Understanding Interest Deductibility Under UAE Corporate Tax Law
The introduction of Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses marked a significant shift in how UAE companies approach financing costs. For businesses with debt-heavy capital structures—whether private equity-backed entities, real estate developers, or multinational subsidiaries—the interest deductibility rules UAE framework demands careful attention to EBITDA calculations, threshold monitoring, and documentation requirements.
Unlike the previous tax-free environment, the UAE now operates a system where net interest expense exceeding specified limits becomes non-deductible, creating permanent tax differences that directly impact cash flow and investment returns. This article breaks down the mechanics of these rules, the safe harbors available, and practical strategies for structuring financing arrangements in compliance with UAE requirements.
The 30% EBITDA Limitation Rule
Article 29 of the Corporate Tax Law establishes the primary limitation on interest deductibility. Under this provision, a taxpayer's net interest expenditure is deductible only up to 30% of their adjusted EBITDA for the relevant tax period.
Calculating Adjusted EBITDA for UAE Tax Purposes
The EBITDA calculation under UAE law requires specific adjustments to accounting profit:
- Start with accounting profit before corporate tax deduction
- Add back: Net interest expenditure, depreciation and amortization, and corporate tax calculated on taxable income
- Add back: Other non-deductible expenditures (fines, penalties, donations exceeding limits)
- Subtract: Exempt income and qualifying group relief items
This adjusted figure becomes the denominator for the 30% limitation calculation. Notably, the UAE methodology aligns broadly with OECD BEPS Action 4 recommendations while incorporating local modifications.
Practical Calculation Example
Consider a Dubai-based holding company with the following profile:
- Accounting profit: AED 15 million
- Interest expense: AED 8 million
- Interest income: AED 1 million
- Depreciation and amortization: AED 3 million
- Non-deductible penalties: AED 500,000
Adjusted EBITDA = 15 + 7 (net interest) + 3 + 0.5 = AED 25.5 million
Interest deduction limit = 30% × 25.5 = AED 7.65 million
In this scenario, AED 350,000 of net interest expense becomes non-deductible, creating a permanent addition to taxable income.
Safe Harbor Thresholds and De Minimis Exemptions
The interest deductibility rules UAE framework includes important relief mechanisms for smaller taxpayers and specific financing arrangements.
The AED 12 Million Safe Harbor
Taxpayers whose net interest expenditure does not exceed AED 12 million in a tax period are entirely exempt from the 30% EBITDA limitation. This threshold is assessed before application of the limitation rule—meaning businesses below this level face no restriction regardless of their EBITDA position.
This safe harbor particularly benefits:
- SMEs with moderate leverage
- Family-owned businesses with external bank financing
- Professional service firms with equipment financing
- Trading companies with working capital facilities
Specific Excluded Interest Categories
Certain interest types fall outside the limitation framework entirely:
- Interest on existing loans—debt incurred before 9 December 2022 (grandfathering provisions apply with conditions)
- Interest on loans from UAE banks or financial institutions—when not part of structured arrangements
- Interest on loans from related parties—subject to separate transfer pricing and beneficial ownership tests
These exclusions require careful documentation to substantiate eligibility, particularly for grandfathered debt where loan agreements and drawdown dates must be clearly evidenced.
Financing Structuring Strategies for UAE Businesses
Proactive structuring can optimize interest deductibility within the interest deductibility rules UAE compliance framework.
Equity vs. Debt Optimization
Businesses approaching the 30% threshold should evaluate hybrid financing instruments. Consider:
- Profit-participating instruments that may qualify as equity for tax purposes while providing fixed-return characteristics
- Convertible instruments with carefully structured conversion features
- Shareholder loan restructuring to equity where interest capacity is constrained
Group Financing Arrangements
UAE groups can leverage specific provisions to optimize interest deductibility across the consolidated position:
- Group relief for interest—transferring excess interest capacity from high-EBITDA to low-EBITDA group entities
- Centralized treasury functions—with appropriate substance and transfer pricing documentation
- Cross-border financing platforms—utilizing UAE's extensive treaty network while managing limitation risks
EBITDA Enhancement Techniques
Legitimate EBITDA improvement strategies include:
- Accelerating revenue recognition where accounting standards permit
- Deferring discretionary non-deductible expenditures
- Structuring asset acquisitions to maximize depreciation add-backs
- Reviewing related-party transactions for arm's length pricing adjustments
Transfer Pricing and Related-Party Considerations
Interest on related-party debt faces dual scrutiny under both the limitation rules and transfer pricing regulations. The UAE Federal Tax Authority applies specific tests:
- Beneficial ownership requirement—the lender must be subject to tax on the interest income at a rate not less than 9%
- Arm's length interest rate—benchmarked against comparable uncontrolled transactions
- Thin capitalization—implicit in the EBITDA limitation but supplemented by substance requirements
Related-party interest failing these tests faces disallowance independent of the 30% limitation, creating a double compliance burden that requires integrated documentation.
Documentation and Compliance Requirements
Maintaining robust records is essential for interest deductibility rules UAE UAE compliance. Required documentation includes:
- Detailed EBITDA reconciliation working papers
- Loan agreements with clear interest rate terms
- Transfer pricing documentation for related-party financing
- Evidence of beneficial ownership for cross-border interest payments
- Grandfathering documentation for pre-December 2022 debt
The Federal Tax Authority has indicated that interest limitation calculations will be a focus area in tax audits, particularly for private equity portfolio companies and real estate investment structures.
Industry-Specific Applications
Real Estate and Construction
Development projects with extended construction periods face unique challenges. Interest during development may be capitalized for accounting purposes but requires careful tracking for tax EBITDA calculations. Forward-looking developers are modeling interest capacity through operational phases to avoid trapped tax losses.
