Submitted my revenue Form 11 a couple of weeks ago, but now think I might have made a mistake.
In 2010 I overpaid my preliminary tax by about EUR500, so for 2011 I deducted this EUR500 from the amount I paid (i.e. I paid preliminary tax for 2011 minus EUR500).
I think this was wrong and I should have paid the full preliminary tax for 2011 and get a refund from Revenue for the overpayment in 2010.
Do I need to contact them about this or should it be OK (I filed using ROS, so should have until Nov 15th to correct it)?
