UAE Corporate Tax Calculator 2026: Work Out 9%

How Do You Calculate UAE Corporate Tax in 2026?

To calculate UAE corporate tax in 2026, take your taxable income, apply 0% to the first AED 375,000 and 9% to everything above it. The formula is: (taxable income − 375,000) × 0.09, used only when taxable income exceeds the threshold. Worked example: a business with AED 600,000 of taxable income pays 9% on the AED 225,000 above the threshold, which is AED 20,250, while the first AED 375,000 is taxed at zero. The protected band means small and emerging companies carry little or no corporate tax, and only the portion of profit above AED 375,000 ever attracts the 9% rate. Always confirm current rates with the Federal Tax Authority before you file.

This is, in essence, the entire UAE corporate tax calculator in one line. There is no complicated rate ladder, no progressive scale that climbs with size, and no surprise surcharge that kicks in at higher profits for ordinary businesses. There is one threshold, AED 375,000, one headline rate, 9%, and a clean marginal structure that protects the first slice of profit completely. The hard part of any real calculation is almost never the arithmetic at the end; it is arriving at the correct taxable income to put into the formula in the first place. That is where the genuine work lives, and it is where most of this guide is spent. At Noble Core Ventures we walk founders through that process every week, and the pattern is always the same: get the taxable income right, and the 9% sum is trivial.

This page is a content calculator, not a black-box widget. The aim is to show you the exact method, the formula, and a series of worked examples at different profit levels so you can reproduce the number yourself and understand precisely why it lands where it does. We will cover the standard zero-and-nine structure, small business relief that can take eligible companies to nil, the Qualifying Free Zone Person route that splits income into two streams, and the common mistakes that quietly inflate the figure people calculate by hand. Every number that follows is illustrative for 2026 planning; the official rates, the AED 375,000 threshold and the 9% rate above it are published by the Ministry of Finance and administered by the Federal Tax Authority, and you should always confirm the current position with the authority before relying on any figure.

The UAE Corporate Tax Formula, Step by Step

The corporate tax calculation runs in a clear sequence, and it is worth internalising the order because skipping a step is how people arrive at the wrong answer. The first step is to calculate your accounting net profit: total revenue for the financial year minus the cost of generating that revenue and your operating expenses. This is the profit figure your accountant produces for the year, the bottom line of your income statement. It is not your revenue, and it is not the cash in your bank account; it is what is left after the genuine, allowable costs of running the business have been deducted.

The second step is to adjust that accounting profit to reach taxable income. The corporate tax rules do not simply tax the accounting bottom line as-is. Some expenses you recorded for accounting purposes are not fully deductible for tax, so they get added back; certain types of income may be exempt and are taken out; and specific adjustments are required by the law. The result of these adjustments is your taxable income, and it is this figure, not raw accounting profit, that you feed into the rate formula. For many straightforward small businesses the two numbers are close, but the distinction matters enormously the moment you have non-deductible items, exempt dividends, or free zone qualifying income in the mix.

The third step is the rate application, and this is the simple part. You take your taxable income and apply the band structure. Anything up to AED 375,000 is taxed at 0%. Anything above AED 375,000 is taxed at 9%. Expressed as a single formula for a business over the threshold, your corporate tax payable equals (taxable income − 375,000) multiplied by 0.09. If your taxable income is AED 375,000 or less, your corporate tax payable is simply nil, because the entire amount falls inside the zero-rated band. The fourth and final step, where relevant, is to apply any relief you are eligible for and have elected, such as Small Business Relief, which can reduce an otherwise-positive liability to nil. We will see each of these in action in the worked examples below.

Worked Example One: A Business Below the Threshold

Consider a small consultancy with a financial year of revenue totalling AED 520,000. Its allowable expenses, salaries, office costs, software, marketing and professional fees, come to AED 180,000. The accounting net profit is therefore AED 520,000 minus AED 180,000, which equals AED 340,000. Assume there are no tax adjustments to make, so taxable income also equals AED 340,000. Now apply the formula. Because AED 340,000 is below the AED 375,000 threshold, the entire amount sits inside the 0% band. The corporate tax payable is nil. Not a reduced amount, not a token sum, but genuinely zero.

This example illustrates the most important practical feature of the UAE structure for the typical founder: a great many small businesses owe no corporate tax at all, purely because of the band design, before any relief is even considered. The AED 375,000 zero-rated threshold is generous relative to the profit of a young or modest company, and it means the question for many owners is not "how much tax will I pay" but "am I anywhere near the threshold yet." That said, owing nil tax does not automatically mean you can ignore the system. Most taxable persons are still required to register through EmaraTax and file a return, even in a year where the calculation produces zero. The obligation to register and file is separate from the obligation to pay, and treating "nil tax" as "nothing to do" is one of the costliest assumptions a new business can make.

