GRP Rainer Lawyers and Tax Advisors, Cologne, Berlin, Bonn, Bremen, Düsseldorf, Essen, Frankfurt, Hamburg, Hanover, Munich, Nuremberg, Stuttgart and London www.grprainer.com/en explain: The claimants desired that various expenses be taken into account for tax purposes. When the tax office did not comply with this desire, they initially lodged the necessary appeal, yet it was dismissed by the tax office as unfounded. In the information on available legal remedies, it was pointed out to them, among other things, that the claim was to be submitted in writing to the Court. According to the law, written form can in principle be replaced with electronic form, yet this requires a qualified electronic signature as defined by the German Digital Signature Act.
