Before relocating to France, it’s crucial to understand the visa and tax requirements. EU nationals have the advantage of free movement and can live and work in France without a visa. Non-EU nationals, however, will need a long-stay visa if planning to stay longer than 90 days. This can later be converted into a residence permit. It's advisable to start the visa application process several months before your intended move. Regarding taxes, France has a progressive income tax system, and expats may be liable depending on their residency status. Generally, if you reside in France for more than 183 days a year, you are considered a tax resident. It’s important to declare your global income, and you might be subject to other taxes such as the wealth tax. Consulting with a tax advisor familiar with French and international laws can be beneficial to navigate these complexities effectively.
