Stanley Omotor, senior consultant at KPMG Law LLP Canada, a law firm affiliated with KPMG LLP Canada, in his article, Counting the Cost and Consequences: Lessons for Nigeria from Canada, South Africa, and the UK, on Small Companies’ Income Tax Rates, examines the small companies zero corporate income tax (CIT) rate in Nigeria, in comparison with similar tax incentives existing in Canada, South Africa, and previously in the United Kingdom. Omotor shows that contrary to reasons often canvassed by policymakers for introducing zero and low CIT rates, evidence shows that the implications of such CIT rates often defeat the purpose for their introduction because such CIT rates result in unintended consequences to the tax system by encouraging tax arbitrage behaviours and inappropriate tax avoidance arrangements. Drawing from the experiences of other countries, Omotor posits that it is not a good idea to provide zero CIT rates for small businesses in Nigeria, given its severe implications for the Nigerian economy.
