Rhode Island Estate Tax in 2026: Exemption, Rates & Calculator
Rhode Island's exemption is modest — $1,838,056 for 2026 — and, like Massachusetts, the actual tax calculation runs through a decades-old federal credit table rather than a simple bracket lookup. Both the exemption and the credit amount adjust every year for inflation.
Calculate Rhode Island estate tax for your situationHow Rhode Island taxes an estate
Rhode Island computes a tentative credit using the same frozen pre-2001 federal 'state death tax credit' table Massachusetts uses, applied to the taxable estate minus $60,000, then subtracts an annually CPI-adjusted credit amount ($87,940 for 2026). Because of that credit-table structure, there's no single flat rate to quote — this page shows a worked example instead of a bracket table.
Worked example
A $10,000,000 Rhode Island taxable estate produces a tentative credit-table amount of $1,067,600; subtracting the 2026 credit amount of $87,940 leaves $979,660 owed.
Rules worth knowing
- Both the $1,838,056 exemption threshold and the $87,940 credit amount are re-published by the Rhode Island Division of Taxation every year, compounded by CPI-U and rounded to the nearest $5 — always double-check the current year's figures rather than reusing last year's.
- The 2025 figures ($1,802,431 exemption / $85,375 credit) are lower than 2026's — using a prior year's numbers for a 2026 estimate would understate the exemption.
Filing deadline
The federal Form 706 return, when required, is due 9 months after the date of death (IRC §6075(a)). Rhode Island's own Form RI-706 has its own deadline — confirm the exact requirement with the Rhode Island Division of Taxation rather than relying on the federal date.
