If things are going so well, why can't the state "properly track" returns that are filed more frequently than required?  According to Tax Announcement 2017-04 (TA), they're going to switch people who choose to file quarterly but are required to file semi-annually to file monthly.  

Not only that, but I was told no notices will be sent to these taxpayers.  The tax practitioner specialist I contacted was not aware of any effort to educate taxpayers regarding this change in filing requirements.

Hopefully with the added attention on the modernization project, someone will realize this is not a fair way to treat taxpayers and at least have some information in the media about the switch.  The TA is here - http://files.hawaii.gov/tax/news/announce/ann17-04.pdf.
