Pls help in selecting correct itr form..

Hi,

I want to know which ITR form should be used to file income tax return of my wife. My wife is taking computer training at home. She earns interest in fixed deposit and savings account. Also, she has invested her savings into PPF.

a) Please help in selecting correct ITR form for filing income tax return.

b) Her investment in PPF will not be clubbed with mine, right? I have already exhausted my PPF limit. So, she is investing in PPF assuming she will get separate limit. Please confirm or correct if otherwise.

Regards,

Ashish
