The right long-term plan for a St Moritz-connected family is one where residence, holdings, succession and governance are designed together, not bolted on one at a time. Get the sequencing wrong and you end up with a foundation that clashes with your tax residency, or a succession plan that ignores where you actually live.
Start this week with a short checklist:
- Run cantonal tax modelling before you touch anything else
- Confirm which residency test applies to you (30 days with work, 90 days without)
- Review whether your home jurisdiction’s inheritance rules conflict with Swiss succession law
- Agree a governance framework with anyone who shares control of the family’s assets
- Book a first conversation with a Swiss adviser who works across all four areas
Wealth structuring works best as a coordinated process where residence, legal vehicles and governance reinforce each other rather than pulling in different directions. Marmot Finance is a practical place to start that modelling conversation.
Key Takeaways
Long-term financial planning for St Moritz-connected families works only when residence, legal structure, succession and governance are modelled together from the start.
What does long-term financial planning in St Moritz actually cover?
A proper plan for families with ties to St Moritz has six moving parts, and missing any one of them tends to undo the others. Residence and tax sit at the base, because where you’re legally resident decides almost everything else that follows. Then come the legal vehicles that hold your wealth, the succession plan for passing it on, the governance structure that keeps decisions sane across generations, an investment and risk framework, and often a philanthropic layer too.
For a family relocating to the Engadin, that might mean weighing up lump-sum taxation against ordinary taxation before buying a chalet, because holiday-home ownership changes your tax exposure in ways many people don’t expect. For a family that already has a foundation set up abroad, it might mean checking whether that structure still makes sense once someone in the family becomes Swiss tax resident.
Each part typically has a different lead adviser:
- A tax adviser models cantonal outcomes and residency scenarios
- A private-client lawyer drafts or reviews the legal vehicles and succession documents
- A family office or wealth manager coordinates governance, investment strategy and ongoing reporting
None of these people should be working in isolation. The whole point of long-term planning is that the tax adviser’s assumptions match the lawyer’s structure, which matches the investment strategy.
Which legal structures should you actually consider?
Four tools come up again and again in Swiss private-client work, and each solves a different problem. Understanding what each one is for saves you from picking the wrong one just because it sounds prestigious.
A holding company sits between you and your operating businesses or investment portfolios, ring-fencing liability and often improving tax treatment on dividends and capital gains. It’s flexible, relatively cheap to run, and doesn’t lock your wealth away from you the way a foundation does.
A Swiss family foundation can hold and manage assets for the benefit of family members, but Article 335 of the Swiss Civil Code restricts its purpose to things like education, welfare support and helping someone get established in life. General maintenance payments, the kind many families actually want, fall outside what the law currently allows.
A Liechtenstein foundation avoids that restriction and remains one of the most common alternatives for families who want a foundation structure with broader purposes. A foreign trust, recognised in Switzerland thanks to the Hague Trust Convention, gives similar flexibility with different governance mechanics, particularly useful for Anglo-Saxon families used to trust law.
Swiss law simply doesn’t offer a domestic trust regime, and its family foundations can’t cover general maintenance. That single gap explains why so many mobile, wealthy families end up structuring through Liechtenstein or a foreign trust instead of staying purely Swiss.
Families with forced-heirship exposure, meaning a home country that reserves a fixed share of an estate for children or a spouse regardless of the will, need to check this early. Choice-of-law elections and the vehicle you pick can either soften or aggravate that exposure, so this isn’t a decision to make on aesthetics.
Worth watching: Parliament approved a motion in 2024 asking the Federal Council to draft legislation that could eventually widen what Swiss family foundations are allowed to do. Nothing has changed in law yet, so don’t structure around a reform that hasn’t happened.
How does Swiss residency change your tax position?
Residence is the lever that moves everything else, and it’s worth getting the mechanics straight before you think about anything more sophisticated. Meet either residency test, 30 days if you work in Switzerland, 90 days if you don’t, and you generally become liable for Swiss tax on your worldwide income and wealth, not just what’s Swiss-sourced. Fall short of both tests and you’re only taxed on Swiss-source income and Swiss-situs assets, which is a very different starting point.
For qualifying foreign nationals who take up Swiss residence without working here, lump-sum taxation (also called expenditure-based taxation) remains an option. The taxable base is whichever is highest: your actual living costs, a federal minimum of CHF 421,700 as of 2025, or seven times your annual rental value. Cantons then apply their own multipliers on top, so the real number varies significantly depending on where you settle, and the Engadin region has its own local calculation worth modelling separately from, say, Geneva or Zug.
If you’re supplying assumptions to whoever runs this modelling for you, give them real numbers: expected portfolio growth, the rental multiplier on your property, and your household composition, since spouses and dependants change the calculation.
