It is really all about accounting. Claiming the hush money was a business expense for retaining lawyers is tax evasion for example. The FEC has disclosure forms about where money is coming from and spent on that are required.
Remember Trump mocking Cruz about his FEC disclosure error when filing for his presidential run? Because Cruz borrowed money against is stock holdings to start up his campaign and didn't properly note its source even though it was his money/personal liability? Trump had a good time with that. Kind of funny Trump is having his issue with that now.
