In
Switzerland, generally speaking, all registered residents are also deemed to be tax-resident in Switzerland and are thus taxed there on their entire worldwide income and wealth, except on the income and wealth from foreign business or real estate or where
tax treaties limit double taxation. For tax purposes, residence may also arise if a person stays in Switzerland for 30 days, or for 90 days if he or she does not work. Either a
progressive or
proportional income tax is levied by the Confederation and by the cantons on the
income of
natural persons. The income tax is imposed as a
payroll tax on foreign workers without a residence permit, and in the form of a
withholding tax on certain transient persons, such as foreign musicians performing in Switzerland. Taxable income includes all funds accruing to a person from all sources, in principle without deduction of losses or expenses, and usually including the rental value of a house lived in by its owner. Non-working foreigners resident in Switzerland may choose to pay a
lump-sum tax instead of the normal income tax. The tax, which is generally much lower than the normal income tax, is nominally levied on the taxpayer's living expenses, but in practice (which varies from canton to canton), it is common to use the quintuple of the rent paid by the taxpayer as a basis for the lump-sum taxation. This option contributes to Switzerland's status as a tax haven and has induced many wealthy foreigners to live in Switzerland. ==In Russia==
