Tax-Loss Harvesting With Option Overlays

Tax-loss harvesting is one of the few moves that can lower a tax bill without changing your long-term plan: sell a position at a loss, use the loss to offset realized gains, and redeploy the proceeds. The complication is that options touch two separate sets of rules — the wash-sale rule and the straddle rules — and both can quietly undo a harvest that looked clean.

How does tax-loss harvesting work?

You sell a security trading below your cost basis, realizing a capital loss. That loss first offsets capital gains of the same character, then the other character, and up to $3,000 of ordinary income per year, with the remainder carried forward. Near year-end, harvesting is often paired against gains already realized during the year — including gains from selling down a concentrated position — so the net taxable amount is reduced.

What is the wash-sale rule, and how do options trip it?

The wash-sale rule disallows a loss if you acquire a substantially identical security within 30 days before or after the sale that generated the loss — a 61-day window in total. The disallowed loss is added to the basis of the replacement position rather than lost outright. Options matter here because buying a call on the same security, or even writing a deep in-the-money put, can count as acquiring a substantially identical interest and trigger the rule. Re-establishing exposure through options is not a way around it.

• Selling at a loss and buying the same stock back within 30 days disallows the loss.
• Buying a call on the same security inside the window can be treated as a substantially identical acquisition.
• The disallowed loss is not erased — it shifts to the basis (and holding period) of the replacement position.

How do the straddle rules interact with a harvest?

The straddle rules under IRC §1092 are separate from the wash-sale rule and apply when you hold offsetting positions that substantially reduce the risk of loss — for example, long stock with a protective put or a collar. If one leg has a loss and you still hold the offsetting leg, the straddle rules can defer recognition of that loss until the offsetting position is closed. So a harvest taken while a hedging option is still in place may not be currently deductible, even if it clears the wash-sale test. The qualified-covered-call exception narrows where the straddle rules bite for properly structured calls, but it does not remove the analysis.

When does harvesting near year-end make sense?

Harvesting tends to fit when you have realized gains to offset, a position trading below basis, and a way to maintain market exposure without repurchasing a substantially identical security inside the window. Pairing a harvest with a paced sell-down of a concentrated position can offset some of the gain that the sell-down realizes. The order of operations — close hedges, realize the loss, observe the window, then redeploy — is what keeps the wash-sale and straddle rules from colliding.

The wash-sale rule, the straddle rules, and the qualified-covered-call exception interact in fact-specific ways, and the outcome turns on the exact positions and timing as well as current law, which can change. Confirm the sequencing with a qualified tax professional before harvesting around an option position.
