Washington Senate Democrats are advancing a bill to reverse the state’s recent estate tax increases, a move that directly challenges the logic of the federal GOP’s decision to permanently raise the estate tax exemption to $15 million. The effort, carried out through SB 6347, has drawn little public attention despite clearing a key committee vote, partly because it was scheduled alongside a higher-profile millionaires’ tax proposal. The bill’s quiet progress reflects a growing tension between state and federal approaches to taxing inherited wealth, and it could signal how blue states plan to respond to what critics call a federal giveaway to the ultra-wealthy.
A Federal Windfall Meets State-Level Pushback
The federal estate tax picture shifted dramatically when Congress passed the One Big Beautiful Bill Act, formally known as P.L. 119-21. Section 70106 of that law increased the base estate, gift, and generation-skipping transfer tax exemption to $15 million in 2026, up from a base amount of $5 million that had been inflation-adjusted under prior law. The Congressional Research Service noted the pre-2026 exemption stood at $13.99 million for 2025, meaning the new threshold represents a significant jump that benefits only the wealthiest estates. The federal estate and gift tax rate itself remains at 40%, but the higher exemption ensures far fewer estates ever reach that rate. Some GOP members pushed even further. H.R. 1301, titled the so-called Death Tax Repeal Act, proposed eliminating the estate and generation-skipping transfer taxes entirely, as reflected in the text of that repeal bill. That measure did not make it into the final reconciliation package, but its existence reveals the political pressure that shaped the exemption increase as a compromise position rather than a ceiling.
Washington state moved in the opposite direction. Legislation effective July 1, 2025, restructured the state’s estate tax with rates ranging from 10% to 35%, including a top marginal bracket of 35% on taxable amounts above $9 million, according to the state’s published estate tax tables. The state’s estate tax exclusion sits at $3,000,000, far below the federal threshold. This creates an unusual dynamic: a wealthy Washington resident’s estate could owe nothing to the IRS under the new federal exemption while still facing a steep state bill. That gap is precisely what SB 6347’s sponsors appear to be targeting, though no public fiscal impact statements or sponsor floor remarks are available to confirm the precise revenue trade-offs they envision. The contrast underscores how federal changes can magnify the political stakes of state-level tax design, especially in high-wealth, high-cost jurisdictions that already rely heavily on progressive revenue sources.
SB 6347’s Quiet Path Through Committee
The bill, formally titled “Undoing the recent changes to the estate tax,” was reported out of the Senate Ways and Means Committee on February 9, 2026, after a public hearing three days earlier. Its sponsors include Democratic Senators Kauffman, Slatter, Dhingra, and Liias. The February 6 hearing placed SB 6347 on the same committee agenda as SB 6346, a separate proposal addressing a millionaires’ tax. That pairing meant the estate tax rollback received less individual scrutiny from media and advocacy groups focused on the flashier revenue measure. No verbatim testimony transcripts from the hearing have been published, leaving the public record thin on what arguments supporters and opponents made during the session, and making it harder for voters to assess how lawmakers weighed the competing goals of fairness and fiscal stability.
The lack of available testimony or detailed fiscal notes is itself telling. Without official projections on how much revenue the rollback would forgo, or which segments of the population would benefit most, the debate risks being conducted largely behind closed doors. Washington’s legislative website, hosted at the main state Legislature portal, lists the bill’s status and sponsors but does not yet provide a full fiscal analysis comparable to those attached to other major tax measures. That omission may be temporary, but for now it reinforces the sense that SB 6347 is moving under the radar even as it touches a core element of the state’s progressive tax structure. For a policy area as politically charged as taxing large inheritances, the combination of a low public profile and incomplete documentation stands in contrast to the sweeping federal shifts that helped trigger the state-level response.
