regarding books for ca-final

For income tax theory refer== Girish Ahuja or T.N. Manoharan

For income tax practical’s refer== VK Singhania

For Indirect tax refer == Vandana Bangar

No it is same. Just go ahead. All the Best

any other book if u can suggest for indirect tax

For DT - T.N.Manoharan (for concepts refer V.K.Singhania)

For IDT - Yogendra Bangar

For IDT i recommend Ajay jain sirs text book if you can get it!

I have gone through both Bangar's and Vaitheeswaran's,  and found bangar is more useful for CA Final Preparations.
