Will buying this stock back within 30 days trigger a wash sale?

How this is calculated

• The wash sale rule disallows a loss deduction if you buy the same security, or one that is substantially identical (including many options on that security), within 30 calendar days before or after the sale date.
• This tool measures the calendar-day distance between your two dates. A distance of 30 days or less in either direction counts as inside the window.
• If a wash sale applies, the disallowed loss is not gone. It is generally added to the cost basis of the new position, deferring the loss instead of eliminating it.
• The wash sale rule applies across all of your accounts, including IRAs, and can apply to a spouse's accounts on a joint return. It is not limited to a single brokerage.
• "Substantially identical" is a judgment call the IRS and courts apply case by case. Two different companies in the same sector are not automatically substantially identical, but options, warrants, and some ETFs tracking the same index can be.
