Entry No. 11 of 12/2017-CT(R) reads as under
"Services by way of pure labor contracts of construction, erection, commissioning, or installation of original works pertaining to a single residential unit otherwise than as a part of a residential complex."
whereas (zze) “single residential unit” means a self-contained residential unit which is designed for use, wholly or principally, for residential purposes for one family;
As per my opinion, there is single housing project having single RERA Registration wherein there are multiple single residential units which cannot be treated as self-contained residential unit and hence, exemption cannot be availed rather concessional rate of 12% may be available to the contractor.
