SAVE ALL OF YOUR RECIEPTS FOR EVERYTHING !
Get yourself a good tax guy (preferably one who has worked for other musicians and will get you solid deductions, and not tempt the IRS with really questionable, iffy claims), and do what he says. This is usually NOT going to be the guy at H+R Block who knocks it out in 10 minutes. You're gonna file the long form, etc. A lot of it will revolve around whether you are self-employed as a full-time musician only, or do you have a day career and play at night as a second job, does your wife work, and on and on.
You'll pay to have this service, but it's WELL worth it. A lot of times, a good CPA, well-known to the local IRS guys, is never questioned by them as they all know the reputation of the guy.
Also, it's been my experience that most musicians can give you REALLY BAD tax advice, so be very careful about that. I'm sure lots of us in the Club can trot out tons of tax horror stories.
Cowboy up, and pay for a good CPA, and you won't be the next one !
