The 0% Rate Is Real. It Is Just Not Automatic.
If you have read that a Dubai free zone company pays no corporate tax, the good news is that you were not lied to. The UAE does offer a 0% corporate tax rate to free zone businesses, and it is written into the law. The bad news is what the setup adverts leave out: the 0% rate is a status the company has to earn and keep, year after year. It does not come stapled to the trade licence.
Here is the starting point, in plain terms. Since 1 June 2023, the UAE has had a federal corporate tax. The standard rate is 9% on taxable profit above AED 375,000, and 0% on the first AED 375,000. This applies across the country, including inside the free zones. A free zone company is a taxable company like any other. It has to register, file a return, and keep records.
What the free zones add is a separate, better rate for a specific kind of business: the Qualifying Free Zone Person, or QFZP. A QFZP pays 0% on its Qualifying Income and 9% on the rest. Everything then turns on two facts: whether the company is a QFZP at all, and how much of its income actually qualifies for the 0%. Both are answered by what the company does, not by the zone it registered in.
The framework that decides this sits in three documents. Federal Decree-Law No. 47 of 2022 is the corporate tax law itself, and Article 18 sets the QFZP conditions. Cabinet Decision No. 100 of 2023 defines what counts as Qualifying Income. Ministerial Decision No. 229 of 2025, which replaced an earlier 2023 decision and applies back to 1 June 2023, sets out the detailed lists of activities that qualify and the activities that do not. A free zone company relying on advice written before late 2025 may be relying on rules that have since been replaced.
What the Setup Pages Leave Out
The gap between the marketing and the law is wide enough to be worth naming directly. Here is the difference, point by point.
- "Free zone companies pay 0% tax." In fact, free zone companies are taxable. Only a Qualifying Free Zone Person pays 0%, and only on Qualifying Income.
- "The licence gives you the 0% rate." In fact, the 0% rate comes from meeting five conditions every year, not from the licence.
- "You only pay tax on the part that does not qualify." In fact, cross the de minimis line and 9% applies to all of your income, not just the excess.
- "If it goes wrong, you fix it next year." In fact, failing the test locks you out of the 0% rate for five tax periods.
- "Nobody is really checking yet." In fact, the FTA made about 93,000 field inspection visits in 2024 and can now audit back 15 years in serious cases.
None of this means the 0% rate is a trap or a trick. It means the rate is conditional, and the conditions are specific. A company that is built to meet them keeps the 0%. A company that treats the licence as the finish line is the one that gets a 9% assessment two years later. The rest of this article walks through what the conditions actually are, where companies lose the rate, and what changes once a UK owner is involved.
The Five Things That Have to Stay True
To be a QFZP in a given tax period, a company has to meet five conditions at the same time. Article 18 of Federal Decree-Law No. 47 of 2022 lists them, and they are cumulative, which means failing any one of them is enough to lose the status. The detailed walk-through of each condition is in the deep guide to how a free zone company earns and loses the 0% rate; the plain version is below.
It has to be a recognised Free Zone Person. The company must be set up in a free zone that is actually recognised for corporate tax. Most well-known zones are, but the status comes from the zone being recognised, not from the word "free zone" on the licence.
It has to have real substance in the UAE. The company must run its core activities from the free zone, with enough staff, premises, assets, and spending to match what it does. A company that is a name on a flexi-desk while the real work happens somewhere else does not have substance. Some activities can be outsourced to another free zone business, but only under supervision and only where that business has substance of its own.
It has to earn Qualifying Income. This is the heart of it, and it is covered in its own section below. Income that is not on the qualifying list is non-qualifying, and too much of it breaks the status.
It must not have elected the standard regime. A free zone company is allowed to choose to be taxed at the normal 9% rate instead. If it makes that election, it is no longer a QFZP. The choice is deliberate, but it is also sticky, so it should not be made by accident.
It has to price related-party deals at arm's length. Any transaction with a connected company or person has to be priced as if the two sides were strangers, and the company has to keep transfer-pricing documentation to prove it. A management fee or an intercompany sale set at a number that suits the group, rather than the market, breaks this condition on its own.
The point that gets lost is that these are not boxes ticked once at setup. They have to be true in every tax period. A company that qualified comfortably in its first year can fall out of the status in its third because it hired less, moved its decision-making, or started selling to a different kind of customer.
Qualifying Income, in Plain Terms
Qualifying Income is a closed list under Cabinet Decision No. 100 of 2023. Closed means that if a type of income is not on the list, it does not qualify. There is no general "free zone income is fine" category. In practice the qualifying buckets are:
- Income from dealing with other free zone businesses, where that other business is the genuine end user of the goods or service, not a middleman passing it on.
- Income from a defined list of Qualifying Activities done with customers outside the free zones, such as manufacturing, processing, trading certain commodities, holding shares for investment, headquarter services to group companies, and treasury and financing for group companies.
