Filing Deadlines Overview
The UAE Federal Tax Authority (FTA) administers three main tax types, each with distinct filing periods and deadlines. Missing any of these deadlines results in automatic penalties — the FTA system generates penalties the day after the due date with no grace period or manual intervention required.
Understanding your compliance calendar is critical for avoiding unnecessary costs. Late filing penalties alone can amount to AED 1,000–10,000 per return, while late payment carries additional fixed penalties plus daily surcharges. For businesses filing monthly or quarterly returns across VAT, Corporate Tax, and Excise Tax, the total number of annual deadlines can exceed 20.

No Grace Period
The FTA does not provide grace periods for late filing or payment. Penalties are automatically applied by the EmaraTax system on the day after the deadline. Weekend and public holiday adjustments are limited — if a deadline falls on a Friday or Saturday, it typically moves to the next business day, but always verify on the FTA portal.
VAT Filing Deadlines
VAT returns must be filed and any VAT due must be paid within 28 days after the end of each tax period. The FTA assigns businesses either monthly or quarterly filing periods based on annual turnover at the time of registration.
Filing Period Assignment
| Annual Turnover | Filing Frequency | Returns Per Year |
|---|---|---|
| Above AED 150 million | Monthly | 12 |
| Below AED 150 million | Quarterly | 4 |

Stagger Period Start Dates
Not all businesses have tax periods starting on January 1. The FTA assigns stagger groups — your quarterly periods may start in any month (e.g., Feb–Apr, May–Jul, etc.). Always check your specific period dates in the EmaraTax portal under your VAT registration details.
Corporate Tax Deadlines
UAE Corporate Tax (CT) was introduced on June 1, 2023, for financial years starting on or after that date. Corporate Tax returns and payments are due within 9 months after the end of the relevant tax period (financial year). There is no separate provisional payment requirement for most businesses.
Key CT Deadlines by Financial Year End
| Financial Year End | CT Return & Payment Due | Tax Registration Due |
|---|---|---|
| December 31, 2024 | September 30, 2025 | Within 3 months of obligation |

