Crypto Gains and State Taxes: Records Before Relocation

A crypto relocation estimate needs the gain calculation and the applicable residence and sourcing rules. Comparing a token’s sale proceeds with a state’s top wage-tax rate can substantially misstate the result.

Reconstruct proceeds and basis first

Reconcile disposals across exchanges and wallets, including swaps and transactions that may not generate a complete broker statement. Separate sale proceeds from cost basis, fees and resulting gain. Keep acquisition dates because holding periods can affect federal treatment.

IRS Form 1099-DA reporting is phased in. Basis reporting for certain covered digital assets under the 2026 rules does not supply complete basis for all holdings, transfers or earlier acquisitions. Your own records remain necessary.

Establish the relevant dates and income character

Separate investment disposals from compensation, mining, staking and business transactions, whose treatment can differ. Record when income was recognized and where you actually lived or performed services. A change of mailing address before a sale does not establish a completed domicile change.

Part-year residence, continued statutory residence and business-source rules can affect which state taxes the item. Deferred compensation and work-related token awards need a different analysis from an ordinary investment held for your own account.

Treat Washington separately

Washington’s capital-gains excise tax applies to certain long-term capital gains, with deductions and exemptions. Beginning with tax year 2025, the rate is 7% on the first $1 million of taxable Washington capital gains and 9.9% above that amount. The threshold applies after the relevant statutory calculation, not to gross crypto proceeds.

The general deduction is adjusted annually. Do not reuse the $278,000 deduction for 2025 as a verified 2026 figure. Consult the DOR page for the year being calculated, allocation rules and exemptions. Describing Washington simply as a zero-tax state or a flat 7% state omits material conditions.

Model a move with the right inputs

• Gain and loss by transaction, with basis and holding period.
• Actual move date and homes available before and after it.
• Work-related or business-related income components.
• Each state’s residence, allocation and conformity rules.
• Federal tax and any foreign-country liability.

Our wage-based state comparison is not a crypto capital-gains return calculator. A representative wage saving cannot be applied to a large token sale without recalculating the tax base and applicable rules.

Keep a defensible transaction file

Retain exchange exports, wallet transfer reconciliations, source documents and contemporaneous move evidence. Use the records consistency guide for domicile evidence. Ask a preparer familiar with digital assets to review the recognition and state allocation before a material transaction.
