UAE Corporate Tax: What It Means for Free Zone Companies in 2026

The headline: 9% CT applies from June 2023

UAE Corporate Tax at 9% applies to businesses with taxable income above AED 375,000. Income below that threshold is taxed at 0%.

This applies to mainland and free zone companies alike, unless the free zone entity qualifies for Qualifying Free Zone Person (QFZP) status, which preserves the 0% rate on qualifying income. The UAE has no personal income tax, so CT is the primary direct tax founders need to plan for.

Who needs to register for Corporate Tax

All UAE businesses (mainland and free zone) with annual revenue above AED 1 million must register for Corporate Tax with the Federal Tax Authority (FTA), even if their taxable income falls below the AED 375,000 threshold.

Registration is done through the EmaraTax portal. Failure to register by the deadline carries penalties starting at AED 10,000. Free zone companies seeking QFZP status must register and file returns to claim the 0% rate. The exemption is not automatic.

Qualifying Free Zone Person criteria

To maintain QFZP status and 0% CT on qualifying income, a free zone company must meet four conditions:

1. Maintain adequate substance in the free zone: real operations, a physical presence (office or flexi-desk), and qualified employees proportional to the business activity.
2. Derive qualifying income: transactions with other free zone persons or with customers outside the UAE (not mainland UAE transactions).
3. Not elect out of the free zone tax regime.
4. Prepare audited financial statements and comply with transfer pricing documentation rules for any related-party transactions.

Qualifying vs non-qualifying income

The 5% de minimis rule

The most common pitfall is deriving non-qualifying income from mainland UAE customers. If more than 5% of your total revenue (or AED 5 million, whichever is lower) comes from non-qualifying sources, you lose QFZP status for that entire tax period and pay 9% on all income.

This catches many free zone companies by surprise, especially those providing services to Dubai mainland clients. The 5% threshold is calculated on a per-tax-period basis, so a single large mainland contract can trigger full taxation for the year.

One large mainland contract can flip your entire year to 9% CT if it pushes non-qualifying income above the 5% threshold.

Substance requirements explained

The FTA evaluates substance based on whether the free zone entity has adequate employees (or outsourced qualified personnel), adequate assets, and conducts its core income-generating activities within the free zone.

A shell company with no employees and no real operations will not satisfy substance requirements, even if all revenue is from non-UAE customers. The level of substance required scales with the size and complexity of the business.

A solo consultant with a flexi-desk and genuine client work may satisfy substance requirements; a holding company with AED 50 million in assets and no local staff likely will not.

Transfer pricing and related-party transactions

Free zone companies transacting with related parties (parent companies, subsidiaries, entities under common ownership) must comply with UAE transfer pricing rules. This means maintaining a transfer pricing policy, preparing a local file and (if applicable) a master file, and ensuring that related-party transactions are priced at arm's length. The FTA has adopted OECD transfer pricing guidelines. Non-compliance can result in adjustments that increase taxable income and trigger penalties.

Audited financial statements

All QFZP entities must prepare audited financial statements, regardless of size. This is a departure from the previous UAE norm where many free zone companies operated with minimal bookkeeping. The audit must be conducted by a UAE-registered auditor. Financial statements should comply with IFRS (International Financial Reporting Standards) or IFRS for SMEs.

What to do now

Review your revenue mix. If you have mainland UAE clients, assess whether the volume triggers the 5% non-qualifying threshold. Consider whether your business model is better served by a mainland licence instead of (or alongside) your free zone entity. Ensure your bookkeeping is accurate from day one, because the FTA requires audited financials from QFZP entities. Register for CT on the EmaraTax portal if you have not already done so.
