Mainland and Free Zone companies are both within the UAE Corporate Tax framework, but their tax treatment can differ. Mainland companies generally follow the standard 0% and 9% rates, while a Free Zone company may qualify for 0% Corporate Tax on qualifying income if it meets strict conditions. Free Zone status alone does not guarantee a 0% tax rate.
For businesses that want a broader review of their obligations, Beaufort Associates’ UAE Corporate Tax services cover registration, return filing, consultancy and readiness support.
Key Takeaways
- Mainland companies generally follow the standard 0% and 9% Corporate Tax rates.
- Free Zone status does not automatically provide a 0% Corporate Tax rate.
- A Qualifying Free Zone Person can apply 0% only to qualifying income and 9% to taxable income that is not qualifying income.
- The de minimis threshold for non-qualifying revenue is the lower of AED 5 million or 5% of total revenue, subject to the applicable calculation rules.
- Qualifying Free Zone Persons must maintain audited financial statements and meet the other ongoing qualifying conditions.
- Both mainland and Free Zone companies generally have Corporate Tax registration, record-keeping and return filing obligations where they fall within the regime.

What is the Main Difference Between Mainland and Free Zone Corporate Tax?
The key difference is the tax regime that may apply. A mainland company normally uses the standard UAE Corporate Tax rates. A Free Zone Person can access the special Free Zone regime only if it qualifies as a Qualifying Free Zone Person and continues to satisfy the legal conditions for that status.
“Mainland” is a common business term rather than a separate category in the Corporate Tax Law. In practice, companies established outside a Free Zone generally apply the standard Corporate Tax rules, while entities established in a Free Zone must assess whether the special Free Zone regime applies to them.
Mainland vs Free Zone Corporate Tax at a Glance
The section below summarises the main differences under the rules in force as at September 2026. The exact treatment depends on the company’s activities, income, structure and eligibility for reliefs.
1. Basic Tax Treatment
Mainland Company
Generally 0% on taxable income up to AED 375,000 and 9% on taxable income above AED 375,000.
Free Zone Person
A Qualifying Free Zone Person can benefit from 0% on qualifying income and 9% on taxable income that is not qualifying income. A non-qualifying Free Zone Person generally falls under the standard regime.
2. AED 375,000 0% band
Mainland Company
Generally available under the standard rate rules.
Free Zone Person
A Qualifying Free Zone Person does not receive the AED 375,000 0% band on non-qualifying taxable income.
3. Special Eligibility Conditions
Mainland Company
No Free Zone qualification test. General Corporate Tax rules still apply.
Free Zone Person
Must satisfy the Qualifying Free Zone Person conditions, including substance, qualifying income, transfer pricing, de minimis and audited financial statement requirements.
4. Small Business Relief
Mainland Company
May be available to an eligible resident person where the conditions are met.
Free Zone Person
A Qualifying Free Zone Person cannot elect Small Business Relief.
5. Return filing
Mainland Company
Generally required where the company is a taxable person.
Free Zone Person
Required even where qualifying income is taxed at 0%.
How Does Corporate Tax Apply to Mainland Companies?
A mainland company generally calculates taxable income under the standard Corporate Tax rules. The standard rate is 0% on taxable income up to AED 375,000 and 9% on taxable income above AED 375,000, subject to the Corporate Tax Law, available exemptions, reliefs, deductions and other adjustments.
For example, if a mainland company has taxable income of AED 1,000,000 and no special adjustments or credits, the first AED 375,000 is taxed at 0% and the remaining AED 625,000 is taxed at 9%. The final Corporate Tax payable can change where tax losses, exemptions, tax credits or other provisions apply.
Eligible resident businesses may also consider Small Business Relief where the applicable revenue and other conditions are met. Under the current rules, the relief can apply to eligible Tax Periods (the financial period for which Corporate Tax is calculated and filed) ending on or before 31 December 2029, subject to the AED 3 million revenue threshold and the other conditions. This relief is separate from the Free Zone regime.
