For four years the UAE tested business substance through the Economic Substance Regulations (ESR): a separate notification, a separate report and a separate penalty regime. Since Corporate Tax started for tax periods beginning on or after 1 June 2023, that role has passed to the tax system itself. ESR filings ended for financial years ending after 31 December 2022, and substance is now tested inside several Corporate Tax rules: the conditions for Qualifying Free Zone Persons, the arm's length principle and transfer pricing documentation, the Domestic Minimum Top-up Tax for large multinational groups, and the residence test for foreign companies managed from the UAE. This guide compares what ESR required with what Corporate Tax requires now, so that consultants and finance teams can see which old evidence still has a use and where the new tests go further.
What ESR asked businesses to prove
Under Cabinet Resolution No. 57 of 2020, a licensee carrying on a Relevant Activity, such as banking, insurance, fund management, headquarters, holding company, intellectual property or distribution and service centre business, had to meet the Economic Substance Test. Article 6 required the licensee to conduct its core income-generating activities in the UAE, to have the activity directed and managed in the UAE, and to have an adequate number of qualified full-time employees, adequate operating expenditure and adequate physical assets in the UAE, having regard to the level of the activity. For the directed and managed condition, the board had to meet in the UAE at an adequate frequency with a quorum physically present and the minutes kept in the UAE.
ESR was a reporting regime. It did not change how much tax a business paid. Its sanctions were administrative penalties, exchange of information with foreign authorities, and possible action against the trade licence. The Ministry of Finance announced in 2024 that, following Cabinet Decision No. 98 of 2024, notifications and reports are no longer required for financial years ending after 31 December 2022. For the duties that remain for 2019 to 2022, see our guide on what happened to the UAE Economic Substance Regulations.
ESR and Corporate Tax side by side
The table below compares the ESR test with the Corporate Tax rules that now carry a substance element. The key difference is that Corporate Tax ties substance to the tax rate or the tax base, so a failure costs tax rather than only a penalty.
| Point | ESR (financial years 2019 to 2022) | Corporate Tax (tax periods from 1 June 2023) |
|---|---|---|
| Legal basis | Cabinet Resolution 57 of 2020, amended by Cabinet Decision 98 of 2024 | Federal Decree-Law No. 47 of 2022 and its implementing decisions |
| Who is in scope | Licensees carrying on one of nine Relevant Activities | Free zone companies claiming the 0% rate, related party transactions, large multinational groups, foreign companies managed in the UAE |
| Substance test | Core income-generating activities, directed and managed in the UAE, adequate staff, expenditure and assets | Adequate substance in a free zone for Qualifying Free Zone Persons; functions, assets and risks for transfer pricing; payroll and tangible assets in the Pillar Two exclusion |
| Filing | Annual notification and Economic Substance Report to the regulatory authority | Corporate Tax return to the FTA, with transfer pricing disclosures and, for in-scope groups, Top-up Tax filings |
| Consequence of failure | Fixed administrative penalties, exchange of information, licence action | Loss of the 0% rate, transfer pricing adjustments, Top-up Tax, plus tax procedure penalties |
Free zone companies: the adequate substance condition
The closest successor to ESR is the Qualifying Free Zone Person (QFZP) regime. Under Article 3(2) of the Corporate Tax Law, a QFZP pays 0% on Qualifying Income and 9% on taxable income that is not Qualifying Income. Article 18(1) lists the conditions: the free zone company must maintain adequate substance in the State, derive Qualifying Income, not have elected to be subject to the standard rates, comply with the arm's length principle and transfer pricing documentation rules, and meet any other conditions set by the Minister.
Article 8 of Cabinet Decision No. 100 of 2023 defines adequate substance. The company must undertake its core income-generating activities in a free zone, or in a designated zone where the activity requires it, and have adequate assets, an adequate number of qualified full-time employees and adequate operating expenditure there for each activity. Core income-generating activities can be outsourced to another person in a free zone or designated zone if the company adequately supervises them. For Qualifying Intellectual Property the outsourcing can also be to any other person in the State or to a non-related person outside the State.
Compared with ESR, three points stand out:
- Location is narrower. ESR asked for substance in the UAE. The QFZP test asks for substance in the free zone, or in a designated zone for distribution, as the FTA's Free Zone Persons guide explains.
- The test applies throughout the tax period. A QFZP that fails a condition at any time during a tax period ceases to be a QFZP from the beginning of that period and for the following four tax periods (Ministerial Decision No. 229 of 2025, Article 5).
- Other conditions sit next to substance. Non-qualifying revenue must stay within the de minimis limit of 5% of total revenue or AED 5,000,000, whichever is lower, and the company must prepare audited financial statements.
More detail on qualifying activities and the de minimis rule is in our guide to free zone Corporate Tax treatment.
