You create a variable 'value' in action performed... nothing tells class CalcTax what that value is. Study my fixed snippet and you will see what went wrong. I have now passed 'value' to your calculate( double value ) method in class CalcTax.
  public void actionPerformed(ActionEvent event) {
    CalcTax myCalcTax = new CalcTax();
    double value = Double.parseDouble(propVal.getText());
    myCalcTax.calculate( value );
    taxBill.setText("Property tax is $" + myCalcTax.getTax());
class CalcTax {
  final static double tax = 0.325;
  static double pTax;
  public static void calculate( double value ) {
    pTax = .325 * value;
  public static double getTax() {
    return pTax;
}
