I am afraid it will only get worse.  I have many clients that have had a string of problems with their GET processing.  These issues have cost them many dollars to correct.  The Hawaii Department of Taxation has many good and experienced professionals that are vey frustrated with the new system and its many challenges.  Those highly experienced staff are counting the days to retirement which will cause the DOTax  to lose the very staff and skills they need to address the issues.  Get ready for bigger problems.
