Hey @Mishka,
Welcome to the community. Awesome to hear about your Crossfit Gym - my sister is a coach at a CF Gym and she absolutely loves her job!
Would you mind clarifying your situation a bit more? So, these 10 coaches are currently your official employees (you pay them a set wage and send them W-2s)? Are you trying to switch them over to independent contractors? Are you trying to give them gym memberships instead of pay or just provide the memberships to supplement their existing pay?
The payroll tax question is a complicated one - I'd recommend reaching out to a local tax professional. For the absolute authority on tax rules, the best place to look is "the authority" - the IRS! Here are their published 1099 and W-2 requirements and pay extra attention to the language used.
