The UAE’s penalty landscape for corporate tax, VAT, and excise tax is changing permanently on 14 April 2026. Cabinet Decision No. 129 of 2025 – issued by the UAE Cabinet in October 2025 – replaces the previous penalty framework with a unified, simpler, and in many ways fairer system. But “fairer” does not mean more lenient across the board: the new regime also removes ambiguity, closes loopholes, and makes it far easier for the Federal Tax Authority (FTA) to enforce consistently.

If your business operates in the UAE, this deadline is not one to monitor passively. The transition window is your last real opportunity to identify outstanding errors, file voluntary disclosures under the new rules, and put compliance controls in place before the enforcement clock resets.

This article breaks down every key change, what it costs in dirhams if you get it wrong, and what you should do before April 14.

What Is Cabinet Decision No. 129 of 2025?

Issued on 9 October 2025 and published on 11 November 2025, Cabinet Decision No. 129 of 2025 replaces Cabinet Decision No. 108 of 2021 as the governing framework for administrative penalties across UAE federal taxes. It comes into effect on 14 April 2026 – with no extension or grace period announced.

The decision covers violations of the Tax Procedures Law, the VAT Law, and the Excise Tax Law. Corporate Tax penalties under Cabinet Decision No. 75 of 2023 remain separately governed but operate under the same procedural definitions and philosophy – meaning the spirit of the reform applies across the board.

Three core objectives drive the reform:

• Simplification – replacing compounding penalty structures with clear, flat or time-based rates
• Proportionality – reducing fines for minor administrative errors while maintaining firm penalties for substantive non-compliance
• Voluntary compliance – structuring penalties so that self-correction is always significantly cheaper than being caught in an audit

The Biggest Changes You Need to Know

1. Late Payment: Fixed at 14% Per Annum, No Compounding

One of the most significant structural changes is the replacement of complex, compounding late payment charges with a single, non-compounding rate of 14% per annum calculated monthly on the outstanding tax balance.

This applies consistently across Corporate Tax, VAT, and Excise Tax. If you owe AED 100,000 in corporate tax and pay six months late, the late payment charge is exactly:

AED 100,000 × 14% ÷ 12 months × 6 = AED 7,000

Under the old compounding model, that same delay could have accumulated significantly more. The new structure is predictable – which means there is no longer any ambiguity to exploit or negotiate around. The FTA calculates it, you pay it.

Crucially, there is no cap. The 14% interest keeps accruing until the full amount is settled. A two-year delay on a AED 500,000 liability would cost AED 140,000 in late payment charges alone – before any other penalties apply. Need help staying on top of payment deadlines?

2. Late Filing: AED 500 Per Month, Rising to AED 1,000

Failure to file your corporate tax return on time now attracts a penalty of AED 500 per month for the first 12 months, rising to AED 1,000 per month from the 13th month onwards – with no cap.

This applies to every registered entity, including those with zero taxable income, businesses claiming Small Business Relief, and free zone companies on the 0% rate. The FTA treats non-filing as a violation even when no tax is owed.

A company that files 18 months late accumulates: AED 500 × 12 + AED 1,000 × 6 = AED 12,000 in filing penalties alone, in addition to any late payment interest on the tax owed.

3. Incorrect Tax Returns: Lower First-Time Fine, But Repeat Violations Cost More

The penalty for submitting an incorrect tax return has been restructured to distinguish clearly between first-time mistakes and repeat behaviour:

• First violation: AED 500 (reduced from higher amounts under the previous regime)
• Repeat violation within 24 months: AED 2,000
• Penalty waived entirely if the error is corrected by the original filing due date, or if a voluntary disclosure is submitted and no additional tax is owed

The waiver condition is important. If your accountant catches an error and the filing deadline has not yet passed, you can correct it at no cost. After that window closes, the penalty clock starts.

4. Record-Keeping Violations

The FTA’s requirements for record maintenance remain strict. Under the new regime:

• Failure to maintain records: AED 10,000 for first offence; AED 20,000 for repeat violation within 24 months
• Failure to maintain records in Arabic (where required): reduced from AED 20,000 to AED 5,000 – one of the more notable reductions in the new framework
• Failure to issue a tax invoice or credit note within the legally specified timeframe: AED 2,500 per detected case

During an FTA audit, every missing invoice, incomplete bank reconciliation, or gap in inventory records can trigger a separate penalty. Individual amounts look small – but audits typically flag multiple violations simultaneously, and they add up fast. Our accounting and bookkeeping service ensures your records meet FTA standards year-round, not just when an audit notice arrives.

5. Late Registration: AED 10,000 – and It Hasn’t Changed

The penalty for failing to register for corporate tax on time remains AED 10,000. This is one of the areas the new decision did not reduce, which signals clearly that the FTA treats registration discipline as non-negotiable.

However, there is a waiver mechanism: if you file your first corporate tax return (or annual declaration, for exempt entities) within seven months of your first tax period ending, the AED 10,000 is refunded to your tax account. If it has already been paid, the refund goes back automatically. This applies regardless of whether the business had already registered or not.

