I. This memorandum addresses the foundational principle in Philippine taxation that tax exemptions are construed strictly against the taxpayer and in favor of the State, known as the rule of strictissimi juris. This doctrine imposes a heavy burden of proof upon any entity or person claiming a privilege from the general obligation to pay taxes.
II. The legal basis for this rule is rooted in the principle that taxes are the lifeblood of the government, essential for its continued operation and the provision of public services. Consequently, statutes granting tax exemptions are considered a derogation of sovereign authority and must be clear, categorical, and unequivocal. Any doubt or ambiguity in the language of the exemption is resolved not in favor of the grantee, but in favor of the State.
III. The Supreme Court has consistently held that he who claims an exemption must justify it by words too plain to be mistaken and too categorical to be misinterpreted. The burden of proof rests solely and conclusively on the claimant to establish every element of the exemption, including a clear grant by statute and that the claimant falls squarely within its terms. This is in stark contrast to tax laws themselves, which are liberally construed in favor of the taxpayer where there is doubt.
IV. The rule of strictissimi juris applies to all types of tax exemptions, whether they pertain to income tax, value-added tax, property tax, or excise tax. It governs exemptions claimed by both natural and juridical persons, including private corporations and, with notable but limited exceptions, non-stock, non-profit entities.
V. A critical application of this rule is that tax exemptions are personal to the grantee. They are not transferable unless the statute expressly provides for transferability. Furthermore, an exemption granted to a specific class of entities or for a specific purpose cannot be extended by implication to other entities or purposes, no matter how analogous they may seem.
VI. The rule admits of exceptions, but these exceptions are themselves strictly construed. The most significant exception is for exemptions granted to the Republic of the Philippines, its political subdivisions, and government-owned or controlled corporations (GOCCs) performing governmental functions. However, even GOCCs engaged in proprietary functions are subject to tax unless specifically exempted. Another traditional exception is for religious, charitable, and educational institutions, but they must still prove strict compliance with the conditions set by law, such as the actual, direct, and exclusive use of assets for stated purposes.
VII. In litigation, the Commission on Internal Revenue (BIR) is accorded the presumption of correctness in its assessments. A taxpayer asserting an exemption effectively assumes the role of a plaintiff and must overcome this presumption with clear and convincing evidence. The BIR’s interpretation of a tax statute, while not conclusive, is generally given great weight by the courts.
VIII. Failure to discharge the burden of proof under the strictissimi juris rule results in the denial of the exemption claim. The taxpayer remains liable for the deficiency tax assessment, plus corresponding surcharges, interests, and penalties as provided by the National Internal Revenue Code. The defense of good faith or honest belief is unavailing against the strict application of the law.
IX. Practical Remedies. To successfully navigate this stringent doctrine, a claimant should: (a) Scrutinize the enabling law, charter, or treaty provision for the precise and literal language of the exemption grant; (b) Ensure all documentary evidence proving entitlement (e.g., Articles of Incorporation, Securities and Exchange Commission certification, proof of actual activities, financial statements) is complete, authentic, and readily available; (c) Secure a definitive ruling from the BIR, such as a Private Ruling or a Tax Treaty Relief Application, prior to engaging in the transaction or claiming the exemption on a return; (d) In case of a BIR assessment, respond promptly with a detailed protest supported by certified true copies of all relevant documents, meticulously linking each piece of evidence to a specific requirement of the exemption law; and (e) Consider availing of tax amnesty programs, when available, as a final alternative to extinguish tax liability arising from a disallowed exemption, albeit with payment of a set percentage and waiver of the right to contest.
