How long does an audit last

Mail audits usually wrap up within three to six months, depending on the issues involved and how quickly and completely you respond to the audit letter

You (or your tax pro) will meet with the IRS agent at an IRS office

The IRS usually starts these audits within a year after you file the return, and wraps them up within three to six months

So, for a person filing on April 15, 2015, the statute would expire on April 15, 2018

In most cases, the IRS will wrap up the audit within a year

Even though the IRS has three years to audit your return, the IRS likes to close audits long before the statute of limitations expires
