For UK nationals in Portugal, Brexit made the paperwork much more important. The first question is simple: were you already living legally in Portugal before 1 January 2021, or did you arrive after that?
That date changes the conversation. Some people are covered by the Withdrawal Agreement. Others need to use the normal non-EU residence routes. If someone gives advice without asking when you moved, be careful.
If you were here before 1 January 2021
GOV.UK says that if you moved to Portugal before 1 January 2021 and have been legally living here since then, you and your family members have rights under the Withdrawal Agreement.
You should have a Withdrawal Agreement residence permit. GOV.UK says that after five years of residence, you can apply for a permanent residence card valid for 10 years.
If you were living in Portugal before 1 January 2021 and still do not have the Withdrawal Agreement residence card, GOV.UK says you must get one now and contact AIMA at brexit@aima.gov.pt with the right documents proving your time in Portugal.
Use AIMA for the Brexit process
AIMA has a Brexit section for UK nationals and family members living in Portugal. It also lists the Brexit phone line and the email address for questions about the Withdrawal Agreement.
AIMA says supporting documents for regularisation may include a valid passport, bank statements showing transactions in Portugal during the relevant period, employment or service contracts, IRS returns or tax assessments, pension-payment proof with a Portuguese tax address, or proof of school attendance in Portugal, depending on the situation.
Do not send random documents without understanding what they prove. The point is to show the right link to Portugal at the right time.
Check your residence document
Look at your residence document now, not when you are about to travel.
Check:
- Name spelling.
- Date of birth.
- Nationality.
- Address.
- Expiry date.
- Whether it is temporary or permanent.
- Whether AIMA has your correct contact details.
Residence documents are boring until the day a bank, airline, school, health centre or border officer wants to see one.
If you arrived after Brexit
If you moved to Portugal after the Withdrawal Agreement period, you usually need a normal non-EU basis for residence. That might be work, study, family, passive income, remote work or another valid route.
Wanting to live in Porto is not an immigration category by itself. Check AIMA, the consulate and the current visa route before making plans around a move.
Gov.pt also warns that some migration information may be outdated after SEF was replaced by AIMA, so use AIMA for the latest residence-process information.
Healthcare
GOV.UK says that if you are registered as a resident in Portugal, you should register with the Portuguese national health service, SNS, and you will have the same rights to treatment as a Portuguese citizen.
For SNS registration, GOV.UK says you normally need to show your residence certificate, passport and NIF at your local health centre.
If you receive a UK State Pension or certain exportable benefits, you may be entitled to UK-funded healthcare through an S1. If you live in Portugal, do not assume a UK GHIC or EHIC works like it did for holidays. GOV.UK says residents cannot use a UK-issued EHIC or GHIC for healthcare unless they meet specific criteria, such as students, S1 pensioners or frontier workers.
Working
GOV.UK says you do not need a work permit or visa if you have been living legally in Portugal since before 1 January 2021, because of Withdrawal Agreement rights.
If you arrived later, check your own route. A visa, residence permit, student status or remote-work setup may not allow every type of work.
Driving licence
GOV.UK says that if you have a UK or Gibraltar driving licence and are a registered resident in Portugal, you can drive with it until it expires.
It also says that if your licence was issued in Jersey, Guernsey or the Isle of Man and you are a registered resident, you should exchange it for a Portuguese one.
Do not rely on old Brexit driving advice. Check IMT if your licence, age, vehicle or residence situation is unusual.
Tax and pensions
Living in Portugal can affect UK tax, Portuguese tax, pensions, savings and reporting obligations.
Keep records of:
- Date you became resident in Portugal.
- UK and Portuguese tax correspondence.
- Pension statements.
- Income sources.
- Bank accounts.
- NIF, NISS and SNS numbers.
- S1 documents, if relevant.
GOV.UK says the UK has a double taxation agreement with Portugal so you do not pay tax on the same income in both countries. That does not mean you can ignore tax filing. It means you need to understand which country taxes what.
Family members
Family rules depend heavily on whether the UK national is covered by the Withdrawal Agreement, whether the family member was already here, and the relationship.
Do not assume family reunification is automatic. Check AIMA and GOV.UK for your exact family situation, especially for spouses, partners, children, adult dependants or family members arriving later.
My take
If you are a UK national in Porto, keep your paperwork boring and current. Residence card, passport, NIF, SNS number, NISS if you have one, address, tax records, pension papers and health documents should all be easy to find.
The biggest mistake is living here as if Brexit paperwork will sort itself out later. It usually does not. Check the date you arrived, check whether Withdrawal Agreement rights apply, and keep AIMA/GOV.UK as your starting point.
