When the IRS calls, hire a tax lawyer. Not a tax preparer.
Tax preparers do tax returns. CPAs do tax planning. Tax lawyers do tax fights — IRS audits, FTB controversies, collection actions, criminal tax, U.S. Tax Court litigation. SF tax practice is uniquely tech-equity-focused: ISO/NSO/RSU treatment, AMT, QSBS planning, and pre-IPO equity structuring.
These 10 SF tax firms cover the full spectrum: IRS controversy, CA SALT, international, criminal tax, and HNW tech-wealth 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 San Francisco tax and IRS 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 San Francisco 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 San Francisco 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.
San Francisco 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. the San Francisco Superior Court at Civic Center and the Northern District of California 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 San Francisco 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.
Both can help — but only a tax lawyer has attorney-client privilege.
OIC lets you settle tax debt for less than you owe.
Federal tax liens override CA homestead. A tax lawyer can stop most levies through CDP appeals.
FTB is more aggressive than the IRS in many ways. Many SF tax lawyers handle both.
Generally 3 years. 6 years if you understated income by 25%+. Unlimited if fraud or no return.
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
