Tds wrongly deducted

Instead of telling them that TDS is not applicable on supply, it is better to ask them under which section they have deducted TDS on building supplies. They will automatically get trapped this way..

Appreciate the Quick Revert Sir.

The problem is our invoice stated supply of Installtion Housing.

The client instead of logically reviewing the invoice is stating the mention of the word installation extracts TDS. I argued in the exact same manner as suggested by you but it made things more difficult. He in Turn is now asking me to show him in the books of tax that where is it written that TDS cannot be deducted  or why he should not deduct TDS on the mention of the word installtion without checking the context.

Where do i find this detaill.
Please help me .
