Estimate UAE corporate tax on business profits, apply the AED 375,000 zero-rate band, test Small Business Relief, and understand how expenses, free-zone income, tax losses, and foreign tax credits affect your final payable amount.
The UAE Corporate Tax system has changed the way companies, freelancers, consultants, mainland businesses, and free-zone entities plan their annual profit. The headline rate is still simple when compared with many countries: most taxable profits up to AED 375,000 are taxed at 0%, while taxable profits above that level are generally taxed at 9%. The challenge is not the percentage alone. The real question is what counts as taxable income after accounting adjustments, exempt income, allowable expenses, disallowed expenses, carried-forward losses, foreign tax credits, and reliefs.
This UAE Corporate Tax Calculator is built as a practical planning tool for 2026. It helps business owners estimate corporate tax before filing, compare relief scenarios, and see whether their cash flow can handle the tax payable at the end of the year. It is not a replacement for a licensed tax adviser or the Federal Tax Authority portal, but it gives you a clear, fast estimate using the core rules every UAE business should understand.
Enter your revenue, expenses, adjustments, relief options, and credits to estimate your UAE Corporate Tax liability for the year.
This calculator is for planning only. Free-zone treatment, exempt income, transfer pricing, interest deductions, tax losses, and relief elections may require professional review.
Enter your figures and tap Estimate Corporate Tax to see taxable income, tax payable, and effective rate.
A quick summary of the numbers most UAE businesses need before estimating annual tax.
The standard mainland calculation generally applies a 0% rate to taxable profits up to AED 375,000.
Taxable profits above AED 375,000 are generally taxed at 9%, after relevant adjustments and credits.
Eligible resident taxable persons with revenue not exceeding AED 3 million may elect relief for the relevant tax period.
Qualifying Free Zone Persons may access 0% on qualifying income, but non-qualifying income can still be taxed.
A simplified planning formula for normal UAE business profits.
| Step | Treatment | Why It Matters |
|---|---|---|
| Revenue less expenses | Creates accounting profit | Start from your business performance before tax adjustments. |
| Subtract exempt income | Reduces taxable base | Some qualifying dividends, gains, or relief items may not be taxable. |
| Add disallowed costs | Increases taxable base | Not every accounting expense is automatically deductible for tax. |
| Apply losses and reliefs | May reduce tax | Loss carry-forward and Small Business Relief need eligibility checks. |
| Apply rates | 0% then 9% | Only taxable income above AED 375,000 is taxed at the standard 9% rate. |
A practical explanation for UAE mainland companies, free-zone entities, SMEs, freelancers, consultants, and business owners.
Corporate tax in the UAE is designed to be broad, modern, and internationally recognisable while still remaining relatively competitive. For many small and medium businesses, the first shock is not the 9% rate itself; it is the need to prepare accounts, register correctly, keep records, understand deductible expenses, and file on time. A company that has always looked only at bank balance can no longer treat profit informally. The tax calculation starts with accounting profit, then moves through corporate tax adjustments before the final payable amount is known.
The easiest way to understand the UAE Corporate Tax Calculator is to think in layers. First, you enter revenue and ordinary business expenses. Second, you adjust for items that are exempt or not deductible. Third, you apply losses, reliefs, and any free-zone treatment. Fourth, the calculator applies the zero-rate band and the 9% standard rate. Finally, it subtracts eligible foreign tax credit to show an estimated payable figure. This structure mirrors the way business owners should think about tax planning throughout the year, not just in the month before filing.
This calculator is useful for UAE mainland companies, Dubai businesses, Abu Dhabi companies, Sharjah SMEs, free-zone entities, consultants, e-commerce sellers, agencies, contractors, professional-service firms, and natural persons carrying on taxable business activities. It is especially helpful if you want to estimate whether your profit will cross the AED 375,000 taxable profit band, whether Small Business Relief could be relevant, or how much cash to reserve for corporate tax at year-end.
It is also useful before taking business decisions. For example, a company considering a large purchase can test how deductible expenses affect taxable profit. A freelancer can compare expected profit under different pricing scenarios. A free-zone company can separate income it believes may be qualifying from income that could be non-qualifying. A growing SME can test the difference between claiming Small Business Relief and paying tax under the normal method. The numbers are estimates, but they make conversations with accountants, directors, and partners far more practical.
