Incorporation itself is fast and cheap by European standards. But UK founders run into extra friction that Portuguese or EU nationals simply don't face: getting a tax number (NIF), passing enhanced banking checks, and working out whether their move triggers Portuguese tax residency.
This guide walks through the exact steps, costs, common pitfalls, and where bringing in specialist support makes sense.
TL;DR
- Lda: at least two partners, €1 minimum quota each; Sociedade Unipessoal (one person): €1 total
- UK founders incorporate via Empresa Online (remote) or Empresa na Hora (in person) in 1–3 weeks once documents are ready
- IRC: 19% mainland, 13.3% Madeira and the Azores; qualifying SMEs pay 15%/10.5% on the first €50,000
- 2025 UK–Portugal double tax treaty is in force on dividends, royalties, and business profits
- Biggest blockers for UK founders: NIF as a non-EU resident, and a Portuguese business bank account
Step-by-Step: Setting Up an Lda From the UK
Step 1: Obtain a Portuguese Tax Number (NIF)
Every shareholder and director needs a NIF from the Autoridade Tributária before incorporation can move forward. It is Portugal’s tax identification number, roughly equivalent to a UK Unique Taxpayer Reference (UTR).
Since Brexit, UK residents can no longer self-apply for a NIF in the same way EU, Norwegian, Icelandic, or Liechtenstein residents can. Where you have an existing tax relationship with Portugal, you'll generally need to appoint a Portuguese fiscal representative to submit the request on your behalf, unless you opt into electronic notifications instead.
You'll typically need:
- A valid passport
- Proof of UK address
- Written authorisation for your fiscal representative
There's no official published turnaround time for NIF processing. This is exactly where delays creep in if your representative isn't properly authorised, so confirm their credentials before you start.
Step 2: Choose and Reserve a Company Name
Submit your proposed company names to the Conservatória do Registo Comercial (Companies Registry) for approval. Names are checked against the RNPC database of existing companies and trademarks.
You can either pick from a list of pre-approved names on the Empresa Online portal (faster) or request a bespoke Certificate of Admissibility, which stays valid for three months.
Step 3: Draft and Sign the Articles of Association (Pacto Social)
The pacto social sets out:
- Who the partners are
- The company type
- Share capital and how it's split
- The registered office
- The business activity (object)
As a UK-based founder, you don't need to fly to Portugal for this. Signing via power of attorney is standard practice, and Portuguese authorities waive signature certification when the POA is issued to an identified lawyer or solicitor.
Step 4: Open a Bank Account and Deposit Share Capital
The minimum quota is technically €1, though most businesses deposit more for practical credibility with suppliers and clients. Capital is normally due within five working days of incorporation, subject to some exceptions.
This is where UK applicants hit friction. Portuguese banks apply enhanced anti-money-laundering (AML) and know-your-customer checks on non-EU applicants, covering:
- Entity name, business activity, and registered office
- Identity of directors and key management
- Anyone holding 5% or more of the company
- The purpose of the account and ongoing transaction monitoring
- Verification of any power of attorney used
Physical presence isn't a legal requirement, but banks don't universally guarantee remote onboarding. Budget extra time here compared to what an EU national would face.
Step 5: Complete Registration, VAT, and Social Security
Registration happens either online via Empresa Online or in person at an Empresa na Hora counter, which also issues your Social Security number on the spot. You'll receive a certificate of incorporation once this is done.
Two things founders often forget:
- Commencement-of-activity declaration: must be filed with the Finance authority within 15 days, with a certified accountant
- Beneficial ownership filing (RCBE): mandatory, free, and due within 30 days of incorporation
VAT registration isn't automatic for every Lda; it depends on your specific business activity, so confirm your obligation with the AT rather than assuming.
Navigating fiscal representation, banking KYC, and registration as separate processes is where most delays happen for UK founders unfamiliar with Portuguese bureaucracy. Firms with cross-border entity-formation experience, such as VJM Global, can help coordinate these moving parts so nothing stalls between the NIF stage and final registration.
When Should a UK Founder Set Up an Lda in Portugal?
