Close relatives include your children, grandchildren, parents and grandparents. Your siblings are not considered closely related family members.
Generally, you may sell your home at a price corresponding to 85-115% of the public assessment of property without being charged gift tax.
However, in certain cases, the difference between the market value, which is the price for which similar homes are being sold, and a sales price within 85-115% of the public assessment of property may be considered a gift. This applies if special circumstances indicate that a sales price which differs maximum 15% from the most recent public assessment of property corresponds to the market value.
If you sell your home to a price lower than 85% of the public assessment of property or a lower market value, the difference will be considered a gift. However, it will not be considered a gift, if you sell your home to less than 85% of the public assessment of property if this corresponds to the market value.
If the gift exceeds the limit for gifts between closely related family members, gift tax will be charged.
As the seller, you will be taxed on the profit according to general rules.
