Renting for Residential Property

Respected Members,

One of my Client is registered under the GST in the Name of XYZ Infrastructures(propreitorship). He used to provide Construction services. But now he dont have any transaction in XYZ.. but he is getting rental income from Residential Property in his Saving Account. 

So I just want to ask whether we are required to show this Renting Transaction in the GST returns. 

As there is No transaction in the Current account. 

Thanks.
