SARS diesel rebate requirements
South African farming and agriculture diesel rebate claims need more than fuel invoices. A farmer must be able to show which diesel was bought, where it was stored, which vehicle, machine, pump, generator, or implement used it, what work was done, and whether those litres were used for qualifying farming activities.
Agri-Fleet Systems helps farms build the operational record behind a claim by connecting fuel, vehicles, machine activity, locations, and exceptions into one audit-ready trail. This page is general information, not tax advice. Always confirm final treatment with SARS or your tax adviser.
AgriFS can capture purchased fuel records, but the supporting tax invoices and delivery or collection documents are still required for the audit trail.
SARS says diesel refund claimants must keep records showing diesel purchases, storage, and usage, including the vehicles filled and the qualifying activity conducted. For agriculture, that means the diesel rebate logbook should connect each claimed litre to real farming work, not only to a supplier invoice.
The practical chain is invoice to tank, tank to machine, machine to field or activity, and activity to qualifying or non-qualifying use. Private use, road transport, labour transport, and mixed-use activity should be separated so the claim can be checked against the underlying records.
The key question is not only whether diesel was bought. It is whether the claimed litres can be traced from purchase to storage, from storage to machine, and from machine to a qualifying agricultural activity.
A practical SARS diesel rebate logbook should show diesel purchased, stored, issued, and used. For each usage entry, capture the machine or vehicle, date, litres, meter or hour readings, location, operator, and the specific farming activity performed. The record should also separate qualifying agricultural use from private, transport, road, or other non-qualifying use.
No. Purchase invoices are important, but they do not prove that the diesel was used for qualifying farming activities. The claim should be supported by usage records that trace litres from invoice to storage to the machine or activity where the diesel was consumed.
SARS guidance says relevant diesel purchase documentation and logbook or other records showing eligible and non-eligible use must be retained for five years from the date of use or disposal of the fuel or the refund return, whichever occurs last.
If a claimant cannot substantiate eligible diesel usage, SARS may disallow the refund. That can lead to repayment of the refund and possible penalties or interest. The safest approach is to maintain detailed records before an audit or verification request arrives.
Do not assume that it qualifies. Public-road transport, private use, labour transport, and mixed-use trips are common audit risk areas. Record them separately and confirm whether the specific activity qualifies under the current SARS diesel refund rules before claiming those litres. AgriFS can take most of this workload off your hands by using point of interest systems to automatically identify farms, fields, roads, depots, and other operating locations, helping automate roughly 90% of the usage classification work while still keeping the audit trail reviewable.
Yes, when it supports the audit trail. GPS, fuel issues, engine hours, and machine activity can help show where and how diesel was used. The important point is that the technology must produce records that map back to purchase, storage, usage, and qualifying activity evidence.
SARS has announced a modernised Diesel Refund System, including a standalone platform for diesel refund registration and claims that is being piloted and tested before launch. AgriFS is part of a broader working group with SARS, Grain SA, farmers, and other technology providers, which helps us keep the system aligned with the direction of future diesel refund requirements as they become clearer. For farmers, the practical lesson is that rebates are inevitably moving toward cleaner digital records, structured exports, and audit-ready evidence that can adapt as SARS guidance changes.
Under the old onland system, qualifying farming, forestry, and mining users calculated eligible diesel and then only 80% of those eligible litres were claimable. SARS has announced that, from 1 April 2026, qualifying onland users can claim a refund on 100% of eligible diesel used in qualifying activities, with the transition reflected from the May 2026 VAT return cycle. This is unlikely to simply mean more free money. It will probably result in higher scrutiny of what is considered eligible, so detailed records become more important, not less. Farms still need records that clearly separate qualifying activity from non-qualifying, private, transport, road, or mixed use.
Audit reinterpretation support
SARS interpretation of the diesel refund rules can differ from how a farmer or accounting team interpreted the same activity when the claim was prepared. That does not always mean the whole diesel rebate record has to be written off.
Because AgriFS keeps the raw trip, location, fuel, and machine activity data as it was captured, trips can be reprocessed later with new interpretation rules that come out of an audit or SARS review. If an activity needs to be treated differently, AgriFS can reinterpret the relevant trips under that alternative SARS view and provide recalculated results for SARS to review as part of the audit process.
SARS rules, rates, forms, and registration flows can change. Use the current SARS diesel refund guidance as the source of truth before publishing compliance-specific claims or submitting a refund.
