Industrial installation services, including equipment installation and plant erection, are treated as works contract or industrial construction services under GST. Earlier, different ways of splitting machinery supply and installation sometimes produced different effective tax outcomes for similar projects, which complicated costing and tax planning for both contractors and industrial clients.
After the September 2025 rationalisation, most industrial installation services under SAC 995468 generally fall in the 18% slab with input tax credit. This standard rate applies where equipment and machinery are installed as part of a works contract, unless a specific notification grants concessional treatment for a particular strategic or government supported scheme.
The table below gives the latest GST rate for services under SAC code 995468.
