Oregon and Washington, weighed as two operating environments.
Not which state is better — the wrong question. This instrument weighs both environments
on the same five decision lenses and shows which coordination priorities change when the
environment does. Same reasoning every state is read through; here, side by side.
Each lens turns a tax environment into a household decision.
A dashed row means the two environments read the same on that lens; a solid row means they differ.
high
Rate pressureHow much does the state erode each realized gain?
high
OregonThe state takes 9.9% of every long-term gain at the top — high drag on what a realized return keeps.
WashingtonThe state takes 9.9% of every long-term gain at the top — high drag on what a realized return keeps.
severe
Estate exposureDoes the state tax the estate below the federal threshold, and how steeply?
severe
OregonA state estate tax exempts only $1M — far below the federal ~$14M; severe exposure at death that federal-only planning misses.
WashingtonA state estate tax exempts only $3M — far below the federal ~$14M; severe exposure at death that federal-only planning misses.
high
Harvesting leverageHow much is a harvested loss worth here?
high
OregonA harvested loss is worth the 9.9% state rate it offsets, on top of federal — high harvesting leverage.
WashingtonA harvested loss is worth the 9.9% state rate it offsets, on top of federal — high harvesting leverage.
high
Mobility valueHow much could a change of residency be worth?
high
OregonBoth the rate and the estate regime make relocation genuinely valuable — but domicile is a fact pattern, not a mailing address.
WashingtonBoth the rate and the estate regime make relocation genuinely valuable — but domicile is a fact pattern, not a mailing address.
low
Basis coordinationWhat basis-step-up opportunity does the marital-property regime create?
high
OregonAdopted the UDCPRDA — community-property basis treatment can be imported by trust for couples who plan for it.
WashingtonCommunity-property state: community assets get a FULL step-up at the first death — title them so the survivor keeps that basis.

Shared
Residency & domicile· advisor + CPA
Whether — and how — a change of domicile is worth pursuing, and the facts (days, home, ties) that make it real rather than nominal.
Estate structure· estate attorney
Whether the state's estate exposure warrants credit-shelter / QTIP titling or lifetime gifting to move value below the state threshold.
Loss harvesting· advisor + CPA
Setting a harvesting cadence that captures the state rate a banked loss offsets, sequenced against the state's loss-carryforward rules.
Asset location· advisor
Placing the high-turnover sleeve in tax-advantaged accounts so the state's rate falls on the least of the household's realized gains.
Only Washington
Asset titling for step-up· estate attorney
Titling assets to capture the fullest basis step-up the marital-property regime allows at the first death.
The facts underneath
Dimension

Washington
Capital-gains rate
9.9%Loss treatment conforms to federal: capital losses net against gains and carry forward. Top effective long-term rate 9.9%. Quirk: + Portland-metro tax up to 4% (~13.9% combined).
9.9%Taxes long-term gains only — a 7% + 2.9% excise on long-term gains only, gross of short-term losses. Top effective long-term rate 9.9%.
Basis step-up
UDCPRDACommon-law state that has adopted the UDCPRDA — it preserves the community-property character (and the potential full step-up) of assets a couple brought from a CP state.
CPCommunity-property state: BOTH halves of community property step up to fair market value at the first spouse's death (IRC 1014(b)(6)) — a major basis advantage.
Marriage treatment
2xJoint brackets are double the single brackets — generally marriage-neutral.
1xOne bracket schedule applies to both single and joint filers — a structural marriage penalty for two earners.
Municipal bonds
in-stateOnly in-state municipal-bond interest escapes state tax; bonds from other states are taxed. The classic in-state muni preference that rewards a home-state ladder.
exemptMunicipal-bond interest is exempt from state tax whether the issuer is in-state or out-of-state — the broadest muni preference (states with no tax on investment income, plus a few that exempt all munis by statute).
Illustrative coordination gap
Because the rules differ, so does what coordination is worth. On an illustrative 30-year path, running a portfolio against each state's rules is worth an estimated ~$44,000/yr per $1M taxable in Oregon versus ~$33,000/yr in Washington — the coordination gap between the two (about +4.4%/yr vs +3.3%/yr modeled). A hypothetical, illustrative figure; the household's own depends on bracket, holdings, and residency (see the full basis of the estimate below).
A difference between two states is a decision waiting to be coordinated.
Turn it into a sequenced operating plan for a move, or fold it into a household's standing coordination record.

Illustrative / hypothetical — not a real track record and not advice. The tax-management impact figure is a hypothetical, after-tax result from the retroactive application of a tax-management model to ~30 years of proxy-spliced market data on a single illustrative path; no client capital was invested, and hypothetical performance does not guarantee future results. Intended for sophisticated investors; it may not be relevant to your situation, and your actual figure depends on your own holdings, basis, and bracket.
