This memorandum exhaustively examines the legal framework governing local taxation and tax exemptions in the Philippines. The power of local government units (LGUs) to generate their own revenue is a cornerstone of local autonomy under the 1987 Constitution and the Local Government Code of 1991 (LGC). However, this power is not absolute and operates within a complex system of constitutional limitations, statutory enumerations, and judicial interpretations. The central issues involve delineating the scope of local taxing powers, the nature and validity of tax exemptions, the interplay between national and local tax authority, and the remedies available to contest local tax measures.

The 1987 Constitution establishes the principle of local autonomy. Section 5, Article X mandates that each LGU shall have the power to create its own sources of revenue and to levy taxes, fees, and charges, subject to such guidelines and limitations as Congress may provide. This provision is the fountainhead of local fiscal power, but it explicitly subordinates it to congressional regulation. Furthermore, Section 28(3), Article VI provides that charitable institutions, churches, parsonages or convents, mosques, non-profit cemeteries, and all lands, buildings, and improvements actually, directly, and exclusively used for religious, charitable, or educational purposes shall be exempt from taxation. This constitutional exemption is self-executing and imposes a direct limitation on both national and local taxing powers.

The LGC is the primary statute implementing the constitutional grant of local fiscal autonomy. It provides the specific mechanisms and limitations for local taxation.

LGUs can exercise the power to tax only if expressly authorized by the LGC. The power is not inherent but statutory. The fundamental limitations are outlined in Section 133 of the LGC, which enumerates the entities and subjects that LGUs cannot tax. These include, inter alia: the National Government and its agencies; local water districts; cooperatives duly registered under relevant laws; and the transfer of national government assets. Furthermore, LGUs cannot impose taxes on items already subject to specific national internal revenue taxes, except as provided in Section 142 (on manufacturers, importers, or producers of certain products) and Section 151 (on banks and other financial institutions) of the LGC. The doctrine of preemption applies; where the national government has chosen to tax a particular field comprehensively, local taxation on the same field is generally prohibited.

Taxing powers of LGUs are construed strictly against the LGU and liberally in favor of the taxpayer. Any doubt or ambiguity in a local tax ordinance is resolved against the LGU and in favor of the taxpayer. This principle arises from the fact that the LGU’s power is delegated and limited by statute.

While limited, the grant of taxing power to LGUs is not merely ministerial. The Supreme Court has upheld the doctrine of local fiscal autonomy, recognizing that LGUs have a wide degree of discretion in creating their own sources of revenue and in setting rates, provided they operate within the confines of the LGC. The test for validity is whether the tax ordinance is within the statutory authority granted and complies with the prescribed procedures.

Tax exemptions are construed strictly against the claimant. For an entity to claim exemption, it must fall squarely within the terms of the provision granting the privilege.

a. Constitutional Exemptions: Under Section 28(3), Article VI of the Constitution and Section 234(a) of the LGC, exemptions for religious, charitable, and educational institutions require the actual, direct, and exclusive use of the property for such purposes. The use of the property is the determining factor, not the ownership. If a portion of the property is used for commercial or non-exempt purposes, that portion is subject to tax.

b. Statutory Exemptions: Section 234 of the LGC enumerates properties exempt from real property tax, including those owned by the Republic, provinces, cities, municipalities, and barangays, as well as machinery and equipment used for pollution control and environmental protection. Charitable institutions, as defined, are also included.

c. Withdrawal of Exemptions: Section 193 of the LGC is a pivotal provision, stating that tax exemptions granted to all persons, whether natural or juridical, including government-owned or controlled corporations (GOCCs), are withdrawn upon the effectivity of the LGC, except those granted to local water districts, cooperatives registered under R.A. 6938, non-stock and non-profit hospitals and educational institutions, and unless otherwise provided in the LGC. This means that prior statutory tax exemptions in favor of GOCCs or other entities are generally no longer valid unless specifically preserved.

A valid local tax ordinance must comply with the procedural mandates of the LGC, particularly Sections 187 and 188. These include: conducting public hearings prior to enactment; posting of notices and publication of the proposed ordinance; and publication of the full text of the approved ordinance in a newspaper of general circulation or posting in prominent places. Failure to comply with these procedures renders the ordinance null and void. The doctrine of fairness and due process underpins these requirements.

a. Laws:

The 1987 Constitution, Article X and Article VI, Section 28(3).

Republic Act No. 7160, The Local Government Code of 1991, especially Book II.

Related National Tax Laws (National Internal Revenue Code) for preemption analysis.

b. Doctrines and Jurisprudence:

Mactan Cebu International Airport Authority (MCIAA) v. Marcos (G.R. No. 120082, September 11, 1996): Established that the tax exemption of government instrumentalities is withdrawn by Section 193 of the LGC. MCIAA, as a GOCC, became subject to real property tax.

Commissioner of Internal Revenue v. Court of Appeals, Central Board of Assessment Appeals, and National Power Corporation (G.R. No. 106295, July 21, 1994): Affirmed that the constitutional tax exemption of government entities applies only if the government entity is performing governmental functions. If engaged in proprietary functions, it is subject to tax.

Province of Tarlac v. Alcantara (G.R. No. 170626, November 30, 2005): Clarified that for a charitable institution to be exempt under the Constitution and LGC, it must be both non-profit and the property must be actually, directly, and exclusively used for charitable purposes.

City Government of Quezon City v. Bayan Telecommunications, Inc. (BayanTel) (G.R. No. 162015, March 6, 2006): Applied the principle of preemption, holding that the local franchise tax could not be imposed on a telecommunications company whose franchise specifically subjected it to a national franchise tax in lieu of all other taxes.

Philippine Rural Electric Cooperatives Association (PHILRECA) v. The Secretary of the Department of Finance (G.R. No. 262578, September 12, 2023): The Supreme Court En Banc definitively ruled that electric cooperatives registered with the Cooperative Development Authority are exempt from all national and local taxes under Sections 32 and 33 of the Cooperative Code (R.A. 9520), which prevail over the general withdrawal clause in Section 193 of the LGC.

The Secretary of Justice v. Hon. Ralph C. Lantion (G.R. No. 139465, January 18, 2000): Reinforced the mandatory nature of the procedural requirements for enacting tax ordinances under Sections 187 and 188 of the LGC.

a. Administrative Remedies: A taxpayer or affected party must first exhaust administrative remedies. A protest against the assessment of a local tax must be filed with the local treasurer. A petition for review may then be filed with the Local Board of Assessment Appeals (for real property tax) or the appropriate court.
b. Judicial Remedies:

Appeal to the Court of Tax Appeals (CTA): For local tax assessments involving amounts of One Million Pesos (P1,000,000) or more, appeal lies with the CTA.

Action for Declaratory Relief or Injunction: To question the validity or constitutionality of a tax ordinance before it is enforced.

Appeal to the Secretary of Justice: Under Section 187 of the LGC, any question on the constitutionality or legality of a tax ordinance may be appealed to the Secretary of Justice within thirty (30) days from its effectivity. The appeal has a suspensive effect. This is a unique quasi-judicial remedy specific to local ordinances.

Special Civil Action for Certiorari or Prohibition: To assail acts of a local legislative body or executive for grave abuse of discretion amounting to lack or excess of jurisdiction.

c. Prescriptive Periods: Strict adherence to prescriptive periods for filing protests (60 days from receipt of assessment) and appeals is crucial, as failure to comply renders the assessment final and executory.
