Families preserve wealth by combining three things: clear legal documents that reflect their actual wishes, tax-aware timing on property and investments, and steady, disciplined portfolio management. The most urgent first steps are centralising documents and liquidity, updating wills and marriage contracts, and booking a canton-specific tax check before any property sale. For families who want hands-on guidance, FINMA-accredited specialists such as Marmot Finance can help turn this plan into action.
TL;DR:
- Create one inventory of property titles, account numbers, insurance policies, liabilities, and password access, and ensure an executor can reach it without your phone.
- A will remains subject to protected heirs’ statutory shares, while a notarized inheritance contract requires every party’s consent and binds signatories to agreed outcomes.
- Valais property gains tax falls with longer ownership, and reinvesting primary residence proceeds can defer payment, while transfer taxes and local supplements remain.
- Swiss inheritance tax is cantonal: spouses are exempt everywhere, direct descendants in most cantons, and more distant beneficiaries may face higher rates.
- Mountain resort property is less liquid, and tourism shifts can weaken rents and resale demand; keep cash and diversified investments to avoid a rushed sale.

Practical priority checklist: what to do in the next 3 to 12 months
Wealth preservation rarely fails because of bad investments. It fails because of missing paperwork, unclear ownership, and families who never had the conversation until it was too late. The following steps take most families a few months, not years, and they reduce exposure immediately.
- Build a complete inventory of assets and liabilities, including property titles, account numbers, and insurance policy details, and keep it in one place both you and your family can find.
- Set aside accessible cash to cover likely taxes and estate costs. A cantonal tax check gives you a realistic figure rather than a guess.
- Confirm the legal status of your partner and dependants, since cohabiting or unmarried partners often have far weaker inheritance rights than spouses.
- Write or update your will, and record where digital account passwords and access credentials are stored, ideally with a trusted executor or notary.
Each of these tasks has a natural professional attached to it: a notary for binding legal documents, a cantonal tax advisor for property-specific questions, and a wealth manager familiar with FINMA requirements for the investment and governance side.
Pro Tip: Store your document inventory somewhere your executor can access without needing your phone passcode, a surprising number of estate delays start right there.
Estate planning instruments: will, Ehevertrag, Erbvertrag and lifetime gifts
A will lets you express preferences but still operates within the legal shares that protected heirs are entitled to. An Erbvertrag, a notarised inheritance contract, binds all signing parties and can override some of those statutory expectations where the law allows it, which makes it the stronger tool when a family needs certainty rather than flexibility.
A few distinctions matter when deciding which instrument fits:
- A will is simpler to draft and amend but cannot bind heirs to an agreement the way a contract can.
- An Erbvertrag requires a notary and the consent of all parties, which suits families who want a settled, unchallengeable outcome.
- An Ehevertrag, a marriage contract choosing the matrimonial property regime, changes what counts as the shared estate before inheritance rules even apply, which materially affects what a surviving spouse keeps outright.
- Lifetime gifts can simplify succession and reduce the taxable estate later, but they raise clawback and documentation questions, so keep receipts, valuations, and a written record of intent for every significant gift.
The practical rule across all of these: anything that materially changes ownership or inheritance expectations belongs in a notarised document, not a verbal understanding between family members.
Property and tax: capital gains, transfer tax and deferral options in Zermatt
Property is often the single largest asset in a family’s estate, and it carries its own tax mechanics that catch people off guard. In Valais, private property sales are subject to a Grundstückgewinnsteuer, a property gains tax, that falls as the holding period lengthens.
- The tax follows a degressive schedule: the longer you hold a property, the lower the rate, with reductions building year on year after the early holding period.
- Transfer and registration taxes apply separately on the sale itself, and municipalities can add their own supplements, so the total burden varies by commune, not just by canton.
- Valais tax statutes allow a deferral, not a cancellation, of the property gains tax when proceeds from a primary residence are reinvested into a replacement home. The liability is postponed, and it resurfaces on a future sale unless you defer again.
One figure worth knowing: Valais charges a Grundstückgewinnsteuer on private property sales that decreases with a longer holding period, and two-thirds of the revenue flows directly to the municipality, which is part of why local offices take these assessments seriously and why timing a sale matters financially, not just emotionally.
Before selling, run the numbers through a cantonal calculator, check with the municipal office about any local supplements, and keep liquidity ready to cover a provisional assessment while the final figure is confirmed.
