Hello all,
I recently (2026) completed the purchase of an empty plot in order to build on it, along with my partner. I am seeking the experience and wisdom of the forum for next year’s taxes.
First thing is that we both own 50% of it, despite me putting in more money. Now, the notary was pretty clear, if we do nothing this will be considered a gift and apparently taxed at 50% since we’re not married.
This would result in a very significant tax payment for me, so totally a no go.
According to him, it’s good enough to simply note each year the debt/loan in the tax declaration for both of us. However, I would like something a bit more formal than that: a signed document by the both of us recognising the debt (but not notarized, just something written).
So question 1: is it fine to simply write “A owns X to B”, with no interest payments or a repayment plan? I guess no interests is fine given the current rates, but I’m afraid I write it wrong and it’s taken as proof it’s a gift. LLM suggests to put a “repayment on sale of the property” condition to avoid any issues, which sounds reasonable. Any experience here?
Also, we’re planning on getting married somewhat soon, I don’t know if it changes things. We would most likely use the default properties status.
Second thing, I took out some of my 3rd pillar for this. I know I’ll pay a tax on it for the withdrawal, but is there anything to mention directly in the tax declaration? Same thing for 2nd pillar (even if I didn’t use it).
Final question. Since I’m the owner and builder, and it’s quite likely the construction will not be completed before the end of the year, it appears I will be taxed (for wealth) based on the value of the property at the end of the year. Apparently, it’s not just the value of the land, but also the value of whatever is already there on top. Anyone knows who gives that value? The tax office will not know the state of the construction, so I’m not sure how it works.
Thanks!
