Phase 1 – Understanding the 2023 Reform
The Portuguese State Budget for 2023 introduced a fundamental change in how non-residents are taxed on real estate capital gains in Portugal.
Previously, non-residents benefited from a flat tax rate of 28% on capital gains arising from the sale of Portuguese property. This regime was straightforward and often advantageous.
However, this option was abolished from 2023 onwards.
As a result, non-residents are now taxed under rules broadly aligned with Portuguese tax residents, significantly altering both the calculation method and the effective tax burden.
Phase 2 – How Capital Gains Are Now Taxed
Under the current framework, the taxation of real estate capital gains for non-residents follows three key steps:
1. Calculation of the Capital Gain
The capital gain is determined under Article 10 of the Portuguese Personal Income Tax Code (CIRS), taking into account:
- Sale value
- Inflation-adjusted acquisition value
- Eligible costs and expenses
2. Partial Inclusion (50%)
Only 50% of the net capital gain is subject to taxation.
3. Mandatory Aggregation and Progressive Rates
This amount is then subject to:
- Mandatory aggregation (englobamento) under Article 22 of the Portuguese Personal Income Tax Code (CIRS)
- Application of progressive tax rates under Article 68 of the Portuguese Personal Income Tax Code (CIRS)
These rates can reach:
- Up to 48% standard rate
- Plus up to 5% additional solidarity tax
Phase 3 – The Critical Factor: Worldwide Income
A key feature of the new regime is often overlooked:
Non-residents must report their worldwide income to determine the applicable tax rate.
This requirement stems from Article 22(10) of the Portuguese Personal Income Tax Code (CIRS).
What does this mean in practice?
- Your foreign income is not taxed in Portugal (in most cases, depending on the applicable Double Tax Treaty)
- However, it is used to determine the progressive tax bracket applied to your Portuguese capital gains
This creates a rate escalation effect, often leading to significantly higher taxation.
Phase 4 – Practical Example
Consider the following scenario:
- Property sale price: €500,000
- Acquisition cost (adjusted): €409,500
- Expenses: €35,000
- Net capital gain: €55,500
Taxable portion (50%): €27,750
If the taxpayer also earns €100,000 abroad:
- Total income for rate purposes: €127,750
- Applicable marginal tax rate: approx. 50.5%
Final tax payable in Portugal: ~€11,391
Without foreign income, the effective tax rate would be significantly lower.
Key Risks and Common Mistakes
1. Underestimating the Impact of Foreign Income
Many taxpayers assume only Portuguese income is relevant — this is incorrect.
2. Using the Tax Authority Simulator
The Portuguese Tax Authority simulator may still reflect outdated rules and produce inaccurate estimates.
3. Incorrect Income Reporting
There is ongoing technical debate regarding:
- Gross vs net foreign income
- Applicable deductions
- Category-specific adjustments
A defensible approach is to apply resident-equivalent rules, meaning:
- Include only income subject to aggregation
- Apply relevant deductions (e.g., social security contributions)
Limitations for Non-Residents
Non-residents face several structural constraints:
- No access to the former 28% flat tax regime
- No effective choice between regimes for capital gains
- No joint taxation option
- No access to most tax deductions
Strategic Insight for Property Owners and Investors
This reform has materially increased the importance of pre-sale tax planning.
In particular, the following should be assessed before selling:
- Timing of the disposal
- Interaction with foreign income levels
- Potential residency status changes
- Application of Double Tax Treaties
For high-income individuals, the difference can be substantial.
