The Wash Sale is the reporting of a transaction that hasn't been finalized. It will not have a gain or loss reported until it is completely closed.
Your broker's software should keep track of the wash sale and make the basis adjustment as it develops.
When you finally dispose of the underlying stock, and it doesn't fall within the Wash sale window, you will realize the gain, or loss based on the adjusted basis.
The wash-sale rule is an Internal Revenue Service (IRS) regulation that prevents a taxpayer from taking a tax deduction for a loss on a security sold in a wash sale. If you close the Wash Sale in 2023, the profit or loss will be based on the sale price and the adjusted Wash Sale Basis.
