Short Answer
Any verifiable out-of-pocket expenditure incurred to secure or maintain your current employment income can be legally subtracted from your overall taxable calculation as a Werbungskosten item. The state applies a flat automatic deduction of 1,230 € to every single worker's profile before evaluating individual itemized lists.
What Most Expats Don't Realize
You purchased an expensive work laptop, professional textbooks, and dedicated office furniture out of your pocket during your first year of German employment. You did not track your precise commuting distances or home office dates because you assumed the automatic standard allowance covered everything you spent. You missed out on itemizing your massive operational total, which surpassed the threshold and cost you a direct loss of 450 € in potential cash refunds.
What To Do
- Open an electronic spreadsheet to log every individual calendar day you spent working entirely from home.
- Print out the physical purchase invoices for your professional gear, electronics, and job-related insurance policies.
- "Ich mache meine berufsbedingten Umzugskosten als Werbungskosten geltend." (I am claiming my job-related relocation costs as income-related expenses.) — list your moving receipts inside the designated section of your annual tax form.
The Truth
In the German view, you shouldn't be taxed on money you had to spend just to be able to work. It is the cost of doing business applied to individuals.
