TaxLotTuner

TaxLotTuner is a web app (with a companion mobile view) that helps individual investors rebalance while minimizing avoidable taxes and trading friction. Instead of blindly selling to hit target weights, it imports holdings from major brokerages, analyzes tax lots, and proposes a rebalance plan that prioritizes: using new contributions, directing dividends, harvesting losses where appropriate, and only then selling the most tax-efficient lots. It shows a plain-English breakdown of estimated capital gains, wash-sale risk flags, and how far you’ll drift if you choose a “no-sell” option. The app generates an execution checklist per brokerage (and where supported, places trades via read/write APIs). It’s not a magic alpha machine—its value is reducing costly mistakes and making rebalancing less intimidating. Pricing is subscription with a low-cost tier for simple portfolios and a higher tier for multi-account households.
