We have no idea. It also depends on when you filed, and what state it is. Some states are fairly quick with state refunds, while others such as GA, WV, CO, LA, etc., can take a long time--even several weeks--as they crack down on detecting fraudulent returns.

If you efiled the state return, use the tool below to be sure the state return was successfully efiled and accepted:

FAQ on how long it usually takes to get a refund in your state and how
long to wait before calling them.