Governance and structures: family offices, fiduciaries and regulatory thresholds
Not every family needs a formal structure. Many do fine with powers of attorney, regular family meetings, and a shared document system. Formal structures such as a family office or a foundation make sense once the estate is complex enough that informal coordination starts breaking down, or once multiple generations are actively involved in decisions.
- Simple governance works when one or two decision-makers manage the estate and the family trusts the arrangement.
- Formal structures suit families managing diverse asset classes, multiple properties, or several branches of the family with competing interests.
- A key regulatory line sits here: managing third-party discretionary portfolios typically requires FINIG asset-manager authorisation from FINMA and oversight by a recognised supervisory organisation, while purely in-house management of a single family’s own capital is usually treated differently, provided there is genuine operational substance behind it.
- Documented mandates, clear signatory limits, and an occasional external compliance review add discipline without triggering a full regulatory regime.
Pro Tip: Before building a family office, ask whether a documented mandate with an external wealth manager achieves the same outcome at a fraction of the cost.
Investment principles for preservation: portfolio shape and generational rules
Preserving wealth through investing is less about finding the best return and more about not losing ground to taxes, fees, or poor timing. A few rules hold up across most family situations.
- Keep a liquidity buffer sized to cover expected taxes and settlement costs, held separately from the long-term portfolio so a tax bill never forces a bad sale.
- Diversified ETF and fund portfolios tend to offer cost-effective exposure, and equity allocation should reflect the time horizon of the family as a whole, not just the oldest generation.
- Tax-efficient account structures and pension considerations matter where they apply, and a clear withdrawal policy for heirs avoids disputes later.
- Writing a short investment policy statement for family assets, covering risk tolerance, time horizon, and rebalancing rules, keeps decisions consistent even when the people making them change.
How Marmot Finance supports families turning a plan into action
Our wealth management mandates sit alongside financial coaching and hybrid digital tools, including the Money Makeover Quiz and planning workshops, built specifically for families and women navigating these decisions. Rather than treating investing and estate planning as separate problems, we work through them together.
A typical engagement starts with a review of existing documents, moves into a tax-aware property planning session where relevant, and finishes with a portfolio health check and a concrete implementation plan.
- Bring your estate documents and recent tax returns to the first session so the conversation starts from facts, not assumptions.
- Expect a small initial mandate or planning package before committing to a full wealth management relationship.
- Use the session to flag any property sales or transfers on the horizon, since timing often changes the tax outcome significantly.
Overview of the legal framework for wealth preservation under cantonal law
Switzerland has no federal inheritance tax. Instead, most cantons levy their own inheritance and gift taxes, with spouses exempt everywhere and direct descendants exempt in most cantons, while more distant or unrelated beneficiaries face higher rates. This cantonal patchwork means two families with identical estates can face very different bills depending on where they are resident and where their property sits.
Property taxation layers a second cantonal system on top. In Valais, the property gains tax, transfer tax, and any municipal supplements are set locally, and the rules on deferral for replacement property follow the cantonal statute rather than a single national rule.
For families with undeclared assets inherited from a previous generation, Swiss tax authorities offer a route back into compliance. The simplified post-taxation of heirs and the penalty-free voluntary self-declaration allow heirs who disclose promptly to settle limited-period liabilities with reduced sanction risk, rather than facing the full historical tax and penalty exposure. Acting early and cooperatively here genuinely changes the outcome, waiting rarely helps.
None of this replaces a conversation with a local notary or cantonal tax office, since the statutes change and local practice varies even within a canton. What families can control is timing: knowing which documents and disclosures are due before a sale, a death, or a gift, rather than scrambling afterwards.
Risks and challenges particular to mountain resort property markets
Property in a resort town like Zermatt carries risks that a city apartment does not. Tourism cycles affect rental income and resale demand, and a slow winter season or a shift in travel patterns can soften values faster than families expect. Mountain real estate also tends to be less liquid than urban property, since the buyer pool is narrower and seasonal.
A sensible response is to avoid treating resort property as a primary store of liquid wealth. Keep it as one asset among several, with a liquid, diversified portfolio sitting alongside it so a slow property market never forces a family into a rushed sale. Building in a cash buffer, as outlined earlier, matters even more for families whose wealth is concentrated in a single holiday property.
Regulatory and zoning changes are another factor worth watching, since cantons and municipalities periodically adjust rules on second homes and foreign ownership, which can affect both value and future transferability. A periodic review with a local notary or tax advisor, rather than a one-off purchase decision, keeps a family’s exposure to these shifts manageable.
