13. Not bothering to file at all
The most likely action that will draw the attention and ire of the IRS is to not file any tax returns at all. After all, it’s the bare minimum requirement of any tax year.
Even worse, for both your sanity and your pocket, is if you happen to owe the IRS but fail to pay up. Not only will you incur penalties for late payment, you will be hit with a double whammy as they with also penalize you for filing late.
Even if you owe nothing or have no income, file anyway.
