Collection of Tax at Source requires sellers meeting turnover criteria to collect a nominal rate on high value goods sales. Sellers whose preceding year turnover exceeds the specified limit must collect Collection of Tax at Source under Section 206C(1H) at a small percentage on sale consideration exceeding the prescribed threshold, excluding exports and goods covered by certain other sub sections. The obligation does not apply where the buyer deducts tax under another provision. Absence of buyer PAN/Aadhaar invokes the altered rate prescribed in section 206CC(1)(ii). Definitions of buyer and seller contain specified exclusions and turnover based tests, and notifications/circulars modify buyer treatment and confirm interplay with other TDS/TCS provisions; the Finance Act, 2025 affects the provision's applicability from a later date.
