DOF rolls out IRR for new mining tax lawThe Department of Finance expects to generate P6.3 billion a year in additional revenue from the implementation of the new mining tax law. MANILA, Philippines — The Department of Finance (DOF) has issued the implementing rules and regulations (IRR) for Republic Act 12253, also known as the Enhanced Fiscal Regime for Large-Scale Metallic Mining Act, which outlines the updated tax, royalty and revenue-sharing provisions of the law. The rules impose ring-fencing, preventing large-scale metallic mining operators from consolidating income and costs across projects or offsetting losses against profits when computing royalties and windfall profit taxes. Metallic mining activities conducted in mineral reservations will be liable for a royalty equivalent to five percent of the total output of extracted or produced minerals or mineral products. For those outside mineral reservations, a margin-based royalty on income from metallic mining operations exceeding 60 percent will be subject to a five percent rate.
