Yes, Digital nomads are required to pay taxes in Portugal only if they reside in the country for 183 days in a year or have an official residence permit in Portugal. Digital nomads will be considered tax residents if they spend 183 out of 365 days in Portugal. If a digital nomad registers under NHR status (Non-Habitual Resident Status) after 183 days, they are liable to pay only 20% of the overall tax.
