Washington Retirement Income Tax 2026: $0 on IRAs and RMDs

Washington is one of nine states with no income tax — which means IRA withdrawals, 401(k) distributions, required minimum distributions, pensions, and Social Security are all free of state income tax. For a retired couple taking $150,000 in annual RMDs, that's $11,000 less in state income tax than they'd pay in Oregon, and $6,300 less than in California. But two planning traps catch Washington retirees off guard: a 7%–9.9% capital gains excise tax on investment gains in taxable accounts (not retirement accounts), and a state estate tax that starts at $3 million — far below the federal $15 million exemption under the One Big Beautiful Bill Act. A third change is coming: a 9.9% income tax on income above $1 million takes effect January 1, 2028 (ESSB 6346). For most retirees, Washington remains highly favorable. For those with large estates or significant taxable-account gains, the planning nuances matter.

Washington retirement income tax rules — 2026 summary:

IRA withdrawals, 401(k), 403(b), RMDs: $0 Washington state tax. Washington has no personal income tax. All ordinary income from retirement accounts is exempt.¹
Social Security: $0 Washington state tax. All Social Security income is exempt — no phase-in, no income limit, no age requirement.¹
Pensions and annuities: $0 Washington state tax. Private pensions, government pensions (PERS, military, federal), and annuity income are all exempt from Washington income tax.¹
Long-term capital gains (taxable accounts): 7% on net gains above $278,000 (2025 confirmed; 2026 threshold pending WA DOR publication, typically a modest inflation adjustment). An additional 2.9% applies to taxable gains above $1 million (total rate: 9.9%). This tax does NOT apply to IRA, 401(k), or RMD distributions — those are ordinary income, not capital gains.²
Roth IRA distributions: $0 Washington tax. Roth distributions are excluded from federal AGI and are not capital gains for WA excise tax purposes.
Washington estate tax: Applies on estates above $3,000,000 (ESB 6347, effective July 1, 2026) at rates of 10%–20%. No portability between spouses. Far below the federal $15M OBBBA exemption.³
Property tax: ~0.84% average effective rate statewide. Senior exemption programs available (income-tested, varies by county). King County (Seattle area) runs higher; eastern Washington is lower.⁴
Sales tax: 6.5% state base rate + local additions (Seattle: ~10.25%). Unlike Oregon, Washington has a sales tax — offset by the $0 income tax and no estate tax below $3M.¹
Income tax coming 2028: ESSB 6346 (signed March 30, 2026) creates a 9.9% income tax on income above $1 million per taxpayer, effective January 1, 2028. For retirees with RMDs under $1 million annually, this does not apply.⁵

Washington vs. Oregon and California: the income tax comparison

For retirees whose income comes primarily from traditional IRA distributions, RMDs, Social Security, and pensions, Washington is dramatically cheaper than its Pacific Coast neighbors. The comparison uses the same retirement income profile: married couple, both 65+, income from RMDs only (no Social Security, to isolate state tax treatment).

Annual RMD (MFJ, both 65+, no SS)	Washington state tax	Oregon state tax	California state tax
$80,000	$0	~$5,651	~$1,588
$150,000	$0	~$11,002	~$6,288
$250,000	$0	~$19,594	~$16,550
$400,000	$0	~$40,079	~$33,290

Oregon: starts from federal AGI; applies SS exemption, federal tax paid deduction (capped at $14,100 MFJ), and $5,495 standard deduction. California: CA standard deduction $10,404 MFJ; no retirement income exemption. Washington: $0 income tax on ordinary income. Federal income tax is identical in all three states at the same income level. Neither the WA capital gains tax nor WA estate tax applies to these RMD-only scenarios.

Washington capital gains excise tax: what it does and doesn't cover

Washington's capital gains excise tax (enacted 2021, upheld by the Washington Supreme Court March 2023) applies to long-term capital gains realized in taxable brokerage accounts. It does not apply to IRA or 401(k) distributions — those are ordinary income, not capital gains for purposes of this tax.²

What the WA capital gains tax covers (and doesn't):

Covered: Long-term gains on stocks, bonds, mutual funds, ETFs sold in taxable brokerage accounts. Business sale proceeds (unless qualified small business exception). NUA gains on employer stock distributed from 401(k) — the NUA component is a capital gain even though the distribution originated from a retirement plan.
Not covered (IRA/retirement distributions): IRA withdrawals, 401(k) distributions, 403(b), 457(b), TSP, RMDs, Roth IRA distributions, pension income, annuity payments. These are ordinary income — not capital gains — and are fully exempt from both the WA capital gains tax and Washington's income tax.
Not covered (real estate): Gains on sales of real property (real estate is specifically excluded from the WA capital gains excise tax base).
Not covered (retirement accounts): Gains inside an IRA or 401(k) compound tax-deferred and are never subject to WA capital gains tax — they're taxed as ordinary income upon distribution, and Washington has no income tax.

