Nigeria tax reforms are forcing businesses to overhaul payroll, VAT and withholding systems or face heavy penalties under the new tax regime

The full implementation of Nigeria’s Tax Reform Acts has ushered in a new era of enforcement and operational change, compelling businesses and public institutions to rapidly overhaul payroll, tax reporting and compliance systems to avoid punitive sanctions.

The Nigeria Tax Administration Act, the Nigeria Tax Act, the Nigeria Revenue Service Establishment Act and the Joint Revenue Board Establishment Act collectively reshape how income tax, value added tax and withholding taxes are calculated, reported and enforced.

For individual workers, the reforms offer modest relief. According to the Nigeria Tax Administration Act, individuals earning N800,000 or less per year are now exempt from income tax, while higher earners are subject to graduated rates reaching 25 per cent for incomes above N50 million.

That change is expected to increase take-home pay slightly for lower and middle-income earners by the end of January, while higher earners face increased deductions.

For employers, however, the operational burden is immediate and substantial.

Kenneth Erikume, Partner for Tax Reporting and Strategy at PwC Nigeria, said payroll systems are the most urgent priority for compliance.

Kenneth Erikume warned that payroll software must be updated immediately to reflect the new graduated structure and exemptions.

Failure to do so, Kenneth Erikume said, could expose companies to significant penalties and employee disputes.

The new VAT framework presents both opportunity and risk.

The reforms now allow companies to claim input VAT on services, fixed assets and overheads, not only on goods for resale or production.

This change could deliver powerful cost savings if applied correctly, but only where accounting systems are updated to recognise VAT on costs as recoverable rather than expensed.

The reforms also mandate electronic fiscalisation, including e-invoicing, allowing tax authorities to cross-check transactions across banking, payment and tax identification platforms.

Withholding taxes are now subject to some of the heaviest penalties in the regime.

Failure to deduct or remit correctly attracts penalties of up to 40 per cent of the unpaid amount, plus interest and potential criminal liability.

Kenneth Erikume said that errors, not just evasion, now carry severe consequences.

Vendor compliance has also become a critical issue.

Companies face fines of up to N5 million for engaging suppliers without valid Tax Identification Numbers, a requirement that now extends even to informal vendors and reimbursement transactions.

Corporate and technology lawyer Nneoma Agwu-Okoro said businesses must shift from reactive to proactive compliance.

Nneoma Agwu-Okoro said high-volume and digital businesses, including fintechs, are particularly exposed because small errors across large transaction volumes can quickly accumulate into liabilities exceeding profits.

The reforms also strengthen enforcement powers, including daily penalties for late filings, automatic interest tied to financial benchmarks, and sector-specific sanctions for petroleum and mineral operators, including licence risks and asset seizure.

Tax authorities can now cross-reference banking records, tax filings and fiscalisation systems in near real time, making concealment increasingly difficult.

PwC Nigeria advised businesses to register properly, automate compliance wherever possible, maintain strong documentation and ensure that all internal processes are based on the final versions of the laws passed by the National Assembly.

The overarching shift is cultural as much as technical.
