What 9% Actually Costs on Real Numbers
Ask most UAE business owners what corporate tax will cost them and you get a version of the same calculation. Take the profit, multiply by nine per cent.
Nobody pays that. The first slice of profit is taxed at nothing at all, so the real rate is always lower than the headline, and at the profit levels most owner-run businesses operate at it is a good deal lower.
That gap is worth quantifying, because decisions get made on the wrong number surprisingly often.
First, what this tax is not
One clarification before any arithmetic, because the words cause more confusion than the rules do.
This is corporate tax. It is charged on the profit of the company. The UAE has no personal income tax, so nothing here touches your salary, your dividends or what you draw for yourself. If you have moved from a country with income tax, that instinct is the thing to set aside.
You will see the phrase taxable income throughout, including in the return itself. It does not mean your income. It means the company’s profit, after its costs, adjusted for a handful of tax rules. Read it as taxable profit every time and you will not go wrong.
Which leads to the second point. This is a tax on what is left, not on what comes in. Revenue is not the base. Your costs come off first, and only what remains is exposed.
What the rate actually is
Two brackets, and only two.
- 0% on taxable income up to AED 375,000
- 9% on taxable income above AED 375,000
The 9% applies only to the part above the threshold. It is not a cliff where crossing AED 375,000 taxes the whole amount. A business at AED 380,000 of taxable income pays 9% of AED 5,000, which is AED 450.
That is the most common misunderstanding here, and it drives some poor year end decisions.
What the effective rate works out to
Here is the arithmetic on figures that look like real businesses rather than textbook examples.
| Taxable income | Tax at 9% above AED 375,000 | Effective rate |
|---|---|---|
| AED 400,000 | AED 2,250 | 0.6% |
| AED 500,000 | AED 11,250 | 2.3% |
| AED 750,000 | AED 33,750 | 4.5% |
| AED 1,000,000 | AED 56,250 | 5.6% |
| AED 2,000,000 | AED 146,250 | 7.3% |
| AED 5,000,000 | AED 416,250 | 8.3% |
The effective rate climbs towards 9% and never arrives, because that first AED 375,000 stays untaxed no matter how large the company gets.
That untaxed slice is worth AED 33,750 to every business that reaches the threshold. Not a percentage, a flat amount, and the same flat amount whether the company makes AED 400,000 or AED 40 million. On a small profit it is most of the bill. On a large one it barely registers, which is why the effective rate keeps climbing.
For a business making AED 750,000 of taxable income, the whole annual corporate tax bill is around AED 33,750. That is a real cost. It is not the number most owners have in their heads when they picture nine per cent.
Your accounting profit is not the taxable figure
The table above starts from taxable profit, and that is not the same as the profit line at the bottom of your accounts.
Taxable income begins with accounting profit and is then adjusted. Some expenses are disallowed in whole or in part. Some income is treated differently. Payments to owners and directors are deductible only up to market value, which we cover in the rule about paying yourself. Entertainment, fines and certain other categories have their own treatment, set out in which expenses actually reduce your tax.
The practical consequence is that the taxable figure is usually higher than the profit in the accounts, sometimes by a meaningful margin. An owner estimating from management accounts is generally estimating low, and how far low depends entirely on what sits inside the expense lines.
A worked example of the gap
Take a business with AED 1.2 million of accounting profit. The instinct is to reach for the table above, find the AED 1 million row, and expect something near AED 74,000.
Now add the adjustments a real business tends to carry. Suppose AED 180,000 of the expenses turn out not to be deductible in full, made up of an owner payment above market value, some entertainment costs and a fine. Taxable income becomes AED 1,380,000 rather than AED 1,200,000.
The tax is 9% of AED 1,005,000, which is AED 90,450. Roughly AED 16,000 more than the profit line suggested, discovered while the return is being finalised rather than when there was time to plan.
Nothing there is unusual. It is why the answer has to come from finished books rather than a mental multiplication.
The cash timing nobody plans for
The payment falls due nine months after the year it relates to. For a 31 December 2025 year end that was 30 September 2026, by which point the money has usually been spent, reinvested or drawn. The bill arrives against a bank balance from a different year.
