Comprehensive Guide on How to File a Tax Return in Germany

Filing a tax return in Germany can seem overwhelming, especially for expats and first-time filers. However, understanding the system can help you maximize your refund and avoid penalties. The German tax system is designed to be fair and efficient, ensuring that individuals contribute according to their income levels while also benefiting from deductions and allowances.

Whether you’re an employee, freelancer, or investor, knowing the rules can save you money and prevent legal issues. This guide walks you through the entire process, from determining whether you need to file to submitting your return efficiently.

Understanding the German Tax System

Income Tax in Germany

Germany operates on a progressive tax system, meaning the more you earn, the higher your tax rate. Income tax (Einkommensteuer) applies to various sources, including employment income, self-employment income, rental income, and investment gains. Employers deduct income tax at source for salaried employees, while freelancers and self-employed individuals must file their taxes independently.

Progressive Tax Rates

The German income tax brackets (as of 2024) are structured as follows:

Up to €11,604: Tax-free (basic allowance)
€11,605 – €62,810: 14% – 42% (progressive rates)
€62,811 – €277,825: 42% (higher income bracket)
Above €277,826: 45% (top earners)

This system ensures that lower-income individuals pay a smaller percentage of their earnings in taxes, while high earners contribute more.

Additional Taxes

Apart from income tax, other taxes may apply, including:

Solidarity Surcharge (Solidaritätszuschlag): A 5.5% additional tax for high earners.
Church Tax (Kirchensteuer): Ranging from 8-9% for members of registered churches.
Value Added Tax (MwSt): A consumption tax of 19% (standard) and 7% for essential goods.

Who Needs to File a Tax Return?

Certain individuals are required to file a tax return, including:

Self-employed individuals and freelancers.
Those who earned more than €410 from side jobs or rental income.

Understand freelancer-specific deductions: Freelancers can claim expenses such as business equipment, home office costs, and professional development courses.

Home Office and Its Impact on Tax Returns in Germany

With the rise of remote work, many employees and freelancers in Germany now work from home. This shift has made home office expenses an important topic for tax deductions. Understanding how to claim home office expenses correctly can help reduce taxable income and maximize tax refunds. This guide explains the eligibility criteria, deductible expenses, and how to include home office costs in your tax return.

Eligibility for Home Office Deductions

Not everyone who works from home can claim a deduction. To be eligible, the following conditions must be met:

The home office must be a dedicated workspace that is used exclusively for work. A shared space like a kitchen or bedroom corner generally does not qualify.
The employee or freelancer must not have access to a suitable workspace at their employer’s office (applicable mainly to employees who work remotely full-time or frequently).
Freelancers and self-employed individuals often have more flexibility in claiming home office deductions.

Deductible Home Office Expenses

Several types of expenses can be deducted when claiming home office costs:

Flat-Rate Home Office Deduction

A simplified deduction of €6 per day, up to a maximum of €600 per year (i.e., 100 workdays) can be claimed.
No need to provide detailed proof of individual costs, making it the easiest option for employees working remotely for a limited number of days.

Actual Cost Deduction

For those who meet strict eligibility criteria (i.e., the home office is the primary place of work), the following expenses can be claimed:

Proportional Rent & Utilities: If a separate room is used exclusively for work, a percentage of rent, electricity, water, and heating costs can be deducted based on the proportion of the workspace’s size compared to the total living space.
Furniture & Equipment: Desks, chairs, shelves, and lamps purchased for work purposes can be deducted.
Internet & Phone Bills: A reasonable portion of monthly costs can be claimed for work-related usage.
Work Supplies: Paper, pens, printers, and other necessary office materials are eligible expenses.

How to Claim Home Office Expenses in the Tax Return

Determine Deduction Type: Choose between the flat-rate deduction or the actual cost deduction.
Gather Documentation: Keep receipts and invoices for work-related purchases.
Calculate the Deductible Amount:
- If using the flat rate, calculate €6 per work-from-home day (max €600 per year).
- If using actual costs, determine the workspace size as a percentage of the total living area and apply it to rent and utilities.
Enter in Tax Forms:
- Employees: Enter deductions under Anlage N (Werbungskosten – Work-Related Expenses).
- Freelancers & Self-Employed: Declare expenses under Anlage S (Self-Employment Income) or Anlage EÜR (Income-Expense Statement).
Submit the Tax Return: Use ELSTER, tax software, or a tax consultant to ensure accuracy.

Special Considerations

Homeowners: Mortgage interest and property maintenance costs related to the workspace can also be deducted.
Tax Office Audits: If claiming a high amount, the Finanzamt (tax office) may request proof such as rental agreements, utility bills, and workspace photos.
Employer Reimbursements: If an employer reimburses work-from-home expenses, these amounts cannot be claimed again in the tax return.

Claiming home office expenses can lead to significant tax savings if done correctly. Whether using the flat-rate method for simplicity or calculating actual costs for higher deductions, understanding the process ensures compliance with German tax laws. Proper documentation and accurate reporting will help maximize deductions and prevent issues with the tax authorities.

Final Recommendations

Filing your tax return in Germany is essential for compliance and potential refunds. Whether using ELSTER, tax software, or a tax consultant, organizing your records and filing on time ensures a stress-free process. Understanding your tax class, keeping detailed records, and being aware of deductions can help you maximize your return.
