Kenya NSSF Contributions 2026: New Rates, Tiers and Payroll Impact

Kenya's NSSF payroll deduction changed again in 2026. The National Social Security Fund issued a Year 4 employer notice in February 2026, raising the lower earnings limit to KES 9,000 and the upper earnings limit to KES 108,000. For employees earning at or above the upper limit, the maximum employee deduction is now KES 6,480 per month, matched by another KES 6,480 from the employer.

This guide explains what the 2026 NSSF rates mean on a payslip, how Tier I and Tier II are calculated, how the deduction interacts with PAYE, and what employers should check before remitting payroll. It is written for employees checking a payslip, founders hiring in Kenya, payroll teams moving from Year 3 to Year 4, and finance teams comparing Kenyan statutory costs with other African markets.

All unstable payroll facts in this article were checked on April 24, 2026 against NSSF, KRA, SHA, and Retirement Benefits Authority materials. If you only need the number, use the Kenya NSSF calculator. If you need full take-home pay, use the Kenya PAYE calculator.

Quick Answer: Kenya NSSF Rates in 2026

For Year 4 rates effective from February 2026, the employee contributes 6% of pensionable earnings up to the statutory upper earnings limit. The employer contributes the same amount. The contribution is split between Tier I and Tier II.

The practical change is simple: many employees who were capped under Year 3 now have a larger pensionable base in Year 4. That increases retirement contributions, reduces current cash pay, and changes the taxable employment income used for PAYE calculations.

What Changed in 2026

NSSF's February 2026 employer notice says Year 3 contribution rates ended on January 31, 2026 and Year 4 rates apply from February 2026. The notice lists a lower earnings limit of KES 9,000 and an upper earnings limit of KES 108,000. It also shows the maximum monthly contribution as KES 6,480 for the employee and KES 6,480 for the employer.

The reason the maximum is KES 6,480 is mechanical:

• Upper earnings limit: KES 108,000
• Employee rate: 6%
• Maximum employee contribution: 108,000 x 6% = KES 6,480
• Employer match: another KES 6,480

The increase matters most for employees earning above KES 72,000, because Year 3 used a lower upper earnings limit. In 2026, the cap has moved to KES 108,000, so more salary is included in the pensionable base before the contribution stops increasing.

This does not mean every employee pays KES 6,480. Lower salaries still pay 6% of the relevant pensionable earnings. The maximum only applies when pensionable earnings reach or exceed KES 108,000 for the month.

Tier I and Tier II Explained

The NSSF structure has two layers. Tier I covers pensionable earnings up to the lower earnings limit. Tier II covers pensionable earnings above the lower earnings limit and up to the upper earnings limit. The 2026 limits make the split look like this:

Tier I is always remitted to NSSF. Tier II is more flexible for employers with approved retirement arrangements. The Retirement Benefits Authority says employers that want to remit Tier II contributions into a contracted-out scheme may apply to the Authority under the NSSF contracting-out framework. That is an employer and scheme approval issue, not a unilateral employee opt-out.

For employees, the payslip effect is usually the same at the deduction line: NSSF is withheld from pay. The back-office destination of Tier II can differ if the employer has an approved contracted-out scheme.

Worked Examples Using the 2026 Limits

The safest way to understand NSSF is to calculate the employee and employer sides separately. Each side uses the same 6% rate and the same pensionable limits.

Example 1: KES 50,000 monthly pensionable earnings

An employee on KES 50,000 has not reached the upper earnings limit. The contribution is simply 6% of the whole KES 50,000, split conceptually between Tier I and Tier II.

Example 2: KES 150,000 monthly pensionable earnings

The KES 150,000 earner is capped at the upper earnings limit. NSSF is not 6% of KES 150,000. It is 6% of KES 108,000, because the 2026 pensionable base stops there.

Formula for payroll systems

For a monthly employee contribution in 2026, use:

NSSF employee contribution = 6% x min(pensionable earnings, KES 108,000)

For reporting and Tier II analysis, split it as:

• Tier I = 6% x min(pensionable earnings, KES 9,000)
• Tier II = 6% x max(0, min(pensionable earnings, KES 108,000) minus KES 9,000)

The employer contribution uses the same formula, but it is an employer cost rather than an employee deduction.

How NSSF Interacts With PAYE, SHIF and Housing Levy

NSSF is only one line on a Kenyan payslip. It sits beside PAYE, the Social Health Insurance Fund, and the Affordable Housing Levy. These deductions are not interchangeable, and using the wrong order can produce a wrong take-home pay estimate.

KRA's PAYE materials list contributions made to a registered pension or provident fund or registered individual retirement fund as allowable deductions, subject to a limit of KES 360,000 per year, or KES 30,000 per month. KRA also lists Affordable Housing Levy and SHIF among amounts deductible in determining taxable employment income. That means a correct PAYE workflow starts with gross pay, applies allowable deductions, calculates chargeable pay, applies the tax bands, and then applies the relevant reliefs.

For employees, the cash effect of the 2026 NSSF increase can be partly offset by lower PAYE taxable income. It is not fully offset. A higher NSSF deduction still lowers current take-home pay because the employee is saving more into retirement, while the tax reduction only applies at the employee's marginal tax rate.

If you are comparing job offers, separate employee deductions from employer costs. A KES 150,000 salary with the 2026 maximum NSSF deduction produces a KES 6,480 employee NSSF line and a KES 6,480 employer NSSF cost. The second number is real compensation cost for the employer, but it is not cash paid to the employee.

Employer Compliance Checks for 2026 Payroll

Employers should not treat the NSSF update as a simple change to one flat number. Payroll files, HR systems, contract templates, and offer calculators may all contain old Year 3 assumptions.

1. Replace old caps in payroll software

Any payroll system still capped at KES 72,000 pensionable earnings will under-deduct for employees above that level. Any system still using historical flat amounts such as KES 200 or KES 400 is materially stale for 2026.

2. Check both employee and employer ledgers

NSSF is matched. If the employee line changes and the employer cost projection does not, the monthly payroll journal is incomplete. This matters for budgets, cash flow forecasts, and cost-per-employee reporting.

3. Confirm Tier II destination

If the employer has a contracted-out scheme, confirm the approval status and where Tier II is remitted. RBA guidance makes this an approval process. It should be documented, not assumed.

4. Recheck offer letters and gross-to-net estimates

Many candidates evaluate offers by take-home pay. If an offer calculator still uses Year 3 NSSF, the net pay estimate may overstate take-home for higher earners. Use current NSSF, SHIF, AHL, and KRA PAYE rules when modelling the package.

5. Reconcile deadline calendars

Payroll teams also need remittance calendars. KRA's PAYE guide says PAYE is due by the 9th day of the following month. SHA's employer notice says SHIF contributions from employee salaries must be submitted by the 9th of each month. KRA's Affordable Housing Levy notice says AHL is due by the 9th working day after the end of the month in which the salary or income was due.

Source Set and Verification Notes

Verification date: April 24, 2026. The NSSF limits are unstable because they are part of a phased rollout. Payroll teams should recheck them before running a new calendar year or when NSSF publishes another employer notice.
