Ordinary dividends (box 1a). Distributions from a corporation or mutual fund start with a presumption: a dividend on common or preferred stock is an ordinary dividend unless the payer says otherwise. Ordinary dividends come out of earnings and profits and are ordinary income, shown in Form 1099-DIV box 1a.
Qualified dividends (line 3a). Some of those ordinary dividends also qualify for the lower capital-gain rate as qualified dividends, reported on line 3a against ordinary dividends on line 3b. The lower rate applies only if all three tests are met: the payer is a U.S. corporation or qualified foreign corporation, the dividend is not on the disqualified list, and the shareholder meets the holding period. For common stock that means holding more than 60 days during the 121-day period beginning 60 days before the ex-dividend date; for preferred stock with dividend periods totaling more than 366 days it means more than 90 days during the 181-day period beginning 90 days before the ex-dividend date. A box 1b figure alone does not make dividends qualified when the holding test fails.
Nondividend distributions (box 3). A nondividend distribution in box 3 is a return of capital rather than earnings: it reduces stock basis and is not taxed until basis is fully recovered, and only the excess after basis reaches zero is reported, on Form 8949 Part I (held 1 year or less) or Part II (held more than 1 year).
Exempt-interest dividends (box 12) and capital gain distributions (box 2a). Exempt-interest dividends from a mutual fund or regulated investment company, shown in box 12, pass through the fund’s tax-exempt interest to the shareholder for the calendar year. Capital gain distributions in box 2a are reported directly on Form 1040 line 7a or, when required, Schedule D line 13; a fund’s net realized short-term capital gains are not treated as capital gains but arrive as ordinary dividends.
Money market funds pay dividends, not interest. Money market funds are offered by non-bank financial institutions such as mutual funds and stock brokerage houses, and pay dividends: generally, amounts you receive from money market funds should be reported as dividends, not as interest. Report amounts you receive from money market funds as dividend income, and do not confuse them with bank money market accounts that pay interest.
Reinvested dividends, service charges, nominees, Schedule B. Reinvested dividends stay taxable: stock bought through a dividend reinvestment plan at fair market value is still dividend income, and any service charge subtracted before reinvestment is dividend income too. Dividends received as a nominee belong on Schedule B Part II with the nominee amount backed out, and ordinary dividends above $1,500 also require Schedule B Part II.
Worked example
Ana’s Form 1099-DIV shows $2,000 in box 1a, of which the fund identifies $1,500 as qualified, plus $300 in box 3 and $400 in box 12. Her basis in the shares is $4,000, which fully covers the box 3 distribution. Ana reports $2,000 as ordinary dividends with $1,500 of that as qualified, reduces her basis by the $300 box 3 return of capital to $3,700 with nothing reported for it this year, and treats the $400 box 12 amount as exempt-interest dividends for the year.
