Abatement adjustments for taxable services: revised air passenger abatement and CENVAT credit condition alters service tax computation. Amendment to Notification No.26/2012 revises abatement table entries: it substitutes the column (4) entry for Sl. No. 2 to require that CENVAT credit on inputs, capital goods and input services used for providing the taxable service has not been taken under the CENVAT Credit Rules, 2004; makes Sl. No. 3 the same; omits Sl. No. 8; substitutes Sl. No. 5 to segregate air passenger transport into economy and other than economy with abatement entries and the same CENVAT credit non-taken condition; and alters column (3) entries for Sl. Nos. 7 and 10. The notification prescribes its commencement date.
