Introduction
The mechanics of calculating UAE corporate tax are simpler than most owners assume — but the work is in the adjustments. This walkthrough takes a fictional UAE SME, Atlas Trading LLC, through the full computation step by step, the same way an OPAB tax specialist would prepare it.
Use the structure as a template for your own working file. Numbers are illustrative; the principles apply to any mainland or free zone entity in 2026.
The Worked Example: Atlas Trading LLC
Atlas Trading LLC is a Dubai mainland trading company with FY2025 revenue of AED 8 million and accounting profit before tax of AED 1.2 million. It has one related-party loan from its UAE holding company, modest entertainment expenses, and a few items that need adjustment to reach taxable income.
Step 1: Start With Accounting Profit
Accounting profit before tax: AED 1,200,000. This is the audited or management-account profit per IFRS, before any tax adjustments. Use the final, signed-off financials — not draft numbers.
Step 2: Add Back Non-Deductible Expenses
- Entertainment expenses (50% non-deductible portion): +AED 30,000.
- Fines and penalties: +AED 5,000.
- Donations to non-qualifying organisations: +AED 10,000.
- Excess interest above the 30% EBITDA cap (where applicable): +AED 0 in this example.
Step 3: Adjust for Tax-Specific Treatments
Subtract any deductions specifically allowed under the corporate tax law that have not been reflected in the books — for example, capital allowances if claiming actuals. Add back any income items that are exempt for accounting but taxable for corporate tax purposes (rare for SMEs). Atlas has none in this period.
Step 4: Apply Elections and Reliefs
Atlas does not qualify for Small Business Relief because its revenue exceeds AED 3 million. It also does not elect the realisation basis. If Atlas were a free zone company, this is where you would apply the 0% rate to qualifying income and 9% to non-qualifying income.
Step 5: Reach Taxable Income
Taxable income = AED 1,200,000 + AED 45,000 = AED 1,245,000.
Apply the two-tier rate:
- First AED 375,000 at 0%
- Remaining AED 870,000 at 9%
Corporate tax liability = AED 78,300.
Step 6: Confirm Cash and File
Reserve the AED 78,300 in cash, schedule the EmaraTax payment three working days before the deadline, and submit the corporate tax return. Retain all working papers, invoices, and the tax computation file for at least seven years.
What Changes for a Free Zone Variant
If Atlas were a free zone company instead of mainland, the computation would split. Qualifying income would be taxed at 0%. Non-qualifying income would be taxed at 9%. The de minimis test would apply — if non-qualifying revenue exceeded the lower of AED 5m or 5% of total revenue, the entire entity loses QFZP status for that year and four subsequent years.
The free zone variant of the computation is materially more complex and almost always benefits from advisor review.
Common Errors in First Computations
Three errors recur. First, forgetting to add back depreciation when claiming actual capital allowances — leading to double-counting. Second, applying entertainment limits incorrectly. Third, missing the realisation basis election where unrealised gains have been recognised. Each is small individually; together they can move a tax bill by tens of thousands of dirhams.
Documentation to Keep With the Computation
Keep the computation file together with the final signed financial statements, the trial balance, supporting schedules for each adjustment, the tax computation summary, and a brief sign-off memo. The whole pack should be retained for at least seven years and indexed so a reviewer or FTA auditor can navigate it without explanation.
Frequently Asked Questions
Q1. Is the AED 375,000 threshold per entity or per group?
Per entity, per year. Each separate taxable person has its own AED 375,000 0% band.
Q2. Does an audit need to be completed before I calculate corporate tax?
No, but the tax computation should reconcile back to the final audited or signed-off financials before submission.
Q3. Are dividends from UAE companies taxable?
Dividends from UAE entities are generally exempt under the Participation Exemption, subject to the 5% / 12-month conditions.
Q4. How do I treat losses from prior years?
Tax losses arising under the corporate tax regime can be carried forward indefinitely, subject to ownership-continuity rules and a 75% offset cap.
Q5. Are owner salaries deductible?
Yes, provided they are at arm’s length. Excessive owner salaries can be partially disallowed under the related-party rules.
Q6. Do I have to use IFRS for the calculation?
Most UAE businesses use IFRS or IFRS for SMEs. Other recognised accounting frameworks may be acceptable but should be discussed with an advisor.
