Disagree with a KRA assessment? You have rights. This guide covers the full objections and appeals process in Kenya — deadlines, requirements, and strategies that work.
A KRA tax assessment landing in your inbox is not the end of the conversation. It is the beginning of one — and the law is firmly on your side, provided you act within the right windows and use the right arguments.
Every year, thousands of Kenyan businesses and individuals receive assessments that are incorrect: wrong figures, misapplied tax law, inflated penalties, or computations that simply do not reflect reality. Most pay without question — not because the assessment was right, but because they did not know they could push back.
This guide tells you exactly how to push back, what to say, and what to do when KRA disagrees with you.
When Can You Dispute a KRA Assessment?
You can raise a formal objection any time KRA issues an assessment you disagree with. Assessments take several forms, and each is disputable:
Self-assessment disputes arise when KRA reviews your own filed return and raises a query or adjusts the figures upward. You may disagree with the adjustment while accepting the original return.
Estimated assessments occur when KRA raises a tax bill based on its own estimate — typically when returns are unfiled or records are deemed inadequate. These are among the most commonly disputed assessments, and often the most inflated.
Agency assessments arise from audit findings, where a KRA officer reviews your books and raises additional tax based on what they found — or believe they found.
Penalty and interest assessments are standalone bills for late filing, late payment, or other compliance failures. These are disputable separately from the underlying tax.
Amended assessments occur when KRA revisits a previously settled period and issues a revised bill. These can arrive years after the original return was filed.
The common thread: if KRA has issued a formal notice of assessment and you believe it is wrong — in whole or in part — you have the right to object.
The 30-Day Objection Deadline — Non-Negotiable
This is the most critical fact in this entire guide.
Under Section 51 of the Tax Procedures Act, you have 30 days from the date of the assessment notice to file a formal objection. Miss this window and your right to object is extinguished. You cannot revive it by explaining you did not know. You cannot argue it was not a reasonable deadline. The 30 days begins the moment the notice is issued.
In practice this means:
If you receive a KRA assessment notice today, your objection deadline is 30 days from today — not 30 days from when you open it, not 30 days from when you consult an accountant. The clock runs from the assessment date on the notice itself.
What happens if you miss the 30-day window?
You lose your right to object at the KRA level. You can still appeal directly to the Tax Appeals Tribunal, but the Tribunal expects you to have exhausted the internal KRA process first. Arriving at the Tribunal without having filed an objection significantly weakens your position and may result in the Tribunal declining to hear the case.
The only exception: good cause
The Tax Procedures Act permits late objections where the taxpayer can demonstrate “good cause” for the delay. This is a high bar. Ignorance of the deadline does not meet it. Medical incapacitation with documentation might. Postal failure with evidence might. Do not rely on this provision — assume the 30-day rule is absolute.
Practical implication: The moment a KRA assessment arrives — by email, post, or iTax notification — treat that day as Day 1 of 30. Do not file it for later review. Act immediately.
Grounds for Objection
A valid KRA objection is not a general expression of disagreement. It must specify the grounds on which you dispute the assessment. Here are the recognised grounds under Kenyan tax law and practice:
Errors of law
KRA has applied the wrong legal provision to your situation. Examples include:
- Charging VAT on a supply that is exempt or zero-rated under the VAT Act
- Applying the wrong rate of income tax for your business structure or category
- Treating a capital receipt as income
- Disallowing a deduction that is expressly permitted under the Income Tax Act
- Applying a penalty provision that does not apply to your category of taxpayer
Legal errors are the strongest grounds for objection because they are either right or wrong — there is no factual dispute, only a question of which law applies.
Errors of fact
KRA has based the assessment on incorrect facts. Examples include:
- Attributing income to your business that belongs to a different entity
- Using turnover figures that do not match your actual records
- Counting the same transaction twice
- Misreading bank credits as revenue when they are loans, capital injections, or inter-account transfers
- Applying employment tax to payments that are not employment income
Factual errors require you to produce documentary evidence. Bank statements, contracts, invoices, board minutes, and audited accounts are your weapons here.
Incorrect computations
KRA has applied the correct law to roughly correct facts but made arithmetic errors or used the wrong formula. Examples include:
- Applying a penalty percentage to the wrong base figure
- Compounding interest incorrectly
- Using the wrong exchange rate for foreign currency transactions
- Failing to deduct instalment tax payments already made
Computational errors are often the easiest to win because they require no legal or factual argument — just a correct recalculation with supporting documentation.
Procedural grounds
KRA failed to follow its own prescribed procedures before raising the assessment. Examples include:
- Issuing an assessment without the required prior notice or opportunity to respond
- Conducting a field audit without valid authorization
- Raising an assessment outside the statute of limitations (generally 5 years for income tax, 4 years for VAT)
- Issuing an estimated assessment where adequate records were available and were not requested
Procedural grounds are powerful because they attack the validity of the assessment itself, not just its content.
