Washington State LGBTQ+ Financial Planning Guide 2026

This guide covers financial planning issues specific to LGBTQ+ households in Washington state — community property for registered domestic partners, the $3M estate tax trap with no portability, Washington's two-tier capital gains tax, and WA PFML's coverage of domestic partners. Not legal or tax advice — your specific situation requires qualified professionals.

Washington is one of the most protective states for LGBTQ+ households in the country. Same-sex marriages are fully recognized, the Washington State Registered Domestic Partnership (RDP) program extends state community property rights and most marital benefits to qualifying partners, and the Washington Paid Family and Medical Leave program explicitly covers registered domestic partners on the same terms as spouses. Seattle has one of the highest concentrations of LGBTQ+ households in the US. But Washington's financial planning landscape has features that catch even well-prepared households off guard: a $3 million estate tax exemption with no portability (far lower than the federal $15 million), a unique capital gains tax with 7% and 9.9% tiers that applies to investment gains above roughly $262,000, and a community property regime that creates both a powerful estate planning tool and a mandatory federal tax filing obligation. Understanding exactly where Washington law helps and where it creates traps is essential for LGBTQ+ financial planning here.

1. Washington Legal Landscape: Marriage, RDP, and the 62+ Rule

Washington state has three LGBTQ+-relevant legal statuses with meaningfully different financial implications:

Legal marriage (same-sex, effective December 6, 2012)

Washington became the seventh state to legalize same-sex marriage when voters approved Referendum 74, effective December 6, 2012. Married same-sex couples in Washington have full state and federal marriage rights: joint federal and state tax returns, Social Security spousal and survivor benefits, federal FMLA, ERISA retirement account spousal protections, the unlimited federal marital deduction, and full community property treatment under Washington law. The marriage date runs from December 6, 2012, at the earliest for the Social Security 1-year spousal benefit clock and 10-year divorced-spouse clock.

Washington State Registered Domestic Partnership (RDP)

Washington's RDP program (RCW 26.60) was originally created for same-sex couples and senior opposite-sex couples in 2007, then substantially expanded by the Everything But Marriage Act in 2009. Under Washington law, registered domestic partners receive all the same legal rights and responsibilities as married spouses — including community property treatment, inheritance rights, hospital visitation, healthcare proxy authority, state PFML coverage, and state employee benefits.¹

Current eligibility (as of June 2026): To register a new Washington RDP today, at least one partner must be 62 years of age or older. The age requirement exists because the original purpose of senior-couple RDPs was to allow cohabiting seniors to obtain legal protections without losing widow(er) Social Security benefits or pension survivor benefits tied to not remarrying — a calculation that still applies for many 62+ individuals. Younger same-sex couples whose RDPs were automatically converted to marriages in 2014 are now legally married. New laws effective June 11, 2026, affect the registration process — check the Washington Secretary of State's office for current procedures.²

Unregistered domestic partnership

Younger LGBTQ+ couples (both partners under 62) who are not legally married and not eligible for a new RDP registration are in the same position as unregistered domestic partners in most other states: no community property treatment, no WA PFML spousal coverage, no ERISA §205 spousal protection, no Social Security spousal or survivor benefits. Washington has no statewide DP registry for younger couples. The five-document estate plan (financial DPOA, healthcare proxy, HIPAA authorization, advance directive, hospital visitation authorization) is essential. See our LGBTQ+ Powers of Attorney and Healthcare Proxy guide.

2. Community Property: The 100% Basis Step-Up and the Form 8958 Obligation

Washington is one of nine community property states. For married same-sex couples and registered domestic partners, this creates both a powerful estate planning tool and a mandatory federal tax filing obligation.

The 100% basis step-up at death

In community property states, both halves of a community asset receive a full basis step-up when one spouse/partner dies — not just the decedent's half. In common-law states like Illinois or Florida, only the decedent's proportionate share gets stepped up; the survivor's half retains its original cost basis.

Example: a Washington married same-sex couple bought stock in 2010 for $100,000 that is now worth $1,000,000. If one spouse dies, the surviving spouse's entire $1,000,000 basis is stepped up to $1,000,000 — eliminating $900,000 of embedded capital gain entirely. In Illinois, the survivor would retain $450,000 of their original basis and owe capital gains tax on $450,000 of appreciation if they later sold.

