Mr. Jayanth
The transaction mentioned by you is in nature of obtaining licence on Annual basis. Is this software available on the shelf or is it something which is exclusively customised for your requirement?
If the software is an on the shelf product and the vendor charges only VAT, I do not see a necessity for you to deduct Tax.
However, if the product is customised by the vendor to suit your requirement and charges annual licence fee, it becomes royalty and is subject to TDS.
