Clubbing of family income risks expanding under revised spouse professional-income wording, increasing compliance and valuation complexities.
Section 99 requires inclusion in an individual's total income of amounts arising to a spouse, son's wife, minor child, or where property is converted into HUF property; it prescribes exclusions for certain minor child earnings, a proportionate apportionment formula for assets invested in business or partnership, deems income to include loss, preserves a temporal carve out for conversions on or before 31 December 1969, and identifies documentation and valuation consequences where Bill wording diverges on spouse professional income carve outs, third party benefit attribution and the denominator reference date for apportionment.
