Setting Up an Lda in Portugal: The Complete Guide

If you are a foreigner forming a company in Portugal, the customary advice is to hand it to a lawyer or a solicitador and pay to make it disappear. Almost everyone does.

What nobody tells you is that you do not have to. The Portuguese State built two systems so you would not need to: Empresa na Hora, which registers a company in person in about an hour, and Empresa Online, which does the same over the web for a minimal fee. For someone with a Portuguese Citizen Card (Cartão de Cidadão) the online one is fast and cheap and makes the lawyer optional.

The catch, and the reason the "just hire someone" advice sticks, is that the online self-service route is currently broken for residents without that card. If you are an EU citizen here on the five-year residency certificate (the paper Certificado de Registo, not a chipped card), or any resident without a citizen card and its built-in digital ID, Empresa Online cannot read you and fails without telling you why. I hit exactly that wall.

So I ended up where the customary advice points anyway: a solicitador. The whole thing still took about two months, against the one hour the system advertises, because the usual paid route files online, into the same backlog as everyone else. This guide is so you walk in with your eyes open, whichever path you take: every stage from company name to your first legal invoice, in the order you actually hit them, what each step quietly locks in, and where the system breaks.

This is the hub. Each step links to a deeper write-up: the Bootstrapping a Startup in Portugal series for the real decisions and numbers, and the Registering a Company in Portugal series for the formation saga in full.

Lda or sole trader first?

This guide assumes you have decided on an Lda. If you have not, that is its own decision: a sole trader (trabalhador independente) is simpler and cheaper to run, while an Lda gives you limited liability and a sellable, investable entity. Most people starting out are better off as a sole trader. The trade-offs (liability, tax, cost, overhead) are covered in Part 2 of the Bootstrapping series.

The process at a glance

The whole path, in order. Each step has its own section below.

1. Form the company and get the NIPC (Empresa na Hora, Empresa Online, or a solicitador).
2. Appoint a contabilista certificado (CC), within 15 days of the NIPC.
3. Abertura de atividade at the tax authority (already done at the counter if you used Empresa na Hora).
4. RCBE beneficial-owner registry, within 30 days (often captured automatically at incorporation).
5. Register with Social Security as sócio-gerente, within 10 working days of your activity start.
6. Open a business bank account.

After Step 3 you can legally invoice. Steps 4 to 6 still carry hard deadlines and fines, so do not stop at "I can invoice now".

Before you start

Have these in hand. They apply whichever route you take.

• NIF (Número de Identificação Fiscal, your tax number). As a resident you already have one. New to it? See NIF.
• Digital authentication: a Chave Móvel Digital (CMD) or a Cartão de Cidadão. This is where the trouble starts. A CMD linked to a foreign passport carries an incomplete government profile, and the systems that read that profile (the online company registry, and later the banks) reject it. Hold this thought, it explains most of what breaks below.
• A company name: either pick a pre-approved name from the Empresa na Hora list (free, instant), or reserve a custom one with a Certificado de Admissibilidade de Firma from the RNPC (75 euros, or 150 rushed).
• Share capital: 1 euro minimum for a Unipessoal (a single quota). You declare it, it does not have to sit in an account first.
• A fiscal address in Portugal for the company's registered seat.
• Your CAE codes (activity classification). You formally set them at abertura de atividade, but decide them now.

Step 1: Form the company (and where each route breaks)

There are three ways to register an Lda. On paper each ends with a company and a NIPC (the company tax number). In practice the route that works depends on which ID you hold and how staffed your local registry (IRN) is. Here is each, with what actually happened to me.

Up front, so the rest makes sense: if you do not hold a Cartão de Cidadão, Empresa Online is effectively closed to you (it authenticates against a digital profile yours lacks), while Empresa na Hora stays open because it is in person with physical ID and is gated only by appointment availability. And there is a second axis that matters more than which ID you hold: every online filing, your own or a professional's, drops into the same manual IRN queue, and the in-person counter is the only route that skips it. That is why a solicitador clears the online wall but still does not make it fast.

