Wealth tax in Switzerland: taxable assets, deductions and cantonal rates

How Swiss wealth tax works

Unlike income tax, which concerns earnings and other taxable income over a period, wealth tax looks at a stock of assets. Holding savings or investments can therefore create a wealth tax obligation even if you have not sold them.

All cantons levy personal wealth tax under their own rules, together with the relevant communal component. There is no single Swiss rate or uniform tax-free threshold. Tax residence, the municipality and the tax year all matter.

For an ordinary full-year assessment, asset values are generally determined at 31 December. Arrival, departure, inheritance and other changes can require specific treatment. An English-language guide should not be read as importing UK domicile concepts or US tax rules into the Swiss calculation.

Which assets must be considered?

Ordinary household goods and personal effects are generally exempt. High-value collections, art and assets that may be investments need a more careful review under cantonal practice. Do not assume that every item kept at home is exempt.

Assets held in qualifying occupational pension arrangements and tied pillar 3a arrangements are generally outside ordinary taxable wealth while the benefits are not yet payable. Once paid out and held in an ordinary account, the resulting cash generally becomes part of ordinary assets.

A worked net-wealth calculation

This example assumes the listed assets and debts are fully relevant to the same tax assessment. It illustrates the net-wealth calculation before social allowances and does not model intercantonal or international allocation.

The CHF 630,000 is not the tax bill. Apply the relevant allowances, allocation rules and cantonal and municipal calculation to obtain taxable wealth and the resulting tax.

Keep evidence of outstanding debt at the relevant date. Mortgage principal and mortgage interest are different items: principal concerns debt in the wealth calculation, while interest may be relevant to income-tax deductions under separate rules.

Repaying a debt usually reduces both cash and the debt balance. It does not automatically reduce net wealth by the amount paid. Review the whole balance sheet rather than looking at one account in isolation.

Valuing investments and company shares

Use the applicable fiscal values and exchange rates for securities and foreign currencies. A purchase price from several years ago is not necessarily the correct value for the return. Obtain the year-end statements and reconcile all accounts.

For an unlisted Swiss company, the taxable value of your shares is not simply their nominal value. The relevant valuation approach can consider earnings and net assets, with specific treatment for circumstances such as a recent arm’s-length transaction. The Swiss Tax Conference’s Circular 28 and cantonal practice are important references.

If you lend money to your own company, your loan receivable is a separate personal asset from your shares. The corresponding company debt can affect its valuation, but that does not mean the shareholder’s loan can be omitted from the personal return.

Cryptocurrency held at year-end can be relevant even if you have not converted it to francs. Staking, mining or other receipts may also raise income-tax questions. Separate the annual value of holdings from income earned during the year.

Foreign assets and non-residents

Swiss tax residents generally need to disclose their worldwide assets for the assessment. Disclosure does not mean every foreign asset is taxed directly in Switzerland in the same way. Foreign real estate and foreign business assets can fall under allocation rules and still affect the rate applied to assets taxable in Switzerland.

Debts may also have to be allocated across jurisdictions. Simply deducting an entire mortgage from whichever country’s asset produces the best result can be incorrect. Review assets, debts and treaty rules together.

Non-residents can have limited Swiss tax liability because of a Swiss connection, such as real estate. A quasi-resident status or a subsequent ordinary assessment for income-tax purposes does not by itself turn a non-resident into a Swiss resident subject to ordinary worldwide wealth taxation.

For internationally mobile owners, establish residence and the relevant dates first. Then assemble foreign statements and property information rather than assuming those assets are irrelevant to the Swiss return.

Compare cantons on the same basis

A meaningful comparison needs the same tax year, taxable wealth, family status and actual municipality. A headline cantonal rate may exclude communal charges or describe only the highest bracket.

Distinguish the marginal rate on an additional unit of wealth from the average rate on the whole taxable amount. Also check the unit: 1 per mille (1‰) equals 0.1%, not 1%.

• Use net taxable wealth after the applicable allowances.
• Select the actual municipality, not just the canton.
• Check whether a quoted figure includes all relevant cantonal and communal components.
• Use the same household situation and year in each comparison.
• Account for foreign or intercantonal allocations.

Tax shields or limits, where applicable, follow their own formulas and conditions. They are not a universal guarantee that wealth tax cannot exceed the cash income you happened to receive.

Geneva: understanding the 2025 example

The Geneva schedule for tax year 2025 provides wealth allowances of CHF 87,632 for an individual and CHF 175,264 for a married couple assessed jointly, with the applicable family and single-parent rules to be checked. These figures are year-specific, not a permanent nationwide exemption.

This is a separate example from the CHF 630,000 net-asset calculation above. Here, CHF 360,000 is assumed to be taxable wealth after all applicable deductions, and also the amount determining the tax rate. It is not obtained by subtracting an unexplained allowance from CHF 630,000.

From basic tax to the total: City of Geneva, 2025

Assume full-year residence and all relevant wealth allocated to the City of Geneva, before any tax-shield reduction. The 2025 schedules give basic tax of CHF 691.85 and supplementary tax of CHF 26.40.

Budget approximately CHF 1,369, not CHF 718. Figures are illustrative and rounded to cents; official assessment rounding may differ. The supplements shown are calculated on basic tax, not on taxable wealth or on the supplementary tax. This is wealth tax only: income tax and other applicable charges are separate. Another municipality or allocation changes the result.

How Geneva’s tax shield works

Article 60 LIPP can reduce wealth tax when combined cantonal and communal income and wealth taxes, including additional taxes, exceed 60% of the income calculated for the shield. It concerns eligible taxpayers domiciled in Switzerland.

For this calculation, net wealth is deemed to earn at least 1% annually. If actual net investment income is lower, a theoretical return replaces it; related deductions may also need recalculation. Low dividends or interest therefore do not automatically eliminate wealth tax.

The reduction applies to wealth tax. Federal direct tax, the personal tax and supplementary real-estate tax are outside the cap. The CHF 360,000 example cannot establish eligibility without income information. For a married couple living together, both spouses’ figures are combined; cross-border or intercantonal cases require worldwide calculations and allocation.

Illustration: if income determined under the shield rules is CHF 50,000, the 60% comparison threshold is CHF 30,000. That is neither a wealth-tax rate nor a cap on every tax paid.

For property, use the official tax valuation and the adjustments applicable to the property and year. Geneva’s 2025 valuation changes affecting certain villas and condominium properties should not be applied indiscriminately to every property or carried into a later year without checking the assessment.

The practical lesson is to keep three figures separate: gross wealth, taxable wealth after deductions, and the final tax after the full local calculation. Using a basic schedule as if it were the final effective rate understates the bill.

Documents to prepare

• Year-end bank and investment statements, including foreign accounts.
• Cryptocurrency holdings and valuation evidence.
• Property tax valuations and acquisition or disposal details.
• Mortgage and other debt certificates showing principal outstanding.
• Tax valuations of unlisted shares and details of shareholder loans.
• Relevant insurance surrender-value certificates.
• Information on marriage, dependants, moves, inheritances or other changes.

Start with a complete asset inventory, then reconcile it to the previous return. Missing a small foreign account or confusing a shareholder loan with equity can create an incomplete declaration even when the largest assets are correctly reported.
