Connecticut State Tax: Overview
Property taxes in Connecticut are relatively high. However, Connecticut's income tax rates don't reach 7% — regardless of how much you earn. Additionally, some taxpayers will see lower income tax rates next year.
Connecticut also has a gift tax and an estate tax, but most residents won't need to worry about paying those taxes since they only apply to gifts and estates worth more than $12.92 million.
[Data for this state tax guide was gathered from several sources including the U.S. Census Bureau, the state’s government website, the Sales Tax Handbook, and the Tax Foundation. Property taxes are cited as a rate percentage rather than the assessed value.]

Connecticut State Tax: Income Taxes
Connecticut tax on retirement benefits: Social Security benefits are tax-exempt for single and married filing separately filers with an AGI (adjusted gross income) below $75,000. Joint and head of household filers won't have their Social Security benefits taxed as long as their AGI falls below $100,000.
Income from an annuity or pension is tax-exempt for joint filers with less than $100,000 of federal adjusted gross income and other taxpayers (including head of household) with less than $75,000 of federal AGI.
For 2023, 25% of income from IRA distributions is tax-exempt for filers who meet the same income guidelines set for pension and annuity income (less than $100,000 for joint filers and less than $75,000 for all other filers). Taxpayers who meet these guidelines can exempt a larger percentage of IRA distributions in the next few years.
- Eligible taxpayers can exempt 50% of IRA distribution income in 2024.
- Eligible taxpayers can exempt 75% of IRA distribution income in 2025.
- Income from IRA distributions will become completely tax-exempt for eligible taxpayers in 2026.
Note: Taxpayers can deduct 50% of teacher's retirement system (TRS) pension income. However, eligible taxpayers are only eligible to deduct the general pension or annuity income or the TRS income, not both.
The tables below reflect tax rates for the 2023 tax year. The 5% tax rate will be lowered to 4.5%, and the 3% tax rate will be lowered to 2% starting in the 2024 tax year.