Large groups: the Domestic Minimum Top-up Tax
Article 3(3) of the Corporate Tax Law, added by Federal Decree-Law No. 60 of 2023, directed the Cabinet to set rules so that multinational enterprises in scope pay an effective tax rate of 15%. Cabinet Decision No. 142 of 2024 introduced the UAE Domestic Minimum Top-up Tax for fiscal years beginning on or after 1 January 2025. It applies to constituent entities of multinational groups with annual revenue of EUR 750 million or more in the consolidated financial statements of the ultimate parent entity in at least two of the four preceding fiscal years. The Minimum Rate is 15%.
Substance enters this regime through the Substance-based Income Exclusion in Article 5.3 of the decision. The UAE net Pillar Two income is reduced by a payroll carve-out and a tangible asset carve-out, based on eligible payroll costs of employees working in the UAE and eligible tangible assets located in the UAE, before the top-up tax is calculated. The more real activity a group has in the UAE, the smaller the excess profit that can be topped up. A filing entity can elect each year not to apply the exclusion.
For a group that once relied on a free zone entity with a thin ESR file, the result can be that profits at 0% under the QFZP rules are still brought up to 15% through the Top-up Tax. The Ministry of Finance has also stated that the UAE is not applying the Income Inclusion Rule at this stage.
Transfer pricing: substance through functions and risks
Article 34 of the Corporate Tax Law requires related party transactions to follow the arm's length principle. In practice, profit should follow the entity that performs the functions, uses the assets and controls the risks. That is a substance question in a different form: an entity with no staff in the UAE should not report profits that depend on decisions made elsewhere.
Documentation rules make this visible. A taxable person must keep a master file and a local file if its revenue is AED 200 million or more in the tax period, or if it is a constituent company of a multinational group with consolidated revenue of AED 3.15 billion or more (Ministerial Decision No. 97 of 2023). The files must be provided within 30 days of an FTA request (Article 55). Compliance with Articles 34 and 55 is also a QFZP condition. Our guides to transfer pricing documentation requirements and related party transactions cover the detail.
Tax residence: where a company is managed
Under Article 11(3)(b) of the Corporate Tax Law, a company incorporated abroad is a UAE resident person if it is effectively managed and controlled in the State. This replaces the ESR question of whether an activity was directed and managed in the UAE with a residence test that brings the whole company into UAE Corporate Tax. Board practice, the location of senior decision makers and the place where strategic decisions are recorded all matter.
The same evidence is used in the other direction. A UAE company that wants to claim benefits under a double tax agreement needs a tax residency certificate from the FTA, and the FTA asks juridical persons for proof of management and control in the UAE where applicable. A treaty can also allocate residence to another country, so groups with directors spread across jurisdictions should review where management actually takes place.
What to check now
- For each free zone entity, map core income-generating activities, staff, assets and expenditure to the free zone, and record any outsourcing and how it is supervised.
- Check that functional descriptions in old ESR reports, transfer pricing files and QFZP analysis are consistent.
- For groups near EUR 750 million in revenue, test the revenue threshold for each relevant year and collect payroll and tangible asset data by location for the Substance-based Income Exclusion.
- For foreign holding or financing companies with UAE directors, review where board meetings take place and where decisions are made.
- Keep Corporate Tax records for seven years after the end of the tax period (Article 56), and keep ESR records for the earlier years for six years from submission.

Frequently asked questions
Did Corporate Tax replace the Economic Substance Regulations?
Not formally, but in effect yes for current years. Cabinet Decision 98 of 2024 ended ESR notifications and reports for financial years ending after 31 December 2022, and the Ministry of Finance linked the change to Corporate Tax. Substance is now tested through Corporate Tax rules such as the QFZP conditions and transfer pricing.
Is the QFZP substance test the same as the old ESR test?
It is similar but not the same. Both look at core income-generating activities, employees, expenditure and assets. The QFZP test requires these in a free zone or designated zone rather than anywhere in the UAE, and failing it removes the 0% rate for the tax period and the following four tax periods.
Which groups are subject to the UAE Domestic Minimum Top-up Tax?
Constituent entities of multinational groups with annual revenue of EUR 750 million or more in the ultimate parent's consolidated financial statements in at least two of the four preceding fiscal years. The tax applies for fiscal years beginning on or after 1 January 2025 under Cabinet Decision 142 of 2024.
Can a foreign company become UAE tax resident because of its directors?
It can. A company incorporated abroad is a UAE resident person for Corporate Tax if it is effectively managed and controlled in the State. Where key management and strategic decisions take place in the UAE, the company may be taxed on its worldwide income in the UAE, subject to any applicable tax treaty.
Can old ESR files help with Corporate Tax?
Yes, as a starting point. Substance mapping, headcount data and board records prepared for ESR can support a QFZP analysis or a transfer pricing functional analysis. They must be updated for the current tax period, because the Corporate Tax tests apply to each period on its own facts.
