Kenyan taxpayers may soon be required to submit annual income tax returns within four months instead of the current six, under proposed reforms contained in the Finance Bill 2026 aimed at accelerating government revenue collection.
The Bill seeks to move the filing deadline to the final day of the fourth month after the close of a taxpayer’s year of income. Taxpayers with no payable tax would also be compelled to submit nil returns within one month after the end of the year.
If adopted, Kenya would impose a shorter filing period than Uganda, where taxpayers still enjoy a six-month window, though it would remain behind Rwanda, where returns are typically filed within three months after the financial year ends.
The revised timelines appear intended to give the Kenya Revenue Authority (KRA) earlier insight into taxpayer obligations while speeding up inflows into the Exchequer.
The proposed changes could substantially tighten compliance timelines for businesses. At present, companies have up to six months after the close of their financial year to complete audits, compute taxes and file returns.
For firms operating on December year-ends, April would become particularly demanding. Besides handling first instalment tax payments, businesses would also be expected to complete annual tax calculations, file returns and clear any outstanding liabilities within the same month.

The Bill further proposes a major shift in how filing obligations are triggered. Currently, taxpayers only become obligated to file returns after receiving a notice from the Commissioner, with at least 30 days granted for compliance.
Under the proposed framework, that notice-based approach would be scrapped entirely and replaced with an automatic statutory deadline linked directly to a taxpayer’s financial year, irrespective of whether the KRA issues a notice. The move would effectively create a more self-enforcing tax regime where filing obligations arise automatically under the law rather than through administrative action.
The proposals come amid mounting pressure on the National Treasury to boost revenue collection, as the KRA continues grappling with missed collection targets ahead of the government’s June financial year-end.
If approved by Parliament, the amendments to the Income Tax Act would come into force in January 2027.
