We are coaching an All-Star baseball team that operates only with sponsorship and donations. The league that the team plays under let their non-profit EIN number expire. Business want to write off sponsorship/donations to our team, but we can not give them the EIN number since it has expired. The league states that they are in the process of having the EIN re-instated, however this could take months. Can the business still write off sponsorships/donations made to our team and if so, how can they do that?
