Trigger on phrases like "Nigeria WHT", "Withholding Tax Nigeria", "FIRS WHT", "WHT rates Nigeria", "deduct WHT contract Nigeria", "PSC WHT", "NTA 2025 WHT", "WHT credit note", "WHT receipt FIRS", "WHT remittance Nigeria", "WHT on dividends Nigeria", "WHT on royalties Nigeria", "non-resident WHT Nigeria", "treaty WHT Nigeria", "petroleum WHT", or any request involving the classification, deduction, or remittance of Nigerian withholding tax. This skill covers WHT under the Withholding Tax Regulations 1997 (as amended by S.I. 1997 No. 28 and subsequent FIRS notices) for both residents (companies and individuals) and non-residents, including the 2025 transitional regime ahead of the Nigeria Tax Act 2025 (NTA 2025) which will replace and consolidate WHT into a single "tax-at-source" Schedule from 1 January 2026. Out of scope: PAYE (Pay-As-You-Earn on employment income — see ng-paye); VAT withholding by listed government MDAs and oil & gas operators (separate from income-tax WHT — see ng-vat-return); Capital Gains Tax withholding on share disposals; specialist upstream petroleum royalty mechanics beyond standard PSC WHT; bespoke FIRS administrative arrangements for individual taxpayers under the SIRS (state) regime.

Trigger on phrases like "Nigeria VAT", "FIRS VAT", "7.5% VAT", "VAT return Nigeria", "value added tax Nigeria", "TaxPro Max", or any question about VAT computation or filing for businesses in Nigeria.

It does not recompute anything itself — it reconciles upstream outputs, builds the line-by-line return working paper, generates Tax Pro-Max / Remita payment instructions, and produces a reviewer brief and taxpayer action list. ALWAYS read this skill last — it's the capstone.
Use this skill whenever asked about Nigerian Capital Gains Tax. Trigger on phrases like "Nigeria CGT", "Capital Gains Tax Nigeria", "sale of shares Nigeria", "property gains Nigeria", "10% CGT Nigeria", "CGTA Nigeria", "disposal of chargeable assets Nigeria", "Section 30 CGTA", "rollover relief Nigeria", "NGX share disposal tax", "₦100M share threshold", "non-resident CGT Nigeria", or any question about computing, filing, or reporting capital gains on Nigerian chargeable assets.

Out of scope — employer-side payroll PAYE mechanics, PAYE return preparation, monthly PAYE remittance and statutory deductions (see ng-paye); corporate income tax / companies (CIT) and dividend WHT (see ng-cit); petroleum profits tax; partial-year residency and treaty tie-breaker analysis.

This skill is the ORCHESTRATOR — it pulls PAYE rules from `ng-paye` and statutory employer/employee contributions (Pension, NHF, NSITF, ITF, NHIS, EDT) from `ng-statutory-deductions` and sequences them into the correct computation order. ALWAYS read this skill before touching Nigerian payroll computation.
