Indiana Department of Revenue guidance supports non-uniform withholding for the purpose of figuring a penalty.
Income Tax Information Bulletin # 3
Dated: December 2023.
Starting on page 3:
‘If withholding as an employee or race team member does not occur evenly over the course of the year, enter the actual withholding during the period during which payments are required. Withholding payments will be treated as occurring on the date of actual withholding (i.e., the date on which you are paid) for purposes of determining any penalty due. You may be asked to provide substantiation of the withholding such as pay statements.’
TurboTax Indiana does not to appear support. The federal underpayment penalty does support non-uniform withholding.
Is this a planned update? When can I expect the update?
