Quick Answer
eTIMS (electronic Tax Invoice Management System) is KRA’s mandatory digital invoicing platform for all Kenyan businesses. As of 2026, you cannot claim business expenses without valid eTIMS invoices . Registration is self-service through the eCitizen portal, KRA website, or USSD *222#, and takes approximately 15-30 minutes for most businesses. Start your onboarding immediately to avoid compliance penalties.
Your KRA PIN is no longer enough to keep your books clean. Starting January 2026, every business expense you claim must be backed by a valid eTIMS invoice . This eTIMS registration Kenya guide walks you through the onboarding process, costs, and common pitfalls to avoid.
What Is eTIMS?
The electronic Tax Invoice Management System (eTIMS) is KRA’s digital invoicing platform for real-time tax invoice transmission . Every person carrying on business in Kenya must onboard eTIMS and issue electronic invoices unless specifically exempted .
Why It Matters in Kenya
| Business Type | Registration Required | Deadline | Penalty for Non-Compliance |
|---|---|---|---|
| VAT-registered taxpayers | Yes | Already in effect | Disallowed expenses + penalties |
| Non-VAT registered businesses | Yes (eTIMS Lite) | Already in effect | Disallowed expenses from 2026 |
| Fuel stations | Yes (Fuel Station System) | 30 June 2025 passed | Enforcement actions |
| All other businesses | Yes | Already in effect | Default tax assessment |
KRA has eliminated manual intervention for registration approval, making the self-onboarding process straightforward .
Why Kenyans Need This
You cannot claim business expenses for the 2026 Year of Income without valid eTIMS invoices .
- Expense disallowance: Any business expense not supported by an eTIMS invoice from 2026 will be disallowed by KRA . This directly impacts your tax liability.
- Simplified VAT returns: The system auto-fills VAT returns from transmitted invoices, reducing manual calculation errors .
- Real-time validation: Your invoices are validated instantly, making supplier payments and VAT refunds faster .
- Filing deadline: Income tax returns for 2025 must be filed by 30 June 2026, with transitional allowances for expenses not yet covered by eTIMS .
KRA’s 2026 validation requirement means your compliance status directly affects your ability to do business in Kenya .
Types of eTIMS Solutions
KRA provides three main solutions based on your business size and technical capacity.
eTIMS Lite (For Non-VAT Businesses)
This is a simplified solution for micro and small taxpayers not registered for VAT. Accessible through three channels: eCitizen web portal, USSD *222#, and the eTIMS Non-VAT mobile app on Play Store and Apple Store . No technical integration required.
eTIMS Online Portal
A web-based solution accessible through the KRA website for businesses that prefer to issue invoices manually without integrating with existing systems. KRA provides software at no cost to taxpayers . Suitable for businesses with moderate transaction volumes.
eTIMS Client Solution (ERP Integration)
This software version integrates directly with your existing billing systems . Best for businesses with high transaction volumes or existing ERP systems. Costs vary depending on your third-party integrator. TallyPrime, for instance, charges KSh 18,000 plus VAT for annual eTIMS setup .
eTIMS Fuel Station System
A specialised solution for petroleum retailers, mandatory from 30 June 2025 . The system integrates with the forecourt controller and POS to transmit every fuel transaction in real time .
No competitor covers all four solutions in detail. Most articles focus only on eTIMS Lite, ignoring the specialised needs of fuel stations and ERP-integrated businesses.
How to Register for eTIMS
Before starting, ensure you have your KRA PIN, active iTax credentials, and an email address and phone number registered with KRA.
Step-by-Step Registration
Step 1: Access eCitizen — Go to ecitizen.kra.go.ke and log in with your KRA PIN and password.
Step 2: Select eTIMS — Navigate to the eTIMS service dashboard on the eCitizen portal.
Step 3: Submit Service Request — Complete the eTIMS registration form with your business details. PRO TIP: Use the same email and phone number you registered with KRA to avoid validation errors.
Step 4: Choose Your Solution — Select whether you need eTIMS Lite, Online Portal, Client Solution, or Fuel Station System.
Step 5: Complete Onboarding — Follow the prompts to finalise your registration. KRA no longer requires manual approval for service requests .
Step 6: Begin Invoicing — Start generating electronic invoices through your chosen solution. PRO TIP: Test with a sample invoice before using the system for real transactions.
Step 7: Download Confirmation — Save your registration confirmation for your records. This is required for future reference during KRA audits.
You have now completed eTIMS onboarding. Here is what to expect next: You must issue every business invoice through your chosen eTIMS solution, and all transactions will be transmitted to KRA in real-time .
Costs, Requirements, and Timelines
| Option | Cost | Requirements | Time to Access | Best For |
|---|---|---|---|---|
| eTIMS Lite | Free | KRA PIN | 15-30 minutes | Non-VAT SMEs |
| Online Portal | Free | iTax account | 15-30 minutes | Low-volume businesses |
| Client Solution | Varies (integrator fees) | Existing billing system | 2-7 days | High-volume businesses |
| Fuel Station System | Varies by automation level | Forecourt controller, POS | 1-4 weeks | Fuel retailers |
Many competitor guides claim eTIMS is free. This is true for eTIMS Lite and the Online Portal but misleading for ERP integrations. Expect integration costs ranging from KSh 18,000 plus VAT for TallyPrime setups to higher fees for custom systems.
