About Our Firm

alliantNational specializes in helping CPAs and U.S. businesses navigate complex tax matters, offering both representation and support while working with tax agencies at every level. Our leadership team includes three former IRS Commissioners, Mark Everson, Steven T. Miller, and Kathy Petronchak, and the former Senior Counsel to the Senate Finance Committee that lead a team of experts including former IRS executives, congressional staffers, technical experts and seasoned litigators.
The firm, a division of alliantgroup, provides a unique advantage to its clientele through the group’s senior leadership team and veteran attorneys who have hands-on litigation experience and an in-depth knowledge of the Internal Revenue Code. We provide CPAs and American companies with support in specialized areas including audit and credit defense, controversy services, domestic and international tax planning and tax exempt services.
Not only do we have the leadership, the expertise, and the experience but we also have the results. Besides having ensured optimal results for tax-exempt organizations, international taxation issues, and captive insurance concerns, we have also reduced, reversed, and completely eliminated IRS penalties levied against our clients. Our results are undeniable and you can see the proof in our case studies.
The group takes proactive steps using its team’s keen understanding of the complexities involved with tax controversy matters today. That is the alliantNational advantage and we are ready to assist, support, and fight for you.
