Quick Answer
Foreign bank branches operating in Dubai pay a 20% Emirate-level tax on their adjusted taxable income under Dubai Law No. 1 of 2024, on top of the 9% federal Corporate Tax under Federal Decree-Law No. 47 of 2022. The two do not simply stack. Law No. 1 of 2024 lets a foreign bank credit the federal Corporate Tax it has already paid against its 20% Dubai tax bill, which keeps the combined burden at roughly 20% of taxable income rather than 29%. Banks licensed through the DIFC are excluded from the Dubai tax on the income they earn within or through the DIFC.

Why Dubai Taxes Foreign Banks Separately From Corporate Tax
Dubai has taxed branches of foreign banks at the Emirate level since long before federal Corporate Tax existed. When Federal Decree-Law No. 47 of 2022 introduced a nationwide 9% Corporate Tax on business profits above AED 375,000, it created an overlap: a foreign bank branch in Dubai was suddenly liable for both the Emirate’s long-standing bank tax and the new federal tax on the same income. Dubai Law No. 1 of 2024, Concerning Tax on Foreign Banks Operating in the Emirate of Dubai, was issued to modernize the old regime and, critically, to build in a mechanism that stops the same profit being taxed twice. It applies to tax periods beginning on or after 8 March 2024, with Administrative Resolution No. 107 of 2024 setting out the filing and computation detail.
Dubai is not the only Emirate with a bank-specific tax regime. Several Emirates operate their own decades-old Bank Tax Decrees that apply a flat rate, commonly 20%, to the adjusted profits of foreign bank branches. Dubai’s Law No. 1 of 2024 is the most recently updated of these, and the one this article covers in detail, but a foreign bank with branches in more than one Emirate needs to check the local decree in each location rather than assume Dubai’s rules apply UAE-wide.
Who Is Covered
Law No. 1 of 2024 applies to branches of banks incorporated outside the UAE that operate in the Emirate of Dubai, including in its free zones and special development zones. Two groups sit outside its scope:
- UAE-incorporated banks. A locally incorporated bank, even one that is foreign-owned, is not a “foreign bank” for this law. It is taxed under the standard federal Corporate Tax rules like any other UAE resident company.
- DIFC-licensed banks, for DIFC-sourced income. A foreign bank operating under a DIFC license is excluded from the 20% Dubai tax on income it earns from within or through the DIFC. That income still falls under federal Corporate Tax in the normal way; it just does not carry the additional Emirate-level layer.
A foreign bank running both a DIFC operation and a separate onshore Dubai branch has to keep the two income streams apart, because only the onshore branch profit is exposed to the 20% tax.
The 20% Rate and How Taxable Income Is Worked Out
The headline rate is a flat 20% of the bank’s annual taxable income, with no equivalent to the AED 375,000 zero-rated band that applies under federal Corporate Tax. Taxable income is built from the branch’s audited financial results, adjusted under rules set out in the law and Administrative Resolution No. 107 of 2024 for items such as:
- Exempt income excluded from the taxable base
- Unrealized gains and losses
- Head office and regional management expenses allocated to the Dubai branch
- Expenses accrued during the year, which are only deductible if they are actually paid, or the accrual is reversed, within nine months of the tax period end and are properly documented
Annual tax returns, together with audited financial statements, are due within nine months of the end of the tax period, which is normally the calendar year.
The Federal Tax Credit: How Double Taxation Is Avoided
This is the part of the law that actually matters for a bank’s bottom line. Law No. 1 of 2024 allows a foreign bank to deduct the federal Corporate Tax it has paid under Federal Decree-Law No. 47 of 2022 from its 20% Dubai tax liability for the same tax period. In practice, for a bank paying the standard 9% federal rate on the bulk of its profit, this credit brings the additional Dubai liability down to roughly 11 percentage points on top of the 9% already paid federally, so the combined effective rate lands close to 20% of taxable income rather than 29%.
The credit is not automatically an exact wash, because the federal taxable base and the Dubai taxable base are not calculated on identical rules; adjustments differ in places, and Small Business Relief or other federal reliefs (rarely relevant to a bank of this size, but relevant to the mechanics) apply only at the federal level. A bank cannot claim a refund if the federal Corporate Tax paid exceeds the 20% Dubai liability; the credit only offsets the Dubai tax down to zero, with no carryforward or cash refund of the excess.
Worked Example (Illustrative)
The figures below are an illustrative example only, not a real client case, built to show the mechanics of the credit.
| Step | Calculation | Amount (AED) |
|---|---|---|
| Branch taxable income (assume same base for both regimes, for simplicity) | – | 10,000,000 |
| Federal Corporate Tax due | 9% x (10,000,000 – 375,000) | 866,250 |
| Dubai bank tax before credit | 20% x 10,000,000 | 2,000,000 |
| Credit for federal Corporate Tax paid | Deducted from Dubai tax | (866,250) |
| Net Dubai bank tax payable | 2,000,000 – 866,250 | 1,133,750 |
| Total tax paid (federal + net Dubai) | 866,250 + 1,133,750 | 2,000,000 |
Without the credit, the branch in this example would have paid AED 2,866,250 combined, an effective rate above 28%. With the credit applied, total tax paid is AED 2,000,000, exactly 20% of taxable income. The credit does not eliminate the Emirate-level tax; it stops the federal 9% from being charged on top of it.