How Does Corporate Tax Apply to Free Zone Companies?
A Free Zone company is not automatically exempt from Corporate Tax. A Free Zone Person that meets the conditions to be a Qualifying Free Zone Person can benefit from 0% Corporate Tax on qualifying income. Taxable income that does not qualify is generally subject to 9%. If the qualifying conditions are not met, the standard Corporate Tax regime can apply.
The Free Zone rules can be technical. Corporate Tax consultancy in the UAE can help a business review its activities, customer types, income streams and eligibility before it relies on the 0% Free Zone rate.
When Can a Free Zone Person Benefit From 0% Corporate Tax?
A Qualifying Free Zone Person (a Free Zone business that meets the conditions for the special Corporate Tax regime) can apply the 0% rate only to qualifying income. The classification depends on factors such as the type of activity, the counterparty, whether a Free Zone counterparty is the beneficial recipient (the person that actually uses and enjoys the relevant goods or services), and whether the income falls within an excluded activity (an activity that does not qualify for the special 0% treatment). The current qualifying and excluded activity rules are set out in Ministerial Decision No. 229 of 2025.
Income from transactions with non-Free Zone customers can still qualify in some cases, but generally only where it arises from specified qualifying activities and is not from an excluded activity. This means a Free Zone company should not assume that all overseas income, all Free Zone income or all mainland customer income automatically receives the 0% rate.
What is the De Minimis Rule?
A Qualifying Free Zone Person is permitted a limited amount of non-qualifying revenue without automatically losing the special regime. The de minimis requirement is met where non-qualifying revenue does not exceed the lower of AED 5 million or 5% of total revenue, subject to the specific exclusions and calculation rules.
If the Free Zone Person fails a qualifying condition, the consequences can extend beyond the current period. Under the current rules, it can cease to be a Qualifying Free Zone Person from the beginning of that tax period and for the subsequent four tax periods, subject to the applicable legislation.
What Conditions Must a Qualifying Free Zone Person Meet?
A Free Zone company must meet more than a location test to obtain the special 0% treatment. The Corporate Tax Law and implementing decisions require a Qualifying Free Zone Person to satisfy several ongoing conditions throughout the relevant tax period.
- Maintain adequate substance, including carrying out core income-generating activities (the key activities that generate business income) in the relevant Free Zone or Designated Zone (a Free Zone treated as a Designated Zone under UAE VAT rules), where required, with adequate assets, qualified employees and operating expenditure for the activity.
- Derive qualifying income in accordance with the applicable Cabinet and Ministerial Decisions.
- Not elect to be subject to the standard Corporate Tax regime where it intends to retain Qualifying Free Zone Person treatment.
- Comply with the arm’s length principle and the relevant transfer pricing requirements.
- Keep non-qualifying revenue within the de minimis threshold.
- Prepare and maintain audited financial statements. Ministerial Decision No. 84 of 2025 requires a Qualifying Free Zone Person to prepare and maintain audited financial statements, regardless of the general AED 50 million revenue threshold that applies to certain other taxable persons.
Can a Free Zone Company Trade With Mainland Customers?
Yes. A Free Zone company can have mainland customers, but the Corporate Tax treatment of that income must be analysed. Income from a non-Free Zone person is not automatically qualifying income merely because the supplier is based in a Free Zone. The relevant activity and the Free Zone rules must be tested.
For a Qualifying Free Zone Person, income from a mainland customer can qualify where it is derived from a qualifying activity and is not an excluded activity. Other income may be non-qualifying and can affect the de minimis test. The contractual flow, actual activity and source of income should therefore be reviewed before filing.
Do Mainland and Free Zone Companies Both Need to Register and File?
Yes, companies within the Corporate Tax regime generally need to meet the applicable registration and filing obligations whether they operate on the mainland or in a Free Zone. A 0% rate does not by itself remove the obligation to register, maintain records or file a Corporate Tax return.
