Millions of Kenyans will have to adjust their tax compliance calendars after the Kenya Revenue Authority (KRA) moved the annual income tax return filing deadline from June 30 to April 30, effective January 1, 2027.

The change, introduced under the Finance Act 2026, means individual taxpayers will have four months after the end of the year of income to submit their returns, instead of the previous six months.

The first returns affected will cover income earned between January and December 2026 and must be filed by April 30, 2027.

The revised deadline affects individuals, including salaried employees, self-employed Kenyans and other taxpayers required to submit personal income tax returns. Partnerships are also covered under the revised filing framework.

Previously, taxpayers had until the end of June to declare income earned during the preceding calendar year. The two-month reduction means employees and business owners will need to organise their records earlier to avoid missing the deadline.

KRA says the change is intended to improve tax administration and give the authority more time to review submissions, validate taxpayer information and manage compliance.

However, the new timeline does not apply to every taxpayer. Companies and other non-individual taxpayers will continue filing their returns by the last day of the sixth month after the end of their accounting period. For companies with a December year-end, the deadline remains June 30.

Taxpayers should also take note of the separate timeline reported for nil returns. Individuals with no income to declare are expected to file by January 31 following the end of the year of income, making it important to establish which filing category applies to their circumstances.

Late filing penalties remain a concern under the new arrangement. Individual taxpayers who miss the applicable deadline face a penalty of five per cent of the tax due or KSh2,000, whichever is higher.

The earlier deadline also means taxpayers should not wait until the final weeks to reconcile their income records. Employees should obtain their P9 forms, while people earning income from businesses, consultancy, farming or other activities should maintain supporting records and declare income from all relevant sources.

KRA has indicated that it is preparing changes to its filing systems, including a move towards web-based returns rather than the traditional downloadable Excel format.

The authority has also said it may issue pre-populated returns, although taxpayers will still need to review the information and correct any omissions or errors before submission.

The change marks a significant shift in Kenya's annual tax calendar. For individual taxpayers, April 30 will replace the long-established June 30 deadline, making early preparation increasingly important.
