The Cabinet on Wednesday cleared an ambitious Rs 4,242 crore project for e-filling and centralised processing of income tax return, which will allow taxpayers to get a refund in one day through a pre-filled tax return form, the Times of India reported. Currently, the average time taken for return processing and giving a refund is 63 days, which will get reduced to one day, the daily quoted railway minister Piyush Goyal as saying.