How to Prepare and File a Formal KRA Objection
The objection document — structure and requirements
A KRA objection must be in writing and must satisfy the requirements of Section 51 of the Tax Procedures Act. A poorly drafted objection — one that fails to state specific grounds or provide supporting documentation — may be rejected as invalid, leaving you back at Day 1 with no time remaining.
Here is the structure that works:
Header information
- Your full legal name or company name
- Your PIN (Personal Identification Number)
- Reference to the specific assessment notice (include the assessment number, date, and tax type)
- Your contact details and those of any authorised representative
Statement of the assessment State what KRA has assessed you for: the amount, the tax type, the period, and the due date on the notice.
Grounds of objection — specific and numbered This is the core of the document. For each ground of objection, state:
- The specific aspect of the assessment you dispute
- Why you dispute it (the legal provision, factual error, or computational mistake)
- What the correct position should be
- The documentary evidence that supports your position
Be precise. “We disagree with the assessment” is not a ground of objection. “The assessment includes KSh 480,000 attributed to sales proceeds received in February 2024. These receipts were loan repayments from related party XYZ Ltd, evidenced by the attached loan agreement dated March 2023 and the repayment schedule” is a ground of objection.
Relief sought State the specific outcome you want: full cancellation of the assessment, reduction to a specified amount, or recalculation using specified figures.
Supporting documents Attach everything that supports your grounds. KRA cannot grant relief you have not substantiated. Documents to attach depending on the nature of the dispute:
- Bank statements covering the disputed period
- Invoices, contracts, and purchase orders
- Audited or management accounts
- Payroll records and employee contracts
- Loan agreements and board minutes
- Prior correspondence with KRA on the same matter
- Expert reports or legal opinions if applicable
Filing the objection Objections are filed through the KRA iTax portal under the “Disputes” section, or submitted in writing to the relevant KRA tax station (Domestic Taxes Department). Retain proof of filing — a portal acknowledgement reference or a physically stamped copy. This is your evidence that you filed within the 30-day window.
KRA’s Obligation to Respond — Timelines and What to Do When They Don’t
Once you have filed a valid objection, the ball moves to KRA’s court — but the law gives them a defined window.
Under the Tax Procedures Act, KRA is required to respond to your objection within 60 days of receipt. This response should either allow the objection (fully or partially), reject it, or request additional information. If they request additional information, the 60-day clock pauses while you gather and submit it, then resumes when you respond.
What if KRA does not respond within 60 days?
This is where many taxpayers are unaware of a powerful provision in their favour. If KRA fails to issue a decision within the 60-day window, the objection is deemed to have been allowed by operation of law. In other words, silence from KRA defaults to a win for you.
In practice, you should not simply wait and assume the deemed allowance has taken effect. If Day 60 passes without a KRA decision, immediately write to the Commissioner of Domestic Taxes formally noting that the 60-day window has elapsed and requesting written confirmation that the objection has been allowed. Create a clear paper trail. If KRA then attempts to revive the assessment, you have documented evidence of the deemed outcome.
Monitoring your objection status
Log into the iTax portal regularly during the 60-day period. KRA sometimes issues decisions and correspondence through the portal without separate email notification. Missing a partial-allowance decision because you did not check iTax can cause you to miss the 30-day window to escalate a partially rejected objection to the Tax Appeals Tribunal.
If Your Objection Fails — Escalating to the Tax Appeals Tribunal
If KRA rejects your objection — fully or partially — your next step is the Tax Appeals Tribunal (TAT). The Tribunal is an independent quasi-judicial body established under the Tax Appeals Tribunal Act. It operates separately from KRA and is empowered to hear, consider, and determine any tax dispute.
Filing at the TAT: the second 30-day window
You have 30 days from the date of KRA’s objection decision to file an appeal at the Tax Appeals Tribunal. This is a separate and equally hard 30-day deadline. Missing it extinguishes your right to a TAT hearing for that assessment.
The appeal is filed by lodging a memorandum of appeal with the TAT Registrar. The memorandum must:
- Identify the assessment and KRA decision being appealed
- Set out the grounds of appeal (these can build on or refine your earlier objection grounds)
- State the relief you are seeking
- Be accompanied by the filing fee (currently KSh 20,000 for SMEs; confirm current fees at filing)
What happens at the TAT
Once your appeal is accepted, KRA is served with the appeal documents and given an opportunity to file a statement of response. The Tribunal then schedules a hearing at which both parties — you (or your representative) and KRA — present their evidence and legal arguments.
The Tribunal may:
- Allow the appeal and reduce or cancel the assessment
- Partially allow the appeal
- Dismiss the appeal and uphold KRA’s position
- Refer the matter back to KRA with directions
TAT decisions have historically been favourable to well-prepared taxpayers. Documented hardship, clear factual errors, misapplied law, and procedural failures by KRA have all resulted in assessments being reduced or cancelled. The Tribunal takes its independence from KRA seriously.
TAT hearings in 2026
The Tribunal has increased its capacity since 2024, with hearings now conducted both in Nairobi and in regional centres. Cases are typically heard within 3 to 6 months of filing, though complex multi-year audit disputes can take longer.