An Lda makes sense if you need:
- A genuine trading presence inside the EU post-Brexit
- Eligibility for local incentives (Madeira's reduced tax rate, for example)
- A registered entity to support a Digital Nomad or Golden Visa application
It's less suitable if you're a UK company that just wants to invoice a handful of EU clients occasionally. In that case, the EU's One Stop Shop VAT mechanism may cover your needs without the overhead of a full Portuguese entity.
What You Need Before Incorporating From the UK
UK founders face more preparation than EU nationals mainly because Brexit ended self-service NIF applications for non-residents.
Documentation & Representation
- Valid passport and proof of UK address
- A Portuguese fiscal representative to handle your NIF (tax ID) application
Capital & Banking
- Minimum share capital ready (from €1, though most founders deposit more)
- Extra time and paperwork for enhanced bank KYC checks as a non-resident
Local Presence
- A registered office address in Portugal (a virtual office is acceptable)
- A local director or nominee if you want simpler day-to-day compliance
Key Parameters That Affect Your Setup
| Factor | Lda | SA (comparison) |
|---|---|---|
| Minimum shareholders | 1 (single-member SUQ) or 2 | Usually 5 |
| Minimum capital | €1 per quota | €50,000 |
| Complexity | Low | High |
A few decisions shape cost and timeline more than anything else:
- Legal structure: Choose an Lda for low capital and simple ownership; most UK founders skip the SA’s five-shareholder, €50,000 bar
- Region of incorporation: Mainland Portugal taxes profits at 19%; Madeira and the Azores charge 13.3%, with extra SME relief on the first €50,000
- UK–Portugal Double Taxation Agreement: Sets how dividends, royalties, and repatriated profits are taxed, and what relief you can claim in the UK
- Registration method: Remote filing via Empresa Online is usually faster for UK founders than an in-person Empresa na Hora appointment
Common Mistakes and Troubleshooting Tips
- Underestimating NIF timing: there is no official processing standard, and a poorly authorised fiscal representative can add weeks—verify credentials before you commit.
- Assuming UK tax residency is unaffected: more than 183 days in Portugal in any 12-month period (even non-consecutive) can trigger Portuguese tax residency, so check the treaty day-count rules before you relocate.
- Underestimating banking timelines: pre-arrange certified documents and expect extra AML scrutiny as a non-EU applicant.
- Skipping VAT or Social Security registration: an incorporated company that has not completed these filings is registered but not operational—file both promptly after incorporation.
Alternatives to Direct Lda Incorporation
Not every UK founder needs a full Portuguese Lda on day one. These lighter routes can bridge market testing, speed, or hands-off compliance.
- UK branch or representative office: Suits founders testing the market without committing capital. No separate legal personality means liability sits with the UK parent; file within two months of the parent’s resolution.
- Ready-made/shelf company: Faster path to a trading entity, with limited customisation and usually a higher cost than starting fresh.
- Cross-border business services firm: Fits founders who prefer a service fee over compliance risk. VJM Global supports entity formation, tax registration, and banking coordination for UK businesses expanding abroad.
Frequently Asked Questions
Can I live in Portugal and work remotely for a UK company?
Generally, yes, via a Digital Nomad Visa. But spending significant time in Portugal can trigger Portuguese tax residency separately from any decision to incorporate an Lda, so check the 183-day rule carefully.
Do the UK and Portugal have a double taxation agreement?
Yes. A new convention took effect in 2025, preventing UK founders from being taxed twice on the same income, including dividends, royalties, and business profits.
How long does it take to register an Lda in Portugal from the UK?
Roughly 1-3 weeks if your NIF and banking are pre-arranged. Delays almost always stem from NIF processing or bank onboarding, not the registry itself.
What is the minimum share capital for a Portuguese Lda?
As little as €1 per quota, though most founders deposit more for practical and credibility reasons with suppliers and banks.
Do I need to visit Portugal to set up the company?
No. Most steps, including signing the pacto social, can be completed remotely through a power of attorney and a fiscal representative.
Can a UK citizen be the sole director and shareholder of a Portuguese Lda?
Yes. There's no restriction on foreign ownership, provided you've obtained a valid NIF beforehand.
