I did a search for tax liability but maybe this situation is just strange enough to not find much helpful. I play in a 20 piece community big band. We play mostly summer gigs, outside festivals or retirement centers. Usually for free, sometimes the place will give us $100-$200 or so. The money all buys new charts and we have never been paid individually for a show. However, a new place is asking about completing W-9 form for the band (on a $200 donation...their words). Any thoughts or suggestions?