The practical implication: retirees whose wealth is primarily in traditional IRAs and 401(k)s — which describes most of this site's audience — have no Washington state tax exposure whatsoever on their retirement distributions. The capital gains tax only matters if you also hold a taxable brokerage account with significant unrealized gains that you plan to realize.

Washington estate tax: the $3 million trap for large-IRA holders

Washington imposes a separate estate tax that applies long before the federal estate tax — and long before most retirees expect. Under ESB 6347 (signed March 2026, effective July 1, 2026), the Washington estate tax exemption is $3,000,000 per person, with rates ranging from 10% to 20% on the taxable estate above that amount.³

For perspective: the federal estate tax exemption under the One Big Beautiful Bill Act (OBBBA, July 2025) is $15 million per person — five times Washington's threshold. A retiree who dies with a $5 million estate owes zero federal estate tax but owes Washington estate tax on $2 million ($5M − $3M exemption). At graduated rates, that's approximately $200,000–$250,000 in Washington estate tax — paid before heirs receive anything.

Washington estate tax key rules (post-July 1, 2026):

Exemption per person: $3,000,000 (ESB 6347). Beginning 2027, this amount will be inflation-adjusted using the CPI. For deaths January 1–June 30, 2026, the exemption was $3,076,000 (pre-ESB 6347 amount).
No portability between spouses. Unlike federal law, Washington does not allow a surviving spouse to use the deceased spouse's unused exemption (DSUEA). Each spouse has one $3M exemption — with no ability to "stack" them as the federal system allows. A couple with a $10M estate effectively has $6M exempt and $4M subject to WA estate tax, not $10M exempt as they might expect federally.
Rate schedule: 10% on the first $1M above the exemption, scaling through 14 brackets to 20% on the amount above approximately $9 million. The effective rates for common estate sizes: ~12%–14% for estates $4M–$7M.
Traditional IRA problem: IRA balances are included in the taxable estate — but heirs also pay income tax on distributions (no step-up in basis). A $3M traditional IRA faces both WA estate tax and income tax as heirs distribute it. See the IRA estate planning guide for strategies.
No marital deduction strategy nuance: Assets left to a surviving spouse qualify for an unlimited marital deduction and defer the Washington estate tax until the second death. But on the second death, the surviving spouse has only one $3M exemption — not $6M. Proper estate planning uses trusts or other structures to maximize both exemptions.

WA estate tax worked example: $8M estate, two-spouse scenario

Scenario	Taxable estate	WA estate tax (approx.)	Federal estate tax
$4M estate, one person (all assets)	$4M − $3M = $1M taxable	~$100,000 (10% first bracket)	$0 (below $15M OBBBA)
$8M estate, surviving spouse (second death)	$8M − $3M = $5M taxable	~$700,000–$750,000	$0 (below $15M OBBBA)
$8M estate, same in Oregon	$8M − $1M = $7M taxable	~$980,000–$1,050,000 (OR)	$0 (below $15M OBBBA)

Washington is significantly better than Oregon on estate tax ($3M vs. $1M exemption, and OR rates up to 16%). But it is still material for large-IRA holders who expect zero state estate tax because of the federal OBBBA exemption.

The Washington estate tax creates a compelling reason to execute Roth conversions during the pre-RMD window. Every $100,000 converted from traditional to Roth IRA reduces the traditional IRA balance — which flows into the taxable estate — by $100,000. The Roth IRA is still in the estate for WA estate tax purposes, but the income tax liability embedded in the traditional IRA is gone. The effective estate value of Roth vs. traditional IRA dollars is not equal: a traditional IRA includes deferred income taxes as an "encumbrance" that reduces the real economic value to heirs even if not deducted from the gross estate for estate tax purposes.

Roth conversion advantage: $0 Washington state tax on conversions

Washington's $0 income tax creates one of the most powerful Roth conversion environments in the country. Other Pacific Coast states extract significant state income tax on every dollar converted:

State of residence during conversion	Marginal state rate on $100K conversion	State tax on $100,000 Roth conversion
Washington	0%	$0
Oregon	8.75%–9.9%	$8,750–$9,900
California	9.3%–13.3%	$9,300–$13,300
New York	6.85%–10.9%	$6,850–$10,900
Colorado	4.4%	$4,400
Arizona	2.5%	$2,500

State income tax only; federal tax applies in all states. Rates shown for common RMD + conversion income levels.

A Washington couple who converts $500,000 during the ages-60-72 pre-RMD window pays zero Washington state tax on that $500,000 — compared to $43,750–$49,500 in Oregon state tax, or $46,500–$66,500 in California. Use the Roth conversion calculator to model the federal + state break-even timeline from a Washington starting point.

Washington residents also benefit from the federal side: the Roth conversion window (ages 62–72) is typically the period with the lowest marginal income since earned income has stopped but Social Security and RMDs haven't started yet. Washington retirees in this window pay federal tax only — the most favorable combination of state + federal rates available in the U.S. for large Roth conversions.

