Infamous refers to something that is "well known for being bad!". A classic example would be a (well known) pirate! If the tax you are talking about is bad (I'm pretty sure it is) and well known (also, yes), then "Infamous" is a fine word to use
Notorious is a similar word - well known for something bad
Famous works if it isn't bad, but it usnusually used for people, and I would imagine "the highest threshold" of well-known stuff - so expect people to argue with you: "I haven't heard of X, so it must not be famous!"
Renowned and prominent are fine alternatives to "famous"
My personal favorite is Preeminent- which carries the notion of "#1 best". "My king is the Preeminent leader" - there is NO OTHER leader that can be king
Again, welcome to English, enjoy your stay!
