SARS Capacity Expansion and Revenue Recovery
Theme: Revenue administration
Assessment
Responsible: South African Revenue Service / National Treasury
Feasibility Assessment
High impact, fiscally self-funding. SARS institutional recovery largely complete. AI audit capability and Large Business Centre staffing are the immediate investment priorities. Transfer pricing enforcement requires revised OECD-aligned DTAA legislation.

Description
SARS's institutional capacity was severely eroded during state capture (2014–2018), with revenue shortfalls estimated at R300+ billion over that period. The rebuilding programme under Commissioner Edward Kieswetter has restored staffing levels, re-established the High Wealth Individual unit and Large Business Centre, upgraded the SARS digital platform (eFiling, customs modernisation), and improved VAT refund processing. Revenue performance has recovered significantly, with tax-to-GDPGDP — Gross Domestic Product: The total monetary value of all goods and services produced within a country's borders in a given period. The primary measure of an economy's size and overall output. ratio rising from under 24% to approximately 25.5% by 2024/25. Further reforms include expanding the third-party data ecosystem for automatic assessments, improving customs compliance through scanner investment at ports of entry, and deepening transfer pricing enforcement. SARS's effectiveness is a foundational fiscal institution reform — each percentage point improvement in the tax-to-GDP ratio generates approximately R70 billion in additional annual revenue at current GDP levels.

SARS's R19.3 billion revenue outperformance in 2025 demonstrates that administrative reform—not new taxes—is the most powerful available fiscal instrument. Doubling the yield would close South Africa's entire deficit gap. — MTBPS 2025 Fiscal Framework
Implementation Roadmap
SARS's R19.3 billion revenue outperformance in 2025 demonstrates that institutional capacity is the single highest-leverage fiscal reform. The 2024–2028 Strategic Plan targets expanding the tax base by 1.5 million taxpayers, recovering R150 billion in outstanding tax debt, and deploying AI-powered audit tools. VAT refund backlogs (harming business cash flow) and multinational transfer pricing (R60–80 billion annual base erosion gap) are the two highest-value compliance opportunities. Every R1 invested in SARS capacity returns R6–R10 in revenue — the best return on investment in the government portfolio.
Expand third-party data integration: mandate real-time data sharing from the Deeds Office (property transactions), banking institutions (bank transaction data under Section 70 of TAA), motor vehicle registration (eNaTIS), and short-term rental platforms (Airbnb, Booking.com)
Deploy AI-powered audit selection system across all tax types: risk-score all registered taxpayers, prioritise Large Business Centre transfer pricing cases, and auto-flag VAT refund anomalies using machine learning
Staff the Large Business Centre to full complement: recruit 180 additional transfer pricing specialists and multinational risk analysts (currently 30% vacant); partner with SAICA for a professional secondment programme
International Comparisons
View all →Botswana negotiated a 50% equity stake in De Beers' diamond operations (Debswana, 1969) and channelled revenues through the Pula Fund sovereign wealth fund, achieving a fiscal savings rate above 50% of GDP in boom years. GDP per capita growth averaged 9% for 30 years (1966–1996) — the fastest sustained growth in modern history. Key institutional factors: a professional finance ministry, independent auditor general, and parliamentary review of diamond contracts. SA's management of mineral revenues and state-owned enterprise stakes could draw directly on Botswana's governance architecture.
Approach
Botswana vested mineral rights nationally rather than in tribal or district authorities, which gave one negotiating counterparty and one revenue stream, and then renegotiated the diamond agreements successively until the state held a half share of the operating company. Fiscal control was concentrated in a single ministry that owned both the budget and the project pipeline, so no department could commit spending outside the national plan. Recruitment into the senior finance and minerals cadre was competitive and technically screened, and the auditor-general and parliamentary review of the mineral contracts were kept genuinely independent.
Timeline: Diamond agreements renegotiated across 1969–1975; the planning and revenue institutions were built within the first decade after independence
Lessons for South Africa
The Botswana lesson for SARS is about where technical capacity is concentrated rather than about mining. Its revenue and negotiating expertise sat in a small, well-paid, hard-to-enter cadre insulated from political appointment — the same design as the High Wealth Individual unit and Large Business Centre that SARS has now had to rebuild twice. Transfer-pricing enforcement in particular is a thin-skills function where a handful of specialists determine the yield, which argues for protecting those units structurally rather than treating them as ordinary establishment posts. Independent audit and parliamentary review of major contracts is the other half: capacity survives only where its findings are published.
