Business tax deductions are categories of expenses that a business may subtract from its income before calculating how much it will owe in taxes. These deductions can include the cost of goods and services that the company needs to run its operations, as well as employee salaries and benefits. The goal is to lower the amount owed so that the company pays less in taxes. With the right tax deductions, businesses can save money and invest more in their operations, allowing them to stay competitive and grow.
