Cryptocurrency investors in Seattle face a unique tax landscape in 2025. While Washington state doesn’t levy personal income tax, residents must comply with federal IRS requirements and Washington’s own capital gains excise tax. With new IRS reporting rules and
Washington’s high-threshold tax structure, Seattle-based investors need to be extra cautious in their record-keeping and filing strategies this year.
This guide breaks down everything you need to know about crypto tax deadlines, Washington state reporting requirements, and smart strategies to stay compliant while minimizing risk.
Federal Crypto Tax Requirements in 2025
April 15, 2025 – The Big Deadline
For the 2024 tax year, all U.S. taxpayers must file by April 15, 2025. Crypto is treated as property by the IRS, meaning that sales, trades, staking rewards, mining income, and airdrops are all taxable events.
New Reporting Form: 1099-DA
Starting January 1, 2025, exchanges and crypto brokers must issue a new form called 1099-DA to report your gross proceeds from crypto sales. While this form won’t include cost basis or gain/loss data until 2026, the IRS will now have direct visibility into your transactions, making underreporting extremely risky.

Disclaimer
This tool provides an estimate only and should not be considered tax advice. Tax laws are complex and subject to change. The calculations are based on 2024 IRS tax brackets and Washington State capital gains excise tax provisions. For precise tax planning, consult a qualified Seattle-based tax professional.
How to Report
- Form 8949 & Schedule D: Report crypto disposals (sales, swaps, conversions).
- Schedule 1 or C: Report crypto income, such as mining or staking rewards.
- Cost Basis Method: Investors must select a cost basis method (FIFO, HIFO, or Specific ID) and use it consistently across accounts starting January 1, 2025.
Penalties Are Real
Failure to report can lead to civil penalties up to $100,000 or even criminal charges. With the IRS now receiving 1099-DA forms, enforcement will be stricter than ever.
Washington State Crypto Tax Rules
Unlike most states, Washington has no personal income tax. However, in 2022, the state implemented a 7% capital gains excise tax on certain high-value transactions—including cryptocurrency.
When It Applies
- The 7% tax applies to long-term capital gains (assets held longer than 12 months).
- It only kicks in when your total long-term gains exceed $270,000 for the year (2024 threshold, indexed annually).
- If you fall below this threshold, you don’t owe Washington state capital gains tax on crypto.
Example for Seattle Investors
Suppose you sell Ethereum in 2024 with a $300,000 long-term gain. You’ll pay 7% on $30,000 (the amount above the $270k exemption). Your Washington state liability would be $2,100, due by April 15, 2025.
Deduction Opportunities
- You can deduct up to $105,000 in charitable contributions to reduce taxable capital gains.
- This can be a valuable tool for Seattle investors with large portfolios.
Payment & Compliance
- Returns and payments must be filed through the Washington Department of Revenue (DOR).
- Crypto must be converted to USD fair market value at the time of the transaction—Washington does not accept tax payments in crypto.
Key 2025 Tax Dates for Seattle Crypto Investors
| Authority | Requirement | Deadline |
|---|---|---|
| IRS (Federal) | Report all crypto disposals & income | April 15, 2025 |
| IRS 1099-DA | Brokers report gross proceeds | Jan 1, 2025+ |
| WA State DOR | Pay 7% capital gains tax (if above $270k) | April 15, 2025 |
Strategies to Stay Ahead
1. Keep Meticulous Records
Track every trade, swap, and income event in USD. Include date, amount, cost basis, and proceeds. This is especially important now that brokers will report gross sales but not cost basis until 2026.
2. Choose Your Cost Basis Method Early
Pick between FIFO, HIFO, or Specific ID and apply it consistently across all wallets and exchanges starting in 2025.
3. Separate Federal vs. State Rules
- Federal IRS: All crypto disposals and income are taxable.
- Washington State: Only long-term gains over $270k are taxed. Short-term gains are ignored at the state level but fully taxed federally.
4. Leverage Deductions
If you’re over the Washington threshold, charitable contributions can reduce your liability.
5. Avoid Common Mistakes
- Leaving the crypto question on Form 1040 blank.
- Ignoring 1099-DA forms.
- Forgetting that Washington’s capital gains tax applies to long-term crypto only.
- Attempting to pay WA state taxes directly in crypto.
Tools & Local Resources
- Crypto Tax Software: Koinly, CoinTracker, TokenTax (ensure they support WA state capital gains tracking).
- IRS Digital Assets Hub: irs.gov/digital-assets
- Washington Department of Revenue: dor.wa.gov/capital-gains-tax
- Seattle Tax Professionals: Look for CPAs experienced in both federal crypto tax and Washington’s excise tax.
Final Word
For Seattle investors, 2025 brings increased IRS scrutiny through 1099-DA reporting and a still-new Washington capital gains tax. While Washington exempts most taxpayers with under $270k in annual long-term gains, high-value investors need to plan carefully to minimize liabilities.
The bottom line:
- Report all crypto federally by April 15, 2025.
- Check your Washington threshold—if over $270k, prepare for the 7% excise tax.
- Stay organized with records and tools.
- And most importantly: consult a Seattle-based tax professional for tailored advice.
Doing so ensures compliance, minimizes stress, and keeps your crypto gains working for you—not against you.
