UAE Corporate Tax for SMEs: Rates, Deadlines and the Small Business Relief Extension

UAE Corporate Tax is charged at 0% on the first AED 375,000 of taxable profit and 9% above that. Registration is mandatory for almost every business, and returns are due within nine months of your financial year end. Small Business Relief, which can bring the effective rate to nil for businesses under AED 3 million in revenue, now runs to 31 December 2029.

Corporate Tax is still the topic that comes up most on our first calls with business owners. Two years in, plenty of UAE SMEs are still unsure what they owe, what they need to file, and whether the reliefs they have heard about apply to them. This is a plain-English guide to the parts that matter, updated for the change the Ministry of Finance made this summer.

How much is UAE Corporate Tax?

UAE Corporate Tax is charged at two rates. You pay 0% on the first AED 375,000 of taxable profit, and 9% on taxable profit above that. Taxable profit is not the same as revenue: it is broadly your accounting profit after allowable adjustments, not the money that comes through the door.

A worked example. If your business makes AED 500,000 in taxable profit for the year, the first AED 375,000 is taxed at 0% and the remaining AED 125,000 is taxed at 9%. That is AED 11,250 of Corporate Tax. The rate is low by international standards, but the filing obligations are real, and that is where most owners get caught out.

Who has to register for Corporate Tax?

Almost every business in the UAE. Registration with the Federal Tax Authority is mandatory for taxable persons, including mainland companies and free zone companies, whether or not you expect to pay any tax. A new business generally needs to register within three months of incorporation.

This is the point worth underlining: registration is separate from paying. A business can owe nothing and still be required to register and file. Missing the registration deadline carries an administrative penalty of AED 10,000, so it is not a step to leave until later.

There is some relief for first-time filers. The Federal Tax Authority will waive or refund that AED 10,000 penalty if you file your first Corporate Tax return within seven months of the end of your first tax period, rather than the usual nine. Registering on time is still far better, but the waiver has softened the landing for businesses that were late in the first cycle. If you are unsure whether you are registered correctly, our Tax Coordination service is where we start.

When is the Corporate Tax return due?

Your return and any payment are due within nine months of the end of your tax period. For a business with a financial year ending 31 December 2025, that means the return is due by 30 September 2026.

You file even if the result is nil. A business claiming Small Business Relief, or sitting entirely within the 0% band, still submits a return. The filing is the obligation, not just the payment.

The 2026 update: Small Business Relief extended to 2029

Here is the change that matters this year. Small Business Relief lets a UAE resident business with revenue of AED 3 million or less elect to be treated as having no taxable income for that period, which brings its Corporate Tax to nil.

The relief was originally set to end after tax periods finishing on 31 December 2026. In July 2026, the Ministry of Finance issued Ministerial Decision No. 131 of 2026 and extended it. The AED 3 million revenue threshold is unchanged, but the relief now applies to tax periods ending on or before 31 December 2029. That gives smaller businesses three more years of breathing room.

Two things to keep in mind. First, the relief is not automatic: you have to elect for it on your Corporate Tax return, so you still register and file. Second, the AED 3 million test applies to the current period and every previous one, and electing for relief in a period means you cannot carry forward tax losses or certain deductions from that period. It is a genuine benefit for smaller businesses, but it is a decision to make with your numbers in front of you, not a default.

What about free zone companies?

Free zone businesses are not automatically exempt. A Qualifying Free Zone Person can access a 0% rate on qualifying income if it meets the conditions, but it must still register and file like everyone else. Assuming your free zone licence means you can ignore Corporate Tax is one of the more expensive misunderstandings we see. If you operate from a free zone, get your qualifying income position confirmed rather than assumed.

What you actually need in place

Corporate Tax is only as clean as the accounts underneath it. To file with confidence you need accurate, up to date books and a proper set of financial statements. If your bookkeeping is behind, or your numbers have never been pulled into real financial statements, that is the work to sort first.

This is the everyday work we do for SMEs: keeping the books right through our accounting and bookkeeping service, turning them into clear financial statements and reporting, and making sure everything is audit ready when it needs to be.
