3-year gift lookback in Oregon
Oregon adds back taxable gifts made within 3 years of death when computing the taxable estate. Gifting assets to reduce the estate can fail if death occurs too soon — plan for the lookback window, not just the exemption.
This mirrors the federal 3-year lookback concept (IRC § 2035) for gift tax paid, but Oregon's rule applies to the gifts themselves. Confirm the current statute.
Administration & filing in Oregon
- Who pays: The estate pays the tax before distribution to heirs.
- Where filed: With Oregon's tax authority (typically the Department of Revenue or Taxation), on a state estate/inheritance tax return.
- Deadline: State returns generally follow the federal estate tax return timeline (IRS Form 706, due ~9 months after death, with a 6-month extension available), but state dates can differ — confirm with the state agency.
