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
Returns calculated provisional tax figures for a South African taxpayer including estimated tax liability and net provisional tax payable after accounting for employees tax already paid, based on SARS tax tables and the provided income, age, and withholding inputs
Example use cases
Freelancer provisional tax estimate
“I'm a 42-year-old freelancer in South Africa with annual taxable income of R600,000 and no employees tax withheld — what's my provisional tax liability?”
Self-employed with partial PAYE offset
“My annual taxable income is R1,200,000 and my employer already deducted R180,000 in employees tax. I'm 55 years old — how much provisional tax do I still owe SARS?”
Young contractor first provisional payment
“I'm 28 years old and just started contracting — my taxable income this year will be about R450,000 and I haven't paid any employees tax. Can you calculate my South African provisional tax amount?”
Technical details
Endpoint
HEADhttps://zaref.dev/calc/provisional-tax?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cited, AI-agent-friendly computation of South African provisional tax liability using SARS-aligned tax tables, especially when you already have the taxpayer's annual taxable income, employees tax paid, and age. Prefer this over generic tax calculators when the user is a South African provisional taxpayer (freelancer, contractor, director, or investor) who needs SARS-specific figures without building the calculation from scratch.
Side effects
- Missing required query parameters (annual_taxable_income, employees_tax_paid, or age) returning 400 Bad Request
- Invalid or non-numeric parameter values causing computation errors
- HEAD method response contains no body — metadata/headers only, actual computed values may not be in body
- Tax tables may be outdated if SARS updates rates between API refreshes
