SPX vs SPY Options Taxes: How the Section 1256 60/40 Rule Works
Same Market, Different Tax Bill
An S&P 500 trade in SPY options and the same trade in SPX options can leave you with very different amounts after tax. Same market view, same holding period, same profit. The difference is a section of the tax code most retail traders have never read.
In the US, broad-based index options such as SPX fall under Section 1256, which taxes gains 60% as long-term and 40% as short-term no matter how briefly you held. SPY options, because SPY is an ETF, do not. Here is how the two compare on tax, settlement, assignment risk and contract size, with the arithmetic.
TL;DR — Quick Summary
30-sec read- 1SPX options are Section 1256 contracts: 60% of any gain or loss is treated as long-term and 40% as short-term, even if you held for one day.
- 2SPY options are ordinary equity options, so a gain on a position held a year or less is taxed entirely as short-term, at your ordinary rate.
- 3On a $50,000 net gain in the 32% bracket, the 60/40 treatment saves about $5,100 in federal tax in the example below (before state tax and any NIIT).
- 4SPX options are European-style and cash-settled, so there is no early assignment and no shares delivered. SPY options are American-style and physically settled.
- 5Section 1256 contracts are marked to market on the last business day of the year, and wash sale rules do not apply to them.

Key Takeaways
6 points- 1Section 1256 applies to regulated futures, many broad-based index options and certain other contracts; it does not apply to options on ETFs such as SPY or QQQ.
- 2The 60/40 split applies to gains and losses alike, so a big losing year is also split 60/40.
- 3A blended federal rate under 60/40 is 0.6 × the long-term rate + 0.4 × your ordinary rate, which is well below the ordinary rate at every bracket.
- 4Index options settle in cash at a value set by the exchange, which removes early-assignment and dividend risk but also removes the option to take shares.
- 5Tax efficiency does not outweigh poor sizing: an SPX contract controls about ten times the notional value of one SPY contract.
- 6Always confirm treatment for your own situation with a qualified tax professional; this article is educational, not tax advice.
What Is a Section 1256 Contract?
Section 1256 of the Internal Revenue Code sets a special tax regime for several kinds of financial contracts. For retail options traders the important category is nonequity options, which includes listed options on broad-based stock indexes. The S&P 500 index (SPX and its weekly SPXW series), the mini-SPX (XSP), the Nasdaq-100 (NDX), the Russell 2000 (RUT) and most cash-settled volatility index options qualify. Regulated futures contracts qualify as well.
What does not qualify: options on individual stocks and options on exchange-traded funds. SPY, QQQ and IWM are ETFs, so their options are equity options, taxed under the ordinary capital gains rules that depend on how long you held the position. The list of qualifying products can change and has edge cases, so check the specific contract against IRS guidance or ask your broker, rather than assuming.
The 60/40 Rule Explained
Under the normal rules, a profit on an option held one year or less is a short-term gain taxed at your ordinary income rate. An active trader holds options for days or weeks, so nearly every gain is short-term. Section 1256 changes that:
Blended federal rate under Section 1256
Blended Rate = 0.60 × Long-Term Rate + 0.40 × Ordinary RateThe split applies regardless of holding period, including positions opened and closed on the same day.
Because the long-term capital gains rate is lower than the ordinary rate at every bracket, the blend is always lower than the ordinary rate you would pay on SPY. The wider the gap between the two rates, the bigger the saving.
$50,000 Net Gain: SPY Options vs SPX Options
Educational ExampleA hypothetical, illustrative example. It uses federal rates only and ignores state tax, the 3.8% net investment income tax, and income thresholds that determine your actual long-term rate.
Two traders each make a $50,000 net gain from short-dated S&P 500 option trades during the year. One uses SPY options, the other SPX options. Federal tax in three illustrative brackets:
| Ordinary / LT rate | SPY (all short-term) | SPX (60/40) blended | SPX tax | Saving |
|---|---|---|---|---|
| 24% / 15% | $12,000 | 18.6% | $9,300 | $2,700 |
| 32% / 15% | $16,000 | 21.8% | $10,900 | $5,100 |
| 37% / 20% | $18,500 | 26.8% | $13,400 | $5,100 |
The 32% row: 0.60 × 15% + 0.40 × 32% = 9% + 12.8% = 21.8%, against 32% flat on SPY. Same $50,000 profit, a difference of $5,100 in federal tax. The saving grows in proportion to your gains, which is why it matters most to frequent, profitable traders.

