Declaration of Investments post receiving Form 16

Hi,

In my company, I had declared my investments for current year in the month of January. However, there was a revision of salary in the month of February as a result of which my tax liability has increased. My question is if I make more tax saving investments/donations, can I show them in ITR, though, the same would not be reflected in Form 16, especially since I file my ITR online and there is no provision for submission of documents.

Thanks for your reply.

Regards,

Vineet
