Introduction
For several years, free zone businesses in the UAE treated Economic Substance Regulations (ESR) as the annual ritual that proved they were real. Notifications, reports and the language of Core Income-Generating Activities became part of the compliance calendar. Then, with Cabinet Decision No. 98 of 2024, the obligation largely vanished. ESR no longer applies to financial years starting on or after 1 January 2023, the related penalties for those later periods were lifted, and many founders quietly concluded that substance was now someone else's problem. That conclusion is wrong, and in 2026 it is an expensive one.
Substance did not disappear when ESR was repealed. It was absorbed into the corporate tax law as the adequate-substance condition that a Qualifying Free Zone Person (QFZP) must satisfy to apply the 0% rate. The same vocabulary, Core Income-Generating Activities, adequate assets, qualified employees and operating expenditure, now sits inside Federal Decree-Law No. 47 of 2022 and its supporting decisions, tested through the corporate tax return rather than a separate ESR filing. This advisory note explains what changed, what stayed the same, and what adequate substance actually requires in practice. It is written for founders, finance leaders and licence holders operating from UAE free zones who want to keep their 0% position defensible rather than assume it.
What Cabinet Decision No. 98 of 2024 Actually Did
The repeal was real, but narrower than the headlines suggested. It removed a reporting regime; it did not remove the underlying expectation that a business has genuine presence where it claims to earn its income.
- ESR ended for financial years starting on or after 1 January 2023. There is no ESR notification and no ESR report to file for those years.
- Penalties for those later periods were abolished, and amounts already paid for non-compliance in periods after 31 December 2022 were, in principle, to be refunded by the Federal Tax Authority (FTA).
- ESR still applied for financial years 2019 to 2022. Those obligations were not erased and the records remain relevant.
- Substance moved, it did not vanish. The corporate tax law carries its own substance requirement for free zone entities seeking the 0% rate.
Why ESR became redundant rather than unnecessary
ESR was introduced to align the UAE with international standards on real economic activity. When the federal corporate tax regime arrived with its own substance requirement built into the QFZP conditions, two parallel regimes were testing broadly the same thing. Cabinet Decision No. 98 of 2024 resolved the duplication by retiring ESR for periods that fall under corporate tax. The policy goal, that profits should be earned where the activity actually happens, is unchanged. Only the mechanism changed.
ESR repealed does not mean substance repealed
Read the repeal precisely. Cabinet Decision No. 98 of 2024 ended ESR filings for financial years starting on or after 1 January 2023. It did not remove the requirement to have real people, premises and activity behind your income. For free zone entities, that requirement now lives in the corporate tax adequate-substance condition, and failing it costs the 0% rate.
You Still Need Your Old ESR Records
A repeal is not an instruction to shred files. ESR applied for financial years from 1 January 2019 to 31 December 2022, and those years can still be examined.
- Retain ESR notifications and reports for the 2019 to 2022 periods, generally for around six years.
- Keep the underlying evidence that supported those filings, including board minutes, payroll, leases and operational records.
- Treat that evidence as a head start. The same material supports your corporate tax substance position, so the documentation work is not wasted.
Note: The repeal applies to financial years starting on or after 1 January 2023. If your business had reportable relevant activities in earlier years and did not file, that historic exposure is not cured by the repeal. Where there is doubt, take advice before assuming the slate is clean.
Substance Now Lives Inside the QFZP Conditions
To apply the 0% rate, a free zone person must be a Qualifying Free Zone Person, which means meeting a set of cumulative conditions for each tax period. Adequate substance is one of them, and it is the condition the old ESR most directly became.
The full QFZP conditions, in outline, are:
- Maintain adequate substance in a free zone relative to the activities carried on.
- Derive Qualifying Income as defined in the corporate tax decisions.
- Pass the de minimis test on non-qualifying revenue.
- Not elect to be taxed under the standard 9% regime.
- Comply with arm's-length transfer pricing and prepare audited financial statements.
