IRC 1234: Tax Treatment for Options to Buy, Sell, or Write

IRC Section 1234 sets the tax treatment for options to buy or sell property, and it works differently depending on which side of the contract you’re on. If you bought the option, the statute looks through to the underlying property: an option on stock produces capital gain or loss because the stock itself is a capital asset, and your holding period on the option decides long-term versus short-term. If you wrote the option, the statute is less generous. Premium you keep on a lapse, and any gain or loss when you buy the position back to close, come out as short-term capital no matter how long the contract was open.¹

The Look-Through Rule for Buyers

Section 1234(a) ties the character of a buyer’s gain or loss to the character the underlying property would have in that buyer’s hands. Buy a call on publicly traded stock, sell the call at a profit, and the gain is capital because the stock would have been a capital asset to you. If you were a securities dealer holding the same stock as inventory, the gain would be ordinary.¹

The look-through has narrow carve-outs in Section 1234(a)(3) for options that are themselves inventory in a dealer’s hands and for transactions where another Code provision already treats the gain as ordinary. Those exceptions mostly touch professional market makers rather than retail investors.

What Happens When a Buyer Closes the Position

The premium you pay for an option is a capital expenditure, not a deductible expense. The tax outcome depends on how the position ends.²

Selling Before Expiration

Sell a put or call before it expires and the difference between what you paid and what you received is capital gain or loss, assuming the underlying is a capital asset. Long-term or short-term depends on how long you held the option. More than one year gets the preferential long-term rates that top out at 20% for the highest earners; one year or less is short-term and taxed at ordinary rates.³ The holding period starts the day after you buy the option and ends on the day you sell it.

Most exchange-traded equity options expire in weeks or months, so retail option sales generate short-term results as a practical matter. Longer-dated LEAPS contracts are the main place holding past a year is even possible.

Expiration Without Exercise

If the option expires worthless, the statute treats you as having sold it on the expiration date. Your loss equals the full premium paid. Character follows the look-through rule, and long-term versus short-term follows how long you held the option, measured from purchase through expiration.²

Exercising an Option

Exercise is not itself a taxable event on the option. The premium folds into the basis math on the underlying stock:

Exercising a call: the premium is added to the strike to become your cost basis. Pay a $3 premium on a $50-strike call and your basis in each acquired share is $53.²
Exercising a put: the premium reduces the amount realized on the sale. Sell at a $40 strike after paying a $2 premium and your amount realized is $38 per share.²

When you exercise a call, the stock’s holding period starts the day after exercise. Time you held the option does not carry over. Gain or loss on the eventual stock sale depends on how long you held the stock itself.

Why Writers Get Short-Term Treatment

Writers receive premium upfront, but the IRS does not treat that premium as income when it arrives. It sits in a deferred account until the position closes.² When the close comes, Section 1234(b)(1) lumps two scenarios together: an option that expires unexercised, and one you buy back to close. In both, the statute treats the gain or loss as coming from a capital asset held not more than one year, regardless of how long the option was actually outstanding.¹

A writer who collects a premium in January and watches the option expire in December of the following year still reports short-term capital gain. There is no path to long-term treatment through lapse or a closing buy. Since short-term capital gains are taxed at ordinary rates, the writer’s premium income ends up taxed the same way as wages or interest.³

When the Option Is Exercised Against You

Exercise is the one place a writer’s premium can end up inside a long-term outcome, and only indirectly. The premium folds into the stock transaction:

Call exercised against you: the premium is added to the strike to determine your amount realized on the stock sale. Write a $60 covered call for a $4 premium and your amount realized is $64 per share. Long-term or short-term follows how long you held the stock before it was called away.²
Put exercised against you: the premium reduces your basis in the stock you must buy. Write a $45 put for $3 and your basis is $42 per share. The stock’s holding period begins on the purchase date, not the date you wrote the put.²

The premium has no independent tax event when the option is exercised; whatever character shows up does so through the stock sale.

The Protective Put Holding Period Reset

Buying a put to hedge stock you already own is common, and it carries a holding period consequence people miss. The IRS distinguishes between a married put and a protective put based on timing.

Buy the stock and the put on the same day (a married put) and the put does not affect the stock’s holding period. Already held the stock more than a year when you buy the put? Also no effect. The trap is the middle case: you bought the stock less than a year ago, then buy a put on a later day. For as long as the put is open, the IRS resets the stock’s holding period to zero. Once the put expires or is sold, the clock starts over from scratch.²

An investor eleven months into a holding period who buys a protective put for two months, then sells the put, could find the stock needs another full year before qualifying for long-term treatment. If the stock is near the one-year mark and you want protection, waiting until after the anniversary avoids resetting the clock.

