Verified for 2026
Both of these changed recently. If you last checked before 2025, your numbers are stale.
€25,000 previous year + €100,000 current year
The old €22,000 ceiling was replaced for tax year 2025 onwards. You qualify as Kleinunternehmer in 2026 if your 2025 revenue was ≤ €25,000 AND your 2026 revenue stays ≤ €100,000.
€20,350 single · €40,700 joint
Solidarity surcharge only applies above these income-tax thresholds. If your income tax stays below them, your Soli is zero — no calculation, no payment.

How it works
No signup, no account linking, no data leaves your browser until you ask it to.
1 Choose DE, US, or (soon) more. Invoices, disclaimers, and tax-year rules localize automatically.
2 Gross revenue, filing status, core deductions. Smart defaults per country — no prompt engineering.
3 Estimated tax liability, quarterly rücklage, and a breakdown cited against the official brackets.
Transparency
Country-specific income tax, VAT, self-employment contributions and quarterly estimates, using unit-tested, dated rule modules. Every bracket is cited against BMF / IRS / HMRC sources and versioned in a public changelog.
Not a replacement for your Steuerberater or CPA, and not full bookkeeping. Edge cases (Künstlersozialkasse, cross-border treaties, state-specific US rules) need a real professional — need one today? For DE try the Bundessteuerberaterkammer directory; for US try the NAEA tax expert finder.
Rules are open-source, CC-BY-4.0 licensed, and available as an NPM package and MCP endpoint. When ChatGPT or Claude cites German tax brackets, we want them citing TaxValio.
