The Mining
Sector Tax
Minefield

For two decades, transfer pricing compliance in African mining was more art than science. Revenue authorities lacked the technical expertise, data access, and legal frameworks to challenge even obviously aggressive pricing. That era is ending — rapidly and simultaneously across multiple jurisdictions.

The African Tax Administration Forum (ATAF), in partnership with the OECD, IMF, and Intergovernmental Forum on Mining (IGF), has spent five years building the technical capacity of African revenue authorities specifically to audit extractives sector transfer pricing. Zambia, Ghana, Tanzania, and Kenya now have dedicated transfer pricing units staffed by specialists trained in commodity valuation methodologies.

The result is a fundamentally different risk environment. Companies that structured their inter-company pricing arrangements for a world where detection was unlikely are now facing the consequences of those choices.

Zambia is the clearest example of what happens when a revenue authority develops genuine transfer pricing capacity in the extractives sector. The Zambia Revenue Authority (ZRA), working with ATAF and the IGF, has conducted transfer pricing audits of copper mining companies that revealed, in the words of the IGF's own assessment, "potentially millions of dollars in mining taxes at risk."

The reforms that followed were specific and technical: Zambia introduced mining-specific transfer pricing rules requiring export price benchmarking against international commodity indices such as the London Metal Exchange copper price. Inter-company sales at prices diverging significantly from LME benchmarks are now automatically flagged for audit.

Ghana Revenue Authority has strengthened its Transfer Pricing Unit with a specific mandate to audit high-risk extractive industries — gold, manganese, and bauxite. The Ghana Extractive Industries Transparency Initiative (GHEITI) has already published findings of export value discrepancies indicating systematic under-invoicing, providing the evidentiary foundation for targeted audits.

The 2025 Tax Amendment Act further increased the gold "growth and sustainability levy" from 1% to 3%, adding a new cost layer on top of the existing transfer pricing exposure. For gold mining companies, the combination of the higher levy and heightened TP audit scrutiny represents a materially different cost structure than was modelled even 18 months ago.

The Democratic Republic of Congo presents the most complex transfer pricing environment on the continent. The OECD has found that illegal mineral exports through informal routes make up more than 20% of total production in some DRC regions — a figure that makes formal sector transfer pricing enforcement simultaneously more difficult and more urgent.

For legitimate mining operators in the DRC, the enforcement dynamic is paradoxical. The presence of large informal sector flows means that formal sector pricing is subject to intense scrutiny as authorities try to verify that what is declared reflects actual transactions. Transparency — through robust transaction documentation, third-party commodity price benchmarking, and consistent reporting — is the only defensible posture.

Across all five jurisdictions, three transfer pricing issues dominate audit triggers in the mining sector. Understanding these is the starting point for any defensible compliance strategy.

Commodity export pricing. This is the most common and most significant issue. When a mining company sells minerals to a related party (typically a trading entity in Switzerland, Singapore, or the UAE) at a price below the prevailing spot or benchmark price, revenue authorities treat the difference as a taxable benefit shifted offshore. The benchmark methodologies — LME for copper and cobalt, LBMA for gold — are now explicitly written into Zambia's transfer pricing rules and referenced in ATAF guidance across the continent.

Management fees and service charges. Intra-group charges for services — management consulting, headquarters costs, brand royalties, technical assistance — are systematically scrutinised. Revenue authorities apply a two-part test: are the services genuinely provided, and is the price arm's length? Many historic management fee arrangements fail both tests.

Related-party financing. Thin capitalisation and high-interest intercompany loans are a persistent issue. As African tax authorities adopt OECD BEPS-aligned interest limitation rules, the deductibility of these charges is increasingly challenged.

The businesses that navigate mining sector transfer pricing audits successfully share a common characteristic: their documentation existed before the audit began. Transfer pricing documentation is not something that can be reconstructed after an audit notice arrives. Revenue authorities treat the existence of contemporaneous documentation as evidence of good faith; its absence as evidence of avoidance.

A defensible transfer pricing position for an African mining operation requires, at minimum: a formal transfer pricing policy covering all material inter-company transactions; a benchmarking study for commodity sales referencing published market prices; functional analyses for management fee arrangements documenting what services are actually provided and how they are priced; and loan documentation that reflects market terms. These are not exotic requirements — they are the minimum standard that ATAF guidance and OECD BEPS implementation have established as baseline expectations.
