Corporate Tax in South Africa: What Foreign Companies Pay [2026]

The 2026 headline rates — at a glance

South African corporate tax is administered by SARS (the South African Revenue Service) under the Income Tax Act 58 of 1962. For a foreign group weighing up market entry, these are the numbers that matter. Figures last reviewed 16 July 2026.

The Budget tabled on 25 February 2026 changed none of these. It also withdrew the R20 billion in tax increases that had been provisionally pencilled in during 2025 — so the 2026 corporate tax landscape is stable, not tightening. SARS put it plainly:

Value-added tax sits at 15% — covered separately in VAT for foreign companies, whose registration rules can reach a foreign supplier with no South African presence at all.

Subsidiary vs branch: how each is taxed

A foreign investor operates in South Africa through one of two vehicles: a locally incorporated subsidiary (a private company, “(Pty) Ltd”) or a branch — the foreign company itself, registered with CIPC (the Companies and Intellectual Property Commission) as an external company. The tax arithmetic differs at the point profits leave the country:

• Subsidiary: pays 27% CIT on worldwide income, then 20% dividends tax when it distributes the after-tax balance to its foreign parent. Fully distributed, that is a combined 41.6% before treaty relief — with a typical 5% treaty rate it drops to a little over 30%.
• Branch: pays the same 27% on profits attributable to the South African operations, and remits the balance to head office with no further tax. The old branch-rate premium (33%, later 28%) is long gone, and dividends tax does not apply to branch remittances.

On pure rate arithmetic the branch often wins. In practice most foreign groups still choose the subsidiary for non-tax reasons — limited liability, commercial optics, banking, and scoring under B-BBEE (Broad-Based Black Economic Empowerment). The full decision framework, including audit and exit costs, is in subsidiary or branch?

Getting money out: dividends, interest, royalties — and treaty relief

Dividends tax: 20%, reduced by treaty — if you file first

Dividends paid by a South African resident company to foreign shareholders attract dividends tax, withheld at source:

Here is the trap international groups fall into: treaty relief is not automatic. Under section 64G(3) of the Income Tax Act, the foreign beneficial owner must lodge the prescribed declaration and undertaking with the withholding agent before the dividend is paid. Miss that sequencing and the company must withhold the full 20%, leaving the shareholder to claim a refund from SARS — slow, paper-heavy, and entirely avoidable. Typical treaty rates for corporate shareholders:

One warning about older advice: for a decade, Dutch and Swedish holding companies could reach 0% dividends tax through a most-favoured-nation (MFN) chain that borrowed the old SA–Kuwait treaty’s exclusive-residence dividend article. That route is dead: the protocol to the SA–Kuwait treaty entered into force on 2 October 2024 (Government Gazette 51637 of 22 November 2024), replacing 0% with 5%/10% and collapsing the MFN chain. Whether historic pre-protocol claims survive is contested — take advice before relying on any pre-2024 position.

Interest: 15%, with broad exemptions

The exemptions in section 50D are wide enough that much cross-border interest escapes the net entirely: interest paid by the South African government or by banks, interest on listed debt, interest paid by headquarter companies on qualifying back-to-back funding, and interest on debt owed by one foreign person to another (within limits) are all exempt — the full list is in SARS Interpretation Note 115. On top of that, several major treaties (including the UK, Netherlands, US and Sweden) reduce interest withholding to 0%; Germany’s 1973 treaty allows 10%.

Royalties: 15% — and no tax on service fees

Royalties paid to non-residents attract a final 15% withholding (rate in force for royalties paid on or after 1 January 2015), routinely reduced — often to 0% — by treaty. Management and technical service fees carry no withholding tax at all: the proposed service-fee withholding was repealed with effect from 1 January 2017 without ever coming into force. Instead, cross-border service arrangements above R10 million where the non-resident’s people are physically present in South Africa must be disclosed to SARS as reportable arrangements — and, as the next section shows, that physical presence carries its own, bigger risk.

Every one of these outbound payments also crosses South Africa’s exchange-control perimeter — see exchange control for foreign investors for the authorised-dealer formalities that run alongside the tax rules.

Permanent establishment: when trading with South Africa becomes taxable in South Africa

A foreign company that merely sells into South Africa — exports, cross-border licensing, remote services — is taxable here only on income from a South African source. Where a double taxation agreement (DTA) applies, the shield is stronger still: business profits may be taxed in South Africa only if the company has a permanent establishment (PE) here, and then only the profits attributable to that PE. Registering as an external company with CIPC is a company-law obligation triggered by “conducting business” — it does not itself create a PE, and the two tests are applied independently.

The classic PE triggers are a fixed place of business (an office, workshop or site), a dependent agent who habitually concludes contracts here — and, less intuitively, people. South Africa’s Tax Court has held that consultants working for months from a client’s boardroom created a services PE:

Treaties cut both ways, though — where a DTA allocates taxing rights away from South Africa, it prevails over domestic charging provisions:

A modern overlay: the OECD’s Multilateral Instrument (MLI) has applied to South Africa’s covered treaties since 1 January 2023, adding a principal-purpose test and tighter agency-PE rules (South Africa listed 76 treaties; per SARS, 50 partners have ratified). The US and German treaties are not covered, so those older texts apply unmodified — check the OECD matching database for your treaty before structuring.

