Facts and figures
Pre arrival procedures

The employer is required to apply for a residence and work permit prior to the employee taking up employment in Switzerland. It is therefore important that the expatriate’s employment contract and benefits package is structured in a tax-efficient manner before filing the application.

Employment visas

Employment of non EU/EFTA citizens

Switzerland imposes strict regulations on foreign employees. Each year, the federal authorities review the numbers of work permits that may be issued. In particular, the applicant employer must demonstrate that in spite of all its efforts it was unable to find a suitable person on the Swiss or EU/EFTA labor market.

However, these rules are applied less rigorously for executives or qualified specialists of internationally operating firms within the scope of an intercompany transfer and for executives or highly qualified specialists who are indispensable for important research projects or essential for the fulfillment of extraordinary assignments.

Employment of EU/EFTA citizens

One of the numerous agreements signed between Switzerland and the EU is the agreement on the free movement of persons (including recognition of professional diplomas), entered into force on 1 June 2002. Similar rules are applicable to Iceland, Norway, Liechtenstein (EFTA countries).

Tax year

The Swiss tax year runs from 1 January to 31 December.

Swiss taxpayers as well as foreign holders of a permanent residence permit (C permit granted after five or ten years of residence depending upon the nationality) are required to file an annual tax return. For foreign holders of a B permit (one year for non-EU/EFTA citizens, five years for EU/EFTA citizens) or an L permit (duration of less than one year), then the tax on salary is collected at source and paid by the employer. If a foreign holder of a B or L permit has an employment income of gross CHF 120’000 or higher per year (relevant bracket for most cantons) and if the person is an unlimited Swiss tax resident, a tax return must be filed as well. In case a foreign holder of a B or L permit has an employment income of less than gross CHF 120’000 and wants to claim additional deductions a voluntary tax return filing can be requested until 31 March of the following year.

The personal tax return should normally be filed as of 31 March following the end of the tax year concerned. Depending on the canton of residence an extension of the filing deadline beyond 31 March is possible.

Income tax rates

Swiss tax residents are subject to federal, cantonal and communal taxes. If registering with a religious affiliation for the catholic or protestant church, Swiss residents are required to pay church taxes as well. The taxable income is subject to a progressive scale and the tax rate is determined on the basis of the Swiss resident’s worldwide income and net wealth.

For a single person with no children, the global rate calculated on a gross income of CHF 150,000 could vary between 12% and 24%, depending on the place of residence.

For a married person with no children, the global rate calculated on a gross income of CHF 150,000 could vary between 8% and 16%, depending on the place of residence.

Basis of taxation
Residence and domicile

Individuals are subject to unlimited Swiss taxation (worldwide income and wealth except foreign business and immovable property) when they are a resident in Switzerland. Individuals are considered a tax resident based on Swiss domestic law:

  • either because they are ‘domiciled’ in this country (intention of remaining on a long term basis);
  • or because they are ‘resident’, ie they remain in Switzerland without any significant interruption for at least 30 days with a gainful activity (at least 90 days without a gainful activity).
Income from employment

Assessable employment income includes all wages, salaries, overtime pay, bonuses, gratuities, perquisites, benefits, tax gross-ups, etc.

The expatriate’s employer is required to deduct and retain the tax at source from the assessable employment income.

The taxation at source applies to most expatriates moving to Switzerland. The basic principle is that expatriates are subject to wage source tax if they do not have a C permit. However, they must also file an ordinary tax return if their annual gross salary exceeds a certain amount (usually CHF 120,000) or if they have other sources of taxable income.

Source of employment

As mentioned above, where duties are performed in Switzerland, any remuneration received in respect of these duties is subject to Swiss income tax regardless of the expatriate’s tax residence status (subject to the relevant Double Taxation Agreement (DTA)).

Benefits (in kind)

In general, where a benefit is enjoyed in Switzerland, a Swiss income tax charge will arise. Therefore, housing, meal allowances, provision of a car, and relocation allowances will be considered for income tax purposes in addition to the individual’s salary.

Relief for foreign taxes

Where no DTA applies, double taxation on foreign source income is in principle alleviated by means of the deduction method (foreign tax deducted from the taxable income).

Where a DTA exists, double taxation is in principle eliminated in accordance with the exemption method.

