Explanation:
For small business owners, two of the most important determinations they can make are to calculate their marginal tax rates, along with their average tax rates. The marginal tax rate of a business is the percentage at which the last dollar entered was taxed.

The average tax rate is the percentage of your total taxable income that you pay in taxes.
