For mining activities, a specific royalty regime applies, with effective rates ranging from 1% to 4% on gross sales, depending on production levels.

Damalion facilitates the entire structuring process, from selecting the optimal tax regime for your entity to managing registrations with local authorities and securing eligibility for available incentives.
Double Tax Treaties: Reducing Withholding and Cross-Border Friction
As of March 2026, the country has over 30 active double taxation treaties, including recent updates that specifically benefit investors from Brazil, Canada, Spain, and China. Notably, the new protocol with Brazil has reduced withholding tax on dividends paid to Brazilian corporate shareholders to 10%, with interest payments now capped at 15%. This development directly enhances after-tax returns for cross-border investors and simplifies compliance burdens. The treaty network also provides exemptions or reductions for royalties and technical service fees, depending on the counterparty’s jurisdiction.
- Dividends: Treaty rates between 5% and 15%, depending on shareholding structure
- Interest: Typically reduced from 35% to 15% or less
- Royalties: Often limited to 10% or 15%
- Permanent establishment rules provide clarity on what triggers local taxation
Damalion’s local network enables investors to efficiently document treaty eligibility, prepare the necessary residency certificates, and maintain compliance with evolving cross-border tax rules.
Transfer Pricing and Compliance: What’s New in 2026?
For multinationals operating in Antofagasta, transfer pricing compliance remains a top priority, especially given heightened scrutiny on intra-group transactions in the mining and energy sectors. The country requires contemporaneous transfer pricing documentation for all related-party transactions exceeding 500 million CLP annually (approximately $560,000). Failure to comply can trigger penalties of up to 30% of the transfer pricing adjustment amount, plus interest. The 2026 regulatory update now mandates country-by-country reporting for groups with global revenues above 750 million euros, aligning local rules with international standards.
Investors should prioritize robust benchmarking studies and periodic reviews of their intercompany agreements, particularly for financing, management services, and sales of extracted resources. Early alignment with the latest requirements ensures smooth audits and reduces the risk of costly disputes.
