Options traders live with a particular kind of tax whiplash: a profitable premium-selling strategy can still owe tax on losses the wash sale rule refuses to let through, and a rough year can still be capped at a $3,000 deduction against everything else you earned. The Section 475(f) mark-to-market election is built to fix exactly that, but options traders face a wrinkle that stock-only traders do not. Your book is rarely just one kind of option, and the election does not treat all options the same way.
What has to be true before an options trader can elect 475(f)?
You have to already qualify for trader tax status before Section 475(f) is available at all, a facts-and-circumstances business determination that works the same way for options traders as it does for stock traders. Our trader tax status pillar guide covers the qualification factors, the election deadline of the unextended prior-year return due date (April 15), the requirement to file Form 3115, and the five-year revocation lock in full detail, so we will not repeat that mechanics here. What that guide does not dig into is what the election actually does once you trade options, and that is where the analysis diverges.
Does the Section 475(f) election cover options trading?
Yes, for equity options. The 475(f)(1) securities election reaches any security as defined in Section 475(c)(2), and that definition includes options on individual stocks and options on exchange-traded funds like SPY, QQQ, and IWM. Once elected, those equity option positions leave the capital-gains world entirely and become ordinary gain or loss reported on Form 4797 instead of Form 8949 and Schedule D.
What the election changes for equity options mirrors what it does for stock: the wash sale rule in Section 1091, which otherwise disallows a loss when you buy a substantially identical option (or, in narrow cases, the underlying) within 30 days before or after, no longer applies. The $3,000 net capital-loss limitation against other income also disappears, so an options trader who churns through repeated stop-outs and re-entries on the same underlying no longer has losses parked behind a wash sale flag or capped against ordinary income.
What happens to open option positions at year end under Section 475?
Every open equity option position the election covers is marked to fair market value on the last trading day of the year and treated as if sold at that price, whether you actually closed it or not. The gain or loss that results is ordinary income or loss for that year, and your basis resets to the marked value going into the next year.
This is where premium sellers need to pay close attention. A short call or put you are still holding on December 31 is marked at whatever it would cost to close that day, and if the premium has decayed in your favor, that unrealized gain is taxed now, in the year you are still short the position, not later when you actually buy it back or let it expire. A trader running a steady short-premium book can end up recognizing income on positions that generate no cash that year, which is a cash flow planning issue even though it is a fair trade for losing the wash sale problem on the loss side.
Do SPX and other broad-based index options get swept into the 475(f) election?
No. Broad-based index options, meaning options on SPX, NDX, RUT, XSP, and similar indexes, are Section 1256 contracts, not securities under 475(f)(1). They are already marked to market every year by statute and taxed under the 60/40 rule regardless of how long you held them, reported on Form 6781 rather than Form 4797.
Two Separate Elections, Not One
Critical- 475(f)(1), the securities election. Covers stock, ETF shares, and equity options (SPY, QQQ, single-name options). This is what most traders mean when they say "I elected mark-to-market."
- 475(f)(2), the commodities election. A separate election required to pull Section 1256 contracts, including broad-based index options like SPX and NDX and regulated futures, into ordinary mark-to-market treatment.
- Electing (f)(1) alone leaves (f)(2) contracts untouched. A trader who elects only the securities election keeps 60/40 treatment on SPX and NDX while equity options become ordinary. Nothing forces the two together, and nothing happens to your index options unless you separately elect (f)(2).
Most options traders who mix single-name or ETF options with broad-based index options elect 475(f)(1) and stop there, on purpose. The 60/40 rule already gives a blended rate below ordinary income tax rates on SPX and NDX positions no matter how short the holding period, so there is rarely a reason to trade that away by adding the commodities election. The two elections are made and revoked independently, so a trader can run equity options through ordinary mark-to-market treatment while SPX and NDX index options keep compounding at 60/40 in the same portfolio, in the same year, under the same trader tax status.
What happens to wash sales and the loss cap for options traders who elect?
For the options the election actually covers, the wash sale rule and the $3,000 cap are both gone, and that combination is usually the entire reason an options trader elects in the first place. High-frequency equity-option trading naturally produces repeated round trips on the same underlying within 30-day windows, which is exactly the pattern the wash sale rule was written to catch, and without the election every one of those disallowed losses gets added back to the basis of the replacement position instead of being deductible now.
The loss cap matters just as much for premium sellers who get caught on the wrong side of a volatility spike. A trader who takes a genuine $150,000 loss on equity options in a bad month, without the election, can deduct only $3,000 of it against other income that year, carrying the rest forward under the ordinary capital-loss carryover rules. With the election, that same loss is fully deductible as ordinary loss in the year it happens and can offset W-2 income, other business income, or create a net operating loss.
Should options traders elect Section 475(f) mark-to-market?
Election makes sense for high-volume equity-option day traders and active premium sellers, particularly those already realizing losses that a wash sale disallowance or the capital-loss cap has been trapping. Traders who already close everything within the same tax year, meaning short-term gains and losses either way, give up no long-term rate by electing, since none of their equity option gains were ever eligible for long-term treatment to begin with.
The election is the wrong move for anyone counting on 60/40 treatment from Section 1256 index options as a meaningful part of their income. Electing 475(f)(2) on top of 475(f)(1) would erase that benefit for no offsetting gain if the trader is not also generating large equity-option losses. It is also wrong for a trader holding LEAPS or other longer-dated equity options for genuine long-term appreciation, because the election converts what would have been a favorable long-term capital gain into ordinary income the moment the position is marked at year end.
Does the mark-to-market election affect self-employment tax or the QBI deduction for options traders?
Self-employment tax is a clear no, which surprises traders who assume ordinary income treatment means self-employment tax follows. Trading gains are not earnings from self-employment under the Internal Revenue Code, so self-employment tax never applies to options trading gains, whether they are capital gains, Section 1256 60/40 gains, or ordinary Section 475 mark-to-market gains. That holds true before and after the election.
The QBI deduction generally does not apply either, though the reasoning depends on which situation you are in. A non-electing trader gets no QBI benefit because capital gains and losses are excluded from qualified business income under Treas. Reg. Section 1.199A-3, and trading is also a specified service trade or business under Treas. Reg. Section 1.199A-5, which disallows the deduction once taxable income clears the SSTB thresholds regardless of trader tax status. For a 475 trader whose gains are ordinary income and whose taxable income stays below those thresholds, whether QBI is available is unsettled among practitioners, so get advice before assuming either answer. What the election does open up, alongside trader tax status itself, is Schedule C treatment for the ordinary and necessary expenses of running the trading business, such as data feeds, platform costs, and a home office, deducted the same way described in the pillar guide.
Bottom Line
Section 475(f) is a genuinely different tool depending on what kind of options you trade. For equity options on individual names and ETFs, the securities election removes the wash sale rule and the $3,000 loss cap and marks open positions to market at year end, which is a strong fit for high-volume traders and premium sellers carrying losses. For broad-based index options like SPX and NDX, the election does nothing unless you separately elect 475(f)(2), and most traders should leave that election alone to keep the 60/40 rate. A trader running both books at once needs the distinction analyzed correctly before filing anything, since the deadline and the follow-up Form 3115 covered in our pillar guide apply regardless of which election you make.
