Contractor business code in income tax

For a contractor, the business code in the Indian income tax system depends on the specific type of construction or service being provided. The codes fall under the “CONSTRUCTION” category, which includes several sub-sectors. 
Here are the relevant codes: 
  • 06001: For site preparation work.
  • 06002: For building complete constructions or parts, applicable to civil contractors.
  • 06003: For building installation activities, such as electrical, plumbing, and other fittings.
  • 06004: For building completion activities, which includes plastering, painting, and tiling.
  • 06005 :Construction and maintenance of roads, rails, bridges, tunnels, ports, harbour, runways etc.
  • 06006 :Construction and maintenance of power plants
  • 06007 :Construction and maintenance of industrial plants
  • 06008 Construction and maintenance of power transmission and telecommunication lines
  • 06009 :Construction of water ways and water reservoirs
  •  06010: For other construction activities not specified elsewhere (“n.e.c.”). This may be the right option if your work does not fit into the more specific categories
