A tax refund is your own money coming back after an interest-free loan to SARS. If you get a large one every year, it means your PAYE or provisional tax estimate is wrong, not that you had a good year.
A negative balance on eFiling feels like a windfall, but that money was always yours. Receiving it back means SARS held your working capital for twelve to eighteen months while you paid interest on overdrafts, or missed opportunities to reinvest, elsewhere in the business. In a high-inflation environment, cash flow is oxygen, and letting SARS sit on yours restricts your operational agility for no good reason.
Most registered businesses and directors are provisional taxpayers, submitting an IRP6 return twice a year based on estimated taxable income. The Income Tax Act allows you to base your first estimate on your historical "basic amount," and out of fear of the 20% underestimation penalty, many businesses simply apply a standard inflation bump to that figure regardless of actual trading conditions. Avoiding the penalty matters, but defaulting to an inflated estimate every time means meeting compliance at the cost of your own liquidity, which was never the intention of the system.
A consistent annual refund is really a symptom of stale data driving your estimate. If your bookkeeping is reconciled monthly against live bank feeds through Xero or Sage, your mid-year and year-end IRP6 figures can be based on actual year-to-date performance instead of last year's number with a guess bolted on.
Say you overpay by R200,000 across the year. That capital could have funded bulk inventory at a discount, a targeted marketing push, or simply sat in an access bond offsetting interest. If your business runs an overdraft at prime plus 2%, roughly 13.75%, lending that R200,000 to SARS for free costs you around R27,500 in interest you're still paying elsewhere. That's money leaving your business twice over one overpayment.
Stop defaulting to the basic amount. Project your current year's taxable income from actual year-to-date figures, not historical data plus inflation.
Reconcile monthly. Accurate, current bookkeeping is what makes a precise IRP6 estimate possible.
Factor in capital allowances immediately. Section 12B renewable energy deductions and similar allowances should reduce your estimate as soon as they apply, not wait for your final return.
Review director remuneration structure. Over-deducted PAYE on monthly drawings is a common, quietly compounding overpayment.
Not really. A large, consistent refund means you overpaid, effectively lending SARS your working capital interest-free for months at a time.
Up to 20% if your estimate falls materially short of your actual liability, which is why many businesses overcorrect in the other direction.
If your refund or balance owing is consistently small relative to your total tax liability, your estimate is well-calibrated. Large swings either way signal a process gap.
Aim for a final assessment as close to zero as legally possible, not a large refund. That balance is the real sign of an accurate, well-managed tax position. For more on cash flow strategy, see our blog.
