Every year, a remarkable amount of money sits unclaimed with the German tax office, refunds that employees are owed but never file to collect. The German tax return has a reputation for being fearsome, and so people skip it, not realising that for most ordinary employees it ends not in a bill but a cheque. The system withholds tax from your pay as a rough estimate, and once you file and claim the deductions you are entitled to, commuting, work costs, that home office you have been using, the over-withheld money comes back. Average refunds run from a few hundred to well over a thousand euros. Leaving it unclaimed is leaving your own money behind.
This guide covers the German tax return: why most people get a refund, the deductions you are probably missing, how to file simply, and the deadlines. Turn the dreaded Steuererklärung into a payday.
Most people get a refund
The reassuring core fact: most employees in Germany get a refund when they file. Here is why.
Your wage tax is withheld monthly as an estimate (visible on your payslip), calculated as if your situation were simple and static. But the deductions you can claim, work costs, commuting, insurance, and more, reduce your actual taxable income below what was assumed.
So filing reconciles the estimate against reality, and since deductions usually lower your tax, the over-withheld amount comes back as a refund. The average refund is several hundred to over a thousand euros, real money, routinely.
This is the same withhold-then-reconcile logic that benefits students and everyone with claimable costs: the monthly withholding overshoots, and filing claws back the difference. So the German tax return, far from being a feared bill, is for most ordinary employees a refund waiting to be claimed. The only way to lose is not to file.
Must you file, or should you?
Two separate questions:
Must you file (mandatory)? It depends. Many simple employees are not obliged to file, your wage tax is withheld automatically and that can be the end of it. But some situations make filing mandatory:
- Multiple incomes or income beyond your main job
- Certain benefits received
- Certain tax-class combinations (e.g. married 3/5)
- Self-employment or freelance income
So check whether you must file (the mandatory cases have the 31 July deadline, below).
Should you file (voluntary)? Even if not obliged, you likely should, because most get a refund. A voluntary return to claim your refund is almost always worth the effort for an employee with deductible costs.
So the practical takeaway: determine if you are a mandatory filer (then you must, by the deadline), but if you are not, file voluntarily anyway to claim the refund you are probably owed. The downside of voluntary filing is minimal (you can choose not to submit if it somehow shows you owe), the upside is your refund. Your tax class affects both your obligation and your refund.
The deductions you are missing
The size of your refund depends on the deductions you claim, and many people under-claim, leaving money behind. Common deductions:
- Commuting costs (the Pendlerpauschale), a per-kilometre allowance for your commute, often a big one
- Work-related expenses: equipment, tools, training, professional literature, a home office (the home-office allowance)
- Certain insurance contributions
- Job-application costs (applications, travel to interviews)
- Work-related travel
- Special expenses (Sonderausgaben) and extraordinary burdens (außergewöhnliche Belastungen)
Many employees miss these and under-claim, leaving refund money on the table. The commuting allowance alone is significant for anyone with a real commute; the home-office allowance adds up for hybrid/remote workers; work equipment and training are commonly overlooked.
So the way to maximise your refund is to keep receipts and claim everything legitimate. Go through the categories above, gather what applies, and claim it all. The difference between a minimal return and a thoroughly-claimed one can be hundreds of euros. The deductions are the lever, the more legitimate costs you claim, the more of your over-withheld tax comes back.
How to file (it is easier than you think)
Filing is more approachable than its reputation:
- ELSTER: the free official tax portal, where you submit directly
- Tax software and apps: several work in English and guide you step by step
For a simple employee return, a guided app makes it straightforward, it walks you through income and deductions in plain language, often in English, and is well worth the small cost for the ease and the prompts (which help you not miss deductions). You report income and deductions, and the Finanzamt calculates your refund or any amount owed.
So you do not need to be a tax expert or fluent in German to file. A guided English app turns the Steuererklärung into a form-filling exercise with helpful prompts. For more complex situations (self-employment, property, complicated incomes), a tax adviser (Steuerberater) may be worth it, but a typical employee can file themselves with an app or ELSTER.
The deadlines
Timing differs by filer type:
- Mandatory return: deadline generally 31 July of the following year (later if you use a tax adviser)
- Voluntary return (to claim a refund): you have much longer, generally up to four years back
So if you are a mandatory filer, mind the July deadline (missing it can mean penalties). If you are filing voluntarily to claim a refund, you have flexibility, up to four years back, which means you can file for previous years you missed and claim those refunds now. This is the same backfiling window that lets people recover refunds from years they never filed.
So a practical bonus: if you have been in Germany a few years and never filed, you can likely still claim refunds for past years (up to four back), potentially several refunds at once. Do not assume the past is lost; voluntary returns reach back.
The bottom line: the German tax return is, for most employees, a refund, not a bill. File (mandatory or voluntary), claim all your deductions (commuting, work costs, home office, insurance), use a guided app or ELSTER, mind the July deadline if mandatory, and reach back up to four years for missed refunds. The effort is modest; the money is real and yours.
What to do this week
- Check whether you are a mandatory filer (multiple incomes, certain tax classes, self-employment); if not, plan to file voluntarily anyway, since most employees get a refund.
- Gather receipts and claim every legitimate deduction, commuting (Pendlerpauschale), work costs, home office, insurance, since under-claiming is the main reason refunds are smaller than they should be.
- File via ELSTER or a guided English app, mind the 31 July deadline if mandatory, and consider backfiling up to four years for refunds from past years you never claimed.
