Background
Darrin founded the Law Offices of Darrin T. Mish, P.A. as a boutique practice focused on IRS tax resolution. Over three decades, the firm has resolved more than $100 million in outstanding tax liabilities for clients nationwide, working every collection alternative the IRS procedures allow — installment agreements, offers in compromise, currently-not-collectible status, penalty abatement, innocent spouse relief, and the full procedural machinery around federal tax liens.
The practice handles cases ranging from modest individual balances to complex multi-entity commercial controversies, including matters before IRS Collection, Examination, and Appeals, and litigation before the United States Tax Court. The firm represents taxpayers throughout the United States, not just in its home state.
Focus on federal tax liens in real estate transactions
A significant portion of the practice specifically involves federal tax liens that surface in real estate sales and refinances — the Certificate of Discharge procedure under §6325(b), the Subordination procedure under §6325(d), and the Withdrawal procedure under §6323(j). These are the specific tools that save closings, unlock refinances, and clean up the public record for taxpayers whose lives have moved beyond the events that produced the original lien.
The pattern is repeatable: a real estate agent, title officer, or mortgage broker encounters a federal tax lien in the middle of a transaction, has no experience with the procedural options, and has to either watch the deal die or find someone who does. That referral channel — agents and closers calling a tax attorney the day the lien surfaces — accounts for a meaningful portion of the firm's transaction work.
Credentials & bar admissions
Darrin is licensed to practice law in the State of Florida, the State of Colorado, and the State of Texas. He is admitted to practice before the United States Tax Court and multiple federal district courts. His Florida Bar number is 0931856.
Beyond the bar admissions, the practice stays current on IRS procedural changes through ongoing continuing legal education, active engagement with tax controversy professional communities, and direct practice volume. The IRS's Internal Revenue Manual, the governing policies and procedures, changes frequently in detail. The rules that applied to a lien discharge five years ago are not precisely the rules that apply today. Practice volume matters.
Media & public commentary
Darrin hosts The IRS Solution Attorney, a long-running podcast covering federal tax resolution topics for a general audience. He has been interviewed as a tax resolution authority by publications including the Wall Street Journal, CNN Money, Fox Business, and Investor's Business Daily, and has been quoted in discussions of IRS policy, collection practices, and tax controversy strategy.
The approach
The firm operates as a boutique — small enough that the attorney actually handles the case, large enough to have the procedural infrastructure needed for complex work. Every case starts with a free consultation, a transcript pull to establish the factual foundation, and an honest conversation about what's realistic given the numbers, the timing, and the transaction in front of us.
For real estate transactions specifically, speed matters. The earlier the attorney is engaged, the more options are on the table. The day a lien surfaces on a title commitment is the right day to pick up the phone. Two weeks before closing with a lien still on title is usually still saveable. Two days before closing usually is not.
Personal
Darrin lives in the Tampa area with his family on a 31-acre cattle farm outside the city. He is a longtime collector and restorer of vintage air-cooled Volkswagens, a practicing aikidoist, and generally partial to the view that mechanical problems — whether in an old VW bus or in an IRS case file — are usually solvable if you diagnose the actual cause rather than the surface symptom.
