Negative list taxation of services expands the taxable base while protecting input tax credit integrity and reducing distortions. A negative list approach would make all supplies meeting the proposed definition of 'service' taxable except specifically excluded items, aiming to broaden the base, protect input tax credit integrity, and reduce distortions from selective exemptions. The definition excludes goods, money and immovable property while including rights to use immovable property, temporary transfers of intellectual property, obligations to do or refrain from acts, and hire or lease of goods. An indicative sectoral negative list is proposed and operational changes to credit and point-of-taxation rules are identified for implementation.
