ADGM Corporate Tax Registration and Filing

Registering for Corporate Tax is one of the first obligations of every ADGM company — and failing to do it on time carries fixed penalties even when you owe no tax. This guide explains the registration process, deadlines, penalties, and filing requirements under the UAE Corporate Tax regime.

1. Register on EmaraTax

Corporate Tax registration and filing are handled through the EmaraTax portal (emaratax.gov.ae), the same platform used for VAT and Excise Tax.

For an ADGM company, the registration process involves:

1. Creating / accessing your EmaraTax account.
2. Selecting the Corporate Tax registration type.
3. Providing your Trade Licence details and incorporation date.
4. Entering authorised-signatory and contact information.
5. Submitting financial year-end and banking details.
6. Confirming the entity type and any group / related-party structure.

Registration is generally straightforward and, in most cases, the Tax Registration Number (TRN) is issued quickly.

2. Registration Deadlines

The Federal Tax Authority sets specific registration deadlines based on the entity's incorporation or licensing date. As a general rule:

• Existing companies (incorporated before the CT regime began) were given staggered deadlines based on licence month.
• Newly incorporated companies must register within a set period — often 3 months from incorporation, but always confirm the current deadline on the FTA website for your incorporation date.

Missing the deadline triggers an automatic penalty.

3. Penalties

The penalty regime under Cabinet Decision No. 49 of 2023 (as updated) includes:

• Late registration: AED 10,000
• Late filing of a return: AED 500 for the first late filing, AED 1,000 for repeated late filings within 24 months
• Late payment of tax due: AED 500 for the first time, AED 1,000 for repeated defaults
• Failure to keep records: AED 10,000
• Failure to issue tax invoices / tax credit notes: AED 2,500 per instance
• Non-compliance with record-keeping or other administrative duties: varies

The AED 10,000 late-registration penalty applies even if your company owes zero tax and even if it is entirely a qualifying free zone entity. Registration is mandatory and not optional.

A late-payment penalty is also supported by a 14% monthly surcharge on unpaid tax, capped at 100% of the unpaid amount.

4. The Filing Deadline

Your Corporate Tax return must be filed within 9 months after the end of your financial year (FY). The filing deadline is also the payment deadline for any tax due.

Example:

• Financial year ends 31 December 2025
• Filing and payment deadline: 30 September 2026

There is no separate extension request — the 9-month window is fixed.

5. What to File

A Corporate Tax return typically includes:

• Taxable income calculation (after deductible expenses)
• Qualifying Free Zone Person declaration and qualifying-income breakdown (if applicable)
• Transfer pricing disclosure for related-party transactions
• General information about the entity and ownership

Even if your company has no taxable income, you must still file a nil return — a failure to file is a failure regardless of tax owed.

6. Records to Keep

You must retain records for 7 years (and, for tax losses, longer in some cases). Records include:

• Financial statements and trial balances
• Bank statements
• Invoices and contracts
• Payroll and HR records
• Related-party agreements and transfer-pricing documentation
• The written QFZP assessment (qualifying vs non-qualifying income)

ADGM companies must also produce audited financial statements annually using an ADGM-approved auditor, which dovetails directly with the records required for the CT return.

7. Practical Timeline for ADGM Founders

Summary

• Register early — the AED 10,000 late-registration penalty is the most common, most avoidable fine.
• File within 9 months of your FY-end, every year, even as a nil return.
• Keep records for 7 years and produce audited accounts.
• Document your QFZP status so your return and audit are consistent.

A disciplined, calendar-driven approach keeps your ADGM company fully compliant and penalty-free.
