There are two types of tax benefits associated with leasing.
For an expensive vehicle, the state sales tax can be substantial. With a lease, in most states, sales tax can be incorporated into the monthly payment schedule. This provides the car owner with the use of that money over the term of the lease.
Many of our clients use their cars for business purposes, and lease their cars in a business name; which need not be a legal corporate entity. A Ferrari, Lamborghini or Rolls Royce, for example, can certainly impress prospects and customers. Leasing in a business name allows you to use pre-tax dollars to make monthly payments.
Always consult with your accountant or financial advisor regarding this type of tax-related decision.
