Retirement Tax in Connecticut: Complete Guide 2026

Tax information is for educational purposes only and does not constitute tax advice. Consult a licensed tax professional for your specific situation.

Connecticut has been gradually expanding its exemptions for retirement income, but the state still taxes certain types of retirement income depending on your income level and the source of the funds. With a top income tax rate of ~6.99% plus surcharges for high earners, understanding which retirement income is exempt and which is taxable is essential for Connecticut retirees looking to minimize their state tax burden.

Connecticut Retirement Income Tax Treatment

Retirement Income Type	Tax Treatment
Social Security benefits	Exempt below AGI threshold; partially taxable above
Teacher/state pensions (CT)	Exempt up to ~25% (increasing to ~50% for some)
Federal government pensions	~100% exempt
Military retirement pay	Fully exempt
Private pensions	Taxable (some exemptions)
401(k) distributions	Taxable (some exemptions for lower income)
Traditional IRA distributions	Taxable (some exemptions for lower income)
Roth IRA distributions	Tax-free (also federal)

Connecticut has been phasing in a full exemption for Social Security benefits. The exemption depends on your adjusted gross income:

Filing Status	Full Exemption Below	Partial Taxation Above
Single	AGI under ~$75,000	Phased in above ~$75,000
Married filing jointly	AGI under ~$100,000	Phased in above ~$100,000

For taxpayers above the thresholds, Connecticut taxes the same percentage of Social Security that is taxable federally, up to ~85% of benefits. However, the state has been reducing this tax and expanding the exemption threshold.

Example

A married couple with ~$80,000 AGI and ~$30,000 in Social Security:

AGI below ~$100,000 threshold: Social Security is fully exempt
Connecticut tax on SS: ~$0

A single filer with ~$90,000 AGI and ~$25,000 in Social Security:

AGI above ~$75,000 threshold: A portion is taxable
Taxable portion calculated based on excess above threshold

Pension Exemptions

State and Teacher Pensions

Connecticut has been increasing the exemption for state employee and teacher pensions. For 2026, qualifying recipients can exempt approximately ~25% to ~50% of pension income, with the exact percentage depending on legislative updates and income level.

Federal Pensions

Federal government pension income, including Civil Service Retirement System (CSRS) and Federal Employees Retirement System (FERS) pensions, is ~100% exempt from Connecticut income tax. This is a significant benefit for the state’s federal workforce.

Military Retirement

All military retirement pay is fully exempt from Connecticut income tax, regardless of income level or other factors.

Connecticut Retirement Tax Rates

For retirement income that is taxable, Connecticut’s graduated rates apply:

Tax Rate	Single Filer Income	Married Filing Jointly
~3%	$0 - ~$10,000	$0 - ~$20,000
~5%	~$10,001 - ~$50,000	~$20,001 - ~$100,000
~5.5%	~$50,001 - ~$100,000	~$100,001 - ~$200,000
~6%	~$100,001 - ~$200,000	~$200,001 - ~$400,000
~6.5%	~$200,001 - ~$250,000	~$400,001 - ~$500,000
~6.9%	~$250,001 - ~$500,000	~$500,001 - ~$1,000,000
~6.99%	Over ~$500,000	Over ~$1,000,000

A ~10% surcharge applies to higher-income taxpayers, potentially pushing the effective top rate to approximately ~7.69%.

Connecticut vs. Neighboring States

State	SS Taxed?	Pensions Taxed?	401(k)/IRA Taxed?	Top Rate
Connecticut	Partially (income-based)	Partially	Yes (with some exemptions)	~6.99%
New York	No	Exempt up to ~$20,000 (age ~59.5+)	Exempt up to ~$20,000	~10.9%
Massachusetts	No	Taxable	Taxable	~9%

New Jersey	No	Exempt up to ~$150,000 (age ~62+)	Exempt up to ~$150,000	~10.75%

Tips for Connecticut Retirees

Monitor the Social Security exemption threshold. If your AGI is near the ~$75,000 (single) or ~$100,000 (joint) threshold, reducing your AGI by even a small amount could fully exempt your Social Security benefits. Strategies include maximizing retirement account deductions and timing Roth conversions. See our federal income tax guide.
Maximize the federal pension exemption. If you receive a federal government pension, ensure it is properly subtracted on your Connecticut return. This ~100% exemption can save thousands annually.
Consider income sequencing. Draw from tax-free sources (Roth accounts, tax-free bonds) in years when staying below the Social Security exemption threshold is possible. This keeps your AGI low enough to preserve the full SS exemption.
Evaluate property tax credits. Connecticut offers property tax credits for eligible seniors through various municipal and state programs. The state Property Tax Credit provides up to ~$200 for qualifying homeowners age ~65+ with income below certain thresholds.
Plan for the surcharge. If your income is high enough to trigger the ~10% surcharge, explore strategies to reduce taxable income such as charitable giving, Roth conversions (if timing is favorable), or installment sale elections on asset sales. Check our self-employment tax guide for additional planning strategies.
Use the PTE tax if applicable. If you have pass-through business income in retirement, Connecticut’s mandatory pass-through entity tax provides a workaround for the SALT deduction cap, effectively allowing a deduction at the entity level.
Evaluate relocation timing. Connecticut’s relatively high rates on retirement income may make relocation attractive for high-income retirees. If you are considering a move, establish residency in the new state before the tax year begins to maximize savings. Use our tax bracket calculator to compare states.
