NSSF portability when changing jobs in Kenya

NSSF is a lifetime membership. The number issued the first time you were employed is the number every subsequent employer must remit against, and the number you use to claim any benefit at retirement. Yet a surprising share of Kenyans end up with two or three numbers because a new HR desk asked them to register again. This guide covers what to hand your new employer, how to fix duplicates, and how the Tier II pot travels when you change employer.

Starting a new job

1. Give HR your existing NSSF membership number on day one. It goes on the payroll master file.
2. If you have forgotten it, dial *303# or log in to nssf.or.ke with your National ID to retrieve it.
3. HR adds you to the monthly Byproduct return. From next payroll cycle, your contributions post against the same number as before.
4. If HR insists on a fresh registration, decline politely and cite the NSSF one-number rule. Registering twice creates the duplicate you will eventually have to unwind at claim time.

Fixing duplicate NSSF numbers

If you already have two or more numbers, consolidate them. Delay makes the reconciliation harder because contributions keep landing under both.

1. Gather every NSSF card, letter, or portal login you have. Note the numbers.
2. Visit any NSSF branch or a Huduma Centre with an NSSF desk.
3. Present your National ID, all NSSF numbers, and any statements you can print.
4. Fill the Account Merger form. NSSF verifies contribution history under each number.
5. Contributions are moved to the surviving number (usually the oldest). The duplicate is cancelled.
6. Turnaround: 2 to 4 weeks. Check the surviving statement to confirm the sum.

Moving your Tier II pot when you leave

If your previous employer contracted Tier II out to a private scheme, the vested amount is yours. When you leave you have three routes:

• Transfer to the new employer scheme: if the new employer is also contracted out, ask both scheme administrators to arrange a scheme-to-scheme transfer. No tax event.
• Transfer to an Individual Retirement Benefits Scheme (IRBS): any RBA-registered administrator (Zamara, Britam, ICEA, CIC, Enwealth, Kenindia, etc.) can open an IRBS in your name. Transfer is tax neutral. You keep managing the pot until retirement or another rollover.
• Withdraw: allowed but expensive. Under RBA rules a departing member may access their own contributions plus interest, but the employer portion is preserved until retirement age (60 by default, 50 with early-retirement rules). Withdrawn amounts are taxed at graduated PAYE rates on the excess above tax-free thresholds.

Tier I is portable by default

Tier I always stays with NSSF regardless of employer. Nothing moves; the same membership number just keeps accumulating credit. You cannot transfer Tier I to a private scheme.

Do a statement check every year

• Log in at nssf.or.ke or dial *303#.
• Cross-check the last 12 months against your P9. Every P9 should match a contribution line.
• Missing months? Ask your employer for the M-PESA confirmation or bank slip, then raise a Contribution Enquiry on the portal.
• Do the same for any private Tier II scheme via the scheme portal (Zamara, Britam, ICEA, CIC, Enwealth, etc.).

Moving between informal and formal sector

The same number works. If you go from formal employment to freelancing, you continue to contribute voluntarily via paybill 333300 with your membership number as the account. Minimum voluntary contribution is KES 200 per month. When you rejoin formal employment later, hand the same number to the new employer.
