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.

Strategies to reduce your 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 the tax-efficient withdrawal sequence.

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

Modeling your retirement taxes

The interaction between Connecticut's tax rules and federal taxes is too complex to estimate by hand. A year-by-year projection shows your actual tax burden for every year of retirement.

Drawdown Arc's projection engine includes Connecticut's full bracket structure, standard deduction, and retirement income exemptions. Set your state to Connecticut and enter your account balances, pension, and Social Security timing: the projection shows your Connecticut state tax alongside federal tax for every year.
