Key legal question
Whether the employer's lump-sum expense payments of CHF 48,000 for 2008 were fully deductible as professional expenses.
Extracted holding
The taxpayer did not prove the entitlement and reasonableness of the lump-sum expenses; they had to be examined as actual reimbursement of expenses instead.
Extracted reasoning
A lump-sum payment is only fully exempt if based on an approved expense regulation or otherwise substantiated. Here the approved regulation did not provide for lump-sum expenses in the claimed amount.
