Must we file again in June on rental income in previous year?

We paid taxes at the end of two quarters of 2011 for rental income obtained from our apartment in Spain.  We also filed a tax form in January, 2012 showing that we had paid what was due and giving the appropriate payment reference numbers. 

My question is this:  do we have to file a 2011 income declaration again before June 20 documenting the same rental income and the tax payments already made last year?  This rental income is our only source of income.  We are non-resident American citizens so have nothing to do with UK taxes.

Very confusing !

A bit confusing.

You don't say where you paid the taxes nor exactly where you are non resident (I assume Spain) or whreyou filed the return in January.

For advice you will need to to be more explicite.

We are non-residents in Spain, residents in the USA.  We filed our Spanish taxes for rental income on Forms 215 after each quarter and Form 210 for the annual return.  I am asking now about refiling IRPF Form 210 again in June.
