Tan vs. Del Rosario, Jr.

Republic Act No. 7496 (SNIT) is constitutional and does not violate the one-subject-one-title rule, the uniformity and equality clause, or due process; general professional partnerships are not taxable entities, and partners are subject to income tax in their individual capacities computed on their distributive shares of partnership profits, rendering Section 6 of Revenue Regulations No. 2-93 valid.

The case arose from the enactment of R.A. No. 7496, which amended the National Internal Revenue Code to establish the Simplified Net Income Taxation Scheme for self-employed individuals and professionals. This scheme simplified tax computation by limiting allowable deductions to specific direct costs or a flat 40% of gross receipts, representing a legislative shift toward a schedular approach for individual taxpayers. Professionals and law firms challenged the law’s validity and the administrative regulation applying it to partners in general professional partnerships, claiming violations of constitutional provisions on legislative procedure, uniformity in taxation, and due process, as well as excess of administrative authority.

• Republic Act No. 7496, entitled "An Act Adopting the Simplified Net Income Taxation Scheme For The Self-Employed and Professionals Engaged In The Practice of Their Profession, Amending Sections 21 and 29 of the National Internal Revenue Code, as Amended," amended the Tax Code to simplify income taxation for self-employed individuals and professionals.
• Section 21(f) was introduced, imposing tax on the taxable net income of self-employed individuals and professionals using a schedular rate system ranging from 3% to 30% based on income brackets.
• Section 29 was amended to limit allowable deductions for taxpayers under the scheme to specific direct costs, including raw materials, supplies, direct labor, salaries of directly engaged employees, utilities, business rentals, depreciation, calamity contributions, and interest on certain loans; alternatively, taxpayers could deduct 40% of gross receipts if direct costs were difficult to determine.
• Petitioner Rufino R. Tan claimed the title of the bill was deficient and that the law shifted from net income to gross income taxation, violating constitutional provisions on uniformity, equity, and due process by allegedly discriminating against individual professionals compared to corporations.
• Petitioners in the second case, a law firm and individual partners, assailed Section 6 of Revenue Regulations No. 2-93, which applied the Simplified Net Income Taxation Scheme to general professional partnerships and their partners, arguing the regulation exceeded administrative authority and contradicted legislative intent that the law applied only to individuals, not partnerships.
• The Solicitor General defended the statute and regulation, asserting valid legislative classification and the rule that general professional partnerships are not taxable entities but flow-through mechanisms where partners are taxed individually.
• Section 23 of the National Internal Revenue Code, unamended by R.A. No. 7496, explicitly provides that general professional partnerships are not income taxpayers and that partners are liable for tax only in their individual capacity on their distributive shares of profits.

• The title of House Bill No. 34314, which became Republic Act No. 7496, is a misnomer or deficient for being merely entitled "Simplified Net Income Taxation Scheme for the Self-Employed and Professionals Engaged in the Practice of their Profession," allegedly violating Article VI, Section 26(1) of the Constitution requiring every bill to embrace only one subject expressed in the title.
• Republic Act No. 7496 violates Article VI, Section 28(1) of the Constitution requiring taxation to be uniform and equitable, because it allegedly shifts from net income to gross income taxation for self-employed individuals and professionals while treating them differently from corporations and ordinary partnerships subject to the global tax system.
• The law violates Article III, Section 1 of the Constitution guaranteeing due process and equal protection, because the classification results in unequal tax liabilities between individual professionals and corporate taxpayers, and potentially amounts to confiscatory taxation.
• Section 6 of Revenue Regulations No. 2-93 is invalid because public respondents exceeded their rule-making authority by applying the Simplified Net Income Taxation Scheme to general professional partnerships, contrary to legislative deliberations showing Congressional intent to apply the law only to individuals and not to corporations or partnerships.
• Expenses paid by partners in their individual capacities that are not reimbursed by the partnership but are not considered direct costs should remain deductible from gross income, and the regulation’s limitation on such deductions is unlawful.

• The title of Republic Act No. 7496 is sufficient and complies with the constitutional requirement as it fairly apprises the people of the single subject matter, which is the simplified net income taxation scheme for self-employed and professionals, and need not be a compendium of the entire law.
• The classification between individual taxpayers subject to the schedular approach and corporations subject to the global approach is valid and not arbitrary, satisfying the requirements that standards are substantial, germane to the legislative purpose, applicable to present and future conditions, and equal to all within the class.
• The legislature possesses plenary discretion to determine the nature, object, extent, coverage, and situs of taxation, and courts will not interfere unless the tax measure is confiscatory or violates specific constitutional limitations, which is not present in this case.
• Section 6 of Revenue Regulations No. 2-93 merely confirms the existing rule under Section 23 of the National Internal Revenue Code that general professional partnerships are not income taxpayers but flow-through entities, and that partners are taxed individually on their distributive shares, making the application of the Simplified Net Income Taxation Scheme to partners proper and consistent with the law.
• There is no distinction in income tax liability between a person practicing a profession individually and one doing so through a general professional partnership, as both are ultimately taxed as individuals under the same schedular system applicable to non-compensation income.

