Tax Loss Harvesting with Options: Strategies to Lower Your Tax Bill

Summary

Tax loss harvesting means selling losing investments to realize capital losses that offset gains. Options add powerful tools to this strategy: you can harvest losses while maintaining market exposure through different positions, use puts to lock in unrealized stock losses without selling, and strategically time option expirations for year-end tax planning. The key challenge is avoiding wash sale rules that would disallow the loss.

Key Takeaways

Capital losses offset capital gains dollar-for-dollar, and up to $3,000 of excess losses offset ordinary income annually. Options create harvesting opportunities beyond simply selling losing stock. You can sell a losing option position and immediately enter a meaningfully different options position on the same underlying—different strike, different expiration, different strategy type—while potentially avoiding wash sale issues. Always consult a tax professional on wash sale interpretations.

December is when most traders think about tax loss harvesting, but the best approach is year-round. Every time you close a losing options trade, you're generating a harvestable loss. The question is whether you can redeploy that capital without triggering a wash sale.

Strategy 1: Harvest Losing Long Options

If you hold a long call or put that's lost significant value, sell it to realize the loss. Then wait 31 days before buying a similar option, or immediately switch to a different approach.

Example: You hold 10 SPY $560 calls bought for $8,000, now worth $2,000.

  • Sell the calls: realize $6,000 loss
  • Wait 31 days and re-enter, or
  • Immediately buy SPX calls instead (different underlying, no wash sale)
  • Or sell SPY puts as an alternative bullish position (different security type, though wash sale risk exists)
  • Strategy 2: Use Protective Puts to Lock In Stock Losses

    You own stock with a large unrealized loss but don't want to sell. Buy an at-the-money put to lock in the loss, then sell the stock after the put gives you downside protection.

    Example: You own 200 shares of XYZ at $80, now at $60 ($4,000 unrealized loss).

  • Buy 2 ATM $60 puts for $3.00 ($600)
  • Wait until the appropriate time to sell the stock
  • The put protects you from further decline while you plan the optimal tax timing
  • Warning: Buying puts on stock you own and selling the stock at a loss within 30 days can trigger the wash sale rule. The put purchase might be deemed "substantially identical" to the stock. Time your transactions carefully.

    Strategy 3: Roll Losing Positions to Different Strikes

    If you're selling covered calls or puts and the position is losing money, you can roll to a different strike/expiration to realize the loss on the original trade while opening a new position.

    Example: You sold 5 TSLA $250 puts for $4,000 credit. TSLA dropped and the puts are now worth $7,000 (you're down $3,000 on paper).

  • Buy back the $250 puts for $7,000 (realize $3,000 loss)
  • Sell new $220 puts for $5,000 credit (different strike)
  • The $3,000 loss is harvested. The new $220 puts are arguably a different security (different strike), though aggressive wash sale interpretations might disagree. Using a meaningfully different strike and expiration strengthens your position.

    Strategy 4: Year-End Expiration Timing

    Options that expire worthless in December create losses in the current tax year. Options expiring in January push the loss to next year.

    Planning approach:

  • Identify losing long options before year-end
  • If they'll expire worthless soon, let them expire in December (or sell for any remaining value in December)
  • If you have large gains to offset, accelerate loss realization before December 31
  • Strategy 5: Pair Options Gains and Losses

    Active options traders often have a mix of winning and losing positions. Strategically close losing positions in the same year as your largest gains to minimize net taxable gain.

    Year-end review process:

  • Calculate total realized gains YTD
  • Identify unrealized losses in open positions
  • Close enough losing positions to offset gains (or reduce them below the next tax bracket threshold)
  • Use OptionsPilot's trade tracking to identify your largest unrealized losses across all positions
  • Strategy 6: Switch Underlying to Avoid Wash Sales

    Sell a losing AAPL call and buy a MSFT call. Different underlying, no wash sale. You've harvested the AAPL loss and maintained tech exposure.

    For index exposure: sell losing SPY options, buy IVV or VOO options. The IRS hasn't explicitly ruled on similar ETFs, but many tax professionals consider different ETFs as different securities. This is less clear-cut, so document your reasoning.

    How Much Can You Save

    If you harvest $20,000 in options losses against $20,000 in gains:

  • At 32% short-term rate: $6,400 in tax savings
  • At 37% rate: $7,400
  • If you have no gains, $3,000 offsets ordinary income ($1,110 savings at 37%) with the rest carrying forward.

    Common Mistakes

  • Ignoring the 30-day window. Buying back a substantially identical option within 30 days erases the loss.
  • Not tracking across accounts. Purchases in your IRA can trigger wash sales on taxable account losses.
  • Harvesting small losses while missing large ones. Focus on the biggest unrealized losses first.
  • Forgetting state taxes. Loss harvesting benefits vary by state. States with no income tax offer no additional state-level savings.