Options That Don’t Fall Under Section 1234

Several categories of options sit outside the Section 1234 framework. Reporting them under the wrong set of rules is a common audit issue.

Section 1256 Contracts and 60/40

Broad-based index options (such as options on the S&P 500 index), regulated futures contracts, and foreign currency contracts are classified as Section 1256 contracts. They receive automatic 60/40 treatment: 60% of any gain or loss is long-term capital and 40% is short-term, no matter how briefly you held the position.⁴ Section 1256 also imposes a mark-to-market rule: any open position at year-end is treated as sold at fair market value on the last business day, with gain or loss reported that year and basis adjusted so you’re not taxed twice at the actual close.⁵

Dealer Options and Hedges

A securities or options dealer holds options as inventory. Because inventory is not a capital asset, dealer gains and losses on options are ordinary rather than capital.⁶ Section 1234(b)(3) separately confirms that the short-term rule for writers does not apply to options granted in the ordinary course of a dealer’s business of granting options.¹ Options used as bona fide business hedges against price, interest rate, or currency risk can also produce ordinary treatment, matching the tax character of the underlying income or expense being protected.

Compensatory Stock Options

Employee stock options and other options granted for services are excluded from Section 1234. Those are governed by IRC Sections 61, 83, and 421.⁷ If your employer gave you ISOs or NSOs as part of your pay, the rules on this page are not the ones that apply.

Wash Sales Involving Options

Section 1091 disallows a capital loss when you sell stock or securities at a loss and acquire substantially identical stock or securities within 30 days before or after. The statute specifically covers entering into a contract or option to acquire substantially identical stock within that window.⁸

Sell stock at a loss and buy a call on the same stock within 30 days: wash sale, loss disallowed. Close an option at a loss and buy the underlying stock or a substantially identical option shortly after: same risk. The disallowed loss is not lost forever; it gets added to the basis of the replacement position, deferring the deduction until you eventually close that replacement cleanly.

Straddles and Constructive Sales

Two other Code sections can override or modify the Section 1234 result.

Section 1092 governs straddles: offsetting positions in the same or substantially similar property. It prevents you from recognizing a loss on one leg while keeping the offsetting gain leg open. Any loss on a straddle position is deferred until the day all offsetting positions are disposed of, and the deferred loss is added to the basis of the remaining offsetting positions. Traders who close one side of a spread at a loss while holding the other side open should expect the deduction to wait.

Section 1259 governs constructive sales. If you hold appreciated stock and use options or other instruments to effectively lock in the gain while keeping the position open, the statute may treat you as having sold the stock at fair market value on the constructive sale date, meaning tax now on paper gains. Triggers include a short sale of the same or substantially identical property, an offsetting notional principal contract, and a futures or forward contract to deliver the same property.⁹ A safe harbor avoids constructive sale treatment if you close the hedge within 30 days after the tax year ends and hold the appreciated position unhedged for at least 60 days after that close.

Loss Caps and the Net Investment Income Tax

Net capital losses from option trading are deductible against ordinary income only up to $3,000 per year, or $1,500 if married filing separately. Losses beyond the cap carry forward indefinitely and keep their short-term or long-term character.³ Lose $15,000 on expired options in a year and you can offset only $3,000 of wages or other ordinary income that year; the remaining $12,000 carries to future years.

Gains cut the other way. Capital gains from options count as net investment income for the 3.8% Net Investment Income Tax, which applies to the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly).¹⁰ A strong options year can push you over these thresholds even if salary alone would not.

Where to Report Option Trades

Standard equity options under Section 1234 go on Form 8949, which feeds Schedule D of Form 1040. Your broker will issue a Form 1099-B showing proceeds and often cost basis; Form 8949 is where you reconcile broker figures with what you report.¹¹

Section 1256 contracts go on Form 6781, which handles both the 60/40 split and the year-end mark-to-market valuation before flowing to Schedule D.⁵ Equity options on individual stocks go on 8949. Broad-based index options, futures, and other Section 1256 contracts go on 6781. Trade both and you’ll file both.

Exercised options have no separate line item. The premium paid or received simply adjusts the basis or amount realized on the underlying stock, and that transaction shows up on Form 8949 when the stock is eventually sold.
