A UAE Free Zone company can have the right licence yet face Corporate Tax questions when revenue records do not support 0% treatment. A Free Zone Qualifying Income Audit asks whether the business can prove why each revenue stream qualifies under UAE Corporate Tax rules. The answer can depend on the customer, actual activity, contract terms, invoice, accounting records, and supporting evidence.
Companies can also face problems when revenue streams are mixed, the de minimis threshold is miscalculated, or related-party records are weak. The tax position should be tested before filing. Audit Services UAE helps businesses review these records before a formal audit or Corporate Tax filing. The focus is the evidence behind each revenue figure.
What Is Qualifying Income Under UAE Free Zone Corporate Tax?
Qualifying Income falls within the categories and conditions set for a Qualifying Free Zone Person. It can include income from transactions with other Free Zone Persons in specified cases, income from Qualifying Activities, qualifying intellectual property income, and certain other income where de minimis conditions are met.
A QFZP must also meet requirements such as adequate substance and transfer pricing compliance. Income that does not meet the relevant conditions can be taxed at 9%.
The Audit Test: How Auditors Check Whether Income Qualifies
An auditor may trace a revenue balance to the underlying transaction instead of accepting the general ledger description alone. The review may cover:
- Customer status and location, including whether the customer is another Free Zone Person and the required conditions.
- Contract terms and actual activity, checking that recorded revenue matches the work actually performed.
- Invoice descriptions and accounting codes, checking that the revenue account reflects the transaction and tax treatment.
- Delivery, customs or service records supporting goods movement or service performance.
- Bank receipts and ledger entries, allowing the auditor to trace reported revenue through accounting records.
- Corporate Tax schedules, including qualifying and non-qualifying revenue classifications and de minimis workings.
Which Activities Can Generate Qualifying Income?
The qualifying activity rules cover several types of business activity, but each has its own conditions.
- Manufacturing and processing can qualify where the company performs the required functions and keeps supporting records.
- Holding shares and securities for investment can qualify when the applicable conditions are met.
- Certain fund, wealth, investment management, reinsurance, shipping and aircraft activities can qualify when their conditions are met.
- Headquarters and treasury or financing services may qualify under the current rules.
- Qualifying commodity trading should be tested against commodity definitions, pricing requirements and recognised price reporting rules.
- Distribution in or from a Designated Zone can qualify when location, importation and customer conditions are met.
What Counts as Excluded or Non-Qualifying Income?
A Free Zone company may have revenue that falls outside the qualifying categories. Such revenue should be identified early because it can affect the de minimis calculation and QFZP status.
- Certain natural-person transactions are excluded, subject to specific exceptions for listed activities.
- Certain banking, finance, leasing and insurance activities can fall within the excluded activity rules.
- Certain immovable property income may not receive 0% treatment and should be assessed separately.
- Income from non-qualifying activities may be non-qualifying when the customer is outside a Free Zone.
- Excluded revenue should not be placed in a qualifying account simply because the company is in a Free Zone.
- Mixed revenue streams should be separated so the de minimis calculation uses the correct figures.
The De Minimis Test: Where Many QFZPs Get Into Trouble
The de minimis rule allows a limited amount of non-qualifying revenue, subject to the prescribed threshold. The limit is the lower of 5% of total revenue or AED 5 million.
- The company must identify non-qualifying revenue before applying the percentage test.
- Total revenue must be calculated using the applicable rules rather than an unchecked income-statement figure.
- The threshold is the lower of 5% of total revenue and AED 5 million.
- Certain revenue categories may require adjustments under the rules.
- Exceeding the limit can affect QFZP status for the relevant and following four Tax Periods.
Why Revenue Classifications Fail During an Audit
Revenue classification can look simple in accounting software but become difficult when an auditor asks for the evidence behind each balance. One sales account may contain Free Zone customers, mainland customers, and overseas customers, while invoices may use the same description for different activities.
That makes it harder to show why one transaction qualifies and another does not. Problems also arise when related-party income has no clear agreement, distribution sales lack goods-movement records, or non-qualifying revenue is left out of the de minimis calculation. A review should compare the contract, customer details, invoice, service evidence, ledger entry, and tax treatment. If these records conflict, the classification may be questioned.
When revenue records contain unexplained differences or unusual transactions, businesses may need a closer review of the underlying evidence. Forensic Audit Services can help examine financial records, transaction trails, and supporting documents when a deeper investigation is needed.
Transfer Pricing and Related-Party Income
Related-party transactions need clear support because transfer pricing compliance is a QFZP condition. Keep:
- Written intercompany agreements describing services, responsibilities and payment terms.
- A clear pricing basis showing how charges were determined under transfer pricing rules.
- Functional information showing the people, assets and functions involved in the transaction.
- Transfer pricing analysis supporting the Corporate Tax treatment and disclosures.
- Reconciliations between agreements, invoices, ledger entries and payments.
Substance: Can the Company Prove It Performed the Activity in the UAE?
Adequate substance is more than a registered Free Zone address. Records should support the functions performed there.
- Employees and roles should link to business activities and be supported by payroll records.
- Office or operating arrangements should support the actual business activity.
- Operating expenditure, systems and records should support functions performed during the Tax Period.
- Management and activity records should show that the company is actively carrying out business.
