Excise Tax Controversies in the UAE: Where Disputes Start and How to Resolve Them

Summarise with AI

“Excise tax controversy” in the UAE rarely means a public scandal. It means a business on the wrong end of an FTA assessment: a stockpiling declaration the Federal Tax Authority disputes, a product classification that changes the tax rate applied, a deregistration request that gets refused, or a penalty the taxpayer believes is wrong. Federal Decree-Law No. 7 of 2017 on Excise Tax and its executive regulations set the rates. Federal Decree-Law No. 28 of 2022 on Tax Procedures sets how a taxpayer fights back when the FTA gets an assessment wrong. Both matter equally once a dispute starts.

What Actually Triggers an Excise Tax Dispute

Four situations account for most excise tax disputes we see in the UAE market.

• Product classification. Whether a drink is taxed at 50% (carbonated or sweetened) or 100% (energy drink) depends on ingredient composition, not branding. Importers and manufacturers frequently disagree with the FTA’s classification of a specific SKU, and the dispute affects every unit sold, not just one transaction.
• Stockpiling declarations. Under Cabinet Decision No. 52 of 2019, a “stockpiler” holding excise goods above the free zone or normal business threshold on the date a rate changes must declare that stock and account for the tax difference. See our guide to excise tax payment and stockpiling rules for the mechanics. Rate transitions, including the sweetened drinks rate change effective 1 January 2026 (below), create exactly this exposure, and the FTA has queried stockpiling declarations closely around each transition.
• Deregistration refusals. The FTA can refuse or delay excise tax deregistration where outstanding returns, unpaid tax, or an open audit exist. Businesses that stop dealing in excise goods but assume deregistration is a formality are the ones most often caught out.
• Penalty disputes. Late registration, late filing, incorrect returns, and record-keeping failures each carry a fixed administrative penalty. Disagreement over whether the underlying violation occurred, or over penalty stacking, is the single most common reason excise taxpayers file a reconsideration request. Our excise tax penalty guide breaks down the current fixed amounts.

General excise tax liability, registration, and the goods that trigger it are covered in our separate explainer on excise tax liability in the UAE. This article focuses only on what happens once that liability is disputed.

The Rate Framework Behind Most Classification Disputes

Cabinet Decision No. 52 of 2019 sets the baseline rates that still govern most excise goods.

The sweetened drinks change is the biggest classification-driven controversy risk on the market right now. The FTA replaced the flat 50% ad valorem rate with a tiered volumetric charge based on grams of sugar per 100ml, moving the calculation from “value of the drink” to “sugar content of the drink.” Energy drinks are unaffected and remain at a flat 100%. Any business still applying the old flat 50% logic to a reformulated or newly launched sweetened drink is calculating the wrong liability, and that gap surfaces at the next FTA audit, not before.

How an Excise Tax Dispute Actually Runs

Once the FTA issues an assessment or penalty a taxpayer disagrees with, Federal Decree-Law No. 28 of 2022 sets a fixed sequence. Skipping a step, or missing a deadline within it, generally forfeits the right to challenge the amount.

The disputed tax and penalty must be paid in full before a reconsideration request or TDRC objection is admissible. This “pay first, argue after” rule catches businesses that treat a dispute as a reason to withhold payment. It is not. Withholding payment while disputing an assessment adds a separate late-payment penalty on top of the amount already contested.

Worked Example: Voluntary Disclosure Under the Current Penalty Framework

A beverage distributor discovers, three months after filing, that it under-declared AED 40,000 of excise tax on a batch of high-sugar drinks misclassified under the old flat rate instead of the new tiered volumetric charge. Under the administrative penalty framework in Cabinet Decision No. 129 of 2025 (effective 14 April 2026), a voluntary disclosure made before the FTA notifies the business of an audit carries a penalty of 1% of the tax difference per month it remained undisclosed.

Three months of exposure at 1% per month works out to AED 1,200 (3% of AED 40,000), on top of the AED 40,000 in additional tax due. Had the business waited until after the FTA opened an audit to disclose, an additional 15% penalty would apply on top of the monthly rate, a difference of roughly AED 6,000 for the same underlying error. Early voluntary disclosure, not disputing the classification after the fact, is consistently the cheaper route.

Our View: Where to Put Compliance Effort

Most excise tax controversies we see are preventable, not defensible. Businesses that dispute an FTA assessment after the fact are usually disputing a classification or stockpiling position they never documented properly at the time. Our recommendation is to build the documentation before the dispute, not during it:

• Re-test every sweetened and carbonated product against the new sugar-content tiers rather than assuming the old flat rate still applies.
• Keep a dated stock count and tax calculation on file at every rate-change date, even if you conclude no stockpiling declaration is owed.
• File deregistration requests only after confirming all returns are filed and payments cleared, to avoid a refusal that then becomes its own dispute.
• Treat a voluntary disclosure as the default response to a discovered error, not a last resort, given how far the penalty gap has widened under the current framework.

When to Bring In a Tax Dispute Specialist

Handle classification questions and stockpiling declarations internally when the amounts are small and the position is clear. Bring in dedicated tax dispute support once the FTA has issued a formal assessment or penalty, once a reconsideration request deadline is running, or once the dispute is heading to the TDRC, where procedural errors in how the request is filed are a common reason objections fail on technical grounds rather than on the merits.

Frequently Asked Questions

Is excise tax still 50% on all carbonated and sweetened drinks?

Carbonated drinks that are not classified as sweetened remain at the standard 50% rate. Sweetened drinks moved to a tiered volumetric model from 1 January 2026, taxed per litre based on sugar content rather than a flat percentage of value.

Do I have to pay a disputed excise tax assessment before objecting to it?

Yes. Under Federal Decree-Law No. 28 of 2022, the disputed tax and any penalty must be paid before a reconsideration request or TDRC objection is admissible.

How long do I have to file a reconsideration request?

40 business days from the date the FTA notifies you of the decision you are disputing.

Can the FTA refuse my excise tax deregistration?

Yes, where returns are outstanding, tax remains unpaid, or an audit is open. Clear these first to avoid a refusal that becomes a separate dispute.

Is it cheaper to dispute a penalty or disclose the error voluntarily?

If the underlying tax was genuinely under-declared, voluntary disclosure before an audit notice is almost always cheaper than a disputed assessment plus late-payment exposure, given the monthly penalty structure under Cabinet Decision No. 129 of 2025.
