Article about UAE Corporate Tax Voluntary Disclosure: – Reviewed by: Abraham, Senior Chartered Accountant at ProAct — Expert in Auditing, Accounting, Corporate Tax, VAT, AML, UAE Company Formation & Free Zone Compliance.
Most of our clients only learn about Voluntary Disclosure the day after they hit “submit” on their first Corporate Tax return — usually because their auditor spotted something the in-house team missed. That moment is uncomfortable. It is also, with the right move within the next 20 business days, recoverable.
As of 2025–2026, every taxable person in the UAE who has filed a Corporate Tax return through EmaraTax has the right — and in many cases the duty — to correct material errors using a UAE Corporate Tax Voluntary Disclosure. The mechanism existed before; what changed is the price tag.
If you have already filed a return for FY2024 or FY2025 and you are not 100% confident every figure was right, ask yourself this: would you rather flag the error yourself at a controlled cost, or wait for the Federal Tax Authority (FTA) to find it during a risk-based audit? That single decision can be the difference between a routine 1% monthly correction and a five-figure penalty bill.

What Is a UAE Corporate Tax Voluntary Disclosure?
A UAE Corporate Tax Voluntary Disclosure (VD) is a formal correction filed through the FTA’s EmaraTax portal when a taxable person identifies an error or omission in a previously submitted Corporate Tax return, tax assessment, or refund application. It must be filed within 20 business days of discovering the error. Filing a VD before the FTA opens an audit triggers a far smaller penalty than waiting for the Authority to find the mistake itself.
What Is a UAE Corporate Tax Voluntary Disclosure? (الإفصاح الطوعي / Добровольное раскрытие)
A Voluntary Disclosure is a self-initiated correction to a Corporate Tax return that has already been accepted by the FTA. It is not a re-filing of the original return.
Voluntary Disclosure (الإفصاح الطوعي / Добровольное раскрытие) is a formal notice — submitted on the form prepared by the FTA — through which a taxable person reports an error or omission in a previously filed Corporate Tax return, tax assessment, or refund application. In the UAE context, this means you are formally telling the Federal Tax Authority (FTA) about a mistake before the Authority discovers it through an audit. It applies to every taxable person registered for Corporate Tax under Federal Decree-Law No. 47 of 2022, including mainland companies, Qualifying Free Zone Persons in DMCC, JAFZA, Meydan, RAKEZ and IFZA, and resident natural persons whose business turnover exceeded AED 1 million.
The Voluntary Disclosure mechanism is governed primarily by Article 10 of the UAE Tax Procedures Law (Federal Decree-Law No. 28 of 2022). For UAE Corporate Tax specifically, the administrative penalties applicable to Voluntary Disclosure are governed mainly by Cabinet Decision No. 75 of 2023, as amended.
We have seen this exact situation across our client base: a finance manager closes the books, files the CT return, and then the external auditor — completing fieldwork three months later — flags a misclassified expense, an under-reported related-party transaction, or a wrongly applied Qualifying Income test. At that moment, the clock starts.
If you are running a Free Zone company in DMCC or IFZA, here’s what matters most to you: the Voluntary Disclosure rules apply to your 0% Qualifying Income calculations exactly as they apply to a 9% mainland filer. Free Zone status does not switch the obligation off.
“In nine out of ten Voluntary Disclosure files we review, the original error is not the one that ends up costing the client the most — it’s the second-order issue we flag during the four-layer review. That’s why we don’t file a VD without running the full process.”

When Must You File a Voluntary Disclosure for UAE Corporate Tax?
A Voluntary Disclosure must generally be filed where an error or omission in a previously submitted Corporate Tax return results in underpaid tax, overpaid tax refund, or other cases specified by the FTA. The disclosure should generally be submitted within 20 business days from the date the error is identified.
The trigger is “knowledge”. The day a director, finance manager, internal auditor, or external accountant becomes aware that a return contains a material error is the day the 20-business-day requirement arises under the UAE Tax Procedures framework and related Executive Regulations implementing Article 10 of the Tax Procedures Law. Postponing the disclosure because “we’ll fix it next year” is not a defence; it is an aggravating factor.
Three situations almost always require a Voluntary Disclosure. First, the tax payable on the return was understated — for example, an expense that turns out not to be deductible, or revenue from a non-qualifying activity wrongly placed in a Qualifying Free Zone Person’s 0% bucket. Second, the tax payable was overstated and you are owed a refund. Certain structural or disclosure-related errors — such as incorrect tax group details, connected-person disclosures, or tax period information — may also require correction through the mechanisms prescribed by the FTA, depending on whether the error impacts the tax position.
Not every typo is a Voluntary Disclosure. A clerical error in a name, address, or trade licence number — where there is no impact on tax due — can usually be fixed by amendment without triggering the VD penalty regime, although the FTA’s published guidance still requires you to notify the Authority.
