Great confusion please help

excess of interest over 9.5% is taxable.

it is given in V.K.SINGHANIA

Interest credited to RPF:

Exempt from tax if rate of interest does not exceed notified rate of interest

(i.e., 9.5 % before september 1,2010 and 8.5 % with effect from September 1 , 2010 )

excess of interest over notified rate of interest is taxable

45th edition 

2011-12
 

in V.K.singhania it is given 8.5%

44th edition A.Y. 2011-2012

yes. it depends on the dates as was mentioned earlier

i think it is 9.5%                                                                     

i think for nov 2011 attampt we should adopt 8.5% , every body pls share their own views on this issue. bcoz realy it is confusing

for nov 2011 , wich rates we need to follow is it  2011-12 assesmnet year rates?

ya this is of great confusion but i think it is 8.5% because in latest editions questions are solved with 8.5%

any other views please post