Empresa na Hora, in person, 360 euros, and genuinely "on the spot". You book a slot, go to a Conservatória or Espaço Empresa, choose a name (either from the pre-approved list, or your own custom name already cleared with a Certificado de Admissibilidade), and walk out the same day with the company constituted, the NIPC issued, the company's Social Security number assigned, and the início de atividade already declared (bring your contabilista certificado's details so it can be signed at the counter). It is the one route that folds formation, abertura, and CAE coding into a single visit. Any formal photo ID works, an EU national ID card or a passport, so you do not need a Cartão de Cidadão for the in-person route. That is the whole difference from Empresa Online: there the wall is digital identity, here it is simply getting a slot. You do not need a CMD for the in-person route either; any formal ID is enough.

Slots are booked through SIGA, and availability is the entire game. A snapshot when I checked in mid-June 2026:

District (snapshot, mid-June 2026)	First Empresa na Hora slot
Viseu	next day
Évora	~1 month
Lisbon, Porto, Faro (largest districts)	~2 months

The lesson is the range, not the dates: the three largest districts cluster around two months, while smaller ones are near walk-in. Back in March 2026, when I actually needed it, the large districts had no slots at all, so the backlog is easing slowly, not gone. The appointment is not tied to your company's future address, so the fast play is to book the nearest district that actually has availability, even if you travel, and not assume your own city is representative.

Bring a Portuguese speaker. The smaller-town counters with the shortest queues are also the least likely to serve you in English. When I tried it in Lagos, the desk was Portuguese-only, and constituting a company is technical enough that getting through it on limited Portuguese is rough. If you do not speak it comfortably, bring someone who does: the trip where you save weeks on the queue is the same one where the language gap can stall you.

Why the registry is the bottleneck. This is structural, not a passing blip. As of mid-2026 the registry and notary service (IRN) was reported to be short more than 3,000 staff, including roughly 2,700 registry officers, a deficit near 55 percent, with backlogs specifically in dozens of commercial registry offices, the ones that incorporate companies (Observador). The union held a national strike in June 2026, and the State has been recruiting, but the shortfall is widely expected to take years, not months, to clear. This backlog is why even the solicitador route, the one I took, still sat in the queue for weeks. Measure any "one hour" or "few days" promise against the live SIGA data, not the brochure.

Empresa Online, web, 220 euros. The same registration online: 220 euros with a pre-approved set of articles (pacto social), or 360 for custom articles. It is the cheapest route and the one the State pushes. It is also the one that broke for me. Empresa Online 2.0 expects a complete digital identity, and a CMD tied to a foreign passport (incomplete profile) is not accepted the way a Cartão de Cidadão is. The form would not authenticate me through, with no message explaining why. It works with an actual citizen card; it did not work for me without one.

A solicitador filing for you. For an EU citizen without a Cartão de Cidadão whose nearest Empresa na Hora has no slots, this is the route that completes. My solicitadora filed through Empresa Online (the older system, not 2.0) on her own professional credentials, which clears the digital-identity wall. What it does not clear is the IRN backlog: any online filing lands in the same manual queue, so it still took about six weeks (31 March to the 15 May NIPC, with the name approval inside that window). The real split is online versus in person, not paid versus DIY. A professional can instead go in person for you with a power of attorney, which would skip the queue, but that is the expensive path: I was quoted up to 2,000 euros for full setup help, against 360 euros to do the in-person route myself. My own filing ran about 250 euros.

Use one identity document throughout. Whatever you start with (passport or national ID card), use the same one at every step: company-name approval, power of attorney, and filing. A mismatch between the passport I used for the name approval and the Swedish ID card on the power of attorney flagged a discrepancy and cost me an extra week.

What I would do differently: the fast route is Empresa na Hora, and it has nothing to do with which ID you hold. Because it is in person, any formal ID works, so the Cartão de Cidadão question does not even arise here, that is purely an Empresa Online problem. The only thing between you and a same-day company is a free SIGA slot. If you want speed, book the nearest district with availability, even if you have to travel, instead of the six-week solicitador wait I reached for partly because I wrongly assumed the in-person route was as closed to me as the online one. It was not.

