I need some insight on taxes. For the first time in 4 or 5 years I went and let a private tax service do my 05 taxes. Well I got a decent return, about 1400 more than I had been getting myself in recent years. Today I got a letter from the IRS saying that I was being audited and need to come up with proof of what was claimed on my taxes. The numbers the IRS had were very different than what I presented to my tax preparer. I didn't look over the forms when I sent them off, this person is used by many people. What should I do? Is it all on me?