For LGBTQ+ households with significant long-held investment portfolios, brokerage accounts, or appreciated real estate, the community property step-up is worth a substantial amount in avoided capital gains taxes — potentially hundreds of thousands of dollars. This benefit applies to both married same-sex couples and state registered domestic partners under Washington law.³

The Form 8958 filing obligation for RDPs

Here is the catch: Washington state treats registered domestic partners as spouses for community property purposes. But the federal government does not recognize the RDP relationship. This creates a specific IRS filing requirement: registered domestic partners in Washington must file federal Form 8958 (Allocation of Tax Amounts Between Certain Individuals in Community Property States) each year to split their community income between their individual federal returns.⁴

Under Washington community property law, wages earned by either partner during the RDP are community income — 50% attributable to each partner. If Partner A earns $200,000 and Partner B earns $50,000, each reports $125,000 of community wage income on their individual federal returns, not $200,000 and $50,000. The allocation also affects investment income on community assets. Form 8958 is filed with each partner's individual federal return (no joint return is available for RDPs). Failure to file Form 8958 when required is a reporting error that can trigger IRS correspondence even when the total tax owed is correct.

Community property and the WA capital gains tax (7%/9.9%)

Washington's capital gains tax applies to each taxpayer's individual net long-term capital gains above the annual deduction (~$262,000 in 2026). For married couples filing jointly on their WA return, gains are combined. For RDPs, the community property split applies: gains on community assets are each 50% attributable to each partner for both federal and WA purposes, which effectively doubles the threshold — each partner has their own ~$262,000 deduction. See Section 5 for details on the capital gains tax.

3. Washington Estate Tax: $3M Exemption, No Portability

Washington's estate tax is the most consequential state-specific planning issue for LGBTQ+ households with combined wealth above $3 million. It has two features that directly harm LGBTQ+ households: a much lower exemption than the federal threshold and no portability between spouses or RDP partners.

The $3 million threshold — and the 2026 rate rollback

Washington imposes an estate tax on estates exceeding $3,000,000 per individual (for deaths on or after July 1, 2026, following Governor Ferguson signing Engrossed Senate Bill 6347, which rolled back the 2025 rate increase and reset the exemption). For deaths between January 1 and June 30, 2026, the threshold is $3,076,000.⁵

Compare: the federal estate exemption is $15,000,000 (permanently raised by OBBBA, July 2025). The Washington exemption is 80% lower. For Seattle-area LGBTQ+ households — where a modest home, two retirement accounts, and some brokerage savings can add up quickly — the $3M threshold is not hypothetical. A couple with a $900,000 home, $1.5M in combined 401(k)s, $400K in brokerage, and $200K in life insurance is already near the per-person threshold.

Washington estate tax rates (effective July 1, 2026)

Rates return to pre-July 2025 levels, with a top marginal rate of 20% for estates above approximately $9M. The rates are graduated using a credit table:

No portability — the WA planning gap

Federal estate tax law allows portability: the surviving spouse can elect to use the deceased spouse's unused federal exemption (DSUE). Washington does not allow portability. If Spouse A dies with a $2M estate, their unused $1M of the $3M Washington exemption is permanently lost — it cannot be carried to Spouse B's estate. When Spouse B dies with a $6M estate, Washington taxes the $3M excess even though Spouse A's exemption was entirely wasted.

This no-portability rule applies equally to registered domestic partners who receive the WA marital deduction — assets pass to the surviving RDP partner without triggering WA estate tax at the first death, but the no-portability rule means the survivor's eventual estate faces WA estate tax on all amounts above their own $3M exemption.

For couples with combined estates between $3M and $6M, the no-portability rule can cost $100,000–$300,000 in unnecessary Washington estate tax without proper planning.

Washington marital deduction applies to RDPs

Under RCW 26.60, registered domestic partners receive all the same legal rights as married spouses under state law, including the Washington unlimited marital deduction for estate tax purposes. Property passing from one RDP partner to the other at death is not subject to Washington estate tax at the first death — but as noted above, the no-portability trap still applies at the survivor's eventual death.

