No. To be brutally honest, the fact that you are even asking this question suggests that you need to take some business courses or hire an accountant before you invest in any kind of business. You could really mess up your taxes and owe massive penalties.
When you buy a business, you are investing your personal money in the business. It's an investment, like buying gold or stocks or a house. If you later sell the business for more than you invested, that will be a taxable capital gain in the year you sell the business. That taxable gain would be in addition to any taxable income the business generates from regular month to month or year to year operations. If the business goes bankrupt or you sell it for less than your investment, you may have a deductible loss when that happens, but that gets complicated and you would need further tax advice at that time.
