If you want to continue to use the Dutch health care system, you can take out voluntary health insurance with a German health insurance company. This will allow you to use the Dutch health care system (as if you were insured in the Netherlands).
Becoming an entrepreneur in Germany can be a complicated matter, so it is advisable to consult an accountant or tax adviser who specialises in insurance matters beforehand. They can also provide you with further information on the differences in tax deductions for a company car, for example.
You may be able to take out voluntary health insurance with a health insurance company or take out private insurance. If you take out voluntary insurance with a health insurance fund, you can also take out daily benefits insurance. In general, voluntary health insurance with a health insurance fund is more advantageous because you can then continue to use the healthcare system and the AWBZ in the Netherlands. This is not possible with private insurance.
You may be able to take out voluntary statutory pension insurance with the German pension insurance fund for both old-age pension, survivors’ pension and pension due to reduced earning capacity. Of course, you can also take out private pension insurance.
If, in addition to your entrepreneurial activity, you are also employed, the employment relationship determines where you are socially insured. The decision in this context is independent of whether you are also self-employed in Germany or the Netherlands.
Becoming self-employed or setting up a business in Germany
Other institutions are also involved in assisting entrepreneurs who want to work across the border. In the Netherlands you can get a lot of information from the Kamer van Koophandel, in Germany from the IHK (Chamber of Industry and Commerce) as well as the Kreishandwerkerschaft [district association of craftsmen], among others.
If you want to become self-employed or start a business in North Rhine-Westphalia, you can find a lot of information at the Einheitlichen Ansprechpartner [Single Point of Contact].
