Your first UAE corporate tax return is due by 30 September 2026 if your financial year ended 31 December 2025. The tax rate itself is simple – 0% on the first AED 375,000 of taxable income, 9% on everything above. What trips most businesses up is the gap between accounting profit and taxable income. This guide closes that gap with the exact adjustment sequence the Federal Tax Authority expects, backed by three worked examples at different revenue levels.
The Five-Step Formula
Every UAE corporate tax calculation follows the same path:
Accounting net profit (per IFRS/IFRS for SMEs)
minus exempt income
plus non-deductible expenses
minus additional deductions
equals taxable income
You then apply the two-band rate: 0% up to AED 375,000, 9% above. If taxable income is AED 600,000, you pay 9% on AED 225,000 = AED 20,250. Not on the full AED 600,000.
Step 1: Start with Accounting Net Profit
Take the net profit or loss from your audited or reviewed financial statements prepared under IFRS (or IFRS for SMEs). This is the figure on line “Profit for the Period” in your income statement.
If your revenue exceeds AED 50 million, you must use IFRS. Below that threshold, IFRS for SMEs is acceptable. Either way, the starting point is the bottom-line accounting profit – not revenue, not gross profit.
Common mistake: Some businesses start with revenue and try to subtract only “tax-deductible” costs. That is not how the UAE system works. You start with accounting profit and then adjust.
Step 2: Remove Exempt Income
Certain categories of income are excluded from taxable income entirely. Remove these from your starting figure:
Qualifying dividends and profit distributions (Article 35): Dividends from UAE or foreign subsidiaries are generally exempt if you hold at least 5% ownership interest (or the investment cost is at least AED 4 million) for 12 months or more, and the subsidiary is subject to a 9% or higher tax rate. This is the “participation exemption.”
Capital gains on qualifying shareholdings (Article 23): Gains from selling shares that meet the same ownership thresholds above are also exempt.
Income from a foreign permanent establishment if you elect to exempt it (Article 24): If your UAE company has a branch overseas that pays tax there, you can elect to exclude that branch’s income entirely.
Example: Your UAE trading company earned AED 2 million net profit. AED 150,000 of that was dividends from a 20%-owned UAE subsidiary. Your adjusted starting point: AED 2,000,000 – AED 150,000 = AED 1,850,000.
Step 3: Add Back Non-Deductible Expenses
Article 33 of the Corporate Tax Law lists expenditures that cannot reduce your taxable income, even if they appear in your income statement. Add these back:
Fully non-deductible (add back 100%):
- Fines and penalties imposed by UAE government authorities (traffic fines, FTA penalties, municipality violations)
- Bribes, illegal payments, or expenditure connected to unlawful activity
- Donations to non-qualifying entities (only donations to Cabinet-approved public benefit entities qualify)
- Corporate tax itself – you cannot deduct your own tax liability
- Dividends, profit distributions, or owner drawings booked as expenses
- Provisions for doubtful debts that are general in nature (only specific, clearly identified bad debts are deductible)
- Expenditure not incurred wholly and exclusively for business purposes
Partially non-deductible (add back 50%):
- Entertainment, amusement, and recreation expenses – only 50% is deductible (Article 33). This covers client dinners, team outings, event tickets, and hospitality. Business meals during travel are generally fully deductible as travel expenses, not entertainment.
Interest limitation (Article 30): Net interest expenditure exceeding the higher of AED 12 million or 30% of tax-adjusted EBITDA must be added back. Any disallowed interest carries forward for up to 10 years. For most SMEs with interest costs well below AED 12 million, this rule has no practical impact.
Related party transactions (Article 34-35): If you transacted with related parties at prices that do not reflect arm’s length terms, the FTA can adjust the amounts. Maintain transfer pricing documentation – especially if related party transactions exceed AED 40 million.
Example: Your income statement shows AED 45,000 in client entertainment, AED 8,000 in traffic and municipality fines, and AED 15,000 donated to a friend’s charity (not Cabinet-approved). Add back: AED 22,500 (50% of entertainment) + AED 8,000 (fines) + AED 15,000 (non-qualifying donation) = AED 45,500.
Step 4: Apply Tax Losses and Small Business Relief
Carry-forward losses (Article 37-39): Tax losses from previous periods can offset up to 75% of the current period’s taxable income. The remaining 25% is always taxable. Losses carry forward indefinitely, provided the same person (or same ultimate shareholders at 50%+) continues to own the business.
Small Business Relief (Article 21): If your revenue is AED 3 million or below for the current and all previous tax periods, you can elect Small Business Relief (see also: corporate tax for freelancers). This treats your taxable income as zero – no tax to pay. You must still register and file a return, but your liability is nil. This relief is available for tax periods ending on or before 31 December 2026.
Important: Small Business Relief is an election, not automatic. You must claim it in your tax return. If you do not claim it, the normal calculation applies.
Step 5: Calculate the Tax
Apply the two-band rate to your final taxable income:
- First AED 375,000: 0%
- Everything above AED 375,000: 9%
Formula: Tax = (Taxable Income – 375,000) x 9%
If taxable income is AED 375,000 or less, the tax is zero.
