12.1 National Tax Allotment (NTA, Mandanas-Garcia Ruling) and Allocation Formulas

12.1 National Tax Allotment (NTA, Mandanas-Garcia Ruling) and Allocation Formulas

Quick Answer: The National Tax Allotment (NTA)—formerly known as the Internal Revenue Allotment (IRA)—represents the constitutional "just share" of local government units (LGUs) in national taxes under Article X, Section 6 of the 1987 Constitution. Following the landmark Supreme Court ruling in Mandanas-Garcia v. Ochoa (G.R. Nos. 199802 & 208488), the tax base was expanded beyond Bureau of Internal Revenue (BIR) collections to encompass all national taxes, including customs duties collected by the Bureau of Customs (BOC). Under Section 284 of Republic Act No. 7160 (The Local Government Code of 1991), the NTA is fixed at 40% of gross national tax collections of the third (3rd) fiscal year preceding the current fiscal year. The total pool is distributed vertically across tiers (Provinces 23%, Cities 23%, Municipalities 34%, Barangays 20%) and horizontally within each tier (Population 50%, Land Area 25%, Equal Sharing 25%). Releases are automatic and monthly, without need for executive approval or administrative lien.

1. Constitutional Foundation and Historical Evolution (IRA to NTA)

Intergovernmental fiscal transfers serve as the financial lifeblood of Philippine local autonomy. While the Local Government Code grants broad taxing powers to provinces, cities, municipalities, and barangays, local tax bases remain unevenly distributed across the archipelago. The constitutional framers recognized that without substantial, predictable transfers from the national treasury, genuine local self-governance would remain an unfulfilled aspiration.

The Constitutional Mandate

Article X, Section 6 of the 1987 Philippine Constitution explicitly establishes:

"Local government units shall have a just share, as determined by law, in the national taxes which shall be automatically released to them."

This constitutional guarantee establishes two non-negotiable legal principles:

1. Substantive Entitlement: LGUs possess an inalienable right to a "just share" in all taxes levied by the national sovereign.
2. Procedural Protection: Such shares must be released automatically, shielding local finances from partisan political leverage, executive impoundment, or discretionary bureaucratic delays.

Historical Precedents

Prior to the 1987 Constitution, intergovernmental transfers were governed by Presidential Decree No. 144 (1973) under the martial law regime. PD 144 allocated an allotment not exceeding 20% of national internal revenue taxes, distributed through a discretionary and centralized mechanism that severely curtailed local administrative independence.

With the enactment of Republic Act No. 7160 (The Local Government Code of 1991), Congress fulfilled the constitutional mandate by enacting Title Three, Chapter 1 (Sections 284 to 288). Section 284 progressively elevated the local government share to 40%, codifying the mechanism historically designated as the Internal Revenue Allotment (IRA).

2. Landmark Jurisprudence: The Mandanas-Garcia Doctrine

For nearly three decades following the passage of RA 7160, the national government calculated the IRA based exclusively on collections made by the Bureau of Internal Revenue (BIR) under the National Internal Revenue Code (NIRC). Collections made by the Bureau of Customs (BOC) and other agencies were systematically excluded.

This restrictive practice was challenged before the Supreme Court in two consolidated landmark petitions:

• Congressman Hermilando I. Mandanas, et al. v. Executive Secretary Paquito N. Ochoa, Jr., et al. (G.R. No. 199802)
• Hon. Enrique T. Garcia, Jr. v. Executive Secretary Paquito N. Ochoa, Jr., et al. (G.R. No. 208488)

The Legal Issue

The petitioners argued that Section 284 of RA 7160 unconstitutionally narrowed the constitutional base by inserting the qualifying word "internal" into the statutory phrasing:

$\text{Section 284 Phrasing:} \quad \text{"\dots a forty percent (40\%) share in the national } \mathbf{internal} \text{ revenue taxes\dots"}$

They contended that Article X, Section 6 of the 1987 Constitution explicitly mandates a just share in "national taxes", not merely "national internal revenue taxes".

The Supreme Court Ruling

On July 3, 2018 (reaffirmed upon motion for reconsideration on April 10, 2019), the Supreme Court en banc delivered a historic verdict:

1. Unconstitutionality of Textual Restriction: The Supreme Court declared the phrase "internal revenue" in Section 284 of RA 7160 unconstitutional. The Court ruled that Congress exceeded its constitutional authority when it limited the tax base to internal revenue taxes.
2. Expansive Base of National Taxes: The Court ruled that the constitutional phrase "national taxes" encompasses all collections gathered by national collecting agencies pursuant to national tax statutes, including:
   • National internal revenue taxes collected by the BIR under the NIRC;
   • Customs tariffs, import duties, and excise taxes collected by the Bureau of Customs (BOC);
   • Fifty percent (50%) of value-added taxes collected in the Autonomous Region in Muslim Mindanao (now BARMM);
   • Sixty percent (60%) of national taxes collected within Special Economic Zones (PEZA ecozones) under RA 7916;
   • Port fees, energy taxes, and other levies imposed by national law.
3. Prospective Application & Renaming to NTA: The Supreme Court directed that the expanded base be implemented prospectively starting with the 2022 budget cycle (FY 2022). To accurately reflect the broadened revenue base, the Department of Budget and Management (DBM) and the Department of Finance formally transitioned the operational nomenclature from Internal Revenue Allotment (IRA) to National Tax Allotment (NTA).
4. Executive Order No. 138 (s. 2021): To match this substantial fiscal expansion—which increased local allotments by over 30%—the national government issued EO 138, mandating the full devolution of devolved functions (e.g., local health facilities, agricultural extension services, communal irrigation, social welfare programs) from national executive departments to LGUs.