Private Equity Portfolio Companies
Leveraged buyout structures must integrate UAE limitations with global interest restriction regimes. The UAE's 30% EBITDA approach may be more or less restrictive than other jurisdictions, requiring dynamic capital structure management.
Multinational Treasury Centers
Dubai International Financial Centre and Abu Dhabi Global Market entities operating as regional treasury centers must demonstrate adequate substance and arm's length remuneration to support interest deductions on inbound financing arrangements.
Actionable Next Steps for UAE Businesses
To ensure interest deductibility rules UAE compliance and optimize your tax position:
- Conduct an interest capacity assessment—model your current and projected EBITDA against net interest expense for the next 3-5 tax periods
- Review financing documentation—verify grandfathering eligibility and beneficial ownership chains
- Benchmark related-party interest rates—update transfer pricing documentation to current market conditions
- Evaluate restructuring opportunities—consider equity injections, hybrid instruments, or group relief mechanisms before tax periods close
- Establish monitoring protocols—implement quarterly EBITDA and interest tracking to enable proactive management
Given the complexity of multi-jurisdictional financing and the interaction between UAE rules and other limitation regimes, professional guidance is strongly recommended for leveraged structures.

Frequently Asked Questions
How do UAE interest deductibility rules apply to Islamic finance structures?
Islamic finance instruments such as murabaha, ijara, and sukuk are generally treated as debt equivalents for UAE corporate tax purposes. The profit or rental components that economically substitute for interest are subject to the same 30% EBITDA limitation. However, specific structuring—particularly around commodity murabaha arrangements—may affect the timing and characterization of deductible amounts. Businesses using Sharia-compliant financing should obtain specific rulings on their structures.
Can carried-forward interest disallowed under the 30% limit be deducted in future periods?
No. Unlike some jurisdictions that permit indefinite carryforward of excess interest, the UAE regime creates a permanent disallowance. Interest expense exceeding the 30% EBITDA limit in a tax period is lost permanently and cannot be recovered in subsequent periods when EBITDA may be higher. This asymmetric treatment makes accurate annual forecasting critical for tax-efficient financing management.
How are foreign exchange gains and losses treated in the net interest calculation?
Foreign exchange differences on interest-bearing liabilities are generally excluded from the net interest expenditure calculation unless they are economically equivalent to interest. The Federal Tax Authority has indicated that exchange differences reflecting the time value of money—such as on long-dated foreign currency loans—may be recharacterized as interest for limitation purposes. Businesses with significant foreign currency debt should analyze their specific arrangements and consider hedging strategies that clarify the character of foreign exchange outcomes.
Do the interest limitation rules apply differently to free zone entities?
Free zone entities qualifying for the 0% corporate tax rate on qualifying income are technically subject to the same interest limitation rules, but the practical impact differs. For qualifying income, the limitation affects only the calculation of taxable income that would otherwise be subject to 0% tax. However, non-qualifying income—such as domestic UAE mainland income—faces full application of the 30% EBITDA limit. Free zone entities with mixed income streams must maintain careful allocation of interest expense between qualifying and non-qualifying activities.
How do the UAE rules interact with the OECD Pillar Two global minimum tax?
The interaction between domestic interest limitations and Pillar Two's GloBE rules creates complex planning considerations. Under Pillar Two, excessive interest deductions that reduce effective tax rates below 15% may trigger top-up tax in other jurisdictions. UAE businesses with international operations should model both the domestic 30% EBITDA limitation and the global anti-base erosion provisions to identify optimal financing structures that minimize total tax liability across all applicable regimes.
What documentation is required to support the AED 12 million safe harbor election?
While the safe harbor applies automatically when net interest expenditure is below the threshold, taxpayers should maintain contemporaneous documentation including: detailed schedules of all interest-bearing arrangements, reconciliation of accounting interest to tax-deductible interest, and evidence that no artificial fragmentation of borrowing has occurred. The Federal Tax Authority may scrutinize arrangements where related-party financing is structured to keep multiple entities below the threshold.
Can EBITDA adjustments include anticipated future income from long-term contracts?
No. The UAE Corporate Tax Law requires EBITDA to be calculated based on actual income and expenditures recognized in the tax period. Anticipated or accrued income not meeting revenue recognition criteria under applicable accounting standards cannot be included. This creates particular challenges for project-based businesses with lumpy revenue recognition, who may need to consider milestone-based financing drawdowns to align interest expense with recognized EBITDA.
How are guarantee fees and commitment fees treated under the interest limitation rules?
Fees economically equivalent to interest—including standby commitment fees, guarantee fees paid to related parties, and arrangement fees that represent compensation for the time value of money—are generally included in net interest expenditure. Fees for pure administrative services or one-time arrangement services may be excluded if properly characterized and documented. The substance of the arrangement rather than its label determines treatment, requiring careful analysis of fee structures in credit facilities.
Do the interest deductibility rules apply to UAE branches of foreign companies?
UAE branches of foreign companies are subject to the full interest limitation framework. For branches with financing provided by head office or other group entities, the beneficial ownership test and arm's length pricing requirements apply with particular stringency. Branches should ensure that interest allocations from head office are supported by clear funding arrangements and that the foreign head office is subject to adequate taxation on the corresponding interest income.
What penalties apply for incorrect interest limitation calculations?
Understating taxable income through incorrect interest deductions attracts standard corporate tax penalties, including: 2% monthly late payment interest on underpaid tax, fixed penalties for incorrect returns, and potential penalties of up to 300% for tax evasion in severe cases. Given the complexity of EBITDA adjustments and the permanent nature of interest disallowance errors, businesses should consider voluntary disclosures where errors are discovered, as the UAE framework provides for penalty reductions for proactive compliance corrections.
