Does Tax-Loss Harvesting Work in Retirement? When and How to Use It

How Does Tax-Loss Harvesting Work in Retirement?

Sell an investment at a loss. Use the loss to offset capital gains dollar-for-dollar. If losses exceed gains, deduct up to $3,000 against ordinary income. Remaining losses carry forward to future years.

In retirement, the primary uses: 1. Offset gains from portfolio rebalancing 2. Offset gains from selling appreciated positions to fund spending 3. Offset Roth conversion income (losses reduce AGI, which can increase ACA subsidies and reduce SS taxation) 4. Offset required taxable income in years with large RMDs

Wash-sale rule: You cannot repurchase the same or substantially identical security within 30 days before or after the sale. You CAN buy a different fund in the same asset class (e.g., sell one S&P 500 fund, buy another).

When Is It Most Valuable?

Tax-loss harvesting has the highest value: - In the year of a large Roth conversion (losses offset conversion income) - When ACA subsidies are at stake (lower AGI = larger premium tax credit) - During market downturns (more opportunities for losses) - When you have large accumulated gains from long-held positions

Less valuable when: you're already in the 0% capital gains bracket, you have minimal taxable investments, or all your investments are in tax-advantaged accounts.
