In my opinion Bangar is the best for IDT.

Vandana Bangar.

VANDANA BANGAR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

SIR AJAY JAIN

Viswanathan Nagarajan

Bangar

Bangar

As per my view no any books are goods available in market because every books have one VVI Drawback i.e.

Excise

Custom

Service Tax

Every book have poor in any one section mainly Custom Import and Export Procedure.

So Try to Devlop concept through 2 to 3 books

bagar will be best for self preparation of idt

vaitheeswaran is good.

DATEY  S THE BEST FOR SELF STUDY...I BOUGHT BANGAR INITIALLY...I HAVENT ATTENDED ANY CLASSES ON IDT...I DINT FIND BANGAR  THE BEST FOR SELF STUDY...OFCOURSE IT S VERY MUCH GOOD FROM EXAM POINT OF VIEW...IF U DONT HAV A STONG GRIP ON CONCEPTS OR IF U HAVNT ATTENDED ANY CLASSES I WOULD SAY DATEY S THE BEST..:)

N.S Govindan, though not much popular, is a very good book.

as per me girish abuja and ravi gupta are best books and taxmann is also one wonderful book
