Q: What are the tax implications when moving from Germany to the Netherlands?

Understand how your income, investments, and equity compensation are taxed when relocating from Germany to the Netherlands, including residency cut-off dates, double tax treaty rules, and cross-border pitfalls.

Relocating from Germany to the Netherlands changes more than your address : it can trigger significant tax consequences.
From final German tax filings to Dutch 30% ruling applications, you’ll need to coordinate both systems to avoid double taxation and optimize your after-tax position.

Quick Answer

Residency cut-off: Germany taxes you as a resident until you give up your German residence (Wohnsitz) and register your departure (Abmeldung).
Split-year taxation applies in both countries : Germany taxes income until your departure date, the Netherlands taxes income from your arrival date.
Treaty rules prevent double taxation, but you must file in both countries.
Special items like RSUs, bonuses, and capital gains may be allocated between countries based on where work was performed or where assets are located.

1. Determining your last day of German tax residency

Your tax residency in Germany generally ends when you:

Deregister (Abmeldung) your address at the Bürgeramt, and
No longer have a home available to you in Germany.

If you keep a property or rental home in Germany, you may still be considered resident unless it’s rented out long-term.

2. Split-year taxation & double tax treaty

Germany and the Netherlands have a double taxation agreement (DTA) that determines which country taxes specific income.

Key points:

Employment income is usually taxed where the work is physically performed.
Equity compensation (RSUs, stock options) is allocated based on workdays between grant and vest.
Capital gains on securities are generally taxed in your country of residence at the time of sale.
Real estate income remains taxable in the country where the property is located.

3. Example : RSUs after moving

If your RSUs vest after you’ve moved:

Germany may still tax the portion of the benefit linked to German workdays between grant and vest.
The Netherlands may tax the full benefit if you’re resident there at vest.
The DTA provides for credit or exemption to avoid double taxation : but only if you claim it properly.

4. Special considerations

Bonuses : Allocated based on where the work was performed, not payment date.

Pensions : German state pensions remain taxable in Germany; Dutch pensions taxed in the Netherlands. Private pensions may have different treatment.

Investments : Be aware of Dutch Box 3 wealth tax on worldwide net assets each January 1st, including German bank accounts and portfolios.

30% ruling : High-skilled migrants moving to the Netherlands may apply for this expat tax advantage. Since 1 January 2024, the ruling uses a phased structure over a maximum of 60 months (5 years):

First 20 months: 30% of salary is tax-free.
Next 20 months: 20% of salary is tax-free.
Final 20 months: 10% of salary is tax-free.

Employees who already held the 30% ruling before 1 January 2024 are grandfathered under the old flat 30% rule for the remainder of their ruling period.

5. Avoiding common mistakes

Not filing a final German tax return : required even if you think all income is taxed in the Netherlands.
Assuming the treaty automatically removes double taxation : you must actively claim credits/exemptions.
Forgetting Dutch wealth tax on assets held outside the Netherlands.
Missing the 30% ruling application window (within 4 months of starting work). Note that since January 2024, the ruling is phased (30/20/10% over 5 years) rather than a flat 30%, so the benefit decreases over time.

6. Timeline for a smooth move

3–6 months before move : Review RSU vesting dates, bonus schedules, and investment sales timing.
Before leaving : Deregister your address, close or convert local accounts, settle taxes.
Arrival in Netherlands : Register with the municipality, apply for 30% ruling (if eligible), open Dutch accounts.
Following spring : File both German and Dutch tax returns for the split year.

Example : salary, RSUs, and investments

Move date: 1 July 2025
Salary: €100k annually : Germany taxes Jan–June (€50k), Netherlands taxes July–Dec (€50k).
RSUs vesting in Oct 2025 : allocated between countries based on grant-to-vest workdays.
Investment portfolio : no German tax after departure; Dutch wealth tax applies as of 1 Jan 2026.

German terms to know

Abmeldung : deregistration from German municipality.
Doppelbesteuerungsabkommen (DBA) : double taxation agreement.
Wegzugsbesteuerung : exit tax (applies mainly to large shareholdings in companies, not listed shares).

Checklist
