The 1st Section of the Superior Court of Justice (STJ) allowed the State treasuries to arbitrate the basis for calculating the Causa Mortis and the Transfer of Donations Tax (ITCMD), which is levied on inheritances and donations, when they do not agree with the value of the property indicated by the taxpayer. The new value set must, however, be determined through an individual administrative process, in compliance with the legal and adversarial procedure. The tax authorities must still prove why the amount indicated by the taxpayer would be outside the market value.
