I have an underpayment penalty of $108 based on the amount of total tax you entered from your 2017 Kansas return. How could I have avoided this penalty?

[Ashby · Accepted solution]

If your tax payments are greater than 100% of prior year's(2017) tax or 90% of the current year's tax, you will not be subject to an underpayment penalty.

You can only address this by adjusting your paycheck to have more withheld or by paying in quarterly estimated tax payments. 

If you think you need to make estimated tax payments, here's the link to instructions on how to make these payments online to Kansas:
