Questione giuridica chiave
Whether tariff D for secondary employment applied to the taxpayer's 2007 withholding tax
Decisione estratta
Tariff D was not justified because the taxpayer had no proven secondary employment but rather a modest main employment without replacement income.
Motivazione estratta
A proportional tariff is only justified for true secondary employment or equivalent replacement income; a bare presumption from low hours and income can be rebutted, and the authorities had not clarified any additional income.
