A Senior citizen & US green card holder under treatment for cancer in US couldn't file IT return since A/Y 2009-2010. She has only other sources income in India (Bank interest on deposits) which is below Rs 2.5 Lac. Bank deducted 10%. Can she file return now for all these years and get back refund of 10% without penalty for delayed submission? What would be the penalty in case the other sources income exceeds than the exemption limit in any one year?
