Your payslip lists several deductions between your gross salary and the amount that hits your bank account. If you have ever looked at those lines and wondered what they mean or whether they are correct, this explainer breaks down each one. Use our PAYE calculator to verify your own payslip numbers.
The three mandatory deductions
Every formally employed person in Zambia has three statutory deductions taken from their salary each month:
PAYE - Income tax paid to the Zambia Revenue Authority (ZRA)
NAPSA - Pension contribution paid to the National Pension Scheme Authority
NHIMA - Health insurance contribution paid to the National Health Insurance Management Authority
Your employer deducts these from your salary before paying you, then remits them to the respective authorities on your behalf.
PAYE - your income tax
PAYE stands for Pay As You Earn. It is Zambia's income tax system where tax is collected at source - your employer calculates and deducts it each month rather than you filing annually.
Zambia uses progressive tax bands. This means your salary is split into slices, and each slice is taxed at its own rate:
Monthly Income | Tax Rate |
|---|---|
First K5,100 | 0% (tax-free) |
K5,100 to K7,100 | 20% |
K7,100 to K9,200 | 30% |
Above K9,200 | 37% |
A common misconception is that earning above K9,200 means your entire salary is taxed at 37%. That is not how it works. Only the portion above K9,200 is taxed at 37%. The lower portions are always taxed at their respective lower rates.
Example: If you earn K12,000, you do not pay 37% on K12,000. You pay 0% on the first K5,100, then 20% on the next K2,000, then 30% on the next K2,100, and only 37% on the remaining K2,800.
NAPSA - your pension
NAPSA is Zambia's mandatory pension scheme. Both you and your employer contribute:
Employee contribution: 5% of your gross salary
Employer contribution: 5% of your gross salary (paid separately, not from your pay)
Monthly ceiling: K1,861.80 - if 5% of your salary exceeds this, your contribution is capped here
The ceiling means that if you earn K40,000 per month, your NAPSA contribution is K1,861.80 (not K2,000). The cap was introduced to keep contributions proportionate for high earners.
Your NAPSA contributions build towards retirement benefits, disability benefits, and survivor benefits for your dependants.
NHIMA - your health insurance
NHIMA provides health insurance coverage for all contributing workers and their dependants. The contribution structure is simple:
Employee contribution: 1% of your gross salary
Employer contribution: 1% of your gross salary (paid separately)
Ceiling: None - the 1% applies to your entire salary regardless of how much you earn
NHIMA coverage gives you access to accredited health facilities across Zambia. Your dependants (spouse and children) are also covered under your contribution.
The order of deductions
A question that often comes up: does NAPSA reduce your taxable income? In Zambia, the answer is no. PAYE is calculated on your full gross salary. NAPSA and NHIMA are then deducted separately from what remains. The calculation order is:
Start with gross salary (basic pay + all allowances)
Calculate PAYE on the full gross amount
Calculate NAPSA (5%, capped at K1,861.80)
Calculate NHIMA (1%, no cap)
Net Pay = Gross - PAYE - NAPSA - NHIMA
Checking your payslip is correct
If you want to verify the numbers on your payslip, check these things:
Your gross salary matches your contract (basic pay + agreed allowances)
PAYE matches the progressive band calculation for your gross amount
NAPSA is exactly 5% of your gross, or K1,861.80 if you earn above K37,236
NHIMA is exactly 1% of your gross
Net pay = Gross - PAYE - NAPSA - NHIMA - any other agreed deductions
Our PAYE calculator lets you enter your gross salary and see the exact breakdown instantly - useful for a quick cross-check.
Frequently asked questions
Why is my net pay different each month?
If your gross salary is the same every month, your net pay should be identical. Variations usually come from changes in allowances, overtime, bonuses, or one-off deductions like loan repayments or union dues. Check whether any variable pay components changed between months.
Is NHIMA deducted from my salary?
Yes. NHIMA (National Health Insurance Management Authority) deducts 1% of your gross salary every month with no ceiling. Your employer also contributes a matching 1% on top of your salary. This gives you and your dependants access to accredited health facilities across Zambia.
