Corporate Tax Computation UAE 2026: How to Calculate Your Tax Liability

0% on the first AED 375,000. 9% on everything above. Sounds simple — but deductions, exempt income, loss carry-forwards, and QFZP rules make the actual computation complex. This guide walks you through the formula step by step, with 3 worked examples (mainland LLC, free zone QFZP, and SBR-eligible business) and every deductible vs non-deductible expense.

UAE Corporate Tax Rates: The Tiered Structure

The UAE corporate tax system under Federal Decree-Law No. 47/2022 uses a simple two-tier rate structure:

Taxable IncomeTax RateWho It Applies To
Up to AED 375,0000%All taxable persons — this is a universal exemption band
Above AED 375,0009%All mainland and non-qualifying free zone income
Large multinationals (revenue > EUR 750M)15%OECD Pillar Two — Domestic Minimum Top-Up Tax (DMTT)
Qualifying Free Zone Person — qualifying income0%QFZP meeting all conditions under Article 18
Small Business Relief (revenue ≤ AED 3M)0% effectiveTaxable income treated as zero. Must elect on return. Until 31 Dec 2026.

The Corporate Tax Computation Formula

The computation starts with your accounting net profit from IFRS-compliant financial statements, then applies a series of adjustments:

UAE Corporate Tax Computation Formula
Accounting Net Profit (per IFRS financial statements)AED XXX
+ Add back: Non-deductible expenses+ AED XXX
− Subtract: Exempt income− AED XXX
− Subtract: Loss carry-forward (up to 75%)− AED XXX
= Taxable IncomeAED XXX
First AED 375,000 × 0%AED 0
Remainder × 9%AED XXX
= Corporate Tax PayableAED XXX

Step 1: Start with Accounting Net Profit (IFRS)

The starting point is your net profit (or loss) from financial statements prepared under International Financial Reporting Standards (IFRS) or equivalent standards accepted by the FTA. This is the bottom line of your income statement after all revenues and expenses.

Businesses with revenue under AED 3 million may use the cash basis of accounting. Above AED 3 million, accrual basis is mandatory.

Step 2: Add Back Non-Deductible Expenses

Certain expenses that reduce your accounting profit are not allowed as deductions for corporate tax purposes. You must add these back:

ExpenseDeductible?Notes
Salaries, wages, employee benefits✅ YesFully deductible if incurred for business purposes
Office rent, utilities✅ YesBusiness premises only
Depreciation, amortisation✅ YesAs per IFRS standards
Professional fees (legal, accounting, audit)✅ YesIf wholly and exclusively for business
Marketing, advertising✅ YesBusiness promotion costs
R&D expenditure✅ YesFully deductible
FTA fines and penalties❌ NoMust add back to profit
Donations to non-qualifying entities❌ NoOnly FTA-approved entities qualify
Entertainment beyond prescribed limits❌ Partially50% cap on entertainment/amusement expenses
Personal expenditure of owners❌ NoOwner withdrawals, personal expenses
Recoverable VAT❌ NoInput VAT you can claim back is not a cost
Interest (connected persons)❌ CappedLimited to 30% of EBITDA for related-party interest
Expenses without documentation❌ NoFTA requires supporting invoices/contracts for all deductions

Step 3: Subtract Exempt Income

Certain types of income are exempt from corporate tax to prevent double taxation:

Domestic dividends — from UAE companies (automatic exemption)

Qualifying participation income — dividends and capital gains from foreign subsidiaries (requires 5%+ ownership held for 12+ months)

Foreign branch income — if the branch is subject to tax at 9%+ in the foreign country (election required)

Intra-group transfers — qualifying transfers between group companies at book value

Step 4: Apply Loss Relief

If your business had a tax loss in a prior period, you can carry it forward to reduce taxable income in future profitable periods. The rules:

• Losses can offset up to 75% of taxable income in any future period

• No time limit on carrying losses forward

• Losses cannot be carried back to prior periods

• The 75% cap ensures some tax is always payable in profitable years

Worked Example 1: Mainland LLC (AED 2M Revenue)

ItemAmount (AED)
Revenue2,000,000
Less: Allowable expenses (salaries, rent, cost of goods)(1,400,000)
Accounting net profit600,000
Add back: Owner’s personal car expense+25,000
Add back: FTA late filing penalty+3,000
Less: Exempt dividend from UAE subsidiary(15,000)
Taxable income613,000
First AED 375,000 × 0%0
Remaining AED 238,000 × 9%21,420
Corporate tax payableAED 21,420

Worked Example 2: Small Business (Under AED 3M — SBR Eligible)

ItemAmount (AED)
Revenue1,200,000
Less: Expenses(900,000)
Accounting net profit300,000
Elect Small Business Relief on returnTaxable income treated as 0
Corporate tax payableAED 0

Worked Example 3: Free Zone Company (QFZP)

ItemAmount (AED)
Total revenue5,000,000
— Qualifying income (sales to other FZ persons + exports)4,700,000
— Non-qualifying income (mainland client services)300,000
De minimis check: 300K / 5M = 6%⚠ Exceeds 5% — QFZP status LOST
All income taxed at 9% above AED 375,000
Taxable income (after expenses of AED 3.5M)1,500,000
First AED 375,000 × 0%0
Remaining AED 1,125,000 × 9%101,250
Corporate tax payableAED 101,250

Warning: If this company’s non-qualifying income had been under 5% (AED 250,000 or less), the qualifying income of AED 4,700,000 would have been taxed at 0% and only the AED 250,000 at 9% — saving AED 91,800 in tax. This is why monitoring the de minimis threshold is critical for free zone companies. Read our QFZP qualifying activities guide →

Interest Deduction Limitation: 30% of EBITDA

For businesses with connected person (related party) borrowings, interest deductions are capped at 30% of EBITDA (Earnings Before Interest, Tax, Depreciation and Amortisation). This prevents excessive debt loading to reduce taxable income.

Excess interest that cannot be deducted in the current period can be carried forward to future periods (subject to the same 30% cap each year).

This rule does not apply to interest on borrowings from unrelated third parties (e.g., bank loans), which remain fully deductible.

Realisation Basis Election

Under IFRS, fair value changes on assets and liabilities flow through profit. For corporate tax purposes, you can elect the realisation basis — meaning unrealised gains/losses are excluded from taxable income until the asset is actually sold or the liability settled.

This election applies to all assets and liabilities subject to fair value or impairment accounting. Once elected, it applies for the entire duration of holding those assets. Full realisation basis guide →

⚠️ The Bottom Line

The formula is straightforward: net profit + add-backs − exemptions − losses = taxable income. But the details — which expenses are deductible, whether you qualify for SBR, how to handle QFZP de minimis — require precision. One wrong deduction can trigger an FTA audit. Professional computation from AED 249 at Fastlane is cheaper than fixing mistakes later.
