It's a subtlety, but gain on the last asset between the time it is acquired and the end of the year (or the time it's sold) is not taxable or recognized, and I think not realized.Famspear wrote: ↑Sun Jul 14, 2019 11:04 pm Because Robert purchased the original asset for $50,000, Robert has a basis of $50,000. When Robert transfers the asset to John by gift, the receipt by John is non-taxable to John for Federal income tax purposes (Code section 102), and John has a carryover basis in that asset of $50,000.
John then barters that asset away in one or more transactions and, by the end of the year, ends up with an asset with a value of $85,000. The difference of $35,000 ($85,000 minus $50,000) is the total gain (or gains) John has realized. In this example, the $35,000 realized gain is also the recognized gain, since we haven't posited any additional facts that would make the gain be non-taxable.
In this case, $35,000 excess of the value of the last asset held at the end of the year over John's basis in the asset he acquired from Robert also happens to be equal to the total gain (or gains) John realized. (It is also equal to John's recognized gain.)
Suppose some of this gain is through actual gain in value, not due to John cheating his barter participants. At the last trade of 2018 he trades an asset worth $80,000 for the last asset. If the last asset is worth $85,000 at the end of the year, because of appreciation, John is only taxed on $30,000. (The details of short-term capital gains vs. ordinary income are too complicated to go into, and require more details than either of us wants to go into.) The last $5,000 is not taxed until he sells or exchanges the asset.
