Why would you ever turn down a raise in salary?
Jurisdictions will vary but I can imagine calculation methods for child support where the raise could become significant in the present with long future ramifications as well, even if the job is temporary or the parent wanted to step away from working full-time to attend school. The timing of the raise might coincide with disclosure of income to an ex-spouse or to the court related and it might be preferable to postpone the increase. Of course the court would probably frown on declining the raise for only these reasons. If it found out it might impute the higher income anyway. And I'm not suggesting that people dodge responsibility for their kids. We've all seen those cases where child support is not particularly equitable between the two parties and/or the kids do not necessarily benefit by the transfer of money. I wouldn't blame a parent for thoughtfully and unselfishly considering this type of second-order effect and consulting an attorney as with so many other financial implications of divorce. Regardless of personal moral objections it's certainly an answer to the question in technical terms that somebody somewhere has taken into account.
