Asking about RA pay

[vern23]

So The school I'm accepted to funds you primarily through RA work and there is a base pay for this, but some profs mentioned that they pay their RA's more than the base. So I've been emailing some potential advisers asking about research opportunities their work if they have openings etc. But I'm wondering is it tacky or bad to ask them if they pay more or how much their RAs make?

Just like any other job, I definitely would not ask about additional salary until the interview, and even then I would prefer to wait until the prof brings up the subject.
