Yes — interest paid on business loans is generally fully tax deductible as a business expense, reducing your effective cost of capital. If your business is in the 25% tax bracket, a loan at 10% APR effectively costs 7.5% after the tax deduction. This makes business loans much more economical than they appear on the surface.
