Filing income tax return for fy 2010-2011

Hi, I did not file my returns last year for the income earned during the FY2010-2011. I did not file even by Mar 2012. But my income from salaries and house rent turns out to be less than the TDS paid. So in effect, I would have to get a refund. My question is that can I file the tax return now for the FY2010-2011 without penalty since my TDS is higher than the tax to be paid?
