Service tax limitation and revenue neutrality depend on proof of suppression, documentary support, and the true nature of the services.

Classification of an activity as taxable service depends on its substance and contractual reality, and non-payment disclosed only in audit can support suppression and invocation of the extended limitation period. Waiver of penalty on reasonable cause does not, by itself, negate the demand or the finding of suppression. A plea of revenue neutrality must be proved with documentary support; where the assessee cannot show that the main contractor's tax payment covered the disputed receipts, the defence fails. The burden of rebutting taxability is not discharged by mere assertion that the main contractor paid service tax, and liability for taxable maintenance, management and repair services remains enforceable on the facts.

Issues: (i) Whether the extended period of limitation for demanding service tax was sustainable despite waiver of penalty on the ground of reasonable cause; (ii) whether the extended period could be invoked when revenue neutrality was not established; (iii) whether the burden lay on the Revenue to prove taxability where the main contractor had paid service tax.

Issue (i): Whether the extended period of limitation for demanding service tax was sustainable despite waiver of penalty on the ground of reasonable cause.

Analysis: The activity undertaken by the assessee fell within the taxable entry for management, maintenance and repair services. Non-payment of tax came to light only during audit, and the record did not establish disclosure of the taxable receipts. Waiver of penalty under the discretionary power did not nullify the finding of suppression or affect the validity of the demand for the extended period.

Conclusion: The extended period of limitation was rightly invoked and the issue was decided against the assessee.

Issue (ii): Whether the extended period could be invoked when revenue neutrality was not established.

Analysis: The claim of revenue neutrality was not proved, as the assessee failed to produce the breakup showing that the service tax paid by the main contractor covered the tax attributable to the assessee's receipts. The supposed credit linkage was therefore not accepted on the facts.

Conclusion: Revenue neutrality was not established and the issue was decided against the assessee.

Issue (iii): Whether the burden lay on the Revenue to prove taxability where the main contractor had paid service tax.

Analysis: The work order and the nature of the services showed that the assessee performed taxable maintenance, management and repair functions for consideration. In the absence of documentary proof that the main contractor's payment covered the disputed receipts, the assessee's plea of absence of independent liability was rejected.

Conclusion: The burden was not discharged by the assessee and the issue was decided against the assessee.

Final Conclusion: The demand of service tax and the Tribunal's view upholding it were sustained, while the penalty relief did not alter the tax liability.

Ratio Decidendi: Classification of an activity as taxable service depends on its substance and contractual reality, and waiver of penalty does not by itself defeat a demand founded on suppression and invocation of the extended period.
