Investing in stocks in Portugal has become increasingly common among Portuguese residents. However, dividend taxation rules remain complex and demand careful planning.
Portuguese tax residents are subject to worldwide income taxation. Therefore, dividends from both Portuguese and foreign companies must be reported and taxed in Portugal.
General Rule: Withholding tax at 28%
Dividends are classified as Category E income under the Personal Income Tax Code (CIRS). They are generally subject to a final withholding tax of 28%.
When a Portuguese company distributes dividends, or when a Portuguese intermediary pays them, the tax is withheld automatically. The investor receives net income, while the intermediary remits the tax to the State.
Regional Reductions: Madeira and Azores
Since January 1, 2025, residents in Madeira have benefited from a reduced rate of 19.6%, due to the 30% regional reduction.
The same reduction applies in the Azores. These regional benefits are grounded in legislation designed to mitigate insularity costs.
Aggregated Rate of 35%
An aggravated 35% withholding rate applies in specific cases, including:
- Dividends paid through accounts with unidentified beneficial owners.
- Dividends from entities located in blacklisted jurisdictions (Portaria 150/2004, as amended).
- Payments are made through non-resident entities without a permanent Portuguese establishment.
In these cases, there is no option to aggregate income.
Option to Aggregate (Englobamento)
Instead of flat taxation, residents may aggregate dividends into their annual taxable income. This option requires including all Category E income.
Under Article 40-A CIRS, only 50% of dividends are included when:
- Paid by Portuguese companies, or
- Paid by EU/EEA companies that meet the Parent-Subsidiary Directive requirements.
This partial relief mitigates double taxation, as profits are already subject to company-level corporate income tax.
Double Taxation of Foreign Dividends
Foreign dividends often suffer withholding in the source country. When also taxed in Portugal, this creates double taxation.
Portugal provides relief through a foreign tax credit (Article 81 CIRS). The credit is limited to the lower of:
- Tax actually paid abroad (within treaty limits), or
- The portion of Portuguese tax attributable to that income.
The credit is claimed in Annexe J of the Modelo 3 return.
Only the treaty rate is credited if the investor fails to use treaty procedures. For example, if the treaty allows 10% but the investor suffers 25% withholding, only 10% is creditable.
Reporting Obligations
Domestic dividends with Portuguese withholding:
- The declaration is optional unless aggregation is elected.
- Foreign dividends through Portuguese intermediaries: declaration optional if taxed at 28%, but required for credit or aggregation.
Foreign dividends without Portuguese withholding: mandatory declaration in Annexe J, taxed at 28% (or 35% if blacklisted).
Distinction Between Withholding and Special Rates
It is essential to distinguish between withholding rates (applied at payment) and special autonomous rates (applied during assessment).
Foreign dividends not subject to Portuguese withholding are taxed under Article 72 CIRS at 28%, or 35% for blacklisted jurisdictions.
Conclusion
Dividend taxation for Portuguese tax residents is far from straightforward. Residents must evaluate withholding rules, regional reductions, aggregation options, and double taxation relief.
Flat taxation and aggregation depend on income brackets, treaty application, and overall income profile. Careful calculation is essential to avoid excess taxation and ensure compliance.
