accessories and extended warranties and service contracts.
• Not part of the taxable amount: the dealer doc fee.
• Your trade-in comes off before tax is calculated.

• Pennsylvania sales tax is based on the county you REGISTER the vehicle in (destination-based) — 6% statewide, plus 1% for Allegheny County and 2% for Philadelphia, even if you buy from a dealer elsewhere in the state.
• Your trade-in reduces the taxable amount, with no dollar cap.
• Manufacturer rebates AND dealer cash discounts both reduce the taxable amount in Pennsylvania — unlike some states that tax the rebate.
• The dealer's documentary fee is NOT subject to sales tax in Pennsylvania, and is capped: $490 max if filed electronically, $409 max if filed on paper (CPI-adjusted yearly).
• Extended warranties and other F&I products ARE taxable in Pennsylvania.
• Some counties add an optional $5/yr 'Fee for Local Use' at registration — not included here since it doesn't apply statewide; check with your county if you're unsure.
