How UAE Corporate Tax Affects Free Zone Businesses in 2026

When UAE Corporate Tax was introduced under Federal Decree-Law No. 47 of 2022, many Free Zone businesses assumed the 0% rate applied to them automatically. It does not. The zero rate is conditional, income-specific, and requires active ongoing maintenance. Getting this wrong — even unintentionally — carries significant consequences.

The baseline: every Free Zone entity is a taxable person

Every company registered in a UAE Free Zone — whether in DMCC, JAFZA, DIFC, DAFZA, RAKEZ, SAIF Zone or any of the UAE's 40-plus designated zones — is a taxable person under the CT Law. That means mandatory FTA registration, annual return filing and Corporate Tax obligations. Free Zone registration does not, by itself, create any exemption.

The 0% rate is available only to a Qualifying Free Zone Person (QFZP), and even then it applies only to that company's Qualifying Income. Non-qualifying income earned by a QFZP is taxed at the standard 9% rate. Both streams are reported on a single corporate tax return.

What makes a company a QFZP

To qualify as a QFZP, a Free Zone company must simultaneously satisfy all of the following conditions:

• Be incorporated or registered in a recognised UAE Free Zone — including branches of foreign companies registered in a Free Zone.
• Maintain adequate substance in the Free Zone — this requires qualified, full-time employees physically present in the zone, appropriate physical assets, material operating expenditure and management decisions being taken in the UAE. A registered address or flexi-desk arrangement without supporting operational presence is typically insufficient.
• Derive Qualifying Income — as defined under Cabinet Decision 100 of 2023 and updated by Ministerial Decision 229 of 2025.
• Comply with transfer pricing rules — all related-party transactions must be conducted on arm's length terms with full documentation.
• Maintain audited financial statements — a requirement introduced by Ministerial Decision 84 of 2025 for all QFZPs.
• Not have elected into the standard 9% regime — once elected, this cannot easily be reversed.

The QFZP test is a gate, not a menu. All conditions must hold at once. Failing any single condition strips the company of QFZP status entirely — not just for the income stream in question.

What counts as Qualifying Income

Qualifying Income is income derived from Qualifying Activities as listed under Ministerial Decision 229 of 2025, which replaced the earlier MD 265 of 2023 and applies retroactively from 1 June 2023. The updated list expanded the qualifying side to include chemicals and by-products, carbon credits, renewable energy certificates and a broadened treasury and financing carve-out.

Income from transactions with mainland UAE companies is, in most cases, not Qualifying Income. This is where many Free Zone businesses encounter unexpected tax exposure — particularly trading companies that sell into the mainland or service providers with significant mainland clients.

The de minimis rule

A QFZP is permitted to earn a limited amount of non-qualifying revenue without immediately losing its status. The threshold is the lower of AED 5,000,000 or 5% of total revenue in non-qualifying income within a tax period. Exceeding either limit strips QFZP status for that entire tax period and the following four tax periods, with all taxable income reverting to the standard 9% rate above AED 375,000. The consequences of breaching de minimis are therefore disproportionate to the breach — a small amount of non-qualifying income can trigger a multi-year tax liability.

Cycle 2 returns and increased audit exposure

Cycle 2 corporate tax returns — covering financial years ending 31 December 2025 — are due by 30 September 2026. The FTA issued significant additional guidance during 2025 on how trading income, distribution activities, holding structures and intra-group transactions interact with the QFZP regime. Many Cycle 1 returns were filed with caveats or based on earlier interpretations. Cycle 2 returns are expected to be held to a higher standard, and audit exposure is elevated for any entity that claimed QFZP status in Cycle 1 under positions that no longer hold up under refined guidance.

What Free Zone businesses should do now

• Review your income mix against the current Qualifying Activities list under MD 229 of 2025 — not the earlier 2023 version.
• Assess your substance position honestly. Headcount, physical presence and decision-making location all matter.
• Check your mainland revenue exposure against the de minimis thresholds.
• Ensure audited financial statements are in place — this is now a formal QFZP requirement, not just good practice.
• File a voluntary disclosure through the FTA's EmaraTax portal if you identify a position that needs correcting — before any audit notification is issued, when penalties are lower.
