Hartford's 2027 Tax Agenda: Targeting Greenwich High Earners, Hurting All CT Residents

State Rep. Tina Courpas (R–District 149, covering mid- and backcountry Greenwich) recently released a compelling message to constituents as she campaigns for re-election this fall.
Her warning is clear: If the Democratic supermajority in Hartford maintains control, they plan to vote on three new tax proposals in 2027 that target Connecticut’s highest earners. Here is what could be in store for local residents:
1.Annual Statewide Surcharge on Homes Over $3 million
A proposed statewide property tax surcharge on homes valued over $3 million. For example, a house assessed at $3 million would face an additional $3,000 annual tax burden. Passing this would make Connecticut one of only 16 states with a mansion-style property tax surcharge. (In a market like Greenwich, few homes actually fall under that $3 million threshold.)
2.A New Capital Gains Surcharge
A proposed 1.75% state surcharge on capital gains, making Connecticut one of only three states to levy such a tax. (High-growth sectors—like AI entrepreneurs generating extraordinary wealth—will simply choose to set up shop in tax-friendly states rather than Connecticut.)
3.A Spike in the Top Personal Income Tax Rate
An increase in the top state personal income tax rate from 6.99% to 7.99%. Connecticut already maintains one of the most progressive tax structures in the nation.
Currently, CT classifies single filers earning over $500,000 as "high earners." Crucially, that threshold includes wages, capital gains, dividends, interest, and realized real estate or business sales. (It doesn't take much to trigger this top bracket if you sell a business or realize gains in the stock market.)
"Bills like these are exactly why people are leaving Connecticut for states with less punitive tax structures, like Florida, Tennessee, and Texas."— State Rep. Tina Courpas
Between the Lines: When state policy continuously targets high earners, those taxpayers eventually relocate. When they leave, the tax base shrinks—leaving the remaining residents to pick up the tab for lost state revenue. Ultimately, this high-tax agenda doesn't just hit the wealthy; it hurts every taxpayer across Connecticut.