6. Failure to Notify Changes: Tiered First and Repeat Penalties

Failing to notify the FTA of changes to your business – changes in address, legal structure, ownership, or taxable activity – now attracts:

• First breach: AED 1,000
• Repeat breach: AED 5,000

Many businesses underestimate this obligation, particularly when restructuring or expanding. If your company has recently undergone changes, verify your FTA registration details are current. Our business advisory team routinely handles FTA notification updates as part of corporate restructuring engagements.

7. Obstructing an FTA Audit

This is a new and significant addition to the penalty framework. The new regime explicitly extends liability to tax agents and legal representatives who fail to cooperate during an FTA audit – not just the taxpayer. If your appointed tax agent obstructs or fails to facilitate an inspection, they can face penalties independently.

This change has real implications for how businesses structure their compliance relationships. Your tax advisor needs to be genuinely audit-ready, not just a filing service.

Voluntary Disclosure: Your Most Powerful Tool – Use It Before the Audit Notice Arrives

The reformed voluntary disclosure (VD) framework is where Cabinet Decision No. 129 of 2025 sends its clearest message: the UAE wants businesses to self-correct errors proactively, and it is willing to make that financially worthwhile.

Under the new structure, VD penalties work as follows:

• VD filed before FTA audit notice: 1% per month (or part thereof) of the unpaid tax difference, calculated from the original return due date to the date the VD is submitted
• VD filed after audit notice: 15% fixed penalty on the underpaid amount, plus 1% per month from the original due date

The gap between these two outcomes is enormous. Consider a business that underreported AED 100,000 in corporate taxable income (tax owed: AED 9,000 at the 9% rate):

• VD filed 8 months after the return due date: 1% × 8 × AED 9,000 = AED 720
• FTA discovers the same error in an audit: 15% × AED 9,000 = AED 1,350 fixed penalty, plus AED 720 in monthly interest = AED 2,070 total

That example is relatively small. For a business with a AED 1 million tax understatement, the difference between proactive VD and audit discovery can be tens of thousands of dirhams. The FTA’s intent is clear: reward early self-correction, make waiting costly.

It is also worth noting that a VD must be filed within 20 business days of discovering the error. Missing that window does not eliminate the VD option, but it can complicate your position if the FTA initiates an inquiry in the interim.

If you suspect your previous filings may contain errors – in corporate tax, VAT, or excise – speak to our advisory team before April 14. We review historic returns, quantify VD exposure, and manage the EmaraTax submission process on your behalf. This is also directly relevant to businesses with related-party transactions: our transfer pricing specialists assess whether historical intercompany pricing is defensible before an audit query forces your hand.

What This Means for Free Zone Businesses

Free zone entities – including those claiming the 0% qualifying income rate – are not exempt from these penalties. All registered taxable persons must file a corporate tax return every year, elect any reliefs they wish to claim, and maintain records meeting FTA standards.

The common misconception that “we don’t pay tax so we don’t need to comply with the full CT framework” is a compliance risk, not a planning position. Free zone businesses face exactly the same filing penalties for late or missed returns as mainland companies. If you’re unsure whether your free zone structure qualifies for preferential rates or how to maintain that qualification going forward, our corporate tax advisory team can walk you through the substance requirements and filing obligations.

What the FTA Is Watching: Audit Triggers in 2026

The FTA conducted 93,000 inspection visits in 2024 – a 135% increase year-on-year – powered by data analytics and cross-tax verification. The same digital infrastructure now covers corporate tax. Understanding what triggers audit selection is part of penalty prevention.

Common red flags include:

• Discrepancies between corporate tax returns and VAT filings (revenue figures that don’t reconcile)
• Sharp profit swings without clear business justification
• Consistent losses when comparable businesses in the same sector are profitable
• Large or unusual refund claims
• Related-party transactions that fall outside the interquartile range in a benchmarking analysis
• Frequent voluntary disclosures (which can indicate systemic compliance weaknesses)

Businesses that treat corporate tax and VAT as separate compliance exercises – without reconciling them to each other – are creating exactly the kind of inconsistencies that trigger FTA review.

Your April 14 Pre-Deadline Checklist

Use the weeks before April 14, 2026 to take the following steps:

1. Audit your historic CT and VAT returns – identify any errors, underreported income, or overclaimed deductions across all filed periods
2. Quantify your VD exposure – calculate the 1% monthly cost of filing a VD now versus the risk of an FTA audit finding the same error later
3. Check your records are complete – 7-year retention is mandatory; missing invoices from 2020 or 2021 are still auditable
4. Verify your FTA registration details – any changes in business structure, address, or ownership must be notified to avoid the AED 1,000–5,000 notification penalty
5. Reconcile your CT and VAT numbers – ensure revenue, input tax, and output tax figures are consistent across both sets of filings
6. Brief your finance team – everyone handling tax filings should understand the new voluntary disclosure process and timelines under the updated regime
