KRA’s 2026 e-Invoice Crackdown: Your Expenses Without ETIMS Receipts Will Become Taxable Income

The Kenya Revenue Authority has now made it official that, beginning January 1st, 2026, every Kenyan taxpayer filing their returns for the year 2025 must ensure that every shilling of income and every shilling of expense in their tax return is supported by an approved eTIMS or TIMS electronic receipt. This means the era of handwritten receipts, verbal agreements, unrecorded purchases, and informal supplier documentation is finally over. To make this easier to understand, imagine explaining to a Grade 3 pupil that whenever they tell their teacher they bought a pencil for class, the teacher now wants to see the receipt, not just hear the story. That is exactly what KRA is doing: it wants to see the receipts for every business expense so it can confirm that it truly happened and that the supplier properly reported that income as well.

This announcement means that if you, as an individual or business, spend money on anything you want to deduct in your income tax return—such as rent, raw materials, salaries, services, repairs, fuel, stationery, or equipment—you must have a valid eTIMS or TIMS receipt for it. Without that receipt, KRA will treat the amount you spent as if you did not spend it at all. For instance, if you say you spent KSh 300,000 on your workshop tools but have no electronic tax invoice, KRA will add that KSh 300,000 back into your income and then tax you on it. This is the same as a teacher saying: “You claim you used your pocket money on books, but you cannot prove it, so we assume you still have the money.”

The new system works by comparing what you submit in your annual return with information from several data sources. These include TIMS/eTIMS supplier invoices, import records from customs, and withholding tax information from both government and private entities. So if you say you earned KSh 1 million in your business, but your eTIMS receipts show KSh 1.7 million, KRA will use the higher number. If you claim you spent KSh 500,000 on repairs but only KSh 100,000 is backed by eTIMS documents, KRA will disallow the remaining KSh 400,000. Think of it like this: if you say you did homework for seven subjects but the teacher sees only two books signed, the teacher will believe only the two you can prove.

For example, imagine a small furniture maker in Gikomba who buys timber from informal suppliers who do not issue electronic invoices. For many years, this carpenter has been able to tell KRA that he spent KSh 100,000 on timber and KSh 40,000 on nails, varnish, and glue. But now, in the new system, if these purchases have no electronic receipts, KRA will say: “We cannot see the expenses in the system, so we assume you made KSh 140,000 more profit than you declared,” and then tax him on the full amount. This is a painful reality for thousands of small traders who rely on the jua kali network, making this change one of the most controversial taxation decisions in recent years.

To a normal Kenyan reading this, the biggest shock is that the rule applies even to people who are not VAT-registered. Before, only VAT businesses were required to issue eTIMS receipts. But now even a mama mboga supplying vegetables to a restaurant, a landlord collecting rent, a freelance photographer, a small welding workshop, or a teacher giving tuition services must follow the electronic receipting rules if their clients need to use those expenses in tax returns. Even if you file your individual annual tax return once a year in June, you must still ensure your expenses have eTIMS receipts.

Let’s break it down with rent, something almost every Kenyan relates to. Suppose you run a small office in Ruaka, paying KSh 30,000 monthly to your landlord. You want to deduct that rent as part of your business expenses. Before, your landlord’s handwritten receipt was enough. But from 2026 onwards, if your landlord does not issue an eTIMS rent receipt that includes your PIN, KRA will reject the KSh 360,000 annual rent expense. That means the KSh 360,000 is treated as profit you didn’t spend, and you will be taxed on every shilling of it.

Imagine another example: a shop owner in Nakuru buys cleaning services for KSh 5,000 weekly. The cleaner comes, sweeps, mops, and dusts, then the shopkeeper pays cash. Before, this was normal. After this KRA directive, the cleaner must issue an electronic tax invoice showing the service provided and the buyer’s PIN. If not, the KSh 260,000 yearly cleaning expense cannot be deducted, and the shopkeeper ends up paying tax on it as extra income.

The system is designed to match information, like joining the dots in a children’s puzzle. If you say you bought goods worth KSh 200,000 from Supplier A, KRA will check Supplier A’s eTIMS system to see if they recorded a sale to you. If the supplier never recorded the sale, your expense will not be accepted. This ensures both sides—the buyer and the seller—report the same transaction. This is KRA’s strategy to reduce cheating, under-reporting, and cash-based tax evasion that has cost the country billions.

Customs records will also be checked. If you imported goods worth KSh 800,000 through the port of Mombasa, KRA will compare your tax declaration with the import data. If you claim KSh 1.2 million, the mismatch will trigger an audit. If you claim KSh 500,000, the system will red-flag your return for under-reporting. Think of customs like the school gate, where everyone is checked. The teacher in class later checks if what the gatekeeper wrote matches what you claim happened outside.

