South Africa’s diesel refund regime has been operating under reform pressure for over a decade, and the first tangible change finally arrived in April 2026: on-land diesel users may now claim a full refund of the general fuel levy and Road Accident Fund levy on qualifying off-road production activities, replacing a longstanding 80% cap that the National Treasury had acknowledged was never part of the original policy design.
The fuel levy and Road Accident Fund levy together added roughly R7.82 per litre to the pump price of diesel as of the 2025/26 budget. For large consumers — commercial farmers, mining houses, fishing fleets, and forestry operators — the annual rebate exposure runs into hundreds of millions of rands. The shift from 80% to 100% recoverability is commercially material, though practitioners caution that the more fundamental reform remains stalled.
That reform — a complete restructuring of the rebate system under an amended Customs and Excise Act approved in 2022 — was supposed to separate the refund mechanism from the value-added tax system and introduce a standalone digital registration and claims platform administered directly by the South African Revenue Service (SARS). The new system was due to open for registrations in April 2026. SARS communicated to stakeholders in March that it required additional time to pilot and test the platform before going live, with no revised public deadline issued.

Indirect tax specialists are sceptical about the timeline. Christo Theron of TradeTaxPlus, who has followed the reform process since its inception, noted that the new system requires users to register their entire value chain — the user, the supplier, the distributor, and all eligible assets — on a single SARS profile. That is a substantially more complex administrative exercise than the current system, and Theron assessed a year-end 2026 go-live as optimistic.
The stakes for non-compliance are significant. The Customs and Excise Act carries substantial penalty provisions for incorrect claims. A Supreme Court of Appeal judgment involving mining company Assmang resulted in the company being ordered to repay nearly R40 million in diesel refunds plus interest, primarily because its record-keeping failed to meet the prescribed standards — not because the diesel was used for ineligible purposes. The case illustrated how procedural requirements can override the economic substance of a claim.
Under the amended legislation, monthly logbooks will replace the current daily records requirement — a concession to operational practicality. SARS will provide standardised minimum usage logbooks, though users may submit simplified alternatives provided they capture the prescribed data. Mixed-use environments, where diesel powers both eligible production activities and non-eligible support functions, remain an area of particular audit risk, requiring rigorous apportionment on a consistent and documented basis.
The broader context is one of elevated diesel costs. The international oil price environment has remained volatile, and South Africa’s diesel pump price — influenced by the rand exchange rate, the Brent crude benchmark, and the levy structure — has placed sustained pressure on energy-intensive sectors. The government’s decision not to extend the temporary fuel levy relief measures introduced during 2022 and 2023, as confirmed in the 2025/26 budget, means that the rebate regime carries more commercial weight than at any prior point. Getting the reform right — and getting it live — matters increasingly to the sectors that depend on it.
