AOW, pension and tax in South Africa: the source-state treaty, the exemption of section 10(1)(gC) and the AOW that arrives in rand
The Netherlands keeps taxing your AOW, pension and annuity, because the treaty of 2005 allocates pensions and social security payments to the source state, without a threshold. You do not pay twice: the South African Income Tax Act exempts foreign social security payments and pension for service outside South Africa. The accrued AOW is exported in full, but the SVB pays it in rand, and an annuity or company travels with a protective assessment for which the tax office can demand security outside the EU.

If you live in South Africa, the Netherlands taxes your AOW and your pension. South Africa does not tax on top, so what it costs is the Dutch rate, and no more.
Three things to know up front:
- Your accrued AOW and your pension do come with you, but the treaty of 10 October 2005 lets pensions, annuities and social security payments be taxed in the country they come from, without a threshold amount.
- That South Africa does not tax on top is in the South African Income Tax Act itself. Section 10(1)(gC) exempts payments under the social security system of another country, and pension for service outside South Africa in proportion to that service.
- The trap is on the Dutch side. An annuity, pension entitlement or company travels with a protective assessment: an assessment the tax office imposes on emigration. Outside the EU the tax office can demand security for it, such as a bank guarantee.
Who taxes what?
| Income | Treaty article | Who may tax |
|---|---|---|
| AOW and other social security payments | 17, second paragraph | the Netherlands, as source state |
| Occupational pension and annuity | 17, first paragraph | the Netherlands, as source state |
| Salary from employment in South Africa | 14 | South Africa, where the work is done |
| Rent from a Dutch home | 6 | the Netherlands, where the home stands |
| Dividend from the Netherlands | 10, second paragraph | the Netherlands up to 10% withholding; South Africa as state of residence |
Article 17 has no exception for small pensions and no exemption statement: the Netherlands simply withholds wage tax on your AOW, your occupational pension and your annuity, even when you have lived in the Cape for years. Article 18 covers only salaries from government service, expressly "not being pensions", so a government pension falls under article 17 too.
Why do I not pay twice?
Because South African law exempts on its side. Section 10(1)(gC) of the Income Tax Act excludes two things from normal tax. Under (i) that is any amount a resident receives under the social security system of another country, such as your AOW. Under (ii) that is a pension, annuity or lump sum from a foreign source as consideration for work outside South Africa.
SARS, the South African tax authority, explains in Interpretation Note 104 how the latter is calculated: the exempt portion is the foreign service divided by the total service, times the amount received. For a Dutch career that comes down to almost everything. The net result: on your pension income you pay the Dutch rate, and South Africa does not tax on top.
What does someone pay who works or invests there?
Whoever takes a job in South Africa falls fully under South African tax under article 14. For the 2027 tax year (1 March 2026 to 28 February 2027) SARS starts at 18% up to R 245,100 of taxable income and ends at 45% above R 1,878,600. With that come a primary rebate of R 17,820, and additional rebates of R 9,765 from 65 and R 3,249 from 75.
SARS treats you as a resident if South Africa is your ordinary residence, or if you meet the physical presence test: more than 91 days in the tax year, more than 91 days in each of the five preceding years and more than 915 days in those five years together.
Investment income follows the usual division. Dutch dividend keeps a withholding of at most 10% under article 10: tax the Netherlands already deducts on payment. Rent from Dutch property stays Dutch under article 6. Whoever keeps working remotely for a Dutch employer reads in working in South Africa when SARS registration becomes mandatory.
How does my AOW arrive?
The social security treaty of 16 May 2001 forbids the Netherlands in article 6 from limiting a benefit only because you live in South Africa: the accrued AOW is exported in full. Accrual does stop on departure. How you repair that is in your AOW accrual stops.
And then the detail that touches your monthly budget. The SVB transfers the AOW in euros to Citibank, at most € 0.48 per payment. But the SVB pays it out in South Africa not in euros but in rand. As a result the net amount differs with every payment because of the exchange rate. How you absorb that on your South African account is in banking and paying in South Africa.
What does the Netherlands not let go of?
Outside the EU the deferral for the protective assessment is not automatic. The tax office imposes it on the pension, annuity or substantial shareholding you built up in the Netherlands, grants deferral on request and can demand security: a bank guarantee, a mortgage or a pledge. That is the heaviest tax moment of this corridor; get guidance there.
For pension and annuity the assessment runs for ten years. If you keep to the Dutch rules in that time, so no surrender, you can ask for remission afterwards. For a substantial shareholding, lifelong deferral has applied since 15 September 2015, with settlement on sale, dividend or the end of the company. The year of departure itself goes with an M return; the step-by-step plan puts those two side by side in the phase closing the Netherlands.
In Vertrekklaar this is phase 3 of 5 of the journey, step 3.2: the same steps, but for your situation — in your order, tickable, and with the deadlines watched. See the whole journey to South Africa or go straight to step 3.2 in the open plan.

Healthcare in South Africa: no treaty, a medical aid that may not refuse you, and the waiting periods of three and twelve months
South Africa is not on the list of treaty countries: no S1, no CAK, your Dutch basic insurance stops on deregistration and the visa asks for proof of medical cover. A registered open medical aid may not refuse you, but may impose a general waiting period of three months and a condition-specific waiting period of twelve months, and a late-joiner penalty for whoever joins at 35 or older. The prescribed minimum benefits are the safety net.

AOW, pension and tax in Argentina: two treaties, and the AOW goes with you in full
The Netherlands has a tax treaty and a social security treaty with Argentina. As a result your AOW goes with you in full, also as a single person. The Netherlands taxes the AOW and an ABP pension; an ordinary occupational pension and an annuity are taxed only by Argentina. There, as a foreigner, you only become tax resident after twelve months.

AOW, pension and tax on Aruba: what the Kingdom does arrange
Aruba is the mildest destination outside Europe for your old age: the accrued AOW goes with you in full, with the single-person rate and the allowance, and the 1964 Tax Arrangement for the Kingdom lets the country of residence tax pension from former employment. What stops (the accrual), what begins (the Aruban AOV), what Aruba charges, and where the sharp edges are: the protective assessment, government pension and lump-sum surrender.
