| This is not true for assets that change in value and illiquid/non-marketable assets. Example: Rich person buys asset for $10m. 3 years later gets it appraised for $75m, knowing full well that no one would actually buy it for that. Rich person then donates the '$75m' asset to charity. Rich person made more money via charity rather than trying to sell the asset for $75m. This is a very common strategy. |
If the article genuinely depreciated in value, then the burden falls on the taxpayer to prove this, and in illiquid markets this is very difficult to establish.
