Remember Bush41 used an executive order to change the witholding tables..that was inplimented pretty quickly..this would be pretty much the same accounting procedure. You are correct, it can be done fairly quickly.
Yeah, actually I was working on financial software when he did the change in the tables. It was a bit of a pain in the ass but it wasn’t that tough, the biggest pain was to make sure all the clients had the new dll in place on time, the actual implementation wasn’t that tough.
