People who do not understand the language or who have complex income and wealth affairs should seek specialist advice from an accounting company (www.ztv-zug.ch) or lawyer (www.advokaten-zug.ch - German).

Many banks and not-for-profit organisations such as the Immigration Advisory Office (FMZ), the Federation of Trade Unions (German) or The Women's Advisory Service (German) can provide certain services or arrange for professional help.
