Options & Taxes
You can be a great trader and still lose a significant chunk of your profits to taxes if you do not understand the rules. Options taxes are more complex than stock taxes, with traps that can surprise even experienced traders. This is not tax advice — consult a CPA — but every options trader needs to understand these concepts.
Basic Tax Treatment of Options
Short-term capital gains: Profits from options held less than one year are taxed as short-term capital gains at your ordinary income tax rate (up to 37% federal).
Since most options trades last days to weeks, nearly all options profits are short-term. If you make $50,000 trading options and you are in the 32% bracket, you owe roughly $16,000 in federal taxes. Add state taxes and you might keep only $30,000 to $35,000.
Long-term capital gains: Options held more than one year (LEAPS, for example) qualify for the lower long-term rate (0%, 15%, or 20% depending on income). But how often do you hold an option for over a year? Rarely.
Section 1256 Contracts: The Tax Advantage
Index options (SPX, NDX, RUT, VIX) and futures receive special treatment under Section 1256:
- 60% of gains taxed as long-term (max 20%)
- 40% of gains taxed as short-term (max 37%)
- Blended rate: approximately 26.8% at the highest bracket
This applies regardless of holding period. Even a 0DTE SPX trade that lasted 2 hours gets the 60/40 treatment.
The math on $50,000 profit:
- SPY options (regular): $50,000 x 37% = $18,500 in tax
- SPX options (1256): $30,000 x 20% + $20,000 x 37% = $6,000 + $7,400 = $13,400 in tax
- Savings: $5,100 per year
If you trade S&P 500 strategies, switching from SPY to SPX saves you thousands annually. On $100,000 in profits, the savings approaches $10,000.
Mark-to-Market Reporting
Section 1256 contracts use mark-to-market accounting. At year-end, all open positions are treated as if they were closed at fair market value on December 31. You pay tax on unrealized gains.
Example: You sell an SPX iron condor on December 20 for $3.00 credit. On December 31, it is worth $1.50 (you are up $1.50 in profit). You must report $150 per contract as a 2024 gain even though you have not closed the trade.
When you close the trade in January 2025, the gain or loss is calculated from the December 31 mark, not from your original entry. This prevents double-taxation but requires careful record-keeping.
Wash Sale Rules
The wash sale rule prevents you from claiming a tax loss if you buy a "substantially identical" security within 30 days before or after the sale.
How it applies to options:
You sell a TSLA $250 call for a $500 loss on March 1. On March 15, you buy a TSLA $250 call with a different expiration. The IRS considers this substantially identical. Your $500 loss is disallowed and added to the cost basis of the new option.
The gray areas:
- Is a $250 call and a $260 call substantially identical? The IRS has not provided clear guidance. Most tax advisors say different strikes are NOT substantially identical, but this is not settled law.
- Is a SPY call and SPY shares substantially identical? Probably not, but some advisors are cautious.
- Is selling a put and buying a call on the same stock substantially identical? Likely not — they are different types of securities.
Practical approach: If you close an option at a loss, wait 31 days before opening a position on the same underlying with the same strike. Or switch to a different expiration and strike. Document your rationale.
Wash Sales Across Accounts
Wash sales apply across ALL your accounts — IRA, taxable, spouse's account. If you sell AAPL calls at a loss in your taxable account and buy AAPL calls in your IRA within 30 days, the wash sale rule applies. The loss is disallowed in the taxable account AND it does not even add to the IRA's cost basis. The loss disappears entirely.
This is a trap that costs traders real money. Be careful.
Options Assigned or Exercised
If your short put is assigned: The put premium reduces your cost basis in the stock. You sold a $180 put for $3. Assigned at $180. Cost basis: $177.
If your short call is assigned: The call premium increases your selling price. You sold a $200 call for $4 against stock you own. Called away at $200. Selling price: $204.
If a long option expires worthless: The total premium paid is a capital loss in the year of expiration.
If a long option is exercised: The premium becomes part of the cost basis (for calls) or reduces the sale price (for puts).
Tax-Efficient Strategies
Use SPX instead of SPY. The single easiest tax optimization. Same underlying exposure, 10% lower tax rate.
Harvest losses before year-end. If you have losing positions in December, consider closing them to realize the loss for tax purposes. Then re-enter in January if your thesis is still intact (mind the wash sale rule).
Offset short-term gains with long-term losses. Long-term losses first offset long-term gains, then short-term gains. But short-term losses first offset short-term gains, then long-term gains. Plan your loss harvesting accordingly.
Consider an LLC or S-Corp. Active traders may benefit from electing "trader tax status" with the IRS (Section 475(f)). This allows you to deduct trading expenses, avoid wash sale rules, and report gains/losses on Schedule C. The requirements are strict — you must trade frequently, substantially, and continuously. Consult a tax professional.
Use tax-advantaged accounts for frequent trading. If you trade iron condors weekly, doing so in a Roth IRA means all gains are tax-free. The downside: no margin (limited to defined-risk strategies) and you cannot deduct losses.
Record-Keeping
Your broker provides a 1099-B at year-end, but it may not correctly handle options adjustments, assignments, and wash sales. Keep your own records:
- Every trade: entry date, exit date, strategy, cost basis, proceeds
- Assignments and exercises: document the flow from option to stock or cash
- Wash sales: track 30-day windows on every loss
- Section 1256 mark-to-market: note open positions at December 31
Software like TradeLog or GainsKeeper can automate much of this. The $150 to $300 annual cost is worth it if you make more than 50 trades per year.
The tax code does not care about your trading strategy. But your after-tax return is the only number that matters. Next: backtesting your strategies to ensure they work before you risk real money.
