Today, Revenue announced an extension to the return filing and tax payment date for self-assessment customers using the Revenue On-Line Service (ROS). For customers who file the 2009 Form 11 return and make the appropriate payment through ROS for: * Preliminary Tax for 2010, * Income Tax balance due for 2009, the due date is extended to Tuesday, 16th November 2010. To qualify for the extension, customers must both pay and file through ROS. Where only one of these actions is completed through ROS, the extension does not apply. Customers who pay or file by means other than ROS are required to submit both payment and return on or before 31st October 2010.
