March is graduation month and the Bureau of Internal Revenue (BIR) is reminding all schools to pay the corresponding P 15 documentary stamp tax (DST) for each diploma and official transcript of records given to their students. Furthermore, all documentation issued by these schools including certifications, transcripts and other records, are subject to the DST pursuant to Section 188 of the Tax Code.In line with its tax information campaign under “Making the Public Know” initiative, BIR Commissioner Joel Tan-Torres is appealing to all primary, secondary and tertiary schools to comply with this tax obligation.
