  "description": "Registering a car costs $60 in one state and $1,400 in the next, and the reason is what each state chooses to tax. Some charge a flat plate fee, some scale by vehicle weight, and a large group levies an annual ad valorem or personal property tax on the car's value that keeps billing you every year. Layer sales or use tax on the purchase price — which several states calculate after a trade-in credit and several do not — and the out-the-door number stops resembling the sticker. This calculator prices the one-time cost of getting on the road and the recurring annual cost separately, with a trade-in credit toggle because it is worth hundreds. Worked assumption for the defaults: a $28,000 purchase with a $6,000 trade-in in a 7.25% state that credits the trade, $75 title, $120 plates and registration, and a 1% annual value-based tax — about $1,790 up front and roughly $400 in year two.",
  "formula": "Up front = (price − trade-in credit) × sales tax + title + plates + registration + doc fee; annual = value-based tax + renewal + weight fee.",

      "q": "Does the trade-in really change the tax?",
      "a": "In most states, yes, and it is the largest single lever here: trading a $6,000 car in a 7.25% state saves about $435 versus selling it privately and buying without a credit. A handful of states, including California, tax the full price regardless."

    {
      "q": "Do I pay sales tax again if I move states?",
      "a": "Usually you owe use tax in the new state with credit for tax already paid, so you pay the difference if the new state's rate is higher. Moving within a few months of purchase is when this bites — check the new state's DMV rules before the deadline."

    {
      "q": "Are these fees the same for a private-party purchase?",
      "a": "The taxes generally are; the dealer doc fee disappears and some states use a value guide rather than your bill of sale if the declared price looks low."