Modest as a percentage. Less modest as an unbudgeted payment. Knowing the figure in February rather than September is the difference between a transfer and a scramble, and the sum is no harder to do early.
The businesses that will notice a change
For one group the arithmetic above has been academic. Small Business Relief lets a resident business with revenue of AED 3 million or less elect to be treated as having no taxable profit, so the answer was simply nil.
That relief runs until 31 December 2026, and the transition is usually imagined as worse than it is. Take a business with AED 2.5 million of revenue and AED 600,000 of taxable profit. Under the relief it pays nothing. Without it, 9% of AED 225,000, which is AED 20,250. An effective rate of 3.4%.
Worth planning for. Not the cliff the phrase suggests. What its ending means in practice is a separate piece.
One condition is not intuitive. If revenue exceeded AED 3 million in a prior period the relief is gone, so a single strong year reaches beyond itself.
Where the free zone rules sit
A company meeting the free zone qualifying conditions is taxed under a separate framework, so none of the above is its operative calculation. Fail those conditions and it does not land somewhere comfortable. It pays 9% on its full profit for that period and the four that follow, which is why what the conditions actually require is worth reading properly.
What business owners should focus on
Work out your own number rather than the rate. The rate is 9%. Your cost is a figure in dirhams, and the table above turns one into the other in about a minute once taxable income is known.
Find out how far taxable income sits from accounting profit. That distance is where the surprise lives. It is knowable, and it is specific to your expense mix rather than general.
Stop treating the threshold as a cliff. It is not one. Decisions taken in December to stay under AED 375,000 usually cost more than the tax they avoid.
Do the arithmetic long before the deadline, not inside it. The 30 September 2026 deadline for a 31 December 2025 year end has now passed, so the live question is the year currently running. Nine months from your own year end is the rule, and knowing the figure eight months out is what turns it into a payment rather than a problem.
What the table does not include
Everything above is the ordinary calculation, and the ordinary calculation is not the whole picture. Three things sit outside it.
Costs come off first. Every figure in the table is profit after your business expenses, not revenue. What you spend running the company reduces the base before the rate touches it.
Exemptions exist. Some businesses are outside corporate tax altogether rather than inside it at 0%. Government entities, extractive businesses, qualifying public benefit entities, qualifying investment funds and pension funds each have their own treatment. That is a different thing from a rate, and it is worth knowing which side of the line you are on.
Reliefs and regimes sit on top. Small Business Relief while it lasts, the free zone rules, group relief and loss carry forward all change the answer. The table is the default, not the ceiling and not the floor.
So treat the numbers here as the shape of the thing rather than as your bill. The shape is useful, because it corrects the instinct that 9% of profit is what leaves the business. Your actual figure needs your own accounts.
Frequently asked questions
What is the UAE corporate tax rate? 0% on taxable income up to AED 375,000 and 9% on taxable income above that. The 9% applies only to the part above the threshold, not to the whole amount.
How much corporate tax do I pay on AED 1 million of profit? If taxable income is AED 1 million, tax is 9% of the AED 625,000 above the threshold, which is AED 56,250. That is an effective rate of about 5.6%.
Is corporate tax charged on revenue or profit? On taxable income, which starts from accounting profit and is then adjusted. Revenue is not the base, and accounting profit is not quite the base either.
What is the effective corporate tax rate in the UAE? It rises with income and never reaches 9%. At AED 500,000 of taxable income it is about 2.3%, at AED 2 million about 7.3%, and at AED 5 million about 8.3%.
What happens when Small Business Relief ends? The relief runs until 31 December 2026. After it ends, businesses that were relying on it return to the ordinary structure, which still gives 0% on the first AED 375,000 of taxable income.
Does the AED 375,000 threshold apply to every company? It applies to the ordinary corporate tax calculation. Free zone companies meeting the qualifying conditions are taxed under a different set of rules, so the threshold is not the operative number for them.
A number, not a mood
Corporate tax arrived in the UAE recently enough that it still gets discussed as a development rather than as a line item. On the numbers above it is a line item, and for most owner-run businesses a smaller one than the headline rate implies.
