South Africa is one of the few countries where the decision to invest in US shares starts with an exchange control question. Money leaving the country is counted against allowances that the Reserve Bank sets and SARS polices, and a large part of the market avoids the question entirely by buying rand-priced ETFs on the JSE that hold offshore funds. Once the money is invested, a tax treaty with the US, SARS's rules for foreign dividends and gains, and two estate taxes shape what you keep. This guide takes each in turn for South African residents, with the limits in force in November 2026. South African law settles what is allowed and how the returns are taxed; check large or unusual moves with your bank, SARS or a South African tax practitioner. The main guide to investing from abroad covers what is common to every country.
Offshore account or JSE feeder ETF?
A JSE-listed feeder ETF is simpler and uses none of your allowances, while a direct offshore account takes more admin but holds US shares in your own name, in dollars.
A feeder ETF is a South African collective investment scheme that puts nearly all its money into one offshore fund, often an Irish-domiciled UCITS ETF tracking the S&P 500, the Nasdaq-100 or a world index. You buy it on the JSE in rand through any local stockbroking account. The fund manager uses its own offshore capacity, so your discretionary and foreign capital allowances are untouched, and the units can sit in a tax-free savings account.
A direct account works differently. You move rand offshore under your allowances, convert to dollars and buy US-listed shares or funds through a broker abroad or a local platform with offshore custody. The money stays in dollars, and you can keep it invested abroad rather than bringing it home.
| Question | JSE feeder ETF | Direct offshore account |
|---|---|---|
| Uses your allowances | No | Yes |
| Currency you hold | Rand-priced units with dollar exposure underneath | Dollars |
| US dividend tax | Usually 15% inside an Irish fund | 15% with a W-8BEN |
| US estate tax on your holding | No | Yes for US-domiciled holdings above $60,000 |
| Fits in a tax-free savings account | Yes | No |
| Typical costs | Fund fees and JSE spreads | Conversion margin, transfer fees and broker charges |
Local firms that arrange either route are financial services providers licensed by the FSCA, so check the provider's FSP number on the regulator's register before you hand over money.
How much money can you take offshore to invest?
Under the single discretionary allowance you can send R2 million per calendar year, and the foreign capital allowance adds R10 million per calendar year, once SARS approves the transfer.
The discretionary allowance can be used for any legal purpose abroad, including investment, and your bank processes it without a SARS approval. It rose from R1 million on April 8, 2026, under a Reserve Bank exchange control circular. The foreign capital allowance requires an Approval International Transfer from SARS first. SARS checks your tax compliance before issuing it and asks for a statement of your assets and liabilities.
Together the two give an adult resident R12 million of offshore capacity a calendar year. Anything above that needs approval from the Reserve Bank's Financial Surveillance Department through your bank. Each spouse has a separate set of allowances, which matters for couples planning a larger move.
Keep the paperwork. Your bank records which allowance each transfer used, and that record should agree with what you later declare to SARS. An AIT application is also easier when your records of earlier transfers and investment income are complete.
What the US withholds under the treaty
The US-South Africa income tax treaty lowers US withholding on dividends paid to South African residents, as long as the broker holds a valid Form W-8BEN with your South African tax number.
| Country | Tax treaty | Dividends (most investors) | Dividends (10%+ corporate owners) | Interest |
|---|---|---|---|---|
| South Africa | Yes | 15% | 5% | 0% |
Without the form the payer applies the statutory rate, which is 30% on US-source dividends, unless a tax treaty sets a lower rate, so on dividends the paperwork alone is worth 15 percentage points. A signed W-8BEN remains valid until the last day of the third calendar year after the year it is signed, and the W-8BEN guide explains which treaty article and rate to enter. The 5% rate is for companies owning at least 10% of the paying company, so it does not apply to individual portfolios.
Interest is taxed at 0% under the treaty, and Treasury interest is usually exempt for nonresidents anyway. Share sales are generally free of US tax unless you were physically present in the US for 183 days or more during the year.
Irish-domiciled funds get the same 15% on US dividends, because the US-Ireland treaty sets that rate for the fund itself. For a South African, the treaty therefore removes most of the dividend argument for Irish funds, and the case for them rests on estate tax, which is covered below. The comparison of US and Irish-domiciled ETFs sets out the other differences.
How does SARS tax US dividends?
As foreign dividends: most are taxable at a maximum effective rate of 20%, and the US tax already withheld can be claimed as a credit.
For an individual owning less than 10% of the foreign company, which covers any portfolio of US shares or ETFs, part of each foreign dividend is exempt so that the effective rate tops out at 20%, against a top marginal rate of 45%. Below the top bracket the effective rate scales down: about 16% at the 36% bracket and 8% at the 18% bracket. SARS allows no deductions for costs of earning foreign dividends.
The credit for US tax is limited to the South African tax on the same dividend. At the top bracket, SARS's 20% exceeds the US 15%, so you pay the 5% difference. At lower brackets the US tax can exceed what SARS would charge, and the excess is not refunded. That makes the W-8BEN essential: without it the US takes 30%, and SARS will credit only up to its own tax.
Declare foreign dividends, the US tax withheld and any gains in your annual return. The 2027 tax year runs from March 1, 2026 to February 28, 2027, and SARS publishes the filing dates each season.
How are gains on US shares taxed in South Africa?
SARS includes 40% of your net capital gain for the year in taxable income, after an annual exclusion of R50,000, so the top effective rate is 18%.
