The Portuguese framework
How tax disputes work in Portugal
Selling property, shares or a business in Portugal can trigger a tax bill, and the paperwork behind it is not always straightforward. If you are a resident, a non-resident, an expatriate or an heir dealing with a Portuguese asset, you may need a capital gains tax lawyer in Portugal to review how a transaction was reported, to answer the tax authority or to argue your position before the administrative and tax courts. Portuguese rules and reporting duties sit in written legislation, and how a gain is calculated, declared and challenged depends on your personal situation and on the asset involved. This page explains the system, the deadlines that matter and how to find a lawyer for your type of case.
Portugal in practice
How tax and property matters work in Portugal
Portugal applies written codes and a separate branch of courts for tax matters, so procedures and deadlines differ from what many foreign owners or expatriates expect. The notes below set out the framework that shapes a capital gains or property tax case in Portugal, drawn from official Portuguese and European sources.
Disputes go to a separate branch of the judiciary
Portugal follows the continental civil law model, and tax matters do not go before the ordinary civil courts. Under the Constitution the judicial courts and the administrative and tax courts form two distinct systems. Tax disputes begin in the administrative and tax courts, may be appealed to the Central Administrative Courts and can ultimately reach the Supreme Administrative Court, with the Constitutional Court reviewing constitutionality separately.
Representation requires a Bar-registered lawyer
Only lawyers registered with the Ordem dos Advogados may perform the acts reserved to the profession. Under Article 40 of the Civil Procedure Code, representation is mandatory in actions and appeals above the first-instance threshold of €5,000, and always before the Courts of Appeal and the Supreme Court. Acting without registration is ‘procuradoria ilícita’, a criminal offence under Law 49/2004.
Written codes govern the outcome; case law guides interpretation
Portuguese courts apply comprehensive written codes such as the Civil Code and the Civil Procedure Code rather than binding precedent. Supreme Court judgments, and above all uniformisation rulings (acórdãos de uniformização de jurisprudência), guide how the law is read. Your lawyer’s argument therefore rests on the wording of the statute and on how the higher courts have interpreted it.
Court fees are calculated in a unit of account
Court costs are governed by the Regulamento das Custas Processuais and expressed in Unidade de Conta (UC), a unit of account updated annually in line with the social support index. The taxa de justiça reflects the value and complexity of the case, and a remanescente may be charged above €275,000. As a rule the losing party bears the costs, while lawyers’ fees are freely agreed.
Property transactions carry notarial and registry formalities
Rights over immovable property are registered at the Land Registry (Registo Predial), which provides publicity and, for certain facts, a presumption of accuracy and protection against third parties. Transfers and encumbrances are normally formalised by public deed or by authenticated private document, and the acquisition is completed by registration. This matters whenever a Portuguese property is sold, gifted or inherited.
Legal aid can cover the cost of a lawyer
The regime of access to law and the courts under Law 34/2004 grants legal aid to natural and legal persons who demonstrate economic insufficiency, assessed by the Social Security Institute. It may include exemption from the court fee and other charges, the appointment and payment of a lawyer, phased payment of fees and the appointment of an enforcement agent.
Key time limit — Tax Law
Inheritance and stamp duty reporting after a death — By the end of the 3rd month after death. The reporting duty to the tax authority applies even where the heirs are exempt.

Common situations
Why these cases become complicated
Most people who contact us are not looking for a theoretical answer. They have a document in front of them, a date approaching, or a decision they do not understand.
An assessment you did not expect
You sold a Portuguese property, received a notice from the tax authority and now have a limited window to react. Without a clear reading of the file, it is hard to tell whether the figure is correct or open to challenge.
Advice from the wrong professional
Tax and property matters sit before a specialised branch of the Portuguese courts. An adviser who is not registered with the Ordem dos Advogados cannot perform the acts reserved to lawyers, including representation in proceedings.
Deadlines that pass quietly
The three-month period for challenging an administrative act, and shorter civil periods of six months or two years, can expire before you realise a decision existed. Once a deadline has run, the available options narrow considerably.
How matching helps
What working with a matched lawyer looks like
We are not a law firm. Our role is to understand your situation and put it in front of lawyers who work on Portuguese tax and property files.
You describe the case once
Tell us about the asset, where you live, the notices you have received and what you want to achieve. We pass a structured summary to lawyers, so the first conversation starts with your facts rather than with basic questions.
Matched with Portuguese tax and property lawyers
We look for lawyers whose practice covers Portuguese tax and property matters and who are registered with the Ordem dos Advogados, as Portuguese law requires for the acts reserved to the profession.
Clear information before you commit
You can compare scope, approach and fee structure before appointing anyone. Portuguese lawyers’ fees are freely agreed, so you are free to ask for a written agreement setting out what the fee covers.
Support beyond a single question
If the matter goes further, the same lawyer can follow the file before the administrative and tax courts and, where appropriate, on appeal to the Central Administrative Courts or the Supreme Administrative Court.
Cross-border matters
Portuguese tax questions rarely stay inside Portugal
Owners, expatriates, heirs and investors often deal with a Portuguese asset while living elsewhere, or with tax authorities in more than one country. We match clients from across Europe and beyond with lawyers who understand that the Portuguese side of the file has its own courts, formalities and deadlines.
Frequently asked
Questions about Portuguese tax and property matters
Do I need a capital gains tax lawyer in Portugal if I have sold a Portuguese property?
If you have received an assessment, a query or a penalty notice from the Portuguese tax authority, a lawyer can review how the transaction was reported and how the gain was calculated. Lawyers registered with the Ordem dos Advogados may represent you before the administrative and tax courts. A first review often shows whether a challenge is worth pursuing.
Which courts deal with Portuguese tax disputes?
Tax matters fall to the administrative and tax courts, which are separate from the ordinary judicial courts under Articles 209 et seq. of the Constitution. Decisions can be appealed to the Central Administrative Courts and ultimately to the Supreme Administrative Court. The Constitutional Court reviews the constitutionality of legislation outside that ordinary structure.
Can a lawyer from another EU country represent me in Portugal?
EU lawyers may register with the Ordem dos Advogados and establish in Portugal under their home professional title, or seek full admission after an aptitude exam. Performing the acts reserved to lawyers without Bar registration is unlawful practice (‘procuradoria ilícita’) and is a criminal offence under Law 49/2004.
How are lawyers’ fees set in Portugal?
Portuguese lawyers’ fees are freely agreed with the client; there are no binding official tariffs. Fees may be fixed by written agreement (honorários acordados) or, failing that, assessed according to complexity, time and responsibility involved. If you succeed, the losing party may be ordered to reimburse your party costs within certain limits.
How long do I have to challenge a tax or administrative decision?
A judicial challenge to an administrative act must generally be brought within three months. General civil limitation runs for 20 years, while periodic claims such as rent, interest and fees prescribe after five years, and some claims have much shorter periods of six months or two years. Deadlines are strict, so early advice matters.
What happens to a Portuguese property when the owner dies?
Portugal abolished inheritance and gift tax in 2004. Gratuitous transfers are now taxed through Stamp Duty at a single rate of 10%, but the spouse or de facto partner, descendants and ascendants are exempt. The estate must still be reported to the tax authority by the end of the third month after the death, and real property must be registered.
