Withholding Tax and Corporate Income Tax in Nigeria

Beyond VAT and e-invoicing, two other tax obligations shape how Nigerian businesses handle payments and profits: Withholding Tax and Corporate Income Tax. Here’s the short version of each, and how they connect to the invoicing side of your business.

Withholding Tax (WHT)

Withholding Tax is an advance deduction of tax at the point of payment, applied to specified transaction types — common examples include payments for contracts, professional or consultancy services, rent, dividends, interest, and royalties. The party making the payment deducts WHT and remits it to the tax authority on behalf of the recipient, rather than the recipient paying it separately later.

WHT isn’t an additional tax on top of everything else — it’s typically an advance credit: the amount withheld during the year is offset against the recipient’s final tax liability (often their CIT, for companies), rather than being a separate, permanent tax burden.

Rates vary by transaction type and have been subject to periodic adjustment, so confirm the applicable rate for your specific transaction with current NRS guidance rather than a fixed figure.

Corporate Income Tax (CIT)

Corporate Income Tax is the tax charged on a company’s profits for the year. Historically, Nigeria’s CIT structure has scaled by company size (with different treatment for small, medium, and large companies), and the specific rates and thresholds have changed under recent tax reforms. As with WHT, confirm current rates and thresholds with NRS or a qualified tax professional — this guide is intentionally not quoting specific figures that could be outdated by the time you read it.

How WHT and CIT Relate

The two connect directly: WHT deducted from a company’s income during the year is generally creditable against that company’s CIT liability at year-end. Getting WHT documentation right during the year — accurate records of what was deducted, by whom, and on what transaction — directly simplifies the CIT filing process later. Sloppy WHT records mean a harder, more error-prone CIT reconciliation.

Where This Connects to E-Invoicing

E-invoicing is primarily a VAT compliance mechanism, but the underlying invoice data — who was paid, for what service or goods, and how much — is the same data that determines correct WHT deduction and feeds into CIT profit calculation. A business with clean, structured, real-time-validated invoice records is better positioned across all three tax obligations, not just VAT. This is one reason compliant e-invoicing has knock-on benefits beyond the VAT requirement itself.

Keep Your Records Straight Across All Three

Whatever your WHT and CIT obligations, the record-keeping discipline is the same one that applies to VAT and e-invoicing: accurate documentation, retained for the required period, and organized well enough to survive an audit. See our record-keeping guide for the specifics, and our e-invoicing compliance hub for the VAT side of your compliance picture.
