I take payment for cantorial services, technically. I don’t accept extra payment for teaching.
However, there’s a teshuva of the Rashbatz that allows scholars functioning as the communal rav to accept payment; he reasons that ince the Kohen Gadol receives material support from the community, how much more so should a Torah scholar be entitled to such support; after all, he is equally performing a service for the community.
The Rema also says that a person important to the community may accept money from it, without violating the prohibition against benefiting from the Torah, for he is honoring the Torah, not using it.
Your typical Zevi Chaim learning in kollel or beis medresh doesn’t fulfill either of these criteria for getting paid. The Rema clearly has someone chashuv in mind, not a typical guy learning.