- Income from qualifying intellectual property, calculated by an OECD formula that rewards research the company actually did itself.
Sitting against this is a list of Excluded Activities, and income from any of them is non-qualifying no matter who the customer is. The ones that catch ordinary businesses most often are income from transactions with individuals (rather than companies), banking and insurance, finance and leasing to unrelated parties, and most income from owning or using real estate. So a free zone consultancy that invoices private individuals, or a free zone company that earns rent from a residential flat, is earning non-qualifying income whether it realises it or not.
This is why a QFZP's revenue cannot be looked at as one annual number. It has to be sorted transaction by transaction into qualifying and non-qualifying before anything else can be worked out. A single mixed figure on a management account tells you nothing about whether the 0% rate survives.
The 5% Rule That Ends the 0%
A business is never going to have perfectly clean revenue, and the law accepts that. It allows a small amount of non-qualifying income before the status breaks. This is the de minimis rule, and it is the single most important number in the regime.
The ceiling is the lower of two figures: 5% of total revenue, or AED 5 million. The word "lower" is what surprises people. For a small company, 5% is the binding limit. For a large one, the AED 5 million cap bites long before 5% would. A company with AED 200 million of revenue does not get AED 10 million of headroom; it gets AED 5 million, because AED 5 million is the lower of the two.
A worked example makes it concrete. Take a free zone company with AED 60 million of total revenue in the year. 5% of that is AED 3 million, and AED 3 million is lower than AED 5 million, so the ceiling is AED 3 million. If its non-qualifying income is AED 2 million, it stays a QFZP: it pays 0% on its qualifying income and 9% on the AED 2 million. If its non-qualifying income is AED 4 million, it has breached the ceiling, and the consequence is not that it pays 9% on the AED 4 million. It pays 9% on everything, including all the income that would otherwise have been at 0%.
That is the part the marketing never mentions. The de minimis rule is not a small-print rounding allowance. It is a cliff. One AED 4 million invoice to the wrong type of customer, in a company that assumed it was safely at 0%, can convert the entire year to 9%.
The Five-Year Lockout
The cost of failing does not stop at the end of the bad year. Under Article 18 of Federal Decree-Law No. 47 of 2022, a company that loses QFZP status loses it for the current tax period and the following four. That is five tax periods in total at the standard 9% rate.
This changes how the failure should be understood. A breach is not a single-year tax bill that the company shrugs off and gets right next time. It removes the 0% rate for half a decade. For a profitable business, the difference between 0% and 9% across five years is usually a far larger number than anything saved on a cheap company-setup package. The lockout is also automatic; it is not a penalty the company can negotiate away after the event.
The practical takeaway is that the de minimis line and the five conditions should be monitored during the year, while there is still time to act, not discovered after the return is filed. By the time a problem appears in the accounts, the period it relates to is usually closed.
The FTA Is Checking Now
For the first couple of years of the corporate tax, it was possible to believe that nobody was really looking. That is no longer a safe assumption. The Federal Tax Authority reported around 93,000 field inspection visits in 2024, an increase of about 135% on the year before, and it has moved to risk-based selection driven by data rather than random sampling. Many of those visits were excise and VAT inspections rather than corporate tax audits, but the same data and analytics now feed corporate tax reviews after returns are filed. The direction of travel is clear, and it is towards more scrutiny, not less.
Three hard dates and numbers are worth keeping in view, and the full picture is in the deep guide to the UAE FTA tax audit and the 2026 procedures.
Registration. A taxable company has to register for corporate tax, and missing the deadline carries a fixed AED 10,000 penalty. Registration is not optional for a free zone company, even one expecting to pay 0%.
Filing. The corporate tax return is due within nine months of the end of the tax period. For a company with a calendar year end of 31 December 2025, that means a return due by 30 September 2026. The same deadline is the payment deadline.
The audit window. From 1 January 2026, Federal Decree-Law No. 17 of 2025 extended how far back the FTA can audit. The general limit is five years, but it stretches to fifteen years in cases of tax evasion or failure to register. A company that took an aggressive 0% position cannot assume the exposure quietly closes after a few years.
The thread running through all of this is documentation. A QFZP claim is proven by records: the substance file, the transfer-pricing documentation, the analysis showing income sorted into qualifying and non-qualifying, and the working that shows the de minimis test was met. A company with the right structure but no contemporaneous records is in a weaker position, on an audit, than a company with a modest structure and a complete file. The audit reads the file. It does not read the brochure.
If You Also Have a UK Connection
For owners who are still connected to the UK, the UAE 0% rate is only half the picture. A 0% UAE company does not, by itself, keep its profits away from HM Revenue and Customs.
