Thorn Law Group
Thorn Law Group
Vienna, VA tax attorneys who dismantle IRS cases and protect what you've built.
The IRS doesn't send polite reminders. It sends penalties, audit notices, and collection letters designed to overwhelm. Thorn Law Group, based in Vienna, VA, was built specifically for moments like those. Attorney Thorn and his team don't negotiate from a position of fear; they go on offense, systematically challenging the IRS's claims until the numbers tell a different story.
Clients who have faced crushing tax penalties describe the experience the same way: they came in desperate and left with results they didn't think were possible. One business client saw the IRS's entire case dismantled. Another walked out of a 2020 audit with significant savings. That track record, reflected in a perfect 5.0 rating, isn't luck. It's a disciplined legal process applied to every case, no matter the size.
Thorn Law Group operates from Suite 350 on Old Gallows Road, serving individuals, business owners, and executives throughout Northern Virginia and the broader DC metro area. If you have a tax problem with teeth, this is the firm that bites back.
Tax law is a specialty, not a side practice. Thorn Law Group focuses exclusively on the intersection of tax law, compliance, and financial disputes, which means every tool in the firm's arsenal is calibrated for exactly the situation you're in.
Core services include IRS audit representation, tax penalty abatement, offers in compromise, tax debt negotiation, and back-tax resolution for both individuals and businesses. The firm also advises on tax compliance strategy, helping clients avoid future exposure before it becomes a crisis. Whether the IRS has initiated contact or you've discovered a problem on your own, the earlier you engage, the more options remain available.
Consultations are conducted with the directness clients consistently praise. You'll know where your case stands, what the realistic outcomes are, and what the legal strategy looks like before any work begins.
