A mine can meet its production targets and still create a material tax exposure before the financial year closes. The usual cause is not the royalty calculation alone. It is an early classification decision, an incomplete MPR3 estimate or a payment process that starts too close to the deadline.

Mining royalties South Africa are governed by the Mineral and Petroleum Resources Royalty Act 28 of 2008, commonly called the MPRRA. We support boards, investors and operating teams through mining tax and royalty advisory Africa when they need a defensible calculation, a reliable filing timetable and clear accountability between finance, technical and tax teams.

SARS administers the royalty. The charge applies when an extractor transfers a mineral resource extracted in South Africa, and it has applied since 1 March 2010. The royalty is profit-based, so a commodity does not carry one permanent fixed rate.

Start with the MPRRA royalty model

The core calculation has two parts:

1.       Calculate adjusted gross sales and EBIT for the MPR3 return.

2.       Apply the statutory formula that corresponds with the resource’s classification.

This order matters. A team that chooses a rate before establishing adjusted gross sales and qualifying deductions will often have to rebuild the return later.

SARS’s MPR3 process calculates EBIT as adjusted gross sales less the specified recoupments and deductions. The term does not simply mean the EBIT shown in management accounts. Finance teams should reconcile their accounting result to the MPRRA calculation rather than assume the two figures match.

Refined mineral resources

For refined mineral resources other than oil and gas, the royalty percentage is:

0.5% + (EBIT ÷ gross sales × 12.5)

The rate cannot fall below 0.5% or exceed 5%. Schedule 1 to the MPRRA determines whether a resource and its processing meet the refined-resource conditions. A concentrate marketed as a premium product may still fail the Schedule 1 test, because the Act focuses on prescribed processing conditions rather than commercial descriptions.

Unrefined mineral resources

For unrefined mineral resources, the royalty percentage is:

0.5% + (EBIT ÷ gross sales × 9)

The rate cannot fall below 0.5% or exceed 7%. Schedule 2 sets the relevant unrefined condition. The higher 7% ceiling reflects the statutory distinction between resources that meet the refined conditions and those that do not.

Refined oil and gas

Refined oil and gas follows a separate formula for years of assessment beginning on or after 1 January 2024:

2% + (EBIT ÷ gross sales × 12.5)

The rate is capped at 5%. The 2% minimum replaced the prior 0.5% minimum for this category, so an oil-and-gas model built on earlier assumptions needs review before the MPR3 estimate cycle begins.

Classify the mineral before you model the rate

The most expensive classification error is to treat “refined” as an operational or marketing term. Under the MPRRA, Schedule 1 and Schedule 2 decide the result. Processing records, transfer terms and product specifications therefore belong in the royalty file alongside the calculation.

We recommend that the technical lead and tax lead sign off the classification together. The tax team understands the return and the technical team understands what the plant actually produced. Neither view alone gives a board sufficient assurance.

Take an illustrative platinum producer with adjusted gross sales of R500 million and MPRRA EBIT of R100 million. If the relevant product meets Schedule 1, its EBIT-to-gross-sales ratio is 20%, producing a refined-resource rate of 3%. Its royalty would be R15 million.

If the same product does not meet the Schedule 1 conditions and falls under Schedule 2, the rate becomes 2.3%. The royalty would be R11.5 million. The point is not that unrefined always costs less in a given profit position. The point is that the formula, statutory condition and evidence must align before the business reports either number.

A second illustrative case involves a manganese operation that changes its processing route midway through the year. Assume R240 million in adjusted gross sales and R24 million in MPRRA EBIT from the relevant transfer stream, a 10% EBIT margin. Under the unrefined formula, the rate is 1.4%, producing a royalty of R3.36 million.

The finance director should not apply that rate to all sales merely because the mine uses one accounting system. They should separate the transfer streams, retain plant and product evidence, and test each resource against the relevant Schedule. If the business had designed those data fields at the start of the year, it would avoid a retrospective allocation exercise at filing time.

Register correctly with SARS

A taxpayer registers for Mineral and Petroleum Resources Royalty through the RAV01 process on SARS eFiling, or at a SARS Large Business walk-in facility. The registration uses the taxpayer’s income-tax reference number.

