Voluntary Disclosure UAE Corporate Tax (2026): Correcting a Filed Return
A voluntary disclosure is the formal mechanism for correcting an error in a corporate tax return, tax assessment, or refund application already submitted to the Federal Tax Authority. It is filed through EmaraTax, and any resulting tax difference is payable within 20 business days of submission. The governing principle since the penalty framework was revised by Cabinet Decision No. 129 of 2025, effective 14 April 2026, is straightforward: correcting an error before the FTA notifies you of an audit costs materially less than being found out.
The single most important timing rule
The framework is built to reward self-correction. Disclose before an audit notice and you face the lower penalty tier. Disclose after being notified of an audit — or have the error found during one — and an additional fixed penalty of 15% of the tax difference applies, alongside a monthly charge of 1% on that difference.
The practical consequence: if you suspect an error, the value of acting is highest today and falls every day you wait. An audit notice closes the favourable window permanently.
When a voluntary disclosure is required
Where an error in a filed return, assessment, or refund application results in a difference in the tax payable. Common corporate tax examples:
Accounting income misstated, or adjustments applied incorrectly.
Small Business Relief claimed without meeting every condition, or missed when it was available Small Business Relief →.
Qualifying Free Zone Person status claimed or surrendered on the wrong basis — particularly relevant given Ministerial Decision No. 229 of 2025 applies retroactively from 1 June 2023 MD 229 & MD 230 explained →.
Related party transactions omitted or mispriced transfer pricing requirements →.
Losses brought forward incorrectly, or the 75% offset cap misapplied.
Exempt income treated incorrectly.
Where an error produces no difference in tax payable, the current framework allows correction through the next return rather than a formal voluntary disclosure — a simplification introduced with the 2026 changes.
How to file one
1. Establish the correct figures first. Reconstruct the position properly; a voluntary disclosure containing a second error is worse than the original.
2. Log in to EmaraTax and open the relevant tax period for the taxable person how to file on EmaraTax →.
3. Submit the voluntary disclosure, setting out the correction and the resulting tax difference, with supporting documentation.
4. Pay the tax difference within 20 business days of submission. Late payment beyond that window attracts the late payment penalty of 14% per annum, applied monthly.
Free zone companies: a specific reason to review
Ministerial Decision No. 229 of 2025 replaced the earlier Qualifying Activities rules and applies retroactively from 1 June 2023. Free zone companies that filed FY2023 or FY2024 returns treating income as non-qualifying under the narrower definitions may find that income now qualifies. Where that reduces tax paid, a voluntary disclosure is the route to correct it.
This cuts both ways — a position that looked safe under the old rules should also be re-tested. Either way the review is better done now than after an audit notice.
Voluntary disclosure is not the same as a reconsideration request
These are frequently confused and the distinction matters. A voluntary disclosure corrects your own filing error — file it as soon as identified, with payment due within 20 business days of submission. A reconsideration request challenges an FTA decision or penalty — it must be submitted within 40 business days of notification, in Arabic fines advisory →.
Filing the wrong one wastes the window for the other.
What it costs to do nothing
An uncorrected error does not become safe with age. The FTA can request records at any point within the seven-year retention period, and errors found during an audit carry the higher penalty tier. Meanwhile the underlying tax difference accrues late payment charges from the original due date what to do if you missed a filing deadline →.
