Work the whole computation yourself, before you trust us with it.

Not a single sum in a box. Each one holds a real register — every asset, employee or invoice you enter — and shows its working line by line. Capital allowance and PAYE run a pre-2026 period on the repealed rules as well as the Nigeria Tax Act 2025.

Asset register

Capital Allowance Calculator

Your whole asset register, pooled by classification and scheduled year by year — with disposals, chargeable gains, and the repealed CITA mechanic for a pre-2026 period.

Try it
Payroll run

PAYE Calculator

A full monthly run — every employee on their own reliefs, band by band, with the pre-run checks and the remittance split by state.

Try it
Period return

VAT Calculator

A full return for the period — output against input, with zero-rated and exempt kept properly apart and the filing date attached.

Try it
Both sides

WHT Calculator

Both sides at once — what you must remit by the 21st, and what you can only claim once the credit note arrives.

What Core Ledger adds is doing this on every transaction, in every period, against books that already agree with the answer — not a one-off number, but a working that survives the person who ran it.