This note focuses on the first condition. The wider mechanics of Qualifying Income and the de minimis test are covered in our companion piece on the free zone 0% rate and the de minimis test. What matters here is that substance is no longer a separate ESR exercise; it is part of the price of admission to the 0% rate, tested every period.
Crucially, QFZP status, including the substance condition, is tested for each tax period. A structure that was adequately staffed in one year but hollowed out the next can lose 0% in the second year. Substance is a continuous operating reality, not a one-time setup task.
The Three Pillars of Adequate Substance
Adequate substance for a QFZP rests on three connected requirements. All must be present, sized to the activity that generates the income.
1. Core Income-Generating Activities in the free zone
The entity must carry out its Core Income-Generating Activities (CIGAs) in a free zone or a Designated Zone. CIGAs are the significant activities that actually produce the income, not the incidental support around them.
- Key commercial decisions taken by people present in the UAE
- Execution of transactions and the substantive operational work behind the revenue
- Management of the risks associated with the income-generating activity
What counts as a CIGA depends on the business. For a trading company it is sourcing, negotiating and executing trades. For a fund manager it is investment decision-making and portfolio management. For a holding company it is the genuine exercise of ownership functions. The common thread is that the activity that earns the money happens in the zone.
2. Adequate assets in the zone
The QFZP must maintain assets appropriate to the scale and nature of the business, located in the free zone.
- Premises suitable for the activity, whether an office, a warehouse or a facility
- Equipment and infrastructure proportionate to what the business actually does
- Assets that match the income, so a substantial revenue line is not run from a desk that could not plausibly support it
3. Qualified employees and operating expenditure
The QFZP must employ an adequate number of qualified full-time employees in the free zone and incur an adequate level of operating expenditure there.
- People with the right skills to perform the CIGAs, employed and genuinely working in the UAE
- Full-time presence proportionate to the activity, not a single nominal name on a register
- Operating spend in the zone that is consistent with the scale of the income claimed
Build the substance file as you operate
Substance is judged on facts, not on the licence wording. Keep contemporaneous evidence: employment contracts and payroll, the lease and utility records for your premises, organisational charts, and minutes showing where decisions are taken. A file assembled in real time is far more persuasive than a narrative written after an FTA query lands.
How Much Is "Adequate"? There Is No Magic Number
The most common question is the hardest to answer with a single figure, because the law deliberately avoids one. There is no statutory minimum headcount, no fixed square-footage and no prescribed spend. Adequacy is assessed case by case, relative to the nature and scale of the income being generated.
The practical test is proportionality. A lean advisory firm earning modest fees and a large commodity trader moving significant volumes will look completely different, yet both can be adequate for their respective activities. The question an examiner asks is simple: could the people, premises, assets and expenditure actually present in the zone plausibly produce the income being claimed at 0%? If the honest answer is no, the structure is at risk.
| Business profile | What adequate tends to look like |
|---|---|
| Lean advisory or services firm | A genuine office, the principals and key staff working in the UAE, and the decisions and delivery happening locally |
| Trading and distribution company | Premises and storage appropriate to the goods, staff handling sourcing and execution, and operating spend that matches turnover |
| Fund or asset manager | Qualified investment professionals present in the UAE making and managing investment decisions |
| Holding company | Sufficient presence to genuinely hold and oversee the assets, which for passive holding may be modest but must be real |
Note: The figures and expectations vary by activity and by zone. Some free zones publish their own guidance on minimum facilities for particular licence types. Confirm current expectations with your zone authority and a tax adviser rather than relying on a rule of thumb.
Outsourcing CIGAs: What Is and Is Not Allowed
Few free zone businesses do everything in-house, so the outsourcing rules matter. The corporate tax framework permits outsourcing, but on conditions designed to keep the substance genuinely in the UAE.
The general rule
A QFZP may outsource its CIGAs to a related party or a third party, provided that party is located in a free zone or a Designated Zone and the QFZP retains adequate supervision and control over the outsourced activity. The key constraints are location and oversight:
- Location: the outsourced CIGAs are performed in a free zone or a Designated Zone, not offshore.
- Supervision: the QFZP genuinely directs and monitors the work; it cannot simply hand the activity away and collect the income.
