The Income Tax Department will soon send notices to individuals who have not filed income tax returns (ITRs). The notices will be sent to even those whose income tax has been deducted at source, The Economic Times reported on Sunday. Central Board of Direct Taxes (CBDT) chairman Nitin Gupta said that the department will be sending notices to only those taxpayers for which it had definitive information. He said the department's focus was on improving taxpayer services, from bringing down the period of refund to updated returns or solving a large tax dispute.
