Most guidance on the FTA voluntary disclosure UAE 2026 rules is still describing a penalty scale that no longer exists. Cabinet Decision No. 129 of 2025 rewrote the administrative penalty tables for VAT and Excise Tax, and it took effect on 14 April 2026. The stepped 5% to 40% charge that used to sit on a VAT voluntary disclosure is gone, replaced by 1% a month. That single change moves the deadline that matters from a calendar year to a calendar month, and most free zone finance teams have not adjusted for it.
This guide sets out what the law now says: when a disclosure is compulsory rather than optional, the AED 10,000 line that decides whether you file a form at all, the twenty business days you get, what “Form 211” actually refers to, and what the new arithmetic costs on a real number. It is general information rather than advice on your own position; a registered tax agent should confirm how any of it applies to your company.
A Voluntary Disclosure is compulsory in three situations and optional in two
Article 10 of Federal Decree-Law No. 28 of 2022 on Tax Procedures, as amended by Federal Decree-Law No. 17 of 2024, splits the duty into two halves. Three clauses say shall:
- Clause 1. A Tax Return you filed, or a Tax Assessment the FTA issued, understated the Payable Tax. You must disclose.
- Clause 2. A refund application overstated the refund you were entitled to. You must disclose.
- Clause 5. You find an error or omission in a filed return where there is no difference at all in the Due Tax. You must still correct it by submitting a Voluntary Disclosure.
Two clauses say may. Under clause 3, where the error means you paid too much tax, and under clause 4, where you claimed too little refund, disclosure is your choice. That asymmetry is the whole design: errors in the Authority’s favour are voluntary, errors in yours are not.
Clause 5 is the one that catches free zone companies. A misclassified supply that nets to the same VAT figure, a wrong Designated Zone treatment that washes out, a box on the return populated from the wrong ledger — none of them changes what you owe, and all of them are still a mandatory correction under the current text.
AED 10,000 decides whether you file a form or fix it in the next return
Article 10 of Cabinet Decision No. 74 of 2023, the Executive Regulation, turns the duty into a procedure and puts a threshold in the middle of it.
| Size of the understated tax | What the Executive Regulation requires |
|---|---|
| More than AED 10,000 | Submit a Voluntary Disclosure within 20 business days of becoming aware of the error. |
| AED 10,000 or less, and you file returns | Correct it in the return for the period in which you found the error, or in a return not yet due for an earlier period — whichever comes first. No separate disclosure. |
| AED 10,000 or less, and there is no return to correct it in | Submit a Voluntary Disclosure within 20 business days. |
| Refund application overstated | 20 business days from becoming aware, unless the cause was an incorrect return or assessment, in which case the rules above apply instead. |
Two practical points follow. The threshold is measured on the tax difference, not on the size of the transaction, so a large misposting with a small VAT consequence stays inside the self-correction route. And the second row is not an option you elect — where a return is available, that is the required channel, and filing a disclosure instead is the wrong form.
Twenty business days runs from awareness, and awareness is a fact you can be asked to prove
The clock in Article 10(1)(a) starts on “the date when the Taxable Person became aware of the error”, not on the date of the error, not on the return’s due date and not on the date the disclosure is prepared. Business days exclude weekends and public holidays, so the window is roughly a calendar month.
Awareness is the weak point in most files. If a reconciliation, an auditor’s memo or an internal email shows the error was identified in March and the disclosure went in during June, the twenty-day window closed long before it was filed. The workable habit is to date-stamp the discovery in the same file as the disclosure: the working paper that surfaced it, who saw it, and when the calculation was finalised.
Note also what the twenty days does not buy you. It is a filing deadline, not a penalty holiday. The monthly penalty described below accrues from the day after the original return was due, whether you took two days to file or nineteen.
Form 211 is the VAT form, and there is no Form 211 for corporate tax
The label comes from the FTA’s own form numbering. The Authority’s Voluntary Disclosure User Guide for VAT and Excise Tax uses VAT211 for the VAT voluntary disclosure, against VAT201 for the VAT return, and EX214 for the excise equivalent. So “Form 211” is a real reference, and it is a VAT reference.
Two qualifications matter. That guide dates from February 2022 and predates EmaraTax; the numbering survives but the submission route is now the EmaraTax dashboard, where the disclosure is raised against the specific return or refund application it corrects rather than filed as a standalone document. And there is no corporate tax “Form 211” at all. A corporate tax disclosure is made against the filed CT return under a separate penalty table, which is covered further down.
If a checklist tells you to file Form 211 for a corporate tax error, it has been copied from VAT guidance. Confirm the tax type before the form number.
