When a Tax Problem Becomes a Tax Defense
Tax defense is the legal representation of businesses and individuals facing enforcement action by the IRS or a state tax agency. That enforcement can take the form of an audit, a collections action, a criminal investigation, or a combination of all three — and the strategy required to resolve each is fundamentally different.
The distinction between tax compliance and tax defense matters because the tools are different. A CPA files returns. A tax defense attorney intervenes when the government has already decided you owe more than you reported, you failed to file, or your conduct warrants criminal prosecution. The stakes are not just financial — they include personal liability, asset seizure, and in criminal cases, imprisonment.
Brotman Law is a San Diego tax law firm that represents clients exclusively in tax controversy and tax strategy matters. We do not prepare returns, sell financial products, or refer cases to other firms. Every attorney in our office works on tax disputes — IRS audits, criminal tax investigations, California state agency enforcement, and tax debt resolution. This page is the starting point for understanding what we do and how to find the right service for your situation.
Federal Tax Defense
Federal tax disputes involve the Internal Revenue Service and, when litigation is necessary, the U.S. Tax Court, Court of Federal Claims, or federal district court. The federal enforcement apparatus includes civil audit divisions, the IRS Office of Appeals, and for criminal matters, IRS Criminal Investigation (CI) and the Department of Justice Tax Division.
Audit Defense
IRS Audit Defense
Correspondence, office, and field audit representation. We control the information flow from day one — responding to IDRs, attending examiner meetings, and contesting proposed adjustments before they become assessments.
Learn more →Criminal Defense
Criminal Tax Defense
Representation during IRS CI investigations, grand jury proceedings, and DOJ Tax Division prosecutions. Tax evasion, fraud, willful failure to file, and promoter penalties.
Learn more →Litigation
Tax Litigation & Tax Court
When administrative remedies are exhausted or the IRS refuses a reasonable resolution, we litigate. U.S. Tax Court, Court of Federal Claims, and federal district court actions.
Learn more →Appeals
IRS Appeals
The IRS Office of Appeals resolves most disputes without litigation. We prepare Appeals protests, attend conferences, and negotiate settlements that avoid Tax Court entirely.
Learn more →California Tax Defense
California operates three independent tax agencies — the Employment Development Department (EDD), Franchise Tax Board (FTB), and California Department of Tax and Fee Administration (CDTFA) — each with its own audit procedures, penalty structures, and appeal paths. A business operating in California can face enforcement from all three simultaneously, plus the IRS, creating compounding exposure that requires coordinated defense across every agency.
California Sub-Pillar
California Tax Defense Hub
Coordinated defense across all three California tax agencies. Worker classification, sales tax, income tax, and state debt resolution.
IRS Tax Debt Resolution
When the IRS assessment is final and the amount owed exceeds what you can pay in full, the question shifts from "how much do I owe" to "what's the best resolution path." The IRS offers several formal programs — but the right program depends on your financial situation, compliance history, and the type of tax debt. Choosing the wrong resolution path wastes time, triggers additional penalties, and can eliminate options that would have been available earlier.
Debt Settlement
Offer in Compromise
Settle your tax debt for less than the full amount owed. We prepare Form 656, calculate reasonable collection potential, and negotiate with the IRS Centralized OIC Unit.
Learn more →Penalty Relief
Penalty Abatement
Remove failure-to-file and failure-to-pay penalties through first-time abatement, reasonable cause, or statutory exception arguments. Penalties often exceed the underlying tax.
Learn more →Spouse Relief
Innocent Spouse Relief
If your spouse or former spouse understated tax on a joint return, you may qualify for relief from joint and several liability under IRC §6015.
Learn more →Payment Plans
Installment Agreements
Structured payment plans for tax debt you can't pay in full. Streamlined, guaranteed, and partial-pay installment agreements based on your financial situation.
Learn more →Asset Protection
Tax Liens & Levies
Release federal tax liens, stop wage garnishments, and lift bank levies. We negotiate lien subordination, discharge, and withdrawal where available.
Learn more →Specialized Tax Defense
Some tax disputes require subject-matter expertise beyond general audit defense. Multi-state nexus issues, international reporting obligations, cryptocurrency transactions, cannabis industry compliance, and tax shelter investigations each involve distinct legal frameworks and enforcement patterns.
Multi-State, Residency & Nexus
Residency disputes, nexus determinations, and multi-state tax controversy for businesses and individuals operating across state lines.
Learn more →International Tax
FBAR, FATCA, streamlined filing compliance, offshore voluntary disclosure, and international reporting penalty defense.

Learn more →Tax Shelter & Promoter Issues
Defense against listed transaction penalties, promoter penalties under IRC §6700, and material advisor disclosure requirements.
Learn more →From Our Practice
In tax savings across all client matters since 2013. That number includes IRS audit reductions, penalty abatements, offer in compromise settlements, CUIAB hearing victories, criminal case resolutions, and proactive tax strategy implementations.
What makes the difference: Every case starts with a complete analysis of the client's exposure across all agencies — federal, state, and local. A client facing an IRS audit who also has California EDD exposure needs a coordinated strategy, not two separate attorneys working in isolation.

Frequently Asked Questions
Tax Defense Questions
What is the difference between a tax attorney and a CPA?
A CPA prepares tax returns and provides accounting services. A tax attorney represents you when the IRS or a state agency challenges what was filed — or when you face penalties, collections, or criminal investigation. Tax attorneys have attorney-client privilege (CPAs do not in most contexts), can represent you in Tax Court, and are trained to handle adversarial proceedings where the government is actively pursuing enforcement action.
How much does tax defense cost?
Fees depend on the type and complexity of the matter. IRS audit defense typically starts at a flat fee for correspondence audits, with field audits and Appeals cases priced based on scope. Criminal tax defense and litigation are quoted after an initial case evaluation. We publish our fee structure on our pricing page and discuss fees during the initial 15-minute consultation — before any engagement begins.
Do I need a tax attorney if I already have a CPA?
If you're facing an audit, collections action, or investigation, yes. Your CPA prepared the return that's being questioned — which means they may be a witness, not your advocate. A tax attorney provides independent representation with full attorney-client privilege and can coordinate with your CPA for return-related questions while maintaining the legal strategy your CPA is not trained to handle.
Can you represent me if I'm in another state?
Yes. IRS matters are federal and do not require the attorney to be located in the same state as the client. We represent clients nationwide in IRS audits, Appeals, Tax Court, criminal investigations, and tax debt resolution. For California state tax matters (EDD, FTB, CDTFA), we represent clients regardless of where they are located — the tax obligation arises from California-source income or California business activity.
What should I do if I receive an IRS notice or audit letter?
Do not ignore it — IRS notices have response deadlines that, once missed, eliminate administrative remedies. Do not call the number on the notice and discuss your case without representation. Contact a tax attorney immediately. We review the notice, determine the type of action (audit, adjustment, collections, or criminal), and file power of attorney (Form 2848) so the IRS communicates with our office from that point forward.
How long does tax defense typically take?
Timelines vary significantly. A correspondence audit may resolve in 60–90 days. A field audit typically takes 6–18 months. IRS Appeals cases average 6–12 months after the audit. Tax Court litigation can take 1–3 years. Criminal investigations may last 1–5 years from initial CI contact to resolution. We provide a timeline estimate during the initial consultation based on your specific situation.
