Introduction
Understanding the Principle of Strict Interpretation
A Developing but Firm Foundation
Statutory Framework
Common Law Influence
Taxation represents one of the most consequential exercises of state authority. It directly affects both individual livelihoods and the economic vitality of businesses. Yet, as essential as it is, the authority to tax must be carefully constrained by the law. It must be exercised within a legal framework that is clear, fair, and transparent. In instances where the law governing taxation is ambiguous or unclear, a fundamental question arises: Who should bear the burden of such ambiguity, the taxpayer or the tax authority?
The principle firmly established across many jurisdictions, and increasingly recognized in Tanzania, is this: when a taxing statute is ambiguous, it must be interpreted in favor of the taxpayer. This article explores the origins, legal rationale, and current relevance of the rule of strict interpretation in tax law, both in Tanzania and in common law jurisdictions that influence Tanzanian jurisprudence.

Understanding the Principle of Strict Interpretation
Tax statutes are not like other laws. Unlike remedial statutes that extend benefits or protect vulnerable interests, tax laws impose financial burdens. The law, therefore, requires that any such imposition be made in clear, express terms. Where a statute is vague, inconsistently worded, or susceptible to multiple meanings, that ambiguity must not be construed to the detriment of the taxpayer.
This foundational concept is summarized by the Latin maxim in dubio contra fiscum, meaning “when in doubt, against the taxman.” It signifies that no taxpayer should be subject to taxation by implication or administrative assumption. The tax authority may only collect what is clearly and unequivocally imposed by statute.

A Developing but Firm Foundation
Although still developing, Tanzanian jurisprudence has increasingly embraced the principle of strict interpretation in tax matters. Notably, the Court of Appeal has, in several decisions, affirmed this approach. A clear illustration is found in the case of Mantra Tanzania Ltd v. Commissioner General (TRA), Civil Appeal No. 430 of 2020. In this case, the Court emphasized the necessity of interpreting tax statutes strictly.
This case involved the interpretation of provisions related to the source of income for services rendered by non-residents. The Court emphasized that the phrase "services rendered in the United Republic" should be interpreted strictly, focusing on the place where the services are physically performed. The decision highlighted the necessity of adhering to the plain meaning of tax statutes to ensure certainty and fairness in tax administration.
This decision reflects a growing judicial awareness in Tanzania that tax liability must arise from clear statutory language, not from administrative discretion or inferred interpretations.

Statutory Framework
Tanzania’s general legal framework supports this interpretive approach. The Interpretation of Laws Act, Cap. 1 R.E. 2019, is particularly instructive. Section 29 of the Act provides that statutes must be interpreted in accordance with the clear intention of Parliament. This prohibits tax authorities and courts from extending meanings or assumptions beyond what the law plainly states.
Although Tanzanian tax statutes do not always expressly adopt the in dubio contra fiscum maxim, the broader statutory context clearly favors an interpretive approach that protects taxpayers from unclear legal burdens.

Common Law Influence
Tanzania’s legal system, as part of the common law tradition, often draws interpretive guidance from established English and Commonwealth jurisprudence. Several landmark cases continue to be highly influential:
In Partington v. Attorney-General (1869) LR 4 HL 100, the House of Lords stated, “If the person sought to be taxed comes within the letter of the law, he must be taxed. If not, he must not be taxed. In a taxing Act one has to look merely at what is clearly said.”
This statement remains foundational in tax law, affirming that tax must be imposed only where the law clearly applies.
Likewise, in Cape Brandy Syndicate v. Inland Revenue Commissioners [1921] 1 KB 64, Rowlatt J famously stated: “In a taxing Act, one has to look at what is clearly said. There is no room for any intendment. Nothing is to be read in, nothing is to be implied. One can only look fairly at the language used.”
These decisions are routinely cited by East African courts and serve as persuasive authority in Tanzanian legal reasoning, particularly in cases where local precedent is limited or emerging.
Why the Principle Matters
The rule of strict interpretation in tax law is not a technicality, it is a critical safeguard within the broader legal system. Its importance can be summarized across three dimensions;
Protection of Taxpayer Rights; it ensures that individuals and businesses are not subject to arbitrary or unforeseen tax liabilities. It upholds the principle that no one should be punished or penalized based on vague or uncertain legal standards.
Limitation of Administrative Overreach; it acts as a check against the discretionary power of tax authorities. Tax administrators must adhere to the express language of the statute and may not enforce unwritten rules or implied restrictions.
Promotion of Legal Certainty and the Rule of Law; this principle reinforces the foundational constitutional idea that taxation is a matter of law, not of policy or executive discretion. Only Parliament has the authority to create tax obligations. Where the law is silent or unclear, the benefit must go to the governed, not the governing.
Conclusion
As Tanzania continues to modernize its tax administration and refine its jurisprudential approach, courts and quasi-judicial bodies must continue to uphold the principle of strict interpretation. Taxation must not become a matter of convenience for the revenue authority, nor should ambiguities in the law be used as tools for aggressive revenue collection.
The clarity, fairness, and predictability of tax laws are essential for fostering public trust and voluntary compliance. Resolving ambiguities and contradictions in favor of the taxpayer is not merely a matter of leniency, it is a constitutional necessity grounded in the rule of law.
When in doubt, favor the taxpayer. This is not just a legal rule, it is a commitment to just, lawful, and democratic taxation.