For the standard calculation, taxable income up to AED 375,000 is generally taxed at 0%, while taxable income above AED 375,000 is generally taxed at 9%. This means that a business with AED 500,000 of taxable income does not pay 9% on the full AED 500,000. Instead, the first AED 375,000 falls inside the zero-rate band, and only AED 125,000 is taxed at 9%. The result is AED 11,250 before any applicable credits or special rules. This is why the effective rate is often lower than 9% for businesses just above the threshold.
The calculator shows both taxable income and the portion above AED 375,000 so you can see exactly which part of your profit is exposed to the 9% rate. That split is important for budgeting. If your profit is expected to be slightly above the threshold, good recordkeeping and correct expense treatment can make a meaningful difference. If your profit is far above the threshold, the bigger planning issue becomes cash reserve, compliance, transfer pricing documentation where relevant, and whether profits are correctly classified.
Small Business Relief is designed to reduce the compliance burden for smaller resident businesses. In simple terms, eligible resident taxable persons can elect the relief for a tax period when revenue is equal to or below AED 3 million, provided the conditions are met. If the relief applies, the business is treated differently for corporate tax purposes, and the calculator shows estimated tax as zero for that period. This can be helpful for start-ups and micro businesses that are building revenue but do not yet have the administrative depth of a larger company.
However, Small Business Relief should not be treated as an automatic switch. The revenue condition must be checked for the current and previous tax periods, the election is made for the tax period, and certain entities or arrangements may not qualify. Once a taxable person exceeds the AED 3 million revenue threshold in any tax period, the relief may no longer be available. The calculator therefore marks relief as applied only when you choose it and revenue is within the threshold. It does not decide legal eligibility; it simply helps you estimate the effect if your adviser confirms you can elect it.
Free-zone companies need extra care. Many business owners hear โ0% free-zone taxโ and assume all income is automatically exempt. In reality, qualifying Free Zone Persons may access 0% on qualifying income, but income that is not qualifying can be subject to 9%. The rules involve qualifying activities, excluded activities, substance requirements, adequate documentation, and other conditions. A business with a free-zone licence should therefore avoid relying on a simple mainland calculation without reviewing whether income is qualifying, non-qualifying, or mixed.
The calculator includes a field for qualifying free-zone income so a business can model a basic split. For example, if total accounting profit is AED 900,000 and AED 400,000 is treated as qualifying free-zone income, the remaining profit may be tested under the normal threshold and 9% rate. This is a simplified planning approach only. It does not replace a proper free-zone analysis, but it helps business owners see why classification matters. A small change in the amount treated as qualifying can produce a visible change in tax payable.
Most businesses naturally think of tax from a profit-and-loss perspective: sales minus costs. That is a good starting point, but corporate tax requires attention to whether each cost is actually deductible. Ordinary business costs such as salaries, rent, software, marketing, professional fees, utilities, and supplies may be deductible when they are properly incurred for the business and supported by records. But some items may be partly deductible, not deductible, or require special treatment. Examples include certain entertainment costs, owner withdrawals, fines, penalties, non-business spending, and expenses connected to exempt income.
This is why the calculator includes an โadd-backs/disallowedโ field. If your accounting records include AED 25,000 of expenses that should not reduce taxable income, you add them back. The calculator then increases taxable income accordingly. This field is one of the most useful parts of the tool because it pushes business owners to ask the right question: โIs this a real business expense for accounting only, or is it deductible for UAE corporate tax too?โ That question is best answered with proper records and professional guidance.
Businesses subject to UAE Corporate Tax generally need to register with the Federal Tax Authority and obtain a Corporate Tax Registration Number. Filing is not optional just because the expected tax amount is low. Even a business with no tax payable may still have registration and return obligations. The tax return and payment are generally due within nine months from the end of the relevant tax period, which makes cash-flow planning essential. A company with a 31 December year-end, for example, should treat the following nine months as a planning window, not as an excuse to delay recordkeeping.
The biggest compliance mistakes are usually preventable: registering late, waiting too long to prepare accounts, mixing personal and business expenses, ignoring related-party transactions, assuming VAT registration is the same as Corporate Tax registration, or using bank deposits as a proxy for taxable income. Corporate Tax requires a clearer accounting discipline. The calculator helps with the estimate, but the actual filing process needs properly prepared financial data and supporting documents.
VAT and Corporate Tax are separate systems. VAT is charged on taxable supplies and reported through VAT returns when a business is registered. Corporate Tax is charged on taxable business profit. A company can be VAT registered and still have little or no corporate tax payable if its taxable profit is low. Another company can be outside VAT registration but still need to consider corporate tax if it carries on taxable business activity. The thresholds, calculations, returns, and cash-flow implications are different, so the two taxes should be tracked separately.
