A Growing Issue for Foreign Property Buyers in Portugal
Many expatriates and foreign investors purchase property in Portugal before actually relocating to the country.
A common scenario is where a taxpayer acquires a property intended to become their future permanent home, but substantial renovation works mean the property is not immediately habitable.
Recently, some taxpayers have reported receiving communications from the Portuguese Tax Authority (Autoridade Tributária e Aduaneira – AT) suggesting that the purchase of a property intended as a permanent residence may indicate Portuguese tax residency from the date of acquisition.
This raises an important question:
Can buying a property in Portugal automatically make you a Portuguese tax resident?
The short answer is: not necessarily.
Property Ownership and Tax Residency Are Different Legal Concepts
One of the most common misunderstandings in Portuguese tax law is the assumption that purchasing a property automatically creates tax residency.
In reality, two separate legal frameworks are involved:
1. IMT Benefits for Permanent Residence
The Portuguese Property Transfer Tax (IMT) rules provide favourable treatment when a property is acquired for:
- Habitação Própria e Permanente (HPP)
- Permanent residence purposes
These benefits are governed by the Portuguese IMT Code.
2. Portuguese Tax Residency
Tax residency is governed by Article 16 of the Portuguese Personal Income Tax Code (CIRS).
A person becomes a Portuguese tax resident if they:
- Spend more than 183 days in Portugal during the relevant period; or
- Have a dwelling in Portugal under circumstances that suggest an intention to maintain and occupy it as their habitual residence.
These are separate tests with separate legal consequences.
Does Buying a Property Automatically Create Tax Residency?
No.
The acquisition of a property alone does not automatically make someone a Portuguese tax resident.
The critical issue is whether the property was actually available and suitable for occupation as a habitual residence.
For example:
Scenario A
A foreign citizen purchases a fully furnished apartment in Lisbon in October 2025 and immediately moves in.
The Tax Authority may argue that the property satisfies the habitual residence test.
Scenario B
A foreign citizen purchases a property in October 2025 that requires extensive renovation works and cannot be occupied until February 2026.
In this situation, there is a strong argument that the property was not yet “in conditions to be occupied as a habitual residence” during 2025.
This distinction can be crucial when determining Portuguese tax residency.
The Importance of Renovation Works
Where a property undergoes significant construction or renovation after purchase, taxpayers should maintain evidence demonstrating that the property was not habitable.
Examples include:
- Construction contracts
- Invoices from contractors
- Municipal licences
- Utility installation records
- Completion certificates
- Photographic evidence
Such documentation can be essential if the Portuguese Tax Authority later questions the taxpayer’s residency status.
The Six-Month Rule for Permanent Residence Properties
A separate issue concerns the IMT rules applicable to permanent residences.
Under the Portuguese IMT Code, a property acquired with the intention of becoming the taxpayer’s permanent residence must generally be allocated to that purpose within six months of acquisition.
This requirement often creates confusion.
Many taxpayers assume that changing their fiscal address is enough.
However, the legal requirement is broader.
The taxpayer must generally demonstrate that the property became their actual permanent residence.
Changing the fiscal address is an important piece of evidence, but it does not automatically satisfy the substantive requirement on its own.
Is Changing Your Fiscal Address Merely a Formal Requirement?
Not entirely.
The change of tax address is usually viewed as evidence supporting the taxpayer’s intention to occupy the property permanently.
However, Portuguese tax law focuses on the factual reality.
The key question is:
Did the taxpayer genuinely begin using the property as their permanent home?
The Tax Authority may look beyond administrative registrations and examine the actual circumstances.
Can the Tax Authority Require a Taxpayer to Lose IMT Benefits?
In some cases, taxpayers have been told that they must relinquish IMT benefits if they wish to argue that they were not Portuguese tax residents during the year of purchase.
This position is debatable.
The two regimes serve different purposes and operate under different legal tests.
A taxpayer may be able to argue that:
- The property was acquired with the genuine intention of becoming a permanent residence.
- The property was still undergoing renovation works.
- The property was not habitable during the relevant tax year.
- Tax residency only arose later when the property became available for occupation.
Each case depends heavily on its facts and supporting evidence.
Key Evidence That Can Support a Non-Resident Position
Where residency status is challenged, taxpayers should gather:
Evidence of Renovation Works
- Building permits
- Contractor agreements
- Construction invoices
- Completion certificates
Evidence of Foreign Residency
- Tax residency certificates
- Employment contracts abroad
- Utility bills
- Foreign tax returns
Evidence of Physical Presence
- Travel records
- Flight tickets
- Passport stamps
- Accommodation records
These documents can be crucial in demonstrating that Portuguese tax residency had not yet commenced.
Practical Example
Imagine a taxpayer who:
- Purchases a property in Portugal in October 2025.
- Begins extensive renovation works immediately.
- Completes the works in February 2026.
- Moves into the property in March 2026.
- Changes their Portuguese tax address in March 2026.
In such circumstances, there may be strong grounds to argue that:
- The taxpayer was not Portuguese tax resident during 2025.
- The property only became suitable as a habitual residence during 2026.
- Any Portuguese tax residency should commence in 2026 rather than 2025.
The specific outcome will always depend on the individual facts and evidence available.
Frequently Asked Questions
Does owning a house in Portugal make me a tax resident?
No. Ownership alone does not automatically create Portuguese tax residency.
Can I buy a property before moving to Portugal?
Yes. Many foreign nationals purchase property months before relocating.
Do renovation works affect Portuguese tax residency?
Potentially yes. If a property is not habitable, this may be relevant when assessing whether it could qualify as a habitual residence.
Is changing my tax address enough to prove permanent residence?
Not necessarily. Portuguese tax authorities may also consider actual occupation and use of the property.
Can I keep IMT benefits and still argue that I was not resident during the purchase year?
Possibly. The two legal regimes are distinct, and each case should be analysed individually.
