Do wash-sale rules apply to options?
Learn when U.S. wash-sale rules can affect option losses, stock losses followed by calls, replacement basis, IRA purchases, and broker reporting.
Direct answer
Yes. U.S. federal wash-sale rules can apply to losses from sales or trades of contracts and options to acquire or sell stock or securities. They can also affect a stock loss when, within 30 days before or after the loss sale, the taxpayer acquires substantially identical stock or securities or a contract or option to buy them. The rule generally postpones rather than erases the loss by adding the disallowed amount to replacement basis, but an IRA or Roth IRA replacement purchase does not receive that basis adjustment. Whether two different option contracts are substantially identical depends on facts and circumstances, so every roll is not automatically a wash sale or automatically safe.
Test the loss and the full 61-day window
Start with a sale, trade, or treated disposition at a loss. Then review the 30 calendar days before the disposition, the disposition date, and the 30 calendar days after it. Purchases before the loss sale count just as purchases after it do.
The replacement can be substantially identical stock or securities, or a contract or option to acquire substantially identical stock or securities. IRS Publication 550 also states that wash-sale rules apply to losses from sales or trades of options to acquire or sell stock or securities. An expired purchased option is treated as sold or traded on its expiration date for general option-loss reporting, so nearby replacement activity must be reviewed rather than ignored.
Same underlying does not answer substantial identity
A new call after selling the underlying stock at a loss can trigger scrutiny because the rule expressly covers acquiring a contract or option to buy substantially identical stock. For an option-to-option roll, compare rights, underlying, call or put direction, strike, expiration, exercise terms, deliverable, and economic relationship.
The tax standard is substantially identical, not merely related and not necessarily identical ticker text. IRS guidance describes the decision as facts-and-circumstances based. Do not claim that changing one strike or expiration always breaks the link, and do not assume that every option on the same stock is automatically a replacement.
A disallowed loss usually moves into replacement basis
For a taxable-account replacement, a disallowed wash-sale loss is generally added to the cost of the replacement stock or securities, and the replacement holding period includes the holding period of the disposed position. This defers recognition until a later disposition rather than allowing the current deduction.
Partial replacement can disallow only the matched portion, so quantities and acquisition order matter. If substantially identical stock is acquired in an IRA or Roth IRA, Publication 550 excludes that replacement from the normal basis increase. The current loss is disallowed without creating usable basis in the retirement account.
Broker reporting is narrower than taxpayer responsibility
Form 1099-B box 1g generally reports a disallowed wash-sale amount for covered securities when the replacement has the same CUSIP and was bought in the same account. That operational reporting scope does not define the full tax rule. Cross-account activity, a spouse's activity, an IRA purchase, stock-to-option replacements, and contracts with different identifiers may not be assembled by one broker.
Maintain a 61-day ledger with trade date, loss amount, account owner, account type, security or contract terms, quantity, and replacement basis. Report applicable adjustments on Form 8949 and consult a qualified tax professional when identity is uncertain or positions span accounts.
Common questions
Does rolling an option at a loss always create a wash sale?
No automatic rule makes every roll a wash sale, but changing the strike or expiration does not automatically prevent one either. The loss contract and replacement must be tested for substantial identity using all facts, including underlying, rights, direction, strike, term, deliverable, and economic similarity. Record both legs and obtain tax advice when the new contract closely replaces the old exposure.
Can buying a call after selling stock at a loss cause a wash sale?
Yes, it can. The statutory framework described by the IRS includes acquiring a contract or option to buy substantially identical stock within 30 days before or after the stock loss. Whether the particular call creates the required substantial identity depends on its terms and circumstances, so the existence of a call is a warning to analyze rather than an automatic conclusion.
Is the wash-sale loss gone forever?
In a normal taxable-account replacement, it is generally deferred: the disallowed loss increases replacement basis and the old holding period carries into the replacement. When the replacement is acquired by an IRA or Roth IRA, the normal basis increase does not apply, so the disallowed loss may not be recovered through the retirement account's basis. Other special facts can also change treatment.
If my broker did not flag a wash sale, can I deduct the loss?
Not necessarily. Publication 550 says a wash-sale loss remains nondeductible even when it is not reported on Form 1099-B. A broker often reports only same-CUSIP replacements in the same account and may not see another broker, spouse, IRA, or related option. Reconcile all relevant accounts and contracts before relying on box 1g.
