If you run a business in the UAE, corporate tax registration is no longer optional — and neither is filing your annual return. Whether you are a mainland LLC, a free zone company, or an individual crossing the turnover threshold, the Federal Tax Authority (FTA) expects a complete, accurate set of documents submitted through the EmaraTax portal. Getting that document set right the first time is the single biggest thing that speeds up approval and keeps you clear of penalties.
This guide lays out exactly what you need for corporate tax registration and, separately, for corporate tax filing (your annual return) — plus the deadlines, penalties, and common mistakes to avoid in 2026.
Quick-answer checklist
For corporate tax registration, you need:
- EmaraTax (FTA) login credentials
- Trade license copy
- Certificate of incorporation
- Memorandum of Association (MOA) or Local Service Agent (LSA) agreement
- Emirates ID and passport copies of all owners
- Emirates IDs, passports, and proof of authorisation for authorised signatories
- Email address and contact number of authorised signatories
For corporate tax filing (the annual return), you need all seven documents above, plus:
- Financial statements for the current financial period (including the bookkeeping files that support them)
- Bank statements for the current financial period
The simplest way to remember it: filing = registration documents + your financials. Once you have registered, the return is mainly about proving your numbers.
Documents required for corporate tax registration
Registration is a one-time process, but the FTA is strict about accuracy. Here is what each document is and why it matters.
- EmaraTax (FTA) login credentials. EmaraTax is the FTA’s online portal and the only place you can register and file. If you already have a VAT account, the same login works. Set this up first — everything else flows through it.
- Trade license copy. Your current, valid trade license. The most common rejection reason here is an expired license or a license whose activity or legal form no longer matches your actual business, so check the details before you upload.
- Certificate of incorporation. Confirms your company’s legal existence and formation date. Your incorporation date also determines your registration deadline, so it needs to match your other records exactly.
- Memorandum of Association (MOA) or Local Service Agent (LSA) agreement. The MOA sets out ownership and share distribution for most companies; sole establishments and certain professional licenses use an LSA agreement instead. Make sure the MOA reflects your current shareholding — an outdated MOA after an ownership change is a frequent cause of delays.
- Emirates ID and passport copies of all owners. For every owner or shareholder. Copies should be clear, in date, and legible.
- Emirates IDs, passports, and proof of authorisation for authorised signatories. The authorised signatory is the person legally empowered to act for the company with the FTA. “Proof of authorisation” typically means a power of attorney or a board resolution naming them. This is one of the most overlooked items — missing authorisation proof is a very common bottleneck.
- Email and contact number of authorised signatories. The FTA sends all official notices, approvals, and reminders here. Use an address that is actively monitored, because penalty notices land in this inbox.
Documents required for corporate tax filing (annual return)
Once you are registered and hold your Corporate Tax Registration Number (TRN), filing is an annual obligation. You will need the same seven documents from registration (for verification), plus two sets of financial records:
- Financial statements for the current financial period. Your income statement, balance sheet, and supporting bookkeeping files (ledgers, invoices, payroll records, depreciation schedules). These are the basis for calculating your taxable income, so they need to reconcile with your books. The FTA expects businesses to keep supporting records for at least seven years, so organise them properly rather than reconstructing them at deadline.
- Bank statements for the current financial period. Bank statements should reconcile with the revenue and expenses in your financial statements. Mismatches between your declared figures and your bank activity are a classic audit trigger.
Filing is mandatory even if you owe nothing. Every taxable person must submit a return — including dormant companies filing a nil return and free zone companies claiming the 0% rate.
Registration vs filing: what's actually different
Corporate tax registration | Corporate tax filing (return) | |
|---|---|---|
How often | One time | Every year |
Core documents | Legal + identity documents (items 1–7) | The same documents, plus financials |
What it proves | That your business exists and who is authorised | Your taxable income for the period |
Extra documents | None | Financial statements + bank statements |
Deadline | Based on incorporation/turnover date | 9 months after your financial year-end |
Key 2026 deadlines and penalties
Registration deadline. Companies established on or after 1 March 2024 must register within three months of incorporation. Individuals (natural persons) conducting business must register by 31 March 2026 if their turnover exceeded AED 1 million in the 2025 calendar year — note that this is turnover, not profit.
Filing deadline. Your corporate tax return must be filed, and any tax paid, within nine months of your financial year-end. For the most common case — a 31 December 2025 year-end — that means 30 September 2026. A 31 March year-end shifts the deadline to 31 December.
Penalties to avoid:
- Late registration: a fixed AED 10,000 penalty, applied automatically regardless of whether you owe any tax.
- Late filing: AED 500 per month for the first 12 months, rising to AED 1,000 per month thereafter.
- Late payment: a flat 14% per annum on unpaid tax, accruing until settled (under the penalty framework revised by Cabinet Decision No. 129 of 2025, effective 14 April 2026).
The penalty waiver worth knowing about. The FTA is currently waiving the AED 10,000 late-registration penalty for businesses that submit their first corporate tax return or annual declaration within seven months of the end of their first tax period. If you already paid the penalty and then qualify, the amount is credited back to your EmaraTax account. This applies only to your first return, so act early.
Common mistakes that delay approval or trigger penalties
- Expired or mismatched trade license — the activity or legal form doesn’t match your actual operations.
- Outdated MOA — ownership changed but the document wasn’t updated.
- Missing proof of authorisation for the signatory — no power of attorney or board resolution attached.
- Assuming free zone = exempt — Qualifying Free Zone Persons still must register and file to claim the 0% rate.
- Assuming low profit means no obligation — there is no minimum revenue threshold for registration; even dormant companies must register and file.
- Financials that don’t reconcile with bank statements — a leading cause of FTA queries and audits.