Outsourcing the core activity entirely outside the UAE, or to a provider over which the QFZP exercises no real control, does not satisfy the substance test. The activity, and the supervision of it, must stay anchored in the zone.
The broader rule for qualifying intellectual property
For qualifying intellectual property (IP) income, the outsourcing rules are more flexible. The relevant research and development activity can be outsourced to other persons in the UAE, or to non-related parties outside the UAE, with adequate supervision. This reflects the way IP and R&D work is genuinely conducted across borders. Qualifying IP income is also subject to the modified nexus approach, which ties the 0% benefit to the proportion of income linked to the entity's own qualifying R&D expenditure, so the substance and the income calculation work together.
Supervision is the load-bearing word
Outsourcing is allowed, but only with adequate supervision and control. A contract that transfers the activity to a provider with no oversight from the QFZP does not create substance; it removes it. Keep evidence that your team directs, reviews and signs off on the outsourced work.
The Cost of Getting It Wrong
Under the old ESR, a substance failure attracted administrative penalties. Under corporate tax, the consequence is structural and far larger: it goes to the rate on your entire income.
Loss of the 0% rate
If a free zone person fails the adequate-substance condition, it ceases to be a QFZP. The 9% corporate tax rate then applies to its taxable income for that tax period and, in principle, for the following four tax periods. A single year's failure can therefore cascade across five years of returns. There is no partial credit: failing the condition does not mean a slightly higher rate on a slice of income; it means the standard rate on the lot.
Why paper-only structures are exposed in 2026
The repeal of ESR created a dangerous illusion that substance no longer matters. In reality, the corporate tax return now asks free zone entities to stand behind their 0% position, and the FTA can examine whether the substance is real. A letterbox company with a licence, a registered address and no genuine activity in the zone is precisely the structure the regime is designed to exclude. The same hollow structure that was an ESR problem before 2023 is now a corporate tax problem with a steeper price.
Knock-on effects
A substance failure rarely stays contained to the tax return:
- Audited accounts must still support the position; weak substance often shows up in the financials.
- Transfer pricing scrutiny tends to follow, since profit booked in a low-substance entity invites challenge.
- Banking and licence renewals increasingly probe genuine activity, so a thin structure can surface in more than one place.
Is your free zone substance strong enough to defend the 0% rate?
AURNE helps free zone businesses assess CIGAs, right-size people and premises, document substance properly and align the corporate tax position with the licence and the operating reality. Replace the assumption with evidence before an FTA query does.
What This Means by Emirate and Zone
The substance rules are federal, so they apply consistently across the UAE. What differs is the practical setup: the type of premises available, the cost base, and the kinds of activity each zone is built around. The right zone is the one where your genuine activity naturally sits.
Dubai
Dubai's free zones cover almost every sector, which makes matching the zone to the activity straightforward. DMCC suits commodities and trading where storage and execution presence support the CIGAs. DIFC is the financial and professional services hub where regulated activity and decision-making presence are expected. IFZA is a flexible, cost-efficient base for services and SMEs that still need genuine staffing and premises to support their income.
Abu Dhabi
Abu Dhabi's free zones, led by ADGM, are oriented toward financial services, asset management and holding structures. For fund and asset managers, substance means qualified investment professionals genuinely present and making decisions in the emirate, not a name on a register.
Ras Al Khaimah
Ras Al Khaimah's free zones, notably RAKEZ, are a competitive base for industrial, manufacturing and trading businesses. For these, adequate assets, the warehouse or facility, the equipment and the operational staff, are the visible heart of the substance position.
| Activity type | Substance emphasis | Illustrative zones |
|---|---|---|
| Commodities and trading | Storage, execution staff, operating spend | DMCC, JAFZA, RAKEZ |
| Financial and professional services | Qualified people, local decision-making | DIFC, ADGM |
| Services and SMEs | Genuine office and staffing proportionate to fees | IFZA, Meydan |
| Industrial and manufacturing | Facilities, equipment, operational workforce | RAKEZ, KIZAD |
Note: Zone offerings, facilities and pricing change frequently. Use the categories above as a starting point and confirm current packages, premises options and any activity-specific facility expectations directly with the relevant free zone authority.
