IRS problem in Seattle? Tax law is unforgiving. Get a tax lawyer.
Washington has no state income tax — but the federal IRS, the Washington Department of Revenue (B&O tax, sales tax), and (since 2022) the Washington capital gains tax all apply. Federal cases run through the IRS Appeals Office, U.S. Tax Court, and the U.S. District Court for the Western District of Washington. Seattle has one of the deepest tax-controversy benches on the West Coast.
These 10 Seattle firms handle IRS audits, collections, criminal tax, offshore disclosures, and complex business tax planning.
How we picked these 10: We reviewed published verdicts and settlements, peer rankings (Best Lawyers, Super Lawyers, Chambers and Partners, Avvo), client review patterns, and bar association recognition. Firms that appeared consistently across independent sources made the list. We do not accept payment for placement, and we do not write sponsored reviews. More on our methodology →

The legal directory you find on Google has thousands of Seattle tax firms. Most are competent. A few are problematic. The patterns to avoid:
Guaranteed outcomes. No ethical attorney can guarantee a result. If a firm promises a specific recovery, dismissal, or visa approval, walk away.
The disappearing partner. You meet a senior partner at intake, then never speak to them again. The case is handled by an unsupervised junior or a paralegal. Ask in writing who will be your day-to-day attorney.
Pressure to sign immediately. Reputable firms give you the retainer in writing, time to read it, and the option to take it home. High-pressure intake is almost always a sign of a volume mill, not a craftsperson's practice.
No verifiable track record. The firm should be able to point to verdicts, settlements, peer rankings, or bar association recognition. "We've helped thousands of clients" is marketing copy. Specific numbers, named cases, and third-party rankings are evidence.
Vague fee terms. "Don't worry about cost" is a red flag. Every legitimate Seattle lawyer will give you a written engagement letter with the fee structure, what's covered, what triggers extra charges, and what happens if you fire them.
Most Seattle firms on this list offer a free initial consultation. Use it. Bring a list of questions and write down the answers. Compare across at least two firms before you sign.
Seattle is its own market. The procedure, the courts, and the strategy are city- and state-specific in ways that matter to your outcome.
Local courthouses matter. King County Superior Court at the King County Courthouse and the U.S. District Court for the Western District of Washington have judges, calendars, and procedures that shape how cases move. A firm that knows the local courthouse has an advantage.
Filing deadlines are strict. Notice of Claim windows for cases against the City or County, Statute of Limitations periods, and pre-suit certification requirements vary by case type and are unforgiving. A missed deadline often means a lost case — full stop.
Local procedure rules matter. Each court has its own forms, motion practice, and judge preferences. The right Seattle firm will know not just the law, but the unwritten rules of the courthouse you'll be in.
Local plaintiffs/defendants do well in front of local juries. Verdict patterns vary by venue, and a trial-capable firm uses venue strategically.
CPA prepares returns. Tax lawyer represents you in disputes, audits, criminal investigations, court.
Yes — 7% on long-term capital gains over $262K (2023) for individuals. Confirmed by WA Supreme Court in 2023.
Yes — willful evasion is a felony. Failure to file is also chargeable. Get counsel immediately if criminal.
FBAR (Form 114) required if foreign accounts over $10K. Penalties severe.
Washington's gross receipts tax — applies to nearly all businesses operating in WA.
One last thing. Choosing a lawyer is personal. Read the reviews. Call two or three firms before you sign. Ask each one: How many cases like mine have you taken to verdict in the last three years? The answer tells you everything. — The LawFirmSquare team
