The IRS is weighing a box on the 1040 asking if you are not a US citizen or hold dual citizenship. But this box will not change what anyone owes. US citizens already report worldwide income no matter where they live, and non-citizens owe based on where they reside and where their income comes from. The box doesn't change a single tax bill. It's even stranger to ask who is a dual citizen because as long as you are a US citizen (irrespective of other citizenships) you are taxed the same as all other US citizens. There is no special tax treatment for dual citizens. Naturalized citizens disclosed their other citizenship when they applied to become US citizens. Those born abroad to a US parent documented theirs through a CRBA with the State Department. The government already has all of this on file. So all this new rule does is put an asterisk on millions of tax returns for further review by the government. I work with many internationals who live and build here and file a 1040 every year. Most would not like being put in a special "ready for further review" box and may start looking to other countries for their businesses and investments. I'm struggling to see the benefits to this policy.

@adrianpandev It's probably so that the IRS could form an estimate of how many people might look at voluntary renunciation of US citizenship. In March, after years of campaigning, the punitive 'exit fee' of $2.350 was cut to $450. pbs.org/newshour/polit…
