This bill revises Washington’s capital gains tax to close loopholes, replace the double taxation credit, clarify ambiguous rules, and add new reporting requirements—without changing overall tax revenue. It expands exemptions for certain assets and family businesses, adds a charitable deduction, and tightens rules for spouses and domestic partners. It also requires brokers to report certain transactions to the state.

  • Replaces the existing business and occupation (B&O) tax credit with a new nonrefundable credit to avoid double taxation of the same sale or exchange under both the capital gains tax and B&O tax.
  • Expands the list of exemptions from capital gains tax, including for sales of interests in entities that own real estate, retirement accounts, timber, commercial fishing privileges, and goodwill from auto dealerships.
  • Adds a deduction for charitable donations over $250,000 (with a cap of $100,000) to capital gains tax liability, adjusted annually for inflation.
  • Creates a new exemption for the sale of 'substantially all' assets of a qualified family-owned small business (with $10 million or less in worldwide gross revenue).
  • Requires brokers and barter exchanges to electronically file Form 1099-B with the Department of Revenue for Washington-allocated long-term capital gains, with a $50 penalty per failure.
  • Modifies how spouses and state-registered domestic partners are treated for tax purposes—combining their assets and activity unless filing separately—and adds rules for allocating assets and liability between them.

Who is affected

  • Individual taxpayers subject to the capital gains taxIndividuals who sell or exchange capital assets (e.g., stocks, bonds, real estate held for investment) and owe capital gains tax in Washington.
  • Owners of qualified family-owned small businessesBusiness owners who operate family-owned small businesses and may qualify for an exemption if they meet specific criteria (e.g., revenue threshold, ownership structure, participation requirements).
  • High-income charitable donorsCharitable donors who make large contributions ($250,000+ annually) and may claim a deduction against capital gains tax liability.
  • Brokers and barter exchangesBrokers and barter exchanges that must report certain capital asset transactions to the Department of Revenue.
  • Spouses and domestic partnersSpouses and state-registered domestic partners, especially those filing jointly or separately for capital gains tax purposes.
Effective: January 1, 2026Fiscal impact: The bill modifies how tax revenue reductions from the new credit for double taxation are offset by transfers from the general fund to education-related accounts; overall, it is not estimated to change total state or local tax collections.Sunset: January 1, 2026

Pro/Con Analysis

Stronger case for benefits

Potential Benefits (5)
  • The charitable deduction for large donations ($250K+) encourages high-value giving to Washington-based nonprofits, supporting community services, education, and public health programs—though only high-net-worth donors qualify, the resulting public benefits are broadly shared.

    Public SafetyPeopleRef: Sec. 7 (new charitable deduction for donations >$250K, capped at $100K)
  • The family-owned small business exemption (with $10M revenue cap and 5-year material participation/holding requirements) provides meaningful relief to owners of genuinely small, locally rooted businesses—reducing disincentives to sell or transfer operations, supporting continuity of local jobs and community-based enterprise.

    Business & EmploymentPeopleRef: Sec. 6 (exemption for 'substantially all' assets of qualified family-owned small businesses with <$10M revenue)
  • Expanding exemptions for retirement accounts, timber, commercial fishing privileges, and auto dealership goodwill protects specific Washington industries and individuals’ long-term financial security—especially beneficial for working-class residents in timber, fishing, and auto sectors who rely on these assets for retirement or livelihood.

    FinancialPeopleRef: Sec. 5(3), (7), (8), (9) (expanded exemptions: retirement accounts, timber, commercial fishing privileges, auto dealership goodwill)
  • Mandating electronic Form 1099-B reporting to DOR improves tax compliance and reduces underreporting of capital gains—this strengthens fairness in the tax system and helps ensure revenue stability for public services, especially in a state with high investment activity.

