How this service works
South African reference data as clean, cited JSON: fuel prices, interest rates, FX and bond yields, tax tables, tariffs, wages and grants, live government tenders and crypto prices, plus calculators. Built for AI agents and applications.
Output
A JSON object containing the computed South African personal income tax breakdown including gross tax before rebates, applicable primary/secondary/tertiary rebates based on age, medical scheme fees credit based on membership counts, and the final net tax payable amount — all based on current SARS tax tables and thresholds.
Example use cases
Employee take-home pay estimate
“I earn R420,000 a year in South Africa and I'm 32 years old with no medical aid. How much income tax will SARS take and what's my effective tax rate?”
Retirement planning tax impact
“My dad is 67 and earns R980,000 a year from his pension in South Africa. Can you calculate his income tax liability including the senior rebate?”
Medical aid credit benefit calculation
“Calculate the South African income tax for someone earning R1,100,000 annually, aged 40, with 4 medical scheme members including the taxpayer and 2 additional dependants — I want to see how much the medical credits reduce the tax bill.”

Choose this endpoint when you need accurate, up-to-date South African personal income tax calculations including age-based rebates and medical scheme fees credits, sourced from current SARS tables. It is purpose-built for South African tax law and will be more accurate than generic tax estimators or LLM knowledge for ZAR-denominated South African tax computations.
