UAE Interest Capping Rules: How Much Interest Expense Can You Deduct?
The introduction of UAE Corporate Tax brought with it a host of new regulations that businesses must navigate. Among the most significant and complex of these are the **Interest Capping Rules**. Designed to prevent companies from eroding their taxable income through excessive debt financing (a practice known as base erosion and profit shifting, or BEPS), these rules place a specific limit on the amount of net interest expense a business can deduct in a tax period.

For businesses that rely on debt—whether from banks or related companies—to finance their operations, expansion, or acquisitions, these rules are not just a compliance footnote; they can have a direct and substantial impact on the final tax bill. Understanding the calculation, the thresholds, and the exemptions is crucial for effective tax planning and financial management.
This guide provides a detailed breakdown of the UAE’s Interest Capping Rules. We will explain the general and specific rules, define the key terms like “EBITDA” in the context of the tax law, and walk through a practical example. As expert UAE Corporate Tax consultants, we will also explore the strategic implications and how professional guidance can help you optimize your position while remaining fully compliant.
Key Takeaways
- The Core Rule: The amount of net interest expense you can deduct is capped at 30% of your tax-adjusted EBITDA (Earnings Before Interest, Tax, Depreciation, and Amortization).
- What is Net Interest Expense?: It is your total interest expense minus your total interest income for the period.
- De Minimis Threshold: The rule does not apply if your net interest expense for the relevant tax period is AED 12 million or less. This exempts many SMEs.
- Disallowed Interest Can Be Carried Forward: Any interest expense that is disallowed due to the cap is not lost forever. It can be carried forward and potentially deducted in the next 10 tax periods.
- Certain Businesses are Exempt: The rules do not apply to banks, insurance providers, and certain other regulated financial entities.
- Strategic Importance: These rules require businesses to carefully consider their capital structure (debt vs. equity) and inter-company financing arrangements.
The Two Layers of Interest Deduction Rules
To understand the capping rule, you must first understand that there are two hurdles an interest expense must clear to be deductible.
1. The General Interest Deduction Rule
Before the capping rule even comes into play, any interest expense must first meet the general deductibility criteria under the Corporate Tax Law. This means the expense must be incurred **wholly and exclusively** for the purposes of the taxpayer’s business. Interest on a loan taken to fund a business acquisition would generally meet this criterion. Interest on a loan taken by the owner for a personal expense and routed through the company would not.
2. The Specific Interest Capping Rule
If an interest expense passes the “wholly and exclusively” test, it then becomes subject to the specific capping rule. This rule limits the *amount* of net interest expense that can be deducted.
The maximum deductible net interest expense is the **higher** of:
- AED 12,000,000 (the de minimis threshold).
- 30% of the business’s tax-adjusted EBITDA for the relevant tax period.
In simple terms: if your net interest expense for the year is AED 12 million or less, you don’t need to worry about the 30% EBITDA calculation; you can deduct the full amount (provided it meets the general rule). If your net interest expense exceeds AED 12 million, you must perform the calculation.
Defining “EBITDA” for the Interest Capping Rule
It’s crucial to understand that the EBITDA used for this calculation is not the same as the accounting EBITDA you might see on a standard financial report. It is a specific, tax-adjusted figure calculated as follows:
Taxable Income
(+) Add back: Net Interest Expense for the period
(+) Add back: Depreciation Expense for the period
(+) Add back: Amortization Expense for the period
= Tax-Adjusted EBITDA
This calculation starts with your taxable income *before* any net interest deduction, and then adds back the non-cash expenses of depreciation and amortization. This creates a proxy for the company’s operating cash flow before financing costs, which is then used as the base for the 30% cap.
