For the 100 hourly the USA has a buffer of 10 hours but only to transfer an aircraft for maintenance. The thing is though that these little bits of extra time cant be accumulated. ie if you go over by say 5 hours then the next hundred hourly is due in 95 hours. It gives a little bit of flexibility without the commercial pressure to constantly go over. It is also a little bit arbitrary but aircraft don't seem to be falling out of the sky from maintenance being a few hours either way....
I am not sure if they have a similar thing for annual inspections, I haven't dug out the regulations to check.
