What the scheme is for
The Workers' Compensation Fund Control Board runs a statutory insurance scheme covering workers injured, disabled or killed in the course of employment, and dependants of workers who die at work. The fund pays the compensation; employers pay into the fund through an annual assessment.
The practical consequence for an employer is that a covered workplace injury does not become a direct liability on your business, provided you are registered and up to date.
Who has to register
Every employer. There is no small-business exemption, and the obligation explicitly extends to households employing domestic workers such as a driver, a housekeeper or a gardener. If you employ anyone in Zambia, you are within scope.
How the assessment is calculated
Two things drive the number: your industry classification rate and your assessable earnings.
1. Your industry classification rate
Every employer is classified into an industry, and each industry carries a rate reflecting how hazardous that work is. The spread is wide, with low-risk office work near the bottom and heavy industry near the top:
| Industry | Classification rate |
|---|---|
| Banking, Finance & Insurance | 2.24% |
| Educational Services | 3.75% |
| Building & Construction | 7.63% |
| Mining & Quarrying Industries | 14.47% |
The calculator carries the full list of 23 classifications, so you can find yours rather than estimating from these examples.
2. Your assessable earnings
For formal employers, assessable earnings are built from a minimum assessable figure of K1,200 per employee per month, or K14,400 a year, multiplied by your headcount. That subtotal is then increased by 12.5% to give the grand total the rate is applied to.
So for a formal employer:
assessable earnings = employees × K14,400
grand total = assessable earnings × 1.125
assessment = grand total × industry rate %3. The three-part total
The figure you actually pay is not a single year's assessment. WCFCB settles the year just ended and bills the year ahead at the same time:
- Actual assessment, based on the employees you genuinely had in the year that has ended.
- Plus provisional assessment, an estimate for the coming year, based on your projected headcount.
- Less last year's provisional assessment, the estimate you already paid for the year now being settled.
Because the previous provisional amount is subtracted, a total can come out negative. That is not an error. It means you over-estimated your headcount last year and are carrying a credit.
Domestic employers are treated differently
If you employ domestic workers, the earnings-based calculation does not apply. The basis is fixed:
- Zero or one employee: K120 in total.
- Two or more employees: K120 per employee.
The 12.5% uplift does not apply to domestic employers. Your industry classification rate is still applied to that fixed basis.
Why the compliance certificate matters
Once your returns are filed and the assessment is paid, WCFCB issues a compliance certificate. In practice this document is the reason most employers act: it is routinely demanded when bidding for tenders, renewing licences, or contracting with larger companies and government.
An employer who has never registered usually discovers the requirement the week a tender asks for the certificate, by which point back assessments and penalties may already have accrued.
Staying compliant
- Register the business with WCFCB and get classified.
- File returns each year declaring actual and estimated headcount.
- Pay the assessment raised, on time, to avoid penalties.
- Collect your compliance certificate and keep it current.
