Vehicle Tax Rules We Model
Our car calculators — like Lease vs. Buy a Car — estimate two taxes that differ sharply between buying and leasing: sales tax (how a state taxes a lease, which a leaser pays again every few years) and any annual excise or property tax (a value-based tax that stays high for a leaser who is always in a newer car). This page shows the rules those tools use. Selecting your state in a calculator prefills these values, and every one remains editable.
Modeled rules by state

What the columns mean
- Lease sales-tax method
- States tax leases in structurally different ways. Taxing each monthly payment spreads the cost; taxing the full price (or the total of the payments) up front means a leaser who replaces the car every few years pays that tax again with each new lease.
- Trade-in credit
- Whether the state reduces the taxable price by a trade-in’s value. (Our simplified Buy vs. Lease tool does not model a trade-in yet, but other tools may.)
- Annual excise / property tax
- Some states or localities levy a yearly tax on a vehicle’s value. Because it falls as a car ages, a buyer’s bill declines over time while a leaser’s resets to a high, newer-car value every few years.
