I am a practitioner in Florida, so I do not pretend to be an expert on Virginia Tax.  I rely on the ProSeries software to calculate the Virginia tax correctly once I have entered the correct income and deductions.

In 2019 my client's Resident Virginia Income Tax Return Form 760 showed Virginia Taxable Income of $11,465 and tax of $443.  This is correct, I looked it up in the Virginia Tax Tables. 

However, I found that to be surprising because his 2018 Form 760 showed Taxable Income of $13,481 and tax of Zero.   The tax should have been $545, per the 2018 Virginia Tax Table.

It now appears that ProSeries has calculated the 2018 Virginia Income Tax incorrectly.  Anybody have any thoughts?
