A business tax deduction is an expense that a business can subtract from its taxable income when calculating its federal income tax liability. Deductions can reduce a business’ taxable income and lower the amount of taxes owed to the government each tax year.

Here’s how it works:

  1. Calculates your business’ gross income, which is the total amount of money it earned during the tax year.
  2. Next, subtract qualified business expenses, such as rent, salaries, supplies, and other business-related expenses, from its gross income. We’ll go through the 30 most common business expenses further down below.
  3. The result is the business’ taxable income, which is the amount on which it must pay federal income taxes.

What counts as a business expense?

To determine what expenses are tax deductible for businesses, you can check the IRS guidelines and regulations or ask your bookkeeper or accountant. Generally, to be counted as a write off, business expenses must be ordinary, necessary, and reasonable. Ordinary expenses are those that are common and accepted in your industry. Necessary expenses are those that are helpful and appropriate for your business. Reasonable expenses are those that are not excessive in amount.

Below is a list of the 30 biggest tax deductions for businesses.