After the TAT: High Court appeal
If the Tribunal rules against you and you believe there is a point of law to argue, you may appeal to the High Court (Tax Division) on a point of law only — not on factual findings. High Court appeals are expensive and slow. They are appropriate only for significant sums and clear legal errors in the Tribunal’s decision.
Alternative Dispute Resolution — The Faster Path
Running parallel to the formal objection and appeal pathway is Kenya’s ADR mechanism for tax disputes, introduced under amendments to the Tax Procedures Act and now actively promoted by KRA.
What is ADR in tax disputes?
ADR (Alternative Dispute Resolution) is a structured negotiation process in which a neutral facilitator — typically a KRA-appointed officer with no direct involvement in the original assessment — works with both the taxpayer and the relevant KRA team to reach a negotiated settlement. It is faster than the formal objection process and avoids the adversarial dynamics of a TAT hearing.
When can you access ADR?
ADR can be applied for at any stage:
- Before filing a formal objection (to attempt early settlement)
- After an objection has been filed but before KRA issues its decision
- After a TAT appeal has been filed but before the hearing date
Critically, ADR does not suspend or replace your formal deadlines. If you are in the ADR process and it breaks down, you must still have your formal objection or appeal active. Do not abandon the formal track in favour of ADR and then miss your hard deadlines.
Who benefits most from ADR?
ADR works best when:
- The dispute is primarily factual rather than legal (competing interpretations of the same figures rather than a pure legal argument)
- Both parties have some merit — KRA’s assessment is inflated but not entirely baseless, and you have partial exposure
- Speed matters more than perfect outcome — ADR can resolve a dispute in weeks that would take a year at the TAT
- You want to preserve the relationship with KRA for ongoing compliance purposes
What ADR typically achieves
Negotiated settlements in Kenyan tax ADR commonly land at 40–70% of the original assessment, particularly where the taxpayer has good documentation and a credible factual case. The key to ADR success is not being the loudest voice in the room — it is having the strongest evidence on the table.
Applying for ADR
Submit a written application to the Commissioner of Domestic Taxes requesting ADR for the specific assessment in dispute. Include a brief factual summary of the dispute and the grounds for settlement. KRA will assign a facilitation officer and schedule the first session.
Why Professional Representation Dramatically Changes Outcomes
The gap between represented and unrepresented taxpayers in KRA dispute outcomes is substantial — and it is not because KRA is inherently unfair. It is because tax disputes have procedural, legal, and technical dimensions that the average business owner is not trained to navigate.
Where unrepresented taxpayers lose ground
They miss the 30-day deadline because they did not know it started from the assessment date, not the day they read the letter.
They file an objection that states disagreement without specifying grounds, which KRA rejects as invalid — and they have no days left to refile correctly.
They produce bank statements without the accompanying narrative that explains why the credits shown are not taxable income.
They accept a partial allowance from KRA without realising they can escalate the rejected portion to the TAT within 30 days.
They enter ADR without a realistic sense of what their position is worth, and settle for significantly less than the evidence supports.
What professional representation delivers
A registered tax agent or advocate who handles KRA disputes regularly brings:
- Deadline management — they know every clock that is running and ensure you never miss a window
- Objection drafting that meets the legal standard for validity and specificity
- Evidence framing — presenting documents in the sequence and structure that KRA and the TAT find persuasive
- Knowledge of precedent — which arguments have worked at the TAT and which have not
- KRA relationships — professional agents interact with KRA officers regularly and understand the informal dynamics that influence dispute outcomes
- ADR negotiation experience — knowing what settlements are realistic and when to walk away
When to bring in professional help
If any of the following apply to your situation, do not attempt to handle the dispute alone:
- The assessment exceeds KSh 200,000
- The dispute involves multiple years or multiple tax types simultaneously
- You have received an audit notice alongside the assessment
- KRA is alleging tax evasion or avoidance, not just non-compliance
- The 30-day objection deadline has already passed
- The dispute involves a complex transaction — a property sale, a restructuring, a foreign currency element, or related-party dealings
Your Dispute Checklist: Act Before Day 30
| Action | Timing | Priority |
|---|---|---|
| Confirm the assessment date on the notice | Day 1 | Critical |
| Identify every figure you dispute and why | Days 1–3 | Critical |
| Gather supporting documents | Days 1–7 | Critical |
| Draft the formal objection with specific grounds | Days 3–10 | Critical |
| File via iTax or in writing with proof of delivery | By Day 28 | Critical |
| Consider ADR application if partial resolution is acceptable | Any stage | Optional |
| Monitor iTax for KRA response — 60-day window | Ongoing | Important |
| If KRA rejects: file TAT appeal within 30 days of decision | After KRA decision | Critical |
Key Takeaway
KRA assessments are not final. They are opening positions. The law gives you a structured pathway — formal objection, KRA review, Tax Appeals Tribunal, and ADR — to challenge anything that is wrong. The only irreversible mistake is missing the 30-day objection deadline.
If you have an assessment in front of you right now, today is Day 1 of 30. Everything in this guide is designed to ensure you use those 30 days as effectively as possible.
