Partners in Creating Value

Andersen Tax knows that the best way to avoid controversy is to plan for it. Our controversy practice interacts with local client service teams on a regular basis, inviting local teams to involve the controversy practice before tax returns are filed and exam notices are sent. Often times, disputes can be avoided through good documentation and the development of fact patterns that support favorable tax positions. Andersen Tax controversy professionals include former government attorneys who provide a critical review of return positions and substantiation requirements before disputes arise with federal or state tax authorities. Whenever possible, Andersen Tax adds value to clients by resolving potential controversies before they materialize.
