Am not sure, but , as far as money is concerned IFS is the highest paid job in INDIA.But who makes more money IAS has the potential to earn more colored money.
With the implementation of the Sixth Pay Commission, all the Government officials are earning quite well! Actual figures are not known to me but they are earning quite a lot with more thrown in apart from regular salaries!!
I.A.S. is the highest paid job. The cabinet secretary is the senior most IAS officer and his pay is highest. The service chiefs also get same salary. It appears that pay in public sector undertakings is more but these are also headed by I.A.S. officers. The pay scales were fixed by sixth pay commission. The exact pay scale of a post can be seen in sixth pay commission report by using Google search engine.
