Just pay the damn taxes.
Anyway, the Alliance now controls the Star Domain Government, which can retain 30% of the Imperial Tax. Under such circumstances, the Alliance hasn't invested a penny in the planet, so taking 30% of the tax revenue is nothing unacceptable.
If things are done too poorly, leading to the inhabitants of the planet being unable to survive, then the Alliance would have an excuse to intervene, following the Imperial rules to forcibly evacuate and start anew, without getting entangled in local interest groups. By confiscating all private property on the planet and establishing an Alliance-style government while maintaining military control.
If things go well... wouldn't everyone be happy? The tax rate could be raised, and once things reach a certain level, the Alliance could certainly think of other ways to pluck the ripe fruit.
However, this kind of situation is probably one in a hundred planets.
