If your taxable profit in the UAE crosses AED 375,000, you’ll likely owe corporate tax, usually 9% on the slice above that line. The trick is calculating taxable income correctly, so you don’t overpay (or miss a relief you qualify for).
Start from Accounting Profit, then Adjust
Begin with your audited profit and convert it to taxable income by adding back non-deductibles (e.g., some fines), applying depreciation per the CT Law, and limiting interest per the FTA’s Interest Deduction Limitation guide. Think “accounting profit → tax adjustments → taxable income.”
Example: If your financial statements show AED 1,000,000 profit, and you add back AED 40,000 of non-deductible expenses, taxable income becomes AED 1,040,000 (before loss offsets or reliefs).

Apply the UAE Rate Bands Correctly
For most mainland businesses, the 2025 rate is:
0% on the first AED 375,000 of taxable income
9% on the remainder
This applies to financial years that began on or after June 1, 2023 and continue in 2025.
Quick math: With taxable income of AED 1,040,000:
0% on AED 375,000 = AED 0
9% on AED 665,000 = AED 59,850 payable
Large multinationals may face a 15% top-up under OECD rules from 2025, outside the scope of most SMEs, but worth noting for groups above EUR 750m revenue.
Check Small Business Relief (SBR) Before you Compute
If your revenue is ≤ AED 3 million (for each relevant tax period and all prior periods) and you meet the residency conditions, you can elect SBR so that no corporate tax applies for that period. SBR is available through 31 December 2026 (subject to conditions and elections each year)
Electing SBR can limit loss carryforwards and certain deductions for that period, so weigh cash savings vs. future planning. A corporate tax consultant in Dubai can model both paths.
Use Losses Wisely
Tax losses from post-CT periods can typically offset up to 75% of future taxable income (subject to conditions). That means you’ll still pay 9% on at least 25% of that year’s taxable income after the offset. Losses can generally be carried forward (conditions apply).
Example: Taxable income AED 1,000,000 with AED 600,000 carried losses: you can offset up to AED 750,000; tax applies to the remaining AED 250,000 (9% on AED 250,000).
Free Zone? Verify Qualifying Free Zone Person status
Free zone companies can enjoy 0% on qualifying income if they meet annual tests (substance, audited accounts, qualifying activities, and de minimis on non-qualifying income). Fall short, and the 9% rate applies like the mainland. Don’t assume; check the FTA Free Zone guide, and keep evidence.
If you bill both qualifying and non-qualifying income, track them cleanly. A corporate tax consultant can help preserve QFZP status with proper documentation each year.
Step 6: File on Time, Your First Real Deadline Might Be 2025
Returns and payment are due within nine months from the financial year-end (e.g., 31 Dec 2025 year-end → 30 Sep 2026 due date). Late filing risks penalties; put a tax calendar next to your VAT services in Dubai deadlines so finance teams don’t miss anything.

FAQs in one minute
How is “profit” different from “taxable income”?
Taxable income is adjusted accounting profit after CT-specific rules (e.g., interest cap).
Are all SMEs taxed at 9%?
No. SMEs under the AED 3m revenue threshold can elect SBR through 2026 if conditions are met.
Do free zones automatically get 0%?
No. You must meet QFZP tests every year and file returns regardless.
