NSSF Phase 4 from February 2026: What the New Contribution Rates Mean for Diaspora Workers, Employers, and Returnees

On 1 February 2026, Kenya entered Phase 4 of the National Social Security Fund Act, 2013. With the change, the lower earnings limit rose from KSh 8,000 to KSh 9,000 and the upper limit jumped from KSh 72,000 to KSh 108,000. The contribution rate remains at 6 per cent for both employer and employee, but the maximum monthly contribution per employee climbed from KSh 4,320 to KSh 6,480 per side, for a combined ceiling of KSh 12,960 per employee per month. For diaspora Kenyans who still hold Kenyan pension accounts, who employ domestic workers and house staff at home, or who plan to return to Kenya in the next five years, Phase 4 is more than a payroll line item. It is the most consequential change to Kenya's social security architecture in a decade.

This guide explains the changes, the reasons behind them, the Haba Haba voluntary product designed for the informal sector and the diaspora, and the practical steps every Kenyan abroad should take to make sure their NSSF account is positioned to deliver a meaningful pension at retirement.

The Numbers: What Changed on 1 February 2026

The NSSF Act, 2013 set out a phased increase in contributions over five years. Phase 1 began in February 2023, Phases 2 and 3 followed in 2024 and 2025, and Phase 4 took effect this year. Phase 5 will follow in February 2027 and is expected to align fully with the Kenyan national average wage.

Under Phase 4, contributions are calculated as 6 per cent of pensionable earnings, capped at the new upper limit of KSh 108,000. The structure remains two-tiered: Tier 1 covers earnings up to KSh 9,000, and Tier 2 covers the band between KSh 9,000 and KSh 108,000. Employers can opt out of Tier 2 only if they have an approved private pension scheme registered with the Retirement Benefits Authority. The result is that a Kenyan earning the median formal-sector salary now contributes substantially more to NSSF than under the old NSSF Act, 1965 — but with a corresponding increase in expected retirement benefit.

Why the Change Matters

The 1965 Act capped contributions at a token KSh 400 per month, with the result that the average Kenyan retiring under the old regime received pensions so small they could not pay a single month of rent in Nairobi. The 2013 Act, finally implemented after a long court battle, brings Kenya in line with regional peers like South Africa and Mauritius and creates a real, contributory pension system. For diaspora returnees, this is the difference between a meaningless retirement payout and a credible income floor at 60.

Diaspora Workers and Haba Haba: The Voluntary Route

If you are working in the UK, the US, Canada, the Gulf, or anywhere else, you are not subject to mandatory NSSF deductions. However, NSSF runs Haba Haba, a voluntary contribution product designed precisely for self-employed Kenyans, informal sector workers, and the diaspora. With Haba Haba, you can make voluntary contributions starting from as little as KSh 25 a day or KSh 750 a month, and your contributions accumulate to a pension at retirement.

The advantages of Haba Haba for diaspora Kenyans are real. First, you build a Kenyan pension that is portable when you return. Second, your contributions are invested by NSSF in Treasury bonds, equities, and property, which means your savings track the Kenyan economy. Third, NSSF's recent governance reforms — including the appointment of a Chief Investment Officer and the publication of audited returns — have improved fund credibility significantly. Fourth, the funds can be used for partial withdrawals on emigration, on permanent invalidity, or on the purchase of a first home, subject to NSSF rules.

Registration for Haba Haba can be done online through the NSSF self-service portal, and contributions can be paid via M-Pesa using paybill 333300, or via direct bank transfer. The NSSF website publishes the latest contribution schedules and member statements.

Employers of Domestic Workers: The Often-Forgotten Obligation

Many diaspora Kenyans employ house help, security guards, drivers, and gardeners back home. Under Kenyan law, you are an employer, and you have NSSF obligations for every employee you pay. Under Phase 4, if your house help earns KSh 15,000 a month, you owe an employer contribution of KSh 900 and the employee owes KSh 900 from their salary. For five workers across two properties, the diaspora employer's monthly NSSF bill can easily run to KSh 5,000 — small in absolute terms, large in the legal and social impact of compliance.

Non-compliance carries penalties of 5 per cent of unpaid contributions plus interest at the prevailing CBK rate. NSSF inspectors have started using the integrated database that links NSSF with KRA's iTax, with the Social Health Authority's enrolment system, and with the National Industrial Training Authority. A diaspora employer who pays SHIF for their staff but ignores NSSF is now an easy target for an inspector's audit.

How NSSF Interacts with SHIF/SHA

NSSF and the Social Health Authority are separate institutions with separate contributions. NSSF is the long-term retirement pillar; SHIF is the current-year health insurance pillar. Together with the housing levy and PAYE, the four statutory deductions in Kenya's 2026 payroll consume a meaningful share of any salary. Diaspora returnees often discover that the take-home pay on a KSh 200,000 nominal salary is significantly lower than expected once these four statutory items are netted out. A good payroll calculator that includes Phase 4 NSSF — like the ones published by the CMA-licensed payroll providers — is essential for any returnee negotiating a Kenyan salary.

Investment Returns: Where Your NSSF Money Goes

NSSF is the largest single investor in Kenyan Treasury bonds and one of the top three institutional investors at the Nairobi Securities Exchange. The Fund's investment policy is reviewed by the Retirement Benefits Authority and disclosed in annual reports. In 2024/25, NSSF declared an interest credit of 9 per cent to member accounts, comfortably above inflation and ahead of most bank savings products. Phase 4 contributions are channelled into the same investment pool, which means diaspora members benefit from the same compounding.

Pension Portability and Bilateral Agreements

Kenya has bilateral social security agreements under negotiation with the UK, Germany, and several Gulf states. Once concluded, these agreements will allow diaspora Kenyans to count contributions made in those countries towards their Kenyan pension and vice versa. Until then, Haba Haba remains the cleanest way for a UK-based or Saudi-based Kenyan to build a parallel Kenyan pension that is fully their own.

Returnees: How to Reactivate an Old NSSF Number

If you worked in Kenya before leaving and have an old NSSF number from the pre-2014 era, do not open a new account on your return. Visit the nearest NSSF branch, present your national ID and KRA PIN, and request consolidation. The current online portal makes this easier than it was even two years ago. Old contributions, even when small, carry interest and form part of your final benefit calculation.

What Diaspora Households Should Do This Quarter

First, decide whether to enrol in Haba Haba. The contribution barrier is genuinely low and the long-term upside is real. Second, audit your house staff payroll. Anyone with a monthly cash payment to a domestic worker should formalise the arrangement with a written contract, an NSSF number for the employee, and SHIF registration. Third, check your existing NSSF statement. Members can request a statement by SMS to 50333 with the keyword STATUS followed by their NSSF number. Fourth, if you employ multiple domestic workers, consider engaging a payroll service in Kenya to handle statutory remittances on your behalf.

For complete reference, the Retirement Benefits Authority publishes the regulatory framework that governs both NSSF and approved private schemes. The full text of the NSSF Act, 2013 and subsequent regulations is on the Kenya Law portal.

The Bigger Story

Phase 4 of the NSSF Act is one of the quietest but most important reforms of the past decade. It moves Kenya from a token pension culture to a real one. For diaspora Kenyans, the message is straightforward: a Kenyan pension is no longer a polite fiction. With Haba Haba, with the new contribution ceilings, with the integration into SHIF and iTax, the social security floor under every returnee and every dependent left at home is being raised. The diaspora households that engage with NSSF now — through Haba Haba and through compliance for domestic staff — will retire better than the households that ignore it.
