District of Columbia Car Sales Tax Calculator

Calculate the exact excise tax on your next vehicle purchase in District of Columbia.

Applies the District of Columbia weight-based motor-vehicle excise tax, which scales with the vehicle's gross weight class rather than a flat sales tax, to estimate the tax owed when you title and register a car at the DC DMV.

Does the District of Columbia charge a car sales tax?

The District of Columbia does not charge a conventional percentage sales tax on vehicles. Instead it levies an excise tax at titling whose rate is set by the vehicle's gross weight class, so heavier vehicles are taxed at a higher percentage of their value.

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.