Pro Tip: Model at least two or three cantons before you commit to one, and keep a paper trail showing genuine commercial and personal substance behind wherever you land. Tax authorities scrutinise rulings that look like they exist purely on paper, and documented substance is what makes a ruling defensible if it’s ever questioned.
When do you need a family office, and what does it cost?
Not every wealthy family needs a family office in the full staffed sense. The spectrum runs from outsourcing everything to a wealth manager, through a lean single-family setup with one or two internal staff, up to a fully staffed operation with its own investment, tax and legal team.
The regulatory line matters more than the size question. Single-family offices that serve only lineal relatives are generally exempt from FINMA’s portfolio-manager licensing regime. The moment you manage capital for extended family, friends, or any third party outside that lineal relationship, you’re typically pulled into licensing requirements, and FINMA applications average nine to 11 months to process.
Before assuming you’re exempt, work through a short checklist:
- Document exactly who counts as a lineal relative under the structure
- Map every fee arrangement to confirm nothing looks like third-party asset management
- Record the actual activities performed, not just the intended scope
- Reassess the exemption whenever a new family member or asset class is added
Lean single-family offices typically run with a handful of staff covering investment oversight, tax coordination and reporting, while multi-family arrangements spread those costs across several households. Either way, budget for solid IT and cybersecurity infrastructure, clear bank relationships, and a governance cadence, quarterly reporting at minimum, that keeps everyone informed without drowning them in paperwork.
How do you choose the right adviser for your family?
Coordinated advice beats brilliant advice given in isolation, every time. A tax adviser who doesn’t talk to your lawyer, who doesn’t talk to whoever manages your investments, is how families end up with structures that contradict each other.
Work through engagement in stages:
- Discovery — a genuine conversation about goals, family composition and existing structures, not a sales pitch
- Scope — a written outline of exactly what will be modelled and delivered
- Evidence gathering — proof of real Swiss private-client experience, not just general wealth management credentials
- Conflict checks — confirmation that no adviser has a competing interest in the outcome
- Fees and deliverables — a clear fee structure agreed before work begins
Watch for red flags along the way. Advisers who give recommendations in a silo, who never mention residency modelling or succession implications, who resist documenting the commercial substance behind a structure, or who won’t coordinate with your other professionals, are all worth walking away from.
Good outputs look specific: coordinated modelling that shows the same assumptions across tax and legal documents, written governance policies rather than verbal understandings, properly escrowed foundation or trust deeds, and clarity over who owns the intellectual property in any reporting tools you’re given.
What is a realistic timeline and budget?
Set expectations early, because long-term planning genuinely takes time. Relocation combined with a lump-sum tax application often runs four to nine months from first modelling to a signed ruling. Setting up a foundation or trust structure typically adds another three to six months once the tax position is settled. Family-office establishment, if you’re going that route, can run in parallel but usually takes six to 12 months to be fully operational.
One-off setup costs vary hugely with complexity, covering legal drafting, notary fees and, for a foundation, an initial endowment. Ongoing annual running costs then cover administration, reporting and adviser retainers.
Tie your review calendar to real events, not just the calendar year:
- A property sale or acquisition
- Relocation to a new canton or country
- A birth, marriage or death in the family
- Any material change in asset allocation
For anything involving a FINMA application or a formal tax ruling, budget more than nine months and build in time for the back-and-forth those processes usually require.
How does Marmot Finance approach long-term planning for families?
Marmot Finance works through this in a set sequence, because skipping steps is how families end up with structures that fight each other. The process starts with discovery, understanding what a family actually wants across generations, not just this year’s returns. From there it moves into cantonal tax modelling, vehicle selection matched to the family’s real circumstances, governance design that spells out who decides what, and implementation followed by ongoing coordination between all the moving parts.
In practice this has meant helping families install a written governance framework where none existed, clarify a succession plan that had been informally agreed but never documented, and model their tax position across more than one canton before a relocation decision.
- Discovery and goal-setting with the whole family, not just the primary decision-maker
- Cantonal modelling before any structure is chosen
- Governance and succession design run alongside, not after, the tax work
- Ongoing review built into the mandate from day one
If you want to see how this works for the Engadin specifically, Marmot Finance’s St Moritz service page is the natural next stop.
What happens to family wealth across generations without a plan?
Most family fortunes don’t survive contact with the third generation, and it’s rarely the investments that fail. Practitioners consistently point to weak governance, not poor returns, as the reason wealth disperses. Money that took one generation decades to build gets split, mismanaged or fought over within twenty years because nobody wrote down who decides what.
Governance for a multi-generational family doesn’t need to be complicated, but it does need to exist in writing. That usually means a family charter or constitution setting out decision rights, a defined process for bringing in-laws or new generations into the fold, and clear rules for how disputes get resolved before they reach a courtroom.