Building Substance From the Start: A Practical Sequence
Substance is far cheaper to build correctly at setup than to retrofit after a query. For businesses forming now, the sequence below keeps the licence, the activity and the substance aligned.
- Define the CIGAs first. Identify exactly which activities generate the income, then design the team and premises around performing them in the zone.
- Choose the zone for the activity, not the price alone. A cheap licence in a zone that does not fit the activity creates a mismatch that undermines substance. Our company formation in Dubai and trade licence assistance services are built around getting this fit right.
- Right-size people and premises. Hire qualified full-time staff for the CIGAs and take premises proportionate to the activity, not the smallest desk available.
- Document outsourcing properly. Where you outsource CIGAs, keep the activity in a free zone or a Designated Zone and retain written evidence of your supervision and control.
- Maintain the substance file continuously. Update payroll, leases, decision records and organisational charts as the business evolves, so the evidence is always current.
- Reassess each tax period. Confirm before each filing that the substance still supports the income claimed at 0%.
For groups operating across multiple jurisdictions, the same logic applies internationally. Where activity genuinely spans borders, our worldwide company formation and structuring support helps ensure substance sits where the income is booked, not just where it is convenient.
Match the structure to the story you can prove
The strongest position is one where the licence, the staffing, the premises and the corporate tax return all tell the same story. Before adding an entity or a revenue line to a free zone company, ask whether you can genuinely perform and supervise the activity in the zone. If you cannot, the 0% rate on that income is not safe.
Common Misconceptions to Retire in 2026
- "ESR was repealed, so substance no longer matters." The reporting regime ended; the substance requirement moved into corporate tax. The expectation is, if anything, more consequential now.
- "There is a minimum headcount we can hit and be safe." There is no fixed number. Adequacy is proportional to the activity and income, judged on the facts.
- "We can run everything from abroad and keep the licence here." CIGAs must be performed in a free zone or a Designated Zone, with any outsourcing kept in such a zone and genuinely supervised.
- "A 0% rate means we can keep the structure thin." A thin structure is exactly what the regime excludes. Failing substance applies 9% to all income for the period and the next four.
- "Old ESR files are irrelevant now." They support both your historic 2019 to 2022 position and your current corporate tax substance, and should be retained.
Key Takeaway
ESR was repealed, but substance was promoted, not removed. Adequate substance is now a condition of the 0% free zone rate, requiring real CIGAs, assets, qualified staff and operating expenditure in the zone. Fail it and 9% applies to all income for the period and the following four, which makes paper-only structures a live 2026 risk.
Conclusion
The end of Economic Substance Regulations for financial years from 2023 onward removed a filing, not a principle. The UAE still expects profits to be earned where the activity genuinely happens, and for free zone businesses that expectation now sits inside the corporate tax law as the QFZP adequate-substance condition. The familiar vocabulary of Core Income-Generating Activities, adequate assets, qualified employees and operating expenditure carried straight across, which is why the documentation you built for ESR remains valuable and why your old records should be kept rather than discarded.
The stakes, however, are higher than they were under ESR. A substance failure no longer means a contained administrative penalty; it means losing Qualifying Free Zone Person status and applying 9% corporate tax to the entire income base for the period and, in principle, for the following four. The businesses most exposed are the ones that mistook the repeal for a relaxation and left a licence in a zone with no genuine people, premises or activity behind it. In 2026 that gap is precisely what a corporate tax review is built to find.
This is where careful structuring and honest documentation pay for themselves. AURNE works with free zone businesses to define their CIGAs, right-size their people and premises, document substance as they operate and align the licence, the activity and the corporate tax return into a single consistent story. The figures and facility expectations vary by activity and by zone and they change, so confirm current requirements with your free zone authority and a tax adviser. The entities that treat substance as an operating reality, not a repealed formality, are the ones whose 0% rate will still stand when it is tested.
