What is UAE corporate tax?

UAE corporate tax is a direct tax on the profit your business makes. It applies to what's left after you take your business income and subtract your allowable costs, so it's a tax on profit rather than on everything you sell.

That's the main difference between corporate tax and VAT. VAT is a tax on sales that you collect from customers and pass on, while corporate tax is charged on your business profit at the end of your tax period. You can look after both, and it helps to keep them clear in your mind.

Corporate tax took effect for tax periods starting on or after 1 June 2023, and it's overseen by the Federal Tax Authority (FTA). You can read the full overview on the Ministry of Finance corporate tax page for the official details.

How much is UAE corporate tax?

UAE corporate tax is 0% on taxable income up to AED 375,000 and 9% on taxable income above AED 375,000. The headline rate is simple, and for many small businesses it works out lower than you might expect.

The rate is charged on your taxable income, which is your business profit after allowable deductions. Corporate tax is charged in two bands based on that figure.

• 0% band: You pay no corporate tax on taxable income up to AED 375,000.
• 9% band: You pay 9% corporate tax on taxable income above AED 375,000.

Here's a plain example. Say your business has a taxable income of AED 500,000 for the year.

The first AED 375,000 is taxed at 0%, so that part costs you nothing. The remaining AED 125,000 is taxed at 9%, which comes to AED 11,250. That's your corporate tax for the year.

Qualifying income earned by a free zone business can also be taxed at 0%, as long as the business meets the conditions for that treatment.

You may have seen mention of a 15% domestic minimum top-up tax. That one applies only to very large multinational groups, so a typical small business sits outside its scope.

Does UAE corporate tax apply to your business?

Most businesses in the UAE fall within corporate tax, but the way it applies depends on how you're set up. Understanding your position helps you register correctly and file with confidence.

• Companies: UAE companies are within the scope of corporate tax on their business profit.
• Individuals (natural persons): If you run a business in your own name, corporate tax applies only when your business turnover is more than AED 1,000,000 in a calendar year.
• Free zone businesses: A free zone business may qualify for 0% on its qualifying income, but it still has corporate tax obligations, including registering and filing.

Some income sits outside corporate tax altogether. Salary and other employment income isn't taxed, and neither is income from personal investments or personal real estate that you hold outside a business.

What is Small Business Relief?

Small Business Relief is a measure that can bring your corporate tax down to nothing, and it now runs until the end of 2029. It's designed to ease the load on smaller businesses while they get used to the new system.

If you're a resident business with revenue of AED 3,000,000 or less in this and every previous tax period, you can elect to be treated as having no taxable income for that tax period, which effectively means a 0% outcome. You choose it per tax period, so you decide each year whether to claim it.

On 7 August 2026, the Ministry of Finance announced Ministerial Decision No. 131 of 2026. It extends the relief to tax periods ending on or before 31 December 2029. The AED 3,000,000 revenue threshold stays the same. You can find out how to elect Small Business Relief before your next return is due.

You still need to register for corporate tax and file your return, even when you claim the relief. It isn't open to free zone persons or to members of large multinational groups. The FTA Small Business Relief page sets out the conditions in full.

How to register for UAE corporate tax

Registration is handled online through EmaraTax, the FTA's digital tax platform. The steps below walk you through it from start to finish.

1. Create or log in to your EmaraTax account

Go to EmaraTax and sign in with your existing details, or set up a new account if you don't have one yet. This is where you'll manage your corporate tax and any other UAE tax obligations in one place.

2. Add your business and open the corporate tax registration

Add your business to your account, then open the corporate tax registration from your dashboard. This tells the FTA which entity you're registering.

3. Complete the form and upload your trade licence and details

Fill in the registration form with your business information and upload your trade licence along with any other documents requested. Take your time here so the details match your official records.

4. Submit and receive your Corporate Tax Registration Number

Once you've checked everything, submit the form. When it's approved, you'll receive your Corporate Tax Registration Number, which confirms you're registered and ready to file.

Corporate tax deadlines and penalties

Meeting your dates is the easiest way to avoid extra costs. There are two things to stay on top of: registering on time and filing on time.

Register within the deadline the FTA sets for your business. After that, you file your corporate tax return and pay any tax due within nine months of the end of your tax period. So if your year-end is 31 December 2026, your return and payment are due by 30 September 2027.

Missing these dates can add up. Late registration carries a penalty of AED 10,000, and other penalties can apply for filing or paying late. Putting reminders in place well ahead of your deadlines keeps you clear of them.

Getting your business ready for corporate tax

Good habits through the year make corporate tax far less stressful when your deadline comes round. A little organisation now saves you a scramble later, and you don't need to be an accountant to get it right. Here are some tips you can use:

• Keep accurate records. Hold on to your invoices, receipts, and statements so your figures are easy to back up.
• Separate business and personal finances. Use a dedicated business account so your profit is simple to work out.
• Track income and expenses. Record money in and money out as you go, rather than leaving it to the end of the year.
• Stay organised with cloud software. Keep your numbers in one place so you're ready to file at any time.

Moving your books to cloud accounting software makes each of these habits easier to keep. When you reconcile bank transactions regularly, your records stay current and your taxable profit is always close at hand.

FAQs on UAE corporate tax

Here are quick answers to questions small business owners might ask about UAE corporate tax.

Who has to pay corporate tax in the UAE?

Companies pay on their business profit, and individuals pay only if their business turnover is more than AED 1,000,000 in a calendar year. Salary, personal investments, and personal real estate stay out of scope.

Do small businesses pay corporate tax in the UAE?

Many pay nothing, either because their profit sits under AED 375,000 or because they claim Small Business Relief. They still need to register and file, though.

What's the difference between VAT and corporate tax?

VAT is a tax on sales that you collect from customers, while corporate tax is charged on your business profit. They're separate obligations that you manage alongside each other.

Do you still need to register if you qualify for Small Business Relief?

Yes. You must register for corporate tax and file your return to claim the relief, even though it brings your taxable income to nil.

When is the UAE corporate tax return due?

You file your return and pay any tax due within nine months of the end of your tax period. For a year-end of 31 December 2026, both are due by 30 September 2027.

Do loss-making businesses need to file?

Yes, registered businesses must file a return every tax period, even when they make a loss. Filing records your tax loss, which you can carry forward against future taxable income, capped at 75% of taxable income in any later period.
