In addition to the general Swiss rules on income taxation, the canton of Bern (BE) applies specific cantonal and communal practices that can materially affect the effective tax burden. This page highlights situations in which special rules or allocation mechanisms are particularly relevant, with a focus on mobile individuals, cross-border workers, self-employed taxpayers and property owners.

The information below is descriptive and does not replace the wording of Bern’s tax legislation, federal law, double tax treaties or individual tax rulings. The correct tax treatment in any given case depends on the applicable rules and the taxpayer’s detailed facts.

New Arrivals and Departures

Moving into or out of Bern during the tax year raises questions around tax residency and intercantonal allocation of income and assets:

• Arrival in Bern: Tax residence usually begins when an individual establishes their main place of living in the canton (centre of vital interests), even if ties to another canton or country are maintained.
• Departure from Bern: Tax residence normally ends once the centre of life is moved to another canton or abroad. Bern may retain limited tax rights over certain assets such as real estate located in the canton.
• Intercantonal allocation: For the year of arrival or departure, income and wealth may need to be allocated between Bern and other cantons using federal allocation rules.

Accurate reporting of arrival and departure dates, prior residence and the timing of income is essential to avoid intercantonal double taxation and controversies between tax authorities.

Cross-Canton Workers, Cross-Border Situations and Non-Residents

As a large canton with both urban and rural areas, Bern frequently deals with cross-canton and cross-border cases:

• Residents of Bern working in other cantons or abroad must consider intercantonal or international allocation rules, particularly for employment income and self-employment.
• Non-residents with limited tax liability in Bern (e.g. due to real estate, a permanent establishment or self-employment) are taxed only on Bern-sourced income and assets, although worldwide income may still be relevant for rate-determining purposes.
• Cross-border commuters or individuals with foreign pensions and investment income may fall under specific provisions of double tax treaties, with relief being granted via exemption with progression or tax credits.

The concrete outcome depends on the interplay between Bernese practice, federal rules and the wording of the applicable double tax treaty.

Withholding Tax (Quellensteuer) and Subsequent Ordinary Assessment

Foreign nationals without a permanent residence permit who work in Bern are often taxed at source on their employment income. Important aspects include:

• Mandatory subsequent ordinary assessment if income, wealth or certain other thresholds are exceeded or if additional taxable income is present.
• The possibility of a voluntary ordinary assessment to claim deductions that are not fully reflected in the withholding tax tariff (e.g. significant pillar 3a contributions, childcare costs, substantial professional expenses).
• Changes in personal circumstances (marriage, divorce, acquisition of real estate, change of residence or permit) which can lead to a shift from pure withholding tax to ordinary taxation.

In a subsequent ordinary assessment, federal and cantonal/communal taxes are recalculated as if ordinary taxation had applied for the entire year, with withholding tax credited against the final tax liability.

Investment Income, Dividends and Capital Gains

Bern broadly follows the general Swiss framework for investment income, but cantonal practice still matters:

• Interest and dividends are generally fully taxable as income. Relief mechanisms such as partial taxation may be available for qualifying participations in certain cases.
• Private capital gains on movable assets (e.g. on privately held shares or funds) are usually tax-free for non-professional investors.
• Taxpayers classified as professional securities traders may be taxed on their gains as business income based on criteria such as trading frequency, short holding periods, use of leverage and the relationship between trading and main occupation.
• Capital gains on real estate located in Bern are subject to a separate real estate gains tax with rates that commonly depend on both the gain realised and the holding period.

The distinction between private and professional investment activity is often decisive and can require careful analysis and documentation.

Income from Self-Employment and Partnerships

For self-employed individuals and partners in partnerships active in Bern:

• Business profits are taxed as ordinary income at federal, cantonal and communal level in the hands of the owner or partners.
• Only business-related expenses are deductible; private living costs remain non-deductible, even if settled from business accounts.
• Mixed-use assets (e.g. cars, properties, equipment used both privately and in the business) must be split between private and business use on a reasonable basis.
• Losses can normally be carried forward and offset against future business income within the statutory time limits.

In more complex cases, such as intra-group services, IP structures or cross-border activities, advance discussions or rulings with the tax authorities may be appropriate.

Employee Participation Plans, Bonuses and Severance Payments

Bern hosts a wide range of employers, from local businesses to multinational groups. Special rules may apply to:

• Employee share and option plans, where the timing and valuation of taxable income are governed by federal rules and cantonal practice (e.g. taxation at grant, vesting or exercise, depending on plan design).
• Long-term incentive plans (LTIs), RSUs and other equity-based awards, particularly where the employer or plan is foreign and work is performed in several jurisdictions.
• Bonuses and severance payments, which can in certain circumstances be treated differently from regular salary, especially where they compensate for loss of employment or future income.

International assignments, split-payroll arrangements and cross-border equity plans may require workday-based allocation of income between Switzerland and other countries, as well as consideration of treaty rules.

Pensions and Retirement Income

For residents of Bern, pensions and retirement-related income often involve special considerations:

• Benefits from the 2nd pillar (occupational pensions) and pillar 3a are taxed differently depending on whether they are received as annuities or as lump-sum withdrawals.
• Lump-sum pension payments are generally taxed separately from other income at preferential rates, at both federal and cantonal level.
• Foreign pensions may be taxable in Switzerland, abroad or both, depending on the applicable double tax treaty, with relief provided through exemption or tax credit mechanisms.

For individuals with pension rights in several countries, the timing, form and sequencing of withdrawals can significantly affect their overall tax burden in Bern.

Real Estate in Bern

Ownership and transfer of real estate in Bern are subject to particular tax rules:

• Imputed rental value of owner-occupied property or actual rental income must be declared as income, with deductions generally allowed for mortgage interest and property maintenance according to cantonal guidelines.
• Real estate gains tax is levied on gains from the sale of property in Bern, with progressive rates that often decline as the holding period increases.
• A real estate transfer tax and notarial and land-registry fees may apply when property changes ownership, and these transaction costs should be factored into planning.
• Non-resident property owners can be subject to limited tax liability and filing obligations in Bern, even if they live in another canton or abroad.

For significant property transactions, it is common practice to obtain advance calculations or confirmations from the tax authorities, particularly where reinvestment or major renovations are involved.

International Double Taxation and Relief

Where individuals have income or assets in more than one country, the interaction between Bernese tax law, federal rules and international tax treaties becomes decisive. Typical constellations include:

• Residence in Bern with employment or business activities abroad,
• Foreign investment income and foreign real estate,
• Multiple pensions from different countries.

Relief mechanisms may involve:

• Exemption with progression,
• Tax credit methods, and
• Treaty-specific rules for employment income, pensions, directors’ fees and other income types.

The actual relief granted depends on the exact treaty wording and the taxpayer’s factual situation, including residence status, sources of income and allocation of taxing rights between states.

Practical Guidance

The special rules described on this page show that Bern income taxation becomes particularly complex in situations involving:

• Moves into or out of the canton,
• Cross-canton or cross-border work and residence,
• Withholding tax and subsequent ordinary assessments,
• Self-employment, partnerships and family businesses,
• Property ownership and real estate gains tax in Bern, and
• Foreign pensions and multi-jurisdiction investment structures.

In such cases, personalised advice and, where appropriate, clarification with the tax authorities are often advisable. The other sections of the Bern income tax guide – Rates, Deductions, Filing Requirements and Examples – provide the general framework within which these special rules operate.
