If you receive a dividend income report without a payer's identification number, enter the information as though you had received a Form 1099-DIV Dividends and Distributions, but leave off the Payer's Federal Identification Number (FEIN). This number is not required and the return will e-file without the number. The information required by the IRS is transferred to Schedule B (Form 1040) Interest and Ordinary Dividends and/or Schedule D (Form 1040) Capital Gains and Losses of the return as necessary.
