The Connecticut estate tax in 2026: what executors and heirs should know about a loved one's home.
The short version: for someone who passes away in 2026, Connecticut's estate tax exemption is $15 million, and the great majority of probate estates, including nearly every family home in New Haven and its surrounding towns, owe nothing at all. Even so, every executor files a simple notice form with the probate court within six months of death, so it helps to understand how the estate tax fits into the process before it comes up in conversation. This guide walks you through the 2026 rules, where the family home counts, and what actually needs to happen, in plain, gentle language.
What the Connecticut estate tax is, and what it is not.
When families hear the phrase "estate tax," they often worry it means the government will take a share of everything, including the home. In Connecticut today, that worry is almost always unfounded, but it is easy to see why the confusion lingers. There are several different taxes and fees that sound alike, and sorting them out brings real peace of mind:
- The Connecticut estate tax is a tax on the estate itself, the total value of what the person owned, calculated after deductions, and it is only owed when the taxable estate exceeds the exemption. You can read more about the changes in our overview of Connecticut probate law updates.
- There is no Connecticut inheritance tax. Unlike a handful of other states, Connecticut does not tax the people who receive the assets. Whatever your family inherits is not taxed again at the state level simply because it was inherited.
- Income tax on a sale is a separate question. If the estate sells the home, capital gains are generally measured from a "stepped-up" basis, the value at the date of death, which usually keeps the gain small or nonexistent. Our guide to the tax implications of selling a probate home explains that in detail.
- Probate court fees are their own small matter. The court charges modest filing fees for the estate case itself. Those fees are routine and are unrelated to the size of your family's estate.
- Medicaid estate recovery is also separate. If a loved one received long-term care benefits through Medicaid, a claim against the estate may exist, but that is a reimbursement program, not an estate tax. We cover it gently in our Medicaid and the family home guide.
The takeaway: going through probate does not mean paying an estate tax. For the vast majority of Connecticut families, the estate tax is simply not part of the picture, and the steps that remain are manageable.
The $15 million exemption, the headline for 2026.
Connecticut pegs its estate tax exemption to the federal basic exclusion amount under state law, and that figure rose for deaths that occur in 2026. Here is the current picture, in the numbers that matter:
$15M
2026 exemption
For decedents dying in 2026, the Connecticut estate tax exemption is $15 million per individual, up from $13,990,000 for 2025 deaths (CT DRS, Conn. Gen. Stat. § 12-391).
12%
Flat rate above it
Connecticut uses a single flat rate: if the taxable estate exceeds the exemption, the tax is 12 percent of the excess. Estates at or below $15 million owe no Connecticut estate tax at all.
$0
For nearly every family
A typical New Haven-area estate, where the median home sells around $400,000 (Redfin, September 2026), sits a long way below the threshold.
Two deductions keep the practical threshold higher still. Property that passes to a surviving spouse is deductible through the unlimited marital deduction, and bequests to qualifying charities are deductible as well. For a widow or widower, those protections are built into the law, not something a family has to negotiate.
The exemption also means most estates never file a tax return with the state tax department at all. The one document that does apply to nearly every estate is the simple notice we describe in section 05.
Where the family home fits into the picture.
Here is the part families ask about most: does the home count toward the estate? Yes, in a simple sense. The Connecticut estate tax is calculated on the value of everything the person owned, and the home is included at its fair market value on the date of death. That sounds more imposing than it is, for three reasons:
- The value that counts is realistic. The probate court requires an appraisal of the home for its own purposes, and that same honest, current valuation is what represents the home in the estate. There is no special government estimate inflating the number. Our guide to probate appraisals in Connecticut walks through how that valuation works.
- Debts are deducted. A mortgage, an unpaid line of credit, and other legitimate debts of the estate reduce the taxable amount. The family home is not counted as if it were owned free and clear when it carries a loan.
- The cushion is enormous. To approach the $15 million exemption, an estate would need the home plus well over $14 million in other assets. In the New Haven area, where the median sale price is roughly $400,000 (Redfin, September 2026), that combination is extraordinarily rare.
The emotional part deserves naming too. A house is more than a line item on a form; it is forty years of birthdays and Sunday dinners. No part of the Connecticut estate tax asks your family to value those memories in the calculation. The number on the appraisal is just the number, and it is a relief to know how rarely it affects anyone's tax bill.
The form every Connecticut executor should know: CT-706 NT.
This is the piece of the estate tax world most families have never heard of, and it is the one that actually touches them. Even when no tax is owed, the executor must file Form CT-706 NT, the Connecticut Estate Tax Return for Nontaxable Estates, with the probate court for the district where the person lived, within six months of the date of death.
A few things to know so it does not feel alarming:
- It is a notice, not a bill. The form confirms the estate's total value sits below the exemption. It does not calculate tax, and filing it does not mean any tax is owed (CT DRS, 2026 Form CT-706 NT instructions).
- It goes to the probate court, not the tax department. For nontaxable estates, the filing lands with the court handling the estate itself, the same courthouse where the executor was appointed. No separate trip to the Department of Revenue Services is required.
- The six-month clock runs from death. It is easy to lose track of that calendar when the family is grieving, which is exactly why it is worth writing down now. The court staff and the estate attorney are used to helping families meet it.
- It pairs with the inventory. The executor also files an inventory of estate assets with the court around the same period, and the home's appraisal becomes part of that inventory. The two documents fit together naturally. Our guide to the executor's role in Connecticut probate lays out the full list of duties.
