Foreign banks operating in Dubai face a tax framework that is different from the rules applying to most ordinary UAE businesses.
The main legislation is Law No. (1) of 2024 Concerning Tax on Foreign Banks Operating in the Emirate of Dubai. It replaced the older 1996 framework and introduced clearer rules on taxable income, tax payments, audits, voluntary disclosures, penalties and disputes.
Under the Dubai foreign bank tax law, qualifying foreign banks are subject to tax at 20% of their annual taxable income. But that does not mean they simply pay 20% on top of UAE Corporate Tax. Federal Corporate Tax paid by the foreign bank can be deducted when calculating the Dubai tax liability, subject to the conditions in the law.
If you operate a foreign bank branch in Dubai, the details matter. How you allocate head-office costs, account for shared revenue and treat unrealised gains can directly affect the taxable amount.
Here is what you need to know.
What Is the Dubai Foreign Bank Tax Law?
The current framework is based on Dubai’s Law No. (1) of 2024 on the Taxation of Foreign Banks.
The law applies specifically to a foreign bank, defined as a branch of a foreign bank licensed by the Central Bank of the UAE to operate in the country.
It applies to foreign banks operating throughout Dubai, including those in special development zones and free zones. There is one major exception: foreign banks licensed to operate in the Dubai International Financial Centre, or DIFC, are outside the scope in relation to income generated from conducting their business within or through the DIFC.
A foreign-owned finance company, fintech business, insurance company or investment company does not automatically fall under the Dubai foreign bank tax regime simply because it operates in financial services. The entity must fall within the law's definition of a foreign bank.

Who Is Subject to the Dubai Foreign Bank Tax?
The law generally covers branches of foreign banks that:
are licensed by the Central Bank of the UAE
operate in the Emirate of Dubai
conduct banking activities outside the DIFC exemption described in the law
The Central Bank of the UAE banking regulations also apply regulatory requirements to branches of foreign banks operating in the UAE. Foreign bank branches therefore have to consider both their banking-regulatory obligations and applicable tax requirements.
For groups that have more than one UAE operation, it is important to identify which income belongs to the Dubai taxable branch rather than treating the regional operation as one simple tax pool.
What Is the Tax Rate for Foreign Banks in Dubai?
The headline rate is 20% of taxable income. However, Article 4 of Law No. 1 of 2024 allows the Corporate Tax rate applicable under the UAE Corporate Tax Law to be deducted from the Dubai rate, provided the relevant Corporate Tax has been paid.
Administrative Resolution No. 107 of 2024 gives the calculation as:
Dubai tax due = 20% × Taxable Income − equivalent Corporate Tax paid
This is intended to coordinate the Dubai banking tax with the federal Corporate Tax system instead of simply stacking one full tax on top of the other.
Simple example
Suppose a foreign bank branch has taxable income of AED 10 million.
At 20%, the Dubai tax calculation begins at:
AED 10 million × 20% = AED 2 million
The bank must then account for the qualifying Federal Corporate Tax it has actually paid and provide supporting evidence for the deduction.
The exact final liability therefore depends on the bank's federal Corporate Tax position and the amount attributable to the relevant branch.
How Is Taxable Income Calculated?
This is one of the most technical areas of the Dubai foreign bank tax law. The legislation does not simply take the accounting profit shown on the branch's income statement and multiply it by 20%.
Administrative Resolution No. 107 of 2024 sets detailed rules for calculating taxable income, including how foreign banks should deal with:
shared revenues
shared expenses
regional management expenses
centralised head-office expenses
unrealised gains and losses
expected credit losses
allowances and provisions
related branch interest
depreciation and amortisation
accrued expenses
These items deserve close attention because foreign banks often operate with centralised treasury, management, technology and risk functions that serve several countries or branches.
Shared Revenue and Expenses
Shared revenue cannot simply be assigned to whichever branch is convenient. For certain shared income and expenses, the Resolution requires allocation formulas based on factors such as monthly average assets and liquidity transfers.
The calculations must also be audited by an accredited external auditor and reflected in the notes accompanying the financial statements.
Head-Office and Regional Management Costs
Regional and central management expenses may be deductible, but the bank needs to demonstrate that the allocation is reasonable under the prescribed formulas. For example, the Resolution compares the proportion of management expenses allocated to a Dubai taxable branch with the corresponding interest revenue ratios.
