Resident companies are liable to corporate income tax (CIT) on their worldwide income while non-residents are subject to CIT on their Nigeria-source income.
The CIT rate is 30% for large companies (Companies with gross turnover greater than N100m), assessed on a preceding year basis (i.e. tax is charged on profits for the accounting year ending in the year preceding assessment).
Investment income paid by a Nigerian resident to a non-resident is sourced in Nigeria and subject to WHT at source, which serves as the final tax.
In respect of business profits, a non-resident company that has a fixed base or a permanent establishment (PE) in Nigeria is taxable on the profits attributable to that fixed base. Non-resident digital companies that have a significant economic presence (to be determined by the Minister of Finance) will be subject to income tax in Nigeria on profit attributable to the taxable presence in Nigeria. Non-resident companies providing professional, consultancy, management and technical (PCMT) services to Nigeria residents will be subject to tax at 10% final tax where such company has a significant economic presence (to be determined by the Minister of Finance) in Nigeria
As such, it is required to register for CIT and file its tax returns. Any WHT deducted at source from its Nigeria-source income is available as offset against the CIT liability save for Non-resident companies carrying out PCMT services where the WHT paid at 10% is deemed to be final tax.
Small company rates
0% for companies with gross turnover of N25m or less.
Medium company rates
20% for companies with gross turnover greater than N25m and less than N100m.
Real Estate Investment Companies
Real Estate Investment Companies approved by the Securities Exchange Commission to operate as a real estate investment scheme in Nigeria will be exempt from income tax on rental income and dividend income earned in a financial year will be exempt from income tax provided that at least 75% of such income are distributed within 12 months.
Petroleum profit tax (PPT)
PPT is a tax on the income of companies engaged in upstream petroleum operations in lieu of CIT.
The PPT rates vary as follows:
- 50% for petroleum operations under production sharing contracts (PSC) with the Nigerian National Petroleum Corporation (NNPC).
- 65.75% for non-PSC operations, including joint ventures (JVs), in the first five years during which the company has not fully amortised all pre-production capitalised expenditure.
- 85% for non-PSC operations after the first five years.
Tertiary education tax
Tertiary education tax is imposed on every Nigerian resident company at the rate of 2% of the assessable profit for each year of assessment. The tax is payable within two months of an assessment notice from the FIRS. In practice, many companies pay the tax on a self-assessment basis along with their CIT.
For companies subject to PPT, tertiary education tax is to be treated as an allowable deduction. For other companies, income/profit taxes are not deductible in arriving at taxable income. Non-resident companies and unincorporated entities are exempt from tertiary education tax.
Minimum tax is payable by companies having no taxable profits for the year or where the tax on profits is below the minimum tax. However, companies in the first four calendar years of business, companies engaged in the agriculture business, or small companies are exempt from minimum tax.
Minimum tax payable is calculated as 0.5% of gross turnover less franked investment income
Non-life insurance companies - 0.5% of gross premium
Life insurance companies - 0.5% of gross income
Alternative tax on distribution
There is a tax on distribution where a company pays a dividend in excess of its taxable profit. Certain profits should be deducted from the dividend that is compared to the taxable profit including dividend income that has suffered withholding tax, profits exempt under the Companies Income Tax, Capital Gains Tax, Petroleum Profit Tax, Industrial Development (Income Tax Relief) Act and retained earnings which had suffered tax previously.
Alternative tax on deemed profit
The law allows the FIRS to assess and charge companies to tax on a fair and reasonable percentage of turnover under the following circumstances:
- When the trade or business produces no assessable profits.
- When the trade or business produces assessable profits that, in the opinion of the Board of the FIRS, are less than might be expected to arise from that trade or business.
- When the true amount of the assessable profits of the company cannot be ascertained.
Local income taxes
CIT is payable only to the federal government. State governments collect income taxes of individuals and unincorporated entities, while local governments are only allowed to collect levies and rates but not income tax.
