Tax residency in Sao Tome and Principe
For São Tomé and Príncipe, the tax year is the calendar year. An individual is considered tax resident if they are present in the country for more than 183 days, consecutive or not, in any 12‑month period beginning or ending in that year, or if, on 31 December of that year, they have in São Tomé and Príncipe a dwelling under conditions that indicate it is intended to be kept and occupied as their habitual residence; individuals not meeting these criteria are treated as nonresidents. Where dual residence arises, applicable tax treaties resolve it using tie‑breaker criteria (typically permanent home, centre of vital interests, habitual abode, and nationality).
This summary is general information, not tax or legal advice. Rules change and individual circumstances vary — confirm with a qualified adviser before making decisions.
