Match the permit to your work
Make a short list using your actual work arrangement: employee of an overseas company, freelancer with overseas clients, or business owner. On each official programme page, check whether local clients are allowed, which income documents are accepted and whether your employer must provide a letter. Do not assume that a permit for remote employment also covers a locally operated business.
Build a calendar before comparing tax rates
Write down planned arrival, departure and travel dates, and the homes you will keep available. Check the residence rules of both your current country and the destination. A visa duration and a tax-residence day test answer different questions; neither should be treated as a universal exemption from tax.
Check the practical cost of renewal
Compare the initial permission with the renewal conditions. Put health insurance, dependants, housing evidence, document translations and time away from the country in the same checklist as application fees. Ask your employer to assess payroll and social-security obligations before approving the move.
