The formula has never asked what the house is worth. It asks what you earn — remuneration proxy in, phantom rent out. Two colleagues in identical houses pay different tax.
Where the employer rents the home from an unconnected landlord, the benefit may be the employer's actual cost if lower than the formula — reality gets a veto over the fiction.
B tracks the primary tax threshold: R99 000 for the 2027 year (up from R95 750). Below-threshold earners generate no phantom rent at all.
Free or cheap housing from an employer is taxed as if the employee received rent — but the "rent" is manufactured by formula: (A − B) × C/100 × D/12. A is the remuneration proxy (broadly, last year's remuneration), B an abatement tied to the tax threshold, C a quality dial of 17–19, D the months of use. The property's market value appears nowhere.
Inbound expatriate away from their usual residence outside the Republic: no taxable value for the first 24 months, provided the accommodation does not exceed R25 000 per month (and the employee was not in SA for more than 90 days in the preceding year). Month 25 — the formula wakes up.
Accommodation while the employee is away from their usual residence for work — the site camp, the audit-week hotel — carries no value. It is the employer's cost of doing business, not the employee's enrichment.
Inbound secondees: 24 months, R25 000/month ceiling, conditions attached. A generous runway — with a cliff edge. Diarise month 25 before payroll discovers it for you.
The para 9 formula prices residential accommodation. The company beach house for a week is valued at the employer's cost (if rented) or the prevailing daily rate — often far harsher than the formula.
