How it works
Our system prioritizes your tax savings by selecting to sell securities in the order listed below:
- Short-term capital loss from largest to smallest.
- Long-term capital loss from largest to smallest.
- Short-term zero gain or loss.
- Long-term zero gain or loss.
- Long-term capital gain from smallest to largest.
- Short-term capital gain from the smallest to largest.
The MinTax cost basis method is generally designed to lower an individual's tax burden for the current transaction by identifying securities to sell based on the most favorable tax rate using the ordering rules described above. Each category is exhausted before moving to the next. If the cost of the original share is unknown, we'll treat the cost basis as zero.
In many cases, the MinTax cost basis method may reduce the tax impact, but it does not guarantee the lowest total tax liability. This method prioritizes selling assets based on their potential tax rates by category—such as favoring long-term over short-term gains—rather than selecting shares with the lowest gains. For example, if a taxable account holds a position with a large long-term capital gain (e.g., $100,000) and a small short-term capital gain (e.g., $10), the MinTax method may choose to sell the long-term gain first due to its lower tax rate, even though it results in a higher total gain. Therefore, the shares with the most favorable tax rate might not be the ones with the lowest gain. For investors specifically aiming to minimize total gains when selling, the HIFO (Highest In, First Out) method may be more appropriate, as it targets the lowest possible total gains. The effectiveness of any cost basis method will vary depending on individual circumstances.
