Hello,

I traded a lot of options last year and consequently my 1099-B has a lot of transactions in it. The brokerage doesn't seem to have marked if any of them incurred wash sale or not. Reading online seems to give conflicting statements. Is there a definitive guide out there on the treatment? I couldn't find publication 550 for 2018.

I am wondering if I can take losses on all of them or some of them aren't allowable. For example, I have - https://imgur.com/QGsUiIw

In this case, is -1 PUT ABBV 07/27/18 88 considered as substantially identical to -1 PUT ABBV 08/17/18 87.5?
If so, then this makes up a wash sale, correct? Can I add the loss of the former to the cost basis of the latter?

Thanks

I believe for stock options (PUT and CALL) that there are no wash sale rules. If you have losses, they are all allowed.

Thanks!

Glad to help!
