A Complete Guide to KRA eTIMS Compliance for Kenyan Businesses

The Kenya Revenue Authority's electronic Tax Invoice Management System (eTIMS) has changed how businesses issue invoices and report taxes. If you run a business in Kenya — whether it is a duka, salon, hardware store, or restaurant — you need to understand what eTIMS means for you and how to stay compliant.

This guide covers everything: what eTIMS is, who needs it, the penalties for non-compliance, and the easiest way to get set up.

What is KRA eTIMS?

eTIMS is KRA's system for real-time tracking of all business transactions in Kenya. Every time you make a sale, the invoice details are transmitted to KRA electronically. The goal is to close the tax gap by ensuring all business income is properly documented.

Think of it as a digital connection between your business and KRA. Instead of filing returns manually at the end of the month, your transactions are reported as they happen.

Who Needs to Comply with eTIMS in Kenya?

As of 2024, all VAT-registered businesses in Kenya must use eTIMS. But it does not stop there — KRA has been expanding the requirement to include:

All businesses with a KRA PIN
Both VAT-registered and non-VAT businesses
Businesses of all sizes, including small traders and sole proprietors

If you operate a business in Kenya, you should assume that eTIMS applies to you. The cost of non-compliance is far higher than the cost of setting up.

eTIMS Penalties — What Happens If You Do Not Comply?

Non-compliance carries serious consequences:

Penalties and fines — KRA can impose fines for failing to issue electronic invoices
Disallowed expenses — purchases without proper eTIMS invoices cannot be claimed as tax-deductible expenses. This means you pay more tax.
Tax audits — non-compliant businesses are more likely to be flagged for KRA audits
Business disruption — in extreme cases, KRA can issue agency notices or freeze bank accounts
Supplier problems — other businesses may refuse to trade with you if you cannot issue eTIMS-compliant invoices

The message from KRA is clear: comply now or face consequences later.

How Does eTIMS Work? Step by Step

Here is the basic flow:

You make a sale — whether it is a product or service
Your system generates an invoice — with all required details (buyer info, items, tax amounts)
The invoice is sent to KRA — in real-time via the eTIMS API
KRA validates and returns a code — a unique invoice number and QR code
The customer receives a compliant receipt — with the KRA QR code included

This happens in seconds. The customer does not notice any delay.

What You Need for eTIMS Compliance

A KRA PIN

Every business owner should already have this. If you do not, register at the KRA iTax portal (itax.kra.go.ke).

An eTIMS-Enabled System

This is where most businesses get stuck. You have a few options:

KRA's free eTIMS tools — KRA offers a web portal and a simple app, but they are basic and not designed for high-volume businesses
An eTIMS-integrated POS system — the best option for most businesses. Your POS handles sales, inventory, AND eTIMS compliance in one place
Custom integration — for large businesses with existing ERP systems

Internet Connection

Since invoices are transmitted in real-time, you need an internet connection. However, good systems like Sokosuite queue transactions offline and sync when connectivity is restored — so a brief internet drop does not stop your business.

Common eTIMS Mistakes Kenyan Businesses Make

Issuing Manual Receipts Alongside eTIMS

If you issue a handwritten receipt without sending it through eTIMS, that transaction is invisible to KRA. This creates a discrepancy that can trigger an audit. Every sale — no matter how small — must go through your eTIMS-enabled system.

Using Wrong Tax Codes

Different products and services have different tax rates in Kenya. Using the wrong tax code means you are either overcharging or undercharging VAT — both create problems. A good POS system applies the correct tax code automatically based on your product categories.

Delayed Invoice Transmission

Some businesses batch their invoices and send them at the end of the day. eTIMS requires real-time or near-real-time transmission. Delays can be flagged by KRA.

Forgetting Credit Notes for Returns

When you process a return or give a discount after the sale, you need to issue a credit note through eTIMS. Many businesses forget this step, creating discrepancies in their KRA records.

Frequently Asked Questions

Is eTIMS mandatory for all businesses in Kenya?

Yes. KRA has progressively expanded the requirement. As of 2024, all businesses with a KRA PIN — including small traders and non-VAT registered businesses — are expected to comply.

Can I use eTIMS without a computer?

Yes. POS systems like Sokosuite run on any smartphone browser. You can issue eTIMS-compliant invoices from your phone. KRA also offers a basic mobile app, but it lacks inventory and sales tracking features.

What if my internet goes down during a sale?

Good eTIMS-integrated systems have offline mode. The sale goes through normally, the invoice is queued, and it transmits to KRA automatically when connectivity returns. Your business does not stop.

How much does eTIMS compliance cost?

KRA's own tools are free but very basic. A POS system with eTIMS integration like Sokosuite starts at around KES 500/month — and you get sales tracking, inventory management, and financial reports included.

Do I need to issue an eTIMS invoice for M-Pesa payments?

Yes. Every sale requires an eTIMS invoice regardless of payment method — cash, M-Pesa, bank transfer, or credit. The invoice records the sale, not just the payment.