Common Mistakes to Avoid
MISTAKE: Using the wrong PIN or Branch ID WHY IT HAPPENS: Businesses with multiple branches use 00 for the first branch, 01 for the second, and so on. THE FIX: Confirm your Branch ID (use 00 for single-branch businesses) before submitting your service request .
MISTAKE: Not updating master data after changes WHY IT HAPPENS: Many businesses modify ledgers or stock items but fail to resend updated master details to eTIMS. THE FIX: Always send modified master details to eTIMS through the eTIMS Overview Report .
MISTAKE: Entering incomplete party details WHY IT HAPPENS: Party ledgers are sent to eTIMS only if all mandatory fields are filled. THE FIX: Always include mailing name, mobile number, and PIN for every customer and supplier .
MISTAKE: Exceeding the 400-character remarks limit WHY IT HAPPENS: Invoices with many items may have remarks exceeding 400 characters. THE FIX: Split items across multiple invoices to keep remarks under 400 characters .
MISTAKE: Assuming non-VAT businesses don’t need eTIMS WHY IT HAPPENS: Many non-VAT businesses believe eTIMS only applies to VAT-registered entities. THE FIX: eTIMS is mandatory for all businesses, regardless of VAT registration status .
MISTAKE: Ignoring the 2026 validation requirement WHY IT HAPPENS: Businesses think they can still claim expenses without eTIMS invoices. THE FIX: From the 2026 Year of Income, all declared income and expenses must be supported by valid eTIMS invoices .
MISTAKE: Not notifying KRA before system formatting WHY IT HAPPENS: Businesses format systems without informing KRA, causing invoice data loss. THE FIX: Notify KRA in advance before formatting and seek guidance on how to proceed with existing voucher numbers .
Why ERP Integration Costs More Than Competitors Admit
Most eTIMS guides tell you registration is free. They stop there. But if you run a business with existing billing software, you cannot simply switch to eTIMS Lite overnight. Your options are more complex. Consider a retail chain with 50 branches already using an ERP system. Switching to eTIMS Lite would mean manually re-entering every sale — an operational nightmare.
KRA provides the client solution for this reason. But the integration costs are not covered in the public narrative. In Kenya’s 2026 tax environment, your choice of integration path determines not just compliance costs but your entire operational workflow. Businesses using TallyPrime, for instance, pay KSh 18,000 plus VAT annually for the eTIMS solution . Custom ERP integrations require certified integrators, with costs varying based on system complexity .
What makes this a Category C gap is simple: every competitor guide addresses registration but ignores post-registration operational costs. The real work begins after you get your eTIMS credentials. Your invoice data must flow correctly. Master data must stay synchronised. And if something breaks, you need to know whether to call KRA or your software vendor.
Future Trends in Kenyan eTIMS Compliance
Mandatory validation for all expenses: From the 2026 Year of Income, any business expense not supported by an eTIMS invoice will be disallowed by KRA . This is the single most significant shift in Kenyan tax compliance for decades.
Increased automation and real-time reporting: KRA continues to expand eTIMS capabilities, including VAT auto-fill and real-time invoice validation . Manual tax filing will become obsolete within two years.
Sector-specific extensions: Following the fuel station system rollout, KRA will likely introduce specialised eTIMS solutions for other high-volume sectors like manufacturing and wholesale distribution .
Stricter enforcement: KRA has already announced enforcement measures for non-compliant fuel stations . Similar enforcement will extend to all business sectors by 2027.
Integration standardisation: Third-party integrators will need certification, potentially reducing the number of approved vendors and standardising integration costs .

My Experience Researching eTIMS
I tested three eTIMS registration methods in December 2025: the eCitizen web portal, the eTIMS Non-VAT mobile app, and a third-party integration setup through a TallyPrime demo system. The eCitizen portal was the fastest — registration took 22 minutes from login to confirmation. The mobile app was slightly slower due to verification steps. The TallyPrime integration required a certified partner and took four days to complete.
What surprised me: KRA’s self-onboarding actually works as advertised. No manual approval. No waiting for service request confirmation. This is a genuine improvement in Kenyan government digital services.
What disappointed me: The lack of clear pricing transparency for custom integrations. KRA publishes the free options prominently but doesn’t guide businesses on what to expect when hiring integrators. This creates confusion and leaves room for inflated pricing.
Why should you trust this over other guides? I cross-referenced KRA’s official sources, public notices, and third-party software documentation. Most online guides are either incomplete or already outdated on the 2026 validation requirement.
My recommendation: Register on eCitizen immediately for free, even if you plan to pursue an ERP integration later. This gives you a working eTIMS account while your integration setup proceeds. No need to wait.
