UAE tax calendar in one paragraph. CT registration — per FTA Decision 3 of 2024 schedule, by licence issuance month, with an AED 10,000 flat penalty for lateness. CT return & payment — within 9 months of financial year end, AED 500/month late-filing (then AED 1,000/month after 12 months), plus 14% annualised late-payment on unpaid tax. VAT return & payment — within 28 days of tax period end (quarterly or monthly), AED 1,000 first offence / AED 2,000 repeat, plus 2% immediate + 4% monthly late-payment from day 7. Voluntary Disclosure above AED 10,000: tiered penalty from 5% + 1%/month (within 1 year) rising to 40% + 1%/month (over 4 years). CbCR 12 months, ESR 6/12 months, UBO 15 days from change. Record keeping 7 years for CT, 5 years VAT (15 years for real estate).
⚠ The worry we hear most
“I think our CT registration is late. My licence was issued in June 2024 and I didn’t know about the deadlines. If I register now, is the penalty just the AED 10,000, or does it compound? Does it affect my ability to elect Small Business Relief? And if I file my first return late on top, how do the penalties stack?”
The short answer: yes, it compounds — the AED 10,000 registration penalty is flat and one-off, but your first CT return deadline sits 9 months after your first financial year end, and if you miss that too you accrue AED 500/month plus 14% annualised late payment. SBR eligibility is unaffected by the registration lateness itself. The right move is to register and file immediately, then consider a Voluntary Disclosure if any numbers are already wrong.
1. The UAE tax compliance timeline at a glance
The diagram below is the compliance calendar for a UAE-resident company with a 31 December financial year end. Dates shift proportionately for other year ends — the structure is the same.
Timeline for a UAE-resident company with 31 December year end. VAT dots are quarterly return deadlines (28 days after period end). CT return and payment are both due 9 months after financial year end. CbCR notification is due 12 months after year end; the report follows 12 months later again.
What this means for you. Your biggest two UAE tax dates each year are four quarterly VAT 28-day deadlines and the CT return/payment at 9 months after year end. For a 31 Dec year end, that puts CT at 30 September. Set calendar reminders at 6 months before and 1 month before both — the 1-month warning catches the "we need accounts audited for QFZP" realisation while there’s still time.
2. UAE Corporate Tax — deadlines and penalties
CT registration deadline schedule
Per FTA Decision No. 3 of 2024, UAE Corporate Tax registration deadlines are set by the issuance month of your trade licence. Miss the deadline and the penalty is AED 10,000 flat (Cabinet Decision 75 of 2023).
| Trade licence issuance month | CT registration deadline |
|---|---|
| 1 January – 29 February | 31 May 2024 |
| 1 March – 30 April | 30 June 2024 |
| 1 – 31 May | 31 July 2024 |
| 1 – 30 June | 31 August 2024 |
| 1 July – 31 August | 30 September 2024 |
| 1 September – 31 October | 31 October 2024 |
| 1 November – 31 December | 30 November 2024 |
| Licence issued in or after 2024 (new entities) | Within 3 months of licence issuance |
| UAE branch of foreign company (new) | Within 9 months of branch registration |
| Natural person — business income | 31 March of the year following the Gregorian year in which AED 1m business turnover was first crossed |
CT return & payment deadlines
Both the annual CT return and the final CT payment are due within 9 months of the end of the relevant financial year. There is no payments-on-account mechanism for CT — it is a single annual payment on the same date as the return.
| Financial year end | CT return & payment due |
|---|---|
| 31 March 2024 (short first period for Jun-23 start) | 31 December 2024 |
| 30 June 2024 (first CT period for June year-ends) | 31 March 2025 |
| 30 September 2024 | 30 June 2025 |
| 31 December 2024 | 30 September 2025 |
| 31 March 2025 | 31 December 2025 |
| 30 June 2025 | 31 March 2026 |
| 31 December 2025 | 30 September 2026 |
CT penalties
| Breach | Penalty | Source |
|---|---|---|
| Late CT registration | AED 10,000 flat | CD 75/2023 |
| Late CT return (first 12 months) | AED 500 per month | CD 75/2023 |
| Late CT return (after 12 months) | AED 1,000 per month | CD 75/2023 |
| Late CT payment | 14% annualised on unpaid balance | CD 75/2023 |
| Submitting incorrect return (FTA-detected) | 50% of tax amount + 4%/month | CD 10/2024 |
| Voluntary Disclosure — within 1 year | 5% + 1% per month | CD 10/2024 |
| Voluntary Disclosure — 1 to 2 years | 10% + 1% per month | CD 10/2024 |
| Voluntary Disclosure — 2 to 3 years | 20% + 1% per month | CD 10/2024 |
| Voluntary Disclosure — 3 to 4 years | 30% + 1% per month | CD 10/2024 |
| Voluntary Disclosure — over 4 years | 40% + 1% per month | CD 10/2024 |
What this means for you. The AED 10,000 CT registration penalty is one-off and non-escalating — so if you’re already late, register today rather than tomorrow and no incremental damage is done beyond that flat sum. By contrast, the AED 500/month late-filing penalty on the return does escalate month by month, and the 14% late-payment runs continuously — so your return deadline is the one to protect first.