Credit shelter trust (bypass trust) to recover both exemptions

The standard planning response to Washington's no-portability rule is a credit shelter trust (bypass trust). The first-to-die funds a trust with assets up to their $3M WA exemption. The trust assets are designed to be outside the surviving partner's taxable estate — the survivor receives income and limited HEMS access but does not own the trust assets outright. When the survivor dies, the trust assets pass to final heirs outside the estate, having been sheltered by the first-to-die's $3M exemption.

The credit shelter trust strategy requires asset equalization — the first-to-die must have at least $3M in their name to fund the trust. If assets are concentrated in one partner's account (a common LGBTQ+ household pattern when one partner earns significantly more), begin asset equalization now via annual gifting or retitling with an estate planning attorney.

4. Lifetime Giving: No Washington Gift Tax

Washington does not have a gift tax. This means lifetime gifts to reduce the taxable estate below $3M face no state-level gift tax, even for gifts that are too large for the federal annual exclusion ($19,000 per recipient in 2026). The federal gift tax applies to large gifts, but with a $15M lifetime exemption (OBBBA), most households have ample room for strategic gifting without owing federal gift tax either.

For LGBTQ+ couples approaching the WA estate tax threshold: an annual gifting program to children, grandchildren, or chosen-family beneficiaries at $19,000 per recipient removes assets from both partners' taxable estates without any WA gift tax cost. A couple with two adult children can remove $76,000 per year ($19,000 × 4 pairs) with no tax cost at any level. Over 10 years, that is $760,000 outside the estate.

For domestic partners (unregistered) considering large inter-partner transfers: WA has no gift tax, but federal gift tax applies to transfers between unmarried partners above $19,000 per year. The unlimited marital deduction (IRC §2056 and federal gift exclusion IRC §2523) does not apply to unregistered DPs — only to married spouses. Large inter-partner transfers for unregistered DPs require careful planning against the $19,000 annual exclusion and the $15M federal lifetime exemption.

5. Washington Capital Gains Tax: 7%/9.9% Tiers and LGBTQ+ Planning Angles

Washington is one of the few states with a standalone capital gains tax. Enacted in 2021 (SB 5096), validated by the state Supreme Court in 2023, and expanded to a two-tier structure under SB 5813 (retroactive to January 1, 2025), the WA capital gains tax applies to net long-term capital gains above the annual deduction:⁶

• 7% rate: net long-term capital gains above ~$262,000 (the annual standard deduction, inflation-adjusted; 2026 value — verify with WA DOR before year-end)
• 9.9% rate: net long-term capital gains above $1,000,000
• Exempt: real estate sales, retirement account withdrawals (401k, IRA, Roth), and livestock/certain agricultural assets

Combined with the federal capital gains rate (15% or 20% depending on income) and the 3.8% NIIT, Washington high-earners can face an all-in capital gains rate of up to 33.7% on gains above $1M. This materially changes investment planning decisions — particularly for LGBTQ+ tech, equity, and business-owner households in the Seattle area.

LGBTQ+-specific angles on the WA capital gains tax

Married same-sex couples vs. RDPs: the WA return filing difference

Married same-sex couples file a joint WA capital gains return. Their combined gains are measured against a single ~$262,000 annual deduction. RDPs (community property) split their community gains 50/50 — each partner has their own ~$262,000 deduction, effectively creating a $524,000 household-level floor before the 7% rate applies. For RDP couples with asymmetric investment portfolios (all gains concentrated in one partner's assets), this community property split can reduce WA capital gains tax significantly vs. what a married couple would pay on the same household gains.

Concentrated stock from equity compensation

Tech and startup employees in Seattle with RSU vesting or ISO/NSO exercises are the primary people paying WA capital gains tax. For LGBTQ+ equity compensation holders, the married vs. DP distinction matters for the WA return as above. Additionally, unregistered DP couples cannot take advantage of gift-splitting to shift gains to a lower-bracket partner; married spouses can coordinate gain-recognition timing more freely within the community property framework.

