Is there a penalty for the underpayment of taxes?

In the case of an individual, if the tax liability after certain credits and after subtracting federal withholding is more than $1,000, then a penalty for the underpayment of taxes is applicable. Penalties are figured separately for each of the four payment periods. Form 2210 is used to calculate the underpayment penalty. There are exceptions and waivers available that can be used to minimize or alleviate the penalty. Speak to your local CPA about the exceptions and waivers to minimize your penalty due. There are similar estimate payment requirements and penalty ramifications for corporations.
