Reduction of the capital gains tax by making a subsequent payment to the buyer.
For various reasons, we had to sell our rented (and therefore not self-occupied) single-family house in August 2019. This property was acquired in March 2010, so capital gains tax is due and we will have to pay it in 2020 along with our 2019 income tax return.
However, the buyers are now demanding a compensation payment for issues that arose and were not communicated, after the purchase price has been paid and the property has been handed over. There will likely be an out-of-court settlement with the buyers.
The question now arises whether such a - retrospective - compensation payment can be deducted from the original capital gains and, more importantly, whether this is still possible even if the corresponding "defect rectification payment" is made in 2020. The negotiations are likely to drag on for a while. Any payment to the buyers would still be related to the sale proceeds.
