So you want the FedGov to do it.
I remind you Lois Lerner came from the IRS. IRS part of the Treasure is chock full of radicalized TEU (Treasure Employee Union) members. Even after its been neutered, particularly neutered by something very unlikely to happen. (If I remember correctly FairTax is the consumption tax proposal. Something I support in theory! A lot of details need to be worked out!)
When it comes to politics there are no neutral parties not now, never has been! My point is acknowledge that, keep it simple. Make policeable by those who have an interest in the outcome. Place political party threshold maybe at 5% participation in last election (Maybe not even have a participation threshold) if people want to cheat they will cheat!
Not necessarily, that was just an idea to put SOME of the currently useless to work. I don't like the idea of creating a new agency when so many need to be eliminated. Maybe we should contract it out to private businesses.
...if people want to cheat they will cheat!
So, shall we give up on the wall, because there will be attempts to tunnel under it? Why lock your doors, as a determined criminal will just break the lock?
