NHF is now voluntary in Nigeria: what changed under NTA 2025

For three decades the National Housing Fund (NHF) was a mandatory 2.5% deduction from every private-sector Nigerian salary earning at least ₦3,000 a month. The Nigeria Tax Act 2025 (NTA 2025) changed that on 1 January 2026: NHF is now voluntary for private-sector employees. Mandatory status is preserved only for federal public-service staff.

That one-word change — voluntary — rewrites how you run payroll, what your employment contracts should say, and who can still use their contributions to unlock an FMBN housing loan.

The headline change

Before (up to 31 Dec 2025)	After (from 1 Jan 2026)
Mandatory for every private-sector employee earning ≥ ₦3,000/month	Voluntary for private-sector employees
Payroll deducts 2.5% of basic salary automatically	Payroll deducts only if the employee has opted in
Opt-out not legally available	Opt-out is a legal right exercisable at any time
Employer must remit on behalf of every employee in scope	Employer remits only for opted-in employees

The rate itself is unchanged at 2.5% of basic salary. What changed is the default.

Why the law moved

Mandatory NHF dated from the NHF Act 1992 — historical context, pre-2022 and no longer the headline authority for payroll decisions. The criticism accumulated over 30 years: low withdrawal rates, a small fraction of contributors ever receiving an FMBN mortgage, and de-facto forced savings that many employees wanted redirected into personal instruments with better returns.

NTA 2025 resolved that by flipping the consent model. The fund still exists, mortgage access still runs through FMBN, but participation is now the employee's choice — as it has been since inception for the self-employed.

1. What you must do by 31 January 2026

Three concrete payroll actions:

1. Default every private-sector employee to opted-in on the system. This preserves continuity for staff who already have NHF numbers and active contribution histories; they don't lose their position in the FMBN queue because of a legal change.
2. Expose an opt-out switch in self-service. Every employee must be able to opt out in two clicks, with the change effective from the next payroll period.
3. Stop deducting from opted-out employees on the next payroll run. Continuing to deduct after an opt-out is an unauthorised deduction — the Labour Act penalties are separate from NHF/FMBN and bite harder.

Federal public-service employees are out of scope for the opt-out — they remain mandatorily contributory under NTA 2025.

2. How the deduction works for opted-in employees

Mechanics haven't moved. For an employee on ₦3,600,000 annual basic:

NHF = ₦3,600,000 × 2.5% = ₦90,000 / year ≈ ₦7,500 / month

Base is basic salary only — not gross, not BHT. A common spreadsheet error is applying 2.5% of gross; that over-deducts by roughly 60–70% for typical Nigerian salary structures.

The deduction is pre-tax under NTA 2025 — it reduces chargeable income before the PAYE brackets are applied. Net cost to a typical opted-in employee is lower than the headline 2.5% because PAYE falls by roughly 15–25% of the deduction, depending on their marginal bracket.

3. Remittance and FMBN mortgage eligibility

Opted-in contributions are remitted to FMBN via the contributor's NHF number. FMBN's own 2024 circulars on mortgage eligibility set the current window: typically 6 months of consecutive contributions before a member can apply, but confirm the exact figure with your relationship manager — FMBN has revised thresholds more than once since 2022 and the current window is the one that binds.

For employees considering opt-out, the trade-off is straightforward:

• Opt out: keep the 2.5% in take-home, redirect to a personal savings or investment vehicle, lose FMBN mortgage pathway until they opt back in and accrue the required consecutive months again.
• Stay opted in: continue building FMBN eligibility for the subsidised housing loan, accept the 2.5% cost now.

A ₦3.6M-basic employee choosing to opt out frees roughly ₦7,500/month — meaningful, but far less than the subsidised interest differential on a successful FMBN mortgage over 20 years. The choice is real and rational either way.

4. Opt-back-in mechanics

An employee who opts out can opt back in later, but most well-run payroll systems gate the reversal behind an admin approval step. Two reasons:

1. Audit trail. If FMBN queries why contributions resumed mid-year, the admin approval record and the opt-back-in date establish the timeline.
2. Preventing churn. Without a lightweight check, staff flip monthly in response to cash-flow anxiety; the PFC remittance reconciliation becomes a full-time job.

A notification-based approval (employee submits → HR admin approves → next payroll picks up the change) is the pattern most teams land on.

5. What to put in your 2026 employment contracts

New hires from January 2026 onwards should sign contracts that explicitly record the NHF election:

• State that NHF is voluntary under NTA 2025.
• Capture the employee's initial election (opt in / opt out) at signing.
• Reference the self-service mechanism for changing that election later.

Existing contracts don't need renegotiation — the law changed the default, not the contractual minimum — but audit-ready HR teams update the handbook and include a "NHF 2026" addendum at the next performance review cycle.

6. Interaction with the rest of the NTA 2025 statutory stack

NHF sits alongside the other 2026 statutory deductions. On a typical monthly payslip:

• Pension — 8% of BHT, still mandatory, unchanged by NTA 2025
• NHF — 2.5% of basic, voluntary from 1 January 2026
• NHIS / NHIA — employer-enrolment only
• PAYE — six brackets at 0% / 15% / 18% / 21% / 23% / 25% under NTA 2025

See our PAYE guide under NTA 2025 for how these deductions flow into the chargeable-income calculation.

Common mistakes in the transition

1. Deducting NHF by default. The 2026 default in law is now opt-in, not opt-out. A payroll system still deducting automatically is making an unauthorised deduction from every staff member who hasn't explicitly elected. Fix this before the January payroll run.
2. Applying 2.5% to gross pay. The base is basic salary only. Applying it to gross over-deducts and over-remits.
3. Freezing contribution records for opt-outs. An employee who has opted out still owns their historical NHF number and accumulated contribution balance; don't close the ledger, just stop adding to it.
4. Ignoring the federal-public-service carve-out. NTA 2025 preserved mandatory NHF for federal public-service employees. A generic "everyone is voluntary now" flag in payroll is wrong if you process any public-sector clients.
5. Treating opt-back-in as an instant toggle. Route it through admin approval so the audit trail reflects a decision, not a glitch.

Historical context: NHF Act 1992

Pre-2022 authority — kept here only for reference. The NHF Act 1992 set the original 2.5%-of-basic contribution, the ₦3,000/month minimum income threshold, and the FMBN administration framework. Every provision of that Act that touched mandatory private-sector contribution was superseded by NTA 2025 on 1 January 2026. Payroll calculations for periods up to 31 December 2025 still cite the 1992 Act; calculations from 1 January 2026 cite NTA 2025.

Does AnooreHR handle this?

Yes — AnooreHR treats NHF as a profile-driven deduction. Under the 2026 tax profile, new hires default to opted-in with a one-click opt-out in their self-service portal. Opt-back-in is gated behind an HR admin approval with full audit-log capture. Contributions only flow to FMBN for opted-in staff, remittance schedules are generated per PFC, and the deduction is correctly applied to basic salary only for the whole chain — PAYE reduction, payslip, and GL posting.
