If so, IRS is proactively going after persons who have not filed income tax returns for multiple years. If you are making $100,000 or more in a given year, the risk is substantially higher. Read this article from the IRS SB/SE Division.
The challenge with nonfilers is that with every year that goes by, they are digging themselves deeper and deeper, which just compounds the problem. Burying your head in the sand, and thinking everything will blow away, is the worst thing you can do when it comes with the IRS. In addition, if you live in a state that require income tax filing, you have state income tax filing obligations as well.
It is important to work with an Enrolled Agent who is experienced in bringing non-filers into compliance.
