I appreciate the responses. This is helpful. I read the instructions for form "1040-ES Estimated Tax for Individuals" and the IRS at various places says "in most cases" making sufficient withholdings (even if untimely) will be sufficient to avoid a tax penalty. Does anyone see a scenario where withholdings would still result in a penalty? I'm unsure due to the use of the langue "in most cases". Again, thanks for the input!