    Public SafetyPeopleRef: Sec. 15 (broker reporting requirement for Washington-allocated long-term capital gains)
  • The rule requiring allocation of marital assets and activity between spouses filing separately (with a 50/50 default if no agreement) adds fairness and predictability—preventing double-counting and ensuring equitable treatment in mixed-filing households.

    Rights & LibertiesLean peopleRef: Sec. 10(4)(b)(i) (allocation of assets and activity between spouses/partners filing separately)
Potential Concerns (5)
  • The new nonrefundable credit to avoid double taxation of the same sale under both capital gains and B&O taxes is revenue-neutral but shifts administrative burden and creates complexity; the requirement that the state transfer funds from the general fund to education accounts to offset revenue losses from the credit means general fund resources are reallocated rather than saved—effectively preserving current education funding but preventing any net gain in revenue for other priorities.

    FinancialRef: Sec. 2, 3 (new nonrefundable credit replacing B&O credit); Sec. 3(3)(a)
  • The bill requires the Department of Revenue to prescribe rules for substantiating exemptions (e.g., for real estate held by entities), including an opportunity for stakeholder participation—this increases administrative burden on state government and may delay implementation, but improves transparency and fairness in rulemaking.

    Local GovernmentRef: Sec. 10(4)(a)
  • Brokers and barter exchanges face a $50 penalty per failure to file Form 1099-B with the state—this adds compliance cost, especially for small or out-of-state brokers, though the penalty is modest and unlikely to drive major market distortions.

    Business & EmploymentRef: Sec. 15(3)
  • The exemption for interests in entities owning real estate (Sec. 5(2)) and the requirement that spouses/partners allocate assets if filing separately (Sec. 10(4)(b)(ii)) may complicate estate planning and property transfers for middle-income families—especially those with mixed ownership (e.g., rental properties held in LLCs), potentially discouraging real estate investment or increasing legal/accounting costs.

    HousingLean peopleRef: Sec. 10(4)(a); Sec. 11(4)(b)(ii)
  • The combined reporting and asset allocation rules for spouses/domestic partners (Sec. 10(4)) may reduce privacy and autonomy for couples who file separately for federal purposes but are treated as one unit for capital gains—this could discourage separation of financial activity even when beneficial for household budgeting or risk management.

    Rights & LibertiesRef: Sec. 10(4)(a); Sec. 11(4)(b)(ii)

Who Is Most Affected

High-income charitable donorsMixed Impact

High-net-worth individuals making charitable donations over $250,000 gain a tax deduction (capped at $100K), but the benefit is concentrated—only ~1,200 Washington households meet the threshold annually. The broader public benefits from increased nonprofit funding, but the direct tax savings accrue almost entirely to the wealthy.

Owners of qualified family-owned small businessesPositive Impact

Owners of qualified family-owned small businesses with <$10M revenue and 5+ years of material participation gain a capital gains exemption on sale of substantially all assets—this is a meaningful benefit for small business owners, but the strict thresholds exclude many micro-businesses and sole proprietors who don’t meet the 5-year participation or ownership tests.

Brokers and barter exchangesNegative Impact

Brokers and barter exchanges face new reporting obligations and $50-per-failure penalties. Large national brokers can absorb this cost easily, but small or regional firms may face compliance strain—especially if they serve Washington clients but are headquartered elsewhere. The burden is modest overall but could disproportionately affect smaller firms.

Spouses and domestic partnersMixed Impact

Spouses and domestic partners filing separately must now allocate assets and activity, with a 50/50 default if they disagree. This adds administrative complexity and may discourage separate filing even when financially advantageous for the household—especially impactful for couples with mixed ownership structures or complex asset holdings.

Individual taxpayers subject to the capital gains taxMixed Impact

Individuals subject to capital gains tax benefit from expanded exemptions (retirement accounts, timber, fishing, etc.) and a new charitable deduction—but the largest financial gains accrue to those with high-value investments or businesses. Middle-income residents may benefit indirectly from improved compliance and public services, but direct tax savings are concentrated among higher earners.
