The Philippines' tax system is anchored on voluntary compliance under the pay as you file as it is the taxpayer who is responsible for its tax compliance determining which tax should be paid, how to comply with various reports, and when to pay the same. It has a check and balance mechanism where the BIR has the right to conduct tax assessments or examinations within three years from filing the said returns, to determine the extent of compliance of taxpayers.
Under this, the BIR is clothed with such power to require taxpayers to submit to its authority for the purpose of determining such tax compliance and do such acts for collection of taxes due from taxpayers. Thus it is important for accountants to know the Philippines' tax system and the manner by which BIR conducts its audits. Furthermore, accountants must learn how the Courts decide on the assessments made by the BIR.
