Can I claim a home office deduction in Switzerland?

Maybe, but only if you meet specific conditions. In Switzerland, a home office deduction is generally only available if your employer does not provide you with a suitable workspace and you have a room used exclusively as your office. If your employer provides a workplace, including shared desks with sufficient availability, you may not qualify. It's also important to compare the home office deduction with the standard professional expense deduction, as claiming one may reduce or replace other deductions such as commuting and meal allowances.
