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 the calculated South African lump sum tax amount based on the SARS tiered tax table, factoring in the lump sum type (retirement, retrenchment, etc.), the gross amount, and any prior lump sums received that affect which tax bracket applies to the current withdrawal.
Example use cases
Retirement withdrawal tax estimate
“I'm about to retire and want to withdraw R2,000,000 from my pension fund — how much South African tax will I owe on that lump sum, assuming I've never taken a lump sum before?”
Retrenchment severance tax check
“I was just retrenched and I'm getting a R450,000 severance payout. What is the SARS lump sum tax on a retrenchment type payment of R450,000 with no previous lump sums?”
Second withdrawal after prior lump sum
“I took a R200,000 provident fund withdrawal two years ago and now I want to withdraw another R800,000 — what's the tax on this second lump sum given my R200,000 previous withdrawal?”
Technical details
Endpoint
HEADhttps://zaref.dev/calc/lump-sum-tax?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a South African-specific lump sum tax calculation that correctly applies SARS tiered tax tables and accounts for cumulative prior lump sums, rather than attempting to approximate using a generic tax or income calculator. Especially valuable when advising on retirement, retrenchment, or provident fund withdrawal decisions.
Side effects
- Missing required 'amount' parameter returns an error
- Invalid or unsupported 'type' enum value returns a validation error
- Non-numeric amount string causes a parsing error
- Negative or zero amount may return an error or zero tax result
- HEAD method returns no response body — metadata only; use GET for the actual computed result
