Understanding SHIF Deductions
Published: June 15, 2026 • Kenya Tax Guides • 4 min read
The Social Health Insurance Fund (SHIF) constitutes Kenya's transformed public healthcare financing framework, enacted under the Social Health Insurance Act (SHIA), 2023. Replacing the decades-old National Hospital Insurance Fund (NHIF) Act of 1998, SHIF is administered by the newly constituted Social Health Authority (SHA). Designed to achieve Universal Health Coverage (UHC), the scheme fundamentally restructures payroll deductions, eliminating legacy flat caps and introducing an income-based progressive model.
Core Contribution Rate and Structure
Under Section 27 of the Social Health Insurance Act and its accompanying regulations:
- Formal Sector Employees: Subject to a statutory deduction of 2.75% of gross monthly household income.
- Minimum Floor: A statutory minimum contribution of KES 300 per month is established for individuals whose calculated deduction would otherwise fall below this threshold.
- Elimination of the Maximum Cap: Unlike the legacy NHIF model, which capped monthly deductions at KES 1,700 for any employee earning KES 100,000 or above, SHIF has no upper statutory ceiling for salaried employees. Every shilling earned is subject to the 2.75% levy.
NHIF vs. SHIF: Key Structural Changes
Understanding how SHIF differs from the former NHIF framework is vital for evaluating payroll impact:
| Feature | Former NHIF System | Modern SHIF System |
|---|---|---|
| Governing Legislation | NHIF Act, 1998 | Social Health Insurance Act, 2023 |
| Contribution Formula | Graduated step tiers (KES 150 to KES 1,700) | Flat 2.75% of gross monthly earnings |
| Upper Ceiling | Capped at KES 1,700/month | No statutory cap |
| Minimum Contribution | KES 150 (employed) / KES 500 (voluntary) | KES 300/month |
| Insurance Relief | 15% of contribution (max KES 255/month) | 15% of total SHIF deduction |
The Three Established Healthcare Funds
Under the Social Health Authority, revenue collected through SHIF is channeled into three distinct statutory health pools designed to provide comprehensive medical coverage:
- Primary Healthcare Fund: Fully government-funded to provide free primary medical care and preventative outpatient services at Level 1, Level 2, and Level 3 dispensaries and health centers.
- Social Health Insurance Fund (SHIF): Covers inpatient and outpatient medical services, surgical procedures, maternal care, and rehabilitative services at contracted Level 4, 5, and 6 referral hospitals.
- Emergency, Chronic & Critical Illness Fund: Finances treatments for life-threatening medical emergencies, cancer oncology care, specialized dialysis, stroke interventions, and intensive critical ICU management once SHIF benefit limits are reached.
Worked Payroll Calculations Across Salary Levels
The table below demonstrates the net payroll impact of the 2.75% SHIF deduction and its accompanying 15% Insurance Relief:
| Gross Monthly Salary | Monthly SHIF (2.75%) | Former NHIF Rate | Insurance Relief (15%) | Net Monthly Cost |
|---|---|---|---|---|
| KES 30,000 | KES 825.00 | KES 900.00 | KES 123.75 | KES 701.25 |
| KES 75,000 | KES 2,062.50 | KES 1,400.00 | KES 309.38 | KES 1,753.12 |
| KES 150,000 | KES 4,125.00 | KES 1,700.00 | KES 618.75 | KES 3,506.25 |
| KES 300,000 | KES 8,250.00 | KES 1,700.00 | KES 1,237.50 | KES 7,012.50 |
Remittance Deadlines and Employer Duties
Employers must deduct and remit SHIF contributions on or before the 9th day of the following calendar month. Remittance is completed through the Social Health Authority employer portal or via the unified payroll return integrated with KRA iTax. Late remittances attract a statutory surcharge penalty of 2% per month or part of a month on the unpaid amount, alongside potential suspension of employee healthcare coverage benefits.
