Part 3 – Turning Rand Strength into Sterling Retirement Income , and Leaving a Clean Legacy

How South African investors can build UK rental income without leaving their family an avoidable tax problem

Part 1 looked at the opportunity created by the Rand’s recovery.

Part 2 considered what could strengthen or weaken that opportunity from here.

Now comes the practical question: how do you turn stronger Rand purchasing power into a sterling rental-income stream and eventually pass the asset to your children without leaving behind unnecessary tax, confusion or legal problems?

The principle is straightforward. A carefully selected UK rental property can produce income in pounds throughout retirement and remain as a tangible asset for the next generation.

But it must be bought properly.

This is not a pension product, and the rental income is not guaranteed. Property values can fall, tenants can leave and unexpected costs arise. It is better described as a sterling retirement-income strategy: an asset intended to produce regular rental income while also providing the possibility of long-term capital growth and a future family legacy.

Buy the Income, Not the Brochure

The advertised gross yield is only the starting point.

For example, a £500,000 property producing a 6% gross yield would generate £30,000 a year in rent. That sounds attractive, but it is not the amount the owner gets to spend.

From the gross rent, the investor may need to pay letting and management fees, service charges, insurance, maintenance, safety certificates, accountancy costs, mortgage interest and the cost of periods when the property is empty.

A property that looks impressive at 7% gross may produce less usable income than a better-managed property yielding 6%.

The correct question is therefore not:

“What is the advertised yield?”

It is:

“What income should remain after every realistic cost has been included?”

Before purchasing, investors should obtain independent rental comparisons and examine the development’s service charges, lease terms, building warranty, construction quality, local rental supply, tenant profile and resale market.

Modern apartments may be easy to manage remotely, but a high service charge can consume a significant part of the rent. Older properties may have lower service charges but require more maintenance. Neither is automatically better; the figures must be examined property by property.

Move the Money Properly

South African residents must also ensure that the capital is transferred offshore through the correct channels.

Following changes introduced during 2026, South African resident adults may generally transfer up to R2 million per calendar year under the Single Discretionary Allowance. A separate foreign capital allowance of up to R10 million per individual per calendar year remains available, normally subject to the required South African tax-compliance process. Transfers beyond the permitted allowances require additional approval.

This needs to be considered before reserving a property. A buyer should not commit to a completion date without first confirming that the funds can be transferred, that the source-of-funds documentation is available and that any required tax-compliance approval has been obtained.

Currency conversion can then be completed in one transaction or staged over time. The objective is not to guess the perfect exchange rate but to prevent an avoidable currency movement from disrupting the purchase.

Decide How to Own It Before You Buy It

A UK property may be held personally, jointly with a spouse or civil partner, or through a company.

There is no single structure that is best for everyone.

Personal ownership is often simpler and less expensive to administer. Company ownership may offer advantages in certain circumstances, particularly where borrowing is involved or rental profits will be retained for further investment. However, a company brings additional accountancy, legal and tax obligations.

Most importantly, putting UK residential property into a company does not automatically remove it from UK Inheritance Tax. UK rules can bring the value of residential property held through companies and other entities back within the IHT net.

The ownership structure should therefore be compared before contracts are exchanged. Moving an existing property from personal ownership into a company later can create further tax, financing and legal costs.

Four Tax Points to Understand

The first tax cost normally arises when the property is purchased.

A buyer who is treated as non-UK resident for Stamp Duty Land Tax purposes will generally face the 2% non-resident surcharge when purchasing residential property in England or Northern Ireland. Where the buyer already owns a home, including a home outside the UK, the higher rates for purchasing an additional property may also apply. The non-resident surcharge is charged on top of the other applicable residential rates.

The second tax point is the rental income.

The UK’s Non-resident Landlord Scheme applies where the landlord’s usual home is outside the UK. The landlord can apply to HMRC for approval to receive the rent without tax being deducted by the letting agent, but the income must still be declared and any UK tax due must still be paid. Where a couple own the property jointly, each owner is treated separately and may need their own HMRC approval.

The third tax point is South Africa.

A South African tax resident is generally taxed on worldwide income, so UK rental income must normally also be reported to SARS. The general principle is that qualifying foreign tax paid may be claimed as a credit against the related South African tax liability, preventing or reducing double taxation.

The fourth tax point arises when the property is sold.

A non-UK resident must report the disposal of UK property to HMRC, even where there is no tax to pay or the sale produces a loss. UK Capital Gains Tax may be payable on the taxable gain.

None of this makes UK property unsuitable. It simply means the purchase should be calculated using the real after-cost and after-tax position rather than the headline rent alone.

Inheritance Tax: The Simple Explanation

This is where unnecessary confusion often begins, so let us keep it clear.

The ordinary UK Inheritance Tax nil-rate band is currently £325,000 per person. It can apply to a pure buy-to-let property even if the owner has never lived in it. A married couple or civil partners may potentially have up to £650,000 of combined ordinary allowances. What normally does not apply to a pure investment property is the separate residence nil-rate band, because the owners have never occupied it as their home.

