The rule in plain language
| State | 2026 rule used here |
|---|---|
| Colorado | Colorado does not require an estate-tax filing for a death after December 31, 2004. The former state tax equaled the old federal state-death-tax credit. A Colorado resident can still owe estate tax to another state on real or tangible property located there. Colorado Legislative Council Staff, estate tax |
| Massachusetts | For a death on or after January 1, 2023, Massachusetts requires a return when the gross estate plus adjusted taxable gifts exceeds $2,000,000. The tax is the former federal credit for state death taxes (Internal Revenue Code as of December 31, 2000), reduced by a $99,600 credit, not below zero. For a death on or after August 1, 2025, real and tangible property outside Massachusetts is removed before that computation. A nonresident is tested on the worldwide estate and is taxed on Massachusetts real and tangible property. Massachusetts Estate Tax Guide |
| Connecticut | For a 2026 death, Connecticut Department of Revenue Services states a $15 million exemption and a tax of 12% of the amount over the federal basic exclusion, with a $15 million cap on the aggregate Connecticut gift and estate tax. This estimate adds lifetime taxable gifts entered here as a stand-in for Connecticut taxable gifts since 2005. Connecticut Department of Revenue Services, estate and gift taxes |
| Rhode Island | Rhode Island advisory ADV 2025-27 (December 30, 2025) sets the 2026 credit at $87,940, which exempts a net taxable estate of $1,838,056 or less. The credit is applied against the former federal state-death-tax table. Rates on that table run from 0.8% to 16%. Rhode Island Division of Taxation advisory ADV 2025-27 |
| Maine | For a 2026 death, Maine's exclusion is $7,160,000. The tax is 0% through that amount, 8% of the excess over $7,160,000 until $10,160,000, 10% of the excess over $10,160,000 plus $240,000 until $13,160,000, and 12% of the excess over $13,160,000 plus $540,000. Maine Revenue Services, estate tax |
| Vermont | Vermont's estate tax is 16% of the Vermont taxable estate over $5,000,000, subject to a situs fraction. A January 29, 2026 legislative brief says the $5 million figure is not pegged to inflation. This estimate applies 16% to the amount over $5,000,000, then multiplies by Vermont property divided by the gross estate. Vermont Department of Taxes, estate tax, and 32 V.S.A. § 7442a |
| New Hampshire | New Hampshire is not listed on the Tax Foundation estate and inheritance tax table as of October 1, 2026. This estimate uses zero for a New Hampshire estate tax. A Department of Revenue Administration page stating an estate-tax rate was not the source of that zero. A secondary law-firm page describes repeal of the legacy and succession taxes for deaths on or after January 1, 2003. Tax Foundation estate and inheritance tax table (as of October 1, 2026) |
In this worked example the Colorado estimate is $0 and the federal estimate is $0.
