The finance ministry will launch helpdesks for small taxpayers from July to bring in more people in the tax net and mop up over Rs 273,000 crore (Rs 2,730 billion) in revenues this fiscal.

For large taxpayers, especially those for excise and customs duties, the finance ministry is expected to allow corporates to pay the duties from one commissionerate and devise a system to assess the revenue on a monthly basis.

The moves are part of government's revenue raising efforts to reduce revenue and fiscal deficit, official sources said.

The proposals were first announced by Finance Minister P Chidambaram in his budget speech.

"Help centres for small taxpayers would aim at those who are liable to pay tax but do not do so because of their hesitance and other fears about tax," an official in the finance ministry said.

The help centres would eye small traders and professionals whose turnover or income is Rs 500,000 per annum or less, sources said.

The helpdesks would be set up in association with chambers and industry associations, besides NGOs, the sources said.

While these bodies would provide infrastructure for the desks, the income tax and customs and excise departments would send their officials to man them.

In Delhi, six help centres have so far been identified for income tax purpose to be set up at Karol Bagh, Shahdra, Okhla, Chandni Chowk, Rani Bagh and Rohini, Chief Commissioner Income Tax (Delhi), V S Vahi said.
