When a final ruling is made, the City of Whitehall will either issue the refund (if that’s the decision) or notify you that you are not eligible to receive the refund due to the court ruling.
Remember that even if you are able to receive a refund of the tax withheld for your workplace city, you will likely owe that tax, or some portion of it to your residence community if that community has a tax. If you have, an outstanding tax debt owed to the City of Whitehall the refund will used to offset this debt.