Year-End Mark-to-Market
The 60/40 rate is not a free lunch; it comes bundled with two other rules.
| Rule | What it means |
|---|---|
Mark-to-market | Open positions are treated as sold at fair market value on the last business day of the tax year, and as repurchased the next day. An unrealized $4,000 gain on December 31 is taxed that year. |
Form 6781 | Gains and losses are totalled on IRS Form 6781, then carried to Schedule D at the 60/40 split. Many brokers report them in a dedicated 1099-B section. |
Wash sales | Wash sale rules generally do not apply, so repurchasing right after a loss does not defer the deduction. |
Loss carryback | Individuals can elect to carry a net 1256 loss back up to three years to offset prior 1256 gains, which can generate a refund. Capital losses on SPY follow ordinary carryforward rules instead. |
The mark-to-market rule cuts both ways. It creates a tax bill on gains you have not yet realized, so keep cash set aside for it. It also means you cannot defer a gain into next year by simply not closing the position. If wash sales are what you are trying to avoid on SPY, see Tax-Loss Harvesting for how that rule works on ordinary securities.
SPX vs SPY Options: Beyond Taxes
Tax treatment is only one of the differences, and not always the deciding one.
| Feature | SPX (index options) | SPY (ETF options) |
|---|---|---|
| US tax treatment | Section 1256: 60% long-term / 40% short-term | By holding period; usually short-term for active trades |
| Exercise style | European: exercisable only at expiration | American: can be exercised any time |
| Settlement | Cash-settled | Physically settled: 100 shares per contract |
| Early assignment risk | None | Real, especially for short in-the-money options before ex-dividend dates |
| Contract notional | Index level × $100, about ten times SPY | SPY price × 100 shares |
| Smaller size | XSP (mini-SPX) is about one-tenth of SPX | Already small and flexible to size |
| Wash sale rule | Does not apply | Applies |
Assignment and Settlement
A short SPY call or put that goes in the money can be assigned early, leaving you with 100 shares per contract you did not plan to hold, which is a particular hazard around dividend dates. That is the mechanism behind many unexpected margin calls in credit spreads and iron condors on ETFs. Because SPX is European-style and cash-settled, none of that exists: you either have a cash credit or debit at expiration, and there are no shares to deliver. Check the contract specifications for whether a given expiry settles at the morning open or the afternoon close, because the standard monthly and the weekly series have historically differed.
Contract Size and Risk
SPX options multiply the index level by $100. With the index at 6,000, one contract controls $600,000 of notional exposure; the equivalent SPY contract controls roughly a tenth of that. A trader who moves from SPY to SPX for the tax benefit and keeps the same contract count has multiplied their risk tenfold. If the account is small, XSP offers index treatment at roughly a tenth of the size, though its liquidity is thinner. Size the position first, using something like the Position Size Calculator, and let the tax treatment break the tie.
Liquidity and Costs
SPY options are among the most liquid in the world, with tight bid-ask spreads on the dollar scale. SPX options are also deep, but each contract is larger, so a one-tick spread represents more dollars, and per-contract exchange fees are often higher. Compare the spread as a percentage of the option price, and include fees, before deciding the tax saving is worth it.

Trade-Offs and Pitfalls
- Losses get the same split. A losing year is also treated 60% long-term and 40% short-term, which can be less favorable than short-term treatment if you could have used the loss against high-rate short-term gains.
- Phantom gains at year end. You owe tax on open positions as if you sold them on the last business day. Plan cash for the bill.
- The saving is federal only. State tax rules vary, and some states do not follow the 60/40 split. The net investment income tax may also apply on top.
- Not every index product qualifies. Narrow-based indexes and ETN or ETF options do not. Verify the contract before relying on the treatment.
- A tax edge does not make a bad trade good. Lower tax on a gain you never earned is worth nothing. Edge first, tax second.
A practical way to use this: if you already trade S&P 500 options at size and your short-term gains are taxed at a high bracket, price the same strategy in SPX or XSP and compare after-tax and after-fee results over a full year.

People Also Ask
Are SPX options taxed differently than SPY options?
Yes. SPX options are Section 1256 contracts, taxed 60% as long-term and 40% as short-term gains regardless of holding period. SPY options are equity options, so gains held a year or less are short-term and taxed at your ordinary income rate. The difference can be several thousand dollars on a profitable year.
What is the 60/40 tax rule for options?
It is the treatment under Section 1256 where 60% of a gain or loss is taxed at long-term capital gains rates and 40% at short-term rates, whatever the holding period. It applies to qualifying contracts such as broad-based index options and regulated futures, and the blended federal rate is 0.6 × the long-term rate plus 0.4 × your ordinary rate.
Does the wash sale rule apply to SPX options?
Generally no. Section 1256 contracts are marked to market at year end and are exempt from the wash sale rule, so you can claim a loss and re-enter the same position. SPY options, being equity options, are subject to wash sale rules if you reacquire a substantially identical position within the 30-day window.
Is SPY or SPX better for options trading?
Neither is universally better. SPX offers favorable US tax treatment, European-style exercise and cash settlement, so there is no early assignment, but each contract is about ten times larger and fees can be higher. SPY offers smaller size and very tight spreads but carries early assignment risk and ordinary short-term tax treatment.
What is XSP and does it get the same tax treatment?
XSP is the mini-S&P 500 index option, sized at roughly one-tenth of SPX. It is a cash-settled, European-style index option and is generally treated as a Section 1256 contract, so it offers the 60/40 treatment at a smaller contract size. Liquidity is thinner than SPX or SPY, so compare spreads before trading it.
Frequently Asked Questions
Do QQQ options get Section 1256 treatment?
No. QQQ is an ETF, so options on it are equity options. The Nasdaq-100 index options (NDX and its weekly series) are the Section 1256 counterpart, and a mini version also exists. Check the specific product before assuming.
Can I use SPX options in an IRA?
Many brokers allow index options in an IRA subject to account approval, but there is no tax benefit from Section 1256 inside a tax-advantaged account because gains are already sheltered or taxed on withdrawal. The 60/40 treatment is relevant to taxable accounts.
How are SPX options reported on my tax return?
Gains and losses on Section 1256 contracts are reported on IRS Form 6781, with the 60% long-term and 40% short-term amounts flowing to Schedule D. Your broker's year-end Form 1099-B typically summarizes the aggregate profit or loss for these contracts, including the year-end mark-to-market on open positions.
Does 60/40 apply if I lose money?
Yes. Net losses are also treated 60% long-term and 40% short-term. Individuals can also elect to carry a net Section 1256 loss back up to three years against prior Section 1256 gains, subject to the rules in the Form 6781 instructions.
Is this tax advice?
No. This is general education about US federal rules as commonly described. Tax rules, qualifying products, state treatment and your own circumstances all matter, so confirm treatment with a qualified tax professional before changing how you trade.
