Why different Nigeria PAYE calculators give you different numbers

3 min read

Run the same salary through two different PAYE calculators and get two different answers back? It's usually not a bug in either tool — it's one of three specific places calculators quietly disagree.

Is NHF mandatory?

National Housing Fund (NHF) contributions have been voluntary for private-sector employees since a 2025 NHF Act amendment — not a flat, mandatory deduction every calculator should apply automatically.

What base does the pension rate apply to?

Guides disagree on what the 8% employee pension rate applies to — some use gross salary, others only basic, housing, and transport allowances. TaxLane sidesteps the dispute entirely: it asks for your actual pension contribution amount rather than computing one from an assumed base, so it never has to pick a side.

Is rent relief capped?

Rent relief is 20% of the annual rent you actually pay, capped at ₦500,000.00 — some calculators list the percentage without the cap, which overstates the relief for anyone paying high rent.

Put this into practice

Enter your own NHF and pension contributions — no guessing a base.
