Wondering if others have run into this situation...have a small 401(k) Plan that terminated. Checks were issued to all participants in 2021. As of 12/31/2021, several people did not cash there checks, so assets remain in the Plan. The Trust therefore does have assets remaining as of 12/31/21. Thoughts on whether 2021 should be the final Form 5500, or doing an additional 5500 for 2022.