3. Statutory Computation Formula and the 3rd Preceding Year Rule

Section 284 of RA 7160 establishes the mathematical baseline for computing the aggregate national allotment:

$\text{Total NTA Pool} = 40\% \times \text{Gross National Tax Collections of the 3rd Preceding Fiscal Year}$

Why the Third (3rd) Preceding Fiscal Year?

A central technical question frequently tested on the BCLTE is why the computation is anchored to the third preceding year ($t-3$) rather than the immediately preceding year ($t-1$) or current year ($t$).

The rationale stems from the audit and budget formulation timetable of Philippine public finance:

• Year $t-3$ (Collection Cycle): Taxes are collected throughout the fiscal year by the BIR, BOC, and other agencies.
• Year $t-2$ (Audit & Reconciliation Cycle): The collecting agencies close their accounting ledgers. The Bureau of the Treasury (BTr) consolidates the cash reports, and the Commission on Audit (COA) completes its statutory financial audit, officially certifying the gross national tax collections.
• Year $t-1$ (Budget Formulation Cycle): The Development Budget Coordination Committee (DBCC) uses the COA- and BTr-certified collections of Year $t-3$ to determine the exact NTA ceiling. The DBM issues the annual Local Budget Memorandum (LBM) informing all LGUs of their precise allotment shares, allowing LGUs to formulate their Annual Budgets during the third quarter of Year $t-1$.
• Year $t$ (Budget Execution Cycle): The General Appropriations Act (GAA) takes effect on January 1, and the NTA is automatically disbursed monthly to LGUs.

The Deficit Reduction Exception

Under Section 284, if the national government incurs an unmanageable public sector deficit, the President of the Philippines is authorized to effect a temporary reduction in the NTA. However, this power is subject to strict statutory limitations:

• It requires the joint recommendation of the Secretary of Finance, the Secretary of Budget and Management, and the Secretary of the Interior and Local Government;
• Consultations must be conducted with the presiding officers of both houses of Congress and the presidents of the local government leagues;
• In no case shall the reduced allotment be less than thirty percent (30%) of national tax collections of the third preceding fiscal year.

4. Vertical Allocation Across LGU Tiers (Section 285)

Once the aggregate national NTA pool is calculated, Section 285 of RA 7160 governs how that total amount is apportioned vertically among the four institutional tiers of local government:

Total National Tax Allotment (100%)
├── Municipalities: 34%
├── Provinces:      23%
├── Cities:         23%
└── Barangays:      20%

BCLTE Exam Tip: Candidates often mistakenly assume cities receive the largest vertical share due to economic size. Remember that Municipalities receive the largest vertical share at 34%, while Provinces and Cities receive equal shares of 23% each.

5. Horizontal Internal Distribution Formula (Section 285)

After dividing the NTA pool vertically into the four tier sub-funds, how is the money allocated horizontally among individual local units within each tier (e.g., among all 82 provinces, among all 149 cities, or among all 1,480+ municipalities)?

Section 285 prescribes an identical mathematical formula for Provinces, Cities, and Municipalities:

Mathematical Formulation

For any individual LGU within a given tier (province, city, or municipality), its annual NTA is calculated as:

$\text{NTA}_{\text{LGU}} = \left( \frac{\text{Pop}_{\text{LGU}}}{\text{Total Pop}_{\text{Tier}}} \times 0.50 \times \text{Tier Pool} \right) + \left( \frac{\text{Area}_{\text{LGU}}}{\text{Total Area}_{\text{Tier}}} \times 0.25 \times \text{Tier Pool} \right) + \left( \frac{0.25 \times \text{Tier Pool}}{N_{\text{Tier}}} \right)$

Special Distribution Rule for Barangays

Pursuant to Section 285(d) of RA 7160, the horizontal allocation for the 20% barangay pool follows a modified two-step process:

1. Basic Guaranteed Share: Every barangay with a population of not less than one hundred (100) inhabitants is entitled to a minimum basic allocation of ₱80,000 per annum.
2. Distribution of Balance: The remaining balance of the barangay tier pool after deducting the aggregate basic guaranteed shares is distributed according to:
   • Population: Sixty percent (60%)
   • Equal Sharing: Forty percent (40%)

6. Automatic Release and Fund Governance Protocols

Sections 286 and 287 of RA 7160 provide robust institutional safeguards to ensure that local allotments are insulated from political manipulation and channelled toward capital formation.

The Automatic Release Mechanism (Section 286)

• Monthly Direct Disbursement: The national government must disburse the NTA shares to LGUs on a monthly basis, strictly within the first five (5) business days of each month.
• Direct Deposit: Funds are credited directly by the Bureau of the Treasury (BTr) via electronic fund transfers to the LGU's depository accounts maintained with Authorized Government Depository Banks (AGDBs)—specifically Land Bank of the Philippines (LBP) and the Development Bank of the Philippines (DBP).
• Absolute Non-Lien Guarantee: Section 286 categorically dictates that the NTA "shall not be subject to any lien or holdback that may be imposed by the national government for whatever purpose". National agencies, the DBM, and depository banks are strictly prohibited from deducting administrative costs, withholding transfers as political penalties, or unilaterally intercepting allotments to settle disputed debts.

The 20% Development Fund Earmark (Section 287)

Pursuant to Section 287 of RA 7160:

"Each local government unit shall appropriate in its annual budget no less than twenty percent (20%) of its annual national tax allotment for development projects."

Joint Memorandum Circulars (JMCs) issued by the DILG and DBM govern the utilization of this 20% Development Fund (DF). Under these regulations:

• The 20% DF must finance capital investment programs, infrastructure development, socio-economic development, and environmental management.
• Strict Prohibitions: The 20% DF cannot be spent on personal services (salaries, honoraria, bonuses), administrative overhead, routine office supplies, travel expenses, purchase of administrative passenger cars, or financing political festivities.
