What Counts as Net Interest Expenditure
Net Interest Expenditure is the figure the UAE's 30% EBITDA cap and AED 12 million safe harbour are actually tested against: your interest expenditure for the tax period, less your taxable interest income for the same period. Interest is not limited to bank and loan interest — the definition under Article 30 reaches amounts that are economically equivalent to interest, including financing elements embedded in leases, deferred-payment arrangements and certain Islamic finance structures. Get this figure wrong — by using gross interest, missing an interest-equivalent charge, or measuring the wrong period — and every downstream calculation, from the de-minimis test to the 30% cap to the carry-forward schedule, is built on the wrong number.

Expense minus income
Net Interest Expenditure is not your total borrowing cost — it is a net figure, computed period by period. You start with every amount that qualifies as interest expenditure for the tax period, then deduct any taxable interest income earned in that same period, such as interest on bank deposits or intercompany loans receivable. The result is the single number tested against the AED 12 million de-minimis and, if that threshold is exceeded, against the 30% EBITDA cap.
- Start with total interest expenditure incurred in the tax period.
- Deduct taxable interest income earned in the same period, not a different one.
- The result is Net Interest Expenditure — the figure the cap actually applies to.
- A business with more interest income than expense has no net interest issue at all.
- Recompute the figure every tax period; it is not a one-off calculation.
- Keep supporting schedules — the FTA can ask you to reconcile the net figure to your accounts.
More than bank loans
The definition of interest under the general interest deduction limitation rule is deliberately wide, because a narrow definition would be easy to plan around. It captures ordinary bank and loan interest, but also amounts that are economically equivalent to interest even where they are not labelled that way in an agreement — the financing element of a deferred payment, the profit-rate return on certain Islamic finance instruments, and finance charges embedded in a lease. Reviewing every financing arrangement, not just loan agreements, is the only way to be confident your net interest figure is complete.
- Conventional bank and third-party loan interest.
- Interest on related-party and shareholder loans.
- Amounts economically equivalent to interest, however they are labelled.
- Financing elements of instalment and deferred payment arrangements.
- Profit-rate payments on Sharia-compliant financing that function as interest.
- Finance charges embedded within lease payments.
Putting the formula to work
Take a Dubai trading company with AED 9 million of bank loan interest for the period and AED 1.2 million of interest income earned on surplus cash held on deposit. Its Net Interest Expenditure is AED 7.8 million — comfortably under the AED 12 million de-minimis, so the 30% cap never needs to be calculated. Remove the interest income, say the deposit matures and is not renewed, and net interest rises to AED 9 million — still under the threshold, but the margin has narrowed. This is why the netting calculation should be revisited every period rather than assumed to still hold.
- Interest expenditure and interest income can each change materially year to year.
- A comfortable de-minimis margin one year is not guaranteed the next.
- Recalculate net interest at each filing rather than carrying forward last year's conclusion.
- Small changes in interest income can be as important as changes in borrowing.
Getting the figure right the first time
Most disputes over the interest cap start with a disagreement about what belongs in the net interest figure, not with the 30% calculation itself. Exiloz reviews your loan agreements, lease contracts, Islamic finance documentation and intercompany arrangements to identify every amount that is interest or economically equivalent to interest, then nets it against your taxable interest income for the period. We document the workings so the figure holds up if the FTA asks for support.
- Full review of loan, lease and financing agreements for interest-equivalent amounts.
- Netting against taxable interest income for the correct tax period.
- A documented workpaper you can produce on request.
- Ongoing monitoring as financing arrangements change.

Frequently Asked Questions
Getting Net Interest Expenditure right is the foundation for the entire interest limitation calculation — here is what Dubai businesses ask us most often when working out their figure.
Is only bank interest counted?
No. The definition is deliberately broad and reaches amounts economically equivalent to interest, not just amounts labelled as bank or loan interest. Financing elements of leases, deferred payment terms and certain Islamic finance structures can all fall inside the definition. If you only review loan agreements, you risk understating your net interest figure.
Do I net off interest income?
Yes. Net Interest Expenditure is interest expenditure for the tax period less taxable interest income for the same period, not your gross borrowing cost. This netting can make a meaningful difference for businesses holding significant cash balances or intercompany loans receivable. Always match the periods — income and expense must relate to the same tax period.
Why does the definition matter?
It determines whether your net interest exceeds the AED 12 million de-minimis and, if so, exactly how much is subject to the 30% EBITDA cap. Understating the figure risks a return that does not match your true position; overstating it risks restricting interest you never needed to restrict. Both outcomes create problems if the FTA reviews the calculation.
Can Exiloz compute the figure?
Yes. We identify all in-scope interest across your loan, lease and financing arrangements and calculate your net figure with full supporting workings for each tax period.
Does the definition include non-bank financing costs?
Yes, where they are economically equivalent to interest. Finance-lease charges, the financing element of deferred payment arrangements, and profit-rate payments on certain Islamic finance instruments can all be captured, even though none of them is called "interest" in the underlying agreement.
Is net interest measured annually or per tax period?
It is measured per tax period, which for most UAE businesses aligns with their financial year. Each period is assessed independently, so a comfortable position in one period does not carry over automatically to the next.
What if my interest income exceeds my interest expenditure?
Then your Net Interest Expenditure is nil for the period, and neither the de-minimis test nor the 30% cap is relevant. This is common for businesses holding significant cash reserves or intercompany receivables alongside modest borrowing.
Do I need to separately identify interest on every financing arrangement?
Yes. Each loan, lease and financing arrangement needs to be reviewed individually to confirm whether it produces interest or an interest-equivalent amount before the amounts are aggregated and netted for the period.
Measure your net interest expenditure precisely
Exiloz reviews every loan, lease and financing arrangement to identify all in-scope interest, nets it against your taxable interest income, and produces a documented net interest figure for each tax period — the foundation the rest of your interest-cap calculation depends on.
