The Rhode Island estate tax applies to estates worth more than $1,838,056 for deaths occurring in 2026, at progressive rates from 0.8% to 16%.1Rhode Island Division of Taxation. 2026 Tax Changes The return and full payment are due within nine months of the date of death. Because the state threshold sits far below the federal exemption of $15,000,000, many Rhode Island families owe state estate tax even when they owe nothing to the IRS.2Internal Revenue Service.

The 2026 Threshold and How It Changes
For anyone who dies on or after January 1, 2026, Rhode Island exempts net taxable estates of $1,838,056 or less. Above that, tax is calculated on the full net estate and then reduced by a credit of $87,940, which is what produces the effective exemption.1Rhode Island Division of Taxation. 2026 Tax Changes
The threshold rises every year. State law ties a base credit amount of $64,400 to the Consumer Price Index for All Urban Consumers, compounding each January 1.3Justia. Rhode Island Code 44-22-1.1 – Tax on Net Estate of Decedent As the credit grows, so does the estate value at which tax first applies.
Why the State Bill Can Exceed the Federal One
The federal estate tax exemption for 2026 is $15,000,000 per person, more than eight times the Rhode Island threshold.2Internal Revenue Service. Whats New – Estate and Gift Tax A $5 million estate owes nothing federally but faces a real Rhode Island bill.
Rhode Island also does not offer portability between spouses. Under federal rules, a surviving spouse can carry over any unused portion of the deceased spouse’s exemption, effectively doubling the couple’s federal shelter to $30,000,000. There is no state equivalent. Each spouse gets only their own Rhode Island exemption, so couples who want to minimize state tax typically rely on credit shelter trusts rather than portability.
What Goes Into the Taxable Estate
The gross estate includes every asset the decedent owned or controlled at death: real estate, bank accounts, investment portfolios, retirement accounts, and business interests. Life insurance proceeds are included when the decedent held ownership rights over the policy, such as the ability to change beneficiaries or borrow against the cash value.
From the gross estate, the executor subtracts allowable deductions to reach the net taxable estate. Rhode Island’s return is modeled after federal Form 706, and the deduction schedules follow the same structure.4Rhode Island Division of Taxation. Form RI-706 Instructions Common deductions include funeral costs, legal and accounting fees incurred during probate, outstanding debts like mortgages, losses during administration, and charitable bequests to qualifying organizations.5Rhode Island General Assembly. Rhode Island Code 44-22-1 – Tax on Net Estate of Decedents
Assets passing to a surviving spouse may qualify for a marital deduction. Rhode Island law references the federal marital deduction under 26 U.S.C. § 2056, but the statute also sets a specific dollar limit on that deduction.5Rhode Island General Assembly. Rhode Island Code 44-22-1 – Tax on Net Estate of Decedents Executors handling large spousal transfers should confirm with a tax professional how much of the deduction applies to their situation.
How the Tax Is Calculated
Rhode Island calculates the tax using the state death tax credit table from old federal law (26 U.S.C. § 2011 as of January 1, 2001), then subtracts the $87,940 Rhode Island credit.3Justia. Rhode Island Code 44-22-1.1 – Tax on Net Estate of Decedent Rates run from 0.8% on the lowest taxable amounts up to 16% on estates above roughly $10 million.
Because the credit offsets tax on estates near the threshold, crossing $1,838,056 by a small margin does not trigger a large bill. An estate worth $1,850,000 would owe only the small difference between the tax computed on that amount and the credit. The pressure builds as the estate grows, and estates in the $2 million to $5 million range are where planning tends to matter most.
Non-Residents Who Own Rhode Island Property
Non-residents owe Rhode Island estate tax on real estate and tangible personal property physically located in the state. Intangible property like stocks, bonds, and bank accounts does not create state tax exposure for non-residents.6Rhode Island General Assembly. Rhode Island Code 44-22-1.1 – Tax on Net Estate of Decedent
When a non-resident’s estate holds both Rhode Island property and property elsewhere, the tax is prorated. The state multiplies the full calculated tax by a fraction with Rhode Island property in the numerator and the total gross estate in the denominator.6Rhode Island General Assembly. Rhode Island Code 44-22-1.1 – Tax on Net Estate of Decedent A non-resident with a $4 million total estate and a $1 million Rhode Island vacation home is taxed on one-quarter of what the full tax would have been.
Filing the Return
Form RI-706 and full payment are due within nine months of the date of death. The form mirrors federal Form 706 and requires a detailed inventory of every asset at fair market value as of the date of death, or an elected alternate valuation date applied uniformly to the entire estate.7Rhode Island Division of Taxation. Form RI-706 – Estate Tax Return
Executors needing more time can file Form RI-4768 before the nine-month deadline to receive an automatic six-month extension. A copy of any federal extension request (IRS Form 4768) should accompany the state form.8RI Division of Taxation. Estate Tax The extension covers paperwork only. It does not extend the deadline for paying the tax.
Every asset on the return needs supporting documentation. Bank and brokerage statements cover cash and securities; real estate and closely held business interests typically require professional appraisals. Gathering records early matters, because the form calls for detailed schedules covering jointly owned property, lifetime transfers, and more.
Interest on Late Payment
Unpaid balances accrue interest at 12% per year for 2026.9RI Division of Taxation. Interest Rates Interest starts running from the original nine-month due date regardless of any filing extension. Additional penalties may apply for failure to file within the extension period or failure to pay the balance due.
At 12% annually, delay is expensive. A $50,000 tax bill accrues $500 in interest each month. Executors who know the estate is taxable but are still refining the numbers should make an estimated payment by the nine-month mark and reconcile when the return is complete.
The Lien on Real Estate
Rhode Island places an automatic lien on a decedent’s real property to secure any potential estate tax debt. Even for estates below the taxable threshold, the lien has to be formally released before the property can be sold or transferred with clean title. The discharge requires filing Form T-77 with the Division of Taxation, and a separate form is needed for each property.10Rhode Island Division of Taxation. Form T-77 Discharge of Estate Tax Lien Executors planning to sell inherited real estate should build the lien release timeline into their schedule from the start.
