(2)…………………..
----
(5) Notwithstanding anything contained in sub-section (1) of section 16 and sub-section(1) of
section 18, input tax credit shall not be available in respect of the following, namely:—
…….
……..
(c) works contract services when supplied for construction of an immovable property
(other than plant and machinery) except where it is an input service for further supply of
works contract service;
(d) goods or services or both received by a taxable person for construction of an
immovable property (other than plant or machinery) on his own account including when such
goods or services or both are used in the course or furtherance of business.
Explanation: –For the purposes of clauses (c) and (d), the expression “construction” includes
re-construction, renovation, additions or alterations or repairs, to the extent of capitalisation, to the said immovable property;
Therefore, Lift is not Plant and Machinery and therefore GST Input is not permissible