Philanthropic options and impact investing as legacy tools
Giving is often treated as separate from wealth preservation, but structured well it does both jobs at once. A donor-advised structure or a family foundation lets a family direct giving over time rather than as a single lump sum, which can also ease the size of a taxable estate depending on the canton and the recipient’s status.
Impact investing, allocating part of a portfolio to sustainability-focused or thematic strategies, achieves something similar within the investment sleeve itself. It keeps capital working toward long-term goals while reflecting values the family wants the next generation to inherit alongside the money.
For families early in this conversation, starting small matters more than starting formally. A modest annual giving plan, reviewed yearly, builds the habit and the governance discipline that a larger foundation would need anyway. It also gives younger family members a concrete way to participate in financial decisions before they inherit full control.
Insurance products relevant to protecting family wealth
Insurance rarely gets the attention estate planning does, but a gap here can undo years of careful planning. Life insurance provides immediate liquidity at the moment it is needed most, covering tax bills or estate costs without forcing a quick property sale. For families with a concentrated asset like a Zermatt property, this liquidity function matters more than usual.
Liability coverage is the other piece worth reviewing, particularly for families who rent out a property seasonally or host frequently. A liability claim tied to a rental guest or a property incident can erode wealth quickly if coverage is thin or outdated.
Reviewing policies alongside the rest of the estate plan, rather than as a separate annual renewal, ensures the coverage actually matches the current asset base and family structure, not the one from five years ago.
Cross-generational communication and education strategies
Wealth preservation plans fail more often from silence than from bad decisions. Families who never discuss the plan with the next generation often find that heirs are unprepared, surprised, or in disagreement at the exact moment clarity matters most.
Regular, low-pressure family conversations about the plan, not just the numbers but the reasoning behind decisions, build the shared understanding that keeps a plan intact across a transition. Involving younger family members in smaller financial decisions early, such as a giving plan or a modest investment account, builds financial literacy before they inherit full responsibility.
This does not require formal family governance meetings from day one. A yearly conversation, perhaps alongside the tax check mentioned earlier, is often enough to keep everyone oriented toward the same goals.
Local professional advisors specialising in family wealth preservation
Families preserving wealth tied to a Zermatt or Valais property typically need three types of professional support, not necessarily from the same firm. A local notary handles binding legal documents, including wills, Erbverträge, and property transfer paperwork, and must be involved for anything notarised under cantonal law. A cantonal or municipal tax advisor, often reachable directly through the local tax office, provides the property-specific calculations on gains tax, transfer tax, and any municipal supplements.
For the investment and coaching side, a FINMA-accredited wealth manager familiar with family-specific planning, rather than a generalist, tends to serve families better, since the regulatory and documentation requirements differ from standard retail investing. Checking a firm’s FINMA status directly, and asking how they coordinate with notaries and tax advisors, is a reasonable first question for any family starting this process.
A closing thought on common pitfalls
Most families lose ground to missing paperwork, not bad luck. Get the inventory and documents sorted before chasing complex structures, and keep family conversations about wealth clear and generous rather than guarded.

FAQ
How is wealth distributed in Switzerland?
The Swiss Federal Statistical Office publishes aggregated wealth statistics showing meaningful concentration among private households, though exact figures vary by canton and by how wealth is measured. These official statistics are the most reliable starting point rather than commonly repeated estimates found elsewhere.
Is Switzerland considered a tax haven?
Switzerland has no federal inheritance tax, and most cantons exempt spouses and, in most cases, direct descendants from inheritance tax, which shapes its reputation for favourable wealth treatment. Whether that qualifies as a tax haven depends on the definition used, and rates still vary considerably by canton and by the beneficiary’s relationship to the deceased.
Is 1 out of 7 people in Switzerland a millionaire?
Specific ratios like this are not something we can confirm from official sources, and figures vary depending on how wealth is measured and which currency is used. The Federal Statistical Office’s wealth statistics are the better reference point for households wanting an accurate picture.
Do Swiss people make a lot of money?
Income and wealth levels vary significantly by canton, profession, and household structure, so there is no single answer that applies nationally. The Federal Statistical Office publishes the official data families can use to understand regional and sector differences.
What is the FINIG authorisation and does my family need one?
Managing third-party discretionary portfolios typically requires a FINIG asset-manager authorisation from FINMA with oversight from a recognised supervisory organisation, while a family managing only its own capital in-house is usually treated differently. Most families working with an external, already-licensed wealth manager like Marmot Finance do not need to pursue this authorisation themselves.