Forced heirship is where this gets genuinely tricky for cross-border families. Many European jurisdictions reserve a fixed share of an estate for children or a spouse, regardless of what a will says, and that reservation can override a Swiss-style plan if the deceased was legally domiciled or held assets in one of those countries. The choice-of-law provisions in your will, and where you’re actually resident when you die, both affect which rules apply.
Succession planning, done properly, sits alongside the legal structures rather than after them. A holding company or foundation only works if the succession document says clearly who inherits control, not just who inherits value. Families who separate these two conversations, structuring first and succession later, often discover the structure doesn’t actually deliver the outcome they wanted.
Why should residence, holdings and succession be planned together?
Treating these four areas as separate projects is the single most common mistake affluent families make, and it’s an expensive one to unwind later. Wealth management works best as a coordinated strategy where legal structures, residence choices and investment allocation are designed together from the outset, precisely because a decision in one area quietly changes the maths in another.
Consider a family that sets up a holding company for tax efficiency, then relocates to a canton with a very different wealth tax rate, then only afterwards drafts a succession plan. Each decision made sense on its own. Together, they might mean the holding structure no longer delivers the tax benefit it was built for, or the succession plan assumes a residency status that’s since changed.
The fix is sequencing, not perfection. Residence modelling should generally come first, since it determines the tax and succession law framework everything else operates inside. Legal vehicles come next, chosen to fit that residence position rather than the other way round. Governance and succession documents follow, written to match the actual structure in place, not a generic template. Investment strategy and risk management then sit on top, informed by all three.
This is exactly the coordination gap that trips up families who work with siloed advisers. A long-term wealth planning approach built around this sequence, rather than four separate projects run by four separate professionals, tends to hold together far better when circumstances change.
How should you manage currency risk and cross-border assets?
Families connected to St Moritz rarely hold wealth in a single currency, and that’s before you account for property, business interests or investment portfolios sitting in different countries. Swiss francs, euros and, for many international families, US dollars all show up somewhere in the balance sheet, and currency movement between them can quietly erode returns that look fine on paper.
The practical response isn’t to try to predict exchange rates, which nobody does reliably, but to match currency exposure to future spending needs. If school fees, a second home, or eventual retirement spending will happen in euros, holding a meaningful chunk of the portfolio in euro-denominated assets reduces the risk of a bad exchange rate hitting you exactly when you need the money.
Multi-jurisdictional asset allocation adds another layer. Property in one country, a business in another, and liquid investments split across Swiss and European accounts each carry different tax treatment, different reporting obligations, and different liquidity profiles. A portfolio built without reference to where the money will actually be spent, or which jurisdiction taxes each asset class, tends to underperform a simpler portfolio built with that coordination in mind.
This is one area where digital tools genuinely help, giving families a single view across currencies and jurisdictions rather than reconciling several bank statements by hand every quarter. It’s also a case where a hybrid approach, human judgement on the strategic allocation paired with digital tracking of the actual positions, tends to catch problems that a purely manual or purely automated process would miss.
What risk management steps make sense for St Moritz families?
Wealth concentrated in property, a single business, or one currency carries risks that a diversified investment portfolio doesn’t automatically solve. St Moritz-connected families often hold significant value in a chalet or estate, and that concentration deserves the same scrutiny you’d apply to a large single stock position.
Asset protection starts with structure. Holding property and liquid investments in separate legal vehicles limits the damage if one asset class runs into trouble, whether that’s a liability claim, a market downturn, or a family dispute. Insurance plays a bigger role here than many families assume, covering not just the property itself but liability exposure that comes with owning a high-value home in a canton with its own local risk profile, from winter weather damage to guest liability.
Diversification across asset classes and geographies remains the most reliable defence against any single shock, but it needs to be paired with liquidity planning. A family with most of its wealth tied up in property or a private business can find itself unable to meet a tax bill or a succession obligation without a forced sale at a bad time. Keeping a portion of the portfolio genuinely liquid, and reviewing that liquidity buffer whenever a major life event approaches, prevents that scenario.
Governance itself is a risk management tool, not just an administrative nicety. Clear decision-making rights reduce the chance that a disagreement between family members turns into a costly legal dispute, and documented processes give everyone a framework to fall back on when emotions run high, which they usually do around money and inheritance.
How can philanthropic giving fit into a long-term plan?
Charitable giving works best when it’s planned alongside the rest of the structure, rather than treated as an afterthought once the tax and succession questions are settled. Swiss and international vehicles both offer routes into structured philanthropy, and the right choice depends on how much control the family wants and how international the giving will be.
A Swiss charitable foundation gives you a recognised, tax-efficient vehicle for giving within Switzerland, with its own governance and reporting obligations. Families with a genuinely international outlook, wanting to support causes across several countries, often look instead to a foreign foundation structure or a donor-advised fund set up abroad, which can offer more flexibility in where and how funds are distributed.
