Capped NAPSA. PAYE on gross. Zambia payroll, solved.
Zambia payroll is not a flat deduction. It demands a three-authority contribution engine – NAPSA pension capped at a monthly earnings ceiling, NHIMA health levy running uncapped on full gross, and a 0.5% Skills Development Levy – plus a four-band PAYE computed on gross emoluments with no NAPSA relief, and in-country people with direct ZRA, NAPSA and NHIMA relationships. Most providers deliver two of these. Mercans delivers all of them – on a single proprietary stack with no intermediaries.

Payroll compliance: the details that can’t be missed
Zambia’s regulators enforce quietly but retroactively. The ZRA reconciles monthly PAYE against the four bands and expects it computed on gross emoluments – NAPSA and NHIMA are not deductible. NAPSA audits declared earnings against the K37,236 ceiling and charges 10% plus Bank of Zambia interest on shortfalls. NHIMA runs uncapped at 1% each side. The Skills Development Levy at 0.5% is employer-borne and easily forgotten. None of these failures announce themselves – they accumulate silently until an audit makes them very visible.
PAYE computed on the wrong base
Since 1 January 2018 pension contributions are no longer deducted before arriving at chargeable income – PAYE runs on full gross emoluments. Systems that subtract NAPSA (or NHIMA) before applying the 0/20/30/37 bands under-withhold every month, surfacing at ZRA reconciliation with a 5% per-month penalty plus interest.
NAPSA ceiling and under-declaration
NAPSA is 5% employer + 5% employee on earnings up to the K37,236/month ceiling (max K1,861.80 per side for 2026). Running it uncapped over-deducts; under-declaring wages under-remits. Late or short contributions attract a 10% penalty on the unpaid amount plus interest at the Bank of Zambia lending rate.
NHIMA missed or capped in error
NHIMA is 1% employer + 1% employee on full gross with no ceiling – a separate authority, separate registration, separate monthly remittance. Applying the NAPSA cap to NHIMA, or skipping registration, leaves a growing liability that NHIMA recovers with penalties and interest.
Skills Development Levy overlooked
The 0.5% Skills Development Levy is an employer-only cost on gross emoluments, remitted to the ZRA by the 10th – it must never be deducted from employees. Because it is small and invisible on the payslip, it is routinely forgotten by systems not built for Zambia, accruing arrears per period.
The three types of providers who struggle with Zambia
Global Aggregator Platforms
Platforms like Deel, Remote, and Rippling operate through a partner network in Zambia – they don’t own the entity, don’t directly manage ZRA, NAPSA and NHIMA registration, and don’t control the compliance relationship. When the ZRA adjusts PAYE bands or NAPSA revises the ceiling, the instruction travels: platform → partner → your payroll. Each handoff introduces delay and interpretation risk.
- ×No direct ZRA / NAPSA / NHIMA registration – a third party files
- ×PAYE-on-gross base often mis-modelled with NAPSA deducted first
- ×NAPSA K37,236 ceiling and NHIMA uncapped logic tracked manually
- ×Regulatory updates filtered through partner SLAs, not live
Large Global Payroll Incumbents
ADP, Ceridian, and similar incumbents have Zambia coverage – in name. In practice, their Southern Africa coverage is often delivered through regional partners or legacy systems that weren’t built for the capped NAPSA base, the uncapped NHIMA levy, PAYE computed on gross, or the employer-only Skills Development Levy.
- ×NAPSA ceiling hardcoded – not re-based each January
- ×NHIMA and SDL bolted on off-system in spreadsheets
- ×PAYE base and non-resident treatment applied inconsistently
- ×Long implementation timelines – Zambia not a core market
Local Zambian Firms
Local Zambian accounting and bookkeeping firms know the market – but they can’t scale with you. No payroll technology platform, no HRIS integration, no multi-country consolidation, and no data security certifications that multinationals require. Fine for 15 employees in Lusaka. Inadequate at 150 across the region.
- ×No proprietary payroll technology – manual spreadsheet-based processing
- ×No HCM connector – Workday, SAP, Oracle feeds require custom work
- ×No data security certifications (SOC 1/2, ISO 27701, BCR)
- ×No Africa consolidation – cannot report across Zambia + other entities
The only provider that closes every gap
Mercans is the only Zambia payroll provider that combines a proprietary payroll technology stack, full-time in-country compliance teams, direct ZRA, NAPSA and NHIMA relationships, and enterprise-grade data security – simultaneously, on one contract, with no intermediaries.
