On the campaign trail, President Trump frequently said America’s tax rate was the highest in the world — and for this group of Americans he wasn’t far off the mark.

The income-tax rate for childless single people in America is the eighth highest out of the Organization for Economic Cooperation and Development’s (OECD) 35 member countries at 16.9%, the Paris-based organization found. While that’s less than half what the average single person pays in Denmark (35.9%), it is above the OECD average (13.4%). Other countries where single people pay more than Americans include Iceland and Australia.
