Most audits on individuals are random (and its a very low percentage)
and the IRS doesn't make it publicly known what criteria they use to
determine audits.
If you filed your tax return with TurboTax, you already have the TurboTax Audit Support Guarantee. TurboTax also offers Audit Defense, an optional add-on product that must be purchased when you file your taxes. You can't add Audit Defense after filing your return.
Our TurboTax Audit Support Guarantee gives you
free audit guidance from a trained tax professional to help you understand your IRS notice and answer all your audit-related questions.
Audit
Support guarantee covers all 2014, 2015, and 2016 federal and state
returns prepared in TurboTax Basic, Deluxe, Premier, Home &
Business, Self-Employed, Free Edition, and Freedom Edition.
