Tribunal held that notice under section 143(2) was required to be given to an assessee by the Assessing Officer for scrutinising its return. This was an opportunity to an assessee to submit what the assessee wants to submit in support of the return he had submitted. On receipt of such notice, the assessee realised the mistake that his tax consultant had not included the income with respect two bank accounts. The assessee had submitted details of the bank accounts to the tax consultants and its income was to be computed under section 44AD . Somehow the details from two banks accounts were not considered by the tax consultant while filing the return. Therefore, the moment it came to know to the notice of the assessee, he immediately filed a revised statement and paid taxes. He did not dispute inclusion of the income embedded in those accounts. Similarly, he had included certain minor income in shape of dividend income and interest income. No doubt the assessee should have been more vigilant while filing return but he was running a proprietary concern and had given all the details to his tax consultant. Under some human error, the proceeds from retail sale of chemicals deposited in two accounts remained to be accounted for the purpose of computation of turnover for estimating the profits under section 44AD . Omission by the assessee was neither deliberate nor contumacious in conscious disregard to his obligation. The assessee had immediately filed a revised statement and paid taxes. It was a bona fide mistake not warranting penalty.( AY.2014-15)
