What is tax-loss harvesting, and how can it reduce my tax liability?

Published: Friday, March 27, 2026 · Last Updated: Friday, March 27, 2026

For investors with taxable accounts, tax-loss harvesting can be a valuable strategy to help manage tax liability while staying committed to a long-term investment plan.

Put simply, tax-loss harvesting involves selling investments that have declined in value from their purchase price or cost basis to realize a loss. These losses may then be used to help offset realized gains elsewhere in a portfolio, or, in some cases, reduce taxable income within certain limits.

While the concept is straightforward, effective implementation requires coordination with your overall investment and tax strategy.

A Tool for Managing Investment Taxes

Losses harvested from taxable investments can be used to offset capital gains, which may occur when selling other appreciated assets. If losses exceed gains, a limited portion may be used to reduce ordinary income, with any unused amount carried forward to future years.

It’s also important to consider holding periods, as short-term and long-term capital gains are taxed differently. Tax-loss harvesting strategies typically take this into account to align with broader goals and timelines.

However, not every market dip results in action. Tax-loss harvesting is one of many tools that may be considered depending on your overall plan, tax picture, and investment philosophy. It’s also subject to IRS rules – like the wash-sale rule – that may disallow a loss if a substantially identical security is repurchased too soon.

When Does Tax-Loss Harvesting Make Sense?

For many high-net-worth investors, tax-loss harvesting is most effective when:

  • Managing a large capital gain from another investment or liquidity event
  • Rebalancing a portfolio in a tax-conscious way
  • Navigating year-end tax planning opportunities

It’s not about reacting to short-term market movements, but rather making informed decisions within a larger, proactive strategy.
