Question juridique clé
Whether the Vaud degressive mileage forfait applied to federal direct tax violates equal treatment.
Solution extraite
The canton’s use of a degressive mileage table for federal direct tax is compatible with equal treatment because the scheme is allowed by the federal ordinance, serves practicability, and any disparities are limited and offset by the option to prove actual expenses.
Motifs extraits
Art. 26 LIFD permits forfaits; Art. 5 para. 4 of the ordinance allows cantons to set staggered deductions. The resulting differences are a tolerated consequence of tax practicability and are not systemically excessive.
