Continental investors meet the Irish section 110 company from the outside. It appears in a structure chart as a box holding loans, receivables or notes, described as tax neutral, and the investor is asked to subscribe for profit participating notes issued by it. The description is broadly accurate and also incomplete, because neutrality here is not an exemption. It is the result of a computation that gives the company a deduction for what it pays out, and every restriction on that deduction restricts the neutrality.
Those restrictions have grown. The regime was built for securitisation and still works for it, but successive amendments have carved out Irish property, limited deductions to recipients that are actually taxed, and extended the definition of control to reach arrangements that were formally orphaned. An investor coming from the continent is rarely the person who set the vehicle up, and is frequently the person who discovers two years later that a condition was not met.
What a qualifying company actually is
Revenue’s manual on entitlement to section 110 treatment, updated in August 2026 and read here against the section as amended to Finance Act 2025, sets out the conditions in a list worth reading in full rather than in summary. The company must be resident in Ireland. It must acquire, hold or create qualifying assets. It must carry on its business of holding or managing those assets in the State, and carry out no activities other than those ancillary to it. On the first day it acquires qualifying assets it must have 10 million euro of qualifying assets. It must notify Revenue of its intention to be a qualifying company on the prescribed form. And all transactions or arrangements, other than those to which subsection 4 applies, must be entered into by way of a bargain made at arm's length.
Two features of that list are regularly misread. The first is the 10 million euro test. Revenue states that the market value of the qualifying assets must not be less than 10 million euro on the day they are first acquired, held or created, and that there is no requirement that they remain at that level at any other point. A vehicle that amortises down to a fraction of its original size does not fall out of the regime for that reason.
The second is that every other condition must be met throughout the period of operation. The arm’s length condition in particular is continuous, and Revenue’s manual poses it as a practical question: did the qualifying company receive any services or advice that it did not pay for, or did not pay full value for. Structures assembled by a sponsor who provides uncosted support to its own vehicle are exposed on this point long after closing, although the manual adds that the absence of a fee is not always evidence that a transaction was not at arm’s length.
The notification is a deadline rather than a formality. Revenue’s manual on the qualifying company notification requires Form S.110 to reach the authorised officer within eight weeks of the company meeting the 10 million euro condition in paragraph (e) of the definition, and requires Form S.110W from a company that no longer satisfies the criteria or wishes to withdraw its original notification, stating an eight week deadline for the withdrawal case that runs from the date the company wishes to cease to be a qualifying company. Where a securitisation migrates to Ireland, the entitlement manual makes the date of migration both the date on which the 10 million euro test is measured and the date from which that period runs, provided the migration is bona fide and for genuine commercial purposes.
Neutrality is a computation
Section 110(2)(a) provides that the profits of a section 110 company are computed in accordance with the provisions applicable to Case I, and Revenue’s manual notes that this is the same wording used for the profits of a foreign trade taxed under Case III. The company is taxed on a profit figure calculated as a trade would be, after deducting its funding cost, and that cost is normally interest on profit participating notes tracking the performance of the assets.
What is left is a small retained margin, and it is on that margin that the company pays corporation tax. The charge is made under Case III of Schedule D although the computation follows the rules applicable to Case I, and section 21A charges corporation tax at 25 per cent on income chargeable under Cases III, IV and V of Schedule D. The economics depend entirely on the deduction surviving, which is why the provisions attached to subsection 4 do more work than the definition of a qualifying company.
For a continental investor the consequence is direct. If the interest on the notes is not deductible in Ireland, the vehicle pays Irish tax on income already allocated to the investor, and the return falls by an amount no closing document identified as a risk.
Where the deduction is restricted: connected recipients
Subsection 4A restricts the deductibility of profit participating interest paid to specified persons, a defined category of connected parties. Revenue’s manual describes two principal cases: where the recipient is a tax exempt entity such as a pension fund and is also a specified person, and where the interest is payable on listed debt or a wholesale debt instrument, the recipient is a specified person, and the company is aware, or is taken to be aware when the security is issued, that the interest will not be subject to tax in Ireland, another member state or a treaty country. One limb of the definition of specified person applies only where the assets, loans, advances or agreements concerned represent not less than 75 per cent of the aggregate value of the company’s qualifying assets.
Control is defined more broadly than most investors expect. The starting point is ownership or the powers conferred by the company’s constitution or other documents regulating it, but Finance Act 2019 added a subsection 7 under which a person also has control where that person has significant influence and holds, directly or indirectly, more than 20 per cent of the issued share capital, of the principal value of the notes, or of the interest payable on them. Revenue’s manual explains that significant influence means the ability to participate in the financial and operating policy decisions, and that a legal or contractual right to participate is sufficient without the person having actually participated. It also accepts that protective rights similar to those a secured creditor customarily retains in a bona fide third party financing arrangement offered by a bank, in the ordinary course of that banking business, such as consent rights or the right to remove or replace an investment manager, should not of themselves amount to significant influence.
That extension was introduced to address orphan structures, and Revenue’s manual says so. Where a vehicle has an orphan shareholding but is truly part of a group, the manual treats that as a possible indicator that the orphaning was put in place for tax avoidance purposes. An investor holding more than 20 per cent of the notes and able to participate in the financial and operating policy decisions of the vehicle should not assume the orphan structure answers the question.
