Connecticut High-Income Tax Strategies (2026)

Why Connecticut Requires Careful Planning

Connecticut has a progressive income tax reaching 6.99% at the top, plus a benefit recapture that pushes some high earners to an effective flat 6.99% on all income. Combined with high property taxes and proximity to New York, Connecticut high earners — many of them finance professionals — need coordinated planning.

The combined federal and Connecticut marginal rate is approximately 44%.

Connecticut's Income Tax Structure

• Progressive rates from 2% to 6.99%
• Benefit recapture phases out the lower brackets for high earners, effectively taxing all income at 6.99%
• Capital gains taxed as ordinary income
• High property taxes, especially in Fairfield County

The Benefit Recapture Detail

For a single filer above approximately $540,000 (or married above ~$1,000,000), the recapture eliminates the benefit of the lower brackets, so the full income is effectively taxed at 6.99%.

Capital Gains

On a $2 million gain:

• Connecticut tax: 6.99% × $2,000,000 = $139,800
• Federal tax at 23.8%: $476,000
• Combined: $615,800

Core Strategies for Connecticut High Earners

1. Pass-Through Entity Tax (PET) Election

Connecticut has a mandatory/elective pass-through entity tax allowing entity-level payment deducted federally, working around the SALT cap.

Example: $2 million S-corp:

• Connecticut tax: 6.99% × $2M = $139,800 (deducted federally)
• Federal benefit recovered: 37% × $139,800 = $51,726

2. Residency and the New York Commuter Issue

Many Connecticut residents work in New York. Income earned in New York is New York-sourced and taxed by New York, with a Connecticut credit for taxes paid to New York. Structuring work location and remote-work days affects sourcing.

For someone considering a move to Florida before a liquidity event, Connecticut and New York sourcing rules both apply — RSUs and deferred compensation earned while working in those states remain sourced there.

3. Real Estate Strategies

Cost segregation with 100% bonus depreciation reduces federal and Connecticut income.

Example: $4 million property, $700,000 reclassified:

• Year 1 deduction: $700,000
• Federal tax savings at 37%: $259,000
• Connecticut tax savings at 6.99%: $48,930
• Combined: $307,930

Short-term rental and REPS losses offset W-2 and business income.

Example: $1.5 million W-2 income, $250,000 STR loss with material participation:

• Combined tax savings at 44%: $110,000

4. Property Tax Management

Fairfield County property taxes are high. Property tax assessment appeals can recover meaningful overpayments.

Example: $5 million home over-assessed by $500,000 at a 1.5% rate:

• Annual overpayment: $500,000 × 1.5% = $7,500/year

5. Charitable and Retirement Planning

• Donor-advised fund gifts produce federal and Connecticut deductions and avoid capital gains tax
• Cash balance and 401(k) contributions reduce federal and Connecticut income

Example: $180,000 cash balance contribution saves approximately $79,182 combined.