The five-year window matters. Under the Tax Procedures Law, the FTA can generally reassess a return for up to five years after the end of the relevant tax period. Voluntary Disclosures can also be filed within that window — meaning a 2024 error can theoretically be disclosed up to the end of 2029, but every additional month adds another 1% monthly penalty stack.
A common mistake that is easy to avoid is treating Voluntary Disclosure as a year-end exercise. The 20-business-day rule cuts across financial calendars. The day your auditor’s draft management letter lands on your desk, the disclosure clock has already started.
Discovery — not the year-end close — starts the 20-business-day clock under Article 10 of the Tax Procedures Law.
How Are UAE Corporate Tax Voluntary Disclosure Penalties Calculated in 2026?
For UAE Corporate Tax, Voluntary Disclosure penalties are governed mainly by Cabinet Decision No. 75 of 2023, as amended. Under this framework, a Voluntary Disclosure involving a tax difference may attract an administrative penalty equal to 1% of the tax difference per month — or part of a month — calculated from the day following the due date of the relevant Corporate Tax return until the date the Voluntary Disclosure is submitted.
If the Voluntary Disclosure is submitted after the Federal Tax Authority issues a tax audit notification for the relevant period, an additional fixed penalty of 15% of the tax difference may apply.
Unpaid Corporate Tax may also attract a late-payment administrative penalty calculated at 14% per annum, charged monthly on the unpaid tax amount.
Under the previous regime — Cabinet Decision No. 49 of 2021 — Voluntary Disclosure penalties stacked in tiers: 5% if filed within one year of the original due date, rising through 10%, 20%, 30% and reaching 40% if filed in the fifth year. After an audit notice, a flat 50% penalty applied on top of a 4% monthly charge. The math discouraged late corrections.
From 14 April 2026, the Voluntary Disclosure penalty is 1% of the tax difference per month — or part of a month — calculated from the original return due date until the day the VD is filed. If a Voluntary Disclosure is filed after the FTA has issued an audit notice for that period, a fixed 15% penalty applies on top of the same 1% monthly charge. Full details are set out in the Federal Tax Authority’s Tax Procedures publications and the Ministry of Finance UAE tax penalty announcement.
Here is the question we get asked most: “Is it cheaper to disclose now or take the chance?” The honest answer for almost every case we review is that disclosing now is cheaper — because the alternative is the 15% fixed penalty plus the same monthly clock if the FTA finds the error during a risk-based audit, plus late-payment administrative penalty on the unpaid tax at 14% per annum.

Under the UAE Corporate Tax penalty framework, every additional month of silence costs another 1% of the tax difference.
What Errors Trigger a Voluntary Disclosure — and Which Don’t?
Errors that result in underpaid Corporate Tax, incorrect refunds, or materially incorrect disclosures may require a Voluntary Disclosure or other correction mechanism prescribed by the FTA. Errors with no tax impact may not require a VD but still need correction through EmaraTax.
Across the returns we review, five categories produce most of the post-filing corrections.
Misapplied Qualifying Free Zone Person (QFZP) tests sit at the top. A DMCC or IFZA company books non-qualifying income — typically excluded activities — into the 0% Qualifying Income column, then realises during audit that the de minimis threshold has been breached. The correction may require a Voluntary Disclosure reclassifying the income under the applicable Corporate Tax treatment.
Connected-person and related-party errors are the second most common. Director’s remuneration above market rate, intercompany management fees with no documentation, and shareholder loans without arm’s-length interest terms all create disallowable expenses under Article 36 of the Corporate Tax Law. Each of these pushes taxable income up — and therefore demands a Voluntary Disclosure once spotted. Our Connected Person Compensation UAE guide explains the market-rate test in more detail.
Small Business Relief (SBR) eligibility — Small Business Relief eligibility should be reviewed carefully before filing the Corporate Tax return, particularly where revenue approaches or exceeds AED 3 million, as an incorrect election may later require correction.
The fourth category covers transfer pricing documentation gaps. Where a related-party transaction is listed on the return without the supporting Local File or Master File ready, the FTA’s data analytics tools will flag it. A pre-emptive Voluntary Disclosure with the corrected disclosures is almost always preferable to defending it during an audit.
Finally, simple arithmetic and classification errors — depreciation schedules, foreign exchange differences, revenue recognition timing — round out the list. These are the easiest to fix and usually carry the smallest tax difference.
Top Five Corporate Tax Errors That Trigger a Voluntary Disclosure
- Misclassified Qualifying Free Zone Person income (DMCC, JAFZA, IFZA)
- Connected-person remuneration above market rate
- Wrongly elected Small Business Relief above AED 3 million revenue
- Missing or incomplete transfer pricing disclosures
- Arithmetic, depreciation, or revenue-recognition errors with material tax impact
Errors with no tax impact — a misspelt trade name, a wrongly typed tax registration number on the return cover sheet — usually do not require a Voluntary Disclosure under the FTA’s published guidance, but the Authority still expects notification through EmaraTax. When in doubt, treat it as a VD.
