A recurring issue Monaco encounters with other countries is the attempt by foreign nationals to use Monaco to avoid paying taxes in their own country. Monaco actually collects a number of taxes including a 20% VAT and 33% on companies unless they make over 75% of their income inside Monaco. Monaco does not allow dual citizenship but does have multiple paths to citizenship including by declaration and naturalisation. In many cases the key issue for obtaining citizenship, rather than attaining residency in Monaco, is the person's ties to their departure country. For example, French citizens must still pay taxes to France even if they live full-time in Monaco unless they resided in the country before 1962 for at least 5 years. In the early 1960s there was some tension between France and Monaco over taxation.
