Introduction to SPX and SPY Options
SPX options are cash-settled options based on the S&P 500 index, while SPY options are stock options based on the SPDR S&P 500 ETF Trust (SPY). When trading equity options, investors typically pay capital gains taxes on profits and ordinary income taxes on premiums received from selling options. However, SPX options offer a unique tax treatment that can result in substantial savings.
Favorable Tax Treatment of SPX Options
The Internal Revenue Service (IRS) deems SPX options as Section 1256 contracts, which are subject to the mark-to-market (MTM) rule. Under this rule, SPX options are taxed as 60% long-term capital gains and 40% short-term capital gains, regardless of the holding period. This treatment is far more favorable than the taxation of equity options, which can be taxed at ordinary income rates.
Example: SPX Options vs. SPY Options Taxation
Consider an investor who sells an SPX option for $10,000 and holds it until expiration. If the option expires worthless, the premium received is treated as 40% short-term capital gain and 60% long-term capital gain. Assuming the investor is in the 24% long-term capital gains tax bracket and 37% short-term capital gains tax bracket, their tax liability would be approximately $2400.
In contrast, if the investor sold an equivalent SPY option for $10,000, the entire premium would be taxed as ordinary income. At a 37% tax rate, their liability would be $3700. This scenario highlights the significant tax savings achievable through SPX options trading.