The only engine built for Zambia’s actual payroll architecture
G2N Nova™ is the world’s only API-first gross-to-net payroll engine. It natively models NAPSA as a capped calculation layer against the K37,236 ceiling, runs NHIMA uncapped at 1% each side, applies the 0.5% Skills Development Levy as an employer-only cost, and computes the four-band PAYE on gross emoluments – with no NAPSA relief – auto-generating ZRA, NAPSA and NHIMA compliance outputs. This isn’t configuration. It’s engineering.
Full-time Zambia team – not a partner you phone when things break
Mercans employs full-time payroll and compliance professionals in Zambia. They maintain active relationships with the Zambia Revenue Authority, the National Pension Scheme Authority, and the National Health Insurance Management Authority – not through a contact directory, but through ongoing regulatory engagement. When the ZRA amends the Income Tax Act, when NAPSA re-bases the ceiling, when NHIMA tightens enforcement – we know before it reaches your inbox.
The security posture multinationals require – and Zambia’s DPA mandates
Zambia’s Data Protection Act No. 3 of 2021 requires data controllers and processors handling personal data to register with the Data Protection Commissioner and maintain documented protection controls. Mercans holds BCR approval, ISO 27701 certification, SOC 1 & 2 certifications, and ISO 27017/27018 – the only payroll provider in the region with this complete certification stack. Zero security breaches since inception.

Since 1 January 2018 pension contributions are no longer deducted before arriving at chargeable income. PAYE runs on full gross emoluments: 0% to K5,100, 20% to K7,100, 30% to K9,200, then 37% – identical bands for residents and non-residents. Deducting NAPSA or NHIMA first under-withholds every month.

These are the compliance details that don’t appear in standard payroll setup guides – but appear in every NAPSA audit, ZRA review, and NHIMA inspection we’ve encountered in Zambia.
PAYE Is Computed on Gross – NAPSA Is Not Deductible
Since 1 January 2018 pension contributions are no longer deducted before arriving at chargeable income. PAYE runs on full gross emoluments across the 0/20/30/37 bands. NHIMA is not deductible either. Systems that subtract NAPSA before applying the bands under-withhold every month for every employee.
NAPSA Is Capped at a Ceiling That Re-Bases Each Year
NAPSA is 5% employer + 5% employee, but only up to a monthly earnings ceiling – K37,236 for 2026, giving a maximum of K1,861.80 per side. The ceiling is re-based annually against National Average Earnings. Running NAPSA uncapped over-deducts from higher earners and mis-states cost.
NHIMA Runs Uncapped – a Separate Authority Entirely
NHIMA is 1% employer + 1% employee on full gross with no ceiling. It is administered by the National Health Insurance Management Authority – separate registration, separate schedule, separate monthly remittance from NAPSA and the ZRA. Applying the NAPSA cap to NHIMA under-remits for every higher earner.
The Skills Development Levy Is Employer-Only
The Skills Development Levy is 0.5% of gross emoluments, borne entirely by the employer and never deducted from the employee, remitted to the ZRA by the 10th of the following month. It is small, invisible on the payslip, and routinely omitted by systems not built for Zambia.
Three Separate Registrations, Three Separate Filings
PAYE and SDL go to the ZRA, pension to NAPSA, and health to NHIMA – three authorities, three registrations, three monthly remittances, all due by the 10th. There is no single combined return. Missing any one leaves a silent liability with its own penalty regime.
Minimum Wage Is Category-Based, Not a Single Figure
Zambia sets minimum wages by category through Statutory Instruments – the 2023 Employment Code Orders (effective 1 January 2024) cover domestic workers (from K1,300/month), general workers, and shop workers on separate scales. There is no single national minimum wage to configure.
Expatriates: Permits Gate Payroll, NAPSA Relief Is Conditional
Foreign employees need a valid employment or work permit before payroll can run. PAYE is identical to residents – the same 0/20/30/37 bands apply. NAPSA may be waived only where equivalent home-country social security cover is documented and approved; NHIMA generally still applies.
Employment Code Act 2019: Leave, Maternity, Severance
Employees accrue 24 days of annual leave (2 days per month of service). Maternity leave is 14 weeks at full pay after 12 months’ service. Redundancy triggers statutory severance, and notice scales with the contract type – all enforced under the Employment Code Act No. 3 of 2019.
