Pod obrtom se podrazumijeva registrirana djelatnost u skladu sa Zakonom o obrtu. Porez na dohodak je specifičan zbog svog socijalnog obilježja. U teoriji je poznat pod imenom najsocijalniji porez jer se ne obračunava na egzistencijalni minimum poreznog obveznika koji se određuje u visini osobnog odbitka poreznog obveznika te uzdržavanih osoba.
