States can just collect income taxes and withhold them until FEMA pays up. Most states pay more to the feds than they get in return. The rest could get more revenue if they threw off regulatory shackles.
As it is, many states come up with reasons to get FEMA money because they pay into it and never have natural disasters.

Or the state treasurer gets arrested by the Secret Service.
Legally, the states can’t seize federal tax revenue anymore than you can not pay income taxes.