One workforce. Two entirely different compliance tracks.
Zambian nationals on full NAPSA and NHIMA coverage vs. foreign and expatriate workers on permit-linked, conditionally-exempt obligations requires two distinct compliance frameworks, two enrolment paths, and two different termination checks. Mercans runs both simultaneously on every pay cycle.
Parallel Compliance Engines
NAPSA and NHIMA enrolment from Day 1. NAPSA at 5% employer + 5% employee up to the K37,236/month ceiling (max K1,861.80 per side), and NHIMA at 1% each side on full gross with no cap. Both are remitted to their own authority by the 10th of the following month.
Progressive PAYE withheld monthly on gross pay. Nothing on the first K5,100, then 20/30/37% bands – computed on gross emoluments, with NAPSA and NHIMA not deductible. Remitted to the ZRA on the monthly ITF/P16 return by the 10th.
Skills Development Levy on top – employer only. A 0.5% levy on gross emoluments, borne by the employer and never deducted from the employee, remitted to the ZRA by the 10th alongside PAYE.
Full leave and termination rights under the Employment Code. 24 working days of annual leave (2 per month), 14 weeks paid maternity after 12 months’ service, statutory severance on redundancy, and notice scaled to the contract type.
A valid work permit is a payroll prerequisite. Foreign employees need an employment or work permit before payroll can run legally. Permits are time-limited and role-specific; running payroll without one exposes the employer to immigration and labour penalties.
PAYE is identical to residents. The same 0/20/30/37 bands apply on gross emoluments – Zambia does not run separate non-resident PAYE tables for employment income. The first K5,100 is tax-free for both.
NAPSA relief is conditional, not automatic. NAPSA may be waived only where equivalent home-country social security cover is documented and NAPSA approves the exemption – otherwise the standard 5%/5% applies up to the ceiling. Mercans confirms each expat’s position before the first run.
NHIMA generally still applies. Health cover for employees working in Zambia typically brings expatriates within NHIMA scope at 1% each side, and the 0.5% employer Skills Development Levy applies to their emoluments as well.
Every obligation. Every authority. Mercans owns the calendar.
Zambia compliance runs across the ZRA, NAPSA and NHIMA on monthly and annual cadences – PAYE, the Skills Development Levy, pension and health contributions all due by the 10th. Mercans’ managed payroll absorbs every filing as standard scope – you don’t track deadlines. We do.
PAYE Monthly Return (ITF/P16)
Per-employee PAYE withheld on the 0/20/30/37 bands and computed on gross emoluments, filed and remitted to the ZRA by the 10th of the following month. Late payment attracts a penalty of 5% per month on the outstanding amount plus interest.
NAPSA Contribution Filing
Employer 5% and employee 5% on earnings up to the K37,236/month ceiling (max K1,861.80 per side for 2026), remitted to the National Pension Scheme Authority by the 10th. Late remittance attracts a 10% penalty plus Bank of Zambia lending-rate interest.
NHIMA Contribution Filing
Employer 1% and employee 1% on full gross with no ceiling, remitted to the National Health Insurance Management Authority by the 10th of the following month. A separate registration and schedule from NAPSA and the ZRA.
Skills Development Levy
0.5% of gross emoluments, borne entirely by the employer and never deducted from employees, remitted to the ZRA by the 10th alongside PAYE. Missing it accrues arrears per period with penalties and interest.
NAPSA & NHIMA Registration on Hire
Every new employee must be registered with NAPSA and NHIMA on hire, with accurate earnings declared. The employer must itself be registered with both authorities and the ZRA before the first payroll can run.
Annual Income Tax Return
The annual return reconciles the charge year’s PAYE against monthly filings and, with provisional tax, settles the final position with the ZRA. Band or base errors – such as PAYE run on the wrong base – surface here for reassessment.
Termination & Severance Settlement
Final settlement applying Employment Code Act notice by contract type, statutory severance on redundancy, and accrued leave encashment. Getting the calculation base and NAPSA/NHIMA stop dates right avoids disputes and re-runs.
Work Permit & DPA 2021 Compliance
Work and employment permits for foreign staff must remain valid and match employment terms, with proactive renewal tracking. Payroll data processing must comply with the Data Protection Act No. 3 of 2021 and Data Protection Commissioner registration.
