Filing season is almost here, and for most South Africans it is a moment they either ignore or dread. But if you have moved money offshore, hold foreign assets, or earn any income in a foreign currency, it is worth pausing before you accept an auto assessment or submit a return. Not because the process is complicated, but because a small amount of preparation now can save a great deal of confusion later.
SARS has confirmed the dates for the 2026 filing season. Auto assessments will run from 1 to 12 July, with the filing window for non-provisional individual taxpayers opening on 13 July. That gives anyone with offshore financial activity roughly three weeks to get their records in order.
Why offshore exposure is more common than people think
Offshore financial exposure does not mean a sprawling international portfolio. For many South Africans, it is simply the result of using the Single Discretionary Allowance to move savings abroad, holding a foreign currency account, owning global shares through a platform, receiving foreign investment income, or earning professional or business income from overseas clients. If any of these apply to you, your tax return may need to reflect more than just your local salary.
The challenge is that offshore financial activity tends to be scattered. Unlike local income, which arrives in standardised formats like IRP5s, foreign income comes from multiple institutions across different countries and currencies. Statements arrive in different formats, reporting periods vary, and it is easy to lose track of a dividend payment or a foreign interest accrual from earlier in the year. By the time filing season opens, piecing together twelve months of global activity under time pressure is where most mistakes happen.
The R250 000 threshold: when offshore assets may trigger a filing obligation
According to SARS Notice No. 7422 for the 2026 filing season, any South African resident who held foreign currency or owned assets outside South Africa with a total value exceeding R250 000 at any point during the year of assessment is required to submit an Income Tax Return (ITR12). This applies regardless of whether you used your allowances legitimately and regardless of whether SARS selects you for an auto assessment.
Tax practitioners note that this threshold is one of several grounds that can trigger a mandatory filing obligation. Others include making capital gains above R40 000, having income or gains attributable to foreign funds, or holding participation rights in a controlled foreign company. If you are unsure whether any of these apply to your situation, this is the moment to check with a registered tax practitioner rather than assume your position is straightforward.
What your SDA activity means for your return
Using the Single Discretionary Allowance is routine and entirely manageable. Under the 2026 exchange-control updates, South African residents aged 18 and older can transfer up to R2 million abroad each calendar year without obtaining prior SARS approval. No tax clearance certificate is required, and the process goes through an authorised dealer as normal.
The transfer itself is not the issue. What matters is what happened to those funds once they were offshore. The mistake many people make is treating the offshore transfer as the end of the process. In reality, it is the start of a record that needs to remain clear for banking, exchange-control and tax purposes. If the money was invested and generated returns, including interest, dividends and capital growth, those returns may need to be reflected on your tax return.
Filing season is a useful prompt to revisit those investments, check how they performed during the year of assessment, and confirm that your records are complete enough to support accurate disclosure. The initial transfer is often only the beginning of the story.
Offshore investment income: interest, dividends and capital gains
In plain terms: if your offshore investments earned anything during the year of assessment, those earnings may form part of your taxable income. Interest accrued in a foreign bank account, dividends paid by international companies, and gains realised from selling offshore assets are all categories that tax practitioners advise reviewing carefully before submitting a return. The fact that these amounts were earned abroad and paid in a foreign currency does not exempt them from South African tax obligations.
International institutions do not report through a single South African framework, which means the responsibility for locating and consolidating this information falls on the individual. Annual investment statements, transaction histories, and bank records from offshore institutions are the foundation. Gathering these before the filing window opens, rather than scrambling for them during it, is the single most effective thing you can do to make filing season manageable. If the tax implications of any of these income types are unclear, a qualified tax practitioner is the right person to consult.
The most common mistakes and how to avoid them
The errors that generate SARS queries are rarely the result of deliberate avoidance. They are almost always the result of incomplete records: an offshore account that was overlooked, an annual statement that was never downloaded, a dividend payment that fell through the cracks early in the year. The fix is not complicated, but it does require acting before the deadline pressure sets in.
A practical approach is to treat the weeks before filing season opens as a records audit. Work through your international financial activity for the year: every account, every platform, every transfer. Identify any gaps and request missing documentation from your bank or investment provider while there is still time to receive it. Equally important is not accepting an auto assessment without first confirming it reflects your full position. SARS works from the information available to it, and offshore income or assets it is not aware of will not appear in an auto-generated assessment.
The weeks before filing season are an opportunity to step back and check whether your offshore position is clear. Where did the money go? What did it earn? What was sold? What still needs to be verified? For globally minded South Africans, these are not last-minute admin questions. They are part of managing offshore wealth properly. The investment decision matters, but so does the paper trail that supports it.
