UAE corporate tax: adjustments, add-backs and common risks

UAE corporate tax is 0% on taxable income up to AED 375,000 and 9% above it, and it is charged on taxable income after adjustments, not on accounting profit. This page explains the add-backs that most often change the result, the free zone conditions that decide 0% or 9%, and the risks to check before you file.

What does this page cover?

This page focuses on decision-critical areas of UAE Corporate Tax, including:

0% and 9% tax rate application
Mainland vs Free Zone distinctions
Qualifying Free Zone Person (QFZP) conditions

Scenarios that trigger audit risk

It is designed for owners, CFOs and decision-makers, not as legislative commentary.

How do free zone companies lose the 0% rate?

Hypothetical examples. Figures are illustrative.

De Minimis Breach

Business Case

FZ Revenue AED 15M; NQRI AED 0.8M

Risk & Impact

Limit = lower of AED 5M or 5% of revenue (AED 0.75M here). A breach ends QFZP status from the start of the period and for the next four tax periods

Recommendation

Monitor NQRI monthly, segregate Mainland activity

Ref: MD 229/2025

Lack of Adequate Substance

Business Case

FZ entity outsources all operations

Risk & Impact

Loss of 0% status due to failure of CIGA requirements

Recommendation

Ensure UAE-based decision-making, staff and assets

Ref: Article 18

Dealing with Natural Persons

Business Case

Services provided to UAE individuals

Risk & Impact

Income becomes Non-Qualifying; counts toward De Minimis

Recommendation

Avoid B2C unless explicitly permitted

Ref: MD 229/2025

Immovable Property Income

Business Case

Residential vs Commercial rent

Risk & Impact

Income from immovable property is an excluded activity, except commercial property in a free zone let to free zone persons

Recommendation

Segregate revenue and costs

Ref: MD 229/2025

Corporate Tax is calculated after statutory add-backs, not directly from accounting profit.
