Corporate Income Tax Return (Kenya)

A Corporate Income Tax Return in Kenya records the income, deductions and tax due for the period it covers.

The standard corporate income tax rate in Kenya is 30% of chargeable income for resident companies under the First Schedule to the Income Tax Act (Cap. 470). Special rates apply to certain categories of companies: newly listed companies on the Nairobi Securities Exchange (NSE) may qualify for a reduced rate of 25% for five years under Section 7 of the Income Tax Act; companies operating in Special Economic Zones (SEZs) established under the Special Economic Zones Act No. 16 of 2015 benefit from a 10% rate for the first ten years and 15% thereafter; and companies manufacturing goods in Kenya and exporting at least 80% of output enjoy a 15% rate. The Kenya Revenue Authority (KRA) administers these rates under the authority of the Income Tax Act (Cap. 470), the Tax Procedures Act No. 29 of 2015, and annual Finance Acts that modify rates and introduce reliefs.

The year of income for corporate income tax purposes in Kenya runs from 1 January to 31 December, though companies may apply to the Commissioner of Domestic Taxes to use a substituted year of income consistent with their accounting year end under Section 27(4) of the Income Tax Act (Cap. 470). The corporate income tax return for a given year of income must be filed with the KRA through the iTax platform by the last day of the sixth month following the end of the year of income — for a 31 December year end, this is 30 June of the following year. Late filing attracts a penalty under Section 83 of the Tax Procedures Act No. 29 of 2015 of 5% of the tax due per month, up to a maximum of 20% of the tax due, plus interest on unpaid tax at 1% per month.

Instalment tax — also known as advance tax or pay-as-you-earn for companies — is payable by companies with taxable income on a quarterly basis during the year of income. Under Section 12 of the Income Tax Act (Cap. 470) and the Instalment Tax Rules, instalment tax is due in four equal payments on the 20th of April, June, September, and December of the year of income, each equal to 25% of the estimated annual tax liability. A company that underpays instalment tax by more than 10% of the actual tax liability faces an additional 20% penalty on the shortfall under Section 83B of the Tax Procedures Act No. 29 of 2015.

Allowable deductions for corporate income tax purposes in Kenya are governed by Sections 15 and 16 of the Income Tax Act (Cap. 470). Section 15 allows deductions for expenses that are wholly and exclusively incurred in the production of income — including employee salaries and statutory contributions (PAYE, NSSF, SHIF, Housing Levy), business interest, rent and rates, depreciation at prescribed rates under the Second Schedule (investment deductions), and marketing and advertising expenses. Section 16 of the Income Tax Act (Cap. 470) lists specifically disallowed deductions — including capital expenditure (except investment deductions), personal expenditure, income tax paid, and fines and penalties. The proper computation of allowable deductions is critical to accurate corporate tax return preparation and is examined by the KRA's Domestic Taxes Department during audit.

Withholding tax paid on the company's income — including dividends received from resident companies, interest from financial institutions, and royalties from intellectual property under the Withholding Tax Schedule to the Income Tax Act (Cap. 470) — may be credited against the company's annual corporate income tax liability. Companies must reconcile withholding tax certificates (WHT certificates) obtained from payers with the KRA iTax platform records before filing the annual return.

A Corporate Income Tax Return in Kenya must be filed by every company chargeable to income tax for each year of income, and several circumstances make accurate return preparation particularly important.

A Corporate Income Tax Return is required for every company incorporated under the Companies Act No. 17 of 2015 and registered as a taxpayer with the Kenya Revenue Authority (KRA) using a KRA PIN obtained through the iTax platform. The return must be filed by the deadline prescribed under Section 52 of the Income Tax Act (Cap. 470) — the last day of the sixth month following the end of the company's year of income — or the company and its directors face penalties and interest under the Tax Procedures Act No. 29 of 2015.

A Corporate Income Tax Return is needed when a company has received income during the year of income — including trading income, rental income, interest, dividends from foreign companies, royalties, management fees, and any other income assessable to tax under Part II of the Income Tax Act (Cap. 470). Even a company with no taxable income after deductions must file a nil return on the KRA iTax platform to avoid a late filing penalty.

A Corporate Income Tax Return is required when a company wishes to claim investment deductions under the Second Schedule to the Income Tax Act (Cap. 470) — including capital allowances on plant and machinery, industrial buildings, and wear-and-tear deductions on business assets. These deductions are claimed in the annual return and reduce the company's taxable income for the year.

