Regulations: Arts.14.1b) Law IRPF and 7 Regulation IRPF ; 11.1 and 3.1 LIS
The Personal Income Tax Law establishes as a basic guiding principle in this matter the reference to the regulations governing Corporate Tax, without prejudice to certain specialities contained in the tax Regulations themselves.
According to article 11.1 of the IS , the general criterion for tax imputation is constituted by the accrual principle, according to which income and expenses derived from transactions or economic events will be imputed to the tax period in which their accrual occurs, in accordance with accounting regulations, regardless of the date of payment or collection, respecting the due correlation between them.
