Receiving a tax assessment from the Kenya Revenue Authority can be alarming. The amount may be far higher than you expected, and it often includes penalties and interest on top of the tax. But an assessment is not the end of the road. Kenyan law gives every taxpayer the right to challenge an assessment they believe is wrong. This process is called a tax objection.

Handled well, an objection can reduce or cancel the assessment. Handled poorly, or filed late, it can fail on technical grounds before KRA even looks at the facts. This guide walks through the objection process step by step.

What Is a Tax Objection?

A tax objection is a formal challenge to a tax decision made by the Commissioner. The process is set out in the Tax Procedures Act, 2015. You can object to an assessment and to certain other tax decisions. The objection is filed with KRA, which must then review it and issue a decision.

The objection is the first formal step in any tax dispute. If it does not resolve the matter, you can then appeal to the Tax Appeals Tribunal.

Step 1: Read the Assessment Carefully

Before doing anything else, read the assessment notice in full. Note:

The date of the notice
The tax type and period
The amount of tax, penalties, and interest
The reasons KRA gives for the assessment
Any calculations or schedules attached

Understanding exactly what KRA is claiming, and why, is the foundation of a good objection.

Step 2: Note the Deadline

Under the Tax Procedures Act, an objection must generally be lodged within 30 days of the date you received notice of the decision. This deadline is strict.

If you miss it, you can apply to the Commissioner for permission to file late. You will need to show that you could not file in time for a good reason, such as illness or being away from Kenya, and that you did not unreasonably delay. Approval is not guaranteed, so do not rely on it.

Step 3: Gather Your Evidence

An objection is only as strong as the evidence behind it. Collect everything that supports your position:

Invoices and receipts
Bank statements
Contracts and agreements
Payroll records
Import and export documents
Financial statements and ledgers
Correspondence with KRA, customers, or suppliers
Any expert reports or valuations

Under Kenyan tax law, the burden of proof is on the taxpayer. That means you must show that the assessment is wrong. Simply saying you disagree is not enough.

Step 4: Pay the Undisputed Tax

If part of the assessment is correct, you must pay that part, or reach an arrangement with KRA to pay it, before your objection is treated as valid. Many objections are rejected because the taxpayer did not deal with the undisputed amount.

Step 5: Write the Objection

A valid objection must meet the requirements of the law. In practice, it should:

State precisely the grounds of objection. Explain clearly which parts of the assessment you dispute and why.
State the changes you want. Say what the correct figures should be.
Give reasons for those changes. Link each point to the law and to the facts.
Attach all relevant documents. Include the evidence that supports each ground.

Be organized. Deal with each issue in turn, using headings that match KRA’s assessment. Avoid vague statements and emotional language. Stick to facts, figures, and law.

Step 6: File Through iTax

Objections are lodged through iTax. You will fill in the objection form and upload your supporting letter and documents. Keep the acknowledgment receipt as proof of the date you filed.

Step 7: Respond to KRA’s Review

After filing, KRA reviews the objection. If it finds the objection invalid, for example because required information is missing, it should notify you within the time set by law so you can fix the problem. KRA may also ask for more documents or invite you to a meeting. Respond promptly and keep records of everything you send.

Step 8: The Objection Decision

KRA must make a decision on a valid objection within 60 days. The decision can:

Allow the objection in full
Allow it in part and change the assessment
Reject it and confirm the assessment

If KRA does not make a decision within the 60 days, the objection is treated as allowed under the law. This is a strong protection for taxpayers, which is why proving the date of a valid objection matters so much.

The decision should give reasons. Read it closely, because it forms the basis of any appeal.

Step 9: Decide Whether to Appeal

If you are not satisfied with the objection decision, you can appeal to the Tax Appeals Tribunal. The notice of appeal must be filed within 30 days of receiving the objection decision. The Tribunal is independent of KRA and hears both sides before deciding.

Common Reasons Objections Fail

Filed after the 30-day deadline
Grounds not clearly stated
No supporting documents
Undisputed tax not paid
Arguments based on opinion rather than evidence
Failing to respond to KRA requests during review

Can You Settle Instead?

KRA also offers Alternative Dispute Resolution (ADR) for some disputes. ADR allows the taxpayer and KRA to discuss the issues and try to reach agreement without a formal hearing. It can be faster and less costly. Whether it is the right path depends on the case.

Why Professional Help Matters

An objection is a legal document. It must meet strict requirements, set out arguments clearly, and be supported by evidence. Mistakes at this stage can affect the whole dispute, including any later appeal. Working with advisers who handle tax disputes regularly gives you the best chance of a fair result.

Final Thoughts

A KRA assessment is a decision, not a verdict. You have the right to object, and the law sets out clear steps for doing so. Act quickly, respect the deadlines, gather strong evidence, pay any undisputed tax, and present your case clearly. A well-prepared objection is often the fastest and least costly way to resolve a tax dispute.
