  • Nonresident entities with a taxable nexus in Appenzell A.Rh. (e.g., a permanent establishment or AR-situs real estate) generally file a limited cantonal return covering their local taxable base.
  • All legal forms treated as “juristic persons” (e.g. AG, GmbH, Genossenschaft, certain foundations and associations) normally file even in loss years or where only minimum capital tax is due.
  • One return per legal entity. Groups file separately per entity registered in Appenzell A.Rh.; group information is provided via attachments (e.g., transfer pricing and intercompany documentation) rather than a consolidated return.

Appenzell Ausserrhoden operates a cantonal Steuerportal at esteuern.ar.ch for (online) filing and for requesting Fristerstreckungen (extensions) for both natural and juristic persons.

Deadlines & Extensions

Standard timing (ordinary due date)

In Appenzell Ausserrhoden, the filing package / official forms show the due date for returning the corporate tax return. For example, the cantonal juristic-person forms for tax period 2024 indicate a submission deadline of 30 June 2025.

Always follow the due date printed on the filing notice or on the current-year cantonal forms for your company’s tax period. If you have an AR tax nexus but have not received filing information, contact the cantonal tax administration to clarify registration and deadlines.

Extensions (Fristerstreckung via Steuerportal)

If you need more time, request an extension before the printed due date via the AR Steuerportal (esteuern.ar.ch). The portal supports extension requests for juristic persons and also mass extensions (e.g., for trustees handling multiple entities).

An extension to file does not automatically extend the time to pay; interest may accrue on unpaid balances even where the filing deadline has been extended. If you need instalments or expect a late payment, contact the tax office proactively.

Assessment, Payment & Interest

  • Assessment. After the return is processed, the cantonal tax administration issues the assessment covering cantonal and communal components (and direct federal tax where applicable), including capital tax.
  • Advance payments. Companies typically receive provisional invoices/instalments based on prior years or estimates; these are credited against the final assessment.
  • Payment mechanics. Pay using the references indicated on invoices/assessments (e-banking, QR-bill, etc.) to allocate payments to the correct tax period.
  • Interest & penalties. Interest is normally charged on late payments; penalties may apply for late filing or incomplete disclosure.
  • Objections/appeals. The assessment letter specifies objection deadlines and procedure; objections should be filed in writing with supporting evidence.

Tax Clearance & Commercial Register (Corporate Changes)

  • Corporate events such as dissolution, liquidation, mergers, de-mergers, or seat migrations often require tax coordination/clearance before commercial register steps are completed.
  • For liquidations, the tax office typically assesses taxes up to the liquidation date and may require interim/final returns; distributions can trigger additional income or withholding tax consequences.
  • In seat relocation cases (to/from Appenzell A.Rh.), coordinate tax opening/closing balance sheets and allocate hidden reserves and equity between cantons.
  • For restructurings under Swiss tax neutrality rules, advance tax rulings are frequently used to secure cantonal and federal treatment.
