Buying property in Lisbon and spending significant time here raises a question that is easy to ignore until it is urgent: when do you become a Portuguese tax resident, and what does that mean for your finances?
This is a topic where the details matter and where the rules have changed significantly in recent years. This guide gives you the framework — but given the individual complexity, professional tax advice is always worthwhile before you make decisions.
When do you become a Portuguese tax resident?
You become a Portuguese tax resident if either of the following applies:
- You spend 183 or more days in Portugal in a calendar year (days do not need to be consecutive)
- Your habitual residence is in Portugal — meaning you have a home in Portugal that you maintain as your principal place of abode, even if you spend fewer than 183 days there
This second test catches buyers who intend to keep their primary home abroad but spend substantial time at a Portuguese property. The test is applied on a facts-and-circumstances basis.
If you are a non-resident: You are taxed in Portugal only on Portuguese-source income (rental income, capital gains on Portuguese property, etc.)
If you are a tax resident: You are taxed in Portugal on your worldwide income.
Portugal’s double taxation agreements
Portugal has double taxation agreements (DTAs) with most major countries, including the UK, USA, France, Germany, Ireland, Canada and Australia. These agreements determine which country has the right to tax different types of income and prevent you from being taxed twice on the same income.
The specifics depend on your nationality, the type of income and the countries involved. Your tax adviser will need to review the relevant DTA for your situation.
The IFICI regime — Portugal’s new preferential tax regime
Until the end of 2023, Portugal offered a programme called the NHR (Non-Habitual Resident) regime — a 10-year preferential tax regime for new tax residents that offered, among other things, a flat 20% rate on Portuguese-source qualifying income and a 10% flat rate on foreign pension income.
NHR is now closed to new applicants (applications after 31 December 2023).
In its place, Portugal introduced the IFICI (Incentivo Fiscal à Investigação Científica e Inovação) regime, sometimes called NHR 2.0. This is significantly more targeted than the original NHR:
Who can apply for IFICI?
IFICI is available to individuals who:
- Are new tax residents in Portugal (not been resident in the previous 5 years)
- Work in one of the qualifying activity categories
Qualifying activities include:
- Scientific research and innovation
- Jobs in technology startups and the tech sector
- Higher education and scientific research at recognised institutions
- Roles in Portuguese-regulated special economic zones (including Madeira)
- Activities generating highly qualified income in designated sectors
Unlike the original NHR, IFICI is not available to retirees, remote workers in non-qualifying sectors, or general high-net-worth individuals relocating to Portugal. If you were planning to use NHR for pension income or passive income, that option is gone.
IFICI tax rates
For qualifying income earned in Portugal: flat 20% rate for 10 years.
Foreign income: generally taxed at standard Portuguese rates (the previous NHR exemption on foreign-source income no longer applies in the same way for most categories).
Implications for common buyer profiles
UK retirees and pensioners
The UK-Portugal DTA determines how UK pension income is treated. State pensions and most private pensions are taxable in the UK (with a credit for Portuguese tax). The NHR flat-rate pension treatment is no longer available. Get specialist advice before moving.
US citizens
The US taxes its citizens on worldwide income regardless of where they live. This creates complexity when you add Portuguese residency. The US-Portugal DTA helps, but American buyers should work with a dual-qualified US/Portuguese tax adviser from the start.
French residents
France-Portugal tax arrangements have changed in recent years. French retirees who previously benefited from NHR now face different treatment. French buyers should seek specific advice.
Remote workers (non-qualifying sectors)
If you work remotely for a non-Portuguese employer and your work does not fall within IFICI’s qualifying categories, you are taxed on that employment income at standard Portuguese progressive rates (up to 48%). The Portugal Digital Nomad Visa (D8) gives you the right to stay but does not provide a tax preference.
What happens to your home country tax residency?
Becoming a Portuguese tax resident typically means ceasing to be a tax resident in your home country — but this is not automatic and the rules vary significantly. In the UK, for example, you need to meet the Statutory Residence Test conditions to establish non-UK residence. In France, the tax residency test has multiple limbs.
This must be planned carefully. If you remain a tax resident in both countries simultaneously, you face potential double taxation that the DTA will only partially resolve.
When to get advice
Ideally, before you buy — or at the very latest, before you spend your first 183-day period in Portugal. The steps to take are:
- Establish your current tax residency status and what it will take to change it
- Model the tax implications of Portuguese residency on your income streams
- Understand whether IFICI applies to you
- Plan the timing of your move to optimise your position
