New Delhi: The tax department under the finance ministry is planning for a mechanism to set a monetary limit for issuing goods and services tax or GST demand notices to ensure that notices are not issued on flimsy grounds. The ministry is expected to issue an instruction soon to the field formations in this regard, a senior official said on Tuesday. “We will ensure some sort of mentoring by senior officers so that notices are not issued on flimsy grounds,” Priya said. The official also said that once a demand is raised, field offices must ensure ‘fair adjudication. “We have sent letters to all the associations and field formations to interact with the taxpayers to see where in the existing GSTR-3B framework amendments are needed,” he said.
