Why SARS owes you a refund (and how to get it)

How PAYE over-withholding happens

Your employer deducts PAYE every month as if that month's salary, annualised, is what you will earn all year. Real life is lumpier than that, and the mismatches all lean the same way - toward SARS holding too much of your money:

• Bonus months. A thirteenth cheque or performance bonus can push that month's deduction to a rate far above your true annual rate. The excess only unwinds at assessment.
• Job changes and gaps. Work seven months of the tax year and each employer withheld as if you earned that salary for twelve. Unemployed months drag your actual annual income - and your correct tax - down.
• Medical aid paid personally. If you pay your own medical scheme contributions rather than through payroll, the medical tax credits are often not reflected in your monthly PAYE at all. They only come back when you file.
• Retirement annuity contributions. RA contributions paid from your own bank account are deductible within the legal limits, but your employer does not know about them, so PAYE ignores them all year.

The auto-assessment trap

Each filing season SARS auto-assesses millions of taxpayers using the data it already has: IRP5s from employers, medical scheme certificates, retirement fund certificates, investment income. If the third-party data is complete, the auto-assessment is fine and any refund is paid out automatically. The trap is what SARS cannot see: an RA you pay privately where the certificate did not reach them, out-of-pocket medical expenses, home office or travel claims, a side income with deductible expenses. Accepting an auto-assessment that is missing deductions means accepting a smaller refund than you are owed. You are allowed to reject it and file a full return instead - check the figures before the window closes for that season.

How long the refund takes

When a return is assessed with a refund due and nothing is flagged, SARS generally pays out within a few business days - its published service standard is around 72 hours for straightforward cases. If your return is selected for verification or audit, the clock stops until you upload the supporting documents and SARS finalises the review, which can take weeks. The fastest refunds belong to people whose paperwork is ready before they file: medical certificates, RA certificates, and logbooks if you claim travel.

Common refund blockers

• Outstanding returns. SARS does not pay a refund while any prior year's return is outstanding. One missing old return can freeze a current refund indefinitely - filing the old year is usually the whole fix.
• Banking details verification. If your bank details are new, changed, or fail SARS's checks, the refund is held until they are verified. Keep one account on record and update it through eFiling before filing season, not after the refund is stuck.
• Verification and audit. A flagged return waits for documents. Respond to the letter quickly with everything requested - partial uploads restart the wait.
• Other tax debts. If you owe SARS on another account or year, the refund is set off against that debt first and only the balance, if any, is paid out.

How to actually get it

Register on eFiling if you have not, make sure every prior year is filed, gather your certificates, and either accept a correct auto-assessment or file a full return with your deductions included. Then leave the banking details alone and respond fast to any verification letter.
