How branch registration works under UAE corporate tax

What is branch registration under UAE corporate tax?

Branch registration under UAE corporate tax is the process of declaring a branch to the Federal Tax Authority (FTA) so its income is included in the head office's corporate tax filing. A branch is not a separate legal entity, so the parent company registers once and reports branch results inside its own return under Federal Decree-Law 47 of 2022.

If you run a UAE business with one or more branches, your UAE corporate tax position depends on whether each branch is a legal extension of the head office or a separate legal entity. This guide explains the rules, the EmaraTax steps, and the documents you need. It covers mainland branches, free zone branches, and foreign company branches operating in the UAE.

The legal basis for branch treatment

Federal Decree-Law 47 of 2022 treats a branch as part of its head office for corporate tax. That means the head office holds one Tax Registration Number (TRN) and reports the combined taxable income of itself and all its branches. Branches do not get their own TRN and do not file separate corporate tax returns.

This applies whether the branch is in the same emirate, a different emirate, or a free zone. The principle is simple: one legal person, one corporate tax registration. Federal Decree-Law 17 of 2024 on tax procedures sets the wider compliance framework around this.

What counts as a branch

A branch is a place of business that operates under the same trade licence number or as a registered extension of an existing UAE legal entity. Common forms include:

• A mainland LLC opening a second branch licence in the same emirate.
• A Dubai company registering a branch in Abu Dhabi or Sharjah.
• A free zone company opening a mainland branch, or vice versa.
• A foreign company registering a UAE branch with the Ministry of Economy.

What is not a branch

A subsidiary is a separate legal entity, even if it is fully owned by the parent. Subsidiaries must complete their own UAE Corporate Tax Registration and file their own returns. The same applies to joint ventures with their own legal personality.

How head office and branches are taxed together

The head office consolidates the revenue, expenses, assets, and liabilities of all its UAE branches into one set of financial statements. Corporate tax is then calculated on the combined taxable income.

The standard rates apply to the total, not to each branch:

DMTT means Domestic Minimum Top-up Tax, which applies to in-scope multinational groups under the OECD Pillar Two rules. Most UAE SMEs will sit in the first two bands.

Small business relief and branches

Small business relief is available where group revenue is up to AED 3 million per tax period, through 2026. The revenue test looks at the head office and all its branches combined. You cannot split revenue across branches to stay under the threshold.

Free zone branches

If your head office is a Qualifying Free Zone Person (QFZP), the branch is part of the same legal person and follows the same status. A mainland branch of a free zone company will generally not be a QFZP for activities carried on through that mainland branch, and income from it is usually taxed at 9%. For the detail, see our guide on Corporate Tax Registration for Free Zone Companies.

When does a UAE business with branches need to register?

The head office registers once on EmaraTax. Branches do not register separately for corporate tax, even if each branch has its own commercial licence. You file using the head office's TRN.

The trigger to register is the same as for any taxable person: the business must register with the FTA based on the timeline set by Ministerial Decision. Check our page on the UAE Corporate Tax Registration Deadline to confirm the date that applies to your licence issue month.

Foreign companies with a UAE branch

A foreign company that operates in the UAE through a branch creates a Permanent Establishment in the UAE. The branch must be registered for corporate tax in the UAE, with the foreign head office named as the taxable person. The branch's UAE-sourced income is taxed at the standard rates above AED 375,000.

UAE companies with foreign branches

A UAE company that opens a branch abroad still files in the UAE on its worldwide income. It can elect for a foreign branch exemption under Article 24 of the Corporate Tax Law if conditions are met, or claim a foreign tax credit. The election is made on a per-jurisdiction basis.

How to register on EmaraTax when you have branches

The process is the same as any corporate tax registration, with extra steps to declare branches. You can read the full walkthrough on How to Register Corporate Tax UAE Online, but here is the branch-specific flow.

1. Log in to EmaraTax using the head office's UAE Pass or email account.
2. Open the corporate tax registration form for the legal entity.
3. Enter the head office trade licence as the main licence.
4. In the business activities section, add each branch licence as an additional licence under the same legal entity.
5. List the address, activity, and licence number for every branch.
6. Upload documents for the head office and each branch.
7. Submit and wait for the FTA's approval and TRN.

For a screen-by-screen walkthrough, our EmaraTax Corporate Tax Registration Guide covers each tab and field.

What if a branch was set up after registration?

If you open a new branch after you have already registered, update your EmaraTax profile within 20 business days. Go to the taxable person dashboard, edit the registration, add the new branch licence, and upload its documents. Failure to keep records current can trigger administrative penalties under tax procedures law.

Documents required for branch registration

You need head office documents plus a parallel set for each branch. The list below is a working checklist. For the full version, see our page on Corporate Tax Registration Documents Required.

The financial year must be the same for the head office and all branches because they file as one taxable person.

Filing, bookkeeping, and record keeping

Records must be kept for 7 years from the end of the relevant tax period. The head office is responsible for keeping records for all branches. In practice, this means you should:

• Maintain separate ledgers per branch for internal control.
• Consolidate at year end into one set of statements.
• Eliminate intercompany transactions between head office and branches.
• Allocate shared costs on a documented basis.

Corporate tax returns are due within 9 months of the financial year end. So a company with a December year end must file by 30 September of the following year. VAT returns remain due within 28 days of the period end, and the head office's VAT TRN covers all branches.

Intercompany transactions between branches

Movements of cash, goods, or services between a head office and its own branch are not taxable supplies for corporate tax. They are internal transfers within one legal person. You still need to record them, but they wash out on consolidation. Transfer pricing rules under Article 34 apply to dealings with related parties that are separate legal entities, not to internal branch transfers.

Common mistakes to avoid

• Registering each branch as a separate taxable person. Only the head office registers.
• Using different financial year ends for head office and branches.
• Forgetting to add a new branch licence within 20 business days.
• Splitting revenue across branches to claim small business relief.
• Treating internal branch transfers as taxable revenue.
• Missing the registration deadline for the legal entity, which triggers penalties from AED 10,000.

Once your corporate tax registration covers every branch, plan ahead for e-invoicing. The UAE is rolling out a Peppol 5-corner DCTCE (Decentralized Continuous Transaction Control and Exchange) model, with the PINT AE format. Phase 1 mandatory go-live is 1 January 2027 for businesses with AED 50 million or more revenue, and 1 July 2027 for SMEs. The same head office TRN you register today will drive your future e-invoicing too. See the UAE Corporate Tax hub for related reading.