Buying South African property — or land-rich shares

Two special rules catch real-estate-heavy deals. First, when anyone buys South African immovable property for more than R2 million from a non-resident seller, section 35A of the Income Tax Act makes the purchaser withhold 7.5% (natural persons) / 10% (companies) / 15% (trusts) of the price as an advance on the seller’s capital gains tax. In SARS’s words:

Second, the land-rich share rule (paragraph 2(2) of the Eighth Schedule) pulls a non-resident’s share disposal into South African capital gains tax where 80% or more of the shares’ market value derives, directly or indirectly, from South African immovable property and the seller (with connected persons) holds at least 20% of the equity — SARS’s Tax Guide for Share Owners sets out the test. Companies pay CGT at an effective 21.6%. Long-term occupation structures have their own registration layer — see notarial long-term leases.

Funding the South African company: three constraints in one loan

Most foreign parents fund their South African subsidiary with a mix of equity and shareholder loans. Three regimes hit the loan simultaneously — price the funding around all of them before signing:

• Transfer pricing (section 31). Cross-border connected-party terms must be arm’s length — both the interest rate and the quantum of debt. Any excess benefit is added back to taxable income, and the secondary adjustment treats the excess as a deemed dividend in specie taxed at 20% — with no treaty relief, on SARS’s view in Interpretation Note 127, because a deemed dividend has no beneficial owner. Documentation: a master file and local file become mandatory once aggregate cross-border connected-party transactions exceed R100 million for the year; country-by-country reporting starts at R10 billion consolidated group revenue.
• Interest-deduction cap (section 23M). Interest owed to a non-resident connected/controlling creditor that is not subject to South African tax on it is deductible only up to 30% of adjusted taxable income (years of assessment ending on or after 31 March 2023); the excess carries forward.
• Interest withholding. The 15% withholding tax applies to the interest actually paid, subject to the exemptions and treaty reductions above.

A fourth constraint operates at the level of losses: a company’s brought-forward assessed loss can shelter only the higher of R1 million or 80% of taxable income in any year — the balance carries forward, and once taxable income exceeds the R1 million floor, the unsheltered slice is taxed even while losses remain. Advance pricing agreements are not yet practically available — SARS’s bilateral-only pilot is still at draft stage (April 2026) and restricted to very large taxpayers. A dedicated transfer-pricing deep-dive is coming to this hub.

The sweeteners: SEZs, headquarter companies, R&D and the ETI

Four regimes can materially cut the effective rate for the right business model:

• Special Economic Zones (SEZs) — 15% CIT. Qualifying companies in the six zones approved by the Minister of Finance (Coega, Dube TradePort, East London, Maluti-a-Phofung, Richards Bay and Saldanha Bay — see InvestSA) pay 15% instead of 27%, plus an accelerated building allowance. The incentive sunsets for years of assessment commencing on or after 1 January 2031.
• Headquarter companies (section 9I). An elective regime for using South Africa as a holding platform for African operations: no dividends tax on the headquarter company’s own distributions, withholding-tax relief and transfer-pricing carve-outs on back-to-back funding — but strict 10%-per-shareholder, 80%-asset and 50%-income tests.
• R&D super-deduction (section 11D). A 150% deduction for approved scientific and technological R&D performed in South Africa, extended to 31 December 2033 — pre-approval by the Department of Science, Technology and Innovation is required (SARS R&D incentive page).
• Employment Tax Incentive (ETI). A monthly credit against payroll tax for young, lower-paid hires — per SARS’s published values from 1 April 2025, up to R1,500 per month in the first twelve months and R750 in the second twelve, for employees earning under R7,500 per month, with the incentive running to 28 February 2029. SARS notes the 1 April 2025 values apply for twelve months pending Parliament passing the enabling legislation — check the current values before modelling. Hiring rules more broadly are covered in employment law essentials.

The SEZ rules are also being reworked. The 2026 Budget Review proposes replacing the rigid connected-party disqualification with an arm’s-length pricing test — a proposal, not yet law:

The 15% global minimum tax is live in South Africa

South Africa has implemented the OECD’s Pillar Two. The Global Minimum Tax Act 46 of 2024 (with its companion Administration Act 47 of 2024) imposes an income inclusion rule (IIR) and a domestic minimum top-up tax at a 15% effective-rate floor on multinational groups with consolidated revenue of EUR 750 million or more in at least two of the preceding tax years. The Acts were signed in December 2024 and January 2025 but apply retroactively to fiscal years beginning on or after 1 January 2024. South Africa has not enacted the under-taxed profits rule (UTPR).

Two practical consequences for inbound groups above the threshold. First, incentive-driven low effective rates — the 15% SEZ rate, heavy R&D deductions — can be clawed back to 15% by the domestic top-up, so model incentives net of Pillar Two. Second, the rules are still moving: the 2026 Budget confirms the updated OECD rules arrive in 2026/27.

The compliance calendar

Every South African company — including a registered external company — is a provisional taxpayer. The annual cycle, all run through SARS eFiling, looks like this:

1. Registration is automatic: CIPC feeds new companies (and external companies) straight to SARS, which issues an income tax number via the CIPC–SARS interface. You must, however, appoint a public officer — a senior official resident in South Africa (section 246 of the Tax Administration Act 28 of 2011) — see resident directors and the public officer.
2. Provisional tax (IRP6): a first estimate and payment six months into the year of assessment, a second by year-end, and an optional third top-up about six months later to stop interest running.
3. Annual return (ITR14): due within 12 months of financial year-end, with financial statements attached. Late filing triggers recurring monthly administrative penalties that scale with taxable income.
4. Event-driven filings: dividends-tax returns when you distribute, and transfer-pricing master/local files within 12 months of year-end once past the R100 million threshold.

The wider registration stack — PAYE, UIF, SDL, VAT and customs, each with its own deadline — is mapped in tax and employer registrations after incorporation. And plan around the real bottleneck: tax numbers are near-instant, but opening the bank account (with verification of foreign beneficial owners under FICA, the Financial Intelligence Centre Act) is routinely the long pole in go-live.
