Tax Deduction at Source updated: contractors' payments now subject to TDS on credit or payment, with advertising treated separately. Amendment to section 194C(1) effective 1 June 2007 requires persons paying contractors for carrying out work, including supply of labour, under contracts with specified categories of payees to deduct tax at source at the time of credit or payment, whichever is earlier. The amendment lists covered payees, links applicability for individuals and HUFs to turnover thresholds under section 44AB, prescribes differentiated withholding rates for advertising and other payments, and exempts individuals and HUFs from deduction where payments are exclusively for personal purposes.
