AOW, pension and tax in South Africa: the source-state treaty
The Netherlands keeps taxing your AOW, pension and annuity — the 2005 treaty is a source-state treaty without a threshold. But South Africa largely exempts foreign pensions, so you don't pay twice. The AOW goes with you at 100% (in rand), and the exemption that carries the sum was already up for debate once in 2025 — the key point to monitor on this corridor.
Whoever takes the Southern European pension logic to South Africa overestimates their income by thousands of euros a year. The treaty works the other way round here — and yet the sum works out neatly, for a reason that appears on almost no Dutch-language site. This article completes it.
The treaty: the source may tax, without a threshold
Article 17 of the 2005 treaty lets pensions, annuities and social security benefits be taxed in the country they come from. No threshold amount, no exceptions for small pensions: the Netherlands simply withholds wage tax on your AOW (the Dutch state pension), your occupational pension and your annuity, even if you have lived in the Cape for years. An exemption statement for wage tax is not on the cards, and an ABP pension remains Dutch via article 18 in any case.
The other half: South Africa exempts
Why you nevertheless don't pay twice: South African tax law exempts foreign social security benefits and foreign pensions for service outside South Africa — in proportion to that foreign service, which for a Dutch career amounts to virtually everything. SARS has set that out in its own interpretation note. The net result: on your pension income you simply pay the Dutch rate, and South Africa doesn't tax on top.
One caveat you need to know: in 2025 there was a proposal to scrap that exemption. It was withdrawn at the end of that year, but the treasury keeps looking at it. This is the key point to monitor for this destination — if the exemption ever falls, the sum changes fundamentally.
The AOW: fully exported, but in rand
The social security agreement with South Africa obliges the Netherlands to export the AOW in full: a single person keeps the full 70%, without the reduction that applies outside treaty countries. The accrual does stop on the day you leave — every year before your AOW age outside the Netherlands costs 2%, unless you apply for voluntary continuation with the SVB within a year of departure.
And the detail that affects your monthly budget: in South Africa the SVB pays out in rand. Your basic income thereby acquires an exchange-rate risk. The usual solution: calculate fixed costs in rand, keep a buffer in euros in the Dutch account, and exchange in instalments.
Working and assets
Whoever goes to work or runs a business in South Africa falls fully under South African taxation — 18 to 45 percent — according to the treaty's rules on the state of employment and permanent establishment. Investment income has the usual division: Dutch dividend tax remains as a limited withholding tax, rent from Dutch property remains taxed in the Netherlands, and South Africa as country of residence taxes worldwide income with a credit. And remote workers remember the 183-day threshold for SARS registration.
What else the Netherlands doesn't let go of
The year of departure comes with an M return. An annuity, pension entitlement or substantial shareholding travels with a protective assessment — and outside the EU the deferral of payment is not automatic: you apply for it, and the Belastingdienst can demand security, up to and including a bank guarantee. That is the heaviest fiscal moment of this corridor; get guidance there. With this list you know exactly what to ask the tax adviser.

Healthcare in South Africa: medical aid, gap cover and the age sum
There is no healthcare treaty, no S1 and no CAK: you insure yourself privately, before departure, because the visa requires it. Private healthcare in the cities is excellent — the system around it you have to learn: medical aid, designated providers, gap cover, and a premium that rises with age. Whoever plans their old age here does the age sum first.

Living in South Africa: neighbourhoods, estates and what buying costs
Rents are a third to half of the Dutch level and foreigners buy freely, with a transfer duty that only starts above R 1.21 million. But the first choice is not the house — it is the neighbourhood, because safety and value are hyperlocal there. Rent for six months first; you can always buy later.

When you need a migration adviser — and when you don't
For the ordinary journey an adviser is not compulsory, and the organising you can do yourself. But there are situations in which you bring one in without hesitation. The honest distinction, plus how to recognise a registered adviser.
