How much tax will you pay with a RUT-50?

Private party vehicle use tax is different from regular use tax or sales tax rates. 
In Illinois, your private party vehicle use tax rate depends on the cost of the car, and in some cases, its age. When filing a RUT-50, you have to determine the purchase price or the fair market value.
According to the Illinois Department of Revenue, the selling price is used as a default, but if there’s no sales price (such as if the vehicle was given as a gift), its market value will be used.
As of 2021, these were the tax rates for different vehicle values:
  • Between $15,000 and $19,999.99: Tax of $750
  • Between $20,000 and $24,999.99: Tax of $1,000
  • Between $25,000 and $29,999.99: Tax of $1,250
  • $30,000 or more: Tax of $1,500
If the market value was less than $15,000: The tax due is based on the age of the car, ranging from $390 for a new car to $25 for a car 11 years or older.
For motorcycles and all-terrain vehicles (ATVs): A flat rate of $25 applies.
For purchases or gifts to eligible family members or beneficiaries: A flat rate of $15 applies.
Key Takeaway: The amount of tax you pay on a car depends on its market value, as well as the amount you paid for it.
