If you owe child support how long does it take for state to take child support out then send you the rest?

It really depends on your state and whether your return is held up for other returns.

In general, if a return is subject to an offset or garnishment, that slows down the overall process by about 1.5 to 2 weeks. If there's an offset of any kind, it does tack on some time.
