Who Needs to Register for Corporate Tax in the UAE?

Almost every business in the UAE must register for corporate tax. This includes mainland companies, free zone companies, and individuals carrying on a business with total turnover above AED 1 million a year. Registration is mandatory even if your taxable income is below the AED 375,000 threshold, or your free zone income is taxed at 0%.

The short answer: who must register

You must register for UAE corporate tax if you are:

• A company incorporated in the UAE, mainland or free zone
• A free zone company, including one that qualifies for the 0% rate
• An individual carrying on a business in the UAE with total turnover above AED 1 million in a calendar year
• A foreign company that is effectively managed and controlled in the UAE, or that has a permanent establishment or taxable presence here

Registration is a separate obligation from paying tax. Many businesses that owe no tax at all still have to register and file.

UAE companies, mainland and free zone

Every juridical person resident in the UAE is within the corporate tax regime and must register. There is no minimum size or income level that exempts a company from registering. A company with modest profits, or even a loss, still registers and files an annual return.

Free zone companies

A common misunderstanding is that a free zone licence means no corporate tax and no paperwork. It does not. Free zone companies must register and file like any other company. A Qualifying Free Zone Person can access a 0% rate on its qualifying income if it meets all the conditions, but that is a benefit applied inside the regime, not a reason to skip registration.

Individuals and sole proprietors

Individuals are only brought into the regime when they carry on a business. The test is turnover: if your total turnover from business or commercial activities in the UAE exceeds AED 1 million in a Gregorian calendar year, you must register.

Crucially, some income does not count and does not create a registration requirement on its own:

• Salary and other employment income
• Personal investment income
• Income from personal real estate investment

So an employed person with a salary, or someone earning personal investment returns, is not pushed into corporate tax registration by that income alone.

Foreign and non-resident businesses

A foreign company can still fall within UAE corporate tax if it is effectively managed and controlled in the UAE, or if it has a permanent establishment or a taxable nexus in the country. In those cases a registration obligation arises on the UAE-connected activity.

When to register

For businesses incorporated now, the rule is to register within three months of incorporation. The earlier staggered deadlines that applied to businesses already operating when the regime began have passed. Missing your registration deadline triggers an AED 10,000 penalty, so the safe approach for any new entity is to register promptly through the FTA's EmaraTax portal rather than wait.

If you are unsure whether you need to register, the cost of checking is far lower than the cost of a missed deadline.
