Child support can be modified based upon a change in income of the parties. This can be done every two years.
There are other bases upon which the parties can seek to modify child support, such as economic hardship, a change in the age category of the child(ren), a substantial change in circumstances, etc. The timeframe after which you can modify under these circumstances varies.
