Short-term capital gains tax rate change: a higher rate now applies to transfers on or after the amendment date. The amendment makes tax on total income the aggregate of tax on short-term capital gains at the rate applicable to the date of transfer and tax on the balance of total income as if that balance were the taxpayer's total income; it applies different rates for transfers before the effective date and for transfers on or after the effective date, and replaces the first proviso to reference the rate applicable in clause (i), with effect from the effective date.
