Corporate Income Tax in Kenya sits at 30 percent for both resident companies and non-resident companies operating through a local branch, administered entirely through the Kenya Revenue Authority. Companies pay this tax in four quarterly instalments throughout their financial year, with annual returns due six months after the year closes.
Understanding exactly how this tax is calculated, what deductions you can claim, and when payments are due can save your business from costly penalties. Here is the complete breakdown.
Tax Rates by Company Type
Resident companies pay 30 percent on taxable profits accrued or derived from Kenya, the standard rate that applies to most locally incorporated businesses. Non-resident companies trading through a local permanent establishment also pay 30 percent on their trading profits, but face an additional 15 percent on any profit repatriated back to their branch headquarters abroad.
Companies operating within Special Economic Zones enjoy a preferential rate of 10 percent for their first 10 years, rising to 15 percent for the following 10 years. Export Processing Zone companies get an even more favourable structure, paying 0 percent for their first decade before moving to 25 percent for the next 10 years. These incentives are designed to attract manufacturing and export-oriented investment into designated economic zones.
How Your Tax Liability Is Calculated
KRA calculates taxable profit using a straightforward formula: taxable profit equals gross income minus allowable expenses. Your tax liability is then simply your taxable profit multiplied by the applicable tax rate.
Allowable expenses must be wholly and exclusively incurred in the production of income to qualify as deductions. This includes employee wages, rent, advertising costs, and other genuine operational expenses. Expenses that are not directly tied to generating business income, or that are personal in nature, cannot be deducted and will be disallowed if flagged during a KRA audit.
When Corporate Tax Payments Are Due
Quarterly instalment tax payments are due by the 20th of the 4th, 6th, 9th, and 12th months of your company’s financial year. For a company operating on a standard calendar year, that means payments fall in April, June, September, and December.
Annual final returns and any outstanding tax balance are due within six months of your financial year ending. A company operating on a calendar year, for example, must file its final annual return by June 30 of the following year.
What Happens if You File Late
Late filing carries a penalty of KES 20,000 or 5 percent of the tax due, whichever amount is higher. On top of that penalty, outstanding amounts accrue interest at 1 percent per month until settled in full.
These penalties compound quickly. A company that delays filing for several months can end up owing significantly more than the original tax liability once penalties and accumulated interest are factored in, making timely filing one of the most straightforward ways to protect your business’s cash flow.
Filing Through iTax
All corporate tax filing and payment processes in Kenya are conducted digitally through the iTax Portal. Companies need to maintain accurate financial records throughout the year to ensure smooth filing when quarterly and annual deadlines arrive.

Planning Ahead for Your Tax Obligations
Corporate tax is one of the more predictable obligations Kenyan businesses face, given the fixed quarterly schedule and standard rate structure. Building your instalment payments into your cash flow planning from the start of your financial year, rather than scrambling to find funds as each deadline approaches, is the most effective way to stay compliant without disrupting your operations.
Working with a qualified accountant to accurately track allowable deductions throughout the year also ensures your taxable profit calculation is both compliant and optimised, reducing your overall tax burden within the boundaries of what KRA permits.
