Commencement date amendment postpones the Finance Act section 11 effective date to July next year. The Central Government, exercising powers under the Finance Act, amends the principal notification S.O. 4419(E) by substituting the previously specified commencement day with a later calendar date, thereby changing the effective date of the provisions notified. A note records that an earlier substitution had set an intermediate commencement date which is now superseded by this amendment. The instrument is an administrative notification published by the Department of Revenue to revise the operative commencement timeline.
