How Illinois Taxes Leases
Unlike buying, where you pay sales tax on the full negotiated price of the vehicle, leasing taxes vary wildly by state.
- Upfront Full Price: Illinois taxes the full purchase price of the vehicle, even if you are only leasing it. This severely hurts the value of leasing in this state.
A worked example for Illinois
Take a $35,000 vehicle. Buying it in Illinois means paying its 8.82% sales tax on the full price — roughly $3,087 in tax alone, due up front or rolled into your loan (where you also pay interest on it).
- Leasing is taxed on the full $35,000 price anyway, so you carry nearly the same $3,087 tax burden without ever owning the car — a strong argument for buying in Illinois.
These are illustrative figures. Registration, title, and documentation fees are extra and vary by county — confirm them with your Illinois DMV or dealer.
