Covered Call Wash Sale Rule Explained With Examples

Back in 2008, I watched my account take a hit that would have ended most traders. I had positions that went against me, and like a lot of people, I kept thinking they’d come back. They didn’t. That experience forced me to build something different: a system with rules, with circuit breakers, with an understanding that what you don’t know about taxes and mechanics can cost you more than a bad trade. The covered call wash sale rule is exactly that kind of trap. It sits there, quiet, until you step in it.

I have been trading covered calls since before most of today’s “experts” knew what an option was. I taught my own stockbroker how these worked when I was still in college. And I can tell you this: the wash sale rule is one of the most misunderstood elements in the entire strategy. Not because it’s complicated, but because it operates in a way that feels counterintuitive. You still own the stock. You haven’t “sold” it. Yet the IRS may say you triggered a wash sale anyway. Let me walk you through how this actually works, with real numbers, so you don’t learn it the hard way.

What the Wash Sale Rule Actually Says

The wash sale rule exists to stop taxpayers from selling a security at a loss, claiming the tax deduction, and then immediately buying it back. The classic version is simple: sell Stock A at a loss on Monday, buy Stock A back on Tuesday, and the IRS disallows your loss deduction. The loss gets deferred, added to your cost basis in the new shares.

Where this gets interesting for covered call writers is the “substantially identical” test. The IRS has long held that buying a call option can trigger a wash sale if you sold the underlying stock at a loss. But here’s what catches people: selling a deep in-the-money covered call can also trigger the rule, because that call is so intrinsically valuable that it’s effectively the same economic position as owning the stock.

I have seen traders get blindsided by this. They take a loss on a position, immediately sell an in-the-money call to “work the position,” and come tax season discover their loss deduction vanished. The IRS Publication 550 spells this out, but most people don’t read it until after the fact.

The Covered Call Twist: When Selling Options Becomes a Problem

Most covered call sellers think about wash sales from the buy side. They worry about repurchasing shares. But the real risk is on the sell side of the call itself. When you sell a call that is deep in the money, you have created a position with very little time value and very high delta. It moves almost dollar-for-dollar with the stock. The IRS looks at this and says: that’s substantially identical to owning the stock.

Here is where I draw my line in practice, and where I teach my students to draw theirs. I generally will not sell a call with more than 70 delta, and I prefer to stay under 60. Once you get into the 80s and 90s, you are no longer really selling covered calls for income. You are effectively closing your stock position with extra steps, and the tax code treats it that way.

The covered call strategy I teach at Cash Flow Machine is built around out-of-the-money and slightly in-the-money calls with healthy time premium. That serves two purposes: better income economics, and staying clear of this wash sale territory.

Three Scenarios That Trigger the Rule

Let me give you concrete examples. These are simplified but they capture how the rule actually applies.

Scenario One: The Deep ITM Replacement. You bought XYZ at $100. It drops to $80. You sell the $60 call expiring in two weeks for $20.50. That’s almost all intrinsic value. You have effectively locked in your $20 loss on the stock, but you still hold the shares. If you had sold the stock at $80, you would have a $20 realized loss. By selling that deep call instead, the IRS may treat it as if you sold the stock and bought a “substantially identical” position. Wash sale triggered. Your $20 loss gets deferred.

Scenario Two: The 30-Day Window. Same setup: XYZ at $100, drops to $80, you sell at $80 and take the $20 loss. Ten days later, you buy XYZ back at $82 and immediately sell the $75 call. Classic wash sale on the stock repurchase. But also, because you sold that in-the-money call so quickly, you have added complexity. The call sale itself may be scrutinized if it is deep enough in the money.

Scenario Three: The Rolling Disaster. This is where I see people get hurt repeatedly. You have a covered call position, the stock drops, you buy back the call (at a profit on the option, but the stock is down), and you immediately roll down to a lower strike that is now deep in the money. You think you are managing the position. The IRS sees a loss on the stock (unrealized, but if you had sold) and a deep call that replaces that economic exposure. If you had actually sold the stock at the lower price, then rolled, you have a textbook wash sale.

The key insight: the wash sale rule looks at economic substance, not just legal form. When your call has 90 delta, you do not really own the stock anymore in any meaningful way. You own a synthetic bond that pays stock returns.

How to Stay Clean: Practical Rules I Follow

After fifty years in markets, I have developed a simple framework for avoiding this mess. These are not the only ways to handle it, but they are the ways that let me sleep at night and keep my tax preparer happy.

First, I avoid deep in-the-money calls entirely. My system at Cash Flow Machine on YouTube focuses on strike selection that captures time premium. If I cannot get at least 20% of the option’s value from time decay, I am not interested. That naturally keeps me away from the 80+ delta zone where wash sales live.

Second, if I take a loss on a stock, I wait thirty-one days before selling any call against it. Full stop. No exceptions. I might sell a call on a different stock. I might sit in cash. But I do not create the “substantially identical” position that invites scrutiny.

Third, I track adjusted basis religiously. When a wash sale does occur, the disallowed loss gets added to your cost basis in the replacement shares. It also gets added to the basis of any call option that triggered the rule. This affects your future gain/loss calculations. You need good records, because your broker’s 1099-B will not always get this right.

What Happens to Your Tax Return

When the wash sale rule applies, your loss does not disappear. It gets deferred. The $20 loss from our earlier example becomes part of your new cost basis. If you bought replacement shares at $82, your new basis might become $102. When you eventually sell those shares, that deferred loss reduces your gain or increases your loss.

For covered calls specifically, if the call itself was the replacement property, the disallowed loss gets added to the call’s premium for basis purposes. This creates a tracking headache. You need to know what portion of your original stock loss was deferred, what your new stock basis is, and what your adjusted call basis is.

I am not a tax preparer, and this is not tax advice. But I will tell you what I do: I keep a spreadsheet. Every position, every adjustment, every wash sale calculation. My CPA thanks me for it. The IRS, if they ever ask, gets clear documentation.

Does selling a covered call always create a wash sale risk?

No. Only deep in-the-money calls, typically with delta above 70 or 80, create this exposure. Out-of-the-money and modestly in-the-money calls with substantial time premium do not trigger the rule. The economic substance matters more than the label.

How do I know if my call is “substantially identical” to the stock?

Look at delta. A call with 90 delta moves almost exactly like the stock. A call with 50 delta moves half as much and has significant time value. The higher the delta and the lower the time premium, the more likely the IRS will treat it as substantially identical. When in doubt, assume the stricter interpretation.

Can I recover a disallowed wash sale loss?

Yes, eventually. The loss gets added to your basis in the replacement property. When you finally sell that property without triggering another wash sale, the deferred loss reduces your gain or increases your loss. It is a timing issue, not a permanent denial. But poor tracking can cause you to lose track of what you are owed.

The covered call wash sale rule is not here to trap honest traders. It is here to stop people from gaming the tax code. Understand the line, stay on the right side of it, and you keep more of what you earn. That is what a system is for.

If you want to see how I build positions that generate income without stepping into these tax traps, my Options Mentorship program walks through the complete framework: strike selection, risk management, and yes, the practical tax awareness that separates professionals from amateurs.
