The Voluntary Tax Return: Money Many People Leave Behind

As an employee in Germany, you often don’t have to file a tax return at all — your employer withholds wage tax (Lohnsteuer) every month. That’s exactly why so many people hand a refund to the tax office each year without realizing it.

Monthly wage tax is only a rough estimate. The moment you had work-related expenses above the standard allowance, worked only part of the year, or got married mid-year, you probably overpaid. A voluntary tax return (Antragsveranlagung) is how you claim that money back — and as an expat, this is one of the most useful things to know about the German system.

In short: If you aren’t required to file, you can still file voluntarily — and up to four years back (§ 46 EStG). Your 2025 return is possible until December 31, 2029, and your 2022 return until December 31, 2026. There’s no late-filing penalty, and according to Germany’s Federal Statistical Office the average refund is around €1,100.

Mandatory or Voluntary? (§ 46 EStG)

Whether you must file or simply may file is governed by § 46 of the Income Tax Act (EStG). There are two paths:

Mandatory return (Pflichtveranlagung) — you’re required to file. This applies, for example, if:

  • your side income exceeds €410 (e.g., rental income or freelance work on the side),
  • you received wage replacement benefits over €410 (parental allowance, short-time work allowance, unemployment benefit — these raise your tax rate through the “progression clause”, Progressionsvorbehalt),
  • you and your spouse used the tax class combination III/V (or IV with a factor),
  • an allowance (Freibetrag) was registered on your wage tax deduction, or
  • you had more than one employer at the same time (tax class VI).

Mandatory returns have a deadline: July 31 of the following year.

Voluntary return (Antragsveranlagung) — if none of the mandatory reasons apply, you file voluntarily (§ 46 Abs. 2 No. 8 EStG). You “apply” for assessment simply by submitting your return. And here a much more generous deadline applies.

The 4-Year Window: How Far Back You Can File

For a voluntary return you have four years. This follows the four-year assessment period (Festsetzungsfrist, § 169 AO), which starts at the end of each tax year.

Tax yearVoluntary return possible until
2022December 31, 2026
2023December 31, 2027
2024December 31, 2028
2025December 31, 2029

In plain terms: even if you never filed for 2022, 2023, 2024, or 2025, you can still do it now — up to four refunds at once. But watch the clock: the 2022 window closes at the end of 2026. Anything not filed by then is gone for good.

Tip: Start with the oldest open year. That’s the one whose deadline expires first — the money you’re at risk of losing soonest.

Who Benefits From a Voluntary Return?

Not everyone gets money back automatically, but a lot of people do. These groups benefit most often:

The Finanzamt automatically deducts the employee lump-sum allowance of €1,230 (Arbeitnehmer-Pauschbetrag) for everyone. If your actual work-related expenses (Werbungskosten) were higher, every euro above that lowers your taxable income. Typical items: a long commute (Pendlerpauschale), work equipment, training, a second household for work, or a job-related move. For an overview of what employees can claim, see our page for employees.

Anyone who worked only part of the year

This is the classic situation for new graduates, career starters, and anyone who took a longer break — including expats who arrived partway through the year. Wage tax is calculated each month as if you earned the same all year. If you only worked a few months, too much was withheld — and the annual assessment gives it back.

Couples and special situations

  • Marriage during the year — the income-splitting tariff (Splittingtarif) often applies retroactively for the whole year.
  • Special expenses (Sonderausgaben) — donations, pension contributions, church tax.
  • Extraordinary burdens — high medical costs above the reasonable-burden threshold.
  • Tradespeople and household help — you deduct 20% of the labor costs for craftsmen’s services (§ 35a EStG) and household-related services directly from your tax.

No Late-Filing Penalty — and Almost No Risk

The big advantage of filing voluntarily: because there is no filing obligation, there is no deadline to miss — and therefore no late-filing penalty. A surcharge under § 152 AO only applies when you were required to file and were late.

And what if, against expectations, the return shows you owe money? You’re not trapped: you can file an objection (Einspruch) against the assessment and withdraw your request. No tax is then assessed, and you’re back where you started. That’s why a voluntary return carries virtually no risk.

Example: A Career Starter Gets Over €1,500 Back

Meet Lena, single, tax class I. She finished university and starts her first job in July at €4,000 gross per month.

  • From July to December she earns €24,000.
  • Her employer withholds wage tax each month as if she earned €48,000 for the whole year — at a high rate.
  • In reality her annual income is only €24,000, which is taxed far more lightly.

The annual assessment corrects this: Lena gets back a large share of the overpaid wage tax — depending on her expenses, easily €1,500 to €2,000. Add work-related expenses above the lump sum (say, moving costs to her first job) and the refund grows further.

A simpler second example: with €2,730 in work-related expenses you’re €1,500 above the lump-sum allowance. At a marginal tax rate of around 30%, that alone is roughly €450 back.

How to File Your Voluntary Return

The easiest way is through ELSTER, Germany’s official online tax portal. You register once (activation arrives by post after a few days), then complete:

  1. Main form (Mantelbogen) — your personal details.
  2. Anlage N — employment income and work-related expenses (commute, work equipment, training).
  3. Additional forms as needed — e.g., pension expenses, special expenses, household-related costs.

You do not submit receipts up front — you keep them on hand should the Finanzamt ask. So hold on to them.

How Restio Helps

The most common reason people leave a refund behind: they aren’t sure it’s worth the effort, and they lose track of the four-year window. That’s exactly where Restio comes in:

  • Deadline watch — Restio keeps track of how far back you can still file each year and reminds you before a December 31 deadline expires.
  • Scan your receipts — photograph invoices, travel costs, and receipts throughout the year, so nothing is missing when you fill in your work-related expenses.
  • Understand your Finanzamt letter — when the assessment arrives, photograph it and Restio explains in plain language whether your entries were accepted and how your refund was calculated.

Get Restio and reclaim the years that are still open.

Conclusion

The voluntary tax return is one of the best opportunities in the German tax system: optional, retroactive, and carrying virtually no risk. The essentials:

  • Four years to file — 2022 through 2025 are still open (§ 46, § 169 AO)
  • 2022 closes at the end of 2026 — don’t wait any longer
  • No late-filing penalty — and if you’d owe money, you can withdraw
  • Especially worthwhile — with high work-related expenses, or if you worked only part of the year
  • File through ELSTER — the main form plus Anlage N

Check your open years and you’ll likely stop leaving four-figure sums with the tax office. For more tax basics, see the Restio home page.

Frequently Asked Questions

What's the difference between a mandatory and a voluntary tax return in Germany?

A mandatory return (Pflichtveranlagung) is required — for example if you have side income over €410 or tax class V. A voluntary return (Antragsveranlagung) is one you file even though you don't have to, usually because you expect a refund (§ 46 EStG).

How many years back can I file a voluntary tax return in Germany?

Four years. You can file your 2025 return until December 31, 2029, and your 2022 return until December 31, 2026. This follows the four-year assessment period (Festsetzungsfrist, § 169 AO).

Is there a late-filing penalty on a voluntary tax return?

No. With a voluntary return there is no filing obligation and therefore no deadline you could miss. A late-filing surcharge (Verspätungszuschlag, § 152 AO) only applies to mandatory returns.

What if my voluntary return actually shows I owe money?

You can file an objection (Einspruch) against the assessment and withdraw your request. No tax is then assessed. That's why a voluntary return carries virtually no risk.

How do I file a voluntary tax return in Germany?

Through ELSTER, Germany's official online tax portal. You complete the main form (Mantelbogen) and Anlage N (the employee income form) and submit digitally — you keep receipts on hand only if the Finanzamt asks for them.
