Security requirements for VAT registration and release of premises or goods establish document-based reductions and thresholds for furnishing security. Registration applicants must furnish security up to one lakh rupees, reducible by specified document-linked amounts subject to a fifty thousand rupee maximum reduction. Separate security obligations apply for de-sealing or release of premises calculated against recent gross turnover or a higher fixed threshold, for release of seized goods based on twice the tax payable if sold locally, and for refunds where the Commissioner may require security up to the refund amount.
