Making untrue declarations under the Nigeria Tax Administration Act (NTAA) exposes taxpayers to significant legal and financial risk. Tax authorities possess growing investigative capabilities to detect discrepancies in filings, and the consequences of submitting false information can be severe.
Under Nigerian tax law, a taxpayer who knowingly makes an incorrect declaration may face civil penalties, including substantial monetary fines. In more serious cases, criminal prosecution may follow, potentially resulting in custodial sentences upon conviction.
Beyond the immediate legal penalties, untrue declarations can trigger extended audits and investigations that may uncover additional liabilities across multiple tax periods. This can compound the taxpayer's exposure and lead to reputational damage that affects business relationships and access to credit.
The NTAA provides tax authorities with powers to demand records, conduct enquiries, and impose assessments where declarations are found to be inaccurate. Taxpayers who cooperate and voluntarily disclose errors may receive more lenient treatment than those whose misstatements are uncovered through audit.
Tax professionals consistently advise that accuracy and completeness in tax declarations are not merely matters of legal compliance but also prudent business practice. The cost of rectifying an untrue declaration, once discovered, typically far exceeds any perceived short-term benefit from underreporting.
Taxpayers are encouraged to seek professional guidance when preparing their declarations and to maintain proper records that substantiate all claims made in their filings with the relevant tax authorities.
