Compliance with corporate tax is one of the most vital pieces for companies that operate in the mainland of the UAE. The regime was introduced under the Federal Decree-Law No. 47 of 2022 and applies to most businesses registered with the Department of Economic Development (DED). Understanding how corporate tax works will help new and existing businesses meet their obligations and avoid penalties.This guide explains how corporate tax for mainland businesses works, where mainland areas are located in Dubai, how to register, and what companies must do to stay compliant.
Understanding Corporate Tax for Mainland Business
Corporate tax in the UAE applies to most mainland companies, including LLCs, civil companies, partnerships, and branches of foreign entities. These fall within the ambit of UAE federal laws and the local economic departments. The current framework for corporate tax supports the wider United Arab Emirates economy and ensures conformance with international standards, as well as adherence to the global tax principles introduced under the OECD’s Pillar Two rules for large multinational corporations.
Under the UAE Corporate Tax Law:
- The first AED 375,000 of taxable income is taxed at a rate of 0%
- Everything above that level is taxed at 9% of the amount earned.
- The only industries that have different regulations in place are the extractive industries and some government-related agencies.
Where are the Mainland Business Areas in Dubai?
The DED-licensed mainland companies can operate anywhere within Dubai. The most common commercial areas are:
- Business Bay
- Sheikh Zayed Road
- Deira
- Downtown Dubai
- Bur Dubai
These zones are within the larger economic area of the mainland, where companies can trade across the UAE with no restrictions.

What is the Difference between Corporate Tax for Mainland and Free Zone Companies ?
| Criteria | Mainland Business | Free Zone Company |
|---|---|---|
| Tax Rate | 0% up to AED 375,000; 9% above | 0% for qualifying income; 9% for non-qualifying income |
| Scope of Tax | Worldwide income | Depends on qualifying rules |
| Regulatory Authority | DED | Free Zone Authority |
| Eligibility for 0% | Up to AED 375,000 only | Only if conditions for Qualifying Free Zone Person (QFZP) are met |
| Economic Substance | Required | Mandatory for QFZP status |
