I didn't claim my home mortgage interest & tax last year. Can I claim it this year?

“I didn't claim my home mortgage interest & tax last year. Can I claim it this year?”----> The best way to handle this is to file an amended return for last year, 2011, along with this year's, 2012, return, which will give you the ability to take last years 2011 interest off of last year 2011 and use this year’s 2012 interest against this year2012 as well. You can't mix it up with your 2012 return.