For planning purposes, do not treat VAT collected from customers as profit. VAT payable to the FTA belongs in its own liability account. Corporate tax is calculated after profit is determined. Mixing the two can make your margins look healthier than they really are and can create cash-flow problems when payment dates arrive. A good accounting system should separate sales, VAT output, VAT input, expenses, profit, and estimated corporate tax reserve.
A simple habit is to estimate tax monthly or quarterly, even if the filing deadline is annual. If your business is clearly above the AED 375,000 threshold, set aside a percentage of monthly profit in a separate account. For many normal businesses, reserving around 9% of profit above the threshold is a useful starting point, but the actual amount may be lower or higher after adjustments, reliefs, losses, credits, and free-zone rules. The calculatorโs effective tax rate helps you turn the estimate into a cash reserve plan.
For example, a company with AED 1.8 million in revenue and AED 1.05 million in deductible expenses has AED 750,000 of accounting profit. If it has AED 25,000 in add-backs and no relief, the taxable income becomes AED 775,000. The first AED 375,000 is taxed at 0%, leaving AED 400,000 taxed at 9%, or AED 36,000 before credits. That is not devastating, but it is large enough to cause stress if the company spends all cash as soon as it arrives.
Use the output as a planning estimate, not as a final tax return. The calculator is intentionally transparent: it shows the accounting profit, taxable income, amount taxed above AED 375,000, tax before credits, estimated payable amount, and effective tax rate. That gives you a strong starting point for budgeting and adviser discussions. Before filing, confirm the treatment of exempt income, loss relief, related-party transactions, free-zone income, financing costs, foreign tax credit, and any relief election. Good tax planning in the UAE is not about avoiding tax; it is about calculating it correctly, paying on time, and keeping enough documentation to support your position if the FTA ever asks.
Use this list before finalising your UAE Corporate Tax estimate.
1. Confirm your tax period. Check whether your financial year is calendar-year or another approved accounting period, because filing and payment deadlines are calculated from the end of that period.
2. Reconcile revenue. Make sure invoiced sales, bank deposits, payment gateways, marketplace receipts, and credit notes agree with your accounting records.
3. Review expenses. Separate ordinary business costs from personal expenses, owner withdrawals, non-deductible items, and expenses connected to exempt income.
4. Identify reliefs. Check whether Small Business Relief, loss relief, free-zone treatment, or exempt income provisions are relevant before estimating tax payable.
5. Prepare documentation. Keep invoices, contracts, bank statements, payroll records, free-zone documents, transfer pricing files where needed, and evidence for any credits or exemptions.
6. Reserve cash. Set aside funds during the year so corporate tax payment does not disrupt supplier payments, salaries, rent, or working capital.
Quick answers to common questions from UAE business owners and freelancers.
For most standard taxable business income, the UAE applies 0% on taxable profits up to AED 375,000 and 9% on taxable profits above AED 375,000. Qualifying Free Zone Persons may have different treatment for qualifying income, and some exempt or special cases require separate analysis.
Corporate tax is based on taxable income, not gross revenue. You start with accounting profit, then adjust for exempt income, deductible expenses, disallowed costs, losses, credits, and reliefs. Revenue still matters for relief thresholds, especially Small Business Relief.
Small Business Relief may be available to eligible resident taxable persons when revenue is equal to or below AED 3 million in the relevant and previous tax periods. The election and eligibility conditions must be checked for each period, so it should not be assumed automatically.
Not always. A qualifying Free Zone Person may benefit from 0% on qualifying income, but non-qualifying income can be taxed at 9%. Free-zone businesses should review qualifying activities, substance, documentation, and transaction types before relying on a 0% outcome.
A taxable person generally files the corporate tax return and settles payable tax within nine months from the end of the relevant tax period. Businesses should still check their specific FTA registration and filing requirements because deadlines can depend on the entity and tax period.
No. VAT is charged on taxable supplies and reported through VAT returns. Corporate Tax is charged on taxable business profit. A business may need to track both, but they use different calculations, thresholds, returns, and payment cycles.
No. Many ordinary business expenses may be deductible, but some costs can be disallowed, restricted, or connected to exempt income. Keep invoices and records, separate personal spending, and review items such as entertainment, fines, owner withdrawals, financing costs, and related-party payments.
No. It is an estimate for planning and education. Use it to understand likely tax payable, then confirm final figures with your accountant, tax adviser, and the official FTA filing process before submitting any return.
