Service tax exemption for residential construction limits taxable value; exceptions include CENVAT credit, prior notification benefit, finishing services. Exempts a portion of service tax on taxable services for construction of residential complexes by restricting tax to that calculated on a value equivalent to thirty-three percent of the gross amount charged; the exemption excludes cases where CENVAT credit has been taken, where benefit under an earlier notification has been availed, or where services are only completion and finishing services. The notification defines gross amount charged to include the value of goods and materials supplied or used by the service provider and states the effective commencement date.
