Turning Investment Losses Into a Tax Break
📉 A stock you own is down $4,000 and you're annoyed about it. Wall Street is not annoyed; Wall Street is filing paperwork. There's a move that turns a loss on paper into a real discount on your tax bill — and most people leave it sitting in their portfolio, unused.
💡 Key idea
A realized loss can cancel out taxable gains (and a bit of income). Just don't buy the same (or substantially identical) asset within 30 days before or after the sale — the wash-sale rule.
🧠 Why it matters
Tax-loss harvesting means selling an investment that is down to lock in the loss, then using that loss to offset gains you owe taxes on — or up to $3,000 of regular income per year, with extra losses carried forward. You can reinvest in something similar (but not identical, to avoid the wash-sale rule) so you stay in the market. It turns a paper loss into a smaller tax bill.
🌍 In the real world
🧮 An investor had a $4,000 gain in one fund and a $4,000 paper loss in another. Instead of paying tax on the gain, she sold the loser, used the loss to offset the gain entirely, and bought a similar (not identical) fund to stay invested. Her taxable gain for the year: zero. Same market exposure, a real tax saving — purely from timing the sale smartly.
📌 Takeaways
- Sell a loser to offset taxable gains, plus up to $3,000 of income a year
- Carry leftover losses forward to future years
- Beware the wash-sale rule: no buying the same or substantially identical asset within 30 days before or after the sale
