Selling Cape Town Property as a Non-Resident: Section 35A Withholding, NR03 and the Exit Cost (2026)

In September 2026, UK podcaster Steven Bartlett listed his Bishopscourt estate in Cape Town at R189,000,000, having reportedly bought it for R93,300,000 in 2024 (Source: SA People, 2026-09-28; REI.co.za, 2026-09-28). The headlines focus on the doubling. For a foreign seller, the number that matters is different: on completion, the purchaser is legally required to withhold R14,175,000 and pay it to SARS — and the 7.5% is charged on the full purchase price, not on the profit.

That is section 35A of the Income Tax Act. It never appears on the day you buy in Cape Town; it only appears on the day you sell. So most foreign buyers never model it at entry. For anyone selling property in South Africa as a non-resident, this article sets out the four exit costs of a Cape Town sale: how the withholding is calculated, how an NR03 directive can reduce it, what the 21 business days actually measure, and how the proceeds leave South Africa.

Why does a Cape Town sale trigger a deduction before transfer?

Because South African law places the collection duty on the buyer, not the seller. Section 35A has applied since 1 September 2007: any person who must pay a non-resident seller for the disposal of South African immovable property has to withhold a statutory percentage from the amount payable and hand it to SARS (Source: SARS, Amounts to be Withheld When a Non-Resident Sells Immovable Property, updated 2025-10-02).

The practical consequence for a foreign owner in Cape Town is blunt: on transfer you do not receive the sale price — you receive the sale price minus the withholding. On a R8,000,000 free-standing house in the Southern Suburbs, the cash you receive on the day is capped at R7,400,000. The other R600,000 sits with SARS until assessment.

The money is a prepayment, not a penalty

SARS is explicit about the character of the amount in a South African disposal: it is an advance payment towards the seller's liability for normal tax in the year of assessment in which the property is disposed of. In other words, it is your own tax, pre-funded. The final figure is settled on assessment — overpaid amounts are refundable, shortfalls are payable.

This is where Cape Town sellers misjudge the cash flow. The withholding is calculated on the price; the tax is calculated on the gain. A Constantia house bought for R6,000,000 in 2019 and sold for R11,000,000 in 2026 carries a withholding of R825,000 on the full price, while the taxable gain is a fraction of that. The difference can be locked up for months.

Is the R2,000,000 threshold a deduction or a trigger?

It is a trigger, not a deduction. For Cape Town sales, SARS states it plainly: "Where the value of the property exceeds R2 million, the withholding amount applies to the full purchase price, without regard to the R2 million threshold" (Source: SARS, Guide to Amounts to be Withheld, 2025-10-02). You do not withhold on the excess above R2,000,000 — you withhold on everything.

Conversely, if the amounts payable by the purchaser to the seller and any other person on the seller's behalf, in aggregate, do not exceed R2,000,000, section 35A does not apply at all. In Cape Town's price bands that line is real: a R1,950,000 city-centre studio and a R2,050,000 Southern Suburbs townhouse differ by about 5% in price, yet only one of them triggers a six-figure withholding.

Four worked examples, from R2,000,000 to R189,000,000

The Cape Town Bishopscourt figure, R14,175,000, is simply R189,000,000 × 7.5%. The obligation sits with the purchaser and is not negotiable between the parties.

Does the deposit get withheld?

Not immediately, but conditionally. A deposit paid to secure the disposal is excluded from withholding until the agreement becomes unconditional; once it does, the amount that should have been withheld from the deposit is withheld from the first following payments instead. In Cape Town practice the agreement usually carries bond-approval and inspection conditions, so the withholding clock effectively starts when those conditions are met — typically 30 to 45 days after signature.

Can NR03 reduce or cancel the withholding — and what are the 21 business days?

You can apply, but nothing is automatic. A non-resident seller of Cape Town property who believes the actual tax liability is lower than the statutory rate may request a tax directive on the SARS NR03 form. SARS lists three statutory grounds only: security has been furnished for the tax, the seller is not subject to tax on the disposal, or the seller's actual liability is less than the statutory percentage. SARS gives concrete examples — the seller is fully exempt, the individual has a low taxable income, or the property was disposed of at a loss (Source: SARS, Non-resident sellers of immovable property, 2026-08-19).

