German residents with US RSUs: complete tax + filing guide for 2026

You're at SAP Walldorf, Google Munich, Meta Berlin, BMW Munich's tech division, or a US bank's Frankfurt operations. Your US RSUs vest. The German tax framework is uniquely structured: Lohnsteuer at marginal rate on vest, but flat Abgeltungsteuer (≈26.4%) on capital gains and dividends. This guide covers both.

The 30-second answer: German residents pay marginal Lohnsteuer (income tax up to 45% + 5.5% Solidaritätszuschlag + church tax if applicable) on RSU vest, plus Sozialversicherung where applicable. Cost basis = FMV at vest in EUR. Capital gains and dividends from private US stock holdings taxed at flat Abgeltungsteuer of ≈26.375% (25% + 5.5% surcharge). US dividend WHT: 15% with W-8BEN under Article 10 of US-Germany Tax Treaty. Report on Anlage KAP (Einkommensteuererklärung); German tax year = calendar year; return due 31 July.

German tax year and timeline

• Tax year: calendar year
• Tax return due: 31 July of following year (self-filing)
• With tax adviser (Steuerberater): typically until 31 May of subsequent year
• Filing system: Elster (electronic) or paper

The vest event — German mechanics

When your US RSUs vest while you're German resident:

1. Vest value = FMV × shares at vest date in USD
2. Convert to EUR at ECB reference rate on vest date
3. Vest income classified as Sachbezug (employment-in-kind) under § 19 EStG
4. German employer reports via Lohnsteuerbescheinigung to tax authorities
5. Lohnsteuer withheld at marginal rate plus Solidaritätszuschlag + church tax + Sozialversicherung
6. Cost basis for future Abgeltungsteuer = FMV at vest in EUR

German income tax (Einkommensteuer) rates 2025

Plus:

• Solidaritätszuschlag: 5.5% of income tax (largely abolished for low/middle earners since 2021 but applies above ≈€69K income)
• Church tax: 8% (Bavaria, Baden-Württemberg) or 9% (other states) of income tax, if you're registered with a church
• Sozialversicherung: ≈20% combined (pension, health, unemployment, care) on earnings up to ceilings

Top effective rate for high earner without church: 45% + 2.475% (Soli) = 47.475% With church: ≈51.5%

Abgeltungsteuer — Germany's flat tax on capital income

Since 2009 tax reform, capital income earned in private (non-business) holdings is subject to flat Abgeltungsteuer:

• 25% Abgeltungsteuer (Kapitalertragsteuer)
• + 5.5% Solidaritätszuschlag of the 25% = +1.375%
• + Church tax (8-9% of 25%) if applicable = +2-2.25%

Without church: 26.375% With church: ≈28.4-28.6%

Critical advantage: for high-income earners, Abgeltungsteuer is materially lower than marginal income tax (45%+). The flat rate creates a structural incentive to hold capital assets in private capacity.

Applies to:

• Capital gains on share sales (regardless of holding period since 2009)
• Dividend income
• Interest income
• Bond income

Exemption — Sparer-Pauschbetrag:

• €1,000 annual allowance (single)
• €2,000 annual allowance (married filing jointly)
• First €1,000/€2,000 of capital income is tax-free
• Triggered by Freistellungsauftrag (exemption order) at German broker

For foreign-broker-held assets, you must explicitly declare and apply allowance via Anlage KAP.

US dividend withholding for German residents

Under Article 10 of US-Germany Tax Treaty:

• Without W-8BEN: 30% default
• With W-8BEN: 15% reduced rate

German side:

• Gross dividend (EUR converted) reported on Anlage KAP
• German tax at Abgeltungsteuer 26.375%
• US WHT 15% creditable

Example: $100 USD dividend, EUR 0.92 per USD:

• Gross EUR: €92
• US WHT (15%): €13.80
• Net received: €78.20
• Reported on Anlage KAP: €92
• German Abgeltungsteuer (26.375%): €24.27
• Foreign tax credit: €13.80
• Net German tax due: €10.47
• Effective rate: (€13.80 + €10.47) / €92 = 26.375% (the Abgeltungsteuer rate)

The US WHT credits dollar-for-dollar (within limits) against German tax.

