Tax Lots

A tax lot is a record of each BUY order in thinkorswim®, including data used to calculate tax outcomes. Tax lots help traders with tax strategies by identifying differences between shares in the same position.

Each filled BUY order creates a tax lot with the following details:

Open Date The date on which the trade that first opened this position was made. 
Symbol The underlying asset’s trading symbol.
Exp The expiration date, if applicable. 
Strike The strike price to be paid if the option is exercised, for applicable options. 
Type The type of the  security the position is in. 
Qty The amount of a security held in the position.
Cost/Share The average trade cost per share adjusted for fees, commissions, wash sales, and certain corporate actions.
Mark The current market price of the symbol.
Total Cost The total trade cost adjusted for fees, commissions, wash sales, and certain corporate actions.
Net Liq The total value of the position if it were immediately closed.
P/L Open The profit or loss since the position was opened.
Holding Time Defines  the position is long-term or short-term holding for tax purposes. 
Wash Sale Defines whether  the position is a wash sale where a security is sold at a loss but then the same instrument or a substantially similar one is bought again within 30 days (Y for yes, N for no).
