When you run a group structure, your “exit” is not always a full company sale. Sometimes it is a subsidiary disposal. Sometimes it is a reorganisation before fundraising. Sometimes it is moving assets into the right entity so risk is ring-fenced.
The problem is that these transactions can create tax leakage in places founders do not expect. A group can look clean on a chart, but messy in tax reality. A sale that is “mostly exempt” can still leave a meaningful taxable slice. A capital gains exemption can be undermined by stamp duty, fees, or poor sequencing. And if you are running a cross-border setup, you also have to consider where the company is actually taxed, not just where it is incorporated.
This guide is for high-earning freelancers, founders, and owner-operators who use HoldCos or multi-entity setups across Europe, especially with Germany and Ireland in the picture. We will explain the core idea of participation-style capital gains exemptions, then anchor it in two practical rules: Germany’s effective 95% exemption and Ireland’s participation exemption plus the commercial reality of 1% stamp duty on many share transfers.
For background reading, see What changed in 2026
The headline mechanics in this article have not been rewritten for 2026. Germany’s corporate participation exemption still generally works as a 95% effective exemption because 5% of the gain is treated as a non-deductible expense. Ireland’s participation exemption for certain disposals of subsidiary shares still hinges on qualifying conditions under Irish legislation and Revenue guidance. And Ireland’s stamp duty on share transfers remains 1% in many standard cases.
What has changed is how often these points show up in diligence and deal negotiations. Buyers model every friction cost and challenge assumptions quickly. That pushes founders to prepare earlier: document ownership and holding periods, validate trading status, and model stamp duty and professional costs before signing an LOI.
If you are also operating cross-border, the “management and control” question has become more important in practice. In our article we delve deeper into the topic and help you understand and answer this question for you case. The concept in one page: what “group capital gains exemptions” really mean
A group capital gains exemption is a rule that reduces or removes corporate tax on gains when one company sells shares in another company, typically a subsidiary. In plain English: if a Holding Company (HoldCo) owns a meaningful stake in an Operating Company (OpCo) and later sells it, the gain may be exempt (fully or mostly), so profits are not taxed repeatedly as value moves up the chain.
Why does this exist? Because without these rules, value created inside a subsidiary can be taxed once as operating profit, then taxed again when the parent sells the shares. Participation exemptions aim to reduce this double taxation and support normal business restructuring.
Two quick clarifications:
•Exemption vs deferral: an exemption removes tax on a gain (subject to conditions). A deferral postpones tax to a later event. If you model an exemption as a deferral, you can misprice a deal.
•Don’t mix the tax types: a capital gains exemption is not the same thing as stamp duty, and neither is the same as withholding tax. Capital gains tax is about profit on disposal. Stamp duty is a transaction tax triggered by the legal transfer instrument in certain jurisdictions (Ireland is a common example). Withholding tax is typically about dividend, interest, or royalty flows, not the gain on selling shares.
Now, let’s make this concrete with Germany and Ireland.
Germany: the 95% exemption in practice
Germany is often described as having an effective 95% exemption for corporate share disposals. The key is what that headline actually means.
Under ), capital gains from the sale of shares by a corporate seller are generally excluded from taxable income. However, 5% of the gain is deemed a non-deductible business expense, so the practical result is that 95% is exempt and 5% is effectively taxed. Why the “5% add-back” matters in deals
For founders, the most common mistake is to treat “95% exempt” as “close enough to zero to ignore”. It is not always ignorable:
•If the gain is large, 5% can still be meaningful.
•If you are also paying professional fees, success fees, or internal reorganisation costs, you need to understand where they land in the accounts and how they interact with the exemption mechanics.
•If the structure is changing shortly before the sale, timing and documentation can become the real risk, not the headline exemption.
A practical point that comes up in real transactions is the treatment of deal costs. Germany’s framework can create counterintuitive outcomes where the gain is largely exempt, but the deductibility of associated costs becomes a point of technical and financial attention.
Mini-scenario: German HoldCo sells OpCo
A German Holding Company sells 100% of its Operating Company to a strategic buyer. The gain is largely exempt, but 5% is treated as a non-deductible expense, so you model an effective taxable slice rather than assuming a clean zero.
The planning takeaway
Germany’s 95% outcome can be powerful, but only if you do three things early:
1.confirm you are modelling the right seller (corporate vs individual matters),
2.model the taxable slice and costs properly,
3.keep your evidence and governance clean so the structure holds up in diligence.
For founders considering relocations or major structural changes before a sale, also see Ireland: subsidiary share disposals plus the 1% stamp duty reality
Ireland is frequently used in European group structuring for commercial and tax reasons, but it is important to separate two layers:
1.capital gains tax on the disposal, and
2.stamp duty on the share transfer instrument.
Ireland’s participation exemption at a high level
Ireland provides an exemption from tax on certain gains arising on disposals of shares in subsidiaries, where specific conditions are met. The conditions are detailed, but at a high level they revolve around the investor company’s holding and the nature of the investee’s activities (with anti-avoidance and boundary rules).
