IRS help

[boiseball]

Okay guys, I need tax advise. In as much detail as you feel comfortable giving, how do you handle your referee income and deductions. Specifically, what expenses can you claim and how do you calculate them and keep track of them efficiently and accurately. I have not been doing a good enough job with this, and my day job has finally gotten to the point where I care a whole lot more. I appreciate your help with this. All tricks of the trade are welcome.
