Common Tax Consultancy Mistakes to Avoid in Dubai
The failure is rarely technical. It is an adviser still describing the UAE as it was before corporate tax.
Written from the files we are asked to clean up, this article sets out where tax advice in Dubai keeps going wrong: still selling the emirate as tax-free, reading a free zone licence as an exemption, treating DIFC and ADGM as separate tax jurisdictions, handling VAT as a rate rather than a records obligation, deferring transfer pricing to an overseas parent, and leaving the scope of the engagement itself undefined.

Most tax advice that goes wrong in Dubai does not fail on a hard technical point. It fails because the adviser is still working from the picture of the UAE that existed before there was a corporate tax at all. Corporate tax under Federal Decree-Law No. 47 of 2022 applies to financial years starting on or after 1 June 2023. VAT under Federal Decree-Law No. 8 of 2017, as amended by Federal Decree-Law No. 18 of 2022 and Federal Decree-Law No. 16 of 2024, has been running considerably longer. Both are administered by the Federal Tax Authority. The mistakes below are the ones that keep reappearing in the files we are asked to clean up.
Still selling the emirate as tax-free
The most damaging line in a client presentation is that Dubai has no tax. Under the corporate tax law the rate is 0% on taxable income up to a threshold set by Cabinet decision and 9% above that threshold. A business with real profits pays tax. An adviser who repeats the tax-free claim in a pitch, an investor deck or a group memo is not simply being loose with language; they are creating a shareholder expectation that the finance team will later have to walk back, usually in front of an auditor.

Treating the free zone licence as the answer to the tax question
A free zone licence is a licensing and regulatory status. It is not a tax exemption certificate. Free zone companies sit within the same federal corporate tax law as mainland companies, and any relief available to a free zone person depends on conditions set out in that legislation and in the decisions issued under it. Whether a particular company meets those conditions is a question about its activities, its income streams and its substance, not about the name on its trade licence.
The same confusion appears with DIFC and ADGM. ADGM is a common-law jurisdiction with its own courts and its own financial regulator, the FSRA. That independence is real for company law, employment and financial services regulation. It does not create a separate corporate tax system. An entity registered in DIFC or ADGM sits inside the federal regime, and its tax registration and filings run to the Federal Tax Authority like everyone else's.

Handling VAT as a rate rather than a records obligation
VAT is charged at 5%, which is the easy part and the part everyone remembers. The demanding part is everything around it: registering once the business crosses the threshold the law sets, treating exports and supplies between related entities correctly, issuing tax invoices that contain what the legislation actually requires, and keeping records in a form that survives being asked for. Most VAT penalties we see did not arise because someone applied the wrong rate. They arose because the paperwork behind a correct rate could not be produced.
Leaving transfer pricing to the head office
Where a Dubai entity buys from, sells to, lends to or is charged management fees by a related company, the pricing of those dealings is a UAE tax question and not merely a group accounting convention. Advisers frequently defer to whatever policy the overseas parent already runs, without testing it against what the UAE authority would expect to be shown. The result is a documented policy that describes a group in general terms and says almost nothing about the Dubai company's own functions, assets and risks. That gap is what a review finds first.
Not writing down who is responsible for what
Finally, the engagement itself. A large share of disputes between businesses and their tax advisers turn on scope: whether the adviser was retained to monitor legislative change, to prepare returns, to review the client's own figures, or only to answer the specific question that was asked. Where that is not written down, both sides argue afterwards about what should have been obvious. Defining the mandate at the outset costs less than litigating it later.
