<h1>CBEC Extends Form ST-3 Submission Deadline to April 15, 2013, Due to Anticipated Network Congestion on ACES Platform.</h1> The Central Board of Excise Customs (CBEC) has extended the deadline for submitting Form ST-3 for the period from July 1, 2012, to September 30, 2012. Initially set for March 25, 2013, the new deadline is April 15, 2013. This extension is due to the anticipated availability of Form ST-3 on the ACES platform around March 20, 2013, which could lead to network congestion as many assessees attempt to file their returns in a short timeframe, potentially causing delays and inconvenience.