Worked Example Two: A Business Just Over the Threshold

Now take a trading company with taxable income of AED 500,000 after all expenses and adjustments. This sits above the threshold, so the marginal structure comes into play. The first AED 375,000 is taxed at 0%, contributing nothing. The remaining AED 125,000, the amount above the threshold, is taxed at 9%. Nine percent of AED 125,000 is AED 11,250. That is the total corporate tax payable. Notice what did not happen: the business was not taxed 9% on the whole AED 500,000, which would have been AED 45,000. The protected first band saved it AED 33,750 compared to a flat-rate system. This is the essence of a marginal band: only the slice above the line is taxed at the higher rate.

It is worth pausing on the effective rate here, because it surprises people. This company's total tax of AED 11,250 on taxable income of AED 500,000 is an effective rate of just 2.25%, even though the headline rate is 9%. The effective rate is always lower than the headline rate because of the zero-rated first AED 375,000, and it rises gradually toward 9% as taxable income grows and the protected band becomes a smaller proportion of the total. A business at AED 500,000 has an effective rate of 2.25%; the same business at AED 1,000,000 would have a meaningfully higher effective rate, as we will see next. Understanding this curve helps founders plan, because it shows that the marginal impact of additional profit is what matters, not a flat slice off the top.

Worked Example Three: A Larger Profit and the Effective Rate

Take a more established company with taxable income of AED 1,200,000 for the year. Apply the formula directly: taxable income minus the threshold is AED 1,200,000 minus AED 375,000, which equals AED 825,000. Multiply that by 9%, and you get AED 74,250. So the corporate tax payable is AED 74,250, and the first AED 375,000 of profit again escapes tax entirely. The effective rate here is AED 74,250 divided by AED 1,200,000, which works out to roughly 6.19%. Compare that with the 2.25% effective rate from the previous example: as profit rises, the fixed AED 375,000 shelter becomes proportionally smaller, so the effective rate climbs toward, but never quite reaches, the 9% headline.

This pattern continues predictably. A company with AED 5,000,000 of taxable income would pay 9% on AED 4,625,000, which is AED 416,250, an effective rate of about 8.33%. A company with AED 10,000,000 of taxable income would pay 9% on AED 9,625,000, which is AED 866,250, an effective rate of about 8.66%. The larger the profit, the closer the effective rate edges to 9%, because the AED 375,000 free band is diluted across a bigger base. For planning purposes this means a profitable, scaling business should budget for something close to, but slightly under, 9% of its taxable income, while a smaller business should expect a much lower effective figure. Note that very large multinational groups within the scope of global minimum tax frameworks may be subject to different rules and a different effective rate, so groups of that size should confirm their specific position rather than relying on the standard structure.

UAE Corporate Tax Rates and Thresholds 2026 (Indicative)

The table below summarises the headline structure for 2026 planning. The AED 375,000 threshold and the 0%/9% rates are part of the published federal framework; the Small Business Relief cap and the QFZP treatment are subject to conditions and can be updated, so treat the relief figures as indicative and confirm current rates with the authority before filing.

Confirm current rates, thresholds and reliefs with the authority, as figures and conditions can change. The figures above are intended to help you reproduce the calculator method, not to replace official guidance from the Federal Tax Authority at tax.gov.ae or the Ministry of Finance.

How Small Business Relief Changes the Calculation

Small Business Relief is the single most powerful lever available to genuinely small companies, and it changes the calculation from "9% on the excess" to, potentially, "nil." Under the relief, an eligible resident business whose revenue for the tax period is at or below the stated cap, commonly cited as AED 3 million, can elect to be treated as having no taxable income for that period. The effect is that even if the business made a healthy profit that would normally attract 9% on the amount above AED 375,000, the election can bring the payable down to zero. It is important to be precise about the trigger: the relief is tested against revenue, not profit, which is the opposite basis to the AED 375,000 band. So a business with high revenue but modest profit might be over the relief cap yet still owe very little under the standard band, while a business with low revenue and high margins might qualify for relief and pay nothing despite a strong profit.

