Business tax deductible expenses are those costs a business incurs in order to generate revenue that can be used to reduce its taxable income. Common examples of such expenses include employee wages, advertising expenses, office rent, and materials used in the production of goods and services. By deducting these costs from taxable income, businesses are able to lower their overall tax burden and save money. To maximize savings, it is important for businesses to stay up-to-date with changing regulations and ensure all deductions are allowed under federal and state tax laws.
