The petitioner is an assessee before the Income Tax Officer, Ward -I(1), Kannur and his Permanent Account Number is ACQPA2788C. For the year ended 31.03.2002, the assessee estimated his income at Rs.5,24,130/- for the period 01.04.2000 to 31.03.2002 and claimed credit for TDS amount of Rs.1,56,655/- effected from the contract receipts. The Assessing Officer granted credit for Rs.43,674/- and declined to give credit for the balance Income Tax Deducted at Source, amounting to `1,12,981/- covered by TDS certificates stating that the amount relates to the current year 2001-02 and TDS deducted for the period 01.04.2001 to 31.03.2002 alone will be given credit. The petitioner filed a rectification petition before the 2nd respondent and the same was rejected by the Assessing Officer stating that there is no mistake. Aggrieved by the said order, the petitioner preferred a revision before the first respondent. The first respondent as per Ext.P6 order dated 14.02.2005 rejected the revision filed under Section 264 of the Income Tax Act (for short 'the Act'). It is the said order which is assailed in this petition.
