Work out what to set aside for SARS as a sole proprietor.
Estimates your SARS income tax for the 2026/27 tax year using brackets, age rebates, medical credits and the s11F retirement deduction - and splits it across the two IRP6 provisional payments.
Sound familiar?
- “You don't know how much of each invoice to leave in the tax account.”
- “Your IRP6 first-payment date is coming up and you have no idea what the figure should be.”
- “Your accountant only shows you the bill at year end and it's always a shock.”
What this tool does
Takes your estimated net business profit, applies the SARS sliding brackets, deducts age-based rebates and annual medical scheme fees tax credits, and shows what to set aside. It also splits the annual tax into the two IRP6 provisional payments due end of August and end of February.
Extra rebates apply at 65 and 75.
You + dependants on the scheme.
s11F: capped at 27.5% of income.
What the law actually says
- •Income Tax Act 58 of 1962 sets the marginal brackets and rebates that SARS publishes each year.
- •Section 11F caps the deductible retirement-fund contribution at 27.5% of the greater of remuneration or taxable income, up to an annual rand cap.
- •Provisional tax (IRP6) under the Fourth Schedule requires two payments per year of assessment. Underestimating the second estimate below the statutory tolerance triggers the paragraph 20 underestimation penalty.
