Does the Wash Sale Rule Apply to Covered Calls That Get Assigned?

The Short Answer: Yes, But Only in Specific Situations

The wash sale rule can apply to covered calls that get assigned, but it does not automatically trigger every time. The IRS wash sale rule — found in IRC Section 1091 — disallows a loss deduction when you sell a security at a loss and buy back a "substantially identical" security within 30 days before or after that sale. When a covered call gets assigned, the mechanics of how your shares are sold and whether you repurchase them within that 61-day window determines whether you have a problem.

For most covered-call traders who simply let assignment happen and move on, the wash sale rule is a non-issue. The risk shows up when you sell shares at a loss through assignment and then quickly buy back the same stock — or when you write a new covered call on the same stock in a way the IRS could treat as acquiring a substantially identical position.

What the Wash Sale Rule Actually Says

The IRS wash sale rule blocks you from claiming a capital loss if you buy the same or substantially identical security within 30 days before or after the sale that created the loss. The disallowed loss does not disappear — it gets added to the cost basis of the replacement shares. This means you defer the loss, not lose it forever. The rule applies to stocks, bonds, and options. The IRS confirmed in Revenue Ruling 2008-5 that the rule also applies to options transactions, not just outright stock purchases.

FINRA and the SEC both flag wash sales as a common area of confusion for retail investors, especially those who trade options alongside their stock positions. The 61-day window (30 days before the sale, the day of the sale, and 30 days after) is the key number to keep in mind.

How Assignment Works and Where the Loss Comes From

When you sell a covered call and the buyer exercises it, your broker sells your shares at the strike price. That is assignment. Your sale proceeds equal the strike price multiplied by 100 shares per contract, and your cost basis is whatever you originally paid for the stock.

Here is a concrete example. Suppose you bought 100 shares of AAPL at $195 per share in January. In March, AAPL drops to $168. You decide to sell a covered call with a $170 strike expiring in four weeks, collecting $2.50 per share ($250 total premium). The stock bounces to $171 at expiration and your call gets assigned. Your effective sale price is $170 strike plus $2.50 premium already collected, so $172.50 per share. Your cost basis was $195. You realize a loss of $22.50 per share, or $2,250 on the position.

If you do nothing after that — no repurchase of AAPL within 30 days — you claim the $2,250 loss on your taxes with no wash sale issue. Simple. The problem starts if you buy AAPL back within that 30-day window.

Three Scenarios Where the Wash Sale Rule Bites Covered-Call Writers

**Scenario 1: You repurchase the same stock within 30 days.** Continuing the AAPL example above — if you get assigned on March 15 at a $2,250 loss and then buy 100 shares of AAPL again on March 30, the wash sale rule kicks in. Your $2,250 loss is disallowed and added to the cost basis of your new shares. You now own AAPL with a cost basis of $195 + $22.50 = $217.50 per share instead of the current market price.

**Scenario 2: You write a deep in-the-money put on the same stock within 30 days.** The IRS treats certain option contracts as substantially identical to the underlying stock. Writing a deep in-the-money put on AAPL shortly after an assigned covered call loss could be viewed as acquiring a substantially identical position, triggering the wash sale rule. The Options Industry Council (OIC) specifically notes that in-the-money options on the same security can be considered substantially identical for wash sale purposes.

**Scenario 3: You hold shares in multiple accounts.** If you get assigned in your taxable brokerage account and your spouse or your IRA buys the same stock within the 30-day window, the wash sale rule still applies. The IRS looks across accounts in the same household. This catches many retail investors off guard. Your broker may not catch cross-account wash sales automatically — the IRS expects you to track this yourself.

The Honest Risk Picture: What Can Go Wrong

The wash sale rule does not cost you money permanently — it defers a loss. But deferral has real costs. If the disallowed loss gets pushed into the next tax year, you lose the time value of that deduction. If you keep trading in and out of the same position, losses can keep getting deferred and your cost basis can become a tangled mess that is hard to unwind at tax time.

The bigger risk is simply not knowing the rule applies. Many retail covered-call traders assume that because they are selling calls on stock they already own, options tax rules do not affect them. That is wrong. The IRS does not give covered-call writers a pass just because the option was part of an income strategy.

There is also a qualified covered call exception under IRC Section 1092 that can affect how long your holding period is treated when you write a covered call. If the call you sell is not a "qualified covered call" — meaning it is too deep in the money or has too short a term — the IRS can suspend your holding period on the underlying shares while the call is open. This matters if you are trying to qualify for long-term capital gains rates. The IRS defines a qualified covered call as one that is not deep in the money and has more than 30 days to expiration, among other criteria.

