An assessee has regularly filing his ITR. In Assessment year 2010-11 due to some some miscommunication ITR has got skipped from filing althought TDS has also been deducted and advance tax has also been paid for the said year. Aferwards he is filinging his returns regularly. Now in assessment of 2011-12 ITO has charged income tax on the difference between the closing capital of AY 2009-10 and opening capital of AY 2011-12.
Is there any provision/ case law that can guide.
