Frequently asked questions
- What is tax-loss harvesting?
- Tax-loss harvesting is the strategy of selling investments at a loss to offset capital gains and reduce your tax bill. You can use up to $3,000 in net losses to offset ordinary income each year, with excess losses carried forward.
- How does the tool work?
- TrackMyShares scans your portfolio for holdings with unrealized losses, estimates your potential tax savings based on your marginal tax rate, and flags any wash sale risks before you execute trades.
- Does it detect wash sales?
- Yes. Before you harvest a loss, the tool checks whether you have purchased the same security within the 61-day wash sale window and warns you if selling would trigger a wash sale violation.
- Can I see lot-level detail?
- Yes. The tool breaks down each holding by individual purchase lot, showing you the cost basis, current value, and unrealized gain or loss for each lot.
- How is the tax savings estimated?
- The estimated tax savings is calculated by multiplying the harvestable loss by your marginal tax rate. This gives you an approximation of how much you could reduce your tax bill.
