If you’ve received an audit notice at your home in Mill Valley, Tiburon, San Rafael, Sausalito, or anywhere else across Marin, you need experienced legal representation — not guesswork.

Kugelman Law — your tax and cryptocurrency team — represents Marin County taxpayers in federal and state tax audits from our Marin County office. We focus exclusively on tax controversy and cryptocurrency tax matters, and we understand the specific audit risks Marin residents face.

Our firm is led by Alex Kugelman, who has nearly two decades of experience representing clients in federal tax disputes — including matters before the U.S. Tax Court and U.S. District Court — and is a volunteer member of the Marin County Assessment Appeals Board.

Why Marin County Taxpayers Face Heightened Audit Risk

Marin isn’t a random audit target. Several factors make Marin County households more likely to face IRS and FTB scrutiny:

High income levels. Marin consistently ranks among the wealthiest counties in the United States. The IRS concentrates audit resources on high earners because the return on enforcement is greater.

Complex compensation. Many Marin residents work in San Francisco tech, finance, venture capital, and professional services, with compensation that includes stock options, RSUs, partnership interests, and deferred compensation.

Significant investment activity. Real estate, private equity, cryptocurrency, and foreign holdings are common — and all create audit exposure.

Residency issues. With remote work reshaping where people live, California’s FTB aggressively audits residents who claim they’ve moved out of state. Marin County taxpayers are among the most commonly targeted.

Pass-through entities. S-corporations, partnerships, and LLCs are frequent audit subjects, especially those with significant losses or deductions.

Common Types of Tax Audits in Marin County

At Kugelman Law, we defend Marin residents against the full spectrum of audit matters:

IRS Federal Audits. Including correspondence, office, and field audits for individuals, trusts, and businesses.

FTB California Residency Audits. California is notoriously aggressive in pursuing former residents. We defend clients who have relocated to Texas, Florida, Nevada, and beyond.

Cryptocurrency Audits. Marin has a notable population of crypto investors, founders, and early adopters. The IRS is actively pursuing crypto enforcement, and Alex Kugelman has built a nationally recognized specialization in digital asset tax controversy.

NFT Accounting and Tax Compliance. For Marin-based NFT creators, collectors, and investors navigating complex basis and reporting questions.

Pig Butchering and Crypto Scam Losses. For clients facing both the financial trauma of a crypto scam and the tax complexity that follows.

Unfiled Tax Return Resolution. For taxpayers who need to get back in compliance before the IRS or FTB finds them.

Tax Collection Defense. For clients facing liens, levies, or wage garnishments following an audit.

FBAR and Offshore Account Matters. Representation through the Streamlined Offshore Procedures, Delinquent FBAR Procedures, and Delinquent Foreign Information Return Procedures.

High-Net-Worth Audits. Including IRS Global High Wealth Industry Group examinations, which target wealthy families with complex structures.

The FTB Residency Audit: A Special Concern for Marin County

California’s residency audits deserve their own discussion because they’ve become so common in Marin County.

If you’ve moved out of California but still own a home in Marin, visit family in the Bay Area, or maintain business ties here, the FTB may challenge your claim of non-residency. The state looks at a long list of factors: where your driver’s license is issued, where your doctors and dentists are, where your kids go to school, where you spend holidays, where your bank accounts are held, and even where your pets live.

The stakes are enormous. California’s top marginal rate is 13.3%, and the FTB can go back multiple years. A failed residency audit can mean hundreds of thousands — or millions — in additional tax, interest, and penalties.

A tax audit attorney who understands FTB residency audits is essential. At Kugelman Law, we build comprehensive documentation strategies and negotiate directly with FTB auditors on behalf of our Marin clients.

Cryptocurrency Tax Audits in Marin County

The IRS has made cryptocurrency enforcement a top priority. If you’ve traded on Coinbase, Kraken, Gemini, or other exchanges that have received John Doe summonses, your data may already be in IRS hands. The agency is actively sending CP2000 letters, Letter 6173, Letter 6174, and Letter 6174-A notices to taxpayers whose reporting doesn’t match exchange records.

