Rhode Island Estate Tax Exemption 2026: Threshold, Rates, and the Spousal Portability Trap

Rhode Island is one of only 12 states (plus DC) that still imposes its own estate tax, separate from the federal estate tax. And its exemption threshold is dramatically lower than the federal one — low enough that many middle-class homeowners with a 401(k) can cross it without realizing it.

2026 Threshold: $1,838,056

For decedents dying on or after January 1, 2026, the Rhode Island estate tax exemption is $1,838,056, with an associated estate tax credit of $87,940. This threshold is adjusted annually based on the Consumer Price Index for all Urban Consumers (CPI-U).

For context, here's how the threshold has moved in recent years:

Compare this to the federal estate tax exemption of $15 million in 2026. A Rhode Island family with a $2 million estate pays nothing in federal estate tax but faces a state estate tax bill with rates reaching up to 16%.

The Spousal Portability Trap

This is the single biggest estate tax planning mistake Rhode Island families make. Under federal law, the estate tax exemption is fully portable between spouses. If one spouse dies and doesn't use their full $15 million federal exemption, the surviving spouse can inherit the unused portion — protecting up to $30 million for a married couple.

Rhode Island's exemption is not portable. When the first spouse dies and leaves everything to the surviving spouse using the unlimited marital deduction, the deceased spouse's $1,838,056 state exemption is permanently lost. When the surviving spouse later dies, only a single exemption of $1,838,056 can be applied.

For a couple with combined assets of $3 million — a modest home, retirement accounts, and life insurance — this means roughly $1.16 million is exposed to Rhode Island estate tax at the second death, instead of zero with proper planning.

How a Credit-Shelter Trust Solves This

The standard solution is a credit-shelter trust (also called a bypass trust or B trust). When the first spouse dies, instead of leaving everything outright to the survivor, assets up to the state exemption amount ($1,838,056) are placed in an irrevocable trust. The surviving spouse can draw income from the trust and even access principal for health, education, maintenance, and support — but the trust assets are not counted as part of the surviving spouse's estate.

Result: each spouse's exemption is captured, sheltering up to $3.67 million from Rhode Island estate tax instead of $1.84 million.

This planning requires a financial power of attorney with explicit trust management authority — one of the "hot powers" that must be specifically granted under Rhode Island common law.

Filing Requirements: Everyone Must File

Here's another trap: even if the estate is below the $1,838,056 threshold and owes zero tax, the executor must still file Form RI-706 (Rhode Island Estate Tax Return) with the Division of Taxation if the estate includes any real property.

Why? Rhode Island imposes an automatic statutory lien under RIGL § 44-23-12 on all real estate owned by a decedent at death. This lien clouds the title and prevents any sale, transfer, or refinancing until the Division of Taxation issues a formal discharge.

Filing requirements by estate size:

• Gross estates under $1.3 million: Complete only pages 1-4 of Form RI-706, including the high-level Recapitulation Schedule. Detailed individual asset schedules are waived.
• Gross estates $1.3 million and above: Complete the full Form RI-706 with every individual asset schedule.

Good news: the $50 filing fee for Form RI-706 was eliminated for decedents dying on or after January 1, 2025. There's now no charge to file.

Practical Planning Steps

1. Calculate your exposure. Add up your home's current market value, retirement accounts, life insurance death benefits, investment accounts, and business interests. If the total exceeds $1.84 million (or could by the time of your death), you need planning.

2. Set up a durable financial POA with explicit authority to manage trust assets, change beneficiary designations, and handle estate tax filings. These are "hot powers" that must be specifically drafted — they don't come automatically with a general POA.

3. Consult a CPA for precise calculations. The interplay between the state estate tax, the automatic real estate lien, and credit-shelter trust funding requires professional guidance.

4. Re-execute your POA regularly. A financial institution managing trust assets is even more likely to reject a "stale" POA than one managing a simple checking account.
