Navigating Corporate Tax Rules on Interest Capping: A Strategic Guide
The UAE Corporate Tax Law is a sophisticated piece of legislation, drawing heavily from international best practices designed to create a fair and transparent tax system. One of the most significant and technically complex of these principles is the “interest capping rule,” also known as the General Interest Limitation Rule. For businesses that rely on debt financing—whether for capital investments, operational funding, or expansion—understanding this rule is not just a matter of compliance; it’s a critical component of financial strategy. The rule is specifically designed to combat base erosion and profit shifting (BEPS) by preventing companies from using excessive interest deductions to artificially reduce their taxable profits in the UAE.

This introduces a new paradigm for financial planning. How much debt is too much? How will inter-company loans be treated? What is “tax EBITDA,” and how is it different from the EBITDA on my management reports? Failure to address these questions can lead to unexpected tax liabilities, reduced cash flow, and challenges to your capital structure. This guide provides a comprehensive walkthrough of the UAE’s interest capping rules, explaining the core mechanics, the calculation methodologies, and the strategic implications for your business. It is an essential read for CFOs, finance directors, and business owners who need to navigate the intricate relationship between their financing decisions and their corporate tax obligations.
Key Takeaways on Interest Capping Rules
- Purpose: The rule limits the amount of net interest expense a business can deduct to combat tax avoidance through excessive debt.
- The Main Limit: Your deductible Net Interest Expense is capped at 30% of your tax-adjusted EBITDA.
- The Safe Harbour (De Minimis): If your Net Interest Expense for the year is AED 12 million or less, the 30% rule does not apply, and the full amount is deductible.
- “Tax EBITDA” is Key: This is not your accounting EBITDA. It’s calculated by taking Taxable Income and adding back net interest, tax depreciation, and tax amortization.
- Disallowed Interest is Not Lost: Any interest expense disallowed under the cap can be carried forward and potentially deducted in the next 10 tax periods.
- Certain Entities are Exempt: Banks, insurance providers, and Qualifying Public Benefit Entities are generally exempt from these rules.
Part 1: The Rationale Behind Interest Capping
The General Interest Limitation Rule, outlined in Article 30 of the Corporate Tax Law, is the UAE’s implementation of the recommendations from the OECD’s BEPS project, specifically Action 4. The primary goal is to prevent companies from:
- Excessive Debt: Placing a high level of third-party debt in a high-tax country to maximize interest deductions.
- Profit Shifting: Using internal, related-party loans with high interest rates to move profits from the UAE to a low or no-tax jurisdiction.
By limiting the deductibility of interest, the law ensures that a company’s taxable profit is aligned with its actual economic activity and substance in the UAE. It encourages businesses to maintain a prudent and commercially sensible balance between debt and equity in their capital structure.
Part 2: The Core Mechanics – The Calculation Framework
For any given tax period, a business must determine its maximum deductible net interest expense. This is done by applying a two-step test.
Step 1: The De Minimis Threshold
This is a crucial “safe harbour” designed to exclude the vast majority of small and medium-sized enterprises from the complexity of the main rule.
The Rule: If your Net Interest Expense for the tax period is AED 12,000,000 or less, you can deduct the full amount. You do not need to proceed to Step 2.
“Net Interest Expense” is defined as your total interest expense minus your total interest income. If your interest income exceeds your interest expense, your Net Interest Expense is zero, and the rule does not apply.
Step 2: The 30% of EBITDA Cap
If your Net Interest Expense exceeds AED 12 million, your maximum deductible amount is the higher of:
- The De Minimis Threshold (AED 12 million).
- 30% of your tax-adjusted EBITDA.
Calculating “Tax EBITDA”
This is the most critical and often misunderstood part of the calculation. This is not the EBITDA you see in your management accounts. It is a specific calculation for tax purposes only.
Tax EBITDA = Taxable Income + Net Interest Expense + Tax Depreciation + Tax Amortization
- Taxable Income: This is your accounting profit *after* it has been adjusted for all other Corporate Tax rules (e.g., non-deductible expenses, transfer pricing adjustments), but *before* deducting net interest expense.
- Net Interest Expense: The same figure calculated in Step 1.
- Tax Depreciation & Amortization: The depreciation and amortization allowed for Corporate Tax purposes, which may differ from the amounts in your accounting records.
