Taxes are calculated on a federal level, cantonal level, and city level. At federal level you are taxed on rental value if you have a mortgage. At canton and city level you are taxed both on rental and property value. Local taxes on property are often significantly more than federal taxes. In both cases you can deduct mortgage interest, PPE fees or other maintainance fees, and your standards tax deducations, ie health insurance and expenditures, some insurances, such as life, etc. Totals property taxes are usually, in my experience, about .03 % of value of property per year, but this depends on deductions.

Hope this helps.

Tracy posted her questions five years ago, so let’s hope she’s found some answers in the interim.

@Ritchie Oops!  I hadn't noticed that.  
It looks as if it was bumped back to life yesterday.

These things happen – and maybe your input will help someone else.

Best, R.