QSBS and WA capital gains

Federal QSBS (IRC §1202) excludes up to $15,000,000 of gain on qualified small business stock from federal capital gains tax (OBBBA raised this from $10M). Washington's capital gains tax does not adopt the federal §1202 exclusion — WA taxes QSBS gains subject to its own rules. LGBTQ+ founders and early employees in Washington who expect large QSBS gain events should model the WA capital gains exposure separately from their federal analysis.

6. WA Paid Family and Medical Leave: RDPs Covered as Spouses

Washington's Paid Family and Medical Leave program is one of the most comprehensive in the country — and one of the few state PFML programs that explicitly covers registered domestic partners on the same terms as spouses.

Coverage for RDPs

Under WA PFML, the definition of family member for family leave includes a "spouse," with "spouse" defined to include a state registered domestic partner. This means a registered domestic partner can take WA PFML leave to care for their seriously ill or hospitalized partner, bond with a newborn or newly adopted child, or address qualifying military exigencies — with job protection and wage replacement — on the same terms as a married spouse.⁷

Key 2026 changes

• Job protection threshold lowered: effective January 1, 2026, you qualify for job protection if your employer has 25 or more employees and you have been employed for 180 days — no minimum hours-worked requirement. This benefits part-time LGBTQ+ workers who were previously excluded.
• Healthcare continuation required: employers required to provide job-protected PFML leave must now continue your healthcare coverage for the full duration of WA PFML leave. This is significant for same-sex married couples and RDPs whose partner carries employer health coverage.
• Minimum leave increment: reduced from 8 consecutive hours to 4 consecutive hours, enabling intermittent leave for partial-day caregiving needs.
• Premium rate: 1.13% of wages in 2026, split 28.57% employer / 71.43% employee for employers with 50+ employees.

The gap for unregistered domestic partners

WA PFML covers registered domestic partners — not unregistered domestic partners. A younger LGBTQ+ couple (both under 62) who are not married and cannot register a new WA RDP have the same PFML gap as unmarried couples in other states: leave to care for an unmarried partner does not qualify as WA PFML family leave. The partner can use accrued PTO or sick leave (depending on employer policy), but there is no WA PFML job protection or wage replacement for the caregiving need.

Federal FMLA covers leave for a legally married same-sex spouse (using state-of-domicile marriage recognition) and — given Washington's explicit RDP treatment — likely extends to WA RDPs for FMLA purposes under DOL rules. However, unregistered DPs are not covered by federal FMLA.

7. Social Security for WA Same-Sex Couples and RDPs

Married same-sex couples — full benefits

Washington married same-sex couples have full Social Security spousal and survivor benefit access. The SSA marriage date runs from December 6, 2012 (the first day of marriage equality in Washington), or from the date of any earlier out-of-state marriage the SSA chooses to recognize retroactively. If you were in a WA RDP that was converted to a marriage in 2014, your SS marriage date is the date of the legal marriage conversion (June 30, 2014 at the latest, unless you married earlier), not the date of the original RDP registration. If Social Security seems to be using the wrong marriage date, contact the SSA directly to correct it. Use our Same-Sex Couple Social Security Strategy Calculator to model optimal claiming strategies.

Registered domestic partners — zero federal SS recognition

Washington's RDP is a state-law construct. Federal Social Security law does not recognize it. A state-registered domestic partner receives $0 in Social Security spousal benefits (50% of your partner's PIA while both are alive) and $0 in survivor benefits (up to 100% of their benefit after death). The financial lifetime gap for RDP couples where one partner has significantly higher earnings is measured in hundreds of thousands of dollars. Use our SS Survivor Gap Calculator to see your specific annual and lifetime shortfall.

Pre-2014 RDP and SS retroactive claims

Some same-sex couples who registered a Washington RDP before same-sex marriage became available in December 2012 may have questions about whether benefits run from the RDP registration date or only from the marriage date. Social Security recognizes marriages, not RDPs. However, if you married another state that had earlier marriage equality and SSA has recognized that out-of-state marriage retroactively, you may have a marriage date earlier than December 2012. Contact SSA directly or work with an advisor to confirm your benefit eligibility date.

