With the widening of tax base there will be a phenomenal growth in the number of service tax assessees. In the ensuing years the department would have to evolve a mechanism where there is management by exception i.e. generally accept all the returns as correct and pick and choose those returns which need detailed scrutiny. In this mechanism a chartered accountant could be of great assistance. Service tax returns and financial statements could be certified by the chartered accountant from the perspective of service tax similar to an audit under section 44AB of the Income-tax Act.
