VAT amendment expands valuation and reporting obligations, increases collection rate, and tightens PAN and IEC disclosure requirements. Amendments revise VAT valuation by deeming oil companies' receipts equivalent to retailer prices, raise the collection rate to four percent by substituting prior percentages and removing provisos, assign audit and examination expenses to be determined and paid by the Commissioner (including professional remuneration) with that determination final, and expand dealer registration rules to require declaration of manager name, PAN and IEC with transitional filing obligations and specified penalties for failure to comply.
