UK Taxes for Expats Living in South Africa
South Africa is home to a significant British expatriate community, concentrated in Cape Town, Johannesburg, and the Garden Route. The UK-South Africa Double Taxation Agreement protects against most double taxation, but UK nationals in South Africa must navigate HMRC's Statutory Residence Test, ongoing UK obligations on UK-source income, and South Africa's own exchange control regulations. The interaction between UK domicile (for UK inheritance tax) and South African financial regulations adds further complexity for long-term British residents.
Local tax authority
The UK-South Africa Double Taxation Convention (2002) covers income tax and capital gains. Government pensions are taxable only in the UK. Employment income is taxable in the country of performance. Dividends attract 5% withholding (substantial holdings) or 15% (portfolio). Interest is taxable at 0% at source under the treaty. Royalties attract 0% at source. The treaty uses primarily the credit method to prevent double taxation.
South Africa-specific complexities for UK filers
- South Africa taxes residents on worldwide income; UK nationals who become South African residents must declare worldwide income to SARS
- South Africa's exchange control regulations limit how much money can be transferred out of South Africa (annual allowances apply)
- South African National Treasury implemented the 'South African expat tax' from 1 March 2020, taxing South African tax residents on foreign employment income above ZAR 1.25m
- UK nationals in South Africa may face UK inheritance tax (if UK-domiciled) and South African estate duty simultaneously
- SARS requires individuals who cease South African tax residency to pay an 'exit tax' on deemed disposal of worldwide assets
- South African CGT rates (40% inclusion rate for individuals) are creditable against UK CGT on the same asset
What's different about filing from South Africa
Establishing UK non-residence when moving to South Africa
The Statutory Residence Test determines when you cease UK tax residency. For the year of departure to South Africa, Split Year Treatment divides your UK-taxable income between the UK-resident period (fully taxable) and the non-resident period (only UK-source income taxable). Getting this right in the departure year Self Assessment is essential — it establishes the baseline for all subsequent years and protects against HMRC treating you as a continuing UK resident.
UK property and the Rand: exchange control considerations
Many UK nationals in South Africa maintain UK property. UK rental income remains taxable in the UK under the DTA. However, transferring rental income or UK property sale proceeds into South Africa may trigger South African exchange control rules and SARS reporting obligations. The interaction between UK Non-Resident Landlord obligations (HMRC) and South Africa's foreign investment rules requires coordinated planning, particularly for larger properties or multiple UK assets.
UK domicile and South African estate duty
UK nationals who are UK-domiciled face UK inheritance tax (IHT) at 40% on worldwide assets above the nil-rate band — regardless of South African residence. South Africa imposes its own estate duty (20% below ZAR 30m, 25% above). The UK-South Africa DTA covers income tax but does not cover estate/inheritance tax in the same way, so careful domicile planning is needed for those with significant assets in both countries. Acquiring a South African domicile of choice requires deliberately severing ties with the UK as a permanent home.

Frequently asked questions about UK taxes in South Africa
Do I still owe UK tax after moving to South Africa?
As a UK non-resident (under the SRT), you only owe UK income tax on UK-source income: UK rental income, UK government pensions, the State Pension, UK capital gains on UK residential property, and certain UK investment income. South African income is not UK-taxable for a UK non-resident.
Is my UK pension taxed in South Africa or the UK?
UK government service pensions (civil service, NHS, teachers', armed forces) remain taxable only in the UK under the DTA. Private and occupational pensions are generally taxable in South Africa for South African residents (with credit for UK tax withheld). The UK State Pension is taxable in the UK. Each pension is assessed individually against the treaty.
I want to transfer money from the UK to South Africa — are there restrictions?
South Africa's exchange control rules regulate inward foreign investment and outward transfers. Bringing in foreign income (including UK pensions, rental income, or investment proceeds) is generally permitted but must be reported to an authorised dealer. Transferring funds out of South Africa is subject to annual allowance limits. While these are South African regulatory matters (not UK tax), they interact with your UK income sources and we flag the relevant considerations.
Do I need to file a UK Self Assessment from South Africa?
For the year you leave the UK, yes. After that, you need to file annually if you have UK-source income: UK rental property, UK pensions, UK capital gains on UK property, or other UK-source items. Many UK nationals in South Africa have ongoing UK filing obligations from rental properties or pension income.
