The Biggest Penalty Overhaul Since VAT Was Introduced in 2018
On 9 October 2025, the UAE Cabinet approved Cabinet Decision No. 129 of 2025, published officially on 11 November 2025. It takes effect on 14 April 2026 — just 33 days from now. This is the most significant reform of the UAE’s administrative tax penalty system since the introduction of VAT in 2018.
The decision replaces the penalty framework under Cabinet Decision 108 of 2021 for VAT and Excise Tax. Corporate Tax penalties under Cabinet Decision 75 of 2023 remain technically unchanged but now operate under unified procedural logic. The result: one cohesive penalty system across all federal taxes, aligned with the Tax Procedures Law (Federal Decree-Law No. 28 of 2022).
For businesses that file corporate tax returns and VAT returns, this changes how penalties are calculated for late payment, incorrect returns, voluntary disclosures, record-keeping failures, and audit non-cooperation. Some penalties are dramatically lower. Others are newly introduced. And the window to clean up old errors before the new regime starts is closing fast.
⏰ You Have 33 Days
If you have known errors in past VAT or CT returns, filing a voluntary disclosure before 14 April 2026 means the old penalty rules apply. After that date, the new 1% per month regime kicks in. For long-standing errors, the old rules might cost more. For recent errors, the new rules might cost less. You need to model both scenarios now. Ask Fastlane to check →
Old vs New: The Complete Penalty Comparison
Late Payment of Tax
This is the single biggest change. The old system was notoriously punitive — compounding percentages that could reach 300% of the unpaid amount. The new system is simpler and far more predictable.
| Metric | Old Rules (CD 108/2021) | New Rules (CD 129/2025) |
|---|---|---|
| Immediately after due date | 2% of unpaid tax | 14% p.a. calculated monthly (~1.17%/month) |
| After 7 days | Additional 4% of unpaid tax | Same 14% p.a. continues |
| After 1 month | 1% per day of unpaid tax | Same 14% p.a. continues |
| Maximum cap | 300% of unpaid tax | No compounding — 14% p.a. flat rate |
| 6-month cost on AED 100K unpaid | AED 186,000+ (2%+4%+1%/day×150) | AED 7,000 (14%×100K×6/12) |
| 12-month cost on AED 100K unpaid | AED 300,000 (capped) | AED 14,000 |
Look at those numbers. A business with AED 100,000 in unpaid VAT that went 12 months overdue would have paid AED 300,000 in penalties under the old system — triple the original tax. Under the new system: AED 14,000. That’s a 95% reduction.
This doesn’t mean the FTA is going soft. It means they’re aligning with OECD best practice and making penalties proportional to the offence. The message is clear: pay on time, but if you’re late, the cost is transparent and predictable. Professional VAT filing and corporate tax filing eliminates late payment risk entirely.

Voluntary Disclosure Penalties
Voluntary disclosure — telling the FTA about errors in your returns before they find them — is now dramatically cheaper. The new system directly rewards early self-correction.
| Scenario | Old Penalty (CD 108/2021) | New Penalty (CD 129/2025) |
|---|---|---|
| VD filed before audit notification | Percentage of tax difference (escalating) | 1% per month of tax difference, from due date to VD date |
| VD filed after audit notification | Higher escalating rate | 1% per month + additional 15% fixed penalty |
| Example: AED 50K error, 8 months late | Variable — could reach AED 15,000+ | AED 4,000 (1% × 8 months × AED 50K) |
| Example: AED 100K error, 6 months, VD after audit notice | Variable — AED 25,000+ | AED 21,000 (AED 6K monthly + AED 15K fixed) |
The takeaway: file your voluntary disclosure early. Every month you wait adds 1% of the tax difference. And if you wait until the FTA sends an audit notification, that’s an additional 15% on top. With the FTA conducting 93,000 inspection visits in 2024 (a 135% increase over the prior year), waiting for them to find your error is increasingly risky.
