From setting up review panels to giving assesses time to respond to show cause notices and establishing a parallel verification system, the income tax department has worked out fresh checks and balances in its faceless assessment scheme to make it more robust. Tax officers said that some of the changes were implemented at the start of the financial year itself, when 20 committees were set up to address concerns over high-pitched assessment that some of the taxpayers had raised. “Based on a review by the committees, we will establish whether the assessments are fair or not,” a senior officer said.
