As someone who has worked closely with both the government and the private sector, I view the new fiscal regime as an important step towards aligning the mining sector with global standards of transparency, progressivity, and shared prosperity. However, the question remains: Will it truly deliver a fair, competitive, and administratively feasible tax system?

This discussion focuses on the fiscal dimension of the mining reform introduced by Republic Act No. 12253 — particularly its implications on tax policy, administration, and compliance.

A Complex But Fair Tax Regime

RA 12253 introduces a mixed use of Gross and Margin-Based Taxation which may have its pros and cons. The move from gross output taxation to margin-based royalties is a rational step — it links government take to profitability, not production volume, resulting to risk and financial sharing between the government and the mining company who are, to my mind, joint venturers in this undertaking. This corrects a long-standing distortion where miners paid the same even in downturns. However, margin-based taxation complicates compliance and implementation especially so in a mixed gross and net income-based taxation. Also, under this set-up, the revenue take by the government can be erratic, not stable. The table below summarizes the new tax regime for mining companies:

Under the new structure, royalties outside mining reservations and windfall profits are net-based, while royalties inside reservations, the minimum royalty, and the LGU business tax are computed on gross output. This mix presents most notable pros and cons.

The royalty inside mining reservations is set at 5% of gross output. This is a gross-based levy that is simple and straightforward to compute, but it is regressive, as it ignores profitability. By contrast, the royalty outside mining reservations ranges from 1 to 5% depending on the profit margin. This is net- or margin-based, making it progressive, fair, and rational, although it is more complex to compute.

A new Windfall Profits Tax (WPT) is imposed at 1 to 10% of net margin which is payable only during high-profit periods. On the reverse, a minimum royalty of 0.10% of gross output is imposed when operations are low such as when the margin is 0% or less.

In implementing a mixed-based taxation, there is a need to address or tackle several concerns.

First, there is concern on the Administrative and Implementation Readiness. As announced by DOF and BIR, they will start drafting the regulations and conduct public hearings by November and the regulations are to be released by December this year in compliance with the law.

But, is the BIR fully equipped to implement and monitor a margin-based royalty and WPT system — both of which demand robust audit capacity, precise cost allocation, and real-time price validation mechanisms?

The WPT is new and is particularly complex, as it depends on fluctuating metal prices and variable operating costs. Without clear technical rules and upgraded systems, disputes on what constitutes ‘net income from metallic operations’ are inevitable. Along this line, the BIR should consider issuing comprehensive guidelines on prices, allowable deductions, cost attribution, and timing of recognition to ensure consistency and minimize interpretive conflicts.

Equally important is aligning this new fiscal regime on mining with the existing regular tax regime. There are various items that need clarity as the new mining regime interfaces with the computation of annual corporate income tax, VAT, business taxes, among others. How will the new mining-specific levies co-exist with corporate income tax, local business taxes, and other imposts — particularly for consolidated entities with both mining and non-mining operations? How does it interface with the computation of the regular income tax which is entity-based considering the ring-fencing requirement? In the same manner, there should be clarity on the deductibility of royalties and WPT from income tax. Likewise, there is a need to align BIR forms and schedules for quarterly and annual filings.

Another key concern is the Minimum Royalty for Loss-Making Projects. The minimum 0.10% royalty on gross output may penalize further loss-making operations that may severely impact the sustainability of the operations. Perhaps the government can grant the same relief or means of recovery as that in Minimum Corporate Income Tax (MCIT) and NOLCO which are allowed to be credited against future tax payments or can be carried forward as a deduction benefiting future tax liabilities.

The new mining law adopts anti-avoidance measures (ring fencing, transfer pricing and thin capitalization rules) to avert shifting or sharing of revenues resulting in lower royalty payments. Of particular attention is transfer pricing. There is a need to put in place a robust mechanism and real-time price validation as well as risk identification, allocation, or data sharing for the BIR to fully implement an honest-to-goodness transfer pricing audit. For example, what tools will BIR and BOC use to validate export prices and detect transfer pricing among affiliates? Will real-time data from Mining and Geosciences Board (MGB) or customs be integrated? An inter-agency data sharing, real-time invoice tracking, are necessary.

In summary, I have the following suggested focus areas for BIR to consider: 1. implementation readiness and staff training; 2. administrative feasibility and audit capacity for the WPT; 3. transfer pricing and ring fencing; 4. clear guidelines on areas interfacing with current regular tax regime, especially on margin computation, deductibility of royalties and windfall profits, and cost attribution; 5. clarity on the recoupment mechanisms for losses and minimum royalty payments under NOLCO and MCIT in the current tax regime; and 6. investor safeguards, policy and rules/implementation stability, and long-term consistency.

Automatic LGU revenue release is good but there is concern on weak LGU absorptive capacity.

Direct and timely release of the 40% LGU share is an excellent provision to promote local empowerment — provided it is accompanied by fiscal discipline and absorptive capacity-building. Despite improved revenue disbursements, many local governments lack the capacity to manage large funds effectively, risking misallocation without enhanced fiscal transparency and national government support and planning.

Consider a Balanced Ring-fencing and Anti-avoidance Measures

The law’s provisions on ring-fencing, thin capitalization, and transfer pricing reflect a more mature and disciplined tax regime. Treating each mining project as a separate taxable entity promotes transparency and prevents cross-subsidization, while the related-party and thin capitalization rules safeguard the tax base from profit shifting and artificial deductions.

However, ring fencing may reduce investment flexibility which may discourage exploration and expansion and may dis-incentivize smaller and newer projects to come in as they struggle financially without group support. Strict ring-fencing results to inefficiency limiting economies of scale or underutilization of capital.

Thus, the government may consider a balanced ring fencing in its application. For example, it can be on a phased or gradual implementation, or a targeted application, or allow transitional provisions. The IRR can perhaps authorize the Secretary of Finance to lay down situations or instances when ring fencing may be suspended, or applied gradually, or partially like allowing loss offsetting among projects for a limited time especially during the early stage of cost recovery.

A balanced ring-fencing framework that protects public revenue without penalizing or disincentivizing legitimate business operations is encouraged.

Closing Reflection

RA 12253 is a milestone in balancing fiscal prudence, environmental stewardship, and community participation. The real challenge lies not in what the law says — but in how faithfully and intelligently it will be implemented.
