NSSF Tier Changes in February 2025: Updating Kenyan Payroll Before Month-End

Kenya’s NSSF contribution structure did not stay still after 2024. By February 2025, payroll teams had to apply updated Tier 1 bases and higher ceilings for Tier 2 — or risk under-collecting employee and employer contributions.

Why “one NSSF formula forever” fails

A payroll engine that hard-codes a single NSSF table will be wrong every time the law or gazette updates the tiers. World Ledgers versions NSSF by payroll year and month (2024 rules, 2025 rules, 2026 rules) so historical payslips stay auditable while new months use the current tiers.

What finance should do at month-end

• Confirm the payroll period month before finalizing
• Spot-check employees near the old and new ceilings
• Reconcile NSSF remittance totals to the payroll summary
• Keep P9 and annual reports aligned with monthly stored values
