Use only felt-tip pens on disk labels. Make a backup of the magnetic media for your files in case the package sent to Social Security is lost or damaged. Copy the blank Form 6559 in TIB-4 and fill in a copy for each magnetic media file.
Instructions are on the back of the form.
Make sure these agree with the magnetic media Code A and B records. Fill in a separate Form 6559 for every tape and cartridge. Make sure the substitute shows the tax year and transmitter information at the top of each page. Substitute Form 6559 generated directly from your report program is acceptable to SSA as long as all the information shown on the actual form is displayed and the form includes the affidavit and signature used on the actual form.
