Mortgage App - confirmation of tax liabilities for rented property

We are in the latter stages of our mortgage application for a new property (owner occupier).
Bank is requesting confirmation of tax liabilities for a rented property I own.

I have copies of my tax returns with rental income for 2009 and 2010 and P21 Balancing Statements for both years.

The return for 2011 has not yet been submitted.
We have a lease agreement for 2012.

Can anyone advise what exactly the bank want?
Is there anything Revenue can provide to demonstate tax compliance?

Any advice greatly appreciated.

Thanks.

What you have sounds like everything a bank would need. But only they can confirm what it is that they want.
