how long does it take to get your nj state income tax refund
Report Abuse. It may depend on how you filed your state returns. I would guess that the NY was sent electronically with the federal return, and that NJ was sent by mail. If that is the case then you are looking at 6-8 weeks processing time from the day you mailed the tax return out.
