Don't let the tax tail wag the investment dog
Why, in a high tax, high-transparency Ireland, investing your money well is often the smartest financial decision.
A recent Financial Times column recounted a dinner conversation that has stayed with me. A successful private equity investor was asked why he didn’t simply buy a bigger home and move in full-time with his partner in another city. His answer wasn’t about her, or the city, or the house. It was: “I couldn’t do that. I’d be paying a much higher tax rate.”
The column’s wider point was a good one: for some wealthy people, tax has ceased to be the price of a functioning society and is being treated as the enemy to be defeated at almost any cost. As Oliver Wendell Holmes put it long before any of this, “Taxes are what we pay for civilized society.” The column argued that losing sight of that has a price - sometimes the price of the society itself.
I want to make a narrower, more practical point, because the same instinct quietly costs people money. In my experience, the tax tail wags the investment dog far more often than it should.
The Irish backdrop
There’s no sugar-coating it. Outside a pension, Ireland taxes investment returns heavily. Capital gains are charged at 33%. Many fund and life-wrapper investments fall under the exit tax regime - 25% where the investment is held through a company, and 38% where an individual holds the fund directly. Income drawn personally can be taxed at marginal rates north of 50%, once USC and PRSI are counted. Against that backdrop, the urge to minimise tax is completely rational. Nobody wants to hand over a 1/3 + of a gain.
But “minimise the tax” and “maximise what you keep” are not the same objective - and people routinely confuse them. The number that actually matters is your net return: after tax, after costs, after everything. And the two of the biggest levers on that number aren’t clever structures. They’re asset allocation (what you own) and cost (what you pay to own it). Those are the things that compound, year after year, in your favour.
A tale of two €10million
Consider two people, each with a notional €10m to deploy and a five-year horizon.
Person A is determined to beat the taxman. He restructures his affairs and moves offshore so that he can eventually extract the €10m as a tax-free dividend from his company. Having spent all that energy on the tax, though, he does nothing especially clever with the money: it sits in cash inside his company. Because the company is Irish tax resident, the deposit interest is still taxed at 25%, so at around 2% gross the money grows at roughly 1.5% a year. After five years he has about €10.77m to draw down.
Person B stays in Ireland and accepts the tax bill. She leaves the €10m working inside her company, invested in equities earning around 10% a year. The company pays 25% on those gains as they accrue, so the money compounds at a net 7.5% and reaches about €14.36m after five years. She then winds the company up, and CGT at 33% applies to the whole amount left in it, not just the gain - a further bill of about €4.74m - leaving her with roughly €9.6m.
On the raw numbers, Person A edges it: his tax-free exit leaves him roughly €1.1m ahead over the five years. But look at what that edge cost. He had to emigrate, restructure his affairs and uproot his life, all to leave the money sitting in cash. Person B never moved a thing, wore two full layers of Irish tax, and still landed within touching distance.
The lesson isn’t that tax doesn’t matter - it plainly does, and two layers of it are a real drag. It’s what you do with the money matters every bit as much, and the prize for going offshore proved modest. For most people, a gap of that size is a price well worth paying to stay put, keeping their home, their family and their peace of mind intact.
That is, admittedly, a deliberately extreme example. But it is far from an uncommon mindset, in our experience.
Other ways the tail wags the dog
The same instinct shows up in far more everyday decisions. A few we come across regularly:
- Holding a large, concentrated stock position (a pile of Google shares, say) and refusing to diversify, purely to avoid the CGT on switching. Worse still, US shares count as US-situs assets and can attract US federal estate tax of up to 40% on death, with only a $60,000 exemption for non-US individuals.
- Not rebalancing back to a target allocation, because doing so would crystallise a taxable gain.
- Never selling anything down to actually spend, give and enjoy life; for fear of the tax consequences.
- Funnelling every last cent into a tax-efficient pension, at the expense of other things that matter, such as buying or trading up to a home you’d love.
- Emigrating to a low-tax jurisdiction (Cyprus, the UAE and the like) for the tax treatment, while underweighting the real trade-offs: family, friends, quality of life and the social scene you’d leave behind.
That last route is also getting harder. Going offshore is no longer as straightforward as perhaps it once was. Portugal’s Non-Habitual Resident regime, for years the default landing spot, closed to new applicants in 2024, and the remaining options are fewer and more demanding.
To be clear, none of this means moving abroad is a mistake. If a move genuinely suits your life (the climate, the people, the pace, where your family already is), then it can be a great decision, and favourable tax treatment is simply a welcome bonus on top. The point is that tax should be the bonus, not the whole reason for upending your life.
The risk nobody prices correctly
There’s a second reason to be wary of building a plan around aggressive tax avoidance, and it has nothing to do with arithmetic.
We now live in a world of near-total financial transparency. Under the Common Reporting Standard and the various automatic exchange-of-information regimes, banks and authorities routinely share account data across jurisdictions. The offshore account that once felt private is now, in all likelihood, already visible to Revenue. Structures that depend on information not travelling are built on sand.
This is why tax compliance has never mattered more. A generation ago, a tax advisor earned their keep mainly through clever planning. Today, getting it right - full, accurate, on-time disclosure that stands up to scrutiny - is at least as valuable as anything done to reduce the bill. A good accountant or tax advisor should be measured as much on keeping you squarely on the right side of Revenue as on the savings they find you. In this environment the two are not in tension: robust compliance is the planning.
So weigh the two risks honestly. Equity-market volatility is a known, well-understood and, crucially, rewarded risk. It is uncomfortable, it is temporary, and historically those who tolerate it are paid for doing so. Pushing the envelope on tax in a data-sharing world is a very different animal: an asymmetric risk where the downside (interest, penalties, professional fees, audits, reputational damage and worse) can swamp the saving you were chasing, often years later when you’d long since stopped thinking about it.
Given the choice, I’d take the volatility every time.
What is it all for?
Even if you do extract the money perfectly tax-free, a harder question waits on the other side: what are you actually going to do with it? Money is only ever a means to something: a comfortable retirement, helping your children or grandchildren when it matters most, supporting causes you care about, leaving things in good order. Seen that way, estate planning and thoughtful, targeted gifting are at least as important as the rate you pay getting the money out.
Ireland’s Capital Acquisitions Tax is charged at 33%, and sensible use of the tax-free thresholds, the annual small-gift exemption and well-timed gifts can pass far more to the next generation than shaving a point or two off an investment return ever will. The extraction is rarely the hard part; knowing what the money is for and getting it to the right people at the right time, usually is.
The point
None of this is an argument for paying a euro more tax than you owe. Use your pension allowances, your reliefs, your CGT exemptions - all of it. Tax efficiency is part of good planning.
But it is only part. For a great many people, the bigger prize sits on the other side of the ledger entirely - in owning the right assets, keeping costs low, and giving the money time to compound. Beyond a point, the energy spent shaving tax would be far better spent making the underlying capital work harder.
Don’t let the tax tail wag the investment dog.
