Rhode Island car sales tax: 7% and what it applies to

• Rhode Island charges 7%, and that rate is the same everywhere in the state — no county or city adds to it on a vehicle purchase.

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

• Who collects the tax: in Rhode Island you pay the 7% sales tax and the DMV's fees at the DMV, not to the dealer. The dealer completes the state's sale form, and can take your payment and register the car for you. Some dealers charge for that service, usually $100 to $300 according to the Attorney General, and have to refund any amount above the DMV's actual fees. The calculator includes the tax and fees because you pay them either way.
• The rate is 7% statewide. Rhode Island has no city, county or district sales tax on vehicles.
• A trade-in lowers the taxable amount only when it is a private passenger car and the car you buy is one too. Trucks, including pickups, get no trade-in credit, as a trade-in or as the purchase. If you are buying or trading in a pickup, tick the truck boxes under More options and the calculator drops the credit.
• A manufacturer's rebate and a dealer discount both lower the taxable amount. That is friendlier than the many states that tax the price before a rebate.
• The dealer's doc fee (a "documentary preparation fee") is capped at $400 and may be charged only on a sale over $10,000. A separate title preparation fee is capped at $20. Both are taxed. The Attorney General says both are negotiable and a dealer does not have to charge either. These limits apply to dealers located in Rhode Island.
• Accessories the dealer installs are taxed. A service contract or extended warranty is not taxed when it is optional and listed on its own line.
• The registration figure is an estimate. It assumes a car in the 4,001 to 5,000 lb bracket and a two-year registration. The DMV prorates a new registration by date, so it can be lower. Heavier SUVs and trucks pay more: $48 a year from 5,001 to 6,000 lbs, and up.
• Buying from a dealer in another state: you still pay Rhode Island's 7% at the DMV, with credit for any sales tax you paid that state. Rhode Island's limits on dealer fees do not apply to a dealer located elsewhere.