8. Medicaid CSRA: RDP Gets Up to $162,660 — Unregistered DP Gets $2,000

Medicaid's Community Spouse Resource Allowance (CSRA) protects a portion of a couple's countable assets for the non-applicant spouse when one partner applies for Medicaid long-term care. In Washington, the RDP community property framework extends Medicaid spousal impoverishment protections to registered domestic partners — creating a stark difference between RDP and unregistered DP households.

Washington CSRA 2026 for married/RDP couples

Washington uses a tiered CSRA structure:⁸

• If combined countable assets are up to $145,058: the community partner retains 100% of assets, up to $72,529.
• If combined countable assets exceed $145,058: the community partner retains 50% of assets, up to a maximum of $162,660.

This protection applies to married same-sex couples and — through RCW 26.60 — to state registered domestic partners. If one partner in a WA RDP needs nursing home care costing $10,000–$12,000 per month, the other partner can retain up to $162,660 in countable assets without having to spend down the entire household savings before the applicant qualifies for Medicaid.

Unregistered domestic partners: $2,000 single-applicant spend-down

An unmarried partner who is not state-registered has no Medicaid spousal relationship with their partner. If they need long-term care, they qualify as a single individual — and Washington requires a single Medicaid applicant to spend down all countable assets above $2,000 before qualifying. Two separate households, two separate spend-downs, with no CSRA protection at all. For a couple with $500,000 in combined savings, the difference between CSRA protection ($162,660 retained) and single-applicant treatment ($2,000 retained) is $160,660 in direct financial exposure. See our LGBTQ+ Medicare and Long-Term Care Planning guide for the full LTC planning framework.

9. No State Income Tax: Retirement and IRMAA Advantages

Washington has no state income tax on wages, salaries, retirement income, or investment income. This is a major advantage for LGBTQ+ retirees, particularly those with large pre-tax retirement account balances where every dollar of withdrawal in retirement is subject to federal income tax but zero Washington state tax. For comparison: a retiree in Oregon faces a top state income tax rate of 9.9% on the same distributions; in California, up to 13.3%.

Roth conversion in Washington

The no-income-tax environment makes Roth conversions in Washington less costly at the state level than in most states — there is no state income tax on the converted amount in the conversion year. For LGBTQ+ domestic partner households doing Roth conversions specifically to reduce the inherited IRA 10-year forced distribution tax burden (see our LGBTQ+ Roth Conversion Planning guide), Washington's no-income-tax rule means only federal tax applies to conversions, not a layered federal+state cost. This is a meaningful advantage vs. a couple doing the same conversions while living in California or Oregon.

IRMAA planning — WA retirement community note

Medicare IRMAA surcharges are based on federal MAGI, not state income. Washington's lack of state income tax does not directly affect IRMAA — but the Roth conversion strategy enabled by WA's low-tax environment does. By converting pre-tax accounts to Roth earlier (in lower federal-income years), WA LGBTQ+ households reduce future MAGI and keep themselves below the $109,000 single-filer IRMAA threshold (vs. $218,000 for MFJ). Use our Medicare IRMAA Calculator to compare the DP vs. married single-threshold difference on your projected Medicare premiums.

Washington capital gains tax caveat

The no-income-tax advantage has one notable exception: the WA capital gains tax (7%/9.9%) applies on top of federal capital gains tax. Washington retirement accounts (401(k), IRA, Roth IRA) are exempt from the WA capital gains tax — withdrawals are not treated as capital gains. But gains on taxable brokerage accounts above ~$262,000 per year are subject to WA capital gains tax regardless of retirement status.

10. Relocating To or From Washington: What Changes

Moving to Washington

Married same-sex couples moving to Washington gain the community property regime automatically. This means wages earned after the move, and assets purchased with those wages, become community property going forward. Assets brought in from another state retain their prior character — a valuable brokerage account accumulated in Illinois (common law) does not become community property just because you moved to Washington. Only post-move community earnings do.

For a couple moving mid-year from a common-law state to Washington, federal Form 8958 must be filed for the Washington portion of the year (allocating community income from the date of domicile change). Working with a CPA familiar with community property transitions is important in the move year to avoid reporting errors.

