Service tax paid on exempt legal services is a refundable deposit, unaffected by statutory refund limitation or unjust enrichment.
Service tax paid under reverse charge on exempt legal services, where the taxable value remains below the threshold, is treated as a deposit rather than tax legally due. An advance received for proposed services but recovered after contract termination, without any service being rendered or consideration retained, does not form turnover for threshold-exemption purposes. Reversal of unutilised CENVAT credit removes the related objection to exemption. As no tax liability arises, the one-year refund limitation under Section 11B does not apply. Refund is also not barred by unjust enrichment where the tax incidence was not passed on and the claimant bore the burden.
Issues: (i) Whether service tax paid under reverse charge on legal services was paid under a mistake of fact; (ii) Whether exemption under Sl. No. 6(b) of Notification No. 25/2012-ST dated 20.06.2012 was available; (iii) Whether the refund claim was barred by the limitation under Section 11B of the Central Excise Act, 1944 as applied by Section 83 of the Finance Act, 1994; and (iv) Whether unjust enrichment barred the refund.
Issue (i): Whether service tax paid under reverse charge on legal services was paid under a mistake of fact.
Analysis: The taxable value in each relevant financial year was below the prescribed threshold, and the recipient was therefore not liable to pay service tax under reverse charge on the legal services. The payment made despite the exemption was not a payment of legally due tax.
Conclusion: The service tax paid under reverse charge was paid under a mistake of fact, in favour of the assessee.
Issue (ii): Whether exemption under Sl. No. 6(b) of Notification No. 25/2012-ST dated 20.06.2012 was available.
Analysis: Although service tax became payable on receipt of an advance under the Point of Taxation Rules, the advance received for proposed mining services was subsequently recovered upon termination of the contract and no service was rendered. It was neither recognised as income nor retained as consideration for services. Such recovered advance could not constitute turnover for determining threshold eligibility. The reversal of unutilised CENVAT credit on legal services also removed the objection to the exemption.
Conclusion: The recovered advance was not turnover, and the assessee was eligible for the threshold exemption on legal services under reverse charge, in favour of the assessee.
Issue (iii): Whether the refund claim was barred by the limitation under Section 11B of the Central Excise Act, 1944 as applied by Section 83 of the Finance Act, 1994.
Analysis: Since the amount was paid despite there being no service-tax liability, it was a deposit and not tax legally payable. The one-year limitation governing a refund of duty or tax under Section 11B was consequently inapplicable.
Conclusion: The refund claim was not time-barred, in favour of the assessee.
Issue (iv): Whether unjust enrichment barred the refund.
Analysis: The contractual advance had been recovered through enforcement of the bank guarantee, leaving no occasion to pass the service-tax incidence to another person. A Chartered Accountant certificate also supported that the tax burden had been borne by the assessee.
Conclusion: The doctrine of unjust enrichment did not apply, in favour of the assessee.
Final Conclusion: The amount paid on exempt legal services is refundable as a deposit, free from the statutory limitation and unjust-enrichment objections.
Ratio Decidendi: An amount paid as service tax where no tax liability arises due to an applicable exemption is a deposit; its refund is not governed by the limitation under Section 11B where the tax incidence has not been passed on.