A Straightforward Example

Consider a legally married South African couple, neither of whom is a long-term UK resident, who own a UK rental property worth £600,000 as joint tenants.

They have never lived in the UK property. It has always been rented to tenants.

When the first spouse dies, their interest passes to the surviving spouse. In a straightforward case, the spouse or civil-partner exemption will normally prevent UK Inheritance Tax being charged on that transfer. The first spouse’s unused ordinary allowance may then transfer to the survivor.

When the second spouse dies, the estate could potentially have up to £650,000 of combined ordinary allowances.

Provided the UK property is still worth £600,000, the rest of the estate is straightforward and the allowances have not previously been used, the property may pass without UK Inheritance Tax in a straightforward case.

They do not need to have lived in the property to receive the £650,000 combined ordinary allowances.

Now suppose the property has increased in value to £800,000 by the second death. With £650,000 of ordinary allowances available, approximately £150,000 would remain exposed to IHT. At the standard 40% rate, that could produce a tax bill of approximately £60,000 before considering deductible debts, other assets, previous transfers and the precise circumstances of the estate.

That is why the planning should not stop on the day the property is purchased. Its value and the potential liability should be reviewed as the years pass.

The Pitfalls Families Need to Avoid

The first major trap is assuming that all couples receive the same treatment.

The transferable £325,000 allowance and spouse exemption apply to legally married couples and civil partners. They do not automatically apply to unmarried partners, regardless of how long they have lived together.

An unmarried couple may each have their own £325,000 allowance, but one partner cannot normally inherit the unused allowance of the other. A transfer between them on death also does not receive the normal spouse or civil-partner exemption.

The second trap is believing that joint ownership removes the property from the estate.

Joint tenancy allows the property to pass automatically to the surviving owner without passing under the deceased’s will. However, the value of the deceased’s interest is still included when calculating the estate for IHT purposes.

The third trap is assuming that company ownership solves the inheritance problem. It may change the way income and financing are taxed, but it does not automatically take UK residential property outside IHT.

The fourth trap is planning around today’s property value. A £600,000 property may sit comfortably below a couple’s potential £650,000 combined ordinary allowances today, but rental growth, improvements and general price inflation could push it above the threshold later.

The fifth trap is failing to coordinate the wills.

South African residents owning UK property should usually have appropriately drafted and coordinated UK and South African wills. They must be written so that one will does not accidentally revoke or interfere with the other.

For larger anticipated IHT liabilities, a suitably arranged life-insurance policy may provide money with which the heirs can pay the tax without being forced to sell the property quickly. This must be structured properly and should not be arranged without specialist advice.

One Important Warning for Former UK Residents

The UK changed its IHT rules on 6 April 2025.

The UK’s long-term residence rules, which took effect from 6 April 2025, can bring overseas assets within the IHT system for individuals with sufficient UK residence history, so former UK residents should get tailored advice.

This means a British expatriate living in South Africa, or anyone with a substantial history of UK residence, must not assume that only the UK rental property is relevant.

Their wider worldwide estate may also need to be reviewed.

For a South African investor without that UK residence history, the principal IHT concern will normally be the UK property and other UK assets.

The Best Way to Proceed

A sensible purchase should follow a clear order.

First, establish how much capital can legally and comfortably be transferred from South Africa without leaving the investor short of emergency funds.

Second, calculate the complete acquisition cost, including SDLT, legal fees, furnishing, mortgage costs and a reserve for unexpected expenses.

Third, obtain a genuine net-income projection that includes management, service charges, insurance, maintenance, voids, finance and taxation.

Fourth, compare personal, joint and company ownership before committing to the purchase.

Fifth, put the UK and South African tax reporting arrangements in place from the beginning.

Finally, coordinate the wills and review the potential IHT position while the numbers are still manageable, not many years later when the property has appreciated and the owners’ circumstances have changed.

Income Today, a Legacy Tomorrow

The attraction of this strategy is not simply that the Rand currently buys more pounds.

It is the opportunity to move part of a South African investor’s wealth into a different currency, a different economy and an income-producing tangible asset.

Done properly, the property can provide rental income throughout retirement and later pass to the family with a clear ownership structure, suitable wills and a planned approach to any eventual tax liability.

Done badly, the same property can leave the children with an unexpected tax bill, conflicting wills, an unsuitable company structure or the need to sell quickly.

The objective is therefore not merely to buy UK property.

It is to buy the right property, in the right ownership structure, with the right tax and estate planning around it, so it pays you in sterling while you are alive and passes as cleanly as possible when you are gone.

At Horizon, we help clients identify suitable UK developments, examine the commercial proposition and coordinate with appropriately qualified UK and South African professionals where specialist tax, legal, mortgage and estate-planning advice is required.

Use the Rand’s strength, but build the structure before you build the legacy.
