Are you self employed of PAYE?
Are you a member of a occ pension?
If self employed you can make a contribution before the 31st October and set it off against your 2013 tax bill.
If you are a member of a Occ Scheme you can make a contribution before 31 October however you must state that the contribution relates to the 2013 tax year.
If you have a personal pension or PRSA you are too late to make a payment relating to 2013. You cannot retrospective payment.
It's amazing that Revenue are giving the wrong information. I asked the lady about this and she consulted three of her colleagues who said I couldn't do it.
