Dear Sir,

one of my friend filed Income tax return after due date for FY 2015-16 for his wife who is having commission income near about 20000, but he forgot to claim TDS in his return. Whether CPC at their own process return and refund a TDS which is showing as per 26AS ??

If not how can he claim it?
