* As a sports official you are not an employee of NCOA South. Instead you are an independent contractor. Basically your are self-employed and work when you want. Your pay is based on the sport and level that NCOA South has contracted the organization requesting officials. Because you are an independent contractor no taxes are taken out of your checks. However, if you make over $600 in a year we must report that to the IRS.

Officiating is a great way to stay involved in the sport(s) you grew up playing and watching. Also staying involved with youth and helping them become better citizens. Some people even do it for the exercise. Think about it - you'll be paid to be there and have the best seat in the house, and you call your own schedule. What a great way to earn little extra cash. Take a look through this website and it should answer some basic questions about NCOA South and officiating.
