Soli on Your 2025 Steuererklärung May Be Unconstitutional — How Indian Expats Earning Over €75K Can File an Einspruch to Protect a Potential Refund

The Soli You're Still Paying Might Not Be Legal — Here's What to Do About It

If you're an Indian IT professional in Germany earning over €75,000, you probably noticed a line on your payslip called Solidaritätszuschlag — or simply "Soli." It's 5.5% of your income tax, and it adds up to a significant chunk of money every year.

Here's the thing: Germany's Federal Fiscal Court (Bundesfinanzhof, BFH) has referred the Soli to the Constitutional Court, questioning whether it's even legal anymore. The case is pending under BVerfG 2 BvL 6/24.

If the court rules in taxpayers' favour, you could be entitled to a refund of every euro of Soli you've paid — but only if you keep your tax assessment open. That's where an Einspruch (formal objection) comes in.

Let's walk through exactly what this means for your 2025 Steuererklärung, which is due by 31 July 2026.

A Quick History: Why Does the Soli Still Exist?

The Solidaritätszuschlag was introduced in 1995 to fund the costs of German reunification. For three decades, every taxpayer paid it. In 2021, the government exempted roughly 90% of taxpayers by introducing a generous exemption threshold.

But here's the catch: higher earners still pay the full Soli. The government kept it because, well, it generates billions in revenue. The BFH's argument is straightforward:

• The Soli was always meant to be temporary.
• Reunification-related expenses are no longer a special financial burden.
• Continuing to levy the surcharge only on higher earners may violate the principle of equal treatment under the German Basic Law (Grundgesetz).

The Constitutional Court has accepted the referral but hasn't ruled yet. A decision could come in 2026 or 2027.

Who Still Pays the Soli in 2025?

Not everyone. Here are the thresholds for the 2025 tax year:

If your income tax liability stays below the threshold, you pay zero Soli — congrats, this article doesn't apply to you. But if you're a senior developer, team lead, architect, or engineering manager on a Blue Card, you're very likely above that line.

How Much Soli Are You Actually Paying?

Let's do the math for Rajesh:

€1,177 per year. That's a significant amount — roughly the cost of a return flight to India. Over three or four years of working in Germany, that's €3,500–€4,700 in Soli alone.

Now imagine getting all of that back if the Constitutional Court says the Soli is unconstitutional.

The Critical Step: Filing an Einspruch

Here's the part most people miss. Even if the Constitutional Court rules the Soli unconstitutional, the Finanzamt will only refund your Soli if your tax assessment (Steuerbescheid) is still "open."

Once your Steuerbescheid becomes bestandskräftig (legally final) — which happens automatically one month after you receive it — it's locked. No refund, no matter what the court decides later.

The solution? File an Einspruch within one month of receiving your 2025 Steuerbescheid. This keeps the Soli portion of your assessment legally open while the Constitutional Court deliberates.

What Happens After You File an Einspruch?

1. The Finanzamt acknowledges your Einspruch — usually within a few weeks.
2. They will likely issue a Ruhensbeschluss (dormancy order), suspending your objection until the Constitutional Court decides. This is standard and expected — don't panic.
3. You still pay the Soli as assessed. The Einspruch does not suspend your payment obligation. You pay now; you get refunded later if the court rules in your favour.
4. If the court rules the Soli unconstitutional, the Finanzamt automatically adjusts all open assessments and issues refunds.

How to Write Your Einspruch — A Template

The Einspruch doesn't need to be complicated. Here's a simplified structure:

To: Your local Finanzamt (address on your Steuerbescheid)

Subject: Einspruch gegen den Einkommensteuerbescheid 2025 — Solidaritätszuschlag

Body (key points to include):

• Your Steuernummer and the date of the Steuerbescheid
• State that you are objecting specifically to the Solidaritätszuschlag
• Reference the pending Constitutional Court case: BVerfG 2 BvL 6/24 (referral by BFH, case II R 27/21)
• Request that the assessment remain open (offen) regarding the Soli until the court issues its ruling
• Request a Ruhen des Verfahrens (dormancy of proceedings) per § 363 Abs. 2 AO

You can send the Einspruch via:

• ELSTER (upload as a message to your Finanzamt)
• Registered mail (Einschreiben — recommended for proof of delivery)
• Fax (yes, German authorities still accept fax)

What If You've Already Received Past Steuerbescheide Without Filing an Einspruch?

If your 2023 or 2024 assessments are already final (bestandskräftig), those years are generally closed. You cannot retroactively file an Einspruch once the one-month window has passed.

That's exactly why acting now on your 2025 return matters. Don't let this one slip by too.

A Real-World Scenario: Protecting Your Refund

The cost of filing an Einspruch? Zero. There's no fee, no risk, and no downside. If the court upholds the Soli, your assessment simply becomes final as originally issued. You lose nothing.

Should You Consult a Steuerberater?

For most Indian expats earning over €75K, the Einspruch for Soli is fairly straightforward. However, you should consider consulting a licensed Steuerberater if:

• You have complex income (freelance income, rental income in India, capital gains)
• You're unsure whether you're above or below the Soli threshold after all deductions
• You want to combine the Einspruch with other objections (e.g., disputed deductions)
• You're leaving Germany soon and want to ensure your case stays open even after departure
