A UAE VAT dispute should begin by identifying the exact FTA decision and the correct procedural stage. A Tax Assessment Review Request, reconsideration and an objection before the Tax Dispute Resolution Committee are different mechanisms with different conditions. ZeroSync supports assessment analysis, evidence organisation, technical arguments and procedural readiness while preserving the taxpayer’s formal rights.
Start by reviewing the assessment notice, audit findings, calculations, penalties and the evidence already provided to the FTA. Depending on the issue, the next route may be a Tax Assessment Review Request, reconsideration or a later TDRC objection. These routes are not interchangeable, so the filing deadline and permitted evidence should be mapped immediately.
A strong dispute file separates two questions: whether the underlying VAT treatment is technically correct and whether the correct procedure is being used to challenge the FTA decision.
The FTA uses specific mechanisms. Tax Assessment Review is an optional review of a tax assessment and related penalties; reconsideration is a separate mechanism for official FTA decisions; and the Tax Dispute Resolution Committee is a later dispute stage administered through the Ministry of Justice.
| Stage | What it addresses | Important distinction |
|---|---|---|
| Tax Assessment Review Request | An FTA Tax Assessment or part of it and related administrative penalties after an audit. | Designed for review based on the audit record, including technical, calculation or audit-procedure issues. |
| Reconsideration | An eligible official decision issued by the FTA. | Can address factual and legal grounds and may include additional supporting evidence where appropriate. |
| TDRC objection | A dispute following the FTA reconsideration stage, subject to the statutory conditions. | Submitted through the Ministry of Justice online objections system, not as another ordinary EmaraTax reconsideration request. |
| Court appeal | Judicial challenge to a TDRC decision where the applicable legal conditions are met. | This is a formal litigation stage and should be handled with the appropriate legal representation. |
The FTA’s Tax Assessment Review mechanism is intended to allow an independent review of a Tax Assessment and related administrative penalties by FTA officials who were not part of the original tax-audit team.
It can be relevant where the business believes there has been an incorrect application of tax legislation or a treaty, a calculation error, a technical error or an issue with the audit procedure. The review focuses on the facts and evidence available during the tax audit.
If the business wants to introduce material information or evidence that was not provided during the tax audit, the Tax Assessment Review mechanism may not be the appropriate route for that new material. Reconsideration may need to be assessed instead.
Check whether taxable supplies, deemed supplies, adjustments and timing were identified and calculated correctly for the relevant tax period.
Review tax invoices, business-use evidence, blocked-input rules, timing and whether the documentation supports the recovery taken.
Test whether the supply met the legal conditions and whether export, transport or other supporting evidence was available during the audit.
Trace the nature of the supply and the basis for the tax treatment used in the VAT return and accounting records.
Reperform the FTA adjustment, reconcile it to filed returns and identify arithmetic, duplication, period-allocation or tax-base issues.
Map information requests, responses, evidence submitted and the sequence of the audit where the dispute concerns the procedure followed.
The FTA’s current Reconsideration Request service applies to official FTA decisions. The current service card states that the request must be raised within 40 business days from the original FTA decision, subject to the extension mechanism in FTA Decision No. 1 of 2025.
The service is completed through EmaraTax, is free of charge, and the FTA states that it may take up to 45 business days to respond to a completed reconsideration request, with a possible extension of the decision period.
40 business days from the original FTA decision under the current FTA service conditions.
Up to 45 business days from receipt of a completed reconsideration request, subject to extension.
General inquiries, complaints and clarifications are not treated as official decisions eligible for reconsideration.
EmaraTax through the taxable person profile and Reconsiderations service.
The FTA’s current reconsideration service states that a reconsideration request regarding a Tax Assessment cannot be submitted while a Tax Assessment Review Request for that assessment is still pending. Reconsideration becomes available after the review decision is issued or the period for the FTA to decide has expired, taking account of any extension.
This sequencing makes the initial route decision important. The business should identify whether the case is best suited to an audit-record review or whether it needs a reconsideration file that introduces additional evidence or grounds.
The FTA says the concerned person may submit directly, as may an appointed registered Tax Agent or Legal Representative. A tax adviser who is not registered as a Tax Agent is not permitted to submit a reconsideration request on another person’s behalf. ZeroSync’s role should therefore be scoped to preparation, analysis and coordination unless the formal representative is eligible to submit.
For reconsideration, the current FTA service card also lists documentary proof supporting the factual and legal grounds and relevant tax advice among the materials that may be attached.
Confirm the exact FTA decision, notification date, tax periods and amounts in dispute.
Reperform the assessment against returns, ledgers, invoices and the audit evidence.
Choose assessment review, reconsideration or later dispute action based on the facts and available evidence.
Prepare the chronology, calculations, documentary evidence and technical arguments in a structured file.
Support the filing-ready package and responses while preserving deadlines and the formal role of the eligible applicant or representative.
The FTA states that a person can dispute a reconsideration decision before the Tax Dispute Resolution Committee. Objections are submitted through the Ministry of Justice online objections system with the required forms and supporting documentation.
