Chile’s Private Miners to Pay Record US$8 Billion in 2026

Chile · Mining

*A windfall from soaring copper revenues is set to test Chile’s ability to turn subsoil wealth into lasting public goods, as a landmark tax overhaul delivers its first full-year results.*

Where the record sum originates

Chile’s Ministry of Finance projects fiscal revenues from large-scale private mining will reach CLP 6,999,144 million in 2026, an 11.5% increase from the previous estimate. At the official exchange rate, this translates to roughly US$8.0 billion, marking the largest single-year tax and royalty take from private miners on record.

The figure covers income tax, the new mining royalty, and related charges paid exclusively by private firms, excluding state-owned giant Codelco. It reflects a sharp upward revision driven by favorable copper prices and robust export volumes.

How the new royalty regime works

Since 2024, large copper producers with annual sales above 50,000 metric tons and deriving more than half their revenue from copper must pay a 1% ad valorem tax on annual copper sales. On top of that, they face a margin-based royalty of 8% to 26% on Adjusted Taxable Mining Operating Income, known by its Spanish acronym RIOMA.

The rate escalates as operating margins rise, ensuring the state captures more revenue during boom cycles. To protect investment viability, a statutory cap limits the combined burden of corporate income tax, withholding tax, and the mining royalty to 46.5% of operating profit for producers exceeding 80,000 tonnes of fine copper per year, and 45.5% for those between 50,000 and 80,000 tonnes.

Copper’s dominant role in state revenue

The new royalty alone is expected to generate around US$1.35 billion annually from 2025 onward, equivalent to about 0.45% of Chile’s GDP. Broader government revenue from mining, excluding oil and gas, was estimated at roughly US$5 billion in 2024, with copper accounting for 43% of that total.

For 2026, official projections show total real government revenues rising to about 21.7% of GDP, with mining-related income revised up primarily because of higher copper prices and production. The private sector’s US$8.0 billion contribution thus represents a substantial slice of the fiscal pie.

Where the royalty money is spent

Of the US$1.35 billion per year expected from the Mining Royalty Law, US$450 million is legally earmarked for regional and municipal development. This allocation channels copper wealth directly to communities, especially those most affected by extraction.

The Regional Fund for Productivity and Development receives roughly US$225 million annually for regional governments. A Territorial Equity Fund gets about US$170 million for lower-income municipalities, while a Mining Municipalities Compensation Fund directs US$55 million to communes that host mining operations.

What the record haul means for investors

The 2026 forecast signals that Chile’s tax framework is now highly responsive to copper price cycles, locking in higher state take when margins expand. For international investors, the 46.5% total burden cap provides a clear ceiling on fiscal exposure.

The earmarking of one-third of new royalty revenue for territorial equity also aims to ease social tensions in mining regions, a persistent risk for project permitting. Whether the windfall translates into streamlined approvals and infrastructure remains an open question for the industry.

Frequently Asked Questions

Who pays the new mining royalty?
Large private copper producers with annual sales above 50,000 metric tons and more than 50% of revenue from copper. State-owned Codelco is not included in the private-sector figures.

How is the royalty calculated?
It combines a 1% ad valorem tax on annual copper sales with a margin-based royalty of 8% to 26% on Adjusted Taxable Mining Operating Income, depending on the operating margin.

Is there a limit on how much miners can be taxed?
Yes. The combined burden of corporate income tax, withholding tax, and the mining royalty is capped at 46.5% of operating profit for the largest producers and 45.5% for mid-tier operators.

How much of the royalty goes to local communities?
About US$450 million per year is earmarked for regional and municipal funds, including direct compensation for mining-affected communes and support for lower-income municipalities.