Capital gains on US stock sales — Abgeltungsteuer mechanics

For shares acquired AFTER January 1, 2009 (post-Abgeltungsteuer reform):

• Capital gain = sale proceeds − cost basis (both in EUR)
• Taxed at flat Abgeltungsteuer 26.375%
• No holding period distinction (no LTCG advantage like UK/Australia/US)

For shares acquired BEFORE January 1, 2009 (grandfathered):

• Generally tax-free if held >1 year (the old rule)
• Rare for current FAANG employees

For US RSU vests (which occur post-2009): always subject to Abgeltungsteuer.

Compared to other jurisdictions:

Germany is mid-pack on capital gains tax for top bracket.

Anlage KAP — the German tax return supplement

For German residents with foreign capital income, Anlage KAP must be filed since German broker source-tax discharge doesn't apply to foreign brokers.

Key sections:

• Zeile 7: Capital gains from share sales
• Zeile 15-19: Dividend income breakdown
• Zeile 41: Foreign capital income (Auslandskapitalerträge)
• Zeile 51: Foreign tax to be credited (anrechenbare ausländische Steuer)
• Sparer-Pauschbetrag: apply exemption (Zeile 16)

EUR conversion methodology: ECB reference rate on transaction date. Document the rate used per transaction.

Best brokers for German residents

For RSU consolidation from US employer broker:

• IBKR Germany or Comdirect typical destinations
• Sophisticated FX handling matters for cost basis tracking

For ongoing US stock investment:

• Trade Republic or Scalable Capital for retail
• IBKR for active investors

Riester / Rürup / bAV — German retirement wrappers

For long-term US stock exposure within German tax framework:

Riester (since 2002)

• Government-subsidized retirement savings
• Contribution + state subsidy
• Tax deduction during contribution
• Pension taxed in retirement
• US stock investment via ETF-based Riester products possible but limited

Rürup (since 2005)

• For self-employed and high-earners
• Higher contribution limits
• Larger tax deduction
• Pension taxation in retirement
• More flexibility for US stock exposure

Betriebliche Altersvorsorge (bAV)

• Employer-sponsored
• Tax-deferred contribution
• Pension taxed in retirement

For most US RSU holders, these German wrappers are SECONDARY to direct stock investment due to flexibility constraints. The Abgeltungsteuer rate (26.4%) on private stock holding is already competitive enough that wrapper benefits are marginal.

Cross-border vesting

For German residents whose RSU vesting period included US workdays:

• Workday attribution under US-Germany Treaty Article 15
• US-source portion taxable in US; German-source in Germany
• US tax creditable via FTC mechanism

For complex cross-border situations, consult cross-border specialist.

Strategic playbook for German RSU holders

1. Sell at vest for diversification — convert to EUR, reinvest broadly
2. Use Sparer-Pauschbetrag fully — €1,000/€2,000 annual allowance is small but compounds
3. Maintain W-8BEN — 15% US WHT instead of 30%
4. Track foreign tax credit carefully on Anlage KAP
5. Document EUR conversion at ECB reference rate per transaction
6. Consider ETF-Steuerreform 2018 mechanics — for ETF holdings, "Vorabpauschale" (advance lump-sum tax) applies even without realization. Get specific advice.
7. Maximize bAV contributions if employer offers — tax-efficient retirement saving
8. Avoid Riester/Rürup unless specifically advised — restrictive structures

Common German RSU mistakes

1. Not filing Anlage KAP — foreign capital income MUST be declared (source-tax discharge doesn't cover foreign broker)
2. Wrong EUR conversion methodology — use ECB reference rate, document per transaction
3. Missing Vorabpauschale on US ETFs — annual advance lump-sum tax for some ETF holdings
4. Not claiming foreign tax credit for US WHT
5. Confusing Lohnsteuer (employment) with Abgeltungsteuer (capital) — different rates
6. Late filing — penalties + interest accumulate

The closing read

For German residents with US RSUs, three principles:

1. Vest income at full Lohnsteuer marginal rate (up to 47%+)
2. Capital gains and dividends at flat Abgeltungsteuer 26.375% — meaningfully lower than marginal income tax for high earners
3. File Anlage KAP carefully — foreign capital income compliance is the main German-specific complexity
