This includes the new prélèvement à la source, so in theory I shouldn't owe additional taxes next year.
I personally calculate every mandatory contribution that comes off my gross salary as "taxes" even though many people will disagree. IMHO, it's mandatory, it comes off the top, so it's "taxes"
I wouldn't consider 35% of my gross salary as being overly high, considering the excellent quality of life here. I cannot comment on how this compares to US taxes since I've never lived or worked there.
The taxes/quality of life I experience in Paris is similar to what I had living in Germany.
Given that we have so much vacation here, rent is reasonable, and infrastructure is very good (I can be in Brussels in 2 hours with the TGV) it's unlikely I'll ever move back to Canada.
You mean (insofar as this is a trick), just like the US does?
It certainly depends on your income?