Take a worked illustration. A design studio has revenue of AED 2,400,000 and, after expenses, a taxable income of AED 700,000. Under the standard calculation it would pay 9% on AED 325,000, which is AED 29,250. But because its revenue of AED 2,400,000 is at or below the AED 3 million relief cap, it may be eligible to elect Small Business Relief and be treated as having nil taxable income, reducing the payable to zero for that period. The election is not automatic; the business must claim it on its return, and the relief is time-limited and conditional under current rules. You still generally need to register and file even when you elect relief. Because the cap, the eligible periods and the precise eligibility tests can change, you should confirm them directly with the Federal Tax Authority before assuming you qualify, rather than building your cash flow around a relief you have not verified.

How the Qualifying Free Zone Person Calculation Differs

Free zone companies have an additional route that ordinary mainland businesses do not: the Qualifying Free Zone Person, or QFZP, regime. A free zone business that meets strict conditions can apply 0% corporate tax to its qualifying income and 9% only to its non-qualifying income. This turns a single calculation into a two-stream one. Instead of running every dirham of profit through the standard band, a QFZP separates income that meets the qualifying definition, which is taxed at 0%, from income that does not, which is taxed at 9%. The conditions are demanding: the business must maintain adequate substance in the free zone, earn qualifying income from qualifying activities, stay within a de minimis limit for non-qualifying revenue, prepare audited financial statements, and comply with transfer pricing rules. Fail any condition and the business can lose QFZP status, after which the standard structure applies.

A simplified worked illustration shows the mechanics. Suppose a free zone trading company has total income that, after expenses, produces AED 900,000 of profit, of which AED 800,000 derives from qualifying activity and AED 100,000 is non-qualifying. As a QFZP, the AED 800,000 of qualifying income is taxed at 0%, and the AED 100,000 of non-qualifying income is taxed at 9%, giving AED 9,000 of corporate tax. Contrast that with the same company failing to qualify: it would instead run the full AED 900,000 through the standard band, paying 9% on AED 525,000, which is AED 47,250. The QFZP route is clearly valuable, but it is conditional and detailed, and the qualifying-income definition is the crux of the whole thing. Many founders assume "free zone equals tax-free," which is not how the regime works. The 0% is a benefit you earn by meeting conditions, not an automatic exemption, and getting the classification wrong is an expensive mistake. We strongly recommend professional verification before relying on a QFZP outcome in your calculation.

Putting It Together: A Simple Self-Calculation Method

If you want to estimate your own corporate tax before speaking to an adviser, here is the method distilled into a repeatable routine you can run on a single page. First, write down your revenue for the financial year. Second, subtract all your allowable business expenses to reach accounting net profit. Third, make a short list of anything that needs adjusting for tax, non-deductible fines, the disallowed portion of certain entertainment costs, exempt income such as qualifying dividends, and adjust your profit accordingly to reach taxable income. Fourth, check whether you might qualify for Small Business Relief, because if your revenue is at or below the cap and you elect, your payable could be nil regardless of the profit figure. Fifth, if relief does not apply, run the standard formula: taxable income minus AED 375,000, times 0.09, with a floor of zero.

Working through that routine for a representative case makes it concrete. A marketing agency has revenue of AED 1,800,000 and allowable expenses of AED 1,050,000, giving accounting net profit of AED 750,000. It has AED 20,000 of non-deductible costs to add back and no exempt income, so taxable income is AED 770,000. Its revenue of AED 1,800,000 is below the AED 3 million relief cap, so it could potentially elect Small Business Relief and pay nil for the period, subject to conditions. If, however, it chose not to or could not elect relief, the standard calculation would be AED 770,000 minus AED 375,000, which is AED 395,000, times 9%, giving AED 35,550. That single example shows both branches: the relief path to nil, and the standard path to a defined figure. The discipline of running both branches is exactly what stops founders from over- or under-estimating, and it is the heart of using this page as a real calculator rather than guessing.

It is worth stressing where the precision actually comes from. The 9% arithmetic is the easy 5% of the work; the other 95% is bookkeeping that captures every allowable expense and classifies your income correctly. A business that keeps clean records, separates VAT cash flows from income, and tracks its qualifying versus non-qualifying income through the year will calculate its corporate tax accurately and almost effortlessly. A business that leaves it all to a year-end scramble will either overpay by missing deductions or risk penalties by getting the figure wrong. The single best investment in an accurate corporate tax calculation is good monthly bookkeeping, which is exactly the foundation Noble Core Ventures helps clients put in place so the year-end number is a formality rather than a fright.

