Now you have asked "why" should I file. Depending on your circumstances, you may or may not be subject to certain civil fines of $1,000 or more and possibly non-tax negative consequences.
If you are requied to file and intentionally do not file, and the IRS were to come after you, you can be subject to criminal penalties of a fine of no more than $25,000 and a prison term of no more than one year. The IRS likely wouldn't come after you, but theoretically they could.