A Practical Example of the Calculation
Let’s see how this works in practice for a company with significant debt.
| Financial Item | Amount (AED) | Notes |
|---|---|---|
| Taxable Income (before interest) | 100,000,000 | This is the company’s profit before considering interest. |
| Total Interest Expense | 25,000,000 | From various loans. |
| Total Interest Income | (5,000,000) | From deposits or loans to other entities. |
| Net Interest Expense | 20,000,000 | (25M – 5M). This is above the 12M threshold, so the cap applies. |
| Depreciation & Amortization | 10,000,000 | Non-cash expenses for the period. |
Step 1: Calculate Tax-Adjusted EBITDA
- Taxable Income (before interest): AED 100,000,000
- Add: Net Interest Expense: AED 20,000,000
- Add: Depreciation & Amortization: AED 10,000,000
- Tax-Adjusted EBITDA = AED 130,000,000
Step 2: Calculate the Interest Deduction Limit
- 30% of Tax-Adjusted EBITDA = 30% * 130,000,000 = AED 39,000,000
Step 3: Determine the Deductible Amount
- The company’s actual Net Interest Expense is AED 20,000,000.
- The calculated limit is AED 39,000,000.
- Since the actual expense (20M) is less than the limit (39M), the company can deduct the **full AED 20,000,000** of its net interest expense.
Now, let’s change one number. What if the company’s Taxable Income was only AED 50,000,000?
New EBITDA: 50M (Taxable Income) + 20M (Net Interest) + 10M (D&A) = AED 80,000,000
New Limit: 30% of 80M = AED 24,000,000
In this case, the result is the same. The company can still deduct the full 20M.
But what if the company’s Net Interest Expense was much higher, say AED 40,000,000?
Actual Net Interest Expense: AED 40,000,000
Limit (from first example): AED 39,000,000
Deductible Amount: The company can only deduct **AED 39,000,000**.
Disallowed Amount: AED 1,000,000 (40M – 39M). This amount can be carried forward for up to 10 years.

Frequently Asked Questions (FAQs)
Yes. The interest capping rules apply to all interest expenses, whether paid to third parties (like banks) or related parties. In fact, loans from related parties are often scrutinized more heavily to ensure they are on arm’s length terms.
If, after 10 subsequent tax periods, you have not been able to deduct the carried-forward interest amount (because your net interest expense consistently exceeds your 30% EBITDA limit), the unused amount expires and is permanently lost as a tax deduction.
It applies to your **net interest expense**. You must first calculate your total interest expense for the period and subtract your total interest income. If that net figure is AED 12 million or less, the capping rule does not apply to you for that period.
If you have formed a Tax Group for UAE Corporate Tax purposes, the interest capping rules are applied at the level of the Tax Group. The net interest expense and tax-adjusted EBITDA of all members of the group are consolidated to perform a single calculation.
Yes. The definition of “interest” under the law is broad and includes amounts that are economically equivalent to interest, such as the profit element on Islamic financing instruments like Murabaha or Ijarah.
If your business has a taxable loss, your taxable income would be a negative number. You would still follow the formula: start with the negative taxable income, then add back your net interest, depreciation, and amortization. It’s possible to have a positive tax-adjusted EBITDA even if you have a bottom-line tax loss.
Yes. The law provides an exemption for businesses engaged in long-term public infrastructure projects, recognizing that these ventures are typically highly leveraged over long periods. Specific conditions must be met to qualify for this exemption.
No. These rules are designed to limit the *deduction of interest expense*. If you only have interest income and no interest expense, you have a negative net interest expense, and the rules will not apply to you. Your interest income will simply be part of your taxable income.
No. The calculation for a given year is always based on that year’s net interest expense. The carried-forward amount is treated separately. In any given year, you can deduct up to your 30% EBITDA limit. If your current year’s interest is below this limit, you can then use any remaining capacity to deduct the interest carried forward from previous years.
Strategic management involves several levers. You could look at refinancing debt at lower interest rates, re-evaluating your capital structure to use more equity financing instead of debt, or timing major capital expenditures (which create depreciation) to align with periods of high interest. For groups, optimizing inter-company loan structures is also key. This level of planning is a core function of strategic CFO services.
Conclusion: A Strategic Imperative for Debt-Financed Businesses
The UAE’s Interest Capping Rules are a clear signal that tax authorities are focused on substance and the economic reality of business financing. For companies with significant debt, these regulations move tax planning beyond simple compliance into the realm of strategic capital structure management. Proactively modeling the impact of these rules, understanding the nuances of the EBITDA calculation, and planning financing activities accordingly are essential steps to manage your tax liability effectively and ensure the financial health of your enterprise.
