Taxes are the largest single expense most profitable options traders never fully account for. You can run a methodical premium-selling operation, hit your profit targets, and still come out behind your expectations if you have not planned for the tax treatment of your gains. Worse, the IRS rules around options have some counterintuitive wrinkles that trip up even experienced traders every year.

This article covers the core tax treatment of options positions for US retail traders: how short and long-term gains work, the special 60/40 treatment for index options, wash sale rules, what records you actually need to keep, and the signs that you need to be talking to a CPA rather than relying on a tax prep software.

The Basics: How Options Gains Are Taxed

For most retail options trades on individual stocks and equity ETFs, gains and losses are treated as capital gains, just like selling stock. Whether they are short-term or long-term depends on the holding period.

Short-Term Capital Gains

Any option position held for one year or less produces a short-term capital gain or loss upon closing. Short-term gains are taxed at ordinary income rates, which in 2026 can range from 10% to 37% depending on your income bracket.

Because most retail options positions are held for days to weeks, the vast majority of options trading activity generates short-term gains. If you are an active trader with a profitable year, expect to owe at ordinary income rates on most of that profit.

Long-Term Capital Gains

To qualify for long-term capital gains treatment (taxed at 0%, 15%, or 20% depending on income), an options position must be held for more than one year. This is rare in active options trading. The practical relevance is mainly for LEAPS (long-dated calls or puts bought more than a year out) that are then sold at a profit.

When an Option Expires Worthless

If you sold an option and it expires worthless, you recognize the full credit received as a short-term gain in the tax year of expiration. If you bought an option and it expires worthless, you recognize the premium paid as a short-term capital loss in the tax year of expiration.

Exercise and Assignment

When an option is exercised or assigned, the premium received (if short) or paid (if long) generally gets folded into the cost basis of the resulting stock position. The gain or loss on the stock position is then determined when that stock is eventually sold. This creates some record-keeping complexity, particularly if you are assigned on short puts and then hold the resulting stock for some period.

The 60/40 Rule: The Tax Advantage of Index Options

Here is the one area where trading broad index options provides a meaningful tax advantage over equity options: IRS Section 1256 contracts.

What Is a Section 1256 Contract?

Section 1256 covers several categories of financial instruments, including:

  • Regulated futures contracts
  • Foreign currency contracts
  • Non-equity options (broad-based index options like SPX, NDX, RUT)
  • Dealer equity options (in certain situations)

The key characteristic: a broad index option like SPX is a non-equity option and falls under Section 1256.

How the 60/40 Rule Works

Under Section 1256, gains and losses on qualifying contracts are treated as 60% long-term and 40% short-term, regardless of how long you actually held the position. A trade you held for two days on SPX options gets 60% of its gain taxed at the lower long-term capital gains rate.

This means that for a trader in the 37% income bracket with a $100,000 gain on SPX options:

  • Short-term rate on 40%: $40,000 x 37% = $14,800
  • Long-term rate on 60%: $60,000 x 20% = $12,000
  • Total tax: $26,800, or an effective rate of 26.8%

Compare that to the same gain on SPY options (which are equity options and do not qualify for 1256 treatment):

  • Full short-term rate: $100,000 x 37% = $37,000

The difference is real. For active premium sellers who regularly trade index products, moving from SPY options to SPX options can reduce your effective tax rate on gains by 5-10 percentage points.

Mark-to-Market on Section 1256

Section 1256 contracts also require mark-to-market accounting. At the end of each tax year, open Section 1256 positions are treated as if they were sold at their fair market value on December 31, and the resulting gain or loss is recognized. This means you cannot defer gains on open SPX positions into the next year by simply not closing them. The IRS treats them as closed at year-end.

Which Products Qualify?

Qualifying (non-equity, Section 1256):

  • SPX options (S&P 500 cash-settled index)
  • NDX options (Nasdaq-100 cash-settled index)
  • RUT options (Russell 2000 cash-settled index)
  • VIX options
  • Futures options (generally)

Not qualifying (treated as equity options):

  • SPY options (ETF, not an index)
  • QQQ options (ETF)
  • IWM options (ETF)
  • Any individual stock options

Wash Sale Rules and Options

Wash sales are one of the most misunderstood areas of trading tax law. The wash sale rule disallows a capital loss if you buy a “substantially identical” security within 30 days before or after the sale that generated the loss.

The Basic Rule

If you sell a stock or option at a loss and then buy the same (or substantially identical) security within 30 days on either side, you cannot claim the loss in the current tax year. The disallowed loss gets added to the cost basis of the replacement security instead.

How It Applies to Options

The wash sale rule explicitly applies to options. Losing trades on calls or puts and then re-entering similar positions within the 30-day window can trigger the wash sale rule. The complexity is in determining what counts as “substantially identical.”

