Updated July 25, 2026. Quick answer (2026): If you are weighing a move out of Connecticut in retirement, two things change when you leave Connecticut: a top income-tax rate of 6.99% on withdrawals, and a tax at death. Four taxes change when you move — income tax on withdrawals, state estate tax, state inheritance tax, and what probate costs your heirs. This page prices all four for Connecticut, then links a worked comparison for each destination.
What Connecticut actually charges a retiree
| Tax | Connecticut position, 2026 |
|---|---|
| State income tax | graduated to 6.99% (6 brackets, 2%-6.99%) |
| Social Security | Fully exempt if federal AGI < $75,000 (single/MFS/HOH) / $100,000 (MFJ). Above thresholds, at most 25% of benefits taxable (75% still exempt), limited to the federally taxable amount. |
| Pension / 401(k) / IRA | Pension/annuity income: 100% deduction below the same $75,000/$100,000 AGI thresholds; |
| Estate tax | yes – 2026 exemption $15,000,000 (statutorily tied to the federal basic exclusion amount); flat 12% rate on the excess; total tax capped at $15M; CT also levies the only state gift tax (unified with estate) |
| Inheritance tax | none |
| Probate fee model | reasonable-fee |
| Probate filing fee | No flat filing fee model — the value-based estate fee under C.G.S. §45a-107 functions as the court cost (see fee_basis); Connecticut Probate Courts publish an official calculator at ctprobate.gov |
| Small-estate limit | $40,000 — settlement of small estates without full probate (affidavit in lieu of administration), C.G.S. §45a-273: solely owned personal property only, no solely owned CT real property. |
Both halves matter
Connecticut taxes retirement withdrawals and levies a tax at death. A comparison that prices only the first will understate what a move is worth, sometimes by an order of magnitude, because the death-tax threshold is a one-off on the whole estate rather than a percentage of one year’s income.

Getting the sequence right
Leaving Connecticut cleanly is a sequencing problem as much as a tax one: domicile tests, what happens to property you keep behind, and the order of conversions and sales. See finding an advisor for a cross-state move for what to look for and the five questions to ask first.
Will Connecticut still tax me after I move away?
Not on your retirement withdrawals, once you genuinely change domicile — but that is a harder test than a change of address, and what you leave behind stays in reach.
- Domicile is a test, not an address. Connecticut can audit a departing resident. Days present, licence, registrations, where your advisers are and where you keep what you value all count.
- Property left behind stays reachable. Keeping a home in Connecticut can keep part of your estate inside Connecticut rules.
- Sequence any Roth conversion. It is taxed where you are domiciled in the year you convert — see how all 51 jurisdictions tax Roth conversions.
