What happened

The Kenya Revenue Authority (KRA) has announced that its iSCAN platform will be unavailable for a twelve‑hour window on Sunday. The notice, reported by The Star, states that the shutdown is planned to allow system upgrades and essential maintenance. KRA did not provide an exact start‑time, only indicating that the outage will span a twelve‑hour period during the day. The authority urges all taxpayers to complete any pending transactions before the closure. This announcement was made public earlier this week through KRA’s official website and SMS alerts to registered users.

Context and background

iSCAN is KRA’s integrated online portal that handles a wide range of tax and customs functions, including filing of VAT returns, PAYE submissions, and electronic clearance of import documents. Since its launch in 2019, iSCAN has become the primary digital gateway for both large corporations and small‑medium enterprises (SMEs) to meet their tax obligations. The platform is accessed through a secure web portal and a mobile app, allowing users to submit returns, make payments, and track the status of their filings in real time.

The decision to shut down iSCAN for twelve hours reflects a scheduled maintenance cycle that KRA conducts periodically to patch security vulnerabilities, improve system performance, and introduce new features. In recent years, the authority has faced increasing cyber‑threats, prompting a more aggressive upgrade agenda. The upcoming maintenance is therefore positioned as a preventative measure to safeguard taxpayer data and reduce the risk of system failures during peak filing periods.

KRA released the notice on a Monday, giving taxpayers roughly five days to adjust their schedules. The communication was disseminated via multiple channels: an official press release on the KRA website, a bulletin on the iSCAN dashboard, and targeted SMS messages to all registered taxpayers. The agency also posted reminders on its social media accounts, emphasizing that the shutdown will affect all iSCAN services, including the electronic clearance of customs documents.

Historically, KRA has carried out short, often two‑hour, maintenance windows during off‑peak hours. However, the twelve‑hour duration announced for this Sunday is the longest planned outage since the platform’s inception. In 2022, a brief three‑hour interruption was logged during a system upgrade, and a similar four‑hour outage occurred in early 2023. Those earlier incidents were generally resolved without major disruption, but the extended window this time raises concerns for businesses that rely on continuous access.

Compared with what is normal

Under normal circumstances, iSCAN operates 24 hours a day, seven days a week, with an average uptime of 99.5 percent. Maintenance windows are typically scheduled for late night or early morning hours to minimise impact on daily operations. The twelve‑hour shutdown represents a significant deviation from the usual two‑to‑four‑hour maintenance slots that KRA has employed in the past. Moreover, the timing—mid‑day on a Sunday—coincides with a period when many SMEs perform end‑of‑week reconciliations and prepare for the upcoming week’s tax filings.

• Typical uptime: 99.5 % vs. 87 % availability during the twelve‑hour shutdown.
• Usual maintenance: 2‑4 hours, often after midnight; current shutdown: 12 hours on a Sunday.
• Peak usage periods: end of the month and tax deadline weeks; this outage falls just before the first week of the new tax month.
• Alternative channels: KRA’s manual filing offices remain open, but they are limited in capacity and may experience queues.

Why it matters

For Kenyan SMEs, iSCAN is the primary conduit for meeting statutory tax obligations. An unexpected downtime can delay the submission of VAT returns, PAYE filings, and customs clearances, potentially exposing businesses to penalties for late filing. Cash‑flow timing is also affected; businesses that schedule tax payments through iSCAN may need to hold funds longer than planned, impacting working capital.

The shutdown could also ripple through supply chains. Importers who rely on electronic clearance to release goods from ports may face delays, leading to higher demurrage costs and disrupted inventory levels. Exporters, on the other hand, might encounter bottlenecks when trying to obtain export permits, which could affect delivery schedules to overseas buyers. In addition, the reduced processing capacity at KRA’s back‑office during the outage may create a backlog that takes several days to clear once the system is back online.

Practical steps

• Complete all pending iSCAN transactions before the announced shutdown. Prioritise filing of VAT, PAYE, and customs clearance documents that are due within the next week.
• If a filing deadline falls on or shortly after the shutdown, submit the return early or use KRA’s manual filing centres as a backup. Keep copies of any manual submissions for future reference.
• Inform your finance team and any external accountants about the outage so they can adjust their work schedules and avoid planning critical tasks during the downtime.
• Monitor KRA’s official communication channels—website, SMS alerts, and social media—for any changes to the shutdown schedule or unexpected extensions.