Example Calculation
Let’s consider a company, “UAE Trading LLC,” for the year 2024.
| Financial Item | Amount (AED) | Notes |
|---|---|---|
| Accounting Profit before interest & tax | 150,000,000 | This is the starting point. |
| Interest Expense (on bank loans) | 25,000,000 | |
| Interest Income (from deposits) | (2,000,000) | |
| Net Interest Expense | 23,000,000 | Exceeds the AED 12m threshold, so the 30% cap applies. |
| Accounting Depreciation | 10,000,000 | |
| Tax Depreciation (allowed by CT Law) | 8,000,000 | The tax-adjusted figure must be used. |
| Non-Deductible Expenses (e.g., fines) | 1,000,000 | An example of a tax adjustment. |
Now, let’s calculate the maximum deductible interest:
- Calculate Taxable Income (before interest deduction):
Accounting Profit (150m) + Non-Deductible Expenses (1m) = AED 151,000,000 - Calculate Tax EBITDA:
Taxable Income (151m) + Net Interest Expense (23m) + Tax Depreciation (8m) = AED 182,000,000 - Calculate the 30% Cap:
30% of AED 182,000,000 = AED 54,600,000 - Determine the Limit:
The maximum deductible amount is the higher of the 30% cap (54.6m) and the de minimis threshold (12m). So, the limit is AED 54,600,000. - Final Result:
The company’s Net Interest Expense is AED 23,000,000, which is less than the limit of AED 54,600,000. Therefore, the full AED 23,000,000 is deductible.
Part 3: Carry Forward of Disallowed Interest
What if, in the example above, the 30% cap was lower than the actual net interest expense? The disallowed portion is not permanently lost.
The Rule: Any Net Interest Expense that is disallowed in a tax period because of the cap can be carried forward and treated as an interest expense incurred in the subsequent 10 tax periods.
In each subsequent year, the carried-forward interest is added to that year’s current interest expense and is deductible up to that year’s interest capping limit. The oldest carried-forward amounts must be used first.
Part 4: The Importance of Accurate Financial Data
As the calculation demonstrates, the interest capping rule relies on precise, well-documented financial data. Every component—interest income, interest expense, tax depreciation, and various tax adjustments—must be accurately tracked. This is where a robust accounting system becomes a non-negotiable compliance tool.
A system like Zoho Books provides the necessary infrastructure. Its detailed chart of accounts allows you to segregate different types of interest. Its fixed asset module can track both accounting and tax depreciation schedules. Most importantly, it provides a clean, auditable data source, forming the bedrock of your tax calculations and ensuring you can defend your position to the FTA.

Frequently Asked Questions (FAQs) on Interest Capping
The definition is broad. It includes not just standard interest on loans, but also amounts that are economically equivalent to interest. This can cover things like guarantee fees, arrangement fees, Islamic financing profit returns, and foreign exchange gains/losses on the principal of a loan.
They are two separate tests that must both be passed. First, the interest rate on a related-party loan must be at an arm’s length rate, as determined by transfer pricing rules. Any interest paid above this rate is disallowed. Then, the remaining, arm’s length interest amount is added to your other interest expenses and becomes subject to the 30% EBITDA capping rule.
If your tax EBITDA is zero or negative, your 30% cap will also be zero. In this case, your maximum deductible net interest expense would be the de minimis threshold of AED 12 million. Any interest expense above this amount would be disallowed and carried forward.
The threshold and the 30% EBITDA calculation apply at the level of the Taxable Person. This means it applies to a standalone company or, if you have formed one, to the Tax Group as a whole on a consolidated basis.
Yes, the law includes a specific exclusion for interest incurred on debt instruments issued to finance a “Qualifying Long-Term Infrastructure Project.” This is a complex area with specific conditions, designed to ensure that major public infrastructure development is not hindered by the rule.
The rules around the survival of tax attributes like carried-forward interest after a change in ownership are complex. Generally, if the same business is continued after the acquisition, the attribute may be carried over. However, this requires careful analysis and is a key part of tax due diligence.
Yes. A QFZP is a Taxable Person and is subject to all the general rules of the Corporate Tax Law unless a specific exemption applies. The interest capping rules apply to QFZPs. However, since a QFZP’s 0% tax rate only applies to its “Qualifying Income,” the practical impact may differ depending on how its income is structured.
Absolutely. Interest on shareholder loans is treated the same as interest on a bank loan. It must first meet the arm’s length test under transfer pricing rules, and then it is included in the total net interest expense that is subject to the capping rule.
No. If your net interest expense is zero or negative, the rule simply doesn’t apply. You are taxed on your net interest income as part of your regular taxable income. You cannot use any “excess capacity” to increase the deduction of other expenses.
You must use the tax depreciation figure. The entire calculation is based on tax-adjusted numbers, not your standard accounting figures. This is a critical distinction and a common source of error, making robust account reconciliation between book and tax figures essential.
Conclusion: Integrating Tax into Financial Strategy
The UAE’s interest capping rule is more than just a compliance hurdle; it is a strategic driver that forces a closer alignment between a company’s financial strategy and its tax planning. It elevates the conversation around capital structure from a purely financial decision to one with direct tax consequences. Businesses that proactively model the impact of these rules, maintain immaculate financial records, and structure their financing with a clear understanding of the limitations will be best positioned to manage their tax liabilities effectively. For CFOs and finance leaders, this rule underscores the new reality in the UAE: tax is no longer a year-end calculation but a continuous, strategic consideration that must be embedded in every major financial decision.
