About Us

A view of buildings in a city street.

When a tech consultancy owner outside Boston received an IRS notice demanding over $500,000 in unpaid payroll taxes, their CPA had no answers. They called Thorn Law Group, and the crisis became manageable. That kind of high-stakes intervention is exactly what this firm was built for, operating out of 10 Post Office Square in Boston's Financial District, steps from the federal courthouses where these battles are ultimately decided.

Founded by Kevin Thorn, the firm brings rare depth to tax controversy work. Kevin's combination of legal authority and accounting fluency means he reads an IRS assessment the way a surgeon reads an X-ray, spotting what others miss and building a response that holds up under pressure. Clients consistently highlight his attention to detail and his ability to stay genuinely responsive even when the stakes are highest.

This is not a generalist firm that handles the occasional tax dispute between closings and contract reviews. Thorn Law Group focuses on the intersection of tax law, finance, and federal compliance, serving individuals, business owners, and executives across Massachusetts and beyond who cannot afford a second opinion that arrives too late.

What We Offer

IRS tax controversy is the firm's core arena. When federal or state tax authorities issue notices, levies, liens, or audit demands, Thorn Law Group steps in immediately to assess exposure, halt collection action where possible, and negotiate from a position of legal strength. The firm handles payroll tax disputes, trust fund recovery penalties, offshore account disclosures, and criminal tax defense, areas where the margin for error is zero.

Beyond crisis response, the firm advises on tax planning and compliance for business owners, consultants, and high-net-worth individuals who want to stay ahead of liability rather than react to it. Services include penalty abatement requests, installment agreements, offers in compromise, and audit representation before the IRS, Massachusetts Department of Revenue, and U.S. Tax Court.

Every engagement starts with a candid assessment of your actual exposure and a clear strategy, not a vague promise. Clients who have sat across the table from federal agents describe the experience of having Kevin Thorn in the room as the turning point in their case.

"I own a tech consultancy outside Boston, and when I got hit with an IRS notice claiming over $500,000 in unpaid payroll taxes and penalties, I panicked. My CPA was in over their head — that’s when I found Thorn Law Group. Within weeks, Mr. Thorn had a full understanding of my case and had already begun challenging the foundation of the IRS’s claims. Mr. Thron uncovered how the IRS misclassified a chunk of my contractor payments, turning what seemed like a serious liability into a completely different, and far less damaging, situation. By the end, nearly all penalties were dropped. In Massachusetts, if you’re facing a tax nightmare, Thorn Law Group turns it into a story of survival — and success."

"Thorn Law Group took excellent care of us with an IRS tax matter that was incredibly stressful for our family. Kevin E Thorn, the managing partner, helped us identify that the IRS had indeed made a critical error. He reassured us that all would be figured out, kept us informed, and answered all of our questions. I'd highly recommend Thorn Law Group to anyone dealing with any type of tax issue, weather personal, small business, or corporate. With over 80 years of combined experience in law, they truly are the best tax attorneys in the Boston Mass area."

"Thorn Law Group and Mr. Thorn just helped my wife and I finish an IRS Audit. We received no changes, no additional tax and no penalties from the IRS. I can tell you this, I would never use a CPA, and only an attorney for any type of IRS audit. Mr. Thorn did a fantastic job and I highly recommend him and his firm!!"

Frequently Asked Questions

What types of IRS issues does Thorn Law Group handle?

The firm handles a broad range of federal and state tax matters including IRS audits, payroll tax disputes, trust fund recovery penalties, tax liens and levies, offshore account disclosures, offers in compromise, penalty abatement, and criminal tax defense. If the IRS or Massachusetts DOR has contacted you, this is the firm to call first.

My CPA said they can handle my IRS notice. Why would I need a tax attorney?

CPAs are excellent at preparation and compliance, but IRS enforcement actions, especially those involving penalties, criminal exposure, or significant back taxes, require legal representation. An attorney can assert privilege, negotiate settlements with binding authority, and represent you in Tax Court if needed. Several Thorn Law Group clients came to the firm after their CPA reached the limits of what they could do.

How quickly can Thorn Law Group respond to an urgent IRS matter?

The firm is known for responsiveness, which is one of the qualities clients cite most frequently in reviews. If you have received an IRS notice with a deadline or a revenue officer has made contact, reach out immediately. Early intervention almost always produces better outcomes than waiting.

Does the firm only serve clients in Boston and Massachusetts?

While the firm is based in Boston's Financial District, federal tax matters can be handled for clients across the country. IRS disputes, Tax Court cases, and offshore compliance issues are federal in nature, so geography is rarely a barrier to representation.

What is an offer in compromise and can it really reduce what I owe the IRS?

An offer in compromise is an IRS program that allows qualifying taxpayers to settle their debt for less than the full amount owed. The IRS accepts these offers when full payment would create financial hardship or when there is genuine doubt about the amount owed. Approval requires precise documentation and legal strategy. Thorn Law Group evaluates whether you qualify and prepares the strongest possible submission.

What should I bring to my first consultation?

Bring any IRS or state tax notices you have received, copies of recent tax returns if available, any correspondence with your CPA or prior representative, and a summary of the issue as you understand it. Do not worry if your documents are incomplete. The firm can help you reconstruct the picture and identify what is actually at stake.

How does Thorn Law Group charge for its services?

Fee structures vary depending on the complexity and nature of the matter. Some cases are handled on a flat-fee basis, while others may involve hourly billing. The firm provides a clear fee discussion during the initial consultation so there are no surprises. Given the financial exposure involved in most tax disputes, having skilled legal representation typically costs far less than the penalties and interest that go unchallenged.