A Corporate Income Tax Return is needed when a company has unutilised tax losses carried forward from previous years under Section 15(4) of the Income Tax Act (Cap. 470), which allows losses from a year of income to be carried forward and set off against income in subsequent years for up to four years (extended to five years for companies in manufacturing under the Finance Act 2023). Loss relief claims must be made in the annual return.

A Corporate Income Tax Return is required by financial institutions — including commercial banks licensed by the Central Bank of Kenya (CBK), insurance companies regulated by the Insurance Regulatory Authority (IRA), and microfinance banks — as evidence of a company's tax compliance status. The KRA Tax Compliance Certificate (TCC), required for public procurement under the Public Procurement and Asset Disposal Act No. 33 of 2015, is only issued to companies with a current filing record on the iTax platform.

A Corporate Income Tax Return is needed when the KRA has issued a notice of audit or investigation under Section 59 of the Tax Procedures Act No. 29 of 2015 and requires the company to submit its returns and supporting records for examination. Accurate and timely returns reduce the risk of additional tax assessments under Section 31 of the Tax Procedures Act.

A Corporate Income Tax Return in Kenya under the Income Tax Act (Cap. 470) and the Tax Procedures Act No. 29 of 2015 requires the following essential information and computations.

Company Identification: The company's legal name, KRA PIN, Business Registration Service (BRS) registration number, the year of income being reported (1 January to 31 December, or the approved substituted year), and the company's principal business activity as classified under the Kenya National Bureau of Statistics (KNBS) business activity codes used by the KRA iTax system.

Gross Income Computation: Total gross income from all sources assessable under Part II of the Income Tax Act (Cap. 470) — trading income per audited financial statements, rental income from immovable property, interest income, dividends from foreign companies, royalties, management fees received, and other assessable receipts. Exempt income (dividends from resident companies under Section 7(3) of the Income Tax Act) must be identified and excluded.

Allowable Deductions (Section 15): Total allowable deductions under Section 15 of the Income Tax Act (Cap. 470) — salaries and wages (net of disallowed personal expenditure), NSSF employer contributions, SHIF contributions, Housing Levy employer contributions, business interest (subject to thin capitalisation rules under Section 16(2)(j) limiting deductible interest to 30% of EBITDA for companies with related-party debt above KES 1 billion), rent and rates, marketing and advertising, bad debts written off (subject to Section 15(2)(g) conditions), and legal and professional fees for income-producing activities.

Capital Allowances (Second Schedule): Investment deductions and wear-and-tear allowances on business assets under the Second Schedule to the Income Tax Act (Cap. 470). Standard wear-and-tear rates include: computers and peripherals at 25% per year (reducing balance); motor vehicles at 25% per year; plant and machinery at 12.5% per year; and industrial buildings at 10% initial allowance plus 2.5% per year. These allowances reduce the tax written-down value of assets and directly reduce taxable income.

Chargeable Income: Gross income minus allowable deductions and capital allowances, plus any disallowable expenditure added back under Section 16 of the Income Tax Act (Cap. 470). Loss relief from prior years under Section 15(4) is deducted at this stage.

Tax Payable: Chargeable income multiplied by the applicable corporate tax rate (30% for resident companies; 37.5% for non-resident companies with a permanent establishment in Kenya under the Third Schedule; reduced rates for qualifying companies). The tax payable is then reduced by: withholding tax credits backed by WHT certificates from the KRA iTax platform; instalment tax paid during the year (backed by payment receipts from iTax); and any foreign tax credits under double taxation agreements (DTAs) — Kenya has DTAs with Germany, France, the United Kingdom, India, Canada, Norway, Denmark, Sweden, Zambia, South Africa, and the United Arab Emirates.

Balance Tax Due: Tax payable minus credits. Balance tax is due on or before the last day of the fourth month following the end of the year of income under Section 12 of the Income Tax Act (Cap. 470). Unpaid balance tax attracts interest at 1% per month under Section 90(3) of the Tax Procedures Act No. 29 of 2015.

Declaration: The return must be signed by an authorised director or the company secretary under Section 52(3) of the Income Tax Act (Cap. 470), confirming that the information is true, correct, and complete to the best of the signatory's knowledge. False declarations attract criminal penalties under Section 97 of the Tax Procedures Act.
