Can the President Suspend Fuel Excise Taxes in the Philippines?

News hook: In April 2026, President Marcos issued Executive Order No. 144 suspending excise taxes on LPG and kerosene after oil prices surged past USD $93 per barrel during the 2026 Philippine energy crisis — the first use of new powers granted by Republic Act No. 12316, signed just weeks earlier on March 25, 2026.

Legal question

Does the President of the Philippines have legal authority to suspend or reduce excise taxes on petroleum products without a new act of Congress — and if so, under what conditions and limits does that authority operate?

Applicable laws and rules

Republic Act No. 12316 (2026) — An Act Authorizing the President to Suspend or Reduce Excise Tax on Petroleum Products, amending Section 148 of the NIRC. Signed March 25, 2026.
National Internal Revenue Code of 1997 (NIRC), Section 148 — The primary statutory provision setting specific excise tax rates on petroleum products, as originally enacted under RA 8424 and last substantively amended by the TRAIN Law.
Republic Act No. 10963 — TRAIN Law (2017), Section 43 — Imposed phased petroleum excise tax increases for 2018–2020 and included a built-in $80/barrel suspension clause limited to that period, which lapsed after 2020 without ever being activated.
1987 Philippine Constitution, Article VI, Section 28(2) — The constitutional basis allowing Congress to delegate to the President the power to fix tariff rates, import/export quotas, and other duties within specified limits.
Executive Order No. 144, Series of 2026 — Signed April 16, 2026; the first exercise of RA 12316 authority, suspending excise taxes on LPG and kerosene for three months.
Revenue Regulations No. 03-2026 and Revenue Memorandum Circular No. 31-2026 — BIR implementing rules for the EO 144 suspension, effective April 17, 2026.

Why this matters

Fuel prices directly affect the cost of living for every Filipino household. Excise taxes embedded in petroleum prices flow through to jeepney fares, electricity generation, farm inputs, cooking gas, and the price of nearly every consumer good transported by road. When global oil prices spike — as they did in 2026 when the Strait of Hormuz disruption drove crude to nearly USD $94 per barrel and pushed Philippine inflation to 7.2% in April 2026, with diesel logging 122.7% price inflation — the question of whether the government can act quickly without waiting for a new law becomes urgent. RA 12316 is the legislature's answer: a standing delegation of conditional power, ready to be used the next time a price crisis arrives.

The legal frame

Under the 1987 Constitution, the power to tax belongs to Congress. Article VI, Section 28(1) provides that the rule of taxation shall be uniform and equitable. However, Section 28(2) creates an important exception for trade and fiscal flexibility: Congress may authorize the President to fix tariff rates, import and export quotas, tonnage and wharfage dues, and other duties or imposts within the framework of the national development program and subject to limitations Congress imposes. This is the constitutional peg that makes RA 12316 valid — Congress is not surrendering the taxing power, it is setting the rules for a conditional, time-limited executive adjustment.

RA 12316 works by inserting a new paragraph into Section 148 of the NIRC of 1997. That section had already been amended by the TRAIN Law (RA 10963) in 2017 to introduce phased excise tax increases on petroleum products, including a built-in suspension mechanism for 2018–2020 that was tied to the same $80/barrel threshold. When that TRAIN Law clause lapsed after 2020 — having never been activated because prices stayed just below $80 during the covered period — the Philippines had no standing mechanism for executive suspension. RA 12316 fills that gap by creating a permanent (but time-limited) standby delegation. The President may issue a suspension or reduction order only when: (1) the one-month average Dubai crude oil price based on Mean of Platts Singapore (MOPS) reaches or exceeds USD $80 per barrel; (2) the Development Budget Coordination Committee (DBCC) formally recommends the suspension; and (3) the order is issued in coordination with the Secretary of Energy. All three prerequisites must be met — the President cannot act unilaterally without the DBCC recommendation and DOE coordination.

The law builds in strict temporal and quantitative limits. A single suspension order may not last more than three months. The total cumulative duration of all suspensions under the law may not exceed one year. And the entire delegated authority has a sunset clause: it expires automatically on December 31, 2028. Critically, the taxes do not require a new presidential order to revert — they automatically return to the statutory rates set in Section 148 as soon as the DOE certifies that the one-month MOPS-based average drops below $80 per barrel, or after three months, whichever comes first. The President must also submit a report to Congress within 15 days of any suspension, detailing the factual basis, policy rationale, estimated foregone revenues, and social benefits for different household income groups.

What individuals should know

If an oil price suspension is in effect, manufacturers and importers of covered petroleum products must file excise tax returns with a zero tax rate annotated with the relevant Executive Order number, and obtain the corresponding release authority from the Bureau of Customs (for imports) or file returns with the BIR (for domestic production). Consumers benefit indirectly: the savings are supposed to flow through the supply chain to retail pump prices and LPG canister prices — for EO 144, the estimated reduction was P3.37 per kilogram of LPG (roughly P37 per standard 11-kg tank) and P5.60 per liter of kerosene.

It is important to understand what the law does not do. RA 12316 does not allow the President to permanently remove or abolish petroleum excise taxes — only Congress can do that. It does not apply to all fuel products in all circumstances; the President has discretion to suspend taxes on specific products only (EO 144 deliberately excluded diesel and gasoline to avoid P43.6 billion in foregone revenues). And the authority is not open-ended: after December 31, 2028, the law expires and any future suspension would require new legislation.

For ordinary Filipinos, the practical question after any price spike is whether the $80/barrel trigger has been met and whether the President has acted. The DOE monitors MOPS-based Dubai crude prices monthly. If prices remain elevated and a suspension is issued, the BIR and BOC will publish implementing regulations that govern how the suspension is applied at the point of production or importation.
