Community development services are related to the provision of financial services. Community development loans and qualified investments do not have that provision. Therefore, if your employees were volunteering their time to collect or organize food for the food bank, I would agree that those services do not qualify. Your employees are not using their financial expertise to serve. However, a donation to the food bank should give you credit under the investment test. Similarly, a loan to the food bank might count as a community development loan, as long as it's not already reported as a small business loan.
Don't make me say, "I told you so!" Sincerely, your friendly Compliance Officer.
