0DTE Options Tax Treatment: Section 1256 and What You Owe

Taxes are the hidden cost that can turn a profitable 0DTE strategy into a mediocre one. The difference between SPX and SPY taxation alone can amount to thousands of dollars per year. Here's what you need to know.

SPX Options: The Section 1256 Advantage

SPX options (including 0DTE) are classified as Section 1256 contracts under the IRS tax code. This gives them a unique tax treatment:

60% of gains are taxed as long-term capital gains, 40% as short-term — regardless of how long you held the position.

For a 0DTE trade that lasts 4 hours, 60% of your profit is taxed at the long-term rate (0%, 15%, or 20% depending on your bracket).

The Math

| Taxable Income | Short-Term Rate | Blended 1256 Rate | Savings per $10,000 profit | $50,000–$95,00022%16.8%$520 $95,000–$190,00024%18.0%$600 $190,000–$365,00032%22.8%$920 $365,000–$462,00035%24.6%$1,040 | $462,000+ | 37% | 25.8% | $1,120 |

A full-time 0DTE trader making $80,000/year in the 32% bracket saves roughly $7,360 annually by using SPX instead of SPY. Over a decade, that's $73,600 — before compounding.

SPY Options: Standard Short-Term Capital Gains

SPY 0DTE options are taxed as ordinary short-term capital gains since you hold them for less than one year (obviously — you hold them for hours). Every dollar of profit is taxed at your regular income tax rate.

There's no special treatment, no 60/40 split, no advantage. SPY 0DTE profits sit on your tax return alongside your salary.

Wash Sale Rules and 0DTE

The wash sale rule prevents you from claiming a loss if you buy a "substantially identical" security within 30 days before or after the loss. For 0DTE traders, this creates a potential issue:

Scenario: You lose $500 on a SPY $545 put spread on Monday. On Tuesday, you sell a SPY $545 put spread again (same strike). The IRS could argue this triggers a wash sale, disallowing your Monday loss.

The reality: Wash sale enforcement on options is inconsistent and debated. Most brokers track wash sales at the individual option level (same strike, same expiration). Since 0DTE options have unique daily expirations, a Monday SPY $545 put and a Tuesday SPY $545 put are technically different securities.

Best practice: Track your own wash sales conservatively. If you're trading similar strikes daily, consult a tax professional familiar with options.

SPX advantage: Because SPX is a Section 1256 contract, wash sale rules technically don't apply. Losses are fully deductible in the year they occur, and the entire portfolio is marked to market at year-end.

Mark-to-Market Election (Section 475)

Active 0DTE traders can elect trader tax status (TTS) and use Section 475 mark-to-market accounting. This offers several benefits:

  • No wash sale limitations (for SPY options too)
  • Losses are ordinary losses, deductible against any income (not limited to $3,000/year capital loss limit)
  • Trading expenses are fully deductible (software, data, home office, education)

    • The catch: you must qualify as a "trader" (not an "investor"), and you must make the election by April 15 of the tax year. The IRS looks at trading frequency, time commitment, and intent to profit from short-term market moves. Daily 0DTE trading generally qualifies.

    Tax-Efficient 0DTE Practices

  • Use SPX for your primary strategy. The 60/40 tax treatment saves real money.
  • Track every trade. Use your broker's tax documents, but verify them. Brokers occasionally miscategorize Section 1256 contracts.
  • Consider TTS election if you trade 4+ days per week and spend 4+ hours per day on trading activities.
  • Make quarterly estimated tax payments. 0DTE trading income isn't withheld. Underpayment penalties add up.
  • Harvest losses strategically. If you have a losing month, realize the losses to offset other gains.

    • What to Tell Your Accountant

    Many CPAs aren't familiar with Section 1256 or trader tax status. When you meet with your tax professional, bring:

  • A full trading log (P&L by date and underlying)
  • Broker 1099-B showing Section 1256 contracts separately
  • Documentation of your trading schedule and time commitment
  • A clear statement of whether you want to elect TTS/475

    • If your accountant isn't sure how to handle SPX 0DTE taxes, consider a specialist like Green Trader Tax or a CPA who works primarily with active traders.
