UAE Corporate Tax Registration 2026: Avoid Penalties

UAE Corporate Tax Registration 2026: Register Before the AED 10,000 Penalty

9 min read

Quick Answer

Corporate Tax registration in the UAE is mandatory for all businesses under Federal Decree-Law No. 47 of 2022. Register through the FTA EmaraTax portal at eservices.tax.gov.ae within 3 months of company incorporation. The FTA approves applications in 5 to 15 business days. Missing the deadline triggers an AED 10,000 penalty. This is waivable if you file your first Corporate Tax return within 7 months of the end of your first tax period, not by one fixed date for every business.

If you own a business in the UAE, Corporate Tax registration is now mandatory. Whether you operate in Dubai, Abu Dhabi, Sharjah, or any free zone, you must register with the Federal Tax Authority (FTA) through the EmaraTax portal. Many people still ask is Dubai tax free — the answer is no for businesses, and corporate tax registration is the first compliance step.

In this guide, Qaspro Global explains how to register for Corporate Tax in the UAE, required documents, deadlines, penalties, and how to ensure full compliance in 2026. If you are setting up a new company, see our complete business setup in Dubai 2026 guide for the full process from company formation through tax registration.

Did you know? Even if you got your trade license only for a visa, you must still register and file corporate tax. Certain entities such as government bodies, investment funds, and pension funds may qualify as exempt persons under UAE corporate tax law and are not subject to corporate tax at all.

What Is UAE Corporate Tax?

UAE Corporate Tax is a federal tax on business profits introduced under Federal Decree-Law No. 47 of 2022, effective for financial years starting on or after 1 June 2023. The standard rate is 9% on taxable income above AED 375,000, with 0% on income up to that threshold.

Corporate Tax Rate in UAE:

0% on taxable income up to AED 375,000
9% on taxable income above AED 375,000
0% for Qualifying Free Zone Persons (QFZP) on qualifying income

Even if your profit is below AED 375,000, Corporate Tax registration in UAE is still compulsory.

Who Must Register for Corporate Tax in UAE?

Every business operating in the UAE must register for corporate tax with the FTA, regardless of profit level, size, or whether tax is actually payable. You must register if you are:

Mainland company in UAE (LLC, sole establishment, civil company)
Free zone company (including QFZP applicants)
Offshore company conducting UAE business
Foreign company with UAE branch or permanent establishment under Cabinet Decision No. 35 of 2025
Natural person with UAE-sourced business income exceeding AED 1 million — see: UAE Corporate Tax for Natural Persons and Individuals 2026
Sole proprietor with a UAE trade license earning over AED 1 million — see: UAE Sole Proprietor Corporate Tax 2026: The AED 1M Rule Explained

Many business owners wrongly assume free zone companies are exempt. Free zone companies may qualify for 0% Corporate Tax under the QFZP regime, but registration is still required. Freelancers earning above AED 1 million in business income are treated as natural persons subject to corporate tax and must register with the FTA.

What Are the Corporate Tax Registration Deadlines in UAE 2026?

The FTA assigned registration deadlines based on trade license issuance month under FTA Decision No. 3 of 2024. For businesses incorporated in 2025 and 2026, the rule is simple: register within 3 months of your incorporation date. See the full picture of every UAE tax deadline in 2026 to stay compliant across all your obligations.

New businesses in 2025 to 2026: Must register within 3 months of incorporation

License issuance month (any year)	Registration deadline
January or February	31 May 2024
March or April	30 June 2024
May	31 July 2024
June	31 August 2024
July	30 September 2024
August or September	31 October 2024
October or November	30 November 2024
December	31 December 2024

These dates apply to resident companies licensed before 1 March 2024 and have all passed. A company without a license on 1 March 2024 had until 1 June 2024. A late applicant faces the AED 10,000 administrative penalty.

Deadlines for other taxpayer types

Resident companies incorporated, established or recognised on or after 1 March 2024: within 3 months of that date.
Foreign entities effectively managed and controlled in the UAE: within 3 months of the end of their financial year.
Non-resident companies with a permanent establishment: within 9 months if it existed before 1 March 2024, or 6 months from the date it came into existence on or after that date.
Non-resident companies with a nexus in the UAE: within 3 months of 1 March 2024, or within 3 months of the date the nexus is established.
Natural persons doing business in the UAE with turnover above AED 1 million in a calendar year: by 31 March of the following year (residents) or within 3 months of meeting the requirements (non-residents).

Missing your Corporate Tax registration deadline results in an administrative penalty of AED 10,000. However, the FTA runs a late registration penalty waiver: the AED 10,000 is waived automatically, with no separate request, if you submit your first Corporate Tax return within seven months of the end of your first tax period (instead of nine). For a calendar-year business whose first tax period ended 31 December 2025, that seven-month window closed on 31 July 2026. If your first tax period ends on a later date, your own seven-month window runs from that date. Source: Federal Tax Authority announcement of 14 May 2026.
