20 municipalities and the unit system

Appenzell Ausserrhoden has 20 municipalities. The simple tax is multiplied by the total of the tax multipliers of the canton (3.30 units in the 2025 tax year), the municipality and the parish. The communal tax multipliers range from 2.60 (Teufen) to 4.50 (Trogen) – without church, this gives totals between 5.90 and 7.80.

In 2023, voters rejected a reduction to three to five municipalities – the 20 municipalities with their differing tax multipliers remain. What counts for your tax return is the municipality of residence at the end of the year.

The tax portal – fully digital with AGOV

Ausserrhoden works paperless: via the cantonal portal mein.ar.ch with AGOV login, the tax return can be filed fully digitally – including electronic attachments, deadline extension and access to the tax account.

The portal is an option for anyone who wishes to complete the return themselves. If you want to be sure that every item is recorded correctly and completely, we take care of it for you: we enter your details, discuss the draft with you and prepare the submission.

Typical mistakes that cost Ausserrhoden taxpayers money

In practice, we see the same points again and again: the high third-party childcare deduction of up to CHF 25'000 is not fully used. The graduated child deduction is calculated with the wrong age band. Repeated deadline extensions cost CHF 25 each, even though early planning avoids this.

The insurance deduction with the child supplement of CHF 1'000 also often remains unused. A specialist checks every item individually and points out missing receipts to you before the return is filed.

Withholding tax

Withholding tax in Appenzell Ausserrhoden

If your salary is taxed directly at source, an ordinary tax return is not automatically required – but in certain cases it is mandatory or possible on a voluntary basis.

01

Who is subject to withholding tax?

In principle, foreign employees without a C settlement permit who are resident or staying in the canton – for example with a B or L permit. The cantonal tax administration in Herisau is responsible.

02

NOV – subsequent ordinary assessment

From a gross annual income from employment of CHF 120'000, the subsequent ordinary assessment (NOV) is mandatory; for married couples, the incomes are not added together. Below that, it can be requested voluntarily – by 31 March of the following year; thereafter it remains in place until the end of the withholding tax liability.

03

How we support you

We check the tariff code, marital status, other income and possible deductions and assess whether a NOV is worthwhile in your case. We then submit the application on time and prepare the complete tax return.

This information is for guidance only and does not replace an individual assessment. We review your specific situation before we start processing.

Typical situations in Appenzell Ausserrhoden

Commuting to St. Gallen

Teufen, Speicher, Trogen: many residents of Ausserrhoden work in the city of St. Gallen. What counts for the tax return remains the place of residence. The travel expense deduction is capped at the cantonal level at CHF 6'000 per year (2025 tax year).

Big differences between 20 municipalities

Teufen (total tax multiplier 5.90 without church) and Trogen (7.80) are almost a third apart – for identical income. The merger reform rejected in 2023 has not changed this: there remain 20 municipalities with their own tax multipliers.

Families with childcare

Ausserrhoden allows third-party childcare costs of up to CHF 25'000 per child – almost the federal level. The child deduction is graduated by age: CHF 5'300 up to 4 years, CHF 7'400 up to 15, CHF 11'600 from 15 or in education (2025 tax year).

Going digital

Ausserrhoden is one of the most digital tax administrations: the tax return runs entirely via the cantonal portal mein.ar.ch with AGOV login – including attachments, deadline extension and tax account. We prepare everything so that the submission goes smoothly.

Property and imputed rental value in Appenzell Ausserrhoden

Anyone who owns residential property in Appenzell Ausserrhoden is taxed on the imputed rental value as income and can in return deduct mortgage interest, maintenance and administration costs. The key is a clean separation: repairs and replacements preserve the value and are deductible; an extension increases it and is not.

Whether a detached house in Teufen or a farmhouse in the Hinterland: we carefully compile the maintenance costs – lump sum or actual, depending on what is more favourable for your tax year.

If your property is located in another canton or you own several properties, a tax allocation is made between the public authorities involved. We record all properties in full.

  • Imputed rental value and property details recorded correctly
  • Mortgage interest and list of debts checked
  • Maintenance: value-preserving separated from value-adding
  • Lump-sum or actual deduction compared
  • Properties outside the canton taken into account

Additional service: CHF 65.– per property.
