Wash Sale Disallowed Category

[SeattleMom]

On my Fidelity Form that lists stock sales, under some of the sales there is a number in Column 1g - Wash Sale Loss Disallowed, which reduces my loss and/or increases my gain.  What is this and why do I have it?  Thank you!

A wash sale is a sale where a stock is sold at a loss and then the same stock is purchased within 30 days.  The loss isn't allowed if you do that.
