The deadline for filing electronically with the Internal Revenue Service is typically (for most, but not all, form types and amounts) the last day of March. This can be a day or two later if that falls on a weekend. If 1099 Services is only filing with the IRS for your company (rather than also mailing recipient copies), your Information Return data must be provided to 1099 Services by March 25.
Upon completion of recipient copy mailing you will receive a report of all mailed recipients in PDF format. For very large transactions sets we may have to transmit in a Zip archive due to email attachment size constraints.