Two UK rules matter here. The first is corporate residence: if a UAE company is really run and controlled from the UK, HMRC can treat it as UK tax resident and tax it in the UK regardless of where it is registered. The second is the Controlled Foreign Company rules in Part 9A of the Taxation (International and Other Provisions) Act 2010, which can attribute the profits of a low-taxed foreign company back to a UK owner and tax them at the UK rate of 25%. A free zone company sitting at 0% is, by definition, low-taxed, which is exactly the kind of company those rules are built to catch. The companion guide on opening a Dubai company from the UK sets out where these rules bite.
This is the corridor point that setup providers do not reach, because it requires reading UK and UAE law together. The detail is in the guide to HMRC's CFC rules and the post-non-dom move to the UAE, and whether the owner personally stops being UK tax resident is a separate question decided by the Statutory Residence Test, covered in the guide to moving to Dubai from the UK. The short version is that a UAE 0% rate is necessary but not sufficient for a UK-connected owner. The UAE side has to deliver the 0%, and the UK side has to be structured so that the 0% is not simply undone by a UK charge on the same profit. For larger groups, the global minimum tax adds a further layer, explained in the guide to the UAE Domestic Minimum Top-up Tax and the 15% floor.
Who This Actually Applies To, and What to Check
The 0% free zone rate suits a genuine operating business that does most of its work from the UAE and sells to companies, not individuals. It suits a manufacturer, a trader, a group services or treasury company, a holding company. It fits much less well around a business that mainly invoices private clients, that earns rent, or that is really run from another country with a UAE company bolted on for the rate.
A short, honest self-check covers most of the risk:
- Confirm the company is in a free zone that is recognised for corporate tax.
- Check that the real work, with real people and real cost, is happening in the UAE.
- Identify whether the customers are companies or individuals.
- Measure the non-qualifying income against the lower of 5% of revenue or AED 5 million.
- Price related-party transactions at arm's length, and keep the documentation.
- Establish whether a UK or other foreign owner's home country could tax the same profit.
If those points are comfortable, the 0% rate is well within reach and worth keeping. If any of them is uncertain, that uncertainty is the thing to resolve before the next return, not after.
Frequently Asked Questions
Do free zone companies pay 0% corporate tax in the UAE?
A free zone company can pay 0%, but only if it is a Qualifying Free Zone Person and only on its Qualifying Income. Every free zone company is within the corporate tax system under Federal Decree-Law No. 47 of 2022 and has to register and file. Income that is not Qualifying Income, and any income at all once the company fails the QFZP test, is taxed at 9% above AED 375,000.
What is a Qualifying Free Zone Person?
A Qualifying Free Zone Person (QFZP) is a free zone company that meets five conditions in a tax period: it is a recognised Free Zone Person, it has adequate substance in the UAE, it earns Qualifying Income, it has not elected to be taxed under the standard 9% regime, and it prices related-party transactions at arm's length with documentation. A QFZP pays 0% on Qualifying Income and 9% on the rest.
What is the de minimis rule for UAE free zones?
The de minimis rule lets a QFZP earn a limited amount of non-qualifying income without losing its status. The limit is the lower of 5% of total revenue or AED 5 million. If non-qualifying income stays under that ceiling, the company keeps the 0% on its qualifying income. If it goes over, the company is taxed at 9% on all of its income for the period.
What happens if a free zone company loses its 0% status?
It is taxed at 9% on all of its taxable income for that period, not only on the part that caused the failure. It is also disqualified from the 0% rate for the current tax period and the next four, which is five tax periods in total under Article 18 of Federal Decree-Law No. 47 of 2022.
Does the free zone licence guarantee the 0% tax rate?
No. The licence registers the company in the zone; it does not confer the 0% rate. The 0% rate comes from meeting the QFZP conditions in each tax period. A company can hold a valid free zone licence and still be taxed at 9% because it fails one of the conditions or breaches the de minimis ceiling.
Does a free zone company still have to register and file for corporate tax?
Yes. Registration and filing are required even for a company expecting to pay 0%. Missing the registration deadline carries a fixed AED 10,000 penalty, and the corporate tax return is due within nine months of the end of the tax period.
Can a UK resident set up a UAE free zone company and avoid UK tax?
Not by registration alone. If the company is run and controlled from the UK, HMRC can treat it as UK tax resident. Even if it is not, the UK Controlled Foreign Company rules can attribute the profits of a low-taxed UAE company to a UK owner and tax them at 25%. A 0% UAE rate does not, on its own, remove a UK tax charge.
How far back can the FTA audit a free zone company?
The general audit window is five years from the end of the tax period. From 1 January 2026, under Federal Decree-Law No. 17 of 2025, it extends to fifteen years in cases of tax evasion or failure to register. Records that support a 0% position need to be kept and defensible for the full applicable period.
The 0% free zone rate is genuine, and it is worth having. It is also a status that is earned in the records and lost in the details, and the company that treats the licence as the end of the work is the one that finds out, on audit, that the rate was never secure.