South Africa taxes residents on worldwide gains, and the US normally leaves them untaxed, so SARS's tax is usually the only one. The annual exclusion applies to your total net gain across all assets, local and foreign.
The calculation has one rule that works in your favour. An individual who buys and sells an asset in the same foreign currency works out the gain in that currency first and then converts it to rand, at the spot rate on the day of sale or the average rate for the tax year. A fall in the rand between purchase and sale does not, by itself, create a taxable gain, and a stronger rand does not create a deductible loss.
Tax-free savings accounts take gains out of the calculation entirely. Contributions are limited to R46,000 a year from March 1, 2026 and R500,000 over a lifetime, with a 40% penalty on any excess. Only accounts from South African providers qualify, which is where JSE feeder ETFs fit.
Worked example: a US ETF in a South African portfolio
Worked example: $10,000 in an S&P 500 ETF yielding 1.3%, bought at an illustrative R17 per dollar
- Cost: $10,000, or R170,000, sent under the discretionary allowance
- Yearly dividends: $130
- US withholding at the 15% treaty rate: $19.50
- SARS tax at the 45% bracket: 20% of $130 = $26.00, less the $19.50 credit, so $6.50 more is due and $104 is kept
- SARS tax at the 36% bracket: 16% of $130 = $20.80, less $19.50, so $1.30 more is due and $108.70 is kept
- Without a W-8BEN: $39 withheld, SARS credits only $26 at the top bracket, and $91 is kept
- Sale after the ETF rises to $13,000: a $3,000 gain at an illustrative R18 on the sale date is R54,000; after the R50,000 exclusion, R4,000 remains, 40% of it (R1,600) is taxable, and at 45% the tax is R720
The example ignores fees and assumes no other capital gains that year. To rerun it with current numbers, the SPY data page tracks one big S&P 500 fund, and the basics of dividend investing include how a yield is quoted.
What happens to US shares in a South African estate?
Two taxes can apply: US estate tax on US-domiciled holdings above $60,000, and South African estate duty on your worldwide estate, with a credit for the US tax.
For the US side, the threshold is $60,000 of US-situated assets, and the unified credit for nonresidents is $13,000, which offsets the tax on the first $60,000 of US assets. South Africa and the US have an estate tax convention signed in 1947 and in force since July 15, 1952. Unlike the US treaty with Canada, it gives no larger, prorated US credit, so the US tax is calculated as for any other nonresident. What it does is let South Africa, as the country of domicile, credit the US tax against its own duty on the same property.
SARS levies estate duty on the worldwide property of residents. An abatement of R3.5 million comes off the net estate, and duty is 20% on the first R30 million of the dutiable amount and 25% above that.
Worked example: $200,000 of US-domiciled ETFs in a South African estate, shown in dollars for simplicity
- Tentative US estate tax on $200,000: $54,800
- Less the $13,000 credit: $41,800 of US estate tax
- South African duty on the same shares at 20%, assuming the estate is above the abatement: $40,000
- Credit for the US tax, capped at that duty: $40,000, so no South African duty remains on those shares
- Total on the shares: $41,800, instead of $81,800 with no credit
- Left to a surviving spouse: the bequest is deductible for estate duty, so there is no duty to absorb the US tax, and the full $41,800 remains a cost
JSE feeder ETFs and Irish-domiciled funds sit outside the US estate tax, and so do US bank deposits not connected with a US business. The guide to US estate tax for nonresidents explains Form 706-NA and the transfer certificate executors need.
What does the rand do to your dollar returns?
It adds a second return on top of the share price: a weaker rand lifts the rand value of dollar assets, and a stronger rand cuts it.
When this page last refreshed, the mid-market rate was 1 USD = 16.7140 ZAR (Nov 2, 2026), and the USD to ZAR converter shows recent movement. Suppose a $10,000 holding bought at R17 is flat in dollars. If the rand strengthens to R15.30, the holding is worth R153,000, 10% less than it cost; at R18.70 it is worth R187,000. The two rates are examples only, not a view on where the rand is heading.
Because of the capital gains rule above, SARS ignores the currency part of that move when you sell. The rand still matters for spending, though, so measure progress in rand. Banks add a margin to the mid-market rate when they convert; compare quotes against the true mid-market rate before using a large part of an allowance. The currency risk guide discusses whether hedging is worth it over different time horizons.

Risks for South African investors
- Exchange control mistakes. Sending more than an allowance permits, or using the discretionary allowance for money that needed an AIT, can lead to penalties and difficulty bringing funds home. Ask your bank which allowance each transfer uses.
- Double estate exposure. A large US-domiciled portfolio can face US estate tax that South African credits only partly absorb, especially when assets pass to a spouse.
- Currency risk. The rand can move 10% or more in a year, which can erase or double a year's return measured in rand.
- Provider risk. Check FSCA authorisation for local firms and the regulator, custodian and investor protection scheme of any foreign broker.
- Tax filing risk. SARS receives information on many foreign accounts. Leaving foreign dividends or gains off a return invites penalties and interest.
- Rule changes. The discretionary allowance rose from R1 million to R2 million on April 8, 2026, and the tax-free savings limit changed on March 1, 2026. Recheck the current figures before a large transfer.
SARB and SARS rules, not general guidance, decide what you may invest and what tax you owe at home. Before moving a large sum, confirm the allowance with your bank and ask a registered South African tax practitioner to check the SARS side.
