My PA client is migrating to Peoplesoft this year, so we did a quick fix. Controller determined the correct PSD for each employee, and I ran an import into P/R Employee Tax Summary File to correct incorrect jurisdictions from first two pay periods - this included clearing the incorrect jurisdiction.
Each employee's default local tax code is the higher of the residency / employment codes, as required by PA32, so they're okay going forward. Only question is for those employees who work in multiple locations in different tax jurisdictions, but they're not worried about that for now.
