Dividend income from stocks and mutual funds are reported on taxes. Generally, one can use either Form 1040 or Form 1040A to report the dividend income. Ordinary dividends are reported on Form 1040 Line 9a[i]. Some dividends qualify for reduced tax rates and these are called Qualified Dividends. These dividends are reported on Form 1040 Line 9b[ii].
Individual taxpayers generally use either Form 1040 or Form 1040A to report dividend income. However, Form 1040 must be used if the taxpayer is reporting qualified dividend income or receives a nontaxable distribution required to be reported as capital gains[iii].
