By far, the most efficient Washington DC tax attorney in the area. Thorn Law Group saved my company a substantial amount, lowering the IRS penalties and fees we supposedly owed, to almost zero. Managing Partner Kevin E. Thorn found various critical errors the IRS had made during their tax audit investigation into my company. Choose the most thorough tax law legal representation in DC, choose Thorn Law Group.

I hired Thorn Law Group because they were suggested by a friend who had used their IRS Tax Audit services. There is no other tax law firm in the DC area I trust to handle my IRS audit when navigating the IRS. Managing Partner Kevin E. Thorn was diligent and understanding of my situation, and has decades of experience with IRS tax audits. In the end, Thorn Law Group saved my family hundreds of thousands in IRS taxes, interest and penalties.