- Outsourced functions should be documented, supervised and consistent with substance rules.
What Changed Under Ministerial Decision No. 229 of 2025?
Ministerial Decision No. 229 of 2025 replaced MD 265 of 2023 and applies retrospectively from 1 June 2023. The FTA lists it in current Corporate Tax legislation.
- The qualifying commodities definition was expanded to include industrial chemicals, certain associated by-products and environmental commodities.
- Treasury and financing services were updated to cover qualifying services to related parties or for the QFZP’s own account.
- Distribution of goods or materials in or from a Designated Zone received further clarification around location, importation and customer conditions.
- Companies relying on older activity lists should review classifications against MD 229 and current guidance.
- Businesses that filed earlier returns should consider the retrospective effect when reviewing their qualifying activity position.
The 2026 Audit Requirement for Free Zone Distribution Businesses
FTA Decision No. 6 of 2026 introduced additional compliance procedures for QFZPs carrying out qualifying distribution activities in or from a Designated Zone.
- Affected QFZPs must obtain an agreed-upon procedures report from an independent external auditor for the relevant distribution activity.
- The report must follow ISRS 4400 and address the specific procedures set by the Federal Tax Authority.
- Customer reseller status may be tested through trade licences, customer confirmations, sales agreements and transaction records.
- Designated Zone importation may be tested through import documents, zone-status evidence, inventory records and goods movement records.
- The AUP report must be submitted to the FTA within 30 days after the Corporate Tax return filing deadline, unless another date is set by the FTA.
For Free Zone businesses that require audited financial statements alongside their QFZP compliance work, External Audit Services can provide independent examination of financial statements, revenue balances and supporting accounting records. The separate 2026 agreed-upon procedures requirement for applicable distribution activities should still be addressed according to the specific FTA procedures and ISRS 4400 requirements.
Documents Auditors May Ask For
Typical records include:
- Sales invoices, credit notes, customer ledgers and revenue schedules that allow material revenue streams to be traced into the financial statements.
- Trade licences, customer details, Free Zone registration evidence and other records supporting customer status and transaction conditions.
- Contracts, purchase orders, delivery records, customs documents and service reports showing what the company agreed to provide and actually delivered.
- Bank statements, accounting ledgers, reconciliations and supporting schedules connecting recorded revenue to receipts and reported figures.
- Corporate Tax calculations, de minimis workings, transfer pricing files, activity classifications and other schedules supporting the company’s QFZP position.
For businesses dealing with physical goods, inventory records may also need to match the quantities and transactions reported in the accounts. Stock Count Services can help verify physical stock records and support the accounting evidence used during an audit.
Seven Common Reasons Free Zone Companies Fail the Qualifying Income Test
The qualifying income test can fail because of small gaps in classification, records, or supporting evidence. These are some of the common issues auditors may find when reviewing a Free Zone company’s Corporate Tax position.
1. Treating Every Free Zone Sale as Qualifying
A Free Zone customer does not automatically make every transaction qualifying. The activity and other conditions still need to be checked.
2. Relying Only on the Trade Licence
A trade licence shows permitted activities, but it does not prove what the company actually performed in a particular transaction.
3. Mixing Different Revenue Streams
Combining qualifying services, excluded activities and other revenue in one account can make the tax treatment difficult to support.
4. Miscalculating the De Minimis Threshold
An error in total revenue or non-qualifying revenue can change the threshold and affect the company’s QFZP status.
5. Weak Related-Party Records
Intercompany invoices without agreements, pricing support and transaction evidence can raise questions during a review.
6. Missing Activity Evidence
A company may record qualifying income correctly but lack contracts, service evidence or other documents.
7. Incorrect Customer Classification
Income may be treated as qualifying without checking the customer’s status and applicable conditions. Customer records should support the classification used for Corporate Tax purposes.
What Happens If a Company Loses QFZP Status?
If a Free Zone Person fails a required QFZP condition, it can lose QFZP status from the beginning of the relevant Tax Period and for the following four Tax Periods. The business then falls under the standard Corporate Tax treatment during that period. This can create a material tax cost. Management may need to revisit revenue classifications, Corporate Tax calculations, and supporting schedules.
Where Audit Services UAE Adds Value Before QFZP Filing
Audit Services UAE can help businesses trace qualifying and non-qualifying revenue classifications back to contracts, customer records, invoices, accounting entries, receipts and Corporate Tax schedules before the filing position is finalised.
The readiness review should also check whether de minimis workings, related-party documentation, substance evidence and activity classifications tell the same story across the accounting records and tax file. For distribution businesses affected by the separate 2026 AUP requirement, the supporting documents should also be organised around the specific procedures that the independent auditor will need to perform.
Conclusion
A Free Zone licence does not make all business income subject to the 0% Corporate Tax rate. A proper Free Zone Qualifying Income Audit looks at the customer, activity, contract, invoice, accounting entry and supporting evidence together. The de minimis calculation, related-party transactions, substance requirements and current regulatory changes all deserve attention before filing.
Audit Services UAE can help businesses review these areas and identify records that need attention. For distribution companies, the 2026 AUP requirements add another layer of documentation. A clear audit file gives management a stronger basis for its QFZP position and supports a Free Zone Qualifying Income Audit.
