"In many cases, the service providers collect service tax from their clients but do not deposit it with the government," said CBEC member (service tax) Lipika Majumdar Roy Choudhury.
Giving details of some prominent cases, she said the oil and gas sector has admitted liability of Rs 150 crore, a construction services company Rs 18 crore, a security services firm Rs 86 crore and the pharmaceutical sector Rs 28 crore.
"CBEC would appeal to all service providers to comply with the law and pay service tax that is due. Failure to pay service tax will attract appropriate action under law including recovery of tax, interest and penalty. Prosecution and attachment of property are also envisaged in appropriate cases," she said.
Roy Choudhury said the department has realised Rs 2,000 crore during the current fiscal bringing down the service evasion amount to Rs 7,800 crore.
The Central Board of Excise and Customs (CBEC) had detected service tax evasion of Rs 5,000-6,000 crore in April-December period last fiscal.
Asked whether the department would be able to meet service tax collection target of Rs 1.24 lakh crore for the current fiscal, she said, "I am hopeful that we will achieve the target."
During the first 9 months of the current fiscal, the service tax collections has witnessed a growth of 34 percent, she added.
