|---|---|---|
| Basic lease or rental | The customer returns the motor vehicle to the lessor at the end of the lease or rental term. | Collect sales tax on each lease or rental payment. |
| Lease or rent with option to buy | The customer has the option of buying the motor vehicle during the lease or rental term or at the end of the term at fair market value. | Collect sales tax on each lease or rental payment and on the price the customer pays when buying the motor vehicle. |

| Basic lease or rental | The customer returns the motor vehicle to the lessor at the end of the lease or rental term. | Collect sales tax on each lease or rental payment. |
| Lease or rent with option to buy | The customer has the option of buying the motor vehicle during the lease or rental term or at the end of the term at fair market value. | Collect sales tax on each lease or rental payment and on the price the customer pays when buying the motor vehicle. |

At the end of the term, title to the motor vehicle passes to the customer for $0 or an amount that’s less than fair market value. | The customer will own the motor vehicle at the end of the lease or rental term, so this is a sale and a financing arrangement. Collect sales tax on the sales price of the vehicle at the beginning of the term, when the sale is made (the contract is completed). |
