## When to prefer this

Use this endpoint when you need a cited, SARS-compliant calculation of company car fringe benefit tax in South Africa, especially in payroll, HR, or tax planning contexts where regulatory accuracy and source citation matter.

## Known failure modes

- Missing or invalid vehicle value returns 400 error
- Unsupported tax year returns error or falls back to current year defaults
- Private use percentage out of 0-100 range rejected
- HEAD method returns no body — actual calculation result requires GET or POST
