Excise duty on software: All software, except canned software i.e. software that can be sold off the shelf, is ‘exempt’ under notification No. 6/2006-CE dated 1-3-2006.
The above mentions that if a software is sold in a CD DVD etc, like McCafe antivirus, lotus, etc then it is manufacture and it attracts excise duty and also attracts VAT/CST during its sale.
If a software is made as per the customer's specification and not sold in packaged in CDs DVD etc, then it does not come under manufacture so no excise duty on it. But since it is a service, the service tax needs to be paid on it and there is no VAT on services.