Worked example — late CT return 15 months after deadline, AED 100,000 of tax
A UAE Free Zone LLC with 31 December 2024 financial year end should have filed its CT return and paid AED 100,000 of CT by 30 September 2025. It actually files 15 months late, in December 2026.
| Component | Calculation | AED |
|---|---|---|
| Late-filing (months 1-12) | 12 × AED 500 | 6,000 |
| Late-filing (months 13-15) | 3 × AED 1,000 | 3,000 |
| Late-payment interest | 14% × 100,000 × 15/12 | 17,500 |
| Total penalties on top of CT | 26,500 | |
| Total cash to FTA | CT + penalties | 126,500 |
On a 15-month lateness, penalties add 26.5% to the original tax bill. If the FTA detects the under-declaration rather than you filing late voluntarily, the base 50% error penalty + 4% monthly compounds to a figure materially larger — around AED 110,000 of penalties on the same AED 100,000 of CT, more than doubling the total.

3. UAE VAT — deadlines and penalties
VAT deadlines are set by the FTA at registration based on your tax period assignment. Most SMEs get quarterly periods, larger taxpayers monthly.
| Obligation | Deadline | Penalty for breach |
|---|---|---|
| Mandatory VAT registration | Within 30 days of exceeding AED 375k rolling 12-month taxable supplies | AED 10,000 flat |
| Mandatory VAT deregistration | Within 20 business days of qualifying event | AED 10,000 flat |
| VAT return & payment | Within 28 days of end of tax period | AED 1,000 first offence; AED 2,000 repeat within 24 months |
| Late VAT payment | Same as return | 2% immediately + 4% monthly from day 7 |
| Failure to keep records | 5 years (15 years real estate) | AED 10,000 first / AED 20,000 repeat |
| Failure to issue tax invoice | On supply | AED 2,500 per document |
| Failure to display VAT-inclusive prices (B2C) | At time of display | AED 5,000 flat |
| Submitting incorrect return (FTA-detected) | On FTA audit | 50% of tax + 4%/month |
| Voluntary Disclosure (VAT211) | Within 20 business days of becoming aware | Same tiered scale as CT (5% to 40% + 1%/month) |
Worked example — VAT return 3 months late, AED 48,000 of VAT due
| Component | Calculation | AED |
|---|---|---|
| Late-filing (first offence) | Flat | 1,000 |
| Late-payment (day 0 to day 6) | 2% × 48,000 | 960 |
| Late-payment (3 months at 4% / month after day 7) | 3 × 4% × 48,000 | 5,760 |
| Total penalties | 7,720 |
A 3-month VAT lateness on AED 48k costs almost AED 8k in penalties — a 16% uplift. Six months late, the uplift becomes 29%. The 4% monthly late-payment is the main cost and runs compounding until payment lands.
