Section 01

Connecticut's retirement
tax landscape

Social Security is exempt if income is below $75,000 (single) / $100,000 (married). Pensions and retirement account withdrawals are fully taxable with no special exclusion.

Understanding how Connecticut treats each type of retirement income is essential for planning your withdrawals, conversions, and Social Security timing. The interaction between state and federal taxes determines your true after-tax income each year.

💡
State and federal taxes are independent
Connecticut calculates its own deductions and exemptions separately from the federal return. Income that falls below the federal standard deduction may still be taxable in Connecticut, and vice versa. Plan for both independently.
Section 02

Section 03

Connecticut's
tax brackets

Connecticut uses progressive tax brackets with a top rate of 6.99%. For single filers: 2% up to $10,000, 4.5% to $50,000, 5.5% to $100,000, 6% to $200,000, 6.5% to $500,000, 6.9% to $1,000,000, 6.99% above $1,000,000 (single). The standard deduction is $15,000 for single filers and $24,000 for married filing jointly.

Connecticut's brackets rise gradually to 6.99%. Most moderate-income retirees fall in the middle brackets.

📊
Top rate: 6.99%

Progressive rates mean each dollar is taxed at its own bracket rate. The marginal rate on the next dollar matters most for planning.

📊
Standard deduction

$15,000 single / $24,000 married filing jointly. Income below this threshold is tax-free at the state level.

Section 04

Strategies to reduce your
Connecticut tax burden

Managing total income to stay below the $75,000/$100,000 SS exemption threshold is critical. The generous standard deduction ($15,000/$24,000) shelters significant income. Federal tax planning — withdrawal sequencing and SS timing — drives the primary savings opportunity.

Roth conversions before retirement. Converting traditional IRA balances to Roth during lower-income years means paying Connecticut tax now at lower rates, then taking tax-free Roth withdrawals later. See the full Roth conversion strategy guide.

Withdrawal sequencing. The order you draw from different accounts each year matters. Drawing from taxable brokerage accounts before tapping tax-deferred accounts can keep your Connecticut ordinary income lower. Read more in which accounts to withdraw from first.

Social Security timing. Optimizing when you claim Social Security affects both your federal and state tax picture. See when to start Social Security.
