Residence and “tax residence” are different things. There are countries where you can be considered tax resident even if you don't step your foot there the whole year (often it's something like you having your family living there, or your business registered there). Some countries can treat you as tax resident by default if you are a citizen, unless proven otherwise, which you'd have to do in court if tax authorities decide to insist and you decide to disagree.