Alex Kugelman has been featured on the Bitcoin.tax podcast discussing topics including Kraken user data summonses, an insider’s perspective on IRS crypto enforcement, the anatomy of a cryptocurrency tax audit, and what causes crypto audits and how to respond. He has also appeared on The Mark Milton Show discussing cryptocurrency tax matters.

Marin County has a high concentration of early crypto adopters, founders, and investors — which means a high concentration of crypto audit risk. Our cryptocurrency accounting and audit practice handles:

• DeFi and liquidity pool reporting issues
• NFT transactions and basis disputes
• Staking and mining income characterization
• Lost or stolen crypto claims
• Exchange reporting discrepancies
• Hard forks and airdrops

What to Do When You Receive an Audit Notice

If you’ve received an audit notice from the IRS or FTB, take these steps immediately:

1. Don’t ignore it. Deadlines matter. Missed responses become default assessments.
2. Don’t call the auditor directly. Anything you say can and will be used against you.
3. Don’t hand over documents without review. Auditors often request more than they’re entitled to.
4. Engage a tax audit attorney. The earlier you have counsel, the better your outcome.

How Kugelman Law Defends Marin County Audit Clients

Our approach is straightforward. First, we analyze the audit notice and identify exactly what the IRS or FTB is examining. Second, we take over all communication so you don’t have to talk to the auditor directly. Third, we build a documentary record and develop legal arguments tailored to your situation. Fourth, we negotiate — whether that means resolving the matter at the exam level, appealing to IRS Appeals or the FTB Settlement Bureau, or litigating in U.S. Tax Court if necessary.

Proven Results for Our Clients

Our audit work has produced meaningful outcomes for clients, including a $365,000 tax debt reduced to a zero-dollar liability, successful resolution of a multi-year audit and non-filing matter with a minimal payment, and a favorable result for a client with ten years of unfiled returns. Results vary by case*, but the common thread is early, experienced representation.

What Is a Tax Audit?

A tax audit is an official examination of your tax return by the IRS or a state taxing authority like California’s FTB. The purpose is to verify that the income, deductions, and credits you reported are accurate. Audits can range from a simple correspondence audit conducted entirely by mail to a full-blown field audit where an agent visits your home or business.

In San Francisco, audits are especially common for taxpayers with:

• Self-employment or 1099 income
• Cryptocurrency transactions
• Large charitable deductions
• Foreign bank accounts or FBAR filings
• Stock options, RSUs, and tech compensation packages
• Rental properties in the Bay Area
• Cash-intensive businesses

Why You Need a Tax Audit Attorney in San Francisco

Many taxpayers make the mistake of trying to handle an audit themselves or relying solely on the CPA who prepared their return. That’s often a serious error. Here’s why a San Francisco tax audit attorney matters:

Attorney-client privilege. Unlike CPAs, attorneys provide full legal privilege. Anything you tell your attorney stays protected. Communications with your accountant can be subpoenaed.

Negotiation and litigation experience. Tax attorneys understand how to negotiate with revenue agents, appeals officers, and FTB auditors — and how to litigate in U.S. Tax Court if a negotiated resolution isn’t possible. We know which arguments work and which don’t.

Local knowledge. California’s FTB is one of the most aggressive state tax agencies in the country. A Bay Area-based tax attorney understands the nuances of California residency audits, Prop 19 issues, and the compensation structures common to San Francisco professionals.

Protection against escalation. What starts as a civil audit can sometimes turn criminal. An attorney knows the warning signs and can protect you before things spiral.

Types of Tax Audits We Handle

Kugelman Law represents San Francisco clients in a full range of audit matters:

IRS Audits. Correspondence audits, office audits, and field audits across all areas of federal tax law.

