A blended tax rate also known as the effective tax rate is arrived at any number of factors. The effective tax rate for individuals is the average rate at which their earned income, such as wages, and unearned income, such as stock dividends, are taxed. If you received income from a variety of things like stocks and bonds, interest, dividends or self-employment, this may all play a role in determining your blended tax rate. It is hard to tell though without knowing what type of income you received during the year. Original post by @DaveF1006
