New regulation of property tax from 2020

Hi Elina, I was there for eleven years. It was super nice, you just need to be clear about one thing: afterward, you will never be able or want to work in DE again. a) Salary there and b) Tax rates there. Those are really worlds apart...

No, I have planned it differently. In short, I want to "take advantage" of both the double household management in DE and the pension in Switzerland. The reason is that my pension entitlement in DE currently amounts to 28 euros, as I only got a job after turning 40 due to my disability. That won't increase much, even if I work hard for another 25 years. Taxation in DE will unfortunately remain, because we don’t want/can’t sell our house here for the time being and my husband continues to work here, although he is applying for jobs in CH, but so far nothing is in sight.

The plan is that I keep my job in DE (I certainly won’t voluntarily quit my first job, which is now permanent, who knows if I will ever find another one). Since the company is located in Konstanz but I live near Wiesbaden, I could simply rent an apartment on the Swiss side and then deduct this as double household management on my taxes. With the distances and rental costs in CH, we would effectively pay almost no taxes anymore.
I would then work 3 days a week in my apartment in CH and 2 days I would have to commute to Konstanz for work, as otherwise I wouldn’t have a "primary workplace," which I need to claim double household management.

According to my information, I would then pay all social security contributions and health insurance in CH and be out of the German social security system because I mainly work in my private apartment, which would then be my place of work. After only one year, I would be entitled to the CH minimum pension, which currently, I believe, is around 1200 euros. I can only dream of that in DE.
Health insurance in CH is private and initially more expensive than in DE, but I have calculated that if I work full-time from next year, it balances out. And the costs of the second apartment would be easily covered by the tax savings from the income-related expenses. So I am now waiting for my position to be set to 100%. Currently, it is 70% (since January, before that 50%). At the moment it is not worth it.

This is only possible because my job is completely home office and the employer is located on Lake Constance.
So if I haven't miscalculated, it's a great opportunity to save taxes and significantly improve the pension.
Later, it might happen that we sell the house here and my husband joins me in Switzerland. There seem to be jobs in the chemical industry; you just have to be lucky.
