What is the difference between federal, cantonal and municipal tax?

In Switzerland, income taxes are divided into three levels. The federal direct tax (IFD) is set by the Confederation and is the same in all cantons. Cantonal tax varies from canton to canton, and the Outer Appenzell Canton has its own rates. Finally, the municipal tax is calculated by applying a multiplier to the cantonal value, so that two different municipalities in the same canton have different final rates. All three contribute to the total tax burden.

How do municipal multipliers work in the Outer Appenzell Canton?

Each municipality of the Canton of Appenzello Outer applies a multiplier to the value of the cantonal tax. For example, if the cantonal base is 100 CHF and the multiplier of your municipality is 1.15, the municipal tax due is 115 CHF. This means that different municipalities have different tax burdens. The specific multiplier of your municipality can be consulted on the portal of the cantonal tax administration.

What are the main deductions from taxable income?

Common federal deductions across Switzerland include: mandatory and optional AVS/AI contributions, contributions to pension funds (LPPs), interest on mortgage debt, LAMal health insurance premiums, contributions to foundations, donations.

Operational details

Practical analysis: scenarios and contributions

Let's assume a hypothetical scenario: an employee residing in the Outer Appenzell Canton with gross income of CHF 80'000 per annum. Compulsory social security contributions, which reduce the net income on which the DFI is calculated, are deducted from the gross:

AVS/AI/IPG: 5.3% to be paid by the employee (corresponding to 10.6% total between employee and employer)
Unemployment insurance (AD): 1.1% up to an annual maximum
Non-occupational accident insurance (LAINF): 0.7–1.5% according to the sector of activity

If the worker is subject to a pension fund (LPP/BVG), additional progressive contributions are added by age group: 7% for 25–34 years, 10% for 35–44 years, 15% for 45–54 years, 18% for 55+ years up to the reference age.

Federal and Cantonal Deductions

After calculating the net income from social security deductions, the allowable deductions are applied: LPP contributions (pension fund), interest payable on mortgage loans, LAMal premiums (health insurance), optional AVS contributions for self-employed, donations to public utilities, medical expenses not covered by insurance. You can estimate your tax burden using our calcolatore imposte. The resulting federal taxable income is subject to the IFD federal tax progression.