Either route lets philanthropy become part of the family’s governance story, not just a tax line item. Involving the next generation in decisions about where money goes tends to build the same kind of engagement that keeps a family aligned on the rest of the wealth plan, and many advisers now treat philanthropic planning as a genuine succession tool, giving younger family members real decision-making experience before they inherit control of anything larger.
Timing matters too. Structuring charitable giving before a major liquidity event, a business sale or a large capital gain, can be more tax-efficient than giving afterwards, so this is worth raising early in the planning conversation rather than as a year-end afterthought.
How do Swiss inheritance rules compare with other countries?
Cross-border families face a genuine tension here, and it catches people out more often than any other part of the plan. Switzerland’s own succession rules changed materially from 1 January 2025, when revisions to the country’s private international succession law took effect, giving people more flexibility to choose which country’s law governs their estate and reducing some of the jurisdictional conflicts that used to trip up multi-national families.
That matters because many European countries operate forced heirship rules that Switzerland doesn’t apply in the same way. A French or Italian domicile, for instance, can reserve a fixed share of an estate for children regardless of what a will says, while Swiss law traditionally offered more freedom to distribute assets as the deceased chose, within its own reserved-portion rules for close relatives.
For a family split across two or three countries, this isn’t an abstract legal point, it decides who actually inherits what. The new choice-of-law flexibility means a Swiss-resident individual with connections abroad may now be able to elect Swiss law to govern their estate, sidestepping a stricter forced-heirship regime elsewhere, but that election needs to be made correctly and in writing to hold up.
This is exactly the kind of detail that gets missed when succession planning happens in isolation from residence and tax modelling, since the choice-of-law election interacts directly with where you’re resident and where your assets sit.
What should you expect when engaging a Swiss adviser?
Onboarding with a serious Swiss adviser usually starts with a discovery conversation that goes well beyond your current portfolio, covering family structure, existing legal vehicles, residency history and long-term goals. Expect to be asked for documentation early: prior tax returns, existing trust or foundation deeds, and details of assets held outside Switzerland.
From there, a good adviser produces a written scope before any structural work begins, setting out exactly what will be modelled, what deliverables you’ll receive, and on what timeline. Ongoing communication should follow a predictable rhythm rather than only happening when something goes wrong, typically a light annual check plus deeper reviews whenever a material event happens, a sale, a relocation, a birth, a death, or a significant market shift.
Ask directly how the adviser coordinates with your lawyer and tax specialist, because that coordination is where most value gets lost or gained. An adviser who works in isolation from your other professionals, however competent individually, tends to produce a plan with gaps at the seams. One who insists on joint calls or shared documentation across the team is doing the coordination work that actually protects your position over time.
A closing thought on timing
Delay is the most expensive decision families make in this area, not because any single year of inaction causes disaster, but because misaligned structures compound quietly until a sale, a death or a move forces the issue. Book an initial review now, and treat it as the start of a periodic habit rather than a one-off project, because Swiss law and family circumstances both keep moving.
How can Marmot Finance help you build this plan?
Marmot Finance is the FINMA-accredited option for St Moritz-connected families who want their tax, succession and governance work handled as one coordinated plan rather than three separate conversations with three separate firms. That coordination is the exact gap that trips up families working with siloed advisers, and it’s the thing Marmot builds its process around from the first meeting.
The firm combines personal consultations with digital tools like the Money Makeover Quiz and ongoing financial coaching, so you get both an expert sounding board and a clear, trackable view of where your plan stands. Engagement typically starts with a fee-based modelling conversation covering your residence and tax position, with an optional ongoing mandate if you want continued portfolio management and governance support afterwards.

Frequently asked questions
What is the first step in long-term financial planning for a St Moritz-connected family? Residence modelling comes first, because it decides which tax regime and succession law framework everything else has to work within.
Do I need a family office if I already have a wealth manager? Not necessarily. Many families are well served by an outsourced or hybrid model, and only need a fully staffed family office once complexity or third-party involvement grows significantly.
Can a Swiss family foundation pay for a grandchild’s living costs? Generally not under current law. Article 335 of the Swiss Civil Code limits family foundations to purposes like education and welfare, not general maintenance, which is why many families use a Liechtenstein foundation instead.
How does lump-sum taxation affect long-term planning? It sets your taxable base at the higher of your living costs, the federal minimum, or seven times your annual rent, with cantonal multipliers on top, so it needs modelling before you commit to a canton.
How often should a long-term financial plan be reviewed? A light annual check plus a deeper review around major life events, a sale, relocation, birth or death, keeps the plan aligned with both the law and your family’s actual circumstances.
