Sir,
My salary lies in third slab. So my previous account saving (interest on FD) also lies in third slab.
I am already done 80c saving. Query is regarding saving tax on previous years saving rather than income.
M married. Is there a way I can save my savings from third slab by transferring to my wife(housewife) or other way.

Your question addresses tax savings under the Indian income tax system.

Unfortunately, this forum deals exclusively with U.S. taxes, so you likely will not get any answer to your question. Sorry.