However, the credit method is utilized for dividends, interest and, sometimes, royalties derived by Swiss residents from another contracting country: Under the credit method, the foreign tax at source is credited against Swiss taxes, however, the credit may not be higher than the amount of Swiss taxes on such income. A so-called lump tax credit mechanism has been enacted for this purpose.

Deductions from income

Certain expenses can be provided by an employer free of income tax where they qualify as wholly, exclusively, and necessarily incurred in the performance of the employment duties.

Personal tax deductions apply to Swiss tax residents and are based on their personal tax circumstances.

Individuals qualifying as expatriates for Swiss tax purposes are entitled to special deductible expenses (directly related moving expenses, reasonable housing costs in Switzerland if a permanent residence is kept in the country of origin and kept permanently available for personal use (not rented out), schooling expenses in the native language (unless the Swiss public school system already provides class in the native language)).

These deductions are only admitted provided they are not reimbursed by the employer. In order to qualify as an expatriate an employee must either be a senior executive or a specialist with special professional qualifications who is assigned to Switzerland by his foreign employer for a limited period of up to five years. The Swiss authorities are strict in regard to acceptance of expatriate deductions and usually require a lot of additional documentation to assess if an individual is considered an expatriate for Swiss tax purposes.

Other taxes
Capital gains tax

Capital gains on movable private (not business) assets are generally exempted from income tax. Capital gains on immovable property are generally subject to a separate real estate capital gains tax.

Inheritance, estate and gift taxes

These taxes are levied (only at cantonal and communal levels) if the deceased/donor is Swiss resident (also on immovable properties situated in Switzerland). The rates are progressive and depend on the degree of relationship between the deceased/donor and the heir/donee. However, no tax is levied between spouses and, in many cantons, between parents and descendants. Moreover, the respective DTAs must be considered in an international inheritance context.

Investment income

Investment income such as interest, dividends, etc. is subject to Swiss income tax.

Real estate tax

Depending on the municipality of residence, real estate taxes are levied on a cantonal and/or municipal level.

Social security taxes

The Swiss social security system is based on the so-called ‘three pillars’.

  • The 1st pillar: Old age and survivor insurance (AVS/AHV) and disability insurance (AI/IV), with the objective to meet the basic needs of retirees, survivors and disabled individuals. Individuals with gainful employment in Switzerland are required to contribute. The total contribution is currently 10.6% of total employee remuneration. Half of it is paid by the employer and the other half (5.3%) is paid by the employee.
  • The 2nd pillar: Company pension plan, with the objective to maintain the individual’s standard of living after retirement. Individuals with gainful employment in Switzerland are required to contribute. Total contribution varies according to the age of the person and the scheme chosen by the company. The cost for a minimal pension plan amounts to about 20% of the total employee remuneration. At least half of it is paid by the employer and the remaining portion by the employee
  • The 3rd pillar: Private pension funds, with the objective to build up private capital. This is encouraged by tax exemptions but is not required.

Individuals with gainful employment in Switzerland are also required to contribute to unemployment insurance.
The total contribution is 2.2% of the employee remuneration, capped at CHF 148,200, per year. Half of it is paid by the employer and the other half (1.1%) by the employee.

However, if certain conditions are met, expatriates generally remain affiliated to the social security system of their own country (for EU/EFTA citizens Form A1 and for many other countries Certificate of Coverage).

Stock options


Monetary benefits deriving from employee shares are generally taxable as employment income at the time the shares are granted/vested.

For restricted shares, the market value is reduced according to the number of years the shares are blocked. The discount amounts to approx. 6% per blocked year on the market value of the share and is applicable to a maximum of ten years.


Monetary benefits deriving from employee options that are traded at the stock exchange are taxed at the time of granting.

Options that are not traded at the stock exchange or restricted are taxable at the time they are exercised. The taxable benefit corresponds to the difference between the market value of the share at exercise date and the exercise price.

Wealth tax

Wealth tax on the cantonal and communal level is assessed on net assets. The rates, subject to a progressive scale, are typically in the range of 0.1%-1%.

Other specific taxes

Church tax is levied on a cantonal/municipal level as a percentage/multiplier of the taxable income and net wealth.

Tax planning opportunities

Where foreign employment continues to exist and part of the expatriate’s duties are performed outside of Switzerland, any employment income received in respect of the foreign duties will be treated in accordance with the DTA.

A significant part of tax planning involves the effective structuring of employment arrangements. Grant Thornton’s tax team can advise expatriates on these and related opportunities.