For Canadian investors, the Canada Revenue Agency (CRA) has its own superficial loss rules under the Income Tax Act that work similarly to the IRS wash sale rule. If you repurchase the same or identical shares within 30 days before or after a loss sale, the CRA disallows the loss and adds it to your adjusted cost base. The CRA's superficial loss rules apply to options as well.

How to Avoid Wash Sale Problems With Covered Calls

The cleanest way to avoid a wash sale issue is to wait at least 31 days after an assignment that produced a loss before buying back the same stock or writing a new option on it. That gives you a clear window outside the IRS's 61-day lookback period.

If you want to stay invested in the sector but avoid the wash sale clock, consider buying a similar but not substantially identical security. For example, if you were assigned on AAPL at a loss, you could buy an ETF like QQQ or XLK for 31 days to maintain tech exposure without triggering the wash sale rule. These are not the same security as AAPL, so the IRS does not treat them as substantially identical.

Keep detailed records. Your broker's 1099-B will flag wash sales it detects within the same account, but it will not catch cross-account or cross-spouse situations. Use a spreadsheet or tax software that tracks options alongside stock positions. If your covered-call activity is frequent, consider working with a CPA who understands options taxation — the IRS rules in this area are detailed and the cost of a mistake is real.

Quick Reference: Wash Sale Rule Checklist for Covered-Call Traders

Before you act after an assignment, run through this list:

1. Did the assignment produce a loss? If no loss, no wash sale issue. 2. Are you planning to buy back the same stock within 30 days? If yes, the loss will be disallowed. 3. Are you writing a new deep in-the-money put on the same stock within 30 days? This may also trigger the rule. 4. Does your spouse or your IRA hold or plan to buy the same stock? Cross-account purchases count. 5. Are you in Canada? Check the CRA's superficial loss rules — they work similarly but have their own details. 6. Is the covered call you sold a qualified covered call under IRC Section 1092? If not, your holding period on the shares may be suspended.

When in doubt, wait 31 days. The tax deferral cost of a wash sale is real, and the record-keeping headache is worse.

Does getting assigned on a covered call automatically trigger the wash sale rule?

No. Assignment by itself does not trigger the wash sale rule. The rule only applies if you sell shares at a loss through assignment and then buy back the same or substantially identical security within 30 days before or after that sale. If you walk away from the position after assignment, there is no wash sale issue.

What counts as a substantially identical security for covered-call traders?

The IRS has not published a precise definition, but the Options Industry Council (OIC) notes that deep in-the-money options on the same stock are generally considered substantially identical to the stock itself. Buying back the exact same stock is the clearest trigger. ETFs that track a broad index are typically not considered substantially identical to a single stock like AAPL or MSFT.

Can I write a new covered call on the same stock right after assignment without triggering a wash sale?

Writing a new at-the-money or out-of-the-money covered call on the same stock after an assignment loss is generally not considered acquiring a substantially identical position, because the option itself is not the same as owning the stock outright. However, writing a deep in-the-money call or put could be viewed differently by the IRS. When in doubt, consult a tax professional familiar with IRC Section 1091.

Does the wash sale rule apply to covered calls in an IRA or TFSA?

In the US, losses inside a traditional or Roth IRA are not deductible anyway, so the wash sale rule has limited direct impact inside the IRA itself. However, if you sell stock at a loss in a taxable account and your IRA buys the same stock within 30 days, the IRS disallows the loss in your taxable account — and the disallowed amount cannot be added back to the IRA's cost basis. Canadian investors should check CRA guidance on superficial losses involving registered accounts like TFSAs and RRSPs.

How does my broker report wash sales from covered calls on my 1099-B?

Your broker is required to report wash sales on Form 1099-B for transactions within the same account and the same security. The 1099-B will show the disallowed loss amount in Box 1g. However, brokers are not required to track wash sales across different accounts or between spouses, so you are responsible for identifying those situations yourself and reporting them correctly on Schedule D.

Does Canada's superficial loss rule work the same way as the US wash sale rule for covered calls?

The CRA's superficial loss rule under the Income Tax Act is similar in structure — it disallows a capital loss when you or an affiliated person repurchases the same or identical property within 30 days before or after the sale. The disallowed loss is added to the adjusted cost base of the repurchased shares. The CRA applies this rule to options as well as stocks, so Canadian covered-call traders face the same basic risk as their US counterparts.