If the correction materially impacts the tax payable position, a Voluntary Disclosure or other correction mechanism prescribed by the FTA may be required.
How Do You File a Corporate Tax Voluntary Disclosure Through EmaraTax?
You file a Corporate Tax Voluntary Disclosure by logging into EmaraTax, opening the previously submitted return, selecting the Voluntary Disclosure action, entering the corrected figures alongside the original ones, attaching evidence, and submitting. The process is fully digital and typically takes less than two hours for a routine correction.
Here are the steps in order, exactly as our team executes them for clients.
Step 1 — Confirm the trigger and the deadline. Before opening EmaraTax, document in writing the date the error was discovered, who discovered it, and the magnitude of the tax difference. This single document protects you if the disclosure timing is ever challenged.
Step 2 — Log into EmaraTax and open the relevant tax period. Navigate to the Corporate Tax dashboard inside your taxpayer profile. Locate the filed return that contains the error and select “Voluntary Disclosure / Amendment” from the Action menu.
Step 3 — Complete the Voluntary Disclosure form. The form requires both the original incorrect figures and the corrected figures, line by line. EmaraTax automatically calculates the tax difference and the applicable monthly penalty under prevailing UAE Corporate Tax penalty framework.
Step 4 — Attach supporting evidence. The form has a dedicated upload section. Standard attachments include: the corrected trial balance, the audited or management financial statements supporting the correction, a written explanation of the error, transfer pricing documentation if relevant, and any related-party invoices or contracts.
Step 5 — Review, declare, and submit. The authorised signatory — usually a director or the registered tax agent — confirms the declaration and submits. EmaraTax issues a VD reference number immediately.
Step 6 — Pay the additional tax and penalty. The FTA generates a payment due notice. The 14% per annum late-payment administrative penalty begins to accrue from the day after the original payment due date until the additional tax is settled.
Step 7 — Retain records for five years. Under Article 78 of the Tax Procedures Law, all supporting evidence must be kept for at least five years from the end of the relevant tax period.
If you are nearing the 20-business-day deadline and the evidence pack is not ready, request a same-week Voluntary Disclosure preparation session with ProAct’s tax compliance team.
The EmaraTax Voluntary Disclosure flow is digital end-to-end, but the audit trail you build outside the platform is what protects you in any future FTA review.
What Documents and Evidence Will the FTA Expect with Your VD?
The FTA expects a complete, contemporaneous evidence pack with every Voluntary Disclosure — not just the corrected numbers. A weak evidence file is the single biggest reason VDs are reopened during later audits.
Something we see every year is taxpayers uploading only the corrected figures, omitting the explanation of why the original figure was wrong. The Authority’s reviewers do not just compare the two numbers; they assess whether the correction is reasonable, supportable, and consistent with the underlying records.
A complete VD evidence pack contains the corrected trial balance for the full tax period, the audited financial statements where available, the written narrative explaining the discovery and the nature of the error, the legal basis for the correction (Article reference and any applicable FTA Public Clarification), updated transfer pricing documentation if related parties are involved, and a reconciliation showing how the corrected figures tie back to the underlying accounting records. The list mirrors the documentation the Federal Tax Authority requires under its general record-keeping standards, summarised in our UAE Corporate Tax Return Guide 2026.
For Qualifying Free Zone Person reclassifications, the FTA also expects the de minimis calculation, the activity-by-activity Qualifying Income test, and contracts demonstrating the revised treatment. We have seen QFZP reclassifications rejected purely because the de minimis math was not shown on the face of the supporting workpaper.
The evidence pack is the Voluntary Disclosure. The form is just the cover sheet.
ProAct’s 4-Layer Voluntary Disclosure Review Workflow
Before any Voluntary Disclosure is filed for a client, ProAct runs the same four-stage internal review every time. The workflow is built to catch second-order errors and ensure the disclosure withstands a future FTA audit.
Step 1 — Data Gathering. We collect the original return, the trial balance for the period, all supporting workpapers, the management letter or audit findings that surfaced the error, and any related-party documentation. Nothing moves to Layer 2 until the data set is complete.
Step 2 — 4-Layer Review. A senior chartered accountant performs an independent technical review against the Corporate Tax Law and current FTA guidance. A second reviewer challenges the legal basis. A third reviewer verifies the numerical accuracy and the monthly-penalty calculation. A fourth — our Senior Chartered Accountant — performs the final sign-off review.
