Thorn, the founding member and managing partner of the firm, has been featured in the Wall Street Journal special Capital Region’s Premier Lawyers supplement as a leading attorney in the DC metro area handling international, civil and criminal tax law cases.

Thorn Law Group has extensive experience representing clients seeking to participate in the IRS offshore voluntary disclosure program (OVDP). Our tax attorneys have an in-depth understanding of how the OVDP programs work and we have helped hundreds of clients in Virginia, the U.S. and around the globe to bring their unreported offshore bank accounts into full compliance with the law.

The IRS has made important changes to its OVDP since its inception. These changes were designed to increase the number of taxpayers voluntarily coming forward to report previously undisclosed offshore bank accounts. These changes came after the IRS closed the program for a period lasting only a few months. The modifications effect factors of an OVDP such as the assigned penalties, auditing window, and more.

Every change to the IRS Offshore Voluntary Disclosure Program is a preventative measure to ward off non-compliance with U.S. Tax Law. The OVDP was developed as to inspire taxpayers with offshore bank accounts to disclose them to the IRS.  The IRS OVDP has undergone many changes and versions. The IRS has listened to the taxpayer community as well as the US Tax Advocate Service and has responded accordingly.

Individuals and businesses residing in the Virginia area that have questions about offshore voluntary disclosures and the OVDP should consult with the experienced IRS voluntary disclosure attorney, Kevin E. Thorn, Managing Partner of Thorn Law Group that has over 50+ years of serving clients with offshore bank accounts and international assets.
