Tax Optimizer

Take control of your taxes by changing tax lot-matching methods on the fly to optimize your capital gains and losses.

• Change the default matching method for your account, the current trading day or the prior trading day.
• Run real-time "what-if" scenarios to see how different lot-matching methods affect your gains and losses.
• Choose from among several tax lot-matching methods, including LIFO, FIFO, Maximize Long-Term Gain, Maximize Long-Term Loss, Maximize Short-Term Gain, Maximize Short-Term Loss and Highest Cost.
• Manually match specific lots to trades using the Specific Lot matching method.
• Make changes and save them until 8:30 PM ET on any given trading day.
• View year-to-date profit and loss data by symbol.
