Voluntary Disclosure Penalty Relief for Corporate Tax in the UAE

The penalty table prices every tax-difference error twice. Item 10 is the price of confession: 1 percent of the tax difference for each month or part month, measured from the day after the original return's due date to the date the voluntary disclosure is submitted. Item 11 is the price of being found: a fixed 15 percent of the tax difference plus the same 1 percent per month, applied where the taxpayer failed to disclose before being notified of a tax audit.

The monthly component is identical in both items; it accrues with time regardless of behaviour. The fixed 15 percent is the pure surcharge on silence. That design makes the economics unambiguous: for any given error of any given age, disclosing is always cheaper than being found, and the gap never closes with time.

Both items measure months as months or part months, so an error disclosed 30 months and one day after the due date accrues 31 months of the 1 percent. The monthly clock, like the filing penalty clock, does not pro-rate.

Take a AED 50,000 underpayment. Discovered and disclosed 12 months after the return's due date, the penalty is 12 percent: AED 6,000. Found by the Authority instead, it is 15 percent fixed plus 12 percent monthly: AED 13,500. The disclosure saves AED 7,500.

Age the error to 30 months. Disclosed: 30 percent, AED 15,000. Found: 15 percent plus 30 percent, AED 22,500. The saving is still exactly the fixed 15 percent, AED 7,500, because the monthly component accrues identically in both scenarios. The lesson is that delay costs the same monthly charge whether you disclose or not; what disclosure buys is the removal of the fixed surcharge.

Now vary the size. On a AED 500,000 underpayment at 30 months, disclosed costs AED 150,000 and found costs AED 225,000: a AED 75,000 saving for the same paperwork. The larger the error, the more the disclosure is worth, which is the opposite of the intuition that big errors are scarier to disclose.

Three behaviours maximise what disclosure saves. First, disclose early in the error's life, because the monthly 1 percent is the one component you cannot avoid and it grows every month. An error disclosed in month 2 costs 2 percent; the same error disclosed in month 20 costs 20 percent. The fixed 15 percent saving is constant, but the total bill is not.

Second, disclose before any audit notification, because the notification is the event that locks in the 15 percent. Where an audit of any kind is rumoured or expected, the expected-value calculation favours immediate disclosure of known errors. Third, pay within the 20-business-day payment window after submission, because the disclosed tax otherwise starts accruing the 14 percent per annum item 8 charge on top of the disclosure penalties.

None of this requires the error to be fully quantified to the dirham before disclosing. Disclose the best-computed figures promptly and refine them through the review process; the submission date, which stops nothing but starts the payment window and evidences promptness, matters more than perfect precision on day one.
