What This Bill Proposed
Starting with the 2027 tax year, Connecticut imposes a 1.75% surcharge on net capital gains for individual taxpayers with adjusted gross incomes meeting specific high-income thresholds. Affected filers must submit a report and remit payment to the Department of Revenue Services by April 15 following each tax year. The measure provides a one-time exclusion for capital gains from selling a primary residence or a business ownership interest.
High-income resident taxpayers face an additional 1.75% tax levy on capital asset sales, generating an estimated $260 million annually for the state General Fund beginning in 2028 while funding new administrative positions and technology upgrades at the Department of Revenue Services.
