Tax residency in South Africa explained

Your South African tax residency status determines how SARS will tax you.

South Africa follows a residence-based system:

  • Tax residents are taxed on their worldwide income
  • Non-residents are taxed only on South African-sourced income

SARS uses two primary tests to determine tax residency in South Africa:

Ordinarily Resident test

  • Applies if South Africa is your main home
  • Includes your intention to return and remain here

Physical Presence test

  • Based on the number of days you spend in South Africa over a set period

Establishing your status correctly from the outset is essential, and this is where using an experienced tax practitioner in South Africa adds real value.

How South Africa tax applies to your income

Once you re-establish tax residency in South Africa, South Africa rules means that you will be taxed on your worldwide income, not just what you earn locally.

This often catches returning or new residents off guard, particularly if you:

  • Continue working for a foreign employer
  • Earn rental income from overseas property
  • Hold offshore investments or receive dividends
  • Earn interest from foreign accounts

Double taxation agreements: Protecting you from paying twice

South Africa has double taxation agreements (DTAs) with many countries

These agreements:

  • Determine which country has the primary taxing rights
  • Ensure relief is available for foreign taxes correctly paid abroad
  • Apply to income such as salaries, pensions, interest and dividends

Foreign investments: What changes when you return

Many offshore “tax-free” investments, such as UK ISAs, lose their tax-free status in South Africa.

This means:

  • Income and capital gains may become taxable
  • Your investment strategy may need to be reviewed

Planning ahead allows you to restructure where necessary and avoid unnecessary tax costs.

Overseas assets and Capital Gains Tax

When you resume tax residency in South Africa, your global assets are rebased for tax purposes.

  • Assets are valued at market value on your return date
  • This becomes your base cost for future Capital Gains tax

For example, if you own property abroad, any future capital gain will be calculated from its value when you became a tax resident again.

It’s a good idea to obtain formal valuations before or at the time of your return to ensure accurate reporting later.

Retirement and pension planning

If you’ve built up retirement savings overseas, these need careful review before and after your return.

  • Certain foreign pensions may qualify for favourable tax treatment in South Africa
  • Double taxation agreements often allocate taxing rights to your country of residence

With the right planning, this can result in meaningful tax efficiencies and improved long-term outcomes.

Key steps for managing your tax re-entry into South Africa

SARS currently has a relatively simple system for tax immigration. However, this may change as more individuals return to South Africa and SARS refines the information it requires to assess tax residency correctly.

We recommend focusing on the following key steps:

  • Obtain confirmation of foreign tax residence before leaving the country where you are currently living
  • Maintain clear records of your tax residency position in South Africa, including which test applies (ordinarily resident or physical presence) and why
  • List all your assets on your tax immigration date , together with supporting evidence such as valuations or statements
  • Ring-fence legitimate offshore assets where appropriate , particularly if you are considering estate planning opportunities. An experienced estate planner can assist here
  • Take screenshots of your RAV01 profile showing your non-resident status from your date of exit, as well as confirmation of when you become a South African tax resident again

Frequently asked questions

1. When do I become a tax resident in South Africa again?

You become a tax resident when you meet either the Ordinarily Resident test or the Physical Presence test. In many cases, this depends on your intention to live in South Africa permanently or the number of days you spend in the country. Getting the timing right is important, as it affects when your worldwide income becomes taxable.

2. Will I pay tax in South Africa on income earned overseas?

Yes, once you are a tax resident, SARS may tax your worldwide income. This includes foreign employment income, rental income, interest and dividends. However, DTA’s ensure that foreign taxes correctly paid are available for relief in the country of tax residency.

3. Do I need to inform SARS when I return to South Africa?

Yes. Your tax residency status should be updated with SARS, typically via your RAV01 profile. This ensures your records are accurate and helps avoid issues with incorrect tax treatment or effective dates.

4. What happens to my offshore investments when I return?

Many offshore investments that were tax-free abroad may become taxable in South Africa. Income and capital gains could be subject to South African tax, so it’s important to review your investment structure before and after your return

5. Should I speak to a tax practitioner before moving back?

Yes. Working with a tax practitioner in South Africa helps you correctly establish your tax residency, structure your global income and assets efficiently, and ensure full compliance with SARS. This can prevent costly mistakes and give you clarity before you move.

6. What is the physical presence test in South Africa?

The physical presence test determines whether SARS considers you a tax resident based on the time you spend in South Africa. You must answer “yes” to all three of the following:

  • Do I spend more than 91 days in South Africa in the current tax year?
  • Have I spent more than 91 days in South Africa in each of the past five tax years?
  • Have I spent more than 915 days in total in South Africa over the past five years?
