What are you leasing? Is it going to be used as a business asset? If so:
$8,000 will translate to a monthly lease payment of $2xx for 36 months. The business can can itemize the monthly lease payment as an expense, reducing your tax liability on net profit. At the end of 3 yrs, you own the product if you choose the "one dollar buyout" option.
The other options are:
a. using cash-flow to buy the equipment. You now own the equipment but have $8,000 less in working capital to grow your business.
b. Borrow the money from the bank. You'll need a higher down payment to collateralize the loan. You can write off the interest but the depreciation will take twice as long to recapture from a tax standpoint.
Typically, leasing makes more sense for a small business owner. UMMV. Suggest to speak to an accountant to be sure.