Washington income tax coming in 2028: planning context for high-income retirees

ESSB 6346 (signed March 30, 2026 by Governor Ferguson) creates a 9.9% income tax on Washington residents with income above $1 million per year, effective January 1, 2028.⁵ Key planning context:

Who it affects: Retirees with total income (RMDs + SS + pension + investment income + capital gains) exceeding $1 million annually. For most retirees, this threshold is not reached — even a $10 million IRA at age 80 generates approximately $750,000–$850,000 in RMDs using the Uniform Lifetime Table divisors, below the $1M threshold.
Threshold is per taxpayer, not per couple. A $1 million-per-person threshold means a MFJ couple would need $2 million in combined income (if filing separately) — or $1 million total (if the threshold applies to joint income). The legislation specifies $1 million per taxpayer; married-filing-jointly rules are subject to regulatory guidance.
Constitutional uncertainty. Washington's constitution has historically been interpreted as prohibiting income taxes on individuals. The capital gains excise tax survived legal challenge by being classified as an "excise tax" rather than an "income tax." The millionaires income tax faces similar but more direct constitutional questions. Its eventual implementation is not guaranteed.
Planning implication: For retirees near the $1M income threshold, accelerating Roth conversions before 2028 reduces future RMD income below the threshold and locks in $0 state tax permanently on the Roth balances. See the Roth conversion sizing calculator.
For most retirees: This does not apply. Washington remains a $0 income tax state for income under $1 million, with no current change to that status for 2026 or 2027.

Vancouver, Washington: the Pacific Northwest tax arbitrage

Vancouver, Washington sits directly across the Columbia River from Portland, Oregon. Moving from Portland (or the broader Portland metro area) to Vancouver provides full Washington state income tax advantages while retaining access to Oregon's sales-tax-free retail shopping — creating one of the most efficient geographic tax arbitrages for retirees.

Tax type	Portland, Oregon	Vancouver, Washington
State income tax on $150K RMDs (MFJ)	~$11,002/year	$0
State income tax on $100K Roth conversion	~$8,750–$9,900	$0
Long-term capital gains (state rate)	8.75%–9.9%	0% on IRAs; 7%–9.9% on taxable gains over $278K
Estate tax exemption	$1,000,000 at 10%–16%	$3,000,000 at 10%–20%
State sales tax	None	~8.4% (Clark County) — but Oregon stores 10 min away
Property tax (avg effective rate)	~0.90–0.95%	~0.85% (Clark County)

The sales tax offset is real but bounded. Most retirees buy discretionary goods — cars, electronics, appliances — in Portland (Oregon sales tax: zero) while living in Vancouver. Grocery and restaurant spending in Vancouver carries WA sales tax, but discretionary purchases are strategically placed in Oregon. The annual income tax savings ($11,000–$40,000 at common RMD levels) typically exceed any sales tax cost differential for retirees who establish a Vancouver domicile.

Estate tax advantage is compelling for larger estates: Oregon's $1 million threshold vs. Washington's $3 million threshold means a $2.5 million estate that faces Oregon estate tax faces none in Washington. See the retirement tax relocation guide for domicile change process.

Washington domicile: establishing residency for income tax purposes

Because Washington has no income tax, the Washington Department of Revenue does not audit former residents attempting to establish Washington domicile the way California (FTB 936-day rule) and New York (183-day statutory residency trap) do. But Oregon's Department of Revenue is its own enforcement entity — if you're moving from Oregon, you need to cleanly sever Oregon domicile.

Washington driver's license. Obtain within 30 days of establishing Washington residency (RCW 46.20.342). This is the primary domicile signal.
Vehicle registration. Register in Washington within 30 days. Surrender Oregon plates.
Voter registration. Register at Washington address. Cancel Oregon registration proactively if automatic deregistration is delayed.
Update financial accounts. IRA custodians, banks, brokerage firms, pension payers — all should receive new Washington address. Oregon PERS/OPSRP members: notify PERS of address change immediately (pension income during Oregon-resident period is still Oregon-taxable; post-move payments are Washington-tax-free).
File part-year Oregon return. Oregon taxes income earned during your Oregon residency period, including IRA distributions taken before the move date. After the move date, Oregon cannot tax your income. File Form OR-40-P for the year of the move.
Roth conversion timing: Every dollar converted after establishing Washington domicile saves 8.75%–9.9% in Oregon state income tax. For Oregon retirees planning a move, sequence the conversion after the move, not before.

Connect with a fee-only RMD advisor for Washington state retirees

Washington's $0 income tax on retirement distributions is a significant advantage — but optimizing around the capital gains tax, the $3M estate tax threshold, and the Roth conversion window requires integrated planning. A fee-only RMD specialist models the federal + state stack together: which assets to hold in taxable vs. Roth vs. traditional, how to sequence Roth conversions to minimize future RMDs below IRMAA thresholds and the 2028 income tax threshold, and how to structure beneficiary designations to manage Washington estate tax exposure.