After registration, businesses can use Corporate Tax return filing services to review the accounts, tax adjustments, disclosures and Free Zone schedules before submission through EmaraTax.
Businesses that are not yet registered can review the current requirements through Beaufort Associates’ Corporate Tax registration support.
Which is More Tax Efficient: Mainland or Free Zone?
There is no single answer. A Qualifying Free Zone Person can obtain a 0% rate on qualifying income, but the regime comes with strict activity, substance, transfer pricing, audit and de minimis conditions. A mainland company generally has a simpler rate structure and may have access to reliefs that are unavailable to a Qualifying Free Zone Person.
The correct comparison should therefore be based on the business model rather than the licence label. Customer location, related-party transactions, activities, expected revenue, operating substance, audit costs and future expansion can all affect the practical Corporate Tax position.
Common Mainland vs Free Zone Corporate Tax Mistakes
Many Corporate Tax errors arise because a business assumes that its licence location determines its tax rate. The most common issues are usually caused by applying a simplified “mainland 9%, Free Zone 0%” approach without checking the detailed rules.
- Assuming every Free Zone company automatically qualifies for 0% Corporate Tax.
- Treating all revenue from overseas customers as qualifying income without checking the activity rules.
- Failing to assess mainland or other non-Free Zone customer income when applying the de minimis test.
- Applying the AED 375,000 0% threshold to non-qualifying income of a Qualifying Free Zone Person.
- Failing to prepare audited financial statements where Qualifying Free Zone Person status is being claimed.
- Missing transfer pricing requirements for transactions with related parties or connected persons.
- Assuming 0% tax means no Corporate Tax return is required.
How Can Beaufort Associates Help?
Beaufort Associates can review whether a business falls under the standard mainland rules or the Free Zone regime, assess Qualifying Free Zone Person conditions, review qualifying and non-qualifying income, identify Corporate Tax adjustments and prepare the Corporate Tax return for management approval and filing.
For Free Zone businesses, the review can include customer and activity mapping, de minimis calculations, transfer pricing considerations, audited financial statement requirements and the tax treatment of mainland, Free Zone and overseas income. The exact scope depends on the business structure and transactions.
Frequently Asked Questions
Do Free Zone companies pay 0% Corporate Tax in the UAE?
Not automatically. A Free Zone Person must meet the conditions to be a Qualifying Free Zone Person. The 0% rate then applies to qualifying income, while taxable income that is not qualifying income is generally taxed at 9%.
Do mainland companies always pay 9% Corporate Tax?
No. Under the standard regime, taxable income up to AED 375,000 is generally subject to 0%, while taxable income above AED 375,000 is subject to 9%. Reliefs, exemptions and tax credits can also affect the final liability where applicable.
Can a Free Zone company have mainland customers?
Yes. However, income from mainland customers must be reviewed under the Free Zone Corporate Tax rules. For a Qualifying Free Zone Person, income from non-Free Zone customers generally needs to arise from a qualifying activity and not an excluded activity to be treated as qualifying income.
Does a Free Zone company need an audit for Corporate Tax?
A Qualifying Free Zone Person (a Free Zone business that meets the conditions for the special Corporate Tax regime) is required to prepare and maintain audited financial statements under Ministerial Decision No. 84 of 2025. For Corporate Tax purposes, certain other businesses must also prepare and maintain audited financial statements, including a Taxable Person (for example, a company carrying on a taxable business) that is not a Tax Group and has Revenue exceeding AED 50 million in the relevant Tax Period (the financial period for which Corporate Tax is calculated and filed).
Do Free Zone companies still have to file a Corporate Tax return if their qualifying income is taxed at 0%?
Yes. A 0% Corporate Tax rate on qualifying income does not by itself remove the Corporate Tax return filing obligation.
Can Beaufort Associates review whether my Free Zone company qualifies for 0% Corporate Tax?
Yes. Beaufort Associates can review the company’s activities, income streams, customer profile, substance, de minimis position, transfer pricing requirements and other relevant conditions to assess the applicable Corporate Tax treatment.
