Question juridique clé
Whether the health-insurance deduction had to be reduced by the full subsidy amount of CHF 11,280 or only by the amount actually received by the taxpayers.
Solution extraite
Only the subsidy actually received by the taxpayers was relevant; the deduction had to be reduced only by CHF 7,008, increasing the deductible insurance costs by CHF 2,883.
Motifs extraits
Taxable income requires an actual accretion of wealth. Only amounts that actually flowed to the taxpayers count taxably; social-insurance calculation rules for family members did not justify taxing more than the amount actually received.
