On the S Corporation form CD-429 PTE (Taxed S Corporation Estimated Income Tax) the last digit of the zip code does not print. There appears to be room for the digit; however, it does not print. In my case the digit is a zero so I don't know if this makes a difference. If the print field needs to be shifted to the left to allow for the digit, there appears to be room to do so. This is a program design issue.
