Specific Identification

Specific identification is an accounting method that allows a trader to choose exactly which specific lots of an asset are being sold, rather than relying on a default assumption like FIFO. This gives the investor significant control over their tax liability, as they can choose to sell lots with higher cost bases to minimize gains or lots with lower cost bases to realize losses.

This method requires meticulous record-keeping to prove which specific assets were sold at the time of the transaction. While it offers the greatest tax optimization potential, it also carries a higher administrative burden and requires precise documentation to satisfy tax authorities.

It is highly valued by active traders who want to manage their tax outcomes with surgical precision.
