Any non US gme holders who signed one of these w-8ben forms in 2021 will need to renew, otherwise your shares can be sold by your broker.

My broker notified me that I had a few months left to renew the form. Double check yours!

The form lasts about 3 years, so very easy to forget about :)

Edit - for those asking;

On CS > profile > tax details and you can clearly see a "status" of your w8ben form expiry. Then a "certify tax status"

Hope this helps, mine runs out real soon

Don't rush and REMEMBER YOUR BIRTHDATE is US style, month first!! Also FTIN number is your national insurance number if you're UK. CS will email you to confirm

Edit 4 WISE ACCOUNT ISSUES BakedEmu found a solution to the problems some have. You have to make sure there's a uk (or supported nation) bank account for the money to goto! Problem should resolve within a few days. From another user - if they wish to continue using WISE USD account then they can submit W8BEN by post.
