Return of security: timelines and conditions for retention, objection and release under VAT safe-keeping rules. Securities furnished under the VAT law (post office passbooks, bank deposit receipts, bonds, promissory notes, stock certificates) shall be kept in safe custody by the Commissioner or his nominee and retained until the Commissioner orders otherwise. A person who ceases to be a dealer or whose activities no longer require security may apply for return, release or discharge in the prescribed form; objections lie if the Commissioner fails to return the security within the prescribed period. Return or release must comply with the terms of the security and be accompanied by a signed, witnessed acknowledgment detailing the security.
