How Corporate Tax Changes Your Audit Requirements

1. Expanded Audit Scope

Traditional Statutory Audit Focus:

• Financial statement presentation per IFRS
• Material misstatement detection
• Internal control assessment

New Corporate Tax Audit Requirements:

• Tax reconciliation between accounting profit and taxable profit
• Transfer pricing documentation review
• Permanent vs. temporary difference analysis
• Free zone qualifying income verification (if applicable)
• Related party transaction arm's length assessment
• Tax provision adequacy
• Deferred tax calculation accuracy

Impact: Audit timeline extends by 15-25% to accommodate tax compliance procedures.

2. Accounting Profit vs. Taxable Profit Reconciliation

The profit shown in your IFRS financial statements is NOT your taxable profit. Auditors must now verify the reconciliation:

Example Reconciliation:

Auditor Verification: Your auditor must verify:

• All permanent differences are properly identified and supported
• Temporary differences correctly calculated and will reverse
• Exempt income qualifies for exemption (documentation check)
• Deductions meet Article 28-30 requirements
• Small business relief correctly applied

3. Common Financial Statement Adjustments Required

Based on our experience preparing 850+ Corporate Tax returns in 2024, these adjustments are consistently required:

Adjustment #1: Non-Deductible Entertainment (35% of clients)

IFRS Treatment:

• Booked as operating expense: AED 65,000

Tax Treatment:

• Non-deductible per Article 30(2)
• Add back to taxable income: AED 65,000

Auditor Requirement:

• Obtain breakdown of entertainment expenses
• Assess business purpose (client entertainment vs employee recreation)
• Verify proper classification

Adjustment #2: Depreciation Differences (42% of clients)

IFRS Depreciation:

• Office equipment: 5-year straight-line = AED 80,000/year

Tax Depreciation:

• Tax law allows accelerated depreciation = AED 120,000/year

Impact:

• Temporary difference: AED 40,000 deductible timing difference
• Creates deferred tax asset: AED 40,000 × 9% = AED 3,600

Adjustment #3: Provision for Doubtful Debts (28% of clients)

IFRS Treatment:

• General provision for expected credit losses: AED 95,000

Tax Treatment:

• Only specific write-offs allowed (with evidence)
• Specific identified bad debts: AED 42,000
• General provision not deductible: AED 53,000

Add back: AED 53,000

4. Transfer Pricing Documentation Requirements

Who Needs Transfer Pricing Documentation?

All businesses with related party transactions must prepare:

Related Party Definition:

• Parent, subsidiary, sister companies
• Companies under common control
• Associated entities (25%+ ownership)
• Transactions with owners/shareholders/directors

Required Documentation (per Article 34):

Tier 1: Local File (All related party transactions)

• Description of business and industry
• Organizational structure
• Related party transaction details
• Functional analysis (functions, assets, risks)
• Economic analysis demonstrating arm's length pricing
• Deadline: Available when tax return filed

Tier 2: Master File (Only if group revenue exceeds AED 3.15 billion)

• Global group structure
• Description of group business
• Group intangibles
• Group financing activities
• Financial and tax positions
• Deadline: Within 12 months of financial year-end

Tier 3: Country-by-Country Report (Only if group revenue exceeds €750 million)

• Revenue, profit, taxes paid by jurisdiction
• Employees and tangible assets by jurisdiction
• Deadline: Within 12 months of financial year-end

Case Study: Manufacturing Company Transfer Pricing Audit

Company Profile:

• UAE manufacturing subsidiary of German parent
• Revenue: AED 450M
• Purchases raw materials from parent: AED 180M annually
• Pays management fees to parent: AED 15M annually
• Licenses technology from parent: AED 8M royalties annually

FTA Corporate Tax Audit Findings:

Issue #1: Management Fees

• FTA challenged: "What specific services justify AED 15M fee?"
• Company provided only generic description
• FTA benchmarking: Similar services should cost 3-5% of revenue (AED 13.5M-22.5M)
• Result: Accepted as reasonable after company provided detailed service logs

Issue #2: Royalty Rates

• Royalty rate: 1.8% of revenue
• FTA benchmark: Industry standard 1.2-2.5%
• Result: Within acceptable range, no adjustment

Issue #3: Raw Material Pricing

• Parent charged AED 180M (cost + 12% markup)
• FTA requested comparable uncontrolled price analysis
• Independent supplier quotes: Cost + 8-10% typical
• Proposed adjustment: Disallow AED 3.6M excess markup
• Outcome: Company provided functional analysis showing parent provides technical support, quality assurance, and R&D - justifying higher markup
• Final result: FTA accepted 10% markup, disallowed AED 1.8M (2% excess)

Tax Impact:

• Disallowed expense: AED 1.8M
• Additional taxable income: AED 1.8M - AED 375K exempt = AED 1.425M
• Additional tax: AED 128,250 (9%)
• Penalty: AED 25,650 (20% - insufficient documentation)
• Total cost: AED 153,900

Key Lessons:

1. Prepare transfer pricing documentation BEFORE transactions, not after audit
2. Benchmark all related party pricing against market comparables
3. Document economic substance for premium pricing

5. Free Zone Entity Special Rules

Free zone companies can qualify for 0% Corporate Tax on qualifying income, but must meet stringent requirements.