From 14 April 2026 the VAT penalty is 1% a month, not 5% to 40%
The operative instrument is Cabinet Decision No. 40 of 2017 and its amendments, whose Table No. 1 was rewritten by Cabinet Decision No. 129 of 2025, issued 9 October 2025 and effective 14 April 2026. Item 11 of that table now reads as a single rate: a monthly penalty of 1% on the Tax Difference, for each month or part thereof, from the day after the return was due, or after the refund application was submitted, until the day the Voluntary Disclosure is filed.
| Charge | Until 13 April 2026 | From 14 April 2026 |
|---|---|---|
| Voluntary Disclosure, filed before any audit notice | 5% within year one, then 10%, 20%, 30%, 40% by year of delay | 1% per month or part month |
| Failure to disclose before the audit notice | 50% fixed, plus 4% per month | 15% fixed, plus 1% per month |
| Incorrect Tax Return | AED 1,000, or AED 2,000 on repetition | AED 500, waived in two cases |
| Late payment of Payable Tax | 2% immediately, then 4% monthly, capped at 300% | 14% per annum, monthly, no stated cap |
Read across that table honestly and it is not a uniform relief. The 1% monthly rate reaches 5% in five months, so an error disclosed within five months of the due date is cheaper than it was, while one disclosed in month eleven costs 11% where the old scale charged 5% for the whole of year one. What has been cut sharply is the price of being caught: 50% plus 4% a month has become 15% plus 1%.
The incorrect-return line is worth reading closely too. Item 10 now sets AED 500 rather than AED 1,000, and lifts it entirely in two cases: where you correct the return within its own submission deadline, and where the Voluntary Disclosure corrects the return without producing a difference in Due Tax. That second carve-out is what makes a clause 5 no-difference disclosure a penalty-free act on the face of the table.
Waiting for the audit notice adds a fixed 15% to the same difference
Item 12 of the amended table deals with the taxpayer who does not disclose before the FTA notifies an audit. Two charges land together: a fixed 15% of the Tax Difference, and the 1% monthly charge on that same difference. The monthly element runs to the date the disclosure is finally submitted, or, if none is ever submitted, to the date the FTA issues its Tax Assessment.
Since the FTA gives at least ten business days of notice before an audit, there is a narrow and ill-advised window in which a company might try to file after the notice arrives. It does not help. The 15% attaches to the failure to disclose before notification, and the notification has already happened.
Late payment is now 14% a year, and the disclosure buys twenty business days
Item 9 of the amended table replaces the old 2%-then-4% structure with a monthly penalty at 14% per annum on the unsettled Payable Tax, from the day after the due date. The old 300% cap is not carried over into the new wording.
The provision that matters for a disclosure is the second half of item 9, which sets the due date for payment in these cases:
- Voluntary Disclosure: 20 business days from the date of submission.
- Tax Assessment: 20 business days from the date of receipt.
So the disclosure resets the payment clock. Settle the additional tax within twenty business days of filing and no late-payment penalty attaches to it. Miss that window and the 14% annual rate starts, on top of the 1% monthly disclosure penalty that has already accrued. Filing without funding the payment is the expensive way to do this.
Corporate tax has run on these rules since 2023
What changed in April 2026 is that VAT was brought into line with corporate tax, not the other way round. Cabinet Decision No. 75 of 2023, as amended by Cabinet Decision No. 10 of 2024, has carried the same structure for corporate tax from the start:
- Item 10: 1% per month on the Tax Difference for a Voluntary Disclosure.
- Item 11: 15% fixed plus 1% per month where no disclosure precedes the audit notice.
- Item 8: 14% per annum monthly on unsettled Payable Tax, with the same 20-business-day due date after a disclosure.
- Item 9: AED 500 for an incorrect Tax Return, unless corrected before the filing deadline.
For a free zone group filing both taxes, the practical effect is that one set of numbers now governs both. The AED 10,000 threshold and the twenty-day awareness window apply across the board, because they sit in the Tax Procedures Law and its Executive Regulation rather than in either tax’s own legislation.
What the arithmetic looks like on a real number
Take a Designated Zone trading company whose VAT return for the quarter ended 31 March 2026 was due on 28 April 2026. In November 2026 a review finds output VAT understated by AED 120,000 — a supply treated as outside scope that was not. The disclosure is filed on 20 November 2026, roughly seven part-months after the due date.
| Scenario | Calculation | Penalty |
|---|---|---|
| Disclosed voluntarily, before any audit notice | 1% × 7 part-months × AED 120,000 | AED 8,400 |
| Incorrect return charge alongside it | Item 10 fixed amount, neither carve-out available | AED 500 |
| Not disclosed; FTA notifies an audit first | 15% × AED 120,000, plus the AED 8,400 above | AED 26,400 |
| Tax settled more than 20 business days after filing | 14% per annum, monthly, on AED 120,000 | About AED 1,400 per month |
The AED 120,000 of tax is payable in every row. Waiting for the FTA to find it costs an extra AED 18,000, and the difference between filing on day one of awareness and day nineteen is nothing at all, provided both fall inside the same part-month.
Five years is the outer limit, and the fifth year is a trap
Article 46 of the Tax Procedures Law sets the boundaries in both directions:
- The FTA generally cannot audit or assess after five years from the end of the relevant Tax Period.
