This current rule only applies to high earners (those earning over $100,000 in 2016), who have to pay tax on anything over that amount to both the host country and the US.

Republicans Overseas, a group of party donors, has been lobbying congress for years, and submitted a letter to the House’s committee.

The FT reported on Wednesday 25 October that Kevin Brady, the Republican head of the House ways and means committee, said that they were considering the measure as part of a tax reform bill.

The House of Representatives ways and means committee and the Senate finance committee are responsible for the drafting of the tax bill.

Brady told the FT that congress was taking “seriously” the call from a citizen-based income tax system to a residence-based system. The White House budget office director, Mick Mulvaney also told the FT that he would support the change.