Individuals with side hustles are also affected. If you are a photographer, a tiler, a makeup artist, a DJ, a baker, a tutor, a plumber, or a mechanic, and you want your clients to deduct your payments as business expenses, you must issue eTIMS receipts. If you don’t, your clients may drop you because they cannot use your expenses in their tax returns. So this directive will push thousands of small service providers into formalisation, whether they like it or not.

This rule also affects major sectors like real estate. Landlords will finally be forced to issue proper electronic receipts if their tenants need to claim rent as expenses. Gone are the days when a landlord collected rent in cash and wrote a receipt only when forced. From 2026, any landlord not issuing eTIMS receipts will lose tenants who require compliant documentation for tax deduction.

We must also understand the painful consequences of non-compliance: any unverified expense becomes taxable income. This means if you cannot defend a KSh 1 million expense with a proper eTIMS invoice, your tax liability could increase by 30% of that amount—an extra KSh 300,000 in tax. For many SMEs, this could collapse their business. For families, it could wipe out school fees, rent money, or savings.

The new rules also mean Kenyans must tell their suppliers to upgrade. Whether you buy water for resale, charcoal for your kibanda, beauty products for your salon, car parts for your garage, or stationery for your office, you must ask: “Do you issue eTIMS receipts?” If they don’t, either they must comply or you must drop them. KRA will no longer accept excuses, emotional stories, or explanations of jua kali challenges.

This shift is more than a tax issue—it is a structural transformation of Kenya’s entire supply chain. The directive forces digital records, formal reporting, and transparent invoicing, which benefits long-term economic planning but hurts informal traders who have operated outside structured taxation. This is why it’s controversial: it seems fair on paper but hard on the ground.

The impact on SMEs will be huge. Many small businesses rely on informal suppliers for raw materials because they are cheaper. But cheap without documentation will now become expensive because unverified expenses increase the tax. So businesses must choose between cheaper informal suppliers or more expensive formal suppliers whose eTIMS invoices help in tax reduction.

This may also drive inflation. If suppliers incur costs upgrading systems to meet eTIMS requirements, they may raise prices. If businesses move to more expensive formal suppliers, they may increase product prices. If tax liabilities rise because expenses are disallowed, the higher costs may be passed on to customers. Thus, many will notice bread, milk, snacks, and basic goods becoming more expensive indirectly.

Take, for example, a bakery in Eldoret buying flour, sugar, and butter from wholesalers. If the wholesaler gives electronic receipts, the bakery can deduct all expenses. But if the wholesaler does not, KRA will treat tens of thousands of shillings as income. This means the bakery pays more tax and may raise the price of bread.

Let’s look at the transport industry. If you run a fleet of boda bodas or matatus and pay mechanics and spare-parts suppliers, those suppliers must issue eTIMS receipts. Otherwise, your cost of repairs, tyres, and maintenance cannot be deducted. Transport operators who ignore this may be hit with huge tax bills in 2026.

Even schools, churches, clinics, and NGOs must comply. If they buy goods or services and claim them as expenses, the vendors must issue electronic receipts. Schools paying for repairs, clinics paying for medicine, and NGOs paying for logistics will all need to demand eTIMS receipts or face financial consequences.

This shift will also affect employment expenses indirectly. While salaries are usually supported by payroll records, allowances and reimbursements must have proper documentation. If an employee is reimbursed for travel, fuel, or accommodation, the company must ensure eTIMS receipts exist. Otherwise, KRA may tax the employer and employee.

Another important aspect is withholding tax. If a business withholds tax from payments it makes to service providers, KRA will validate whether the income declared by the service provider matches the withholding records. This closes the gap where some people receive income, pay withholding tax, but under-declare their total earnings.

For small Kenyan businesses that use SACCO loans or microfinance, the new rule means they must keep cleaner, more accurate records. Loan officers may now ask borrowers for eTIMS receipts before approving loans, because tax compliance will reflect business discipline.

The eTIMS requirement will also change how Kenyans negotiate with suppliers. Buyers who insist on electronic receipts will become more powerful in negotiations. Suppliers who refuse may lose customers. This will gradually formalise the economy and push small businesses to adopt digital accounting tools.

Finally, this change means that every Kenyan must now treat tax compliance with the same seriousness as paying electricity bills or buying airtime. It is no longer optional or secondary. If KRA treats your unproven expenses as income, the wise thing is to start collecting electronic receipts today, update your suppliers, and prepare your documentation.

In short, KRA has now made it clear: if your expense has no eTIMS receipt, you should consider it taxable income. The smart Kenyan will act now, fix their documentation, educate their suppliers, and prepare early for the 2026 filing season. The unprepared Kenyan will face penalties, audits, unexpected tax bills, and possibly business collapse. The choice is clear, and the time to prepare is now.
