Quick answer: yes — an estate can owe zero federal estate tax and still owe real money to Rhode Island, because the state threshold sits at less than an eighth of the federal line. Run your own numbers in the Rhode Island estate tax calculator.
Two thresholds, far apart
The federal estate tax exemption sits at roughly $15,000,000 per individual for 2026. Rhode Island's own threshold is $1,838,056 — less than an eighth of the federal line. Any estate between those two numbers owes nothing federally but can face a genuine Rhode Island tax bill computed under the state's own formula.

Ordinary Rhode Island homeowners cross this line
A paid-off home, a retirement account, and modest savings can add up past $1,838,056 well before an estate ever comes close to the federal exemption — a genuinely common situation for Rhode Island families who assume "no federal tax" means no death tax exposure at all.
A local probate attorney can review your estate — many offer a free consultation.
