I'm not sure what the comparison between UK (where I am) and US taxes is, but I found the process here very easy. I load up an online form, I fill in the data and click submit, they tell me how much I owe and I pay. Very easy, the hardest part is saying goodbye to all that money.
The comparison, sadly, is totally different. The UK system is relatively simple (I never even had to do a tax return when living there), the US system is a byzantine labyrinth.
