As of June 4, 2025, the Oregon Legislature is actively considering multiple bills aimed at reforming the state's estate tax, which currently has the nation's lowest exemption threshold at $1 million and a top rate of 16%. These proposals seek to modernize the tax structure, reduce its burden on families and small businesses, and address concerns about taxpayer outmigration.taxfoundation.org+1commonsenseinstituteus.org+1

Key Legislative Proposals

  1. SB 485Forestland Estate Tax Exemption Reform
    This bill revises the estate tax exemption criteria for small forestland owners. It adjusts management requirements to better reflect forestry practices, moving away from rigid participation thresholds. The Senate unanimously passed SB 485 on May 20, and a public hearing was scheduled in the House Revenue Committee on June 4.
  2. HB 2058Aligning with Federal Exemption
    Proposes increasing Oregon's estate tax exemption to match the federal level of $13.99 million for decedents dying on or after January 1, 2026. This change would significantly reduce the number of estates subject to the tax.
  3. SB 405 and SB 648Federal Conformity Measures
    Both bills aim to raise the estate tax exemption to $13.61 million, aligning with the federal basic exclusion amount. SB 648 has undergone a public hearing in the Senate Finance and Revenue Committee.
  4. HB 2301Flat Tax Rate Introduction
    Suggests replacing the current progressive estate tax rates with a flat 7% rate and increasing the exemption to $7 million. This approach seeks to simplify the tax system and reduce administrative complexity.
  5. HB 3737Inflation-Adjusted Exemption
    Proposes raising the exemption to $4 million and indexing it for inflation, ensuring the threshold remains relevant over time.
  6. HB 2112 and HB 2362Graduated Exemption Models
    These bills introduce a sliding scale for exemptions, ranging from $1.5 million to $0, depending on the estate's value. This model aims to provide relief to smaller estates while maintaining revenue from larger ones.

Our Take: SB 485 would not impact most Oregonians. SBs 2058, 405, and 468 have zero chance of being passed as they would create a huge hole in Oregon's budget. SBs 648, 3737, 2112, and 2362 are serious proposals worthy of further discussion and debate.