• Procedural Issues: N/A.
• Substantive Issues: Whether Republic Act No. 7496 violates Article VI, Section 26(1) of the Constitution on the one-subject-one-title rule; whether Republic Act No. 7496 violates the uniformity and equality clause under Article VI, Section 28(1) and the equal protection clause under Article III, Section 1 of the Constitution; whether Republic Act No. 7496 violates due process; and whether Section 6 of Revenue Regulations No. 2-93 is a valid exercise of administrative authority or exceeds the rule-making power by applying the Simplified Net Income Taxation Scheme to general professional partnerships.

• Procedural: N/A.
• Substantive: The Court held that Republic Act No. 7496 does not violate the one-subject-one-title rule because the title sufficiently expresses the single subject of adopting a simplified net income taxation scheme for self-employed and professionals. The law does not violate the uniformity and equality clause or equal protection because the classification between individual taxpayers subject to a schedular approach and corporations subject to a global approach is based on substantial standards, germane to the legislative purpose of simplifying tax administration for individuals, and applies equally to all within each class. The law does not violate due process because it is not confiscatory and the legislature acted within its wide discretion in tax matters. Section 6 of Revenue Regulations No. 2-93 is valid because it merely confirms the standing rule under Section 23 of the National Internal Revenue Code that general professional partnerships are not taxable entities but merely flow-through mechanisms, and partners are liable for income tax in their individual capacity computed on their distributive shares of profits, subject to the same deduction limitations under the Simplified Net Income Taxation Scheme applicable to all individual taxpayers deriving non-compensation income.

• Uniformity and Equality in Taxation and Equal Protection — Defined as requiring that all subjects or objects of taxation similarly situated be treated alike both in privileges and liabilities; classification is permitted provided the standards are substantial and not arbitrary, the categorization is germane to the legislative purpose, the law applies to both present and future conditions, and the classification applies equally to all within the same class; applied to uphold the differential tax treatment between individual taxpayers under the schedular system and corporations under the global system.
• Legislative Discretion in Taxation — The legislature possesses primary discretion to determine the nature, object, extent, coverage, and situs of taxation; judicial review is limited and courts will not invalidate tax measures unless they are confiscatory, unjust, or violate specific constitutional limitations.
• General Professional Partnerships as Flow-Through Entities — General professional partnerships are not income taxpayers under the National Internal Revenue Code; the partnership is merely a mechanism for generating and distributing income to partners who are individually liable for income tax on their distributive shares computed as individual taxpayers.
• Schedular versus Global Approach to Income Taxation — The schedular approach varies tax treatment depending on the kind or category of taxable income, while the global approach treats all categories of taxable income indifferently under common rules; the Court recognized the legislative intent to shift toward a schedular approach for individual taxpayers while maintaining the global treatment for taxable corporations.
• One-Subject-One-Title Rule — The constitutional requirement aims to prevent log-rolling legislation, avoid fraud upon the legislature, and fairly apprise the people of the subjects of legislation; the title need not be a complete index or compendium of the law’s contents but must fairly indicate the general subject matter.

• "Uniformity of taxation, like the kindred concept of equal protection, merely requires that all subjects or objects of taxation, similarly situated, are to be treated alike both in privileges and liabilities."
• "Uniformity does not forfend classification as long as: (1) the standards that are used therefor are substantial and not arbitrary, (2) the categorization is germane to achieve the legislative purpose, (3) the law applies, all things being equal, to both present and future conditions, and (4) the classification applies equally well to all those belonging to the same class."
• "With the legislature primarily lies the discretion to determine the nature (kind), object (purpose), extent (rate), coverage (subjects) and situs (place) of taxation."
• "The general professional partnership is deemed to be no more than a mere mechanism or a flow-through entity in the generation of income by, and the ultimate distribution of such income to, respectively, each of the individual partners."
• "Anything else would be to require a virtual compendium of the law which could not have been the intendment of the constitutional mandate."

• Pepsi Cola vs. City of Butuan — Cited for the standards validating classification in taxation.
• Basco vs. PAGCOR — Cited for the standards of valid classification in taxation.

• Constitution, Article VI, Section 26(1) — Cited regarding the one-subject-one-title rule; the Court upheld the title of R.A. No. 7496 as sufficient to meet this requirement.
• Constitution, Article VI, Section 28(1) — Cited regarding the requirement that taxation be uniform and equitable and that Congress evolve a progressive system; the Court upheld the classification between individual and corporate taxpayers as valid and uniform.
• Constitution, Article III, Section 1 — Cited regarding due process and equal protection; the Court found no violation as the tax measure was not confiscatory and the classification was valid.
• National Internal Revenue Code, Section 21 — As amended by R.A. No. 7496, establishing the Simplified Net Income Taxation Scheme for self-employed and professionals with specific tax schedules.
• National Internal Revenue Code, Section 23 — Cited to establish that general professional partnerships are not taxable entities and that partners are taxed individually on their distributive shares.
