THEVOZ Attorneys is a tax law firm with offices in Austin, Geneva, and Lausanne specializing in the provision of tax and legal services to individuals and companies in United States and Europe. We help clients navigate a litany domestic and international tax issues ranging from compliance, to planning, and even litigation. We understand that each client has unique needs and goals, and we pride ourselves with taking a personalized approach to tailor our services to meet those needs.

As international tax attorneys that understand the concept of opportunity cost, or the strategic need to have a presence in a range of profitable markets and investing environments, THEVOZ Attorneys support our clients’ expansive business needs.

Tax Minimization

We believe that our clients should pay only the taxes that they are required to pay. As such we can help you legally plan around your tax responsibilities both at home and abroad. As Judge Learned Hand so eloquently put it: "Any one may so arrange his affairs that his taxes shall be as low as possible; he is not bound to choose that pattern which will best pay the Treasury; there is not even a patriotic duty to increase one's taxes." Gregory v. Helvering, 69 F.2d 809, 810 (2d Cir. 1934) (emphasis added). Let THEVOZ Attorneys assist you with minimizing your tax burden and ensuring that you are maximizing the tax efficiency of any given transaction.

In the international context, it is important to have professional representation to help you navigate and plan in the context of the relevant income and estate tax treaties that may be in effect. As a transatlantic firm, THEVOZ Attorneys are experts on tax treaties that may be relevant to you and your business. We can also help advise you when rule changes impact your tax liability.

Controversy Experience

Our attorneys have litigated cases before the Tax Court and they can handle a case through every step in the process. Litigation may start with an audit but it does not end until collection. It is important to have attorneys that understand the complete process from start to finish so that they can get you the best result possible. It is also important to have attorneys that have an understanding of the tactics that the IRS uses to examine and collect from taxpayers. That inside knowledge is rare and at THEVOZ Attorneys we are proud in the government experience of our Attorneys. Insider knowledge helps our clients get the best result and ensures that your case is being handled with a strategic eye.


These days it seems that compliance requirements are sprouting up faster than mushrooms after a rainstorm. The US system has numerous information returns and failure to property file these can have adverse effects on taxpayers. For instance, failing to file information returns for foreign accounts can lead to penalties of 50% or greater on the high balance in the account. And many taxpayers are unaware that they may be responsible for filings FBARs on the accounts of their foreign businesses.

Compliance with myriad tax rules in Europe and the United States requires familiarity with a wide range of topics and jurisdictions. THEVOZ Attorneys’ presence on both sides of the Atlantic and our diversity of clients means that we always up-to-date with tax compliance issues in the United States and Europe. Do not let compliance trip you up.

Taxation should never get in the way of your personal and professional aspirations.

Taxpayers that are seriously non-compliant may feel like they can do nothing but wait and see whether the federal government pulls their proverbial file. However, this fatalistic thinking is counter productive and fails to consider one important avenue for getting right with Uncle Sam: Voluntary Disclosure Practice. For serious offenders, those facing criminal exposure ratherRead More
