We are pvt ltd company . I have filed TDS return for Q2 of F.Y.2014-15 for 26Q. In this return I have entered wrong PAN of one deductee (entire PAN is wrong) for which I have deduted tds on interest paid @ 10%. For which IT has demanded short deducttion penalty unser Applicable Tax Rate As Per Section 206AA. Even after coorection return filled IT is demanding penalty. Should I have to pay penalty (Rs.2100) because entire PAN is wrong? Or can my penalty will be waive off if I write a letter to IT department.
