Large Taxpayers unit

As you drive down the Ring road (thats what it is called, it is mostly a regular vehicle path, no highway) in Bangalore towards the Mysore road, on your left, appears a building that has the name, "Large Taxpayers unit" on a board in front. Oh yes, it is the Income Tax office that has this site, presumably for those pay "a large amount of taxes."

Now, how about a building for the "Never paid income tax" unit or one for "Never asked to pay income tax" unit?