The Committee considers the submissions of both sides and, according to the FTA’s current objection information, issues its verdict within 20 business days from submission. It can extend that decision period by another 20 business days where it considers there are reasonable grounds.
The conditions for accepting an objection, payment requirements and any statutory filing deadline should be checked against the current Tax Procedures legislation and Ministry of Justice process for the particular dispute before filing.
TDRC and court proceedings are not simply an extension of ordinary tax-advisory correspondence. Where litigation or legal representation is required, the appropriate authorised legal professionals should be involved.
The team starts from an internal meeting date instead of confirming when the FTA decision was formally notified.
The business prepares an “appeal” without deciding whether the matter belongs in assessment review, reconsideration or TDRC.
Material not presented during the audit is relied upon in an assessment-review request even though the mechanism is audit-record focused.
Legal arguments are prepared before the disputed tax, penalty and transaction populations have been rebuilt and reconciled.
A consultant prepares to submit a reconsideration without checking whether the person is eligible to file on the taxpayer’s behalf.
Strong documents exist but the reviewer is left to guess which invoice, contract or reconciliation supports each ground.
Tax disputes are vulnerable to missed deadlines because several dates can appear in the file: audit meetings, information requests, assessment issue dates, notification dates, review decisions and reconsideration decisions. The procedural calendar should identify which event actually starts each statutory period.
Keep copies of the FTA notification, EmaraTax messages and relevant correspondence. Where a deadline-extension mechanism may be required, the reason for the delay and evidence supporting it should be prepared before the original period expires wherever possible.
| Assessment item | Evidence question | Technical question |
|---|---|---|
| Disallowed input VAT | Which invoice, payment, contract and business-use records were available? | Were the input-tax recovery conditions applied correctly to the transaction and period? |
| Additional output VAT | Which sales, adjustments or deemed-supply facts support the assessed amount? | Was the tax point, value of supply and VAT treatment applied correctly? |
| Zero-rated supply rejected | What export, transport, customer or supply evidence was submitted during the audit? | Were the conditions for zero-rating satisfied for the specific supply? |
| Period allocation | When were invoices, payments, credit notes or adjustments recorded? | Was VAT attributed to the correct tax period? |
| Administrative penalty | Which underlying violation generated the penalty and when? | Does the penalty follow the current legal framework and the assessment outcome? |
This structure prevents a dispute submission from becoming a long narrative that never explains why a particular assessed dirham amount should change.
Number each supporting document and link it to the relevant ground, tax period and assessed amount.
Summarise the audit, FTA requests, taxpayer responses, assessment notification and later procedural events in date order.
Bridge filed VAT returns to the accounting ledger, disputed transaction population and the FTA’s adjustment calculation.
Link each technical ground to the relevant VAT law, executive regulation, FTA clarification, guide or other authoritative source.
State clearly which part of the assessment or decision is disputed and what adjustment the business is asking the reviewer to make.
Confirm who is permitted to submit or represent the taxpayer at the relevant stage before the filing package is finalised.
Assessment review challenges the tax position or audit outcome. Penalty waiver asks for relief under a different framework, while VAT filing and advisory address the underlying ongoing compliance responsibilities.
VAT dispute work is deadline-sensitive. The latest FTA service conditions, Tax Procedures legislation and Ministry of Justice objection process should be checked against the specific decision and notification date before a filing is made.
It is an optional FTA mechanism for reviewing a Tax Assessment or part of it and related administrative penalties. The review is carried out independently from the original audit team and is focused on the assessment, audit evidence and audit procedure.
The FTA’s assessment-review guidance provides a 40-business-day period from notification of the Tax Assessment and related administrative penalties to submit the request, subject to the applicable extension mechanism.
The mechanism is designed around the facts and evidence available during the tax audit. If material new information or evidence was not presented during the audit, reconsideration may be the more appropriate route to assess.
The FTA’s Reconsideration Request service, updated in August 2026, states that the request must be raised within 40 business days from the original FTA decision. A deadline-extension request may be available under FTA Decision No. 1 of 2025.
The current FTA service card states that the Authority may take up to 45 business days to respond after receiving a completed reconsideration request and may extend the period for deciding the request.
No. The FTA states that reconsideration for a Tax Assessment cannot be submitted while a Tax Assessment Review Request for that assessment is still pending. Reconsideration may become available after the review decision or after the FTA decision period expires, including any extension.
The FTA states that the concerned person can submit directly. An appointed registered Tax Agent or Legal Representative may also submit. A tax adviser who is not registered as a Tax Agent cannot submit a reconsideration request on behalf of another person.
Subject to the applicable legal conditions, the dispute can move to the Tax Dispute Resolution Committee through the Ministry of Justice objection process. Later court proceedings may also be available under the relevant rules.
Send us the assessment or FTA decision, notification date, audit correspondence and the amounts in dispute. ZeroSync can help structure the reconciliation, evidence and technical review before the procedural deadline is lost.