California FTB Audits. Including residency audits, which have become increasingly common as high earners relocate from California.

Cryptocurrency Audits. The IRS has made crypto a top enforcement priority. Alex Kugelman has built a unique specialization in cryptocurrency tax law and has appeared as a featured expert on the Bitcoin.tax podcast discussing IRS crypto enforcement, Kraken user data summonses, and the anatomy of a crypto audit.

NFT Accounting and Tax Compliance. For NFT creators, collectors, and traders facing basis, income recognition, and reporting questions.

Pig Butchering and Crypto Scam Losses. For taxpayers facing both the financial devastation of a crypto scam and complex tax questions about deducting those losses.

Unfiled Tax Return Matters. For clients who have fallen behind and need to get current before — or during — an audit.

Tax Collection Defense. When audits escalate to collections, liens, or levies.

FBAR and Foreign Account Matters. Representation through the Streamlined Offshore Procedures, Delinquent FBAR Procedures, and Delinquent Foreign Information Return Procedures.

What to Expect During an IRS Audit in San Francisco

Most audits follow a predictable pattern. Understanding it helps reduce the uncertainty.

First, you’ll receive an initial notice identifying the tax years and issues under review. Next comes the document request, often called an Information Document Request (IDR). Then there’s a fact-finding phase where the auditor examines your records and may interview you. Finally, the auditor issues findings — either a “no change” letter, a proposed adjustment, or a notice of deficiency.

At each stage, you have rights. You have the right to representation. You have the right to appeal. You have the right to go to Tax Court if necessary. A tax audit attorney ensures those rights are protected.

How Long Does a Tax Audit Take?

Most IRS audits in San Francisco are resolved within three to twelve months, though complex cases — particularly those involving cryptocurrency, foreign accounts, or large business entities — can extend beyond a year. FTB residency audits often take even longer because California aggressively pursues documentation of where you lived, worked, and spent your time.

Common Mistakes Taxpayers Make During Audits

After years of representing audit clients, we’ve seen the same mistakes over and over:

• Volunteering information that wasn’t requested
• Missing response deadlines, triggering default assessments
• Handing over years of unrelated records
• Trying to “explain away” discrepancies without documentation
• Waiting until the audit becomes a collection matter to hire counsel

The earlier you involve an attorney, the more options you have.

Proven Results for Our Clients

Audit outcomes can be transformative. Recent examples of our work include a client whose $365,000 tax debt was reduced to a zero-dollar liability, a successful resolution of a multi-year audit and non-filing matter with a minimal payment, and a favorable outcome for a client who had not filed tax returns for ten years. Every case is different*, but the pattern is consistent: early, skilled representation materially changes results.

Frequently Asked Questions About Tax Audits in San Francisco

How do I know if I’m being audited?

The IRS and FTB always initiate audits by mail, never by phone or email. If someone calls claiming to be an auditor and demanding immediate payment, it’s a scam.

Can a tax audit attorney help if I’ve already started the audit?

Yes. You can bring in an attorney at any point, even mid-audit. We regularly step in to take over cases that have gone sideways.

What’s the difference between a tax attorney and a CPA for an audit?

CPAs are excellent at preparing returns and understanding accounting. Tax attorneys are trained in legal strategy, negotiation, and litigation, and provide attorney-client privilege that CPAs cannot.

Will my audit turn criminal?

Most audits stay civil. But if the auditor suspects fraud — false documents, unreported income, hidden accounts — the matter can be referred to IRS Criminal Investigation. An attorney can spot the warning signs early.

Do you offer free consultations?

No. Kugelman Law provides high-end, white-glove tax representation, and we offer paid consultations with managing attorney Alex Kugelman. These consultations are privileged, confidential, and designed to give you substantive strategic guidance from the outset.

Do you represent clients outside San Francisco?

Yes. We serve clients throughout California and nationwide for federal tax matters.