Where the deduction is restricted: recipients not taxed
The second family of restrictions looks at whether the recipient is actually taxed, and it governs interest paid to persons other than specified persons. Revenue’s manual sets out four routes to deductibility under subsection 4A(b): the recipient is resident in the State or otherwise within the charge to corporation tax on the interest; the recipient is a tax exempt entity such as a pension fund in the European Union or a treaty country and is not a specified person; the interest is subject to a tax in a member state or treaty country that generally applies to profits, income or gains received from abroad; or withholding tax under section 246(2) was deducted and is not refundable.
The subject to tax route carries a condition of its own. The charge to tax abroad has to be without any reduction computed by reference to the amount of the interest or the distribution, and Revenue gives as its examples a participation exemption in respect of such interest and a notional or deemed reduction in taxable income, leaving aside reductions calculated by reference to amounts actually paid or to tax actually paid. The parallel condition for an Irish property business also excludes deemed or notional expenses calculated by reference to any financing, whether debt, equity or hybrid.
This is where the continental side of the structure becomes an Irish problem. An investor whose domestic regime shelters the receipt, through an exemption or a notional deduction, can be the reason the Irish deduction fails. A Dutch corporate investor taxed on the interest in the ordinary way, at 19 per cent on the first 200,000 euro of taxable profit and 25.8 per cent above it in 2026, is in a straightforward position. An investor holding through a vehicle that receives the interest free of tax is not, and the consequence falls on the vehicle and therefore on every noteholder.
The Irish property ring-fence
Subsection 5A restricts the use of profit participating notes in what Revenue calls the Irish property business and the legislation calls a specified property business, meaning the whole, or part, of the company’s business that involves holding or managing specified mortgages, units in an Irish real estate fund, or shares deriving their value, or the greater part of their value, directly or indirectly, from land in the State. It was the response to the use of these vehicles for Irish real estate credit. Revenue’s manual identifies four kinds of business outside it, being CLO transactions, CMBS or RMBS transactions, loan origination and sub-participation transactions, together with activities carried out in preparation for them, and it requires a single purpose vehicle for the CLO and the CMBS or RMBS cases.
The rules around the loan origination exclusion are detailed. Revenue’s manual explains that the definition relates only to the making of advances, so equity taken alongside a loan can constitute a separate specified property business within the same company, unless the value of that equity is minimal. Amounts advanced on a novation or a refinancing fall outside the definition unless the novation or refinancing is part of a bona fide commercial transaction which did not have avoiding subsection 5A as one of its main purposes.
An investor looking at an Irish credit vehicle with any exposure to Irish land should therefore ask which business the assets sit in, not merely whether the vehicle is a section 110 company. The answer is frequently that there are two businesses in one entity, with different deduction outcomes.
Interest limitation and the other overlay
Ireland’s interest limitation rule applies alongside all of this. Revenue’s guidance on the rule states that it restricts interest deductibility to 30 per cent of taxable earnings before interest, tax, depreciation and amortisation, or to the group ratio where an election is made and that ratio is higher, that it bites only where exceeding borrowing costs are above the de minimis amount of 3 million euro in a twelve month accounting period, and that it applies to accounting periods commencing on or after 1 January 2022. Where it applies it defers the deduction to later periods with sufficient earnings rather than cancelling it, and the same guidance works a securitisation through the rule, treating the payments made to the investors as deductible interest equivalent.
Withholding is the other overlay. Revenue’s notes for guidance on section 246, in the Finance Act 2025 edition, record the obligation to deduct tax at the standard rate from annual interest, and a long list of exceptions, among them interest paid by a section 110 qualifying company to a person resident in another member state or in a country with which Ireland has a tax treaty in force or signed, unless the recipient company carries on a business in the State through a branch or agency. Those exceptions are themselves subject to the outbound payments defensive measures in Chapter 5 of Part 33. Most note structures are designed into an exemption, which depends on facts about the holder that can change, and which leaves the deduction resting on one of the other conditions in subsection 4A(b).
Both are ordinary features of the Irish system rather than section 110 problems. They are mentioned because investors told the vehicle is tax neutral often read that as meaning no Irish rule applies to it.
What actually goes wrong
In practice the failures cluster. A notification filed late or not at all. Services provided to the vehicle by a sponsor without being charged for, so the arm’s length condition is not met throughout. A noteholder who acquired a large enough position, with enough influence over what Revenue’s manual calls the financial and operating policy decisions, to be a specified person under the extended control test. A recipient whose own regime sheltered the interest, so the Irish deduction failed at the far end of the chain.
Residence is the other recurring point. Revenue’s manual is direct: the company must be both resident in Ireland and carry on its business in Ireland, and where directors act independently and properly in discharging their duties and undertake the appropriate level of oversight in the company’s activities, in each case in Ireland, it is not anticipated that the company would be resident anywhere but Ireland. The manual is equally direct that directors should not take instructions from third parties. A board that signs what the sponsor sends it is describing a company managed somewhere else.
None of this makes the regime unusable. It makes it a regime whose conditions are continuous, tested against facts that change, and dependent in part on the tax position of the people who invest in it. An investor subscribing for notes issued by an Irish vehicle is not buying a static tax opinion. It is taking a position in a structure whose neutrality has to be maintained, and it is worth knowing who has undertaken to maintain it.
