Although a non-profit organization is an unlikely source of personal income. However, there are a few ways you can earn money running these organizations.
All the non-profit organizations made to fulfill charitable, educational, or scientific purposes are registered with Internal Revenue Service, which means they do not need to pay tax for that specific amount. This means if they earn more than they spend, the excess money stays within the organization.
These organizations can also apply for funds and grants to run the company. They can rent their property, run business ventures, make investments, or sell donated merchandise to make money.
