Yes. Every calculator on this page is free, with no limit on how many times you can use them. The calculators themselves cost nothing. You only pay if you choose TaxTim to help you complete and submit your actual tax return to SARS.
No. You can open any calculator and run your numbers immediately without creating an account, logging in or sharing personal details. Registration is only needed when you're ready to prepare and file your real tax return with TaxTim's step-by-step help.
By default they use the most recent South African tax year. The 2026 year of assessment runs 1 March 2025 to 28 February 2026. Most calculators include a tax-year selector so you can also calculate for the current 2027 year or earlier years using the correct SARS rates for that year.
They use the official SARS rates, rebates and thresholds and have been refined over many years, so they give a reliable estimate. Results are an estimate for planning, not a SARS assessment. Your final figure depends on every detail on your return, which TaxTim confirms when you actually file.
If you earn a salary, start with the Income Tax (Salary) calculator to see your PAYE and take-home pay, then the Tax Refund calculator to estimate what SARS owes you. From there, add the specific calculators that match your situation, such as travel, medical, home office or retirement.
Run the numbers, then let TaxTim walk you through filing and submit your return to SARS.
