Tax Dispute Resolution Services in the UAE
XFLEX supports businesses reviewing Federal Tax Authority decisions, tax assessments and administrative penalties. We help identify the appropriate procedural stage, analyse the tax and accounting position, and organise evidence within a clearly agreed professional scope.
Structured Support for UAE Tax Disputes
A tax dispute may arise when a business disagrees with an official FTA decision, assessment or administrative penalty. The appropriate response depends on the decision received, its notification date, the taxes and periods involved, and whether a review or reconsideration has already been requested.
XFLEX helps examine the relevant records, calculations and correspondence before the next step is selected. Tax advisory, submission by an appointed Registered Tax Agent, accounting support and legal representation have different professional scopes. Those responsibilities are confirmed for each engagement.
For an explanation of the available routes, read how to challenge an FTA tax decision in the UAE. If the matter began with an audit notice, see what to do after receiving an FTA audit notification.

Understanding the Main Tax Dispute Stages
Tax Assessment Review
An eligible person may request review of a tax assessment or part of it and related administrative penalties. Under Article 28(2), the reasoned request must be filed within 40 business days from notification of the tax assessment and related administrative penalties, subject to an applicable extension. This filing deadline is separate from the reconsideration deadline.
The FTA has 40 business days from receiving the review request to issue its decision and 5 business days from issuance to notify the applicant, subject to applicable extensions. Under Article 28(5), assessment review cannot be requested or continued once reconsideration has been filed for the same assessment.
FTA Reconsideration
A reasoned reconsideration request concerning an official FTA decision must generally be filed within 40 business days from notification of that decision. Under the Tax Procedures Law, the FTA has 40 business days from receiving the request to issue its reasoned decision, followed by 5 business days from issuance to notify the applicant, subject to an applicable extension. The FTA service page describes up to 45 business days to respond to a completed request. These decision and notification periods should be distinguished when tracking the case.
Objection Before the Tax Disputes Resolution Committee
Under Article 32 of the Tax Procedures Law, an objection to the FTA's reconsideration decision must generally be submitted within 40 business days from notification. The objection will not be accepted if reconsideration was not previously requested, if the tax connected with the objection has not been paid in full, or if the objection is filed outside the applicable period. Article 32 does not make advance payment of the related administrative penalties a condition for admitting the committee objection.
The AED 100,000 TDRC Finality Rule
Under Article 33(3), the committee's decision on an objection is final where the total Due Tax and Administrative Penalties relating to that decision does not exceed AED 100,000. This includes a total of exactly AED 100,000. The threshold concerns the combined amount, rather than tax alone or each penalty separately.
Where the total exceeds AED 100,000, a court appeal may be available under Articles 34 and 36, subject to admissibility requirements, within 40 business days from notification of the committee's decision. Decisions above this threshold become executory instruments if no appeal is filed within the prescribed period. Any special procedures must also be considered.
Subsequent Court Appeal
A later appeal before the competent court has separate admissibility requirements. Article 36 requires proof of full payment of the tax and settlement of at least 50% of the administrative penalties determined under the committee's decision or the court's ruling, as applicable. The penalty requirement may be met through payment to the FTA or an approved bank guarantee in its favour. The applicable law, any amending decision and the circumstances of the case must be checked before filing.

Frequently Asked Questions About UAE Tax Disputes
What is the filing deadline for a Tax Assessment Review?
A reasoned request must be filed within 40 business days from notification of the tax assessment and related administrative penalties, under Article 28(2), subject to an applicable extension. Assessment review cannot be requested or continued once reconsideration has been filed for the same assessment.
When is a TDRC decision final under the AED 100,000 rule?
Under Article 33(3), the decision on an objection is final if the total Due Tax and Administrative Penalties relating to that decision does not exceed AED 100,000, including a total of exactly AED 100,000. Above that threshold, the availability, conditions and deadline of a court appeal must be considered under Articles 34 and 36 and any applicable special procedures.
Can every FTA communication be reconsidered?
No. Reconsideration concerns an official FTA decision relating to the applicant. General enquiries, complaints and clarifications are not automatically eligible decisions.
What is the deadline for a reconsideration request?
It must generally be submitted within 40 business days from notification of the original FTA decision, subject to any applicable extension.
Who can submit a reconsideration request?
The concerned person may submit directly. An appointed Registered Tax Agent or legal representative may also submit where authorised. A tax adviser who is not a Registered Tax Agent cannot submit on another person's behalf in that capacity.
What must be paid before a TDRC objection?
Article 32 requires full payment of the tax connected with the objection. It does not list advance payment of the related administrative penalties as a condition for admitting the committee objection.
Are payment requirements different for a court appeal?
Yes. A subsequent court appeal requires proof of full tax payment and settlement of at least 50% of the relevant administrative penalties, either by payment to the FTA or an approved bank guarantee, as provided in Article 36.
Does XFLEX provide legal representation in court?
XFLEX provides tax and accounting analysis and evidence support within the agreed scope. Legal advice and court representation are matters for separately authorised legal counsel.
Is a successful outcome guaranteed?
No. The outcome depends on the procedure, applicable law, facts, evidence and decision of the competent authority or court.
