You’ve filed all of your tax returns, and because of your level of income you find yourself in the class of taxpayers whose return is more likely to trigger an IRS audit. So you wonder, how long does the IRS now have to audit you?

Due to disclosure requirements, the IRS makes contact with a taxpayer selected for an audit by telephone or mail only.  When returns are filed, they are compared against norms for similar returns. These norms are developed from audits of a statistically valid random sample of returns, selected as part of the National Research Program conducted by the IRS to update return selection information.
