A nondividend distribution is a distribution that is not paid out of the earnings and profits of a corporation or a mutual fund. Typically it is a return of the capital or the investment that was made by the owner of the corporation or mutual fund.
Nondividend distributions are typically reported to the taxpayer-shareholder on Form 1099-DIV and they are typically not taxable, however once the taxpayer's basis in the corporation has been reduced to zero any subsequent nondividend distribution is considered a capital gain and is reported on Form 8949 flowing to Schedule D. It's up to the taxpayer to keep track of their basis in the corporation, reducing it by any nondividend distributions.