If the amount allocated to the Dubai branch exceeds the permitted proportion, the excess may be disallowed for tax purposes.
That makes inter-branch cost allocation more than an internal accounting exercise. It becomes part of tax compliance.
What Happens to Unrealised Gains and Losses?
Administrative Resolution No. 107 of 2024 also deals directly with unrealised positions.
In general, tax is not calculated on unrealised gains or profits recorded in the financial statements until those gains or profits are realised. The same principle works in the other direction. Unrealised losses cannot generally be deducted from the tax base until they are realised.
This matters for banks holding financial instruments whose accounting values can move significantly during a reporting period.
What Are the Filing and Payment Deadlines?
The tax period is generally the foreign bank's financial year.
The Resolution states that the first tax period under the current framework commenced on 1 January 2024. The Department of Finance may permit changes to a bank's tax period in accordance with approved conditions.
Two deadlines need to be tracked carefully:
Requirement | General Deadline |
Dubai foreign bank tax payment | Within 3 months after the end of the tax period |
Tax return and supporting documents | Within 9 months after the end of the tax period |
The tax return must be certified by the responsible officer of the taxable bank and an external auditor. Supporting documents and audited financial information must also be provided.
For current federal rules and decisions, banks should separately monitor the Federal Tax Authority Corporate Tax legislation portal.
What Records Must Foreign Banks Keep?
Foreign banks need strong supporting documentation.
Under Law No. 1 of 2024, tax-related records and documents must generally be retained for at least seven years from the end of the relevant tax period.
Banks should maintain clear records covering areas such as:
taxable income calculations
UAE Corporate Tax payments
audited financial statements
head-office expense allocations
regional management expense allocations
shared income calculations
shared expense calculations
inter-branch transactions
provisions and credit-loss calculations
deferred tax assets
Administrative Resolution No. 107 also requires a dedicated register for deferred tax assets that can be produced during a tax audit.

What Are the Penalties for Non-Compliance?
Dubai has introduced specific administrative penalties for foreign banks through Executive Council Resolution No. 101 of 2024.
Examples include:
Violation | Penalty |
Late submission of returns, forms or required supporting documents | AED 1,000 per day |
Incorrect or non-compliant forms or documents | AED 20,000 per affected document |
Failure to notify authorities of address/contact changes | AED 20,000 |
Failure to notify cessation of banking operations | AED 20,000 |
Breach of DOF or FAA instructions | AED 10,000 |
Repeated administrative violations within two years can result in the fine being doubled, subject to a maximum of AED 1 million under the Resolution.
Law No. 1 of 2024 also imposes a separate late-payment penalty of 2% of unpaid tax or fines for every month of delay, with part of a month rounded up to a full month.
Tax evasion carries much greater exposure. The law provides for a fine equal to twice the amount of tax evaded in qualifying cases.
Can a Foreign Bank Correct an Incorrect Return?
Yes. If a bank discovers that a tax return or assessment contains an error that causes tax to be understated, it must submit a voluntary disclosure and pay the outstanding difference within 30 days of becoming aware of the error.
Where an error results in overpaid tax, a voluntary disclosure may also be submitted. The bank can request a refund or have the amount treated as an advance payment against a future tax period.
Banks should correct problems early. Waiting until an audit starts can expose the institution to additional penalties.
Can a Bank Challenge a Dubai Tax Assessment?
A foreign bank can challenge tax or fines imposed under the law. The challenge generally has to be:
submitted in writing
supported by facts and documents
filed within 20 days of notification
accompanied by payment of at least 50% of the disputed tax or fine
A dedicated committee considers qualifying challenges before recommendations go to the Supreme Fiscal Committee.
The appeal timetable is short, so tax teams should have an internal escalation process ready before an assessment arrives.
Conclusion
The Dubai foreign bank tax law creates a dedicated tax regime for foreign bank branches operating in the Emirate.
The headline rate is 20%, but the actual calculation is more detailed because qualifying Federal Corporate Tax paid can be deducted. Banks must also follow specific rules for shared revenues, head-office expenses, unrealised gains and losses, provisions and related branch transactions.
Compliance goes beyond calculating the final tax bill. Foreign banks need audited financial information, supporting allocation schedules, proper records and close control of payment and filing deadlines.
With penalties reaching significant amounts and detailed audit powers available to the Dubai authorities, accurate documentation should be built into the bank's annual tax process rather than prepared only when an audit begins.
