General Principles of Taxation
Taxation represents a vital connection between citizens and their government. As taxpayers provide revenue, the government uses these funds to deliver public services such as free education, infrastructure, and national defense.
The primary purpose of taxation is to raise revenue, but it serves secondary purposes too. Regulatory taxation helps control certain activities (like sin taxes on alcohol or tobacco), while compensatory taxation aims to reduce social inequality through progressive tax systems.
Several theories explain taxation's importance. The Necessity Theory states that since government existence is necessary, taxation must also be necessary. The Lifeblood Theory asserts that without taxes, the government cannot function. The Benefits-Protection Theory describes the reciprocal relationship where citizens pay taxes and receive government protection in return.
Important Note: Taxation is characterized by being a forced contribution, generally payable in money, levied for public purposes, exclusively imposed by the legislature, within the state's jurisdiction, and proportionate in character.
The three branches of government play distinct roles in taxation. The legislative branch has the inherent power to create tax laws, while the executive branch (through agencies like BIR and BOC) handles administrative functions like assessment and collection. The judiciary interprets tax laws and resolves disputes.
A sound tax system follows three principles: fiscal adequacy (revenue exceeds expenses), equality (based on ability to pay), and administrative feasibility (taxes are reasonable to implement and collect).
