State Reciprocity Question

One last question, I believe maybe I am finally understanding this mess! For 2 reciprocating states, if the tax rate amount is higher in the nonresident working state (4.25%) than the resident state (3.23%), the lesser percentage calculated will be the credit received in the home state. What happens to the remainder of the monies taken out in the nonresident state? $780 was taken out but only $595 was credited. What about the remaining $185 that was paid to the non-resident state?
