Zambia Payroll and Income Tax Guide: Everything Employers Need to Know

Introduction

Managing payroll in Zambia involves more than paying salaries it requires compliance with income tax laws and statutory contributions such as PAYE, NAPSA, NHIMA, and SDL. Mistakes in payroll calculations can lead to penalties, employee dissatisfaction, and compliance issues.

This guide explains how payroll works in Zambia and provides practical example calculations, helping both SMEs and large businesses understand exactly what needs to be done.

1. Understanding PAYE (Pay As You Earn)

PAYE is the system for withholding income tax from employees’ salaries. Employers are responsible for deducting the correct amount and remitting it to the Zambia Revenue Authority (ZRA) monthly.

Key Points:

• PAYE rates are progressive, based on monthly income.
• Returns must be filed by the 15th of the following month.
• Accurate calculation is critical to avoid penalties.

2. National Pension Scheme Authority (NAPSA) Contributions

Employers and employees contribute to NAPSA:

• Employee: 5% of gross monthly salary
• Employer: 5% of gross monthly salary

Contributions provide retirement benefits and must be remitted monthly.

3. National Health Insurance Management Authority (NHIMA) Contributions

NHIMA contributions support Zambia’s national health insurance scheme:

• Employee: 1% of gross salary
• Employer: 1% of gross salary

Employers remit contributions alongside payroll.

4. Skills Development Levy (SDL)

The Skills Development Levy funds employee training and professional development:

• Employer: 1% of total payroll (if annual payroll exceeds ZMW 1 million)

5. Example Payroll Calculation

Assumptions:

• Gross monthly salary: ZMW 15,000
• PAYE progressive rates (simplified, for example):
  
  • First ZMW 3,300 → 0%
  • ZMW 3,301 – 4,100 → 25%
  • Above ZMW 4,100 → 30%
• NAPSA: 5% employee + 5% employer
• NHIMA: 1% employee + 1% employer
• SDL: 1% employer

Step 1: Calculate PAYE

• ZMW 3,300 × 0% = ZMW 0
• ZMW 800 × 25% = ZMW 200
• ZMW 10,600 × 30% = ZMW 3,180
• Total PAYE = ZMW 3,380

Step 2: NAPSA Contribution

• Employee: 5% × 15,000 = ZMW 750
• Employer: 5% × 15,000 = ZMW 750

Step 3: NHIMA Contribution

• Employee: 1% × 15,000 = ZMW 150
• Employer: 1% × 15,000 = ZMW 150

Step 4: Skills Development Levy (SDL)

• Employer: 1% × 15,000 = ZMW 150

Step 5: Net Pay for Employee

• Gross Salary: ZMW 15,000
• Less PAYE: ZMW 3,380
• Less NAPSA (Employee): ZMW 750
• Less NHIMA (Employee): ZMW 150
• Net Pay = ZMW 10,720

Total Employer Cost

• Gross Salary + Employer NAPSA + Employer NHIMA + SDL = 15,000 + 750 + 150 + 150 = ZMW 16,050

6. Best Practices for Payroll Compliance

• Maintain accurate employee records and salary histories.
• Use updated PAYE, NAPSA, NHIMA, and SDL rates.
• File returns promptly with ZRA and other authorities.
• Keep detailed documentation for audits and verification.
• Consider a payroll system to automate calculations, generate payslips, and simplify reporting.