Clear-cut cases:

  • Selling a losing call on AAPL at the 180 strike and immediately buying a call on AAPL at the 180 strike in the same or next expiration = wash sale.

Gray areas:

  • Selling a losing call at one strike and buying a call at a significantly different strike
  • Selling options on SPY and buying options on QQQ or SPX
  • Selling a stock at a loss and buying calls on the same stock

The IRS has not published definitive guidance on many of these scenarios. High-volume options traders dealing with wash sale questions should get specific guidance from a tax professional.

Section 1256 and Wash Sales

Here is a notable exception: Section 1256 contracts (including qualifying index options) are not subject to the wash sale rule. This is another meaningful advantage of trading SPX over SPY. You can take a loss on SPX options and immediately re-enter without triggering a wash sale disallowance.

What Records to Keep

The IRS requires that you maintain sufficient records to calculate your gains and losses. For options traders, this means more than just your year-end 1099-B.

What to Track for Every Trade

  • Date of trade entry and exit (or expiration)
  • Number of contracts
  • Premium received or paid per contract
  • Broker commission paid
  • Whether the position was opened or closed
  • For assigned positions: cost basis of resulting stock, including option premium

The 1099-B Reliability Problem

Your broker’s 1099-B should report most of this, but brokers are not required to report all cost basis information for options. Complex multi-leg strategies (iron condors, spreads) can have cost basis reporting gaps or errors. Some brokers do not report adjusted cost basis for assigned options correctly.

Do not rely solely on your 1099-B. Maintain your own trade log throughout the year. A simple spreadsheet with the fields above is sufficient for most retail traders. If you use accounting software like TradeLog or a CPA that specializes in traders, you will be in a much stronger position if questioned.

How Long to Keep Records

The IRS standard is three years from the date you filed the return (or two years from when you paid the tax, whichever is later). If you have potentially underreported income, the statute extends to six years. Given the complexity of options tax situations, keeping records for six years is a reasonable conservative approach.

Common Mistakes Options Traders Make at Tax Time

Assuming broker cost basis reporting is correct. Spot-check several trades, particularly multi-leg positions and any trades that resulted in assignment or exercise. Broker errors on complex options reporting are not rare.

Ignoring constructive sales. Certain combinations of long and short positions can be treated as constructive sales, requiring you to recognize gain even though you have not actually closed the position. This most commonly comes up with options combined with stock positions.

Not tracking wash sales during the year. By the time you get your 1099-B in February, it is too late to avoid wash sales that happened throughout the prior year. Set up a simple system to flag potential wash sales as you trade, particularly around year-end loss harvesting.

Treating all index options as Section 1256 without verifying. Not every options product that sounds like an index qualifies. Sector ETF options (XLF, GDX, etc.) are equity options and do not qualify. Verify the specific product before assuming the tax treatment.

Missing estimated quarterly tax payments. If you are profitable trading, you likely owe estimated taxes quarterly (April 15, June 15, September 15, January 15). Failing to pay adequate estimated taxes results in underpayment penalties on top of the final tax bill.

When to Talk to a CPA

Self-prepared taxes are fine for many retail traders with straightforward situations. You need a CPA who specializes in trader taxation if any of the following apply:

  • Your trading generates more than $50,000 in annual gains or losses
  • You have wash sale complications across a large number of trades
  • You are considering making a “trader tax status” election (IRC Section 475 mark-to-market election, which has strict requirements and irreversible consequences if done incorrectly)
  • You have complex multi-year loss carryforward situations
  • You are trading in multiple account types (taxable, IRA, joint account) with positions in the same underlying
  • You received assignment and have carry-over cost basis questions

A good trader-focused CPA will save you more than their fee in most of these situations. Look for CPAs who specifically advertise active trader or day trader tax experience. General tax preparers often lack familiarity with the nuances of options reporting.

Conclusion

Options tax treatment is more complex than most traders realize, but the framework is manageable if you understand it clearly. The core points: most equity options gains are short-term and taxed at ordinary income rates; index options under Section 1256 get the favorable 60/40 split regardless of holding period; wash sale rules apply to options and require active tracking; and your broker’s 1099-B is a starting point, not a final answer.

The single highest-ROI action most active options traders can take for tax efficiency is to evaluate whether their index exposure belongs in SPX-style products rather than ETF options. The tax savings on a profitable year can be substantial. Beyond that, maintain a trade log, pay estimated taxes quarterly, and engage a trader-specialized CPA once your situation reaches any meaningful scale.

Start with a tax checklist for options traders in January of each year, and you will avoid most of the surprises that cost traders real money at filing time.
