The District of Columbia does not levy a flat percentage car sales tax. Instead it charges a weight-based excise tax when you title and register a vehicle: the rate rises in tiers as the vehicle’s gross weight increases. This tool estimates that excise tax from the price and weight class.
How it works
The taxable base is the vehicle’s fair market value (the purchase price for a dealer sale), and the rate is chosen from a tiered weight schedule:
rate % = tier rate for the selected weight class
excise tax = price × rate %
Lighter passenger cars sit in the lowest tier, mid-weight vehicles in a middle tier, and heavy SUVs and trucks in the top tier. DC also offers reduced rates for cleaner or more fuel-efficient vehicles, so the schedule used here is a representative approximation.
Example and notes
A 30,000 dollar vehicle in the mid-weight tier at a 7% rate would owe
30,000 × 0.07 = 2,100 dollars in excise tax. This figure is excise tax only —
the District of Columbia also charges weight-based registration fees and a title
fee at the counter. Always confirm the current excise schedule and any
fuel-efficiency adjustments with the DC DMV before you budget, since the tiers
and rates are updated periodically.
