Hi,
if any off cycle payments are there for this employee ?
do one thing, delete the table entries in the T7inp3, T7inp4 and again do freshly from the start date from 01.04.2012 to 31.12.9999.
And run the payroll and check it.
Actually system would not deduct the ptax for this employee, but it is considering some thing else.
while running the payroll run with log and please provide the INPTX log screen shot.
Regards,
Praneeth kumar
