Vehicle Sales Tax

When purchasing or leasing a vehicle in Indiana, sales tax is applied based on state law. Understanding how this tax is calculated helps you accurately estimate your total cost and avoid confusion during the buying process.

Indiana charges a 7% state sales tax on vehicle transactions. This tax is collected at the dealership for purchases and partially through lease payments for leased vehicles.

How Indiana Sales Tax is Calculated (Vehicle Purchases)

Sales tax in Indiana is calculated based on the net taxable amount, not simply the full purchase price.

Taxable Amount Includes:

  • Vehicle selling price
  • Document fee ($240)
  • Accessories added to the vehicle
  • Simoniz Glasscoat and similar protection products

Taxable Amount Excludes:

  • Trade-in value (deducted before tax is applied)

Example Purchase Calculation

  • Vehicle Price: $25,000
  • Trade-In Value: $10,000
  • Document Fee: $240
  • Simoniz Glasscoat: $1,195

Taxable Total:

$25,000 − $10,000 + $240 + $1,195 = $16,435

Sales Tax (7%):

$16,435 × 7% = $1,150.45

Trade-In Tax Benefit

Indiana provides a significant tax advantage when trading in a vehicle.

Because the trade-in value is deducted before tax is calculated, you only pay tax on the difference. This can reduce your total tax obligation compared to selling your vehicle separately.

Indiana Sales Tax on Leased Vehicles

Sales tax is handled differently on lease transactions.

What is taxed upfront:

  • Capitalized cost reduction
    • Cash down payment
    • Rebates applied to the deal

What is taxed over time:

  • The remaining tax is built into your monthly lease payments

These payments are made to the leasing company (lender), not the dealership.

County Taxes and Additional Fees

Some states and counties charge additional vehicle-related taxes.

  • Indiana does not collect county taxes at the dealership
  • Any applicable county or local fees are paid directly to the Indiana Bureau of Motor Vehicles at the time of registration
  • The Indiana Title Fee and Tire Fee are not taxed. Visit our page listing Dealership Fees for more information.

When Sales Tax is Paid

  • Purchase: Sales tax is collected at the dealership during the transaction
  • Lease: Partial tax is collected upfront, with the remainder included in monthly payments

This ensures compliance with Indiana law while simplifying the process for the customer.

Out-of-State Purchases

If you are purchasing a vehicle but registering it in another state:

  • Indiana's Sales Tax structure still applies
  • However, you will pay your home state's tax rate instead of Indiana's

Keep in mind that the transaction will legally occur in Indiana, therefore Indiana's tax laws will ultimately apply. Contact your finance manager for details specific to your situation.