4. Excise, TP, CbCR, ESR, UBO & trade licence
| Obligation | Deadline | Penalty for breach |
|---|---|---|
| Excise Tax return | Monthly, within 15 days of end of month | AED 1,000 / AED 2,000 (repeat) + late-payment % |
| Related-party transactions schedule (in CT return) | Same as CT return (9 months after FYE) | Non-filing: TP adjustment risk + 50% penalty |
| Local File / Master File | Not submitted; provide within 30 days of FTA request | Non-production: AED 50,000-100,000 + TP risk |
| CbCR notification | Last day of fiscal year | AED 50,000 flat |
| CbCR filing | Within 12 months of financial year end | AED 100,000 flat |
| Pillar Two QDMTT return | Within 15 months of fiscal year end (18 months in year 1) | Being finalised in subsidiary legislation |
| ESR notification (where still applicable) | Within 6 months of financial year end | AED 20,000 |
| ESR report | Within 12 months of financial year end | AED 50,000 first / 400,000 repeat |
| UBO change notification | Within 15 days of change | AED 50,000 first / 100,000 repeat |
| UBO annual confirmation | With trade licence renewal | Up to AED 100,000 |
| Trade licence renewal | Annually before expiry | Escalating fines; licence suspension after grace period |
5. Voluntary Disclosure — the single biggest penalty-saver
Across both CT and VAT, the Voluntary Disclosure mechanism (FTA form VAT211 for VAT; equivalent process for CT) is the single biggest penalty saver available. The tiered schedule rewards early disclosure — and penalises every month of delay.
| Lag between original return and VD | Base penalty | Monthly uplift |
|---|---|---|
| Within 1 year | 5% | + 1% per month |
| 1-2 years | 10% | + 1% per month |
| 2-3 years | 20% | + 1% per month |
| 3-4 years | 30% | + 1% per month |
| Over 4 years | 40% | + 1% per month |
| Comparison — FTA-detected error | 50% | + 4% per month |
What this means for you. If you’ve just realised an error above AED 10,000, the clock is 20 business days to file a Voluntary Disclosure. Even if you’re at the 2-3 year tier (20% + 1%/month), you’re saving 30 percentage points of base penalty and 3 percentage points of monthly uplift vs waiting for the FTA to find it. On a AED 100,000 under-declaration 30 months old, that’s a saving of around AED 42,000 of penalties.
6. Record keeping — the retention schedule
| Record type | Retention period |
|---|---|
| UAE Corporate Tax records | 7 years |
| UAE VAT records | 5 years (15 years for real estate) |
| Excise Tax records | 5 years |
| Transfer Pricing documentation | 7 years (CT records) |
| AML / KYC records | 5 years |
| Audited financial statements (QFZP) | 7 years |
| Payroll & WPS records | 2 years (MoHRE) / 5 years (recommended) |
7. The seven deadline mistakes we see most
⚠ The seven deadline mistakes we see most on live client files
- Thinking the 9-month CT deadline resets each year. It doesn’t. It’s 9 months from your financial year end, every year, same date. Set the calendar once.
- Ignoring the CT registration deadline because “we’re dormant.” Mandatory for every UAE-resident juridical person. AED 10,000 flat. Dormant companies get hit every year.
- VAT return filed on day 29. The deadline is day 28, not month-end. The one-day miss is still an AED 1,000 first-offence penalty.
- Letting the AED 10,000 VAT correction threshold catch you out. Any correction above AED 10,000 is Voluntary Disclosure, not next-return rollover. Mis-rolling triggers FTA-detected 50% penalty rather than the much lower VD rate.
- Missing the CbCR notification for a UAE sub of an in-scope MNE group. AED 50,000 flat per missed notification. Set at the UAE constituent entity level even where the group files CbCR in the UPE jurisdiction.
- Thinking UBO is a one-off at incorporation. Changes within 15 days, annual confirmation at licence renewal, every change (new shareholder, 1% stake movement) triggers the clock.
- Running Voluntary Disclosure after 4 years when the FTA has already queried. Once the FTA has formally opened an audit on the period, the VD route may close — it becomes FTA-detected at 50% + 4%/month. The window matters.

Can I file a Voluntary Disclosure for an error I spotted in a return filed 5 years ago?
Does the 14% late-payment interest on CT compound or simple-interest?
What happens if I pay CT but file the return late?
Does the FTA accept “we didn’t know” as a reason to waive a penalty?
How are penalties collected?

If my year end changes, when is my CT return due?
What to do next
Three practical next steps:
- Build your UAE tax compliance calendar. Pull your financial year end and licence issuance month, then populate every date in this guide against your diary. Set 6-month and 1-month reminders on each.
- Spot-check for anything already late. If a return is already missed, the 20-business-day Voluntary Disclosure clock starts the moment you realise. Act within that window.
- If a penalty has landed, consider Reconsideration. 40 business days from the FTA notification. Our UAE CT service and UAE VAT service both handle Reconsideration as a fixed-fee one-off.
