Philippines Republic Act 12253 — Enhanced Fiscal Regime for Large-Scale Metallic Mining Act

Mechanism

RA 12253 amends Sections 34(B), 287, and Title VI / Chapter VII of RA 8424 (National Internal Revenue Code of 1997, as amended) and inserts new Sections 151-A through 151-D and 287-A. The key fiscal levers are:

• Margin-based royalty (outside mineral reservations): A five-tier

schedule scaling from 1% to 5% on the margin between income from mining operations and gross output (margin brackets running 0–10%, 10–20%, 20–40%, 40–60%, >60%). A 0.1% floor royalty applies to operations with margins below 1%. Mines inside mineral reservations remain at the 5% flat royalty established under DENR AO 2018-19.

• Windfall-profits tax: A separate five-tier WPT of 1% to 10% on

income above a 30% margin, layered on top of corporate income tax and the royalty.

• Ring-fencing: Each mining agreement is treated as a separate

taxable entity. Contractors operating multiple projects can no longer net losses on one mine against profits on another — closing a longstanding leakage in the current regime.

• Income-tax holiday for new projects: New mining projects qualify

for an ITH followed by transition to the 20% reduced CIT rate established under the CREATE / CREATE MORE reforms.

• Transparency mechanisms: Statutory codification of EITI-style

multi-stakeholder reporting requirements and earmarking of a portion of revenues to host LGUs and IP communities.

DOF issued the implementing rules within 90 days of signing; all existing large-scale metallic mining operations transitioned to the new fiscal terms 150 days after effectivity, on 17 February 2026.

Downstream implications

• Government take rises materially on boom-cycle margins. Estimated

PHP 25.08 bn additional revenue across 2026–2029 (avg PHP 6.26 bn/yr), but the windfall tier means actual receipts skew sharply higher in high-nickel-price years. This is a structural transfer of upside from contractors to fiscus.

• **Repositions the Philippines as a critical-minerals supplier with

EITI-style governance overlay.** The country is the world's #2 nickel producer; the new regime is explicitly framed by DOF and EITI as positioning Philippine output for ex-China energy-transition supply chains (US IRA-eligible critical-minerals sourcing, EU CRMA strategic-project status).

• Ring-fencing is the bigger compliance shock for incumbents than

the headline rates. Conglomerate miners that previously cross-credited losses (exploration costs, legacy mine rehabilitation) against profitable mines now face per-project tax computation.

• Distinct from CREATE MORE (RA 12066, already filed). RA 12253 is

a sector-specific fiscal-regime overhaul under the NIRC; CREATE MORE is a horizontal CIT and incentive reform. The two interact (the 20% reduced CIT and ITH mechanics ride on CREATE MORE) but the mining royalty + WPT structure is statutorily unique to RA 12253.

Open questions

• Effective date of full-rate application: PwC and DivinaLaw flag that

certain transitional provisions apply to MPSAs (Mineral Production Sharing Agreements) signed before effectivity — the operative blanket date of 17 February 2026 may admit project-level exceptions pending DOF-DENR joint clarification.

• Pass-through to Indonesian and Chinese nickel-pig-iron / NPI smelter

margins: if Philippine NPI feedstock costs rise on the WPT pass-through, expect short-term reshuffling of seaborne nickel-ore flows toward Indonesian processors with captive mines.

• Whether the regime triggers any constitutional challenge under the

1987 Constitution's "regalian doctrine" framework or under existing Financial or Technical Assistance Agreements (FTAAs) — DivinaLaw notes possible legacy-contract litigation risk.