How Corporate Tax and VAT Interact in Your Numbers

A frequent source of miscalculation is mixing corporate tax and VAT, so it is worth being explicit about how they sit together. VAT is a 5% indirect tax that flows through your invoices: you charge 5% on most sales, reclaim the 5% you pay on eligible purchases, and remit the net difference to the Federal Tax Authority through quarterly or monthly returns. The VAT you collect is never your income, and the VAT you reclaim is never your expense; you are simply a collector standing between your customers and the authority. Corporate tax, by contrast, is a 9% direct tax on annual profit, calculated once a year on taxable income. The two run on different bases, different rates and different timelines, and they share only the EmaraTax portal and the same administering authority.

For the calculation this means one thing above all: keep VAT out of your taxable-income working. When you total revenue to start the corporate tax calculation, you use the net amounts excluding VAT, because the VAT element was never yours. When you total expenses, you use the net amounts excluding recoverable VAT, because you reclaimed that portion. Founders who accidentally include collected VAT as revenue inflate their taxable income and over-calculate their corporate tax; those who include reclaimable VAT as an expense distort it the other way. The cleanest approach is to keep your books on a VAT-exclusive basis for the purpose of profit measurement, so the figure that feeds your corporate tax formula is true profit and nothing else. For a fuller side-by-side, our companion guide on corporate tax versus VAT in the UAE walks through who pays each and when, and the two pages are designed to be read together.

Registration, Filing and the Deadlines Behind the Number

Calculating the right figure is only half the job; you also have to register, file and pay on time, and these obligations sit on a calendar that is independent of how much tax the calculation produces. Most taxable persons are required to register for corporate tax through the EmaraTax portal operated by the Federal Tax Authority, regardless of whether they expect to owe anything. Registration deadlines are driven by your licence and category, and missing the registration window is itself penalised, separately from any tax due. This is why a business that calculates a nil liability still cannot relax: the duty to register and file is not waived just because the number is zero.

Filing happens once per financial year, with the return and any payment generally due within nine months of the end of the relevant tax period. A company with a financial year ending 31 December 2025 would typically file and pay by 30 September 2026; one with a year ending 31 May 2026 would typically file by the end of February 2027. The nine-month window is generous compared with VAT's quarterly rhythm, but the long runway is precisely what lulls businesses into leaving everything to the last weeks, which is when errors creep in. The professional approach is to keep your books current through the year, run the calculation method on this page each quarter as a sense check, and treat the year-end filing as a confirmation of figures you already understand. The official rules, deadlines and registration steps are published by the Federal Tax Authority, and you should always confirm your specific dates with the authority or a qualified adviser, because the consequences of a missed deadline are paid in penalties rather than in tax.

Common Mistakes to Avoid

The most common mistake by far is calculating 9% on the whole of taxable income rather than only on the portion above AED 375,000. People hear "9% corporate tax" and multiply their entire profit by 0.09, which substantially overstates the bill. Remember that the first AED 375,000 is always taxed at zero, so the correct base for the 9% is taxable income minus AED 375,000, never the full figure. In the AED 500,000 example earlier, this single error would have produced AED 45,000 instead of the correct AED 11,250, a difference of nearly four times. Always subtract the threshold before applying the rate.

The second frequent error is confusing revenue with profit. The AED 375,000 band, and the corporate tax calculation generally, runs on taxable income derived from net profit, not on turnover. A business with high revenue but thin margins can owe far less than its sales suggest, while the same revenue figure is what drives the entirely separate VAT registration threshold. Mixing the two, or running the corporate tax formula on revenue, is a guaranteed way to arrive at a wildly wrong number. Always start the calculation from profit after allowable expenses, not from the top line.

A third mistake is assuming "free zone equals tax-free." The Qualifying Free Zone Person 0% rate applies only to qualifying income and only when strict conditions are met; non-qualifying income is taxed at 9%, and a company that fails the conditions reverts to the standard structure entirely. Treating a free zone licence as an automatic exemption, and therefore calculating zero tax across the board, is one of the most expensive errors a free zone founder can make. Classify your income correctly and verify your QFZP status before assuming any 0% treatment.

The fourth mistake is letting VAT contaminate the corporate tax calculation. Including collected VAT as income, or reclaimed VAT as expense, distorts taxable income and therefore the final 9% figure. Keep your profit measurement on a VAT-exclusive basis so the number you feed into the formula is true profit. The fifth and final mistake is treating a nil calculation as "nothing to do." A business that owes no corporate tax, whether because it is below the threshold, has elected Small Business Relief, or made a loss, must still generally register and file. Confusing "no tax to pay" with "no obligation" exposes the business to late-registration and late-filing penalties that have nothing to do with the tax figure itself.
