After you file

Your return is what you file.  Your *refund* might be held for a verity of reasons, checking for fraud or ID fraud is one.  That is not an audit.  The initial tax return is very seldom  set aside for an actual audit, although the IRS does do random compliance audits selected totally at random.  The chanced of that are very low.

Errors, missing income, and other IRS checks usually just result in a letter (CP2000) from the IRS which is not an audit.  It would be very unusual for an actual audit of a tax return to take place sooner than a year after the filing date.

In no event would an audit take place before the due date of the tax return (April 18, 2017) since the return is not official or final until then and can be changed by the tax payer.
