Question: How is a non-profit organization different from a regular business or corporation?

I'm interested in volunteering or even interning in some non-profit organizations located in my city. I was just wondering: what makes an organization a nonprofit one? What are the defining characteristics? How is it different from a corporate entity? Also: in a communist government, can the government "take over" nonprofit organizations like it does to small businesses? Is it true that nonprofit companies are exempt from corporate taxes?

Thanks a lot in advance!

Answer:

I run a 501c3 non-profit in Oklahoma. Heres the difference:
A non profit has to be an organization made up of a board of atleast 5 members. It is tax-free but this is where they get you..even thou the business is expemt, someone still takes home 49% of the revenue, 10-99 forms...which you pay a percentage of that at tax time.
A corporate entity, is mainly formed from one particular person, a non profit is formed by atleast 5.
And no, the government cannot take over your business, however your board members can! They can vote you out in a heart beat, so make sure you get people you trust. Once you are voted out,then the vice president (who you appointed) will take over and there isnt anthing you can do. Hope this helps some.
