The IRS released their Fiscal Year 2009 Enforcement Results last week. Business audits are down while individual audits are up. If your income is over $1 million, you have a 6.42% chance of being audited. If your income is under $200,000, you have a 0.96% chance of being audited. Note that these number include both correspondence audits (where everything is done through the mail) and face-to-face audits. There are 21,059 individuals employed in enforcement by the IRS (revenue agents, revenue officers, and special agents).
