Cabinet Secretary John Mbadi confirms that nil filers, salary earners and business owners will no longer share the June 30 deadline — here is how the new KRA tax returns system works and what it means for every Kenyan taxpayer..
National Treasury Revives Nil Returns Weeks After KRA Scrapped Them
In a development that has caught many Kenyan taxpayers off guard, the National Treasury has moved to revive the filing of nil returns — just weeks after the Kenya Revenue Authority (KRA) appeared to eliminate the requirement entirely through the introduction of its new "PIN with No Obligation" (PWO) category. The reversal signals a significant shift in the government's approach to tax compliance administration and comes with equally significant implications for the millions of Kenyans who fall into the nil returns category each year.
Treasury Cabinet Secretary John Mbadi made the announcement on Thursday, June 4, 2026, during an X Space session — one of the increasingly popular live audio conversations on the social media platform where senior government officials have been engaging directly with Kenyan citizens on pressing policy matters. Speaking candidly and in considerable detail, Mbadi confirmed that nil returns are back, that they will carry a new and earlier filing deadline, and that the broader tax returns landscape in Kenya is about to look very different from what taxpayers have been accustomed to under the existing system.
The revival of nil returns is being packaged as part of a sweeping new staggered returns filing framework designed to address one of the most persistent and frustrating features of Kenya's annual tax compliance cycle: the last-minute rush to the iTax platform that has consistently overwhelmed the system and left thousands of law-abiding taxpayers facing penalties for circumstances entirely beyond their control.
The Problem With the Current System: iTax Congestion, System Failures and Unfair Penalties
To appreciate why the Treasury is introducing a staggered filing approach, it is important to first understand the scale of the dysfunction that has characterised Kenya's existing tax returns system — particularly in the weeks immediately preceding the June 30 annual deadline.
Under the current framework, all categories of taxpayers — whether they are filing nil returns, declaring employment income, or submitting complex business returns — are required to meet the same single deadline of June 30 each year. The result is entirely predictable: a massive and simultaneous surge in traffic to the KRA's iTax online platform in the final days of June, as millions of Kenyans who have procrastinated throughout the year scramble to submit their returns before midnight on the last day.
The consequences of this annual peak-period surge have been deeply damaging to both taxpayer confidence and compliance outcomes. The iTax system has repeatedly buckled under the weight of simultaneous user activity during the June rush, experiencing slowdowns, crashes, and extended periods of unavailability at precisely the moment when the highest number of taxpayers need to access it. When the system fails and taxpayers are unable to submit their returns on time through no fault of their own, the existing legal framework has continued to impose late submission penalties — a deeply unjust outcome that CS Mbadi specifically highlighted as one of the key drivers behind the push for reform.
"We have therefore decided to stagger filing so that nil filers file immediately after December 2025, salary earners file between January and April, while business people still retain the 30th of June deadline," the CS stated, encapsulating the new framework in clear and accessible terms.
How the New Staggered KRA Tax Returns System Works: Three Categories, Three Deadlines
The centrepiece of the Treasury's new approach is the introduction of a categorised, staggered filing system that assigns different return submission periods to different groups of taxpayers based on their income and tax obligation status. Rather than one universal deadline that creates a system-breaking bottleneck every June, there will now be three distinct filing windows — each calibrated to the specific circumstances and complexity of the taxpayer group it covers.
Nil Filers — File Immediately After December Each Year
The first and earliest category under the new system covers nil filers — individuals who are registered with KRA and hold a Personal Identification Number (PIN) but have no taxable income to declare in a given year. Under the new framework, nil filers will be required to submit their returns immediately after December each year, making their filing window the earliest of the three categories.
This is a significant change from the status quo, where nil filers and active income earners all shared the June 30 deadline. By moving nil filers to a December/early January window, the Treasury effectively removes the largest single category of non-income-earning taxpayers from the June peak period entirely — substantially reducing the volume of simultaneous traffic that has historically overwhelmed the iTax platform in the run-up to the mid-year deadline.
Salary Earners — File Between January and April
The second category covers employed individuals who earn a salary and whose income tax is typically deducted at source through the Pay As You Earn (PAYE) mechanism. Under the new staggered system, salary earners will be required to file their annual returns between January and April — giving them a four-month window that runs through the first third of each year and keeps them entirely separate from the June business returns rush.
For the vast majority of formally employed Kenyans whose tax affairs are relatively straightforward — consisting primarily of employment income, any applicable reliefs, and PAYE deductions — the January to April window provides a generous and manageable filing period that eliminates any legitimate reason for last-minute submissions or system-related delays.
Business Owners and Commercial Taxpayers — Retain the June 30 Deadline
The third and final category covers business owners, self-employed individuals, and all other taxpayers engaged in commercial activities whose tax affairs are typically more complex and who may require the full financial year plus additional months to compile accurate accounts and supporting documentation. This group will retain the existing June 30 filing deadline, preserving the structure that the business and accounting community has built its compliance processes around while benefiting from the significant reduction in iTax traffic that the departure of nil filers and salary earners from the June window will deliver.
What the New Tax Filing System Means for Every Kenyan Taxpayer
For the average Kenyan taxpayer, the transition to a staggered filing system carries a mix of immediate practical implications and longer-term compliance considerations that deserve careful attention.
The most immediate impact will be felt by nil filers, who need to understand that their filing obligation has not been eliminated — it has been moved. Rather than waiting until the middle of the year to submit a nil return, this category of taxpayer will now need to file shortly after the close of December each year, meaning the compliance window arrives significantly earlier than most nil filers have historically been accustomed to. Failure to comply with the new earlier deadline could expose nil filers to the same kinds of late submission penalties that the staggered system is ostensibly designed to reduce — making awareness of the new timeline critically important.
Salary earners have the most straightforward transition to navigate: their filing window shifts from the universal June 30 deadline to a January to April period, giving them a clearly defined four-month window at the start of each year to submit employment income returns. Employers and payroll administrators should also take note of the new timeline, as it may affect the scheduling of tax documentation and PAYE reconciliation processes.
For business owners and commercial taxpayers, the June 30 deadline remains unchanged — but the reduced system congestion that should result from the departure of nil filers and salary earners from the June window is expected to translate into a noticeably smoother and more reliable iTax filing experience during what has historically been the most stressful period of the annual compliance calendar.
