What This Calculator Estimates
This tool estimates South African income tax based on the income and rate you enter. SARS applies a progressive bracket system where the marginal rate increases as taxable income rises, and brackets, rebates, and thresholds are typically adjusted each year in the national Budget Speech. Because those figures change annually, the calculator keeps the rate field editable so you can plug in the bracket relevant to your income level and get a current estimate rather than relying on a number from a prior tax year.
How to Use This Calculator
- Enter annual income.

Tips for a More Accurate Estimate
- Use your IRP5 or payslip to sanity-check this estimate, since SARS applies exact published brackets through payroll.
- Age-based rebates (primary, secondary, tertiary) reduce actual tax owed but aren't applied automatically here.
- Provisional taxpayers should note their filing process differs from standard PAYE reconciliation.
- SARS updates its tax tables annually, typically after the February Budget Speech — recheck rates each tax year.
- This is a planning tool; your eFiling submission is what determines your official tax position.
Frequently Asked Questions
How is this different from the PAYE calculator?
This is framed as a general income tax estimate, while the PAYE calculator focuses on monthly employment withholding specifically — both work the same way under the hood.
Does South Africa tax worldwide income for residents?
South African tax residents are generally taxed on worldwide income, subject to specific exemptions and foreign tax credit rules, so check SARS guidance if you have foreign income.
What are tax brackets vs rebates?
Brackets determine the marginal rate applied to each slice of income, while rebates are fixed amounts subtracted from the tax calculated, effectively creating a tax-free threshold. This calculator only handles the bracket/rate side.
Can this be used for provisional taxpayers?
You can enter any income figure, but provisional taxpayers (like freelancers or business owners) file under a different process than salaried PAYE, so treat this as a rough planning estimate.
How often do SARS tax tables change?
Typically once a year, following the national Budget Speech, though mid-year adjustments have happened. Always check SARS's official site for the current tax year's tables.
