Clubbing of income - do we need to file itr with 0 income

Hello all, one doubt with respect to clubbing of income...

<<Sorry if this was asked earlier, please message me the link. From my search, could not get... so posting..>>

Husband invests in MF in the name of wife, and he clubs the interest income earned from wife in his ITR with mention of amounts in schedule SPI. Wife does not have any other source of income. In this case, should wife also file an ITR with zero income? Or can she ignore?

Last year, IT dept. sent a mail to wife asking to file return due to investments in MFs exceeding 2 Lakh. For that, we have given a response saying there is no taxable income and interest income is clubbed in husband's name with mention of PAN, and further there was no other mail.

Just want to confirm from experts here if we can skip filing ITR for wife...

Thanks all in advance...