The most common Cape Town situation is not on that list: "I barely made a profit, why is the withholding based on the full price?" The answer is that the withholding is on the price, not the gain — unless an NR03 is granted. The application must be submitted with the offer to purchase, the tax calculation and supporting documentation, to nres@sars.gov.za or another method listed on the form.

21 business days is not the payment deadline

This is the most expensive misunderstanding in circulation. In South African practice, SARS publishes two different clocks, and they mean different things:

• 21 business days is the processing time for an NR03/NR02 application ("The directive application is generally processed within 21 business days").
• 14 days / 28 days is the payment deadline for the purchaser — within 14 days after the amount was withheld if the purchaser is a resident, or 28 days if the purchaser is a non-resident (Source: SARS, Guide to Amounts to be Withheld, 2025-10-02).

Those numbers differ by an order of magnitude. A buyer who assumes "21 business days to spare" when the real deadline is 14 days absorbs a 10% penalty plus interest — and then comes back to the seller. This is precisely why Cape Town conveyancers press both parties for NR02/NR03 documents early in the transfer process.

Sequencing an exit

What happens without NR03 — who is liable?

Liability cascades through three layers, and the penalty is not waivable. This is the hardest part of section 35A, and the real reason a Cape Town buyer keeps chasing documents.

Layer one: the purchaser is personally liable

In a South African disposal, a purchaser is personally liable if they knew, or should reasonably have known, that the seller is a non-resident, and must pay SARS by the date payment should have been made (Source: SARS, Guide to Amounts to be Withheld, 2025-10-02). Note "should reasonably have known": a foreign passport, an offshore address, or payment from an offshore account makes that defence very hard to run.

Layer two: the conveyancer and estate agent must give written notice

Any South African conveyancer or estate agent entitled to remuneration on the disposal must notify the purchaser in writing, before any payment to the seller, that the seller is a non-resident and that section 35A may apply. If they should reasonably have known and failed to notify, they become jointly and severally liable, capped at the amount of their own remuneration. If they did notify, the purchaser cannot claim ignorance.

Layer three: 10% penalty plus interest, and interest cannot be waived

• Interest at the prescribed rate runs from the day after the payment deadline until SARS receives the money;
• A penalty equal to 10% of the amount is payable, in addition to any other penalty or charge;
• SARS adds the decisive line: "No provision is made to waive interest."

That sentence is why "transfer first, settle the tax later" does not work in Cape Town. The cost of settling later only grows.

What if the price is in a foreign currency?

For a Cape Town sale, the withheld amount is translated into rand at the spot rate on the date it is paid over to SARS — not the date of signature. For a Taiwan-based buyer, the currency exposure therefore lands on the payment date, which for 2026 rand volatility deserves a buffer in the model.

How does the 7.5% relate to capital gains tax?

The withholding is a prepayment; CGT is the final liability. For South African purposes, SARS describes the withheld amount as an advance against the seller's normal tax for the year of assessment in which the disposal occurs. South Africa capital gains tax is computed under the Eighth Schedule, included in taxable income at the inclusion rate, and taxed at the applicable rate.

Maximum effective CGT rates for 2026/27

(Source: South African Revenue Service, Budget 2026 Frequently Asked Questions, 2026-03-20)

The same South African Treasury and SARS document confirms exclusions effective 2 March 2026: the annual exclusion rises to R50,000 (from R40,000) and the primary residence exclusion to R3,000,000 (from R2,000,000). Whether the primary residence exclusion is available to a particular non-resident depends on the Eighth Schedule requirements and the facts; it cannot be assumed.

