Questione giuridica chiave
Whether the 2007 loss carryforward had to be increased by the real estate value increase so that the 2008 cantonal profit tax would be reduced to zero.
Decisione estratta
No. The cantonal authority in GR correctly took the operating loss, the property gain, and prior losses into account; after intercantonal allocation no remaining amount justified increasing the 2007 loss carryforward.
Motivazione estratta
In an intercantonal enterprise, the property canton must absorb operating losses, but only the remaining property gain is attributable to it. The 2007 zero assessment did not finally determine the amount of the future loss carryforward, but the applicable allocation rules did not require adding the full real estate value increase to the loss carryforward.
