2.According to the petitioner, he is the proprietor of Tvl.Balans Agency and engaged in the business of dealing home appliances goods and an assessee on the file of the first respondent. For the assessment year 2012-13, the petitioner had filed the returns in time and the respondent passed the deemed assessment order accepting the return. While so, the petitioner was served with a notice dated 07.05.2015 alleging that he had not filed any monthly returns and also not paid the taxes due to the department. Pursuant to the said notice, the petitioner appeared before the respondent and stated that he had filed the online monthly returns in Form-I and paid corresponding taxes. Though the respondent stated that he would consider the same, on 10.08.2016, the petitioner received a notice from the respondent requesting him to pay Rs.7,34,068/- towards tax and Rs.11,01,102/- towards penalty totalling to Rs.18,35,170/-. Since the petitioner did not receive any assessment order for the alleged due, he sent a letter dated 29.09.2016 requesting date of service of alleged assessment order for which, there was no reply. Again on 13.07.2018, the petitioner received a notice demanding to pay Rs.18,35,170/- and the petitioner made an application dated 20.08.2018 under the Right to Information Act, 2005 requesting the date of service of the alleged assessment order. In the meantime, the petitioner received a letter dated 08.08.2018 from his banker that his account was attached by the respondent for the alleged demand of Rs.18,35,170/-. Therefore, the petitioner contends that without giving proper reply to his petition under the RTI Act and without affording any opportunity of personal hearing, the respondent passed the impugned assessment order dated 27.07.2015 in gross violation of principles of natural justice and though the assessment order was passed on 27.07.2015, it was served on the petitioner only on 19.09.2018. According to the petitioner, he has reported a total and taxable turnover of Rs.50,27,260/through online monthly Form-I returns and also paid tax of Rs.7,22,736/- under Section 3(3) of the TNVAT Act which can be verified through the departmental Website. Hence, the petitioner is before this Court.
