The Income Tax Department is embarking on an exercise to collect the complete tax profile of individual assessees in the country as part of measures to end tax evasion and money laundering.

"The finance minister has given the go-ahead for integrated 360-degree mapping of individual tax payers by utilising data collected from various sources like annual information returns (AIRs) from banks, credit cards, mutual funds, stock market and property registrars," a senior finance ministry official said.

On Tuesday, Finance Minister P Chidambaram had said that in the meeting of chief income tax commissioners, decision has been taken for integrated tax mapping. He, however, declined to give details about the project.

Sources said after a successful pilot project on integrated tax profiling in Delhi, the I-T department also has plans to prepare a huge data bank that would have all sorts of information on potential tax evading individuals and corporate houses.

The government has so far gathered information about Rs 60,00,000 crore (Rs 60,000 billion) investment by tax payers through AIRs. Under the tax mapping, the department plans to explore cases involving large scale tax evasion.

The sources said the Financial Intelligence Unit (FIU) under the ministry will also provide information about potential tax evaders, as it collects and analyses information about financial transactions through banks and other financial institutions.

The sources said tax officials are preparing a list of targetted people, whose expenditure through credit and debit cards, property registration, hotel expenses and travel expenditure is immediately reflected against his name at Central Information Bureau, set up for this purpose.

The government has already set up 15 CIBs offices across the country and a move is on to expand it to cover all state capitals.

At the national conference of chief income tax commissioners, which concluded in Delhi on Wednesday, the officials have recommended a '360-degree profiling' of potential tax and revenue offenders, the sources said.

They said the 360-degree profiling includes linking an individual with all his possible fronts and contacts and thus preparing a complete dossier.

The government has equipped the I-T Department with state-of-the-art phone surveillance system that can track calls of a target even if he uses a phone that cannot even remotely be traced to him.

In the large tax units (LTUs), the finance ministry is already collating information about excise, customs, service and income tax paid by corporates for better tax assessment.

Once the information is collected against the PAN number, the comprehensive dossier is then sent to the assessing officer to match it with I-T returns that the person has filed.

The accounts of those who have not declared total expenditure in their returns, will automatically get notices for scrutiny, the sources said.
