Most people without businesses don't need to worry about audits. IRS, of course, still audit a small percentage of the most simple and honest-looking returns. But that is mostly for how factories spot check products to ensure quality, not because they suspect you did something wrong.

On other hand, if you are audited, it is not a big deal as long as you were not intentionally defrauding IRS. My boss used to get audited almost every year for his business. IRS would ask for receipts, and once he provided those, it was end of story.
