The IRS does not consider an operating lease to be a purchase, but rather a tax-deductible overhead expense. Therefore, you can deduct the lease payments from your business income. Also, because lease payments are treated as expenses on a company's income statement, equipment does not have to be depreciated over five to seven years.
With leasing, you are able to customize a program to address your needs & requirements - cash flow, budget, transaction structure, cyclical fluctuations, etc. For example, some leases allow you to miss one or more payments without a penalty, an important feature for seasonal businesses.
