When the IRS calls, hire a tax lawyer. Not a tax preparer.

Top 10 Tax and IRS Lawyers in Houston

Tax preparers do tax returns. CPAs do tax planning. Tax lawyers do tax fights — IRS audits, Texas Comptroller controversies, collection actions, criminal investigations, U.S. Tax Court litigation. Texas has no state income tax — but it does have franchise tax, sales tax, and aggressive Comptroller audits. The firms below handle both IRS and Texas state tax matters.

These 10 Houston tax firms cover the full spectrum: IRS controversy, Texas state and local tax (SALT), international tax, criminal tax defense, and high-net-worth 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 →

What to expect from a Houston tax engagement

An IRS audit notice typically gives 30 days to respond. Your tax lawyer files a power of attorney (Form 2848), responds to the IDR, and represents you. Cases that don't settle at audit can be appealed to IRS Appeals or petitioned to U.S. Tax Court. Criminal tax investigations require immediate counsel.

What does a tax lawyer in Houston cost?

Houston tax controversy work typically runs $400-$800/hour for partners. Audit defense often involves a flat fee per stage ($5,000-$25,000) or hourly + retainer. Offer in Compromise engagements: $3,500-$10,000+. Criminal tax defense is hourly with substantial retainers ($25,000-$100,000+).

Red flags to watch for when picking a tax and IRS lawyer in Houston

The legal directory you find on Google has thousands of Houston 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 Houston 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.

10 questions to ask in your free consultation

Most Houston 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.

  1. Who, specifically, will handle my case day-to-day? Get a name. Get an email.
  2. How many cases like mine have you handled in the last three years? You want a number, not a brochure line.
  3. What is your fee, and what does it cover? Get the answer in writing before you sign.
  4. What case expenses am I responsible for, and when? Out-of-pocket costs surprise people. Ask now.
  5. What is the realistic range of outcomes for a case like mine? A good lawyer will give you a range. A bad one will promise the high end.
  6. How long will it take? Honest estimate, with the assumptions stated.
  7. Who else might be involved? Experts? Co-counsel? Larger cases routinely involve outside experts. Know who's on the team.
  8. How and how often will I hear from you? Email-only? Calls? Monthly updates? Set the expectation now.
  9. What happens if I want to change lawyers later? Rules allow it; the fee is sorted between firms. Make sure you understand the mechanics.
  10. What's the worst-case outcome for my case? A lawyer who refuses to discuss downside risk is selling you something.

What's specific about a tax and IRS case in Houston

Houston 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. Harris County District Courts and the Southern District of Texas 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 Houston 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.

Frequently asked questions

Do I need a tax lawyer or a CPA for my IRS audit?

Both can help — but only a tax lawyer has attorney-client privilege. CPA-client communications are not privileged in criminal cases. If there's any chance the audit could escalate to criminal, hire a lawyer first.

What is an Offer in Compromise?

An OIC lets you settle your tax debt for less than you owe if you can show you can't pay it in full. The IRS accepts about 30-40% of OIC submissions.

Can the IRS take my house in Texas?

Texas has unlimited homestead protection from creditors generally — but federal tax liens (IRS) override state homestead law. The IRS can technically seize property, though it rarely does. A tax lawyer can stop most levies through Collection Due Process appeals.

What about Texas Comptroller audits?

Texas Comptroller audits franchise tax, sales tax, and use tax. Texas has aggressive audit and collection statutes. Many Houston tax lawyers handle both IRS and Comptroller matters.

How long does the IRS have to audit me?

Generally 3 years from filing. 6 years if you understated income by 25%+. Unlimited if you didn't file or the return was fraudulent.

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