The disposal happens on signature, not on registration

This is the sentence every Cape Town seller should memorise: for property, the CGT disposal occurs when the sale agreement is signed, not when transfer is registered at the Deeds Office. "If you sign a sale agreement in February 2026, the gain falls in the 2025/26 tax year (ending 28 February 2026), even if transfer only occurs in May 2026." (Source: SARS, Budget 2026 FAQ, 2026-03-20)

Meanwhile the section 35A withholding happens at payment. A November signature with a February transfer can straddle two tax years, so a Cape Town exit needs the cash flow planned in two stages.

What if the seller never files?

If the seller does not submit a South African return within 12 months after the end of that year of assessment, the amount already paid becomes a sufficient basis for an assessment under section 95 of the Tax Administration Act. In plain terms: no return means SARS treats the withheld amount as your final liability and does not volunteer a refund.

How do the proceeds legally leave South Africa?

Property disposal proceeds fall under BoP category 510 01. That is the number that matters when the money leaves after a Cape Town sale. The South African Reserve Bank's revised balance-of-payments categories took effect for industry on 11 August 2026, adopting SADC-harmonised codes and the IMF's BPM7 framework (Source: Nedbank, FinSurv BoP categories guide, 2026-08; SARB Quarterly Bulletin, Box 2, 2026-09).

(Source: South African bank Nedbank, FinSurv BoP categories guide, Version 20250622/v003, 2026-08)

One caveat matters: the final code is determined by the bank's authorised dealer based on the actual nature of the transaction, not self-selected by the seller. The table tells you where your transaction belongs; it is not a form to copy. That is why the first Cape Town repatriation to be rejected is rarely a wrong code — it is insufficient proof of the nature of the transaction. Keep the sale agreement, the completed transfer evidence, the SARS withholding receipt, and the exchange control declaration.

The three most common rejection points

• No SARS withholding receipt: the bank will confirm the section 35A obligation is settled before processing a 510 01 payment.
• Inconsistent description of the transaction: the agreement says one thing, the remittance form another.
• Beneficiary account not in the seller's name: paying to a family member in Taiwan needs additional authority documents, and Cape Town banks check this closely.

Budget the whole chain, not one step: section 35A withholding, CGT assessment, and BoP repatriation review are three separate processes that in Cape Town practice take roughly three to six months end to end.

FAQ

Is the section 35A withholding 7.5% of the price or of the profit?

Of the price. When a non-resident sells South African immovable property for more than R2,000,000 in aggregate, the purchaser withholds 7.5% (individual), 10% (company) or 15% (trust) of the full purchase price. The amount withheld is an advance against normal tax and is reconciled on assessment against the actual capital gain.

What is NR03 and is it always granted?

NR03 is the seller's application for a South African tax directive reducing or cancelling the withholding. SARS assesses it on three statutory grounds only: security furnished, no liability on the disposal, or actual liability below the statutory percentage. It is not granted automatically, and SARS generally takes 21 business days to process it.

Are the 21 business days the deadline for paying SARS?

No. 21 business days is the South African Revenue Service's processing time for an NR03/NR02. The purchaser's actual payment deadline is 14 days after withholding (28 days where the purchaser is a non-resident). Late payment attracts a 10% penalty plus interest, and SARS states that no provision is made to waive interest.

What is the maximum capital gains tax on a South African property sale?

For South Africa's 2026/27 year, the maximum effective rates are 18% for individuals and special trusts, 21.6% for companies, and 36% for other trusts. From 2 March 2026 the annual exclusion is R50,000 and the primary residence exclusion is R3,000,000; availability to a non-resident depends on the facts and SARS's determination.

Which code is used to send sale proceeds out of South Africa?

Repatriation of proceeds from a non-resident individual's Cape Town property disposal maps to BoP category 510 01 (Disinvestment of property by a non-resident individual). The final code is assigned by the bank's authorised dealer based on the transaction. Keep the sale agreement, transfer evidence and SARS withholding receipt.

Does CGT arise on signature or on registration?

On signature. For South African property, the disposal occurs when the sale agreement is signed, not when transfer is registered at the Deeds Office. Signing in February 2026 places the gain in the 2025/26 tax year even if transfer completes in May 2026.
