Short answer: KRA's Finance Act 2026 guidance describes a notice and consideration of the taxpayer's explanation before an electronic-system penalty is applied. Read the provision, period and deadline in the notice, and preserve evidence of any system error. Invoice-related expense validation is a separate issue. Do not calculate your exposure from a generic fine or an older version of the law.
What the Verified 2026 Guidance Establishes
KRA's Finance Act 2026 explanation covers failure to issue an electronic invoice, file electronically or pay electronically. It describes a notice process in which the taxpayer's explanation is considered before the relevant penalty is applied.
The same guidance says system-generated errors may qualify for waiver of penalties or interest, subject to the law. Keep evidence and follow the applicable process; an outage does not automatically cancel a notice or grant a waiver.
Keep Expense Validation Separate from a Penalty
KRA's income-and-expense validation guidance connects tax-return figures with TIMS/eTIMS, withholding and customs records. A purchase invoice, buyer PIN, linked credit and business evidence all need to reconcile where applicable.
Whether an expense is deductible is different from whether a penalty applies. A missing invoice should not be described as an automatic flat 30% charge: the effect depends on the taxpayer, expense and applicable exclusions or exemptions.
Important Exclusions and Exemptions
- ✓Check the transaction categories in KRA's income-and-expense validation guide rather than treating every missing invoice identically.
- ✓Keep the supporting records for any claimed exclusion: an exclusion from eTIMS validation is not permission to omit the underlying business evidence.
- ✓Check the statutory basis and conditions of an exemption against the law applicable to that period.
- ✓A buyer-initiated invoice may apply to an eligible small-supplier transaction; it is not a general replacement for every absent supplier document.
Why Penalty Figures Need a Date and a Legal Basis
Older VAT electronic-invoice material and earlier versions of the Tax Procedures Act describe different provisions. A prosecution offence, an administrative penalty and the tax effect of an unsupported expense should not be combined into one headline number.
An earlier edition of this guide quoted two times the tax due using a July 2025 consolidation. That figure is not presented here as the verified post-2026 rule. Confirm the enacted provision, commencement date and the taxpayer's circumstances before relying on a calculation.
Build an Evidence Pack for the Notice
| Record | What to include | Why it helps |
|---|---|---|
| Notice | Issue date, reference, cited provision, period and response deadline | Identifies the question that needs an answer |
| Affected transaction | Original invoice reference, CU details if returned and exact error | Links the explanation to the actual sale |
| Incident timeline | Attempt times, outage evidence, screenshots and support tickets | Shows what happened and when |
| Recovery | Retry history, accepted receipt or linked credit and correction | Shows the eventual outcome and any remaining uncertainty |
| Reconciliation | Sales, payments and the applicable return workpaper | Explains differences between the records |
What to Do After an eTIMS Compliance Notice
- ✓Read the notice, legal provision, period and response deadline carefully.
- ✓Preserve invoices, KRA responses, outage records, payment evidence and correction attempts.
- ✓Reconcile accepted, pending, failed and duplicated submissions before creating replacement invoices.
- ✓Explain the facts accurately and obtain qualified tax advice where the amount or legal interpretation is material.
- ✓Correct the underlying invoicing or return process instead of relying only on a written response.

Frequently asked questions
Open a question to read the answer.
Can I calculate an eTIMS penalty from an old article?
Use the enacted law applicable to the period and the actual notice. This guide confirms KRA's 2026 notice process but does not claim to have verified the full amended penalty calculation.
Does a system error automatically remove a penalty?
No. KRA says system-generated errors may qualify for waiver subject to the law. Preserve evidence and follow the applicable response process.
Is an expense without an eTIMS invoice always disallowed?
Check the transaction, business evidence and applicable exclusions or exemptions. Do not apply a single conclusion to every expense category.
What should I keep after a failed transmission?
Keep the original invoice reference, exact error, attempt times, support correspondence and eventual acceptance or correction evidence. Reconcile the outcome before issuing a replacement.