Qualifying Free Zone Person Criteria:

To benefit from 0% tax, ALL conditions must be met:

• Maintains adequate substance in UAE free zone
• Earns only qualifying income
• Complies with all regulatory requirements
• Has not elected to be subject to 9% corporate tax
• Meets transfer pricing requirements

Qualifying Income (0% tax) vs. Non-Qualifying Income (9% tax):

Scroll to see all columns →

Critical Audit Requirement:

Auditors must verify proper segregation and tracking of qualifying vs. non-qualifying income:

Example:

• Total revenue: AED 10M
• Sales to other FZ companies: AED 6M (qualifying)
• Sales to UAE mainland companies: AED 3M (non-qualifying)
• Rental income from mainland property: AED 1M (non-qualifying)

Tax Calculation:

• Qualifying income: AED 6M × 0% = AED 0
• Non-qualifying income: AED 4M
• Allocable expenses: AED 2.5M (must be apportioned)
• Non-qualifying taxable income: AED 1.5M
• Tax: (AED 1.5M - AED 375K) × 9% = AED 101,250

Common Audit Finding: Failure to properly track and separate income streams, resulting in loss of free zone benefits.

Common Corporate Tax Audit Findings and Prevention

Based on our 850+ Corporate Tax returns prepared and 67 FTA audits supported in 2024:

Finding #1: Inadequate Transfer Pricing Documentation (41% of audits)

The Issue: Related party transactions without proper arm's length evidence.

What FTA Challenges:

• Management fees without clear service descriptions
• Intercompany loans without interest benchmarking
• Royalties without justification
• Buy/sell pricing without comparable analysis

Prevention:

• Prepare contemporaneous transfer pricing documentation
• Obtain independent benchmarking studies
• Document economic substance for each transaction
• Annual review of pricing policies

Finding #2: Incorrect Free Zone Income Classification (33% of audits)

The Issue: Treating non-qualifying income as qualifying (claiming 0% instead of 9%).

Common Mistakes:

• Sales to UAE mainland companies claimed as qualifying
• Rental income from mainland property
• Interest from mainland banks
• IP licensing where substance lacking

Prevention:

• Implement income tracking by customer location
• Monthly review of income classification
• Quarterly substance assessment
• System flags for mainland transactions

Finding #3: Non-Deductible Expenses Claimed (29% of audits)

Commonly Disallowed Expenses:

• Entertainment and recreation
• Fines and penalties
• Political contributions
• Non-arm's length related party charges
• Personal expenses of owners/shareholders
• Depreciation on non-business assets

Prevention:

• Pre-approval process for questionable expenses with tax review
• Expense classification codes aligned with tax rules
• Quarterly review of deductibility

Finding #4: Small Business Relief Misapplication (18% of audits)

The Issue: Incorrectly calculating or claiming AED 375,000 exemption.

Common Errors:

• Claiming relief when revenue exceeds AED 3M threshold (small business relief has revenue eligibility cap for certain scenarios)
• Group companies each claiming relief (should be one claim per group)
• Double-counting relief in mid-year tax period changes

Prevention:

• Verify small business relief eligibility criteria
• Coordinate group relief claims
• Document relief calculation methodology

Frequently Asked Questions

Q: Do I need both a statutory audit and a separate tax audit? A: No separate "tax audit" is required. Your statutory auditor will incorporate Corporate Tax verification procedures into the annual audit. However, complex tax positions may require separate tax advisory services.

Q: Can I deduct losses from prior years (before June 1, 2023)? A: No. Tax losses can only be carried forward from periods after June 1, 2023. Prior losses under no-tax regime cannot be utilized.

Q: What if my accounting profit is negative (loss)? A: You have zero taxable income (no tax due) and can carry the tax loss forward indefinitely to offset future taxable profits. Losses cannot be carried back.

Q: Are dividends received from UAE subsidiaries taxable? A: Generally exempt if you meet participation exemption conditions (5%+ ownership, 12+ month holding). Auditor must verify qualification for exemption.

Q: How do I know if my transfer pricing is "arm's length"? A: Compare your pricing to comparable uncontrolled transactions (independent third parties). Engage transfer pricing specialist for benchmarking study.

Q: What is the penalty for incorrect tax return? A:

• Unintentional error: 10% of unpaid tax
• Intentional error: 50% of unpaid tax
• Tax evasion/fraud: 100% of unpaid tax + potential criminal prosecution
