With the 2026 tax filing season underway, South African expatriates should take note that they may still be required to submit annual tax returns to the South African Revenue Service (SARS), even after years of living and working abroad.

Many expatriates assume that relocating overseas automatically removes them from the South African tax system, but this is often not the case.
Whether an expatriate is required, under Section 25 of the Tax Administration Act, 2011 (Act No. 28 of 2011), to submit a return depends on a range of factors. These include their tax residency status, the nature and source of their income, and whether they continue to hold financial interests in South Africa.
As SARS continues to strengthen its compliance capabilities and increase visibility over offshore structures and international income, expatriates should take the opportunity to review their filing obligations and ensure they understand whether they are required to submit a return. Failing to meet a filing obligation can result in penalties and interest accruing quickly.
Why Leaving South Africa Does Not Always End Your Tax Filing Obligations
Physical relocation abroad does not, in itself, bring an end to a taxpayer’s relationship with SARS. The key consideration is whether the individual has formally ceased South African tax residency. Where this has not occurred, SARS may still regard the person as a South African tax resident, which can result in ongoing reporting obligations on worldwide income and assets.
Foreign Income and Offshore Assets Remain Important
For expatriates who are still South African tax residents on SARS’ records, offshore income and foreign assets remain highly relevant from a tax compliance perspective.
This may include:
Where foreign assets exceed prescribed thresholds, or where offshore income is attributed under South African tax legislation, SARS may still require detailed disclosure in an annual tax return.
Controlled Foreign Company (CFC) rules can also create additional complexity. South African expatriates who retain ownership interests in offshore companies may find they are still subject to reporting requirements and, in some cases, tax implications in South Africa.
Income Thresholds Are Not a Blanket Exemption
While SARS does provide certain income thresholds below which individuals may not need to file, expatriates often misunderstand these exemptions.
For the 2026 filing period, individuals under 65 generally fall within the filing threshold once gross income exceeds R95 750. The thresholds increase to R148 217 for taxpayers aged 65 to 74, and R165 689 for those aged 75 and older.
However, these thresholds apply only in limited circumstances and do not override other filing triggers.
If an expatriate receives foreign income, earns rental income, disposes of South African assets, carries on trade, or retains specific offshore structures, a return may still be required regardless of income level.
Formalising Non-Tax Residency Does Not Mean Closing Your SARS File
Even where an individual has formally ceased South African tax residency, filing obligations do not necessarily disappear entirely.
Non-residents may have to file South African tax returns where they:
This is particularly important for expatriates who believe that financial emigration or non-resident status completely removes them from the South African tax system. While it may reduce exposure, it does not automatically eliminate compliance obligations.
Too many South Africans abroad only discover unresolved tax obligations years later when attempting to access retirement funds, regularise their tax affairs, transfer capital offshore, finalise non-resident tax status and respond to SARS verification requests.
By this stage, administrative complications, penalties, and compliance risks may already have escalated significantly.
Auto-assessments Can Create False Confidence
Some expatriates may receive a SARS auto-assessment and assume no further action is required. While SARS may issue these assessments where sufficient third-party data is available, offshore income and international assets are not always fully captured in its records.
This poses a significant risk for individuals with foreign employment income, offshore investments, international pension structures, foreign bank accounts, or overseas business interests. Despite the auto-assessment system, the responsibility remains with the taxpayer to ensure that all relevant disclosures are complete and accurate.
Do Not Overlook SARS Filing Deadlines
Where a filing obligation exists, expatriates remain subject to standard SARS submission deadlines.
For the 2026 filing season:
These timelines can become particularly challenging for expatriates who are simultaneously managing tax obligations across multiple jurisdictions.
No Skeletons Left in the Closet
For South African expatriates, the key takeaway is clear: physically leaving South Africa does not automatically terminate SARS filing obligations.
With guidance from cross-border tax specialists, expatriates can obtain a proper review of tax residency status, income streams, offshore assets, and ongoing South African financial ties to ensure compliance and avoid unexpected exposure in the future.
