Tax-Lot Selling Sequence Optimization for After-Tax Wealth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The American financial services industry has not introduced significant improvements in managing taxable equity portfolios over two decades, relying on traditional tax efficiency approaches that focus on minimizing taxes in a year.
Innovation Solution
The Efficient Tax Portfolio Optimizer (ETPO) is a computerized system and method that uses complex mathematical calculations to determine the best sequence and combination of tax-lots to sell, maximizing after-tax wealth over a specified time horizon by identifying and recommending the sale of tax-lots that generate the greatest excess after-tax returns.

Engineering Contradiction Analysis
1Loss of energy
If traditional tax efficiency approach is used to minimize taxes in a year, then tax minimization is improved, but after-tax wealth maximization over time horizon is worsened
Solution Approach 1:
The system dynamically adjusts the selling sequence and combination of tax-lots based on changing market conditions, time horizon, and tax implications. Rather than static one-year tax minimization, the optimization adapts to maximize after-tax wealth over the investor's specific time horizon by continuously evaluating which tax-lots to sell first, second, or last based on projected after-tax returns.
Solution Approach 2:
The system changes the parameter of optimization from single-year tax minimization to multi-period after-tax wealth maximization. It incorporates time horizon as a key parameter, along with projected after-tax returns, to determine the optimal selling sequence. This parameter change transforms the objective function from minimizing current taxes to maximizing future after-tax wealth.
2Manufacturing precision
If individual tax-lot after-tax value is optimized, then after-tax proceeds for individual lots is improved, but portfolio-level optimization is worsened
Solution Approach 1:
The system merges individual tax-lot optimization with portfolio-level strategy. Instead of optimizing lots independently, it integrates them into a unified portfolio optimization framework that determines the optimal sequence and combination of lots to sell. This combining approach ensures that individual lot decisions contribute to overall portfolio after-tax wealth maximization rather than optimizing in isolation.
Solution Approach 2:
The system segments the portfolio into distinct tax-lots with different holding periods, cost bases, and tax implications. By segmenting at the tax-lot level while optimizing at the portfolio level, it can precisely control which specific lots are sold first, second, or last, enabling granular control over tax consequences while maintaining portfolio-level strategic objectives.
3Productivity
If selling sequence is optimized to maximize after-tax returns, then after-tax wealth is improved, but tax-loss harvesting opportunities are worsened
Solution Approach 1:
The system performs preliminary analysis of all tax-lots to identify which ones should be sold first, second, or last based on projected after-tax returns. This preliminary sequencing decision-making process ensures that tax-loss harvesting opportunities are captured in the optimal selling sequence, rather than being addressed as an afterthought. The preliminary action determines the entire selling sequence to maximize after-tax wealth while incorporating tax-loss harvesting where beneficial.

A computerized system, computer-implemented method, and/or computer-readable medium for analyzing of a portfolio of tax-lots to facilitate maximization or optimization of after-tax wealth over a specified time horizon, by determining a sequence for selling of individual tax-lots, across an entire portfolio of taxable equity security tax-lotsin a manner that achieves the maximization or optimization of after-tax wealth over a specified time horizon, by performing processing to identify the (i) selling first those tax-lots, in descending sequence, that by doing so would generate the greatest excess after-tax returns, or alpha, and (ii) then, if additional sales are desired, selling in a manner that gives up the least opportunity cost of doing so by selling first, in ascending order, those tax-lots with the least after-tax return potential remaining.