The practical takeaway is not “Ireland is exempt”. The practical takeaway is: you need an eligibility screen before you assume the gain is out of charge.
The stamp duty layer: 1% can be the real cost
Even where a disposal is exempt from capital gains tax, Ireland often charges stamp duty at 1% on instruments transferring shares.
Commercially, this matters because:
•stamp duty is based on consideration (or market value in some cases), which can make it feel like a clean “deal tax”
•it is often a negotiation point in the SPA, particularly where margins are tight or the buyer is financial
•it is easy to forget in early modelling because it sits outside the “corporation tax on gains” headline
Market practice frequently places the obligation to pay stamp duty on the purchaser, but that does not mean it is “not your problem”. If you are the seller, it still affects price, completion mechanics, and how the deal is negotiated.
Mini-scenario: Irish HoldCo sells subsidiary shares
An Irish HoldCo sells shares in a trading subsidiary. The gain may qualify for Ireland’s participation exemption, but the buyer still models 1% Irish stamp duty on the share transfer documents and pushes on price or terms accordingly.
The planning takeaway
In Ireland, founders usually get caught by one of two issues:
•assuming the participation exemption applies without doing the conditions check, or
•treating stamp duty as “admin” rather than a real cost that changes negotiation dynamics.
If your Irish company is operated from abroad, read and Decision-support: eligibility and deal-readiness checklist
Use this checklist before you restructure, sign an LOI, or begin buyer conversations. It is designed to surface the issues that most often blow up timelines and pricing.
1) Ownership and holding evidence
•Can you prove ownership percentage and chain of title from day one (cap table, share certificates, registers)?
•Do you have clean dates for when each stake was acquired, changed, or transferred?
•If there were historic reorganisations, are the agreements, valuations, and board approvals archived and searchable?
2) Trading vs investment profile
•Is the subsidiary clearly trading, or does it hold a large investment portfolio or passive assets?
•Does the group have assets that can change the “character” of the entity in diligence (cash piles, IP in the wrong place, property held inside OpCos)?
•If there is a mixed asset profile, do you know how that affects eligibility for reliefs and exemptions in the relevant jurisdiction? (This is where you need local advice, not assumptions.)
3) Governance and substance basics
•Where are strategic decisions made in reality, and do your board minutes match that reality?
•Do you have documented directors’ decisions, not just operational chat logs?
•If you run a cross-border setup, have you checked “management and control” risk? (See .) 4) Costs you must model early
•The taxable slice in Germany (the 5% add-back effect) and how deal costs interact with it.
•Ireland’s 1% stamp duty on the share transfer instrument.
•Legal, tax, and advisory fees, including sell-side diligence and SPA negotiation.
Common mistakes we see in real founder-led deals
Treating exemptions as the strategy. Exemptions are a tool, not a plan. The plan is a defensible structure, clear governance, and clean evidence.
Restructuring too late. If you start moving entities around after a buyer shows up, you increase tax risk, diligence risk, and execution risk. Early structuring is usually cheaper than late “deal firefighting”.
Forgetting friction costs. The transaction can be “tax-exempt” and still expensive. Ireland’s stamp duty is the obvious example, but professional fees and timing costs can be just as material.
Ignoring where the company is actually taxed. Incorporation location is not the same as corporate tax residence in many real-world cases. If you operate an Irish company from Germany, you cannot ignore management and control principles.
Practical steps: how to plan a subsidiary sale or group reorganisation
Step 1: Map the group and define the outcome
Write down the target end-state in one sentence. For example: “Sell OpCo shares to a buyer” or “Move IP into HoldCo before raising”.
Then map the group as it exists today, including ownership, assets, bank accounts, IP, and where decisions are made.
Step 2: Decide whether it is a share sale or asset sale
This is a commercial decision as much as a tax one. Participation-style exemptions generally relate to selling shares. Asset deals can create a different tax profile entirely.
Step 3: Run an eligibility screen early
Do not rely on rules you heard on Twitter or in founder circles. Screen the relevant exemptions and reliefs in the seller’s jurisdiction and confirm the facts match the conditions. For Ireland, start with the participation exemption framework and Revenue guidance.
Step 4: Model the full economics
Build a simple model that includes:
•taxes you expect (including any “taxable slice” mechanics in Germany)
•stamp duty where relevant (Ireland’s 1% in many share transfers)
•fees and completion costs
If the numbers do not work in a conservative model, they will not work in a buyer-led model.
Step 5: Build the evidence pack as you go
Diligence is easier when you are not reconstructing history under pressure. Keep:
•board minutes and resolutions
•shareholder registers and transfer documents
•key contracts and IP assignments
•clear records of where decisions are taken

Conclusion: request a group structure review
If you are planning a subsidiary sale, a group reorganisation, or simply want to ensure your Germany or Ireland structure is deal-ready, Richmond Blackwood can help you stress-test it before you sign an LOI. A structure review focuses on defensible governance, clean documentation, and realistic modelling, including friction costs like Ireland’s stamp duty and Germany’s taxable slice mechanics.
