Recent case law harmonisation by the Portuguese Supreme Administrative Court, selling inherited property in Portugal, followed by the alignment of the Portuguese Tax and Customs Authority (Autoridade Tributária e Aduaneira – AT), has finally clarified a long-standing and sensitive issue for heirs: the tax difference between selling an inheritance share (quinhão hereditário) and selling a specific asset of an inheritance.
This distinction is decisive for IRS capital gains taxation (Category G). It has practical consequences for notarial deeds, tax returns, and the correct completion of Annex G. Below, we explain the legal criteria, the applicable tax rules, and the most common mistakes to avoid.
What is at stake?
The key concept is the inheritance share (quinhão hereditário).
Under Portuguese civil law, an inheritance accepted but not yet divided constitutes an indivisible estate. Each heir holds an abstract, ideal quota in the inheritance as a whole. That quota may be transferred in two fundamentally different ways:
- Sale of the inheritance share (universal succession) – the heir transfers their position in the inheritance as a whole.
- Sale of a specific asset of the inheritance – typically a property, sold jointly by the heirs.
The tax treatment depends entirely on which of these two legal realities applies.
Under Article 10(1)(a) of the Portuguese Personal Income Tax Code (CIRS), capital gains taxation applies only to the onerous transfer of fundamental rights over immovable property. The legal question, therefore, is whether the transaction qualifies as such a transfer.
New jurisprudence and the Tax Authority’s current position
Following the harmonisation of case law by the Supreme Administrative Court, it is now settled that:
The sale of an inheritance share does not constitute the onerous transfer of a real right over immovable property for IRS purposes.
As a result, capital gains arising from the sale of inherited property in Portugal are not subject to IRS.
The Tax Authority has formally adopted this interpretation and issued binding administrative guidance confirming its practical application.
Decisive requirements (per AT instructions)
For the transaction to be treated as a non-taxable sale of an inheritance share, the deed must clearly and unequivocally show that:
- The object of the sale is the inheritance as a whole or the inheritance share, not a specific asset.
- The buyer assumes the legal position of an heir, acquiring the right to participate in future partition of the estate.
If the deed identifies a specific property as the object of the sale, the exemption does not apply.
When is the IRS capital gains tax due?
Capital gains tax applies when the heirs sell a specific, identified property that is part of the inheritance.
In these cases, there is a direct transfer of fundamental rights over immovable property, falling squarely within Article 10(1)(a) CIRS. The gain must be reported in Annexe G.
Typical taxable situations include:
- The joint sale of a specific property by the heirs.
- The sale of the last remaining property of the inheritance (the fact that only one asset remains does not convert the transaction into a sale of the inheritance share).
When is there no IRS taxation?
There is no IRS capital gains taxation when the heir sells their inheritance share as a universal right, provided that:
- The deed explicitly refers to the sale of the inheritance share or right to the inheritance.
- No specific property is identified as the object of the transaction.
This is a purely legal qualification issue, and the wording of the deed is often decisive.
Special exemption for seniors: when does it apply?
Article 10(7) of CIRS provides a capital gains exemption for taxpayers aged 65 or over, or retired, subject to reinvesting the proceeds in particular financial products.
However, this regime is frequently misunderstood.
Key rule
This exemption only applies to the sale of a taxpayer’s primary residence (habitual and permanent home).
If the property sold was not the taxpayer’s primary residence, the exemption does not apply, regardless of age or retirement status.
Additional requirements include:
- Reinvestment within six months of the sale.
- Investment in eligible financial products (life insurance, pension funds, RPc or PEPP).
- Structured payouts for a minimum of 10 years.
- Formal declaration of reinvestment intent in the year of sale.
A standard error assumes this is a general senior tax relief. It is not.
Completing Annex G: best practices
When a taxable sale of a specific inherited property occurs:
- Declare the transaction in Annex G, Box 4.
- If the property was acquired in stages (e.g. through successive inheritances), each acquisition must be declared separately.
- Acquisition and sale values must comply with Articles 44 and 45 of the CIRS.
- Confirm whether the property qualified as a primary residence and whether reinvestment regimes apply.
Failure to split acquisitions correctly is one of the most frequent sources of assessment corrections and penalties.
Frequently asked questions
- If I sell my share of a property to another heir, is it taxable? Yes, if the sale concerns a specific property. Only the sale of the inheritance share as a universal right escapes taxation.
- If only one property remains in the inheritance, does selling my part avoid tax? No. Selling a specific asset is still taxable, even if it is the last remaining one.
- Can I avoid tax by reinvesting in financial products within six months? Only if the property sold was your primary residence, and all statutory conditions are met.
Conclusions and recommendations
The correct tax outcome depends on a precise legal qualification of the transaction:
- Inheritance share (universal right): generally not subject to IRS capital gains.
- Specific property: generally subject to IRS capital gains and reporting in Annexe G.
- For senior taxpayers, always verify whether the property qualifies as a primary residence before relying on special exemptions.
Above all, ensure that the notarial deed accurately reflects the intended legal transaction. In this area, drafting is not a formality; it is often decisive for taxation.
Early legal and tax review significantly reduces the risk of reassessments, penalties, and litigation.
