Questione giuridica chiave
Whether alimony and child maintenance paid only from September 2003 may be deducted for the whole 2003 tax year.
Decisione estratta
Only the amounts actually due and paid after separation, from September 2003 onward, are deductible; amounts supporting the family before separation are not deductible.
Motivazione estratta
Under the LIFD and harmonized cantonal rules, family expenses during the common household are nondeductible; deductibility begins with separation and the shift to taxable maintenance payments.