- You cannot submit a Voluntary Disclosure after those five years either. Clause 5 is explicit.
- A disclosure filed in the fifth year re-opens the door: the FTA may then audit or assess beyond the five years, provided it completes within one year of your submission.
- Where the FTA notified an audit before the five years expired, it has four years from that notification to finish.
- Tax evasion, and failure to register at all, extend the period to fifteen years.
The fifth-year point deserves a decision rather than a reflex. A late disclosure on an otherwise time-barred period hands the Authority a fresh twelve months to examine that period. Where the amount is material that is usually still the right call; where it is not, it is a judgement to take with your tax agent before filing rather than after.
Free zone companies carry a second exposure behind the penalty
The penalty is arithmetic. The status question is not. A Qualifying Free Zone Person pays 0% on Qualifying Income and 9% on everything else, and it holds that status only while every condition holds — including the de minimis rule that non-qualifying revenue must stay below the lower of AED 5,000,000 or 5% of total revenue. Failing a condition costs QFZP status for that Tax Period and the four that follow.
That is why a corporate tax correction in a free zone entity is rarely just a number. A reclassified stream can move revenue across the qualifying line, and the same restatement that generates a modest 1% monthly penalty can carry a five-period consequence behind it. Model the revenue split before you model the penalty, and read the disclosure alongside your registration and filing obligations rather than in isolation.
A short pre-filing checklist
- Fix the tax type first. VAT and excise sit under Cabinet Decision No. 40 of 2017 as amended; corporate tax sits under Cabinet Decision No. 75 of 2023.
- Measure the tax difference against AED 10,000 to decide between a disclosure and a next-return correction.
- Date-stamp when you became aware, and keep the working paper that proves it.
- Count part-months from the day after the original due date — the penalty is not pro-rated.
- Check whether an audit notice has been issued. It changes the charge by 15% of the difference.
- Have the payment ready to settle inside 20 business days of filing.
- Confirm the period is not beyond five years, and think twice inside year five.
- For a QFZP, re-run the de minimis test on the corrected figures before submitting.
Frequently Asked Questions
What is the penalty for a voluntary disclosure in the UAE in 2026?
For VAT and excise, 1% of the tax difference per month or part month from the day after the return was due until the disclosure is filed, under Table No. 1 item 11 of Cabinet Decision No. 40 of 2017 as amended by Cabinet Decision No. 129 of 2025, effective 14 April 2026. Corporate tax has carried the same 1% monthly rate since 2023 under Cabinet Decision No. 75 of 2023.
Is Form 211 used for corporate tax voluntary disclosures?
No. VAT211 is the FTA’s VAT voluntary disclosure form and EX214 is the excise equivalent. A corporate tax disclosure is raised against the filed corporate tax return in EmaraTax and has no 211 form number. Guidance that applies Form 211 to corporate tax has been copied from VAT material.
How long do I have to file a voluntary disclosure after finding an error?
Twenty business days from the date you became aware of the error, under Article 10 of Cabinet Decision No. 74 of 2023, where the understated tax exceeds AED 10,000. At AED 10,000 or less you correct it in the next return that is not yet due instead, and only file a disclosure if no such return exists.
Does filing a voluntary disclosure stop the late payment penalty?
It resets the payment due date. Item 9 of the amended table sets the due date for tax arising from a Voluntary Disclosure at 20 business days from submission, so paying inside that window avoids the late payment charge. Pay later and the 14% per annum monthly penalty runs on the unsettled amount, separately from the 1% monthly disclosure penalty.
What happens if the FTA finds the error before I disclose it?
Item 12 imposes a fixed 15% of the tax difference plus 1% per month on the same difference. The monthly element runs to the date a disclosure is eventually filed, or to the date the Tax Assessment is issued if none ever is. Before 14 April 2026 the same failure carried 50% plus 4% per month for VAT.
Can I still disclose an error from 2019?
No. Article 46(5) of the Tax Procedures Law bars a Voluntary Disclosure more than five years after the end of the relevant Tax Period. The exceptions run the other way: suspected tax evasion or a failure to register extend the FTA’s own audit window to fifteen years.
Do I have to disclose an error that does not change the tax due?
Yes. Article 10(5) requires a Taxpayer who finds an error or omission in a filed return to correct it by Voluntary Disclosure even where there is no difference in Due Tax. Item 10 of the amended penalty table expressly waives its AED 500 incorrect-return charge for a disclosure that produces no tax difference.
The FTA voluntary disclosure UAE 2026 regime rewards speed in months rather than years, and it punishes being found rather than being wrong. For a free zone company the discipline is unremarkable: reconcile often enough that errors surface in months, document the date you found them, hold the cash to settle within twenty business days, and treat a corporate tax correction as a status question before it is a penalty question. If you are weighing the numbers on your own free zone VAT position, work them through with a registered tax agent before anything is filed.
