Where property taxes are shown on the HUD-1 is an old question that has been much debated.
Property taxes that are apportioned at closing are generally disclosed on page in the 100/400 series or the 200/500 series. Property taxes that are escrowed for the next year go in the 1000 series on page 2. Past due property taxes do not appear on the form since they are not a settlement charge.
The treatment of past due taxes changes in August 2015 since everything that impacts cash due at closing has to appear on the form.
