If you say "Just jump through this hoop to get this," no matter how easy you think it is, there will be people you really think need and deserve the reward who won't succeed, and may not even try. Just give everyone what you think some need, and tax it back from those who dont. 
A frustratingly common response to #UBI is why provide it to the rich instead of picking some line like $150k and excluding those above that line? The answer is because that will end up excluding *MANY* of those earning under $12k who can't afford to prove they don't earn $150k.
Stop worrying so much about Bezos getting an extra $12k. It means nothing to him. It means nothing to the economy if he gets it. Focus on ways of effectively increasing his taxes more than $12k so he isn't a net recipient. There are lots of ways to do this.
Pick at least one.
Pick at least one.
And if you think that's inefficient, it isn't even a matter of sending money and then taxing it back later. The rich could opt out of the monthly payments and just accept them as a tax credit at tax time. They already get tax credits by the way. Replace those as part of the deal.
