If you're doing a lot of convoluted business dealings, I imagine it could be a hassle, but for a regular professional expatriate employee I have not found it complex. I earn a salary; I pay Danish taxes on that salary; I deduct the Danish taxes paid from my U.S. tax obligation as a Foreign Tax Credit; and the net result is negative so I pay no U.S. tax. It would be even easier if I spent less than 35 days/year in the U.S. and qualified for the $95k foreign income exclusion. But even though I don't (I spend ~2 months/yr in the U.S. in an average year), it's still easy enough.
