Question juridique clé
Whether computer hardware and related home office costs for a canton school teacher are deductible as professional expenses.
Solution extraite
Such costs are deductible to the extent they are necessary for unimpeded professional preparation and not private; a 50/50 split between business and private use was उचित here.
Motifs extraits
Teachers need computer access for preparation, internet research, and didactic use. Because the school did not provide an adequate workplace with a PC, home equipment became professionally necessary. Given mixed private use and lack of exact proof, apportionment was appropriate.
