Options taxation
Options taxation covers how gains and losses on options contracts are taxed. Most options that are closed or expire produce short-term capital gains or losses, while exercised options adjust the cost basis or sale proceeds of the underlying stock.
Options taxation follows a simple principle: an option by itself is a capital asset, so trading it produces capital gains and losses. Because most listed options expire in a year or less, these gains and losses are usually short-term, taxed at ordinary income rates. Longer-dated options such as LEAPS can qualify for long-term treatment if held for more than 12 months.
When an option is closed or expires, the math is straightforward. A buyer who sells an option, or lets it expire worthless, has a gain or loss equal to the difference between the premium paid and the amount received (zero at expiration). A writer who keeps the premium on an expired option recognizes it as a capital gain at expiration.
Exercise works differently — the option's premium folds into the stock transaction rather than being taxed separately. A call buyer who exercises adds the premium paid to the stock's cost basis. A call writer who is assigned adds the premium received to the sale proceeds. A put buyer who exercises subtracts the premium from the proceeds of the stock sale, and an assigned put writer subtracts the premium received from the cost basis of the stock purchased.
Options taxation appears on the Series 7 exam, which tests premium treatment at expiration, closing, and exercise, and on the Series 9 exam, where supervisors of options sales activity are expected to understand the tax consequences of the strategies they approve.
Key takeaways
- Options gains and losses are capital gains and losses, and most are short-term because listed options typically expire within a year.
- An expired option produces a loss of the full premium for the buyer and a gain of the full premium for the writer.
- Exercise is not a separate taxable event for the option — the premium adjusts the stock's cost basis or sale proceeds.
- Call buyers add the premium to cost basis; put buyers subtract it from sale proceeds; writers adjust in the mirror-image direction.
- The Series 7 and Series 9 exams both test how premiums are treated at expiration, closing, and exercise.
