On my B permit it does not say I cannot do this, so maybe some B permit holders are allowed to use this method.
What I want to know is if I can choose myself where my main residence is, as I want it to be the weekday one, not the weekend one

.
If you register in the second kanton and move in with someone, does their tax increase, like household waste tax and so on? Also, I have heard that if you become a wochen/wochendaufenthalter, you can claim many more deductions on your tax form. Anyone done this or know the details? (Travel deductions and the like??)
