Applicants must be able to prove earning sufficient passive income to support themselves in Portugal without relying on salaried income. Sources of income that qualify towards meeting this requirement include stable rental income from movable or immovable assets, monthly pension payouts, royalties and dividends. (Dividends can qualify, provided that you are not actively involved in the running of the company from which these payments are received.) You may be required to submit proof of significant available savings, in addition to the passive income requirement.
The minimum passive income thresholds for the program are discussed in more detail below. For starters, individual applicants are expected to earn at least €635 per month (€7,620 per year). It is, however, highly advisable to treat this as the absolute minimum requirement. The higher your passive income earnings, the more likely your visa is to be approved.
