A.“Commencement of Business” – in the case of pursuit of business or practice of profession, it shall be reckoned from the day when the first sale transaction occurred or within thirty (30) calendar days from the issuance of Mayor’s Permit/Professional Tax Receipt (PTR) by LGU, or Certificate of Registration issued by the Securities and Exchange Commission (SEC), whichever comes earlier.

B.“Primary Registration” – the process by which a person, whether an individual, including estates and trusts, or a corporation and other juridical entities, upon application and full compliance with the registration requirements prescribed in these Regulations, is registered with and consequently included in the registration database of the Bureau of Internal Revenue (BIR).

ii. PURELY TIN ISSUANCE – refers to issuance of TIN to applicants under Executive Order (EO) 98, series of 1998 e.g. in the case of individuals required to incorporate the TIN in all forms, permits, licenses, clearances, official papers and documents which they secure from other government agencies e.g. Local Government Unit (LGU), Department of Trade and Industry (DTI), Land Transportation Office (LTO), Department of Foreign Affairs (DFA), etc. It also includes issuance of TIN to Overseas Filipino Workers (OFWs)/Overseas Contract Workers (OCWs) as defined under these Regulations as well as to Non-Resident Foreign Corporations (NRFC)/Non-Resident Alien not engaged in Trade or Business (NRANETB) subject to final withholding tax on income derived from sources within the Philippines.