Incorrect Tax Returns
| Violation | Old Penalty | New Penalty (CD 129/2025) |
|---|---|---|
| Incorrect return — first offence | AED 3,000 | AED 500 |
| Incorrect return — repeat within 24 months | AED 5,000 | AED 2,000 |
| Waiver available? | No | Yes — if corrected by due date or VD shows no tax change |
This is excellent news for businesses making honest mistakes. An incorrect VAT return that’s corrected before the deadline incurs zero penalty under the new rules. Even if caught later, the first-offence fine drops from AED 3,000 to AED 500. That said, repeat violations within 24 months still cost AED 2,000 — so getting it right the first time with professional tax filing services remains the most cost-effective approach.
Other Key Penalty Changes
| Violation | Old Penalty | New Penalty (from 14 Apr 2026) |
|---|---|---|
| Failure to maintain records in Arabic | AED 20,000 | AED 5,000 |
| Failure to notify FTA of changes | AED 10,000 – AED 20,000 | AED 1,000 (first); AED 5,000 (repeat) |
| Failure to keep records | AED 10,000 (first); AED 20,000 (repeat) | AED 1,000 (first); AED 20,000 (repeat) |
| Late filing of tax return | AED 1,000 (first); AED 2,000 (repeat) | AED 1,000 (first); AED 2,000 (repeat) — unchanged |
| Failure to facilitate FTA audit | Penalty on taxpayer only | Penalty on taxpayer AND tax agent/legal representative |
| Late CT registration | AED 10,000 | AED 10,000 — unchanged (CD 75/2023) |
Note the new audit cooperation rule: if your tax agent or legal representative fails to cooperate with an FTA audit, they can now be penalised alongside you. This is a significant shift that highlights the importance of working with qualified, FTA-registered professionals like Fastlane’s tax team.
Real Numbers: How This Affects 5 Dubai Businesses
| Business | Issue | Penalty Under Old Rules | Penalty Under New Rules | Savings |
|---|---|---|---|---|
| Ahmed’s trading co | AED 80K VAT paid 4 months late | AED 104,800 | AED 3,733 | AED 101,067 saved |
| Sara’s consultancy | AED 25K CT error, VD filed 6 months after | ~AED 5,000 | AED 1,500 | AED 3,500 saved |
| Raj’s restaurant | Records not in Arabic (first offence) | AED 20,000 | AED 5,000 | AED 15,000 saved |
| Maria’s IT firm | AED 200K VAT unpaid for 12 months | AED 600,000 (capped 300%) | AED 28,000 | AED 572,000 saved |
| Khalid’s startup | Incorrect VAT return (first time) | AED 3,000 | AED 500 (or AED 0 if corrected by deadline) | AED 2,500 saved |
Maria’s case is the most dramatic: AED 572,000 in penalty savings simply because the new system replaces a compounding penalty with a flat annual rate. But notice — the new rules don’t eliminate penalties, they make them proportional. The most cost-effective approach remains: file on time, pay on time, use professionals. At AED 249–999 for CT filing and AED 149–199/quarter for VAT filing, Fastlane’s services cost a fraction of even the new, reduced penalties.
Strategic Question: Should You File a VD Before or After 14 April?
This is the question every tax advisor in Dubai is fielding right now. The answer depends on when the error occurred and how much tax is involved.
| Scenario | File VD Before 14 April? | File VD After 14 April? | Recommendation |
|---|---|---|---|
| Small error discovered recently (1-3 months old) | Old escalating rates apply | New 1% rate = lower cost | Wait until after 14 April |
| Long-standing error (12+ months old) | Old rates may cap lower for short errors | 12+ months × 1% = 12%+ of difference | Model both — often better to file now |
| Large tax difference (AED 100K+) | Depends on duration | 1% × months × AED 100K+ adds up | Get professional advice — stakes are high |
| Error with no tax impact (zero difference) | No VD needed after new rules — correct in next return | No VD needed — correct in next return | Wait — new rules let you self-correct |
One critical improvement: under the new Tax Procedures Law (FDL 17/2025), errors that result in no change to tax payable no longer require a voluntary disclosure. You can simply correct them in your next return. This eliminates a significant administrative burden for businesses dealing with classification or reporting errors that didn’t affect the bottom line.