The older MPR1 process now forms part of RAV01. This changed the practical workflow reflected in SARS’s MPR3 completion guide, effective 17 September 2024. Do not plan for a separate legacy MPR1 submission when setting up a new royalty compliance process.

Before registration, confirm that the entity has an active registered representative and that its eFiling payment functionality works. SARS does not treat payment as a standalone step outside the MPR3 process. A technically correct calculation will not cure an account that cannot submit or pay on time.

For a new South African entrant, company registration, tax registration and mining tax compliance should be sequenced as one controlled workstream. Leaving the royalty registration to the first transfer date creates unnecessary execution risk.

File the MPR3 in four stages

SARS requires more than one annual filing event. Taxpayers submit the MPR3 through eFiling and make payments against estimates during the year of assessment.

1. Submit the first estimate

File the first estimate and pay 50% of the estimated royalty by six months after the start of the year of assessment. This deadline forces management to establish a view of production, sales, deductions and classification well before year-end.

For a year starting on 1 January, the first estimate and 50% payment fall due by 30 June. Finance teams should work backwards from that date, not wait for the final production figures.

2. Submit the second estimate and balance

File the second estimate and pay the balance by the end of the year of assessment. The second estimate should incorporate actual volumes, realised transfer values and updated deductions, not simply roll forward the first estimate.

3. Consider a top-up payment

A taxpayer may make an optional top-up payment within six months after year-end. This window gives management an opportunity to reduce the gap between provisional payments and the final royalty once better information becomes available.

4. Reconcile and settle the annual position

Submit the annual reconciliation and make any final settlement within 12 months after year-end. The annual process is where SARS can see whether the estimates, payments and final calculation tell one coherent story.

One operating mistake appears repeatedly in planning meetings: management budgets for an annual MPR3 only. The MPRRA compliance calendar includes two estimates, associated payments, a possible top-up and a final reconciliation. Put all four events into the tax calendar and assign an owner for each.

Manage the small-business exemption and penalties

The small-business exemption does not apply if total adjusted gross sales exceed R10 million or the net royalty exceeds R100,000 for the year. Both measures matter because the exemption falls away when either statutory limit is crossed.

If your mine expects adjusted gross sales close to R10 million, do not base cash-flow planning on the exemption without a documented forecast and a check of the net royalty. A modest change in sales or margin can move the business outside the exemption.

SARS may impose a penalty of up to 20% of the excess if the final royalty, less the first and second estimate payments, exceeds 20% of the final royalty. The penalty is due within 30 days, and late royalty payments attract monthly interest.

This is why an intentionally low estimate is poor treasury management. It may preserve cash for a short period but can create a penalty exposure if the final result differs materially from the two estimate payments.

Build a board-ready royalty control file

A sound royalty file should show the full path from mineral transfer to payment. We normally expect it to include the Schedule 1 or Schedule 2 classification assessment, adjusted gross sales support, MPRRA EBIT reconciliations, estimate assumptions, MPR3 submission evidence and payment confirmations.

The file also needs dates. SARS’s current MPR3 completion guide took effect on 17 September 2024, while the refined oil-and-gas formula changed for years beginning on or after 1 January 2024. A control file that records the applicable law and guidance avoids applying an outdated assumption to a current assessment year.

These calculations affect tax, valuation and transaction diligence. Mining tax and royalty advisory should therefore sit alongside financial due diligence and governance reporting, rather than operate as an isolated annual return exercise.

Frequently Asked Questions

Is South Africa’s mining royalty a fixed percentage?

No. The MPRRA royalty depends on adjusted gross sales, MPRRA EBIT and the statutory refined or unrefined classification. Refined resources other than oil and gas have a 0.5% to 5% range, while unrefined resources have a 0.5% to 7% range.

Who collects mining royalties in South Africa?

SARS administers and collects Mineral and Petroleum Resources Royalty under the MPRRA. Taxpayers register through RAV01 on SARS eFiling or at a SARS Large Business walk-in facility.

When is the first MPR3 estimate due?

The first MPR3 estimate and 50% payment are due six months after the beginning of the year of assessment. A taxpayer with a 1 January year-start would plan for a 30 June due date.

Does refined oil and gas use the ordinary refined-mineral formula?

No. For years of assessment beginning on or after 1 January 2024, refined oil and gas uses a 2% minimum plus the profitability component, capped at 5%. The separate minimum is a recent change that requires specific review.
