Your Final SA Tax Return: How the Split Year Works

In the year you leave South Africa, the tax calculation breaks into two pieces — one period while you were tax-resident in SA, one after you'd left. SARS does not ignore the months you were gone; it taxes each period by the rules that applied to you at the time. If you earned income in both periods, you file one tax return, but the return contains two separate income calculations and two sets of tax liabilities. This is your final SA tax return and the split year it has to straddle — and it's where most emigrants find their tax complexity actually lives.

When you stop being a South African tax resident

Tax residency and immigration residency are separate concepts. You can hold a South African ID and still be a non-resident for tax purposes; you can hold a work permit in Canada and still be a tax resident of SA while you plan your final departure. SARS defines a resident as someone who has permanent accommodation in SA and carries on business or maintains a centre of vital interests there.

The practical calendar: if you leave SA on July 15, you are resident from January 1 to July 14 (195 days). From July 15 to December 31 (169 days) you are non-resident. Your income for the 195 resident days is taxed under SA resident rules. Your income for the 169 non-resident days is taxed under non-resident rules.

What changes for the non-resident period

Resident income (January 1–July 14 in this example): You pay tax on worldwide income — SA employment, rental income, investment income, remittances from Canada, everything.

Non-resident income (July 15–December 31): You pay tax only on SA-source income. Income earned in Canada (a Canadian employment contract, Canadian freelance work, Canadian investment income) is not taxable to SARS once you've left. You owe Canadian tax on it instead.

That split is where the benefit lives: if you left in July and worked remotely for a Canadian company earning CAD in August, September, October, November and December, SARS does not tax that income. Only SA-source income (rental income from property still renting in SA, directors' fees from SA companies) is taxable in the non-resident period.

The practicality: provisional tax

If you're still earning SA-source income in the non-resident period (or earning income during the resident period that you know will be significant), SARS requires provisional tax payments. Provisional tax is a quarterly payment based on an estimated tax liability for the year. If you change your residence mid-year, you need to contact SARS and adjust your provisional tax estimate — or you face a bill at year-end.

Most practitioners handle this: notify SARS of your change of status and adjust quarterly payments downward because your annualised income will be lower (half a year's employment is half the annual income for assessment purposes).

Filing the return

Your final SA return is a single document filed in the tax year after you left (so if you left mid-2026, you file the 2026/27 return by the 2027 deadline). The return shows:

• Resident-period income and tax calculation
• Non-resident period income and tax calculation
• Any provisional tax paid across the year
• Net tax owing or refund due

The return itself is structured the same way as any other annual return; the split is reflected in how the income lines are grouped and where tax rates are applied. A South African tax practitioner knows this template and does it routinely.

The money side: when to pay

The provisional-tax payments you made during the year are credited against your final liability. If you overpaid (common, because you guessed high), you get a refund. If you underpaid, you owe the difference. Most refunds land in your bank account in the first month after filing if the return is uncomplicated.

What South Africans often get wrong

One: thinking a person who left in July has zero tax for the year. Not true — the January-to-July period is fully taxable at resident rates.

Two: thinking SA-source income in the non-resident period is tax-free. Not true — it's still taxed, just under different rules (lower rates, sometimes).

Three: not notifying SARS of the change of status. If SARS keeps assessing you as a full-year resident and you get a bill four years later, it's your responsibility to explain and correct it.

What to do if you're leaving

Start the process with a South African tax practitioner or CPA six to eight weeks before your departure date. Give them your expected departure date and any income scheduled to land after that date. They'll calculate your provisional tax adjustment and stay on retainer to file your final return in the filing season after the tax year ends. The cost is typically R2,000–R5,000 ZAR depending on the complication of your tax affairs.

Don't leave the country assuming "I'll sort it out later" — non-compliance racks up penalties, and you're likely to stay in the SA tax system for years after departure if you don't close it formally.
