Freelancer Income Tax Calculator Guide
A planning guide for estimating freelancer taxable income before using South African income tax tables or provisional tax estimates.
Last updated: 19 May 2026
What to calculate first
For freelancers, the first calculation is usually taxable profit, not gross client income. Start with total freelance income, subtract supported business expenses, then check retirement contributions, medical credits, rebates, PAYE already withheld and provisional payments where relevant.
Freelancer estimate worksheet
| Line | What to enter | Record to keep |
|---|---|---|
| Gross freelance income | Client and platform income for the tax year | Invoices, statements, bank records |
| Business expenses | Supported expenses linked to earning income | Invoices, receipts, calculations |
| Estimated taxable profit | Income less supported expenses before personal tax items | Working paper |
| Tax table check | Apply the correct SARS tax year table and rebates | SARS tax table source |
| Payments already made | PAYE, provisional tax or credits already available | IRP6, IRP5, assessments |
Use the correct tax year
SARS tax tables change by tax year. For the 2027 tax year, SARS published rates for 1 March 2026 to 28 February 2027. Do not use those tables for a historic tax year or a future year until SARS has published the relevant figures.
Why this is only an estimate
A final SARS assessment can differ because of medical credits, retirement limits, assessed losses, penalties, interest, disallowed expenses, foreign income, PAYE credits or provisional tax payments. Treat any calculator number as planning guidance.
Common freelancer mistakes
- Estimating tax from gross income instead of taxable profit.
- Forgetting that business expenses need records.
- Mixing tax years when invoices are paid late.
- Ignoring provisional tax timing.
- Assuming a calculator replaces an IRP6 calculation.