If the estate's taxable value does exceed the exemption, the process changes: the executor files Form CT-706/709 with the Department of Revenue Services, with a copy to the probate court, and any tax is due within six months of death. For families in that rare situation, an experienced estate attorney should guide the filing from the start. We sketch what that looks like in section 06.
Watch: Understanding the Process
The executor's responsibilities sit at the heart of every Connecticut probate case, and knowing which forms go to which office is a big part of them. This short video walks through how the process unfolds, from the first filing to the final steps, so your family can move forward with a clear picture of what happens next.
When an estate does exceed the exemption.
Very few estates cross the $15 million line, but if yours does, the rules are straightforward and worth understanding rather than fearing. The tax is a flat 12 percent of the amount above the exemption, so only the excess is taxed, not the whole estate. The executor files Form CT-706/709 with the Department of Revenue Services and the probate court, and both the return and any tax due are handled within six months of death.
In that rare case, the standard protections still apply: the unlimited marital deduction can postpone or eliminate the tax for a surviving spouse, and charitable bequests are deductible. This is also the moment to bring in an estate attorney early. The cost of careful planning is far smaller than the tax a misstep could create, and a good attorney will make the process feel steady rather than overwhelming.
For everyone else, and that means the overwhelming majority of probate families in New Haven, Bridgeport, Hartford, and across Connecticut, the estate tax is a short, calm conversation, not a bill. The form that needs signing is the CT-706 NT notice, and section 08 shows how the pieces fit into your family's calendar.
What this means for a New Haven family home.
When I sit with a family in the New Haven area, the estate tax rarely turns out to be the number that matters. Here is the local context that makes that true:
$400K
New Haven median sale price
Redfin's most recent data put New Haven's median sale price near $400,000, up about 8.1 percent from a year earlier. Keep that number in view: it is roughly 2.7 percent of the $15 million exemption.
~49 days
Average time on market
Homes in New Haven have been going under contract in roughly 49 days, a pace that rewards pricing a probate home honestly and presenting it well.
39.96
New Haven mill rate
For the 2025 Grand List, billed July 2026 through June 2027, the city's real estate mill rate is 39.962, assessed at 70 percent of fair market value (City of New Haven Tax Collector).
Putting those numbers together, the picture for a probate family is reassuring. The home, even at today's prices, is a tiny fraction of the estate tax threshold. The financial items that deserve the family's attention are the practical ones, property taxes and insurance while the home sits vacant, the mortgage if one remains, and the market timing of the sale, not a state estate tax bill.

A warm, practical checklist for executors this year.
None of this needs to happen all at once, and none of it needs to happen alone. Here is the path we guide families through, one gentle step at a time:
- 1Open the estate and get appointed. The court appoints the executor, who then has the authority to act for the estate. This first step unlocks everything else.
- 2Mark the six-month date on the calendar. The CT-706 NT notice and the estate inventory both run on a deadline from the date of death. Writing it down today takes the pressure off later.
- 3Get an honest appraisal of the home. The court's probate appraisal serves the inventory and gives the estate a realistic number. It also anchors the conversation about listing price when the home is sold.
- 4List debts and deductions. Mortgage balances, unpaid bills, and estate expenses all belong in the record. They reduce the taxable estate and they must be handled before heirs receive their share. Our guide to estate debts and creditor claims explains the deadlines.
- 5Keep the home protected. Insurance in force, property taxes current, and the heat at a safe level if the home is vacant. A well-cared-for home preserves its value for whoever inherits or buys it.
- 6Call in the right help. An estate attorney for the paperwork, and a real estate professional who understands probate sales for the home. You are not expected to carry this alone.
Why probate experience matters when a home is involved.
The estate tax may not be the number that keeps you up at night, but the rest of the probate process still asks a grieving family to make careful decisions about a home full of memories. That is why the real estate side benefits from someone who has walked it before, an agent who understands both the court's requirements and the local market.
An agent who knows probate can help your family:
- Work alongside the executor and the estate attorney so the appraisal, inventory, and court filings line up with the sale.
- Price the home from fresh market data, using the probate appraisal as the court document it is, not a ceiling or a floor.
- Navigate the court confirmation of the sale and prepare the paperwork for a smooth approval.
- Keep every heir informed with clear, compassionate communication, including family living out of state.
- Decide, without pressure, whether selling now, holding for later, or keeping the home is the right path for the family.

Your practical takeaways for peace of mind.
If you remember nothing else from this guide, remember these six things:
- ✓The 2026 Connecticut exemption is $15 million. For deaths in 2026, estates at or below that amount owe no Connecticut estate tax, and the figure tracks the federal basic exclusion under state law.
- ✓Most estates owe nothing. A home worth around $400,000, the New Haven median, is a fraction of the threshold, and only the amount above the exemption is ever taxed.
- ✓The CT-706 NT notice still applies. Every executor files this form with the probate court within six months of death, even when no tax is due. It is a notice, not a bill.
- ✓Married and charitable situations are protected. The unlimited marital deduction and charitable deductions keep the practical threshold even higher for many families.
- ✓The estate tax is not the big number for your family. Property taxes, insurance, the mortgage, and market timing deserve more attention, and those are all things a good team helps you manage.
- ✓You are not alone in this. Thousands of Connecticut families walk this same path every year, and the right help makes each step feel smaller and more manageable.
