Can you lose money on a covered call?

Yes. The premium only offsets the first part of a fall in the shares. If the stock drops below your purchase price minus the premium, you are losing money, and the loss grows with every dollar the stock falls from there, just as it would if you owned the shares with no call.

How is covered call premium taxed?

Under IRS Publication 550, the premium is not taxed when you receive it. If the call expires, it becomes a short-term capital gain. If the call is exercised, it is added to the sale proceeds of the shares, and the stock's holding period decides long or short term. Buying the call back produces a short-term gain or loss.

What happens if the stock is above the strike at expiration?

The call is normally exercised and your 100 shares are sold at the strike price. You keep the premium and the gain up to the strike, and give up anything above it. If you want to keep the shares, you can buy the call back before expiration, at whatever it costs by then.

Covered Call: Payoff, Breakeven, Assignment and Taxes

Sell to open, 1 contract, the 32 call, limit $0.75. The shares are already in the account: 100 of them, bought at $30. The order fills, $75 lands in cash, and you’ve promised to hand those shares over at $32 if the call’s owner asks for them before it expires. Everything else about the trade follows from that ticket.

How the contract is built

Listed stock options are standardized. Cboe’s equity options product specifications, checked on October 13, 2026, put the unit of trade at generally 100 shares of the underlying stock and quote premiums in points, with one point worth $100. A call quoted at $0.75 therefore pays $75 for the contract. One contract needs 100 shares behind it to count as covered. Own 250 shares and you can cover two calls. The odd 50 stay uncovered.

That lot size shapes a small account. Writing calls across several holdings means owning each one in blocks of 100, which can push a portfolio toward fewer and larger positions than you’d otherwise hold, and that concentration deserves a hard look against the diversification math in how many stocks should you own.

The same specifications cover options on exchange-traded funds, so a call can be written on a fund as readily as on a single stock. Not every fund has listed options. Check the chain before planning calls on a fund from the gold ETF list or anywhere else.

The trade can end a few ways. The call expires worthless and you keep the shares and the premium. The call is exercised and your shares go out at the strike. Or you buy the call back first.

Maximum profit, breakeven and the loss on a fall

The maximum is fixed on the day you sell. The stock can finish at $32 or at $50 and the result is the same $275, because above the strike the call you sold gains whatever the shares gain from there.

Below the breakeven you lose. The shares carry the whole downside, and the premium is a fixed cushion that never grows as the stock falls, so a drop from $30 to $27 costs $300 on the stock with $75 of it recovered, and a drop to $20 costs $1,000 with the same $75 recovered. The covered call calculator runs these sums for your own strike and premium.

When a covered call fits

The trade pays best when the stock drifts. Flat or slowly rising prices let the call run out worthless while the shares hold their value, and the premium becomes a return the stock would never have paid you on its own.

Two markets hurt it. A sharp rally stops you at the strike while an unhedged holder keeps going. A steep fall hands you nearly the full loss, less a small rebate.

Premium size follows time and volatility. A call with more weeks to run, or on a stock that swings hard, pays more, since the buyer is paying for a wider range of outcomes before expiration and the writer is being paid to absorb them. That bigger check is also a warning. A large move either way is where a covered call does worst.

Strike choice sets the balance. A strike close to the current price pays more and leaves little room before the cap bites, while a strike far above it pays little and caps you only after a big run. If you’d be glad to sell at the strike, the trade fits. If not, go higher or skip it.

Assignment and early exercise

Cboe’s specifications, checked the same day, list US equity options as American style: the owner may exercise on any business day up to and including the expiration date. Most assignments still arrive at expiration, when the stock finishes above the strike. Early ones cluster around ex-dividend dates. A call owner who exercises before the stock goes ex-dividend receives the shares in time to collect the payout, and when that dividend is worth more than the time value left in the call, exercising early is the better trade for the owner, which means the writer can lose the shares and the dividend in a single notice.

To keep the shares, buy the call back before it’s exercised. Many traders then sell a new call at a later expiration or a higher strike, a move called rolling. Rolling costs whatever the old call is worth at the time. On a stock that has run well past the strike, that buyback can wipe out the premium you collected and more. The wheel strategy treats assignment as one step in a cycle. It pairs covered calls with puts sold to buy the shares back.

Where it shows on the option chain

Find the expiration you want and the call side. Each strike shows a bid and an ask. When you sell, the bid is what a buyer is paying right now, so a covered call priced at the bid should fill, while a limit between the bid and the ask may fill or may sit. In the example, $0.75 is the bid on the 32 call. The ask is what you’d pay to buy that call back. It matters once you want out of the call and still want the shares.

The chain also shows how far each strike sits from the stock price. Strikes below it are in the money and already carry intrinsic value. Strikes above it are out of the money. Their price is all time value, which bleeds away as expiration nears.

How the IRS taxes a covered call

The premium isn’t income on the day it arrives. IRS Publication 550 for the 2025 tax year, in the web edition the IRS last reviewed or updated on April 30, 2026, says to hold it aside until the obligation ends, and the way it ends sets the treatment:

Expiry makes it a short-term capital gain, however long the call was open.
If the call is exercised, the premium is added to what you received for the shares, and the stock’s own holding period decides whether that gain is long or short term.
Buy it back, and the difference is a short-term gain or loss.

The strike matters too. Publication 550 sets out a “qualified covered call” test: the option trades on a national securities exchange, it is written more than 30 days before expiration, and it is not deep in the money. Calls written after July 28, 2002 also need an expiration no more than 12 months out, unless they meet benchmark rules the IRS publishes separately.

Take a hypothetical stock that closed at $48.30 the day before you write a 60-day call, with strikes listed at $40, $45 and $50, and because the call runs less than 90 days the benchmark is the highest strike under that close. That’s $45. A $45 call qualifies, and a $40 call is deep in the money.

Failing the test makes the stock and the call a straddle for tax purposes, and under the loss deferral rules a loss on one side can be held back while the other side stays open. Passing it has a catch of its own when the strike sits below the stock price: the days you spend as the writer of the call don’t count toward the stock’s holding period, which can leave a gain you expected to be long term stuck in short-term territory.

Dividends get pulled in as well. Among the days Publication 550 says you can’t count toward the qualified-dividend holding period are days on which you had granted an option to buy substantially identical stock, so a call written across the dividend window can change how that payout is taxed. Situations differ, so take a specific position to a tax preparer.

Trades inside a traditional IRA skip this sorting. Withdrawals are taxed when they come out. Shares called away there leave cash that can cover a required minimum distribution without selling something else.

What people get wrong

The biggest error is treating the premium as protection. It covers $0.75 a share. After that, a covered call on a stock that falls hard loses almost as much as the stock does.

Another is forgetting that the cap is real. If the stock jumps to $40 on news, the position still makes $275, and watching the shares leave at $32 is the deal you signed.

Then there’s selling calls on shares with a large unrealized gain in a taxable account. If they’re called away, the whole gain is realized that year, and an in-the-money call may have paused the clock that decides how it’s taxed.

Dividend payers bring their own timing questions, and covered calls on dividend stocks works through the ex-date problem in detail.

A buy-write is buying the shares and selling the call in one order. The strike is the price you agree to sell at. Assignment is the notice that the call has been exercised against you. The call’s delta is a rough gauge of the odds it finishes in the money, and so of assignment.
