The penalty rules changed — and fixing your own errors is now much cheaper

The UAE's updated tax penalty structure under Cabinet Decision No. 129 of 2025 took effect on 14 April 2026. The most important practical change: a voluntary disclosure filed under the new rules attracts around 1% per month on the unpaid tax — dramatically cheaper than the penalty the FTA applies when it finds the error. If you suspect a mistake in a past VAT or corporate tax return, correcting it yourself is now firmly the cheaper route.

Alongside cheaper self-correction, the FTA has broader audit powers and tighter deadlines. Two habits protect a Dubai business: keep clean records so errors surface quickly, and act on them through a voluntary disclosure rather than hoping an audit never comes.

The Penalties Every Dubai Business Should Know

• Late submission of a tax return:

  AED 1,000 for the first offence; AED 2,000 for a repeat within 24 months.

• Failure to settle payable tax on time:

  A monthly late-payment penalty accrues on the unpaid amount from the day after the due date.

• Late corporate tax registration:

  AED 10,000 — waived if the first return is filed within seven months of the end of the first tax period.

Penalty amounts change over time. Always confirm the current figures against the official FTA schedule before acting.

Voluntary Disclosure vs. Waiting for an Audit

How to File a Voluntary Disclosure

1. Quantify the error: identify the affected period and recalculate the correct tax figure.
2. Gather support: invoices, ledgers and workings that justify the corrected numbers.
3. Submit the VDF on EmaraTax: file the voluntary disclosure for the specific return and period.
4. Settle promptly: pay the corrected tax and penalty to stop further monthly charges accruing.

What changes on 14 April 2026

The UAE consolidated its tax-penalty rules: Cabinet Decision No. 129 of 2025, published in November 2025, replaces Cabinet Decision No. 108 of 2021 with effect from 14 April 2026 and harmonises administrative penalties across VAT, excise and tax procedures. The direction of travel is consistent — predictable fixed penalties, percentage-based exposure that grows the longer an error stays unreported, and better outcomes for businesses that come forward first. Any penalty planning done under the old tables is worth rechecking against the new regime.

A worked example: disclose now or wait

A Dubai retailer discovers it under-declared output VAT by AED 40,000 across two periods last year — a mapping error in its point-of-sale export. Filing a voluntary disclosure now means the fixed VD penalty plus a percentage loading on the shortfall that reflects early, unprompted correction. Waiting means the same error surfaces in an FTA audit — where the percentage bands are materially higher, the audit widens to neighbouring periods, and the “we knew but sat on it” timeline is visible in the accounting records. On any realistic set of numbers the disclosure is cheaper, and it converts an open-ended risk into a fixed, budgetable cost.

Common mistakes

How is a voluntary disclosure penalty calculated?

Two penalties apply when you correct an error through Form 211. The first is fixed: AED 1,000 for a first voluntary disclosure, AED 2,000 for a repeat within 24 months. The second is a percentage of the tax difference — and it grows with every year that passes between the due date of the original return and the day you disclose:

The message is blunt: the same AED 100,000 error costs AED 5,000 to fix in year one and AED 40,000 to fix in year five — plus the fixed fee and any late-payment penalty already accrued. Disclosure timing, not the error itself, usually decides the size of the bill.

One more timing point: a voluntary disclosure filed while an FTA audit of the same period is already underway loses much of its benefit — the percentages above assume you moved first. The moment an error surfaces in a reconciliation, price both routes the same week; waiting converts a cheap correction into an expensive assessment.

When can you fix an error in the next return instead?

Not every mistake needs Form 211. Where an error understates tax by AED 10,000 or less, the Tax Procedures rules let you correct it in the tax return for the current period — no separate disclosure, no percentage penalty. Anything above AED 10,000 must go through a formal voluntary disclosure. Two cautions: the AED 10,000 test applies per error, not per return, and the next-return route still requires working papers showing what was corrected and why — the FTA can and does ask during audits.

The legal basis

Voluntary disclosures are made under the Tax Procedures framework of Federal Decree-Law No. 28 of 2022 and its Executive Regulation, with the penalty schedule now unified by Cabinet Decision No. 129 of 2025 from 14 April 2026. If you have found an error, our voluntary disclosure service quantifies the exposure both ways before anything is filed, and our FTA audit support team handles cases where the notice has already arrived.
