The ATO has advised that its computer systems will be unavailable from Friday 22 January until Wednesday 27 January 2010 while it implements a new income tax system. In addition, it will need to suspend some processing in the weeks leading up to the implementation. There will also be some processing delays in the weeks following the implementation as the new system gradually returns to full processing levels. The ATO expects these delays may continue during February 2010.
Accordingly, the ATO recommends that agents for business and individual taxpayers expecting a tax refund should lodge their income tax returns as early as possible (no later than 7 December 2009) to reduce the likelihood of any delays.
