A 1099 form is a tax document used in the United States to report various types of income that are not related to employment, such as interest, dividends, or capital gains from investments. There are several variations of the 1099 form, each designed to report specific types of income. These forms are issued by Apex and sent both to clients and the Internal Revenue Service (IRS). Clients must review these forms carefully to ensure the reported amounts’ accuracy and that they are properly included in their tax filings.
