The other advantage is legal liability. If you are a cooperation (aka a company) and do things as a company you are personally legally responsaible for the liability.
If a church is NOT incorporated and someone comes in and slips and breaks a leg, every member who goes there is legally liable for the lawsuit. Let's say you have a 100 family church and someone win a judgement for 10,000,000 every family is legally liable for 100,000.
Now if a church in incorporated and someone falls and gets a $10M judgement then it is the church that is on the hook for the money.
This is the same for a disc golf group. The first action should be to incorporate and get a legal protection.
As far as a 501c3 I really doubt that most will need to file as such. If you are a 501c3 then you can accept tax deductiable donations.
Got to love Uncle Sam trying to bend over the 501c3's. Sometimes I think that some churches should be taxed as some Pastors become millionaires...we have one here in Alaska. He lives just as good as the C-positions of big corporations around here...I think that is BS.
Sorry, off topic...I’ll have to follow up with my organization to make sure that we're in compliance.
