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-GDP 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.

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.

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.

2024–2028 Strategic Plan horizon; quick wins (VAT refund reform, LBC staffing) within 12 months; full tax base expansion and BEPS Pillar Two enforcement by 2028

Estimated Cost

SARS operating budget R7.2 billion (2025/26); additional revenue recovery investment R1.2 billion/year; OECD benchmark: each R1 invested in tax administration returns R6–R10 in additional revenue. MTBPS 2025 cites SARS capacity as the primary fiscal stabilisation mechanism in the absence of new tax rate increases.

Required Legislation

Tax Administration Act 28 of 2011 (Section 70 third-party data mandate — regulations update needed for digital platform operators); Income Tax Act amendment for BEPS Pillar Two (15% global minimum tax); Taxation Laws Amendment Act 2025 (annual omnibus bill process). No new primary legislation required for AI audit tools, LBC staffing, or VAT refund process redesign.

Political Feasibility

SARS institutional recovery has rare genuine multiparty consensus — the Moyane-era collapse was politically damaging across all parties, and the Kieswetter-era recovery is publicly credited across the political spectrum. The PC on Finance BRRRs show strong parliamentary enthusiasm for SARS capacity investment. Resistance comes from the business community on VAT over-verification risks and from multinational corporations on Pillar Two compliance costs — neither has blocking power in the current GNU configuration.

International Precedents

Rwanda Revenue Authority: 60% revenue increase over 5 years through IT investment and third-party data integration, growing the tax-to-GDP ratio from 10% to 17%. Kenya's iTax system (2013) automated returns and cut compliance time 70% while expanding the tax base by 2 million taxpayers in 3 years. Georgia (2004–2012) achieved the fastest improvement in the IMF Tax Administration Diagnostic Assessment Tool (TADAT) history through radical institutional reform directly analogous to SARS's post-Moyane recovery.

International Comparisons

🇧🇼Botswana1969

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.

🇬🇪Georgia2004

Georgia cut petty corruption dramatically after 2004: the entire traffic police (16,000 officers) was dismissed and replaced with a smaller, better-paid force. Public service salaries were raised to market rates, funded by tax administration reform that doubled the tax-to-GDP ratio. Transparency International CPI improved from 2.0 (2003) to 5.2 (2014). Doing Business rank improved from 112th (2006) to 15th (2014). The approach required political will to absorb short-term disruption but demonstrated that rapid institutional change is possible. SA's NPA and SAPS face analogous institutional capture challenges.

Approach

Georgia paired dismissal with rebuilding. Units judged unsalvageable — most visibly the traffic police — were abolished outright and re-staffed on open competition at market salaries, funded from the revenue gains. The tax code was rewritten to cut the number of separate taxes sharply and to remove the discretionary exemptions that gave officials something to sell. Tax and customs administration were merged into a single revenue service with electronic filing and payment, so routine compliance no longer required a face-to-face encounter, and enforcement effort was concentrated on large taxpayers.

Timeline: Personnel and tax-code changes inside 2004–2005; revenue and perception gains visible within 3–5 years

Lessons for South Africa

SARS's rebuild has run the constructive half of Georgia's programme — restaffing, the High Wealth Individual unit and Large Business Centre, eFiling and customs modernisation — without the destructive half, which is a defensible choice in a constitutional labour-law setting. What travels is the design principle behind the Georgian code rewrite: every discretionary exemption and every manual assessment is an opportunity to sell a decision. SARS's expansion of third-party data and auto-assessment removes those contact points at scale, and is worth more to revenue integrity than additional enforcement headcount.
