Capital Gains on Covered Calls

The tax treatment of capital gains on covered calls is surprisingly nuanced: the premium you receive is not immediately taxed as income, but the way the position unwinds—exercise, expiration, or assignment—determines whether your gain is short-term or long-term, and can even reset your holding period for the underlying stock.

How premium is initially treated

When you write a covered-call, the premium you receive is not wages, dividends, or ordinary income. It is part of the proceeds of your eventual transaction—either the sale of the stock via assignment, or income from expiration.

This is a critical distinction. Many writers mistakenly believe the premium is taxable immediately as short-term income. It is not. The premium sits, unrecognized, until the position is closed.

Think of it this way: you own 100 shares of a stock and sell a call option. You receive $200 in premium. That $200 does not show up on your 1099 or as ordinary income in April. Instead, it is part of the calculation of your capital gain when the position ends.

Assignment and long-term capital gains

The most common outcome is assignment. Your shares are called away at the strike price, and the transaction closes. Your proceeds equal the strike price plus the premium you collected.

Your [capital-gains-on-covered-calls](capital gain or loss) is calculated as:

Gain = (Strike Price + Premium + Any Other Income) − Original Purchase Price

The character of that gain—whether it is short-term or long-term—depends on how long you held the stock, not how long the option was outstanding.

Suppose you bought 100 shares of XYZ at $50 a share, held it for 14 months, then sold a 30-day call for a $200 premium, strike $60. If assigned, your total proceeds are ($60 × 100) + $200 = $6,200. Your gain is $1,200. Because you held the stock for more than a year, this is a long-term-capital-gain-tax, taxed at favorable rates (0%, 15%, or 20%, depending on income).

If you had bought those shares only 6 months prior to assignment, the same $1,200 gain would be short-term capital gains, taxed as ordinary income at rates up to 37%.

The timing of the call is irrelevant to this calculation. A 30-day call or a 6-month call makes no difference. Your holding period is measured from purchase to assignment.

Expiration and the short-term gain

If the covered-call expires worthless (stock price stays below strike at expiration), you keep the stock. The premium, $200, becomes a short-term capital gain. You realize that profit immediately and must report it, but the stock remains yours with its original holding period intact.

In the example above, if XYZ stock falls to $55 at call expiration, the call expires, you pocket the $200 premium as a short-term gain, and you still own the stock with its 14-month holding period. You have converted part of your upside into a short-term gain while retaining long-term upside potential.

This is a deliberate trade-off. By capping your upside, you generate immediate short-term income. If you later sell the stock at a profit, that additional gain might be long-term, offsetting the short-term premium gain in your overall tax picture.

Early exit and wash-sale complications

Suppose you sell the covered-call for a profit before expiration. If the call is trading for $50 and you bought it back for $50 less, you have a $50 gain on the option. That is treated as a short-term capital gain, regardless of how long you held the call.

But things get complicated if you close the call at a loss. If you bought the call back for more than you sold it for, you have a short-term capital loss. That loss can offset other gains, but it also triggers wash-sale risk if you repurchase a call on the same or similar stock within 30 days.

Similarly, if you sell your stock early—before the call is assigned—you are realizing your capital gain on the stock. That gain’s character depends on your holding period. The premium is factored in as additional proceeds.

The holding-period reset myth

A common misconception is that assignment of a covered call resets your holding period on the stock. This is false. Once your shares are called away, you no longer own them, and there is nothing to reset. Your holding period for that position ended at assignment.

However, if you immediately buy 100 shares of the same stock post-assignment, that is a brand-new position with a brand-new holding period clock. Some investors confuse this with a holding-period reset.

If you want to continue a long-term holding period without interruption, you must not write calls that are likely to be assigned, or you must accept that assignment ends the position.

Tax-loss harvesting and covered calls

Some investors use covered-calls to harvest tax losses. You own a losing position, sell a call to collect premium, and hope the call expires so you can claim the loss while capturing some income from the call.

But be careful: if the stock drops and the call expires, you have a capital loss on the stock (deductible against gains) and a short-term capital gain from the expired call. The net may be favorable, but you must track both legs separately on Form 8949.

Additionally, if you buy back the stock within 30 days of realizing the loss, the wash-sale rule disallows the loss. Writing a call does not prevent wash-sale; the purchase of replacement shares does.

Reporting and documentation

When a covered call is assigned, your broker reports the transaction as a stock sale on Form 1099-B. The proceeds include both the strike price and the premium. You must then determine your cost-basis in the stock—typically purchase price per share—and calculate the gain.

Use Form 8949 to list each covered-call assignment and any expiration or closing transactions. Transfer the totals to Schedule D and then to Form 1040.

If your covered call is assigned and you immediately buy back the same stock, be extremely careful not to trigger a wash sale if there is an unrealized loss from your original purchase date to the assignment date. The IRS has issued guidance allowing covered-call assignment to avoid wash-sale complications in some cases, but documentation is essential.
