Tax collection at source expanded to minerals and cash bullion/jewellery sales; collectors must remit tax at point of sale. The amendment adds minerals (coal, lignite, iron ore) to the tax collection Table and inserts a new provision requiring sellers receiving cash for bullion or jewellery to collect tax at source at the time of receipt where consideration exceeds the statutory threshold. Definitions of 'buyer', 'jewellery' and 'accountant' are inserted or clarified. A proviso exempts collectors (other than those under the bullion/jewellery rule) from being assessee in default if the buyer files a return, declares the amount, pays tax and furnishes an accountant's certificate; interest rules are adjusted accordingly.