What Stays the Same: Penalties That Don’t Change
Not everything is getting cheaper. Several core penalties remain unchanged:
Penalties That Remain the Same After 14 April 2026
• Late CT registration: AED 10,000 (under CD 75/2023 — not affected by CD 129)
• Late VAT registration: AED 10,000 (unchanged)
• Late CT/VAT deregistration: AED 1,000/month up to AED 10,000 (unchanged)
• Late filing of return: AED 1,000 first offence, AED 2,000 repeat within 24 months
• Incorrect tax invoices: AED 5,000 per document
• Failure to issue tax invoices: AED 5,000 per transaction
Registration, filing, and invoicing penalties remain firm. The FTA still expects you to register on time (CT registration AED 199), file on time (VAT filing from AED 149), and issue correct invoices. What’s changed is the cost of paying late and correcting errors — not the cost of ignoring your obligations entirely.
Your 33-Day Action Checklist Before 14 April 2026
Audit All Past CT & VAT Returns for Errors
Review every return filed in the last 5 years. Look for misclassified supplies, incorrect input VAT claims, reverse charge errors, and wrong emirate-wise reporting. Request a compliance review →
Model VD Penalties Under Both Regimes
For each identified error, calculate penalties under the current rules AND the new 1%/month rules. File VDs now if the old regime is cheaper, or wait if the new regime saves money.
Pay Any Outstanding Tax Balances
If you owe any unpaid VAT or CT, paying before 14 April means the old penalty rules apply to the period before that date. After 14 April, the 14% p.a. rate kicks in on any remaining balance.
Update Arabic Records
The penalty for not maintaining records in Arabic drops from AED 20,000 to AED 5,000. But why pay even AED 5,000? Ensure all required records have Arabic translations now.
Verify Registration Status
CT registration penalty remains AED 10,000. If you’re not yet registered, do it now: CT registration from AED 199. VAT registration: AED 199.
Engage Professional Filing for All Future Returns
Under the new 24-month repeat window, a second incorrect return costs AED 2,000. Professional CT filing from AED 249 and VAT filing from AED 149/quarter makes errors virtually impossible.
❌ Waiting Until After 14 April Without Preparing
- • Existing errors accumulate 1%/month penalty from original due date
- • FTA audit notification adds 15% fixed penalty on top
- • Tax agents can now be penalised for audit non-cooperation
- • 93,000 FTA inspections in 2024 — audit risk is real
- • Repeat violations within 24 months carry higher penalties
Risk: Cumulative penalties + audit exposure
✅ Getting Compliant with Fastlane Before 14 April
- ✓ Full compliance review of all past CT & VAT returns
- ✓ VD penalty modelling under both regimes
- ✓ VDs filed where beneficial under current rules
- ✓ Outstanding payments resolved before rate change
- ✓ Clean compliance record entering new regime
Cost: AED 249+ CT | AED 149+ VAT | Peace of mind: priceless
The Legal Framework: Where CD 129 Fits
For reference, here’s how Cabinet Decision 129 of 2025 fits into the broader 2026 tax reform landscape:
| Legislation | Effective | What It Does |
|---|---|---|
| FDL 47/2022 (Corporate Tax Law) | June 2023 | 9% CT rate, AED 375K threshold, QFZP rules, SBR |
| CD 75/2023 (CT Penalties) | Aug 2023 | AED 10K late registration, 14% p.a. late payment for CT |
| FDL 16/2025 (VAT amendments) | 1 Jan 2026 | 5-year credit expiry, anti-evasion rules, no RCM self-invoicing |
| FDL 17/2025 (Tax Procedures) | 1 Jan 2026 | Expanded FTA audit powers, 5-year limitation, new VD rules |
| CD 129/2025 (Unified Penalties) | 14 Apr 2026 | New penalty rates for VAT & Excise; harmonised with CT framework |
| MD 243 & 244/2025 (E-Invoicing) | 1 Jul 2026 | Mandatory e-invoicing pilot, then phased rollout |
Every one of these reforms points in the same direction: the FTA is building a tighter, more data-driven enforcement system. The penalty reductions in CD 129 aren’t a sign of leniency — they’re paired with expanded audit powers, real-time e-invoicing data, and stricter documentation requirements. The FTA is making penalties more proportional because they’re becoming better at finding violations. Professional corporate tax filing and VAT filing services are the most reliable way to stay ahead of this evolving system.
