That sentence is true and almost useless.
Because every canton taxes the net wealth of individuals under its own rules, usually with a municipal layer on top.
For someone arriving from a country without an annual net-wealth tax, this can be the biggest surprise in the Swiss calculation.
What is wealth tax?
Wealth tax is an annual tax on net taxable wealth.
Broadly, the calculation starts with taxable assets, deducts qualifying debts and applies cantonal allowances and rates.
The exact rules, thresholds, valuation methods and rates vary by canton.
This is separate from income tax.
You can therefore owe wealth tax in a year when your portfolio produces relatively little taxable income.
What assets are potentially included?
A Swiss resident's wealth-tax return can include categories such as:
- bank deposits;
- listed shares;
- bonds;
- investment funds;
- cryptoassets;
- precious metals;
- private-company shares;
- Swiss real estate;
- foreign real estate for relevant allocation/rate purposes;
- loans receivable;
- cash values of certain insurance arrangements;
- vehicles, boats and other valuable assets where applicable;
- and other taxable property.
The system is based on net wealth, so qualifying debts can reduce the taxable base.
Listed securities
Listed shares and funds are generally valued using official year-end tax values or market values under the applicable rules.
The Swiss tax authorities publish valuation data for a vast number of securities.
That makes the year-end portfolio statement a central tax document.
Private companies
This is where entrepreneurs need to pay attention.
A private company does not have a daily stock-market price, but the shares still need a wealth-tax value.
Swiss valuation practice can use recognised methods based on factors such as earnings and substance value, subject to the applicable rules and circumstances.
A founder who moves to Switzerland with a valuable private company can therefore have significant taxable wealth even though the company pays no dividend.
This is one reason a pre-move valuation matters.
Foreign property
Foreign real estate is generally treated differently from a Swiss bank account.
Tax treaties and Swiss allocation rules can give the property state primary taxing rights, while Switzerland may still take foreign property into account for rate or allocation purposes.
Debt allocation can also become important.
Do not simply remove the foreign house from the Swiss balance sheet because it is abroad.
Swiss property
Swiss real estate is subject to cantonal valuation rules rather than simply taking the estate agent's asking price.
Depending on canton, the taxable value can differ from current market value.
Mortgages can reduce net wealth, but the allocation of debt and interest in an international case should be modelled rather than assumed.
Crypto
Crypto does not disappear from wealth tax because it is decentralised.
Swiss residents generally need to declare cryptoassets at the relevant tax value.
The tax authorities publish year-end values for major cryptocurrencies; other tokens require an appropriate valuation approach.
A large crypto holder should keep year-end wallet and exchange records.
Debt: why leverage matters
Wealth tax applies to net wealth, not gross assets.
That makes genuine deductible debt relevant.
But borrowing CHF 10 million does not automatically reduce Swiss taxable wealth by CHF 10 million in every international fact pattern. Asset and debt allocation rules can matter, particularly with foreign real estate and cross-border assets.
There is no single Swiss wealth-tax rate
Each canton has its own system.
The municipality can then change the final burden further.
Some cantons are deliberately attractive to wealthy residents. Others impose materially higher recurring wealth tax.
This is why an HNWI should never choose a canton from an income-tax comparison alone.
Compare Swiss cantons
Worked illustration: why the canton matters
Assume a new resident has:
- CHF 20 million listed portfolio;
- CHF 4 million private-company interest;
- CHF 3 million Swiss home;
- CHF 2 million mortgage;
- CHF 500,000 cash;
- no other material debt.
The starting economic net worth is approximately CHF 25.5 million before applying Swiss tax valuation rules, exemptions and allocations.
Even a seemingly small difference in effective wealth-tax burden can become meaningful on that base.
At an illustrative 0.20%, CHF 25 million produces CHF 50,000 a year.
At an illustrative 0.60%, it produces CHF 150,000.
Those percentages are examples, not quoted canton rates. The point is the scale.
For a HNWI, basis times rate matters more than whether the percentage looks small.
Wealth tax and income tax interact in the real decision
Suppose Canton A saves CHF 80,000 of income tax but costs CHF 50,000 more in wealth tax than Canton B.
The real annual advantage is CHF 30,000 before considering housing, property and other differences.
This sounds obvious, yet many relocation comparisons quote only marginal income-tax rates.
What about lump-sum taxation?
A qualifying foreign national under expenditure-based taxation is taxed under the special regime rather than simply being assessed like an ordinary taxpayer on worldwide income and wealth.
Cantonal rules and the statutory control calculation remain important.
For a HNWI, the correct comparison is therefore:
ordinary income + wealth taxation in several cantons versus the available expenditure-based arrangement.

Trusts, foundations and similar structures
International wealth structures need separate analysis.
The Swiss tax treatment can depend on legal form, revocability, control, beneficiary rights, settlor status and the actual facts.
A Liechtenstein foundation, trust or foreign holding company should not be assumed to sit outside the individual's Swiss tax position merely because legal title is elsewhere.

Married couples
Swiss taxation of married couples involves joint elements that can affect income and wealth taxation.
The family structure should therefore be included in the canton model.
This is particularly important where spouses own assets separately under foreign matrimonial-property rules or where only one spouse initially moves.
Inheritance planning
Wealth tax is annual. Inheritance and gift taxes are event-driven.
Switzerland has no federal inheritance tax, but cantonal rules differ.
For a family planning a permanent move, the canton that looks slightly cheaper each year may not be the best long-term answer if succession rules are ignored.
US citizens
Americans face an unusual combination.
Switzerland can impose annual wealth tax while the United States continues citizenship-based income and reporting obligations.
The Swiss wealth tax does not simply replace a US tax, and foreign-tax-credit treatment needs specific advice.
Portfolio construction also needs to account for US rules such as PFIC taxation.

UK movers
A UK mover may be unfamiliar with an annual wealth tax, but should also keep the UK departure and temporary non-residence rules in view.
A Swiss wealth-tax calculation cannot be separated from the question of whether the UK still taxes particular income, gains or assets.

What to prepare before moving
For a serious pre-move wealth-tax model, gather:
- bank and brokerage statements;
- private-company financials and recent valuations;
- property values and mortgages;
- crypto holdings;
- loans made and received;
- insurance policies with cash value;
- trusts, foundations and holding structures;
- marital-property information;
- pension assets;
- planned Swiss home and financing.
Then run the same fact pattern through the cantons and municipalities you are genuinely considering.
The planning opportunity
Wealth tax is not a reason to avoid Switzerland.
It is a reason to choose Switzerland intelligently.
A wealthy resident can often change the recurring burden substantially through canton and municipality selection, legitimate debt, ownership planning and choosing between ordinary and special tax regimes where eligible.
But these decisions are easiest before residence begins.
The question to ask
Do not ask:
"What is the Swiss wealth-tax rate?"
Ask:
"What will my assets be worth for Swiss tax purposes, what debt is recognised, and what will I pay in each canton I would actually live in?"
That is the calculation that matters.