Step 3 — Issue Flagging. Any second-order issues identified during review — for example, an SBR election that becomes unsustainable once the correction is made — are flagged in writing and discussed with the client before filing. We do not file a VD that creates a new exposure.
Step 4 — Documentation and Filing. The full evidence pack is assembled, the EmaraTax submission is prepared, the authorised signatory approves, and the VD is filed with the FTA reference number recorded against the client’s permanent file.
Request a compliance review from ProAct before your next Voluntary Disclosure deadline.
Why Work with ProAct Chartered Accountants for Your Voluntary Disclosure?
A Voluntary Disclosure is not a clerical exercise. It is a regulated submission that becomes part of your permanent FTA record and can be referred back to during any audit for the next five years.
Here is something that surprises most clients: the cost difference between a well-prepared VD and a rushed one is rarely the FTA penalty itself. It is the second-order risk — the SBR election that quietly fails once income is reclassified, the QFZP status that lapses, the transfer pricing position that no longer holds.
ProAct Chartered Accountants advises on UAE Corporate Tax Voluntary Disclosures across mainland and free zone clients in Dubai, Abu Dhabi, and the wider UAE — including DMCC, JAFZA, Meydan, RAKEZ and IFZA — combining technical review, EmaraTax filing, and post-filing audit defence in a single engagement.
Across the disclosures we file, the majority of cases we review identify at least one related issue beyond the original error — which is why the 4-Layer Review exists.
When you contact ProAct, you will receive a response within 24 hours from a qualified chartered accountant — not a sales representative. The first conversation is a scoping call. We tell you, in plain English, whether a Voluntary Disclosure is required, what the penalty exposure looks like under the applicable UAE Corporate Tax penalty framework, and what documentation we will need. There is no obligation to engage further, and there is no sales pitch.

Frequently Asked Questions
1. How many days do I have to file a Voluntary Disclosure for UAE Corporate Tax?
Under the UAE Tax Procedures framework implementing Article 10 of Federal Decree-Law No. 28 of 2022, a Voluntary Disclosure should generally be submitted within 20 business days from identifying the error. The clock starts on the date of knowledge — typically when an auditor or finance manager confirms the error in writing. Filing later than 20 business days does not invalidate the disclosure but exposes the taxable person to additional penalty risk under the applicable UAE Corporate Tax rules.
2. What is the penalty for a Voluntary Disclosure under Cabinet Decision No. 75 of 2023, as amended?
The Voluntary Disclosure penalty is 1% of the tax difference per month — or part of a month — calculated from the original return due date until the VD is filed. If the VD is filed after the FTA has issued an audit notification, a fixed 15% penalty also applies. Late-payment administrative penalty of 14% per annum runs separately on the unpaid tax under the same Cabinet Decision.
3. Can I file a Voluntary Disclosure if my Corporate Tax return is being audited by FTA?
Yes, but the cost is significantly higher. A VD filed after the FTA issues a notice of audit attracts a fixed 15% penalty on top of the 1% monthly charge under the UAE Corporate Tax administrative penalty framework. Filing before the audit notice — even one day before — preserves the lower 1%-monthly-only treatment, which is why early identification matters more than perfect documentation.
4. Do Qualifying Free Zone Persons in DMCC or IFZA have to file Voluntary Disclosures?
Yes. Every taxable person in the UAE — including Qualifying Free Zone Persons in DMCC, JAFZA, IFZA, Meydan, RAKEZ and other free zones — is subject to the Voluntary Disclosure obligation under the Tax Procedures Law. QFZP reclassifications are among the most common VD triggers, particularly where non-qualifying income has been wrongly reported in the 0% column or the de minimis threshold has been breached.
5. What happens if I don’t file a Voluntary Disclosure and the FTA finds the error?
If the FTA discovers the error through an audit, a fixed 15% administrative penalty applies on the unpaid tax under the UAE Corporate Tax administrative penalty framework, in addition to 14% per annum late-payment administrative penalty and any 1% monthly Voluntary Disclosure penalty if a VD is then filed during the audit. The combined cost is typically two to four times higher than disclosing voluntarily before any audit notice.
6. Can a Voluntary Disclosure be amended or withdrawn?
A submitted Voluntary Disclosure cannot be withdrawn, but if a further error is discovered after the VD is filed, a second Voluntary Disclosure can be filed against the same period. There is no statutory limit on the number of VDs per tax period. Each subsequent VD restarts its own 1% monthly penalty calculation from the original return due date until the new disclosure is filed.
7. Does a Voluntary Disclosure increase my chances of an FTA audit?
Not directly. The FTA’s stated position — confirmed in the Federal Tax Authority’s published audit guidance — is that risk-based audits are driven by data analytics, sector risk, and discrepancies, not by the act of filing a VD. A well-documented Voluntary Disclosure often reduces audit risk on that period because the corrected position is now on file with full evidence.
