There is no state sales tax in Delaware—but before you cross state lines to save money on buying a car, note that the car must be registered in Delaware to skip the sales tax. 
  • Delaware does not charge sales tax on car purchases, but it requires a documentation fee of 4.25% based on a vehicle’s NADA book value.
  • Buyers must register their new vehicle in Delaware to avoid paying sales tax.

Delaware car sales tax rate

Delaware is one of a few states that has no state sales tax. Other states with no car sales tax include:
  • Alaska
  • Iowa
  • Maryland
  • Montana
  • New Hampshire
  • New Mexico
  • North Carolina
  • Oregon
  • South Dakota
Of the three counties in Delaware, the only one that has a local sales tax is Sussex County, at a rate of 6%. 
Delaware does charge a documentation fee of 4.25 % on all motor vehicle sales. This is based on the purchase price or the
NADA book value
—whichever is greater. 

Delaware car trade-in taxes 

If you have a trade-in, the value of it is deducted from the purchase price of the new car when it comes to determining your documentation fee. 
For example:
  • You’re buying a new
    BMW 230i
    in Wilmington for $37,000 and trading in your old
    Dodge Charger SE
    for $7,000
  • You will only pay the 4.25% documentation fee on $30,000 of your new car’s value 
Keep in mind: If the dealership is offering any incentives or rebates, those generally aren’t deducted from the price of the car when it comes to determining your document fee.
