Here is a question that surprises many business owners: if your company earned AED 2 million this year, how much of that will actually be taxed?

The honest answer is: it depends. Since UAE Corporate Tax arrived under Federal Decree-Law No. 47 of 2022, businesses have had to learn that revenue, accounting profit and taxable income are three very different things. The headline rate of 9% on taxable income above AED 375,000 is simple enough. Working out what that 9% actually applies to is where the real thinking begins.

This article does not try to give you a complete checklist. Instead, it explores how the law approaches income, the main areas where income may fall outside the tax net, and the questions every business should be asking before it files.

It starts with profit, not revenue

Corporate Tax is not charged on what you sell. The starting point is the accounting net profit or loss in your financial statements, generally prepared under IFRS. From there, the law asks you to make a series of adjustments. In broad terms:

Taxable Income = Accounting Profit + Non-Deductible Expenses − Exempt Income ± Other Tax Adjustments

That formula looks tidy on paper. In practice, each part of it invites a question. Which expenses does the law disallow? Which income can be removed? And which adjustments apply to your particular structure? The answers are rarely the same for any two businesses.

So what is usually taxable?

For a Resident Person, meaning a company incorporated in the UAE or effectively managed and controlled here, Corporate Tax applies to worldwide business income. For most businesses, that will include the everyday income from trading, such as sales of goods, services and professional fees.

It can also reach income that is easier to overlook. Gains on selling business assets, profits from overseas branches, and the non-qualifying income of a Free Zone company may all come into the calculation, depending on the facts. For Free Zone businesses in particular, whether income is "qualifying" or not, and whether the de minimis limits under Article 18 are respected, can change the outcome significantly.

Where income may fall outside the net

The law deliberately removes certain income from tax, mainly to avoid taxing the same profit twice and to keep the UAE attractive as a holding and investment location. Some of the areas worth exploring include:

•       Dividends from UAE companies. These are generally exempt.

•       The Participation Exemption (Article 23). Dividends and gains from qualifying shareholdings, including foreign ones, may be exempt. Whether a holding qualifies depends on conditions such as ownership percentage or acquisition cost, holding period and the tax treatment of the investee.

•       Foreign branch profits (Article 24). A Resident Person may elect to exempt the profits of a Foreign Permanent Establishment. It is a choice with consequences, because foreign branch losses then generally cannot be used in the UAE either.

•       International shipping and aviation (Article 25). Certain income of Non-Resident Persons from operating ships or aircraft in international transport may be exempt where the conditions are met.

•       Qualifying Free Zone income. This may be taxed at 0%, provided the substance, activity and other conditions are satisfied.

None of these is automatic. Each one comes with conditions, and the details matter. A shareholding that qualifies this year may not qualify next year if circumstances change.

What about individuals?

For individuals, the line is drawn around business activity. Salaries and employment income are outside the scope of Corporate Tax. Income from personal real estate investments and personal investments in shares, held in a private capacity, is also generally outside the scope. The picture can change once an individual's activities start to look like a business, and that boundary is not always obvious.

Thresholds and reliefs worth knowing

Two reliefs often shape the final result. First, the first AED 375,000 of taxable income is taxed at 0%, with 9% applying only to the amount above it. Second, Small Business Relief allows eligible resident businesses with revenue of AED 3 million or less to elect to be treated as having no taxable income, for tax periods ending on or before 31 December 2026 as the law currently stands. It is not available to everyone, including Qualifying Free Zone Persons and members of large multinational groups, so eligibility should be checked.

There is also a quieter rule that is easy to miss. If income is exempt, the expenses incurred to earn it are generally not deductible. Claiming an exemption therefore often means revisiting your cost allocations too.

The questions to keep asking

Rather than ending with a rulebook, it may be more useful to end with a few questions:

•       Do you know where each of your income streams actually comes from, and how the law classifies it?

•       Have you tested your exemptions against the conditions, or simply assumed they apply?

•       If you operate in a Free Zone, do you know which of your income is qualifying, and by how much?

•       Are the costs linked to exempt income being treated correctly?

•       Will the answers still be the same next year, as your business, structure and the law continue to evolve?

UAE Corporate Tax is still young, and guidance from the Federal Tax Authority continues to develop. The distinction between taxable and non-taxable income is not a one-time exercise but an ongoing conversation between your business, your advisers and the law. The businesses that keep asking the right questions are usually the ones that get the answers right.