What Must Be Filed
- Corporate Tax return via EmaraTax portal (Form CT-1)
- Audited financial statements (if required by your license/activity)
- Transfer Pricing disclosure form (if related party transactions exceed thresholds)
- Tax loss carry-forward schedule (if applicable)
- QFZP election form (for Qualifying Free Zone Persons)
- Small Business Relief election (if eligible, turnover ≤ AED 3 million)
CT Registration Required Even if No Tax Due
All taxable persons must register for Corporate Tax and file a return, even if their taxable income is below AED 375,000 (the 0% bracket) or they qualify for Small Business Relief. Failure to register carries a separate penalty of AED 10,000.
Excise Tax Deadlines
Excise Tax applies to specific goods deemed harmful to health or the environment, including tobacco products (100%), carbonated drinks (50%), energy drinks (100%), sweetened drinks (50%), and electronic smoking devices and liquids (100%). Returns are filed monthly.
Filing Schedule
Excise Tax returns must be filed within 15 days after the end of each tax period (calendar month). Payment is due on the same date as the filing deadline.
| Tax Period | Deadline |
|---|---|
| January 2026 | February 15, 2026 |
| February 2026 | March 15, 2026 |
| March 2026 | April 15, 2026 |
| April 2026 | May 15, 2026 |
| May 2026 | June 15, 2026 |
| June 2026 | July 15, 2026 |
Registration Deadlines
Registration deadlines vary by tax type and are often triggered by business events rather than fixed calendar dates. Failing to register on time carries significant penalties.
| Registration Type | Trigger | Deadline | Late Penalty |
|---|---|---|---|
| VAT Mandatory | Taxable supplies exceed AED 375,000 in 12 months | 30 days from exceeding threshold | AED 10,000 |
| VAT Voluntary | Taxable supplies exceed AED 187,500 (or expenses) | Any time (no penalty for delay) | N/A |
| Corporate Tax | All taxable persons (residents, PEs, certain non-residents) | Within 3 months of tax obligation | AED 10,000 |
| Excise Tax | Producing, importing, or stockpiling excise goods | Before commencing activity | AED 10,000 |
| Tax Group (VAT) | Parent + subsidiaries meeting conditions | 30 days from meeting conditions | AED 10,000 |
| Tax Group (CT) | Parent + subsidiaries forming CT group | With CT return filing | N/A |
VAT Penalties & Fines
The FTA imposes administrative penalties for various VAT violations under Cabinet Decision No. 40 of 2017 (as amended). These penalties are applied automatically and can accumulate quickly if not addressed.
| Violation | Penalty |
|---|---|
| Late VAT registration | AED 10,000 |
| Late filing of VAT return | AED 1,000 (first time), AED 2,000 (repeat within 24 months) |
| Late payment of VAT | 2% immediately + 4% on the 7th day + 1% daily (max 300%) |
| Filing incorrect VAT return | AED 1,000 (first voluntary disclosure), AED 2,000 (second) |
| Failure to issue tax invoice | AED 5,000 per invoice |
| Failure to issue credit note | AED 5,000 per credit note |
| Failure to keep records | AED 10,000 (first), AED 50,000 (repeat) |
| Not displaying TRN on documents | AED 2,500 |
| Not displaying prices inclusive of VAT | AED 15,000 |
| Failure to notify FTA of changes | AED 5,000 (first), AED 15,000 (repeat) |
Late Payment Compounds Rapidly
The late payment penalty structure is particularly aggressive: 2% on the day after the due date, plus 4% on the 7th day, plus 1% daily thereafter up to a maximum of 300% of the unpaid tax. A AED 100,000 liability could accrue over AED 7,000 in penalties within just the first month.
Corporate Tax Penalties
Corporate Tax penalties follow a similar structure to VAT penalties but with some CT-specific additions under the CT penalty regime published by the FTA.
| Violation | Penalty |
|---|---|
| Failure to register for CT | AED 10,000 |
| Late filing of CT return | AED 500 per month (max AED 10,000 per return) |
| Late payment of CT | 14% per annum on outstanding amount |
| Failure to maintain transfer pricing documentation | AED 500,000 |
| Filing incorrect CT return | Based on voluntary disclosure timeline; fixed + percentage penalties |
| Failure to notify FTA of changes | AED 1,000 – 5,000 |
| Failure to maintain records for 7 years | AED 10,000 (first), AED 20,000 (repeat) |
Payment Methods
Tax payments are made through the EmaraTax portal. The FTA accepts several payment methods, each with different processing times that affect when your payment is considered "received."
| Method | Processing Time | Notes |
|---|---|---|
| e-Dirham Card | Instant | Recommended; immediate confirmation |
| Credit/Debit Card | Instant | Visa/Mastercard accepted; processing fees may apply |
| Bank Transfer (GIBAN) | 1–3 business days | Use FTA-assigned GIBAN; allow processing time before deadline |
| e-Debit | 1–2 business days | Direct bank debit; must be set up in advance |
Pay Early for Bank Transfers
If using bank transfer (GIBAN), initiate payment at least 3 business days before the deadline. The FTA considers the payment date as the date funds are received, not the date you initiated the transfer. Late payment penalties apply from the deadline regardless of when you sent the funds.
Calendar Planning Tips
Proactive calendar management is the simplest way to avoid penalties. Here are practical strategies for staying on top of your tax filing obligations:
Set Internal Deadlines 7 Days Early
Create internal deadlines that are one week before the FTA deadline. This provides buffer for unexpected issues, review time, and payment processing delays. Use your accounting software's reminder system.
Automate Recurring Reminders
Set up automated reminders at 30, 14, 7, and 3 days before each deadline. Include reminders for both filing and payment — they are separate actions that both have their own deadlines.
Close Books Monthly
Even if you file quarterly, close your books monthly. This reduces the end-of-quarter rush, catches errors early, and ensures your data is always ready for filing well before the deadline.
Maintain a Master Tax Calendar
Create a single calendar that consolidates all tax deadlines: VAT, CT, Excise, registration renewals, and CT provisional payments. Share it with your finance team and external accountant.
Use UAE TAX AI Tax Calendar
UAE TAX AI automatically tracks all your filing deadlines, sends smart alerts based on your registration details, and shows real-time status of upcoming obligations with color-coded urgency indicators.
Common Mistakes to Avoid
Based on FTA enforcement data and common client experiences, these are the most frequent mistakes that lead to penalties:
Confusing filing and payment deadlines
Both filing and payment must be completed by the deadline. Filing your return on time but paying late still incurs late payment penalties.
Using the wrong tax period
Filing a return for the wrong period (e.g., wrong quarter due to stagger group confusion) is treated as a non-filing for the correct period.
Ignoring nil returns
If you had no taxable transactions in a period, you must still file a nil return. Non-filing penalties apply even when the tax due is zero.
Bank transfer timing
Initiating a bank transfer on the deadline day. Processing takes 1–3 days — the payment is received late even though you initiated it on time.
Not filing CT returns when below the threshold
Even if your taxable income is under AED 375,000, you must file a CT return. Claiming Small Business Relief also requires filing a return with the election.
Forgetting voluntary disclosure corrections
If you discover errors in a previously filed return, you must submit a voluntary disclosure. Undisclosed errors found during FTA audit attract higher penalties than self-reported ones.
Frequently Asked Questions
Can I request an extension from the FTA?
The FTA generally does not grant deadline extensions for VAT filing. For Corporate Tax, extensions may be available in exceptional circumstances, but this requires a formal application before the deadline. Assume no extension will be granted and plan accordingly.
What happens if I overpay VAT?
Overpayments appear as credits on your EmaraTax account. You can offset them against future VAT liabilities or apply for a refund through the portal. Refund processing typically takes 20–45 business days.
Do I need to file a return during the first period after registration?
Yes. Your first return covers the period from your effective date of registration to the end of your first assigned tax period. Even if this is a short period (e.g., 2 weeks), a return must be filed.
Can I change my VAT filing frequency?
You can apply to the FTA to change from quarterly to monthly filing (or vice versa). This requires a formal application through EmaraTax and is subject to FTA approval. Changes typically take effect from the next full tax period.
What is a voluntary disclosure and when do I need one?
A voluntary disclosure is a formal notification to the FTA that a previously filed return contained errors. You must submit one if the error exceeds AED 10,000 in tax impact. Voluntary disclosures attract lower penalties than FTA-discovered errors.
How do I check my deadlines in EmaraTax?
Log in to emaratax.gov.ae, navigate to your tax registration, and view "Obligations" or "Tax Periods." Each period shows the filing deadline and current status. The FTA also sends email and SMS notifications before deadlines.
