Connecticut tax rules to know
Key points from our 2026 Connecticut data, compiled from the official sources listed at the end of this page:
- Rates unchanged for 2026 (DRS: 2026 withholding rules and tables are unchanged from 2025). Married filing separately uses the single brackets.
- No standard deduction and no dependent exemptions. Personal exemption (deducted from CT AGI): $15,000 single, $24,000 MFJ, $19,000 head of household, $12,000 MFS; reduced by $1,000 for each $1,000 (or part) of CT AGI above $30,000 single / $48,000 MFJ / $38,000 HOH / $24,000 MFS, reaching $0 at $44,000 / $71,000 / $56,000 / $35,000.
- 2% rate phase-out add-back: higher earners lose the benefit of the 2% bracket - add $25 per $5,000 of CT AGI above $56,500 (single, max $250), $50 per $5,000 above $100,500 (MFJ, max $500), $40 per $4,000 above $78,500 (HOH, max $400), $25 per $2,500 above $50,250 (MFS, max $250).
- Tax benefit recapture: additional tax that phases in at high incomes so the top taxpayers effectively pay the top rate on all income - single/MFS from $105,000, MFJ from $210,000, HOH from $168,000, in three tiers up to a maximum of $3,400 (single/MFS), $6,800 (MFJ), $5,320 (HOH).
- Personal tax credit: after computing tax (brackets + add-back + recapture), low- and middle-income filers reduce it by 1%-75% based on CT AGI (e.g., single: 75% up to $18,800, 10% from $33,300 to $60,000, 0% above $64,500).
- Connecticut also offers a property tax credit (up to $300, limited eligibility) and exclusions for Social Security and pension/IRA income below income limits.
- Tax calculation order (CT-1040 TCS): taxable income = CT AGI - personal exemption; tax = bracket tax + 2% add-back + recapture; then multiply by (1 - personal credit decimal).
Local income tax: none. Cities and counties in Connecticut do not levy their own income tax in our 2026 data.