Moving to Washington also means your estate plan should be reviewed and updated: WA community property treatment of assets, the $3M WA estate tax exemption (vs. no state estate tax in Texas or Florida), and the potential need for a credit shelter trust are all different from what your documents may have been written to address. See our LGBTQ+ Interstate Relocation Financial Planning guide.

Moving out of Washington

Washington community property character generally follows the assets. If you move to a common-law state (like Illinois or Florida) with assets that are Washington community property, those assets remain community property — though the new state may not have rules about how to handle them at death or divorce. The community property step-up at death is a federal tax rule that applies to community property regardless of which state you live in at the time of death; Washington's community property characterization can travel and preserve that step-up even if you later live in a common-law state.

For RDP partners moving to a state with no RDP recognition: your WA RDP protections disappear under the new state's law. Hospital visitation, healthcare decision authority, and Medicaid CSRA protections do not automatically transfer. Estate documents (healthcare proxy, DPOA, advance directive) should be updated for the new state's requirements immediately. See our LGBTQ+ Interstate Relocation Financial Planning guide for the full pre-move checklist.

11. Washington LGBTQ+ Financial Planning Checklist

Legal status

• Confirm whether your existing relationship is a legal marriage, a WA state RDP, or neither — the financial planning differences are material.
• If you registered a WA RDP before December 2012 as a same-sex couple under 62, verify whether it was automatically converted to a marriage in 2014 (it likely was). Confirm your SS marriage date at ssa.gov/myaccount.
• If you are in a WA RDP (typically 62+) and have not analyzed the SS remarriage decision: run the SS survivor benefit math before deciding whether to formally marry. See SS Survivor Gap Calculator.
• If you are under 62 and not married: you cannot register a new WA RDP. Complete the five-document estate plan. See Powers of Attorney and Healthcare Proxy guide.

Washington estate tax ($3M, no portability)

• Estimate your combined net worth (home + retirement accounts + brokerage + life insurance death benefit + business). If it exceeds $3M, engage a Washington estate planning attorney.
• If combined estate is $3M–$6M: a credit shelter trust is almost certainly worth the legal cost and is the primary tool to preserve both partners' $3M WA exemptions.
• If assets are concentrated in one partner's name: begin asset equalization so the first-to-die can fully fund a $3M bypass trust.
• Remember: WA has no gift tax. Annual gifting to children and chosen-family heirs at $19,000 per recipient removes assets from the estate with no WA tax cost.

Community property and Form 8958

• Married same-sex couples: file jointly on WA returns and jointly on federal returns. Community property basis step-up applies automatically.
• RDPs: file individually on federal returns with Form 8958 to split community income. Verify your tax preparer is filing Form 8958 if you are in a WA RDP — this is commonly missed.
• Review your estate documents for community property titling: a will written in a common-law state may not correctly account for community property character. Have a WA estate attorney review if you moved here.

Washington capital gains tax

• If you have a concentrated stock position, RSU vesting schedule, or expect to sell appreciated assets this year, model the WA capital gains tax (7% over ~$262K, 9.9% over $1M) before triggering gains.
• WA retirement accounts (401(k), IRA) are exempt from WA capital gains tax. Taxable brokerage accounts are not.
• QSBS holders: federal §1202 exclusion does not eliminate WA capital gains tax on QSBS gains — plan separately for both.

PFML and benefits

• Registered domestic partners: confirm with HR that your RDP status is documented and that you are enrolled in WA PFML under the spousal family definition.
• Unregistered DPs: you do not qualify for WA PFML family leave to care for your partner. Evaluate disability insurance and emergency fund adequacy to cover an unexpected caregiving need. See our LGBTQ+ Disability Insurance guide.

Medicaid / LTC

• RDPs: WA CSRA protects up to $162,660 for the community partner if one of you needs long-term care. Verify your assets are titled and structured to maximize the CSRA.
• Unregistered DPs: if one of you needs LTC, you are treated as single individuals — $2,000 spend-down for the applicant. LTC insurance or a funded self-insurance strategy is the planning response. See our LGBTQ+ Medicare & LTC guide.
