Tax return Obwalden: which documents, which portal?
The short answer
The tax return for individuals goes through eTax OW / eSteuerportal; the responsible body is the cantonal tax authority (Steuerverwaltung Obwalden). The canton publishes no blank form — you get the ordered dossier and the direct route into eTax OW / eSteuerportal. The canton sets the filing deadline – what counts is the information from the tax authority.
