All Virginia employers are now required to file 2013 & later W-2 reports electronically with the Virginia Department of Taxation (along with other withholding & sales tax reports) .
If you handle payroll "in-house," you need to make sure you're prepared to upload your VA-6 and W-2 reports at year end, either through your payroll software or by using the the VA Tax Web Upload or Eforms method. And if you use an outside service, make sure that firm is prepared to efile with Virginia.
E-filing and e-payment guidelines are at the VA Tax website at

Please call or email me if you have any questions about these or other matters.
