These are the official progressive income tax bands set by the Zambia Revenue Authority (ZRA) for the 2025 charge year, in force from 1 January 2025. Only the income falling within each band is taxed at that band's rate.
| Band | Monthly Taxable Income | Rate | Max Tax in Band |
|---|---|---|---|
| 1 | K 0 – K 5,100 | 0% | K 0.00 |
| 2 | K 5,101 – K 7,100 | 20% | K 400.00 |
| 3 | K 7,101 – K 9,200 | 30% | K 630.00 |
| 4 | Above K 9,200 | 37% | Unlimited |
| Band | Annual Taxable Income | Rate | Max Tax in Band |
|---|---|---|---|
| 1 | K 0 – K 61,200 | 0% | K 0.00 |
| 2 | K 61,201 – K 85,200 | 20% | K 4,800.00 |
| 3 | K 85,201 – K 110,400 | 30% | K 7,560.00 |

Source: Zambia Revenue Authority (ZRA), Income Tax Act Cap. 323 of the Laws of Zambia. Effective 1 January 2025. Note: PAYE bands are applied to taxable income (gross pay minus NAPSA), not gross pay directly.
Beyond PAYE income tax, Zambian employees are subject to two additional mandatory monthly deductions.
The National Pension Scheme Authority (NAPSA) is Zambia's mandatory pension fund. Your 5% is matched by your employer (10% total). In 2025, contributions are capped at K1,708.20/month (based on a ceiling of K34,164). NAPSA reduces your taxable income for PAYE, so a higher NAPSA deduction means less income tax.
The National Health Insurance Management Authority (NHIMA) funds Zambia's public health insurance. Employees contribute 0.5% and employers match 0.5%, totalling 1% combined. Unlike NAPSA, NHIMA does not reduce your taxable income for PAYE. Both employer and employee NHIMA contributions are due to NHIMA by the 10th of the following month.
The Skills Development Levy (SDL) is paid entirely by the employer — it does not affect your take-home pay. From 2025, SDL is tax-deductible for employers against corporate income tax, an important change for payroll compliance. Employees make no SDL contribution and SDL is therefore excluded from our personal take-home calculation.
A step-by-step walkthrough of exactly how ZRA computes your monthly income tax using the official 2025 progressive bands.
Add your basic salary plus all cash emoluments: housing allowance, transport allowance, bonuses, overtime, commissions, and any other cash benefits.
Gross = Basic Salary + All Allowances
Multiply gross pay by 5% to get your NAPSA employee contribution. Cap the result at K1,708.20 — the 2025 NAPSA ceiling.
NAPSA = min(Gross × 5%, K1,708.20)
Your taxable income is gross pay minus the NAPSA deduction. This is the amount the ZRA PAYE bands are applied to.
Taxable Income = Gross − NAPSA
Apply each band only to income within that slice: 0% on K0–K5,100 · 20% on K5,101–K7,100 · 30% on K7,101–K9,200 · 37% on the remainder above K9,200. Sum the results for total PAYE.
NHIMA is charged on gross pay and calculated separately from PAYE. It does not reduce taxable income.
NHIMA = Gross × 0.5%
Subtract all statutory deductions from gross pay to arrive at the amount deposited into your account each month.
Net Pay = Gross − NAPSA − PAYE − NHIMA
A detailed calculation for an employee earning K15,000 per month gross in Zambia using 2025 ZRA PAYE tax bands, NAPSA, and NHIMA.
| Step | Calculation | Amount (ZMW) |
|---|---|---|
| Gross Pay | Basic + Allowances | 15,000.00 |
| NAPSA (5%) | min(15,000 × 5%, 1,708.20) → 750 exceeds cap, use cap | − 1,708.20 |
| Taxable Income | 15,000 − 1,708.20 | 13,291.80 |
| PAYE Band 1 (0%) | 0% × K5,100 | 0.00 |
| PAYE Band 2 (20%) | 20% × (7,100 − 5,100) = 20% × 2,000 | 400.00 |
| PAYE Band 3 (30%) | 30% × (9,200 − 7,100) = 30% × 2,100 | 630.00 |
| PAYE Band 4 (37%) | 37% × (13,291.80 − 9,200) = 37% × 4,091.80 | 1,513.97 |
| Total PAYE | 0 + 400 + 630 + 1,513.97 | − 2,543.97 |
| NHIMA (0.5%) | 15,000 × 0.5% | − 75.00 |
| ✅ Net Take-Home Pay | 15,000 − 1,708.20 − 2,543.97 − 75.00 | 10,672.83 |
Effective PAYE rate: K2,543.97 ÷ K15,000 = 16.96% | Total deduction rate: K4,327.17 ÷ K15,000 = 28.85% | Take-home ratio: K10,672.83 ÷ K15,000 = 71.15%

This Zambia PAYE calculator was built and is maintained by payezambia.com, a Zambian-owned platform dedicated to providing accurate, locally relevant finance tools and information for Zambian workers, employers, and HR professionals.
The 2025 PAYE tax bands used in this tool are sourced directly from the Zambia Revenue Authority (ZRA) and the Income Tax Act, Chapter 323 of the Laws of Zambia. NAPSA contribution rates and the 2025 ceiling of K1,708.20 are sourced from the official National Pension Scheme Authority (NAPSA) annual notice. NHIMA contribution rates are per the National Health Insurance Management Authority Act.
We review and update this calculator at the start of each charge year when ZRA publishes new tax bands, and whenever NAPSA or NHIMA announce rate or ceiling changes. We recommend verifying results against your payroll department or a qualified Zambian accountant for payroll compliance decisions.
