The investor base is heavy on software money. Amazon's headquarters anchors South Lake Union, Microsoft sits across the lake in Redmond, and Google, Meta, and a long tail of startups run large Seattle engineering offices. The typical client profile is an engineer with vesting RSUs, a decade-old Coinbase account, a hardware wallet, and a few years of DeFi experiments across chains. Each piece is manageable; the combination is what breaks consumer software.
The tax structure is the part outsiders get wrong. Washington's capital gains excise tax took effect in 2022, survived the state Supreme Court in March 2023, and survived the voters in November 2024 when Initiative 2109 failed. It applies a 7% rate to long-term gains above the standard deduction, $278,000 for 2025, and a 2025 law added 2.9% on taxable gains over $1 million. Real estate and retirement accounts are exempt. Crypto is not: it is intangible property, allocated to Washington when the owner is domiciled here at the time of sale.
The mechanics reward documentation obsessively. Only long-term gains count, so a lot's acquisition date determines whether a sale is Washington-taxable at all. The deduction means lot selection changes the state bill: a Seattle investor who realizes $270,000 of long-term gains in 2025 owes Washington nothing, while $500,000 of the same gains owes $15,540. Specific identification, supported per lot, is what turns those decisions from guesses into filings.
The deliverable covers both governments. We rebuild wallet, exchange, and DeFi history into per-lot Form 8949 detail, Schedule D totals, and Schedule 1 items, with holding periods documented well enough to drive the federal return and the separate Washington capital gains filing. Your CPA files both, or you file federally with TurboTax and handle the state return with the numbers we hand you.
