What situs taxes and estate duties mean for your investments and for your heirs.

 

For many South Africans, building wealth no longer stops at our borders.

Whether it's buying shares in global giants like Apple, Microsoft and Nvidia, investing in overseas property or holding international investment portfolios, offshore investing has become an essential part of wealth creation. It offers access to larger markets, broader investment opportunities, currency diversification and the ability to spread risk beyond the South African economy.

But while investors spend significant time considering investment performance, tax efficiency and exchange rate movements, there is one question that often gets overlooked:

 

What happens to my offshore assets when I die?

Most South Africans assume that if they pay tax in South Africa, only South African estate duty applies when they die. Unfortunately, global tax authorities don't see it that way.

A portfolio of US shares, a London apartment or certain European investments could potentially attract foreign death taxes even if you've never lived there.

This is known as situs tax: the idea that some countries tax assets simply because they're located there (see further below for more detail and examples). It's one of the most overlooked risks of offshore investing.

The good news is that with a little planning, these surprises can often be avoided. After all, the only surprise your heirs should receive is their inheritance and not an unexpected tax bill from a country they've never visited.

Before we get there, let's start with the tax most South Africans are already familiar with: estate duty.

 

South African estate duty: the tax you already know about

If you are ordinarily resident in South Africa, SARS generally taxes your worldwide estate when you die.

Estate duty is currently charged at:

  • 20% on the first R30m of your dutiable estate; and
  • 25% on the portion exceeding R30m.

For many investors, that's where the planning discussion starts. Unfortunately, it's also where it often ends.

But South Africa's estate duty system also offers several planning opportunities that, when used correctly, can significantly reduce your family's eventual tax burden.

Think of estate duty planning like a long game of chess. The goal isn't necessarily to eliminate taxes; it's to ensure more of your wealth reaches your loved ones rather than the tax authorities.

 

Estate duty planning opportunities every South African should know about

1. Don't forget your R3.5m head start

Every South African estate receives an estate duty abatement of R3.5m. In simple terms, the first R3.5m of your dutiable estate is effectively shielded from estate duty.

For married couples, the news gets even better.

If the first spouse to pass away does not fully utilise their abatement, the unused portion can generally be transferred to the surviving spouse. This can increase the available abatement in the surviving spouse's estate to up to R7m.

While it may not sound exciting, this is one of the simplest ways South African families can legitimately reduce their overall estate duty exposure.

2. The "everything to my spouse" rule

One of the most powerful estate duty relief provisions in South Africa applies when assets are left to a surviving spouse. Generally, assets bequeathed to a spouse qualify for a deduction when calculating estate duty in the estate of the first-dying spouse.

The practical result? In many cases, little or no estate duty is payable when the first spouse dies. There is typically another benefit too. Capital gains tax on those inherited assets is often deferred until the surviving spouse disposes of them or later passes away.

Of course, this doesn't mean the tax disappears forever. Think of it as pressing the snooze button rather than turning off the alarm. The tax consequences are often deferred, not eliminated, providing valuable liquidity and financial breathing room for the surviving spouse.

3. The power of small, consistent gifts

When people hear about estate duty planning, they often think about complicated structures and sophisticated tax strategies. But sometimes the simplest tools are the most effective.

South Africans may donate up to R150,000 per year without triggering donations tax.

On its own, R150,000 may not seem life-changing. But over 10, 20 or 30 years, these annual gifts can remove significant value from an estate.

The benefit becomes even more powerful when those assets grow in value after being gifted. Imagine planting a tree in someone else's garden. Not only have you moved the tree out of your estate, but all future growth will occur outside your estate as well.

Of course, every family's circumstances are different, and donations can have other tax implications. Professional advice should always be obtained before implementing a gifting strategy.

4. Retirement funds: the unsung estate planning hero

Many people view retirement funds purely as vehicles for retirement savings. But they are much more than that. Generally, benefits held in approved retirement funds do not form part of your dutiable estate for estate duty purposes.

For many investors, maintaining an appropriate portion of wealth within retirement structures can be a highly effective long-term planning strategy.

5. Trusts: managing tomorrow's growth

One of the biggest misconceptions about estate duty planning is that the problem is today's estate value. The bigger challenge is often future growth.

An estate worth R20m today could be worth substantially more in 20 years.

This is where trusts can play an important role. When assets are held in a properly structured trust, future growth may occur outside the founder's personal estate. Over time, this can significantly reduce the value exposed to estate duty.

However, trusts are not magic boxes that make taxes disappear. South African trust legislation contains numerous anti-avoidance provisions and trust planning requires careful structuring and ongoing administration. A trust should therefore be viewed as a valuable tool, rather than a universal solution.

6. Investment wrappers: not everything is as tax-efficient as it seems

Many investors assume that if an investment product offers tax advantages during their lifetime, it must also be beneficial from an estate duty perspective.

Unfortunately, that is not always true. While investment wrappers may provide income tax, capital gains tax or administrative efficiencies, they generally do not remove the underlying value from your estate. On death, the value of the investment wrapper is typically included in your estate for estate duty purposes.

The lesson? Don't assume a good income tax strategy automatically translates into a good estate duty strategy. They are different taxes and require different planning considerations.

 

When estate duty is only half the story

Even after carefully planning for South African estate duty, an additional layer of complexity emerges once your wealth crosses borders. This is because many countries tax assets based on where they are located, not where the owner resides.

This is where situs tax enters the picture.

 

What exactly is situs tax?

Situs tax is an umbrella term used to describe estate, inheritance or succession taxes imposed because an asset is considered to be located within a particular country. The owner's country of residence may be completely irrelevant.

For example:

  • Shares in a US-listed company are often regarded as US situs assets.
  • Property located in the UK is generally subject to UK inheritance tax rules.
  • Certain Irish assets may be subject to Irish Capital Acquisitions Tax.
  • Assets situated in France may be exposed to French succession taxes.

The important point is this: you do not need to live in a country to have exposure to its death taxes. A South African investor holding US shares through an offshore portfolio could potentially have US estate tax exposure despite never having set foot there.

 

Final thoughts – asking the right questions

Offshore investing can be an excellent way to build and diversify wealth, but investment returns should not be the only consideration. When investing internationally, you should ask not only:

"What return can I expect?"

but also:

"What happens to this asset when I am no longer here?"

Understanding the answer can make a significant difference to the wealth ultimately passed on to your future generations. After all, death and taxes may both be inevitable - but with proper planning, at least one of them doesn't have to come as a surprise.
