Do any clubbing provisions exist in case of transfer of income without transfer of asset?
As per section 60​​, if a person transfers inco​me from an asset owned by him without transferring the asset from which the income is generated, then the income from such an asset is taxed in the hands of the transferor (i.e., person transferring the income).   

E.g., Mr. Raj has given a bungalow owned by him on rent.  Annual rent of the bungalow is Rs. 84,000. He transferred entire rental income to his friend Mr. Kumar. However, he did not transfer the bungalow. In this situation, rent of Rs. 84,000 will be taxed in the hands of Mr. Raj.​
