What is the tax treatment of composite rent when the composite rent pertains to letting of building along with other assets?
Composite rent includes rent of building and rent towards other assets or facilities. The tax treatment of composite rent is as follows:-
(a) In a case where letting out of building and letting out of other assets are inseparable (i.e., both the lettings are composite and not separable, e.g., letting of equipped theatre), entire rent (i.e. composite rent) will be charged to tax under the head “Profits and gains of business and profession” or “Income from other sources”, as the case may be. Nothing is charged to tax under the head “Income from house property”.. 
(b)  In a case where, letting out of building and letting out of other assets are separable (i.e., both the lettings are separable, e.g., letting out of refrigerator along with residential bungalow), rent of building will be charged to tax under the head “Income from house property” and rent of other assets will be charged to tax under the head “Profits and gains of business and profession” or “Income from other sources”, as the case may be. This rule is applicable, even if the owner receives composite rent for both the lettings. In other words, in such a case, the composite rent is to be allocated for letting out of building and for letting of other assets.