Worked Example 1: Small Trading Company (AED 1.2M Revenue)
Al Noor General Trading LLC, a Dubai mainland company importing electronics accessories.
| Line Item | Amount (AED) |
|---|---|
| Revenue | 1,200,000 |
| Cost of goods sold | (720,000) |
| Gross profit | 480,000 |
| Operating expenses | (280,000) |
| Net profit (accounting) | 200,000 |
Adjustments:
- Entertainment expenses in operating costs: AED 12,000 (add back 50% = AED 6,000)
- Traffic fines: AED 2,500 (add back 100%)
- All other expenses are wholly business-related
Taxable income: AED 200,000 + AED 6,000 + AED 2,500 = AED 208,500
Tax calculation: AED 208,500 is below AED 375,000, so the tax rate is 0%.
Corporate tax payable: AED 0
Alternative: This company could also elect Small Business Relief (revenue AED 1.2M < AED 3M threshold). Either way, no tax is due - but electing Small Business Relief means you skip the adjustment calculation entirely.
Worked Example 2: Professional Services Firm (AED 5M Revenue)
Morgan Advisory Consultants LLC, a DMCC free zone management consultancy.
| Line Item | Amount (AED) |
|---|---|
| Revenue (all from mainland UAE clients) | 5,000,000 |
| Staff costs | (2,200,000) |
| Rent and utilities | (480,000) |
| Travel and entertainment | (180,000) |
| Professional fees | (120,000) |
| Depreciation | (95,000) |
| Other operating expenses | (225,000) |
| Net profit (accounting) | 1,700,000 |
Adjustments:
- Entertainment portion of travel: AED 60,000 (add back 50% = AED 30,000)
- Donation to non-qualifying charity: AED 25,000 (add back 100%)
- FTA late filing penalty from a VAT return: AED 5,000 (add back 100%)
- Dividend income from a 30%-owned UAE subsidiary: AED 80,000 (exempt – subtract)
Taxable income: AED 1,700,000 + AED 30,000 + AED 25,000 + AED 5,000 – AED 80,000 = AED 1,680,000
Free zone question: This firm earns all revenue from mainland UAE clients. Under Ministerial Decision No. 265 of 2023 (see our full QFZP guide), services income from mainland clients is generally “Excluded Activity” income for a Qualifying Free Zone Person. This income would be taxed at 9%, not 0%. The firm cannot benefit from the free zone 0% rate on this income.
Tax calculation: (AED 1,680,000 – AED 375,000) x 9% = AED 117,450
Corporate tax payable: AED 117,450
Worked Example 3: Manufacturing Company with Losses Carried Forward (AED 15M Revenue)
Gulf Industrial Solutions LLC, a Sharjah manufacturer with AED 400,000 in tax losses carried forward from the previous period.
| Line Item | Amount (AED) |
|---|---|
| Revenue | 15,000,000 |
| Cost of goods sold | (9,500,000) |
| Gross profit | 5,500,000 |
| Operating expenses | (3,800,000) |
| Interest on bank loan | (320,000) |
| Net profit (accounting) | 1,380,000 |
Adjustments:
- Entertainment: AED 85,000 (add back 50% = AED 42,500)
- Municipality fine: AED 12,000 (add back 100%)
- Interest limitation check: Net interest of AED 320,000 is well below AED 12 million – no adjustment needed
- General provision for doubtful debts (not specific): AED 75,000 (add back 100%)
Pre-loss taxable income: AED 1,380,000 + AED 42,500 + AED 12,000 + AED 75,000 = AED 1,509,500
Loss offset (75% cap): Carried forward loss of AED 400,000 can offset up to 75% of AED 1,509,500 = AED 1,132,125. Since AED 400,000 is less than AED 1,132,125, the full loss is used.
Taxable income after loss: AED 1,509,500 – AED 400,000 = AED 1,109,500
Tax calculation: (AED 1,109,500 – AED 375,000) x 9% = AED 66,105
Corporate tax payable: AED 66,105
Without the loss carry-forward, tax would have been (AED 1,509,500 – AED 375,000) x 9% = AED 102,105. The carried loss saved AED 36,000 in tax.
The Adjustment Checklist Before You File
Run through this list when preparing your September 2026 return:
- Start right – use IFRS-compliant financial statements, not management accounts

- Fines and penalties – all government-imposed fines go back; contractual penalties between businesses stay deductible
- Donations – only Cabinet-approved public benefit entities qualify; all others add back
- Related parties – document arm’s length pricing for intercompany transactions
- Interest – check the AED 12M / 30% EBITDA cap (relevant only for larger businesses)
- Exempt income – remove qualifying dividends and capital gains
- Provisions – general bad debt provisions add back; specific, documented write-offs stay

When to Get Professional Help
You can handle this calculation yourself if your business has straightforward income, no related party transactions, and no cross-border operations. Bring in a tax advisor when:
- You operate in a free zone and need to determine qualifying vs. non-qualifying income
- You have intercompany transactions or related party dealings
- Your interest costs approach AED 12 million
- You have foreign income or permanent establishments abroad
- You need to decide between tax grouping and filing separately
