State lease-tax notes

Illinois lease taxes and dealer fees

The tax on a lease depends on more than the monthly payment. Start with the Illinois rules below, then check how the dealer has applied them to your quote.

How Illinois taxes a lease

Tax up front on total lease payments — Typical for Illinois; check your contract.

A simple payment-times-rate estimate may miss part of the tax here. Check the state notes and ask for the dealer's tax worksheet.

Ask how the dealer worked out the taxable lease amount and which local rules apply. Check the written calculation before comparing totals.

State portion: 6.25%. Local tax and the charges being taxed may change the total.

We haven't confirmed a combined rate for your location. Ask which state and local rates the dealer used.

Tax is an estimate. The calculator may not cover every rule that applies to your lease. Ask the dealer for the tax calculation behind your quote.

Check the dealer's paperwork fee

A documentation fee is charged by the dealer. Keep it separate from government title and registration charges, and ask what it covers.

A limit of $377.63 may apply in some cases; ask the dealer what the fee covers.

Before you sign

  • Which location and tax rule did you use for this lease?
  • What amount is being taxed, and which fees and credits are included?
  • Which taxes do I pay at signing, and which are added to the lease?
  • What does the documentation fee cover, and which rule applies to it?
  • Can you put the full calculation and itemized fees on the worksheet?
