If anyone happens to be preparing payroll reports with NC withholding, there's a new wrinkle this year. For the past 2-3 years, NC has been requiring that the Copy 1 of W-2 (accompanied by the NC3) be filed electronically by Jan 31. However, around mid-December they have been granting waivers from the electronic filing requirement because their portal wasn't ready for filers of small quantities of W-2. As of Dec 24, 2018, there has been no waiver granted for 2018 forms. This means that there's a $200 penalty for filing paper copies of NC3/W2 even if you only file a small number of the forms.
The NCDOR is still working on a way to manually enter the W2/NC3 information using a specially-designed spreadsheet. The 2018 spreadsheet was available for trial use until a couple of weeks ago, when they took it down for "maintenance", stating that now it won't be available until Jan 2, 2019. Assuming they get it back up and going, this will mean that employer data and individual NC withholding data will need to be entered manually if the filer uses the spreadsheet (unless of course they grant another waiver in the upcoming week).