Federal Corporate Tax vs. Dubai’s Bank Tax, Side by Side
| Feature | Federal Corporate Tax | Dubai Bank Tax (Law No. 1/2024) |
|---|---|---|
| Legal basis | Federal Decree-Law No. 47 of 2022 | Dubai Law No. 1 of 2024 and Administrative Resolution No. 107 of 2024 |
| Rate | 0% up to AED 375,000, 9% above | Flat 20% on taxable income, no zero-rated band |
| Who it applies to | All UAE taxable persons, including bank branches | Branches of foreign-incorporated banks operating in Dubai only |
| DIFC treatment | Applies as normal, subject to Free Zone Person rules where relevant | Excluded on income earned within or through the DIFC |
| Double taxation relief | Article 47 Foreign Tax Credit for tax paid to other countries | Credit for federal Corporate Tax already paid on the same Dubai branch income |
| Filing deadline | Generally 9 months after the tax period end | 9 months after the tax period end, with audited financials |
| Record retention | 7 years | 7 years |
The two regimes are aligned on filing timelines and retention periods by design, which is precisely what makes it practical to run the federal credit calculation as part of the same annual close rather than as a separate exercise months apart.
Filing, Payment, and Records
Once a tax period closes, a foreign bank branch has nine months to file its annual tax return and audited financial statements with the Dubai Department of Finance. Records and supporting documents must be retained for seven years from the end of the relevant tax period, in line with the retention standard used under federal Corporate Tax. A bank that discovers it has under-declared or over-declared tax has 30 days from discovery to file a voluntary disclosure correcting the position, whether that means paying the shortfall or claiming a refund of the overpayment.
Penalties
| Violation | Penalty |
|---|---|
| Tax evasion | Twice the amount of tax evaded |
| Late payment | 2% of the unpaid tax or penalty for each month of delay, or part of a month |
| Penalty cap (standard) | AED 500,000 per violation |
| Penalty cap (repeat violation within 2 years) | Up to AED 1,000,000 (double the standard cap) |
| Payment following a tax audit notice | 20 days to settle the assessed amount |
A bank that disagrees with an assessment or penalty has the right to challenge it through the applicable objection process, in the same way federal Corporate Tax assessments can be disputed at the FTA level. Given the amounts involved for a bank branch, even a routine late-payment penalty can run into hundreds of thousands of dirhams quickly, since the 2% monthly charge compounds on both the tax and any earlier penalty left outstanding.
Mandatory Audit and Documentation
Foreign bank branches almost always sit above the revenue and structural thresholds that trigger a mandatory Corporate Tax audit under Ministerial Decision No. 84 of 2025, so audited financial statements are already a federal requirement in most cases, not just a Dubai-specific one. That works in the bank’s favor here: the same audited numbers used for the federal return feed directly into the Dubai computation, and a bank that keeps its federal working papers, the branch-level profit allocation, and the head-office expense apportionment in one file will find the credit calculation is mostly arithmetic rather than a second full tax exercise.
How This Fits With International Tax Planning
A foreign bank with a Dubai branch is already managing at least three layers of tax exposure: home-country tax on the parent, federal UAE Corporate Tax on the branch, and now the Dubai 20% bank tax net of the federal credit. Where the bank’s home jurisdiction also has a double tax treaty with the UAE, the interaction between that treaty, the federal Foreign Tax Credit rules under Article 47 of Federal Decree-Law No. 47 of 2022, and the Dubai Emirate-level credit needs to be modeled together, not one regime at a time, to avoid either double taxation or an under-claimed credit. Getting the order of operations wrong, for example applying a treaty credit before the Dubai credit rather than after, can leave real money unclaimed.
Frequently Asked Questions
Do foreign banks in Dubai pay both the 20% Emirate tax and the 9% federal Corporate Tax?
Yes, both regimes apply to the same branch, but Law No. 1 of 2024 lets the bank credit the federal Corporate Tax it has paid against its Dubai tax bill, so the two do not simply add together to 29%.
What is the effective combined tax rate for a foreign bank branch in Dubai?
Once the federal credit is applied, the combined effective rate lands close to 20% of taxable income, since the Dubai tax absorbs the federal amount already paid rather than sitting on top of it.
Are DIFC banks subject to the 20% Dubai bank tax?
No, not on income earned from within or through the DIFC. That income remains subject to federal Corporate Tax in the ordinary way, without the additional Emirate-level layer.
Does the 20% rate apply to UAE-incorporated banks?
No. Law No. 1 of 2024 targets branches of banks incorporated outside the UAE. A locally incorporated bank is taxed under standard federal Corporate Tax rules only.
When did Dubai’s foreign bank tax law take effect?
Law No. 1 of 2024 applies to tax periods beginning on or after 8 March 2024, with Administrative Resolution No. 107 of 2024 providing the detailed filing and computation rules.
What happens if the federal Corporate Tax paid exceeds the 20% Dubai liability?
The credit only reduces the Dubai tax down to zero. There is no cash refund or carryforward of any excess federal tax credit against future Dubai tax periods.
How long must a foreign bank branch keep its tax records in Dubai?
Seven years from the end of the relevant tax period, matching the retention period used for federal Corporate Tax records generally.
