The attorneys at Thorn Law Group have helped hundreds of individual taxpayers and businesses with undisclosed offshore financial accounts come back into tax compliance.

The IRS announced significant revisions to its fifth generation program, the Offshore Voluntary Disclosure Program (OVDP). According to the IRS, the modifications are designed to encourage more taxpayers to come forward and report their previously undisclosed foreign bank accounts and assets.

The announced modifications to the IRS Offshore Voluntary Disclosure Program were a surprise to the international tax community. This is because just months earlier, the IRS announced that they would be closing the OVDP. The IRS re-opened the program quietly, however with a few key changes. 

If you have unreported foreign financial accounts or have questions about IRS offshore reporting requirements, a tax lawyer in our Maryland office can help. Our legal team will carefully review your situation and identify the best path to bring your offshore accounts and assets into complete compliance with U.S. laws and regulations.


The Maryland tax attorneys at Thorn Law Group have over thirty years of collective experience representing clients dealing with sophisticated and sensitive tax law problems. Led by founding tax attorney Kevin E. Thorn, the firm is recognized as one of the leading national and international law tax law firms in the DC-Maryland region. Prior to joining our tax law practice, many of our lawyers served as legal clerks for the United States Tax Court and worked for the IRS as trial attorneys. This insight into the government’s processes and procedures, combined with the professional relationships we have developed throughout the U.S tax litigation system, positions our firm to effectively and efficiently resolve the most difficult and complex tax law issues.

If you have questions concerning a civil or criminal tax law matter, including the IRS offshore voluntary disclosure program, we encourage you to schedule a legal consultation with a tax lawyer at our firm. You can reach our Maryland satellite office by calling 240-235-5096 or emailing Kevin E. Thorn, Managing Partner of the Thorn Law Group, at ket@thornlawgroup.com.
