Withholding tax is deducted by your customer and remitted to the relevant tax authority on your behalf. It reduces the cash you receive but is generally an advance income-tax credit, so keep the withholding-tax credit note.
Common Nigerian rates include 5% and 10%, but the correct rate depends on the payment category, payee type, exemptions, and sometimes treaty rules. WHT is normally calculated on the goods or service value before VAT: on a ₦500,000 invoice plus ₦37,500 VAT, the WHT base is ₦500,000.
Use the free WadMaster WHT calculator for common cases and confirm the applicable rate with the Nigeria Revenue Service guidance or a tax adviser before remitting.

Your business and transaction details remain the main document content. Inside a WadMaster account, Free and Starter invoices also keep the WadMaster line, and Pro removes it.
