Section 2 -- Required inputs and refusal catalogue
Required inputs
Before computing, you MUST obtain:
- Employment status -- self-employed, informal sector, or voluntary?
- Monthly declared income -- determines SHIF and NSSF
- Registered with SHA?
- Registered with NSSF?
- Any formal employment alongside? -- dual status
- Sector -- formal vs informal
If monthly income is unknown, request estimate. SHIF uses declared household income.
Refusal catalogue
R-KE-SOC-1 -- Court challenges to SHIF. Trigger: question about SHIF constitutionality. Message: "There have been multiple court challenges to the Social Health Insurance Act. Escalate -- do not advise on constitutional matters."
Prohibitions
- NEVER use old NHIF brackets from October 2024 onward -- SHIF 2.75% applies
- NEVER tell self-employed that NSSF is mandatory -- it is voluntary for self-employed
- NEVER ignore KES 300 SHIF minimum
- NEVER assume NSSF uncapped -- Upper Earnings Limit KES 72,000 caps the base
- NEVER conflate SHIF household income with individual income without clarifying
- NEVER present old NSSF rates (pre-February 2025)
- NEVER assume foreign residents exempt from SHIF -- residency triggers obligation
