In this episode of the Motley Fool Hidden Gems Investing Project’s Saturday Personal Finance Edition, host Robert Brokamp explains how investors can turn investment losses into tax benefits, detailing ten essential tips for managing losses and gains in non-retirement accounts.
### Tax-Loss Selling Fundamentals
Even with the S&P 500 near all-time highs, many individual stocks and sectors are underwater. Robert Brook explains that investors can use losses in taxable accounts (excluding IRAs, 401ks, or HSAs) to reduce taxable income:
* **Broader than stocks:** Tax-loss selling applies to bonds, mutual funds, ETFs, and options contracts. For example, the Vanguard Total Bond Market ETF remains down over 20% from its 2020 peak. Crypto can also be used, though it has different rules requiring separate research. Personal property like a house is excluded.
* **Short vs. long-term matching:** On Schedule D, investors must categorize sales as short-term (held for a year or less) or long-term (held for longer than a year). Short-term losses offset short-term gains, and long-term losses offset long-term gains, with remaining losses offsetting each other. Excess losses can reduce ordinary taxable income up to $3,000 per year ($1,500 for married filing separately) and lower Adjusted Gross Income (AGI), which can positively impact tax credits, Roth IRA contributions, healthcare costs, and financial aid. Carry-forward losses can be used in subsequent years.
### Avoiding the Wash Sale Trap
* **The 30-day rule:** Do not buy back a sold investment within 30 days of the sale date, or the transaction is considered a "wash sale," disallowing the loss on Schedule D. The 61-day window covers the sale day, 30 days before, and 30 days after. Reinvesting dividends during this period also triggers a wash sale.
* **Substantial equivalents:** Buying a substantially identical investment, purchasing through another account (like an IRA), buying call options, or swapping an index ETF for another tracking the same exact index will violate the rule. However, investors can maintain similar market exposure by swapping an S&P 500 ETF for an ETF tracking a different index, or buying a sector-specific ETF.
### Cost Basis and Specific Shares
* **Multiple cost bases:** Reinvested dividends or multiple purchases mean a holding can have a mix of gains and losses.
* **Specifying shares:** Investors should avoid simply clicking "sell" and instead designate a specific cost basis method. Default methods include First-In, First-Out (FIFO) for stocks and ETFs, and average cost for mutual funds. Brokers must report cost basis and holding periods for assets bought after 2011, but older assets require manual record-checking.
### Managing Gains and Strategic Caveats
* **Harvesting gains:** Single individuals with taxable income under $49,450 or married couples under $98,900 in 2026 face a 0% tax rate on long-term capital gains, allowing them to sell and immediately buy back investments for a tax-free reset to a higher cost basis.
* **Potential costs & risks:** Investors must weigh trading fees, bid-ask spreads, and the risk of missing market rebounds—especially in December, which historically experiences positive returns over 70% of the time. Furthermore, harvesting a loss and buying back at a lower price creates a lower cost basis, which could lead to larger capital gains and higher taxes if the investor expects to be in a higher future tax bracket.
* **Death and donations:** Capital loss carry-forwards die with the investor. Conversely, heirs receive a stepped-up cost basis on non-retirement assets valued as of the date of death, erasing capital gains taxes. Donating long-term appreciated investments to qualified nonprofits allows investors to avoid capital gains taxes entirely, deduct the contribution if itemizing, and buy back shares immediately with the cash they would have otherwise donated.
Robert Brook advises listeners to perform their own research and consult a tax professional before making financial decisions.
