Connecticut to Texas Retirement Taxes (2026): Every Tax That Changes

Updated July 26, 2026. Quick answer (2026): Moving from Connecticut to Texas in retirement, you stop paying Connecticut income tax on withdrawals and leave a Connecticut death tax behind. Four separate taxes change when you move — state income tax on withdrawals, state estate tax, state inheritance tax, and what probate costs your heirs. Most comparisons only price the first one.

1. What changes on your annual tax bill

Connecticut taxes retirement withdrawals: Pension/annuity income: 100% deduction below the same $75,000/$100,000 AGI thresholds; Texas does not. On a $100,000 annual withdrawal, the Connecticut bill is whatever its graduated to 6.99% (6 brackets, 2%-6.99%) schedule produces; in Texas it is $0. Social Security is treated as follows — Connecticut: Fully exempt if federal AGI < $75,000 (single/MFS/HOH) / $100,000 (MFJ). Texas: Not taxed (no state income tax).

2. What changes at death: state estate tax

This is usually the larger number. Connecticut levies an 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) — and Texas levies none (none). Establishing domicile in Texas removes that exposure for assets that are not Connecticut real property.

3. What changes at death: state inheritance tax

Neither state levies an inheritance tax. Connecticut: none Texas: none

4. The one nobody prices: what probate costs your heirs

Connecticut uses a reasonable-fee fee model (Fiduciary and attorney compensation is a ‘reasonable compensation’ standard (case law: Hayward v. Plant factors); no statutory percentage for compensation. BUT Connecticut’s probate COURT fees are statutory and percentage-based on the gross estate (C.G.S. §45a-107) — a distinctive cost driver, e.g., $1,865 + 0.25% of the amount over $500,000; capped at $40,000 (deaths on/after July 1, 2016); ~50% reduction when the spouse is sole beneficiary.); Texas uses a hybrid model (Executor/administrator standard compensation is statutory (Tex. Estates Code §352.002): 5% commission on cash actually received plus 5% on cash actually paid out (excluding e.g. cash on hand/bank deposits at death and distributions to heirs), capped in aggregate at 5% of the gross fair market value of the estate subject to administration. Attorney fees are reasonable. Note: most Texas probates are independent administrations where compensation is often governed by the will. Verified.). Filing fees — Connecticut: 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 Texas: County clerk / statutory probate court fees vary by county; typically ~$250-$450 to file an application for probate. Representative range from county schedules, not verified against a single official statewide source.

Full detail: probate cost by state and small-estate limits by state.

Probate cost in each state, specifically

Connecticut uses a “reasonable fee” standard with no schedule, and its small-estate route does not clear a solely owned house. Texas uses a hybrid standard — a statutory bound with reasonableness inside it, and its statute does not say whether that route reaches real property. The two states differ on that question, which is exactly the kind of thing a move changes. Full figures with the governing statute, the court filing fee and the small-estate threshold: Connecticut probate cost and Texas probate cost.

Four taxes, two states, one order of operations

Everything above changes together: what Connecticut stops taking on withdrawals, what Texas does not take at death, and what probate costs in each. The order you do things in — when you establish domicile, when you convert, when you retitle property — changes the total, and some of it cannot be undone afterwards. If a move is genuinely on the table, here is what to look for in an advisor who knows both Connecticut and Texas. If you would rather price it yourself first, the two-state comparison tool is free and asks for no email.

Will Connecticut still tax me after I move to Texas?

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 a mailing address. A departing state can and does audit residency. Days present, voter registration, driver’s licence, where your doctors and advisers are, and where you keep what you value all count.
• Real property left behind stays taxable. Keeping a home in Connecticut can keep part of the estate within reach of Connecticut rules even after you become a Texas resident.
• A Roth conversion is taxed where you live in the year you convert. Sequencing a conversion after establishing the new domicile is often worth more than the annual saving — see how all 51 jurisdictions tax Roth conversions.

If you keep a home in Connecticut, what happens at death?

Changing domicile moves you. It does not move the house. Connecticut levies an estate tax, and it reaches a nonresident decedent’s real property situated there — so a home kept behind after the move stays within Connecticut’s reach even once Texas is your legal home for every other purpose. A nonresident estate is one whose decedent was not domiciled in Connecticut but owned real or tangible personal property in Connecticut. Connecticut taxes transfers of Connecticut-situs real and tangible property.

If tax is due, file CT-706/709 with DRS. If no tax is due but clearance is needed, file CT-706 NT with the Probate Court for the district where the property sits. The practical consequence is the part most summaries skip: a filing can be required for clearance even when no Connecticut tax is due. Authority: Form CT-706/709 and CT-706 NT instructions.

This is the exposure that survives a move, and it is the one worth pricing before the move rather than after. The house also stays within that state’s probate jurisdiction, so the estate faces a separate ancillary proceeding there on top of the probate where you live — the ancillary probate calculator prices that second proceeding. Confirm the current figures with the state revenue department or a licensed professional before acting — thresholds move, and the arithmetic depends on the whole estate, not just the house.

Talking this through

Relocation timing, Roth conversion sequencing and estate exposure interact, and the order you do them in changes the total. If you want a second opinion, understand what it should cost first — see our advisor cost guide.
