How to File a Tax Return in Germany (Steuererklärung)

Filing a tax return in Germany (Steuererklärung) might seem daunting, but understanding the process, deadlines, and key deductions can save you significant money and help you stay compliant with the Finanzamt. Whether you're an employee, self-employed, or a business owner, this guide walks you through everything you need to know for the 2025 tax year.

Who Must File a Tax Return in Germany?

Not everyone in Germany is required to file a tax return. You're obligated to submit one if you fall into any of these categories:

• You're married and your spouse has tax class V or VI, or you've elected the tax class IV factor
• You've received untaxed secondary income or replacement benefits (such as short-time working allowance or parental allowance) exceeding €410
• You're claiming deductions for business expenses, special expenses, or extraordinary burdens
• You're self-employed or operate a business
• You have rental or leasing income
• You're a pensioner whose income exceeds the basic tax allowance

If you're not required to file but have paid too much tax through your employer, submitting a voluntary return is an excellent way to claim a refund.

Key Deadlines for 2026

The deadline for submitting your 2025 tax return depends on how you file:

• Self-filed returns: 31 July 2026 — If you complete your return yourself or use tax software like Accountable or ELSTER
• With a tax advisor: 1 March 2027 — If you engage a Steuerberater (tax consultant), you'll have until March 2027, but you must hire them in time

Missing the deadline carries consequences. Those who fail to submit by 31 July 2026 face a late filing surcharge of at least €25 per commenced month. Planning ahead and gathering your documents early is essential.

Important Tax Changes for 2026

Higher Basic Tax Allowance

Good news for your wallet: the basic tax allowance (Grundfreibetrag) increases by €252 to €12,348 in 2026. This means more of your income remains tax-free. Additionally, the entire income tax schedule has been adjusted to prevent "bracket creep" — where pay increases designed to offset inflation push you into higher tax brackets.

Degressive Depreciation for Business Assets

If you're self-employed or run a business, you can now claim degressive depreciation (geometrisch-degressive Abschreibung) for moveable business assets. This allows you to deduct acquisition costs much faster than traditional linear depreciation.

Here's a practical example: if you purchase a company vehicle for €30,000 in July 2026, you can immediately deduct 30% (€9,000) in the first year, rather than €6,000 under the old 20% linear method over five years. For businesses facing economic uncertainty, this is a meaningful advantage.

Essential Deductions and Tax Savings

Home Office and Work Equipment

You can claim the home office flat rate (Homeoffice-Pauschale) or deduct actual expenses for a dedicated workspace. Additionally, work-related equipment, tools, and software are fully deductible business expenses.

Commuting and Travel Costs

Your daily commute to work qualifies as a deductible business expense. Keep records of your travel costs, whether you drive, use public transport, or cycle.

Professional Development and Training

Courses, certifications, and training related to your profession are deductible. This includes language courses, industry certifications, and conference attendance.

Union Membership and Professional Fees

Contributions to unions (Gewerkschaftsbeiträge) and professional associations count as special expenses and reduce your taxable income.

How to File Your Tax Return

Gather Your Documents

Before you begin, collect all relevant paperwork:

• Your annual income statement (Lohnsteuerbescheinigung) from your employer
• Receipts and invoices for deductible expenses
• Bank statements for business income and expenses (if self-employed)
• Insurance premium statements (health, pension, unemployment)
• Rental income or investment income documentation
• Charitable donation receipts
• Child allowance confirmations (Kindergeld)

Choose Your Filing Method

You have three main options:

• ELSTER (online): Germany's official free electronic tax filing system. You can file directly through the ELSTER portal or use approved tax software that integrates with ELSTER
• Tax software: Programs like Accountable, SteuerSparErklärung, or others guide you through the process step-by-step
• Tax advisor: A Steuerberater or tax consultant prepares and submits your return for you

Complete the Main Form and Required Attachments

The main tax return form (Hauptvordruck) is always accompanied by the "Anlage Vorsorgeaufwand" (Appendix for Provisions), which includes health insurance and pension contributions. You'll add additional schedules only if they apply to your situation — for example, Schedule S for self-employment income or Schedule V for rental income.

Digital Submission with ELSTER

Once you've completed your return using ELSTER or compatible software, you can digitally sign and submit it directly to your local Finanzamt. This eliminates the need to print, sign, and mail a paper copy.

Pre-Filled Tax Returns (VaSt)

The Finanzamt can pre-fill certain sections of your return with data they already hold — such as income reported by your employer, child allowances, and insurance contributions. You can opt into this service and review the pre-filled information before submission, making the filing process significantly faster.

Special Considerations for Self-Employed and Business Owners

If you're self-employed or operate a business, your filing requirements are more comprehensive. You'll need to submit:

• A detailed income and expense statement (Einnahmen-Überschuss-Rechnung or EÜR)
• Documentation of all business income and deductible expenses
• VAT returns (if applicable)
• Trade tax filings (Gewerbesteuer) if you operate as a sole proprietor or partnership

A tax advisor can be invaluable here, ensuring you maximise deductions and remain compliant with all regulations.

Next Steps

Start preparing now, even though the deadline isn't until 31 July 2026. Begin collecting receipts and organising your documents throughout the year. If you're unsure whether you need to file, contact your local Finanzamt or consult a tax advisor for personalised guidance.

Remember: every deduction you claim legally reduces your tax bill. Taking time to file accurately and completely ensures you pay only what you owe — no more, no less.
