Switzerland: personal tax guide

What the tax system covers

Swiss residents face federal, cantonal and communal taxation within a worldwide framework. Foreign immovable property and business establishments can have exemption and rate-progression consequences. Private gains, professional trading income and cantonal wealth taxes need separate treatment.

When you become tax resident

Swiss federal rules distinguish tax domicile from a qualifying stay. Establishing a home with the relevant intention can create domicile; a stay can also trigger residence after at least 30 days with gainful activity or 90 days without it, subject to the statutory details and exceptions. A generic “under 183 days” plan therefore does not establish non-residence. Immigration permission, municipal registration and the tax analysis are related evidence but different legal questions. The federal, cantonal and communal layers must then be considered together. An ordinary resident’s income and wealth assessment requires treatment of foreign property, businesses and treaty allocation rather than a simple worldwide-total calculation. The destination municipality can materially change the outcome. Before moving, identify the home, work pattern, family connections and foreign taxable assets, and request an analysis for the actual canton and municipality rather than relying on a Swiss national average.

Rates and the tax base

Progressive federal, cantonal and municipal rates. There is no single nationwide combined personal income-tax rate. Select the canton, municipality, household circumstances and income level using the official 2026 schedules. Wealth tax and lump-sum eligibility require separate analysis.

Private investment gains and business trading

Gains on movable assets held privately are generally exempt from federal and cantonal income tax. Cantons tax real-estate gains, and a professional trading activity or business asset is a different category. Securities-trader classification, recharacterized company-sale proceeds and wealth taxation require separate review.

Asset cost basis on arrival

For genuine private movable assets, such as an ordinary private securities portfolio, capital gains are generally exempt federally and in every canton. The map therefore identifies an exemption category, not an arrival-value reset.

Illustration only: a genuinely private share bought for CHF100,000, worth CHF300,000 on arrival and sold for CHF350,000 may produce an exempt Swiss private capital gain. That conclusion depends on the transaction retaining its private-capital character; it does not settle departure-country tax, dividends or wealth tax.

• Private investor status matters. Commercial dealing and business assets fall outside the ordinary private-gain exemption.
• Company owners need a separate sale and restructuring review: transposition and indirect partial liquidation can turn an apparent private share gain into taxable income.
• A wealth-tax value is not a new capital-gains cost basis. Annual valuation, dividends and remuneration are separate questions.

Private capital gains and trading income are different

Gains on privately held movable assets are generally exempt from ordinary income tax, while gains on business assets and professional securities trading can be taxable. The FTA’s Circular 36 addresses the distinction between private investment and professional trading. Frequent transactions, leverage, derivatives, reliance on gains and the wider facts should be reviewed under that guidance; failure to meet a safe-harbour condition is not by itself a substitute for the complete analysis.

Dividends, interest and other investment income are not made exempt merely because a disposal gain is private. Real-estate gains follow their own cantonal system. Cantons and communes also levy wealth taxes, so an investor with low realised income can still have a recurring tax cost. Classify the portfolio, investment activity and legal owner before estimating the benefit. A trading business or a company’s portfolio does not automatically receive the treatment of an individual’s private investments.

Expenditure taxation must fit the actual lifestyle and work

Qualifying foreign nationals may use expenditure-based taxation when settling for the first time or after the required absence and not undertaking gainful activity in Switzerland. Availability and implementation differ by canton. The calculation considers expenditure, statutory minima and a control calculation; it is not a single national annual fee that automatically replaces every tax.

A founder who intends to operate a business from Switzerland must examine whether those duties are compatible. Foreign customers or a foreign payroll do not settle the issue. Treaty relief can require additional income to enter a modified calculation, and Swiss-source property and income remain relevant. Obtain current-year figures for the proposed canton instead of reusing an old federal minimum. Compare the regime with ordinary taxation, including wealth and portfolio classification, and separately secure the appropriate immigration permission. Tax acceptance does not itself grant a residence permit.

Deregistration should reflect a genuine change of residence

Notify the commune through the applicable departure process and preserve the resulting documentation, but do not treat deregistration alone as the entire tax analysis. Establish where the new home and centre of life will be, which accommodation and family links remain in Switzerland and how often the person will return. A temporary period abroad can differ from a permanent move.

Coordinate the departure-year cantonal assessment with the first destination return. The Swiss federal rules distinguish domicile, qualifying stays and economic connections, and the relevant treaty may also matter. Swiss property or business activity can continue to create limited tax obligations after personal residence ends. Keep records of the new residence permission, housing, registrations, travel and work arrangements, so the claimed departure date is supported by facts rather than only an administrative form.

Pension withdrawals need a destination-specific calculation

Departure can affect access to pension capital, but the conditions depend on the pension component, the destination and the relevant social-security rules. Establish whether the proposed withdrawal is available before making tax projections. The official guidance distinguishes ordinary OASI pensions from lump-sum benefits from second-pillar and tied third-pillar institutions; lump sums paid abroad can be subject to Swiss withholding.

A treaty may permit a refund or allocate taxing rights differently, while the destination can impose its own tax. Compare the combined result and the documentation needed for any refund before choosing a payment date. Do not assume an interval between Swiss deregistration and foreign registration creates a tax-free window: residence depends on substantive facts. Keep the pension institution’s written eligibility response, the benefit breakdown, payment date and withholding certificate for both countries’ advisers.

Confirm banking access and continuing obligations before moving

Swiss banks may restrict products or relationships when a client moves to a different country. Discuss the destination with each institution before departure, including access to investments, discretionary management, cards and payment services. Do not rely on retaining an old Swiss address after moving; the account’s tax-residence and due-diligence information must be accurate.

Update tax residence and identification numbers, retain final statements and preserve information needed for foreign account reporting. Review the end or revision of any expenditure-tax arrangement with the canton, together with outstanding returns and Swiss-source income. Immigration permission can also lapse or become affected by departure and prolonged absence, so check that position if returning is part of the plan. The completed departure file should reconcile the tax, pension, banking and residence records rather than handling each as an unrelated address change.

Foreign companies and income attribution

No standalone CFC conclusion is asserted in this draft. Verify current federal law and anti-avoidance, beneficial-ownership and corporate-residence consequences for the arrangement.

Departure, migration and continuing obligations

Article 18(2) DBG treats the transfer of business assets into a foreign business or permanent establishment as a realization event. This concerns business assets and self-employment income, not a blanket departure charge on every privately held investment. Whether assets are private or business is therefore material before a move; a separate company migration can engage the corporate hidden-reserve rules.
