Moving Abroad? Why Ignoring Your SARS Tax Residency Status Could Cost You Dearly

Packing up your life and moving overseas is an exciting milestone. Whether you’re chasing career opportunities in Europe, relocating your family to Australia, or setting up a new lifestyle in the UK, your focus is naturally on visas, flights, and finding a new place to live.

However, there is one critical item that many South African expats unintentionally leave off their moving checklist: formally declaring the cessation of their South African tax residency with SARS.

A common myth among South Africans living abroad is that physical absence equals tax freedom. Many assume that once they board a flight out of O.R. Tambo or Cape Town International, SARS automatically stops tracking their earnings.

The reality? Moving abroad does not automatically switch off your South African tax obligations.

Unless you formally declare that you have ceased to be a South African tax resident, SARS still considers you a resident for tax purposes. That means you could remain liable for tax on your worldwide income, long after you’ve settled into your new life overseas.

At GAS Accounting, we regularly help South African expats navigate financial immigration and tax residency, ensuring a clean, fully compliant exit from the SARS tax net. Here is what you need to know about formalising your status before SARS comes knocking.

1. Physical Relocation vs. Tax Residency: Knowing the Difference

South Africa operates on a resident-based tax system. This means tax residents are taxed on their global earnings, regardless of where the money was earned or paid. Non-residents, on the other hand, are taxed only on South African-sourced income (such as local rental properties or local business profits).

To determine whether you are a resident, SARS relies on two key tests:

The Ordinarily Resident Test: This looks at where your true, intentional home is, considering factors like where your immediate family lives, where your primary assets are held, and where you intend to return.
The Physical Presence Test: If the first test is inconclusive, SARS applies a strict, multi-year day-count formula based on your physical time spent inside South African borders.

Simply living abroad, even for years, does not automatically make you a non-resident in SARS’s eyes. Until you formally log a Declaration of Cease to be a Tax Resident with SARS and receive official confirmation, your worldwide income remains theoretically exposed to South African tax.

2. SARS is Cross-Referencing Data: Unformalised Status is a Growing Liability

If you quietly stopped filing SARS tax returns after moving overseas, you are sitting on a growing tax liability.

Since March 2021, SARS has required a formal, documented cessation process. Furthermore, SARS now actively cross-references:

International travel data and border records
Foreign bank account data (via international exchange-of-information agreements)
Third-party financial records

If SARS flags you during a routine audit years down the line, attempting to retroactively reconstruct records to prove when your residency ended can lead to severe penalties, interest charges, and costly legal disputes. Formalising your non-resident status creates a clear, dated paper trail that protects you from future liability.

3. Demystifying the Section 9H Exit Tax

One of the main reasons expats delay formalising their tax residency is fear of the Section 9H “Exit Tax.”

When you cease tax residency, SARS deems that you have “disposed” of most of your worldwide assets at fair market value on the day immediately before your residency ends. This triggers a Capital Gains Tax (CGT) event.

However, many expats overestimate what is actually taxed. Key assets excluded from Section 9H Exit Tax include:

South African immovable property (e.g., your family home or local investment properties)
Retirement fund interests (Pension, Provident, or Preservation funds and Retirement Annuities)
Personal-use assets (such as personal vehicles or household furniture)
Cash holdings

Knowing exactly what falls in and out of scope is the difference between a manageable, well-planned tax event and an unpleasant surprise. At GAS Accounting, we calculate your actual Section 9H exposure before you commit to a departure date, allowing you to plan with total certainty.

4. The 3-Year Retirement Annuity Lock-In Rule

If you hold a South African Retirement Annuity (RA) or preservation fund, planning your exit early is essential.

Under current legislation, once you cease tax residency, you cannot access your retirement fund as a lump sum until three consecutive years have passed since SARS formally confirmed your non-resident status.

Because the three-year clock only starts ticking after SARS confirms your non-resident status, delaying your SARS declaration directly delays your ability to unlock and transfer your retirement savings abroad.

5. Critical 2026 Budget Update: Phased Departures for Married Couples

If you are planning a staggered move as a couple, where one spouse moves ahead while the other remains in South Africa temporarily, be aware of recent tax changes.

Historically, couples used the inter-spousal donation exemption to transfer assets tax-free to the departing spouse before leaving. Following the 2026 Budget, the spousal donations tax exemption now only applies while the receiving spouse remains a South African tax resident.

If you are planning a phased move, this update changes the sequencing of asset transfers and residency declarations. Structuring this correctly requires proactive tax advice before either spouse departs.

6. What Happens If You Ever Decide to Return?

Life changes, and many expats eventually choose to move back home. From July 2025, SARS requires returning individuals to formally notify them to reinstate South African tax residency.

When you return:

You resume being taxed on worldwide income from your reinstatement date.
Your asset cost base for Capital Gains Tax resets to the market value on your return date.
If you haven’t completed your 3-year retirement lock-in period while abroad, the clock resets to zero.
