Tax Disputes

We challenge unlawful tax assessments and represent taxpayers at every tribunal level.

Time-Sensitive

Assessment objection windows are short and non-extendable. If you have received a tax assessment you believe is incorrect, contact us before the objection deadline.

No institution — government agency, revenue authority, or public official — is above the law. Tax disputes in Nigeria are complex, time-sensitive, and carry significant consequences if handled incorrectly. Assessment objection windows are short. Procedural errors at the Tax Appeals Tribunal level can affect outcomes on appeal. And most revenue authority assessments are open to challenge on both technical and substantive grounds.

The firm challenges unlawful tax assessments, enforces compliance obligations on revenue authorities, and pursues fundamental rights violations arising from improper revenue agency conduct. The practice covers FIRS income tax, VAT, withholding tax, and transfer pricing matters at federal level, and State Internal Revenue Service assessments at state level.

For businesses that are not yet in dispute, pre-dispute advisory — structuring transactions to minimise tax exposure within the law, ensuring documentation is in order, and understanding the basis of assessments before objecting — is consistently more valuable than reactive litigation. The firm offers both.

Why SAN-Led Representation

Tax proceedings that escalate to the Federal High Court and beyond require advocacy at a level that carries weight with the judiciary. The SAN designation brings institutional credibility that affects how contested tax matters are received at the highest court levels. For large assessments and matters of principle, the quality of senior representation is a material variable.
