K1 vs. W2

For traditional searchers has anyone filed a K1 for themselves or only for investors? It seems the norm is for searchers to file W2s and be considered employees. My main question is: is there any benefit to the fund or the searchers from filing a K1 vs a W2? If you can pass through losses during the search phase then it seems a K1 would be the way to go, but not sure if that's allowed. I understand to file a K1 you have to be invested in the fund yourself.

Any clarification would be helpful!
