Connecticut Paycheck Calculator 2026 — 6.99% Top State Rate (Federal + FICA + State)

How much do I take home in Connecticut? — short answer first

Connecticut runs a 7-bracket progressive income tax (2-6.99%) with a uniquely generous personal exemption ($24,000 single / $48,000 joint at the base) that phases out at higher incomes. The 2024 reform (HB 6941) dropped the bottom bracket from 3% to 2% on the first $10K of taxable income — providing meaningful relief for lower-income filers. Connecticut has no local income tax. NY commuters drive much of the state's tax friction: CT residents working in Manhattan file both states' returns and receive a CT credit for NY non-resident tax paid. There is no reciprocity. Connecticut has the second-highest property tax in New England (~1.79% effective, behind only NH).

net_pay     = gross − federal_tax − fica − state_tax − local_tax − pre_tax
federal_tax = Σ (federal_bracket × rate) on (gross − std_dev − 401k − hsa)
fica        = MIN(wages, $181K) × 6.2% + wages × 1.45% + add'l Medicare
state_tax    = Σ (bracket_amount × bracket_rate)    // top rate 6.99% in Connecticut
local_tax    = 0    // no local payroll tax in Connecticut

How Connecticut taxes payroll in 2026

Connecticut levies a 7-bracket progressive individual income tax under Conn. Gen. Stat. §12-700. Single filer brackets: 2% on the first $10,000 of taxable income (reduced from 3% under 2024 reform HB 6941); 4.5% on $10,001-$50,000; 5.5% on $50,001-$100,000; 6% on $100,001-$200,000; 6.5% on $200,001-$250,000; 6.9% on $250,001-$500,000; 6.99% above $500,000. Married-filing-jointly thresholds are exactly doubled. The 2% bottom bracket is new — dropped from 3% effective tax year 2024 under HB 6941, providing ~$300/year of relief for lower-income filers. Connecticut uses a unique personal exemption structure rather than a standard deduction: $24,000 single / $48,000 joint at the base, phasing out as AGI rises. The phase-out is steep: a single filer with AGI of $30,000 has the full $24,000 exemption; at $48,000 AGI the exemption is fully phased out. Combined with a tax credit for low-income filers, this effectively creates a 'donut' structure where lower earners pay very little and middle earners pay more aggressively than the headline 4.5-5.5% rates suggest. Connecticut has no local income tax — Hartford, New Haven, Stamford, Bridgeport, and Norwalk all fund services through property tax (effective rate ~1.79% statewide — second-highest in New England behind NH) and 6.35% sales tax (no local addition). There is no reciprocity with any neighbouring state. New York commuters — the largest CT working population — file the NY non-resident return AND the CT resident return, with CT crediting the NY tax paid on the same income. This is dual-filing burden but no double-taxation; the 'convenience of the employer' rule complicates the math for hybrid arrangements where a CT resident works partially from home for a NY-based employer.

How to use this calculator

1. Enter your annual gross salary. Pre-tax, what your employer pays before any deductions.
2. Pick filing status. Single, married filing jointly, married filing separately, or head of household. Drives both federal and Connecticut brackets.
3. Add 401(k) and HSA contributions (optional). Both lower your federal taxable income; HSA also lowers FICA wages.
4. Read the verdict. Annual + monthly + bi-weekly take-home, federal + state + local breakdown, and effective tax rate.

Common mistakes

• Confusing gross with adjusted gross. The calculator wants your gross salary — what your employer pays before any pre-tax deductions or contributions. If you enter your W-2 Box 1 (already net of 401k), the math will under-count your tax.
• Forgetting that 401(k) is still subject to FICA. Traditional 401(k) reduces federal income tax but NOT Social Security + Medicare. Only HSA (through payroll) reduces both.
• Using the wrong filing status for state tax. Connecticut uses the same filing status categories as the IRS, but bracket thresholds differ from federal. Pick the status that matches your actual tax filing — not just what gives the best number.
• Ignoring multi-state implications. If you work in Connecticut but live elsewhere (or vice versa), you may owe taxes in both states with a credit between them. This calculator assumes you both live and work in Connecticut.
