The appellant A. [X.] , a German national, has been living in the canton of Obwalden for years, while his wife B. [X.] lives in Hamburg and cares for her disabled mother. The tax administration of the canton of Obwalden assessed the appellant for the state and municipal taxes 2001 with a taxable income of CHF 14'900.-- and for the direct federal tax 2001 with a taxable income of CHF 19'600.--. The tax administration took into account the income of the wife, which it determined at its discretion, since the appellant had not provided any information about it.

The appellant lodged an objection against the tax assessment decisions, which were rejected by the tax administration.

The appellant now requests that the judgment of the Administrative Court be overturned and the matter be referred back to it for a new decision and new tax assessment. He argues that his wife's income should not be taken into account for determining the taxable income.

The court concludes that the lower court…
