Appealing against a tax-related decision
You can appeal against a decision or ruling made by the Tax Administration, the Assessment Adjustment Board or the Administrative Court.
To appeal against a decision made by the Tax Administration, file a claim for adjustment with the Assessment Adjustment Board. You can find the appeal deadlines and other necessary information in the instructions for appeal, enclosed with each tax decision.
Advance rulings issued by the Tax Administration can be appealed directly to the Administrative Court.
To appeal against a decision made by the Assessment Adjustment Board, file an appeal with the Administrative Court. A decision by the Administrative Court can be appealed to the Supreme Administrative Court if the Supreme Administrative Court grants a leave for appeal.
