Whether or not you are charged or have to charge sales tax varies state by state. Here in AZ, nonprofits are exempt from both. I would check in with your state nonprofit commission. If you get a hold of a rep from whatever distributor, they will often work with you to find alternate documentation for "non-traditional" organization structures. We have accounts with both QBP and JBI. Although...we currently cannot order any tires, tubes, cables and a number of other items, and haven't been able to for months. 😬
