The report by the National Institute of Public Finance and Policy (NIPFP) titled 'Analytical Model for Widening of Taxpayers Base' also suggested tax policy incentives should only be given to those who comply with the tax laws like filing of returns.
Arguing for refraining from increasing the exemption threshold too frequently, the report said: "...While every government has the right to decide on the exemption threshold, increases in the exemption threshold tends to erode the tax base in terms of number of taxpayers significantly."
The report said India continues to be a cash-based economy which undermines compliance with tax laws and made a case for incentivising the move away from cash to other financial instruments.
NIPFP report further said that it has been argued that some of the success from the effort to collect information is defeated by the option of filing forms 60 and 61 (filled by those who do not have either a PAN or GIR).

Noting that tax departments tend to face a lot of bad publicity for their efforts to bring in the evading taxpayer, the report said it would be useful to address this issue by periodically putting out information on the extent of interface of the tax department with the average tax payer.
The report also said it is necessary to increase the ambit of third party reporting in India also.
"Considering the fact that CIB (Central Information Branch) has not been effective in increasing the tax base, there is no point in continuing with this experiment.
