Tax Deductions for Private Individuals in Switzerland

Tax deductions are a key instrument for reducing tax liability. They allow specific expenses to be deducted from taxable income. In Switzerland, a wide range of deductions exists covering various areas of life.

 

Income Tax Deductions

Tax Allowances

Tax allowances reduce taxable income before tax is calculated. Their amount depends on the canton and personal circumstances such as marital status and number of children.

 

Professional Expenses

Professional expenses include commuting costs, meals, work equipment, and further education. Business travel and work-related accommodation costs may also be deductible under certain conditions.

 

Social Security Deductions

AHV, IV, and EO Contributions

Mandatory contributions to AHV, IV, and EO are fully deductible and reduce taxable income.

 

Unemployment Insurance

Contributions to unemployment insurance can also be deducted and provide both tax relief and social security.

 

Family Deductions

Child Deductions

A cantonally defined amount can be deducted for each child. In addition, childcare and education costs may be deductible.

 

Spouse Deduction

Married couples may claim a spouse deduction, which reduces their joint taxable income.

 

Education and Further Training

Education Costs

Costs for education and training may be tax-deductible under certain conditions, both for oneself and for children.

Medical costs not covered by health insurance may be deducted if they exceed an income-related threshold.

 

Disability-Related Expenses

Costs for aids, care, or structural adaptations related to disability are tax-deductible.

Mortgage Interest Deductions

Mortgage interest for owner-occupied property can be deducted from taxable income.

 

Rent Deductions

In certain cantons, rent or parts of it may be tax-deductible.

 

Retirement Provision and Savings

Pillar 3a

Contributions to Pillar 3a are tax-deductible and directly reduce taxable income.

 

Securities Losses

Losses from securities transactions may be offset against gains and thus reduce tax liability.