Forming the company is the middle of the process, not the end. If you used Empresa na Hora, the next step (abertura de atividade) was already done at the counter. Otherwise it comes next, along with the contabilista certificado, RCBE, Social Security, and a bank account.

Step 2: Appoint a contabilista certificado

Every Lda must have a contabilista certificado (CC), a certified accountant registered with the OCC. This is not optional, and there is no DIY equivalent the way there is for a sole trader on the simplified regime: organized accounting (contabilidade organizada) legally requires a CC. Appoint one within 15 days of the NIPC.

What the CC does: keeps the company's books to the Portuguese accounting standard (SNC) and files its tax returns (IRC Modelo 22, the annual IES, and the periodic IVA), carrying technical responsibility for them. What they are not is an auditor: a Revisor Oficial de Contas (ROC) independently certifies the accounts and is only mandatory for larger companies. A small Lda needs a contabilista certificado, not a ROC.

Cost: at a low-volume early stage, expect roughly 100 to 150 euros a month, rising as payroll and turnover grow.

The credential trap. The CC acts for your company through the CC's own Portal das Finanças access, not your company password. If a CC asks for your company AT senha to do routine filings, that is the freelancer way of working applied to a company, and it is not needed. Separately, you choose whether to grant the CC Plenos Poderes Declarativos, the setting that lets them submit your declarations under their own credentials. Grant it, but only once you have a signed engagement, and with margin before your first filing deadline. The full reasoning is in Part 3.

Step 3: Abertura de atividade

Abertura de atividade is the single declaration at the tax authority (AT) that turns your legal company into a tax-paying entity. Until it is filed you cannot invoice; after it, you can. The deadline is 15 days from the company's legal publication (anúncio), and in practice your CC files it through their own access (per Step 2). If you formed through Empresa na Hora, this was already done at the counter.

In one form it locks in four things with consequences for years:

• IRC regime: regime geral (real profit, expenses deducted) or regime simplificado (a fixed coefficient on revenue). For a year-one company expecting a loss, geral is usually the safer default, and it applies automatically unless you opt into simplificado. Why this matters for software is the SaaS coefficient question.
• VAT regime: normal (periodic IVA returns) or the Article 53 exemption. Most companies invoicing EU clients or buying foreign software fall outside the exemption's reach from day one anyway.
• CAE codes: your activity classification (for example 62010 for software development), which drive the simplificado coefficient and your registered scope.
• REI/VIES and Plenos Poderes: the intra-EU operator register (needed if you trade with EU businesses) and the CC-filing setting from Step 2.

None of this is explained to you as the form goes in, which is the whole problem. The field-by-field walkthrough, the actual values I chose, and what I would do differently are in Part 3.

Step 4: RCBE (beneficial owner registry)

The RCBE (Registo Central do Beneficiário Efetivo) is the beneficial-owner registry, Portugal's slice of EU anti-money-laundering rules. It records who ultimately owns and controls the company. For a single-owner Unipessoal Lda that is just you, so the content is trivial, but the deadline is strict and the fine is not: the initial declaration is due within 30 days of the company being established, and non-compliance runs 1,000 to 50,000 euros.

Companies formed through Empresa na Hora or Empresa Online generally have the initial RCBE captured automatically at incorporation, so if you went that way, confirm whether yours was already done rather than assuming you still owe it. Otherwise it is filed at rcbe.justica.gov.pt, and in practice it is often done for you as part of formation (my solicitadora registered mine, and a CC can file it too).

The part people forget is ongoing: the RCBE must be confirmed every year by 31 December (a confirmação anual), even when nothing has changed, and updated within 30 days whenever beneficial ownership does change. Put the annual confirmation on a recurring reminder, since nobody prompts you and the fine is the same.

Step 5: Register with Social Security (as sócio-gerente)

Forming the company and opening activity does not register you with Social Security; that is a separate step with its own clock. As managing partner (sócio-gerente) you must register with Segurança Social within 10 working days of your declared activity start (the data de início de atividade on the abertura, not the company formation date). It is easy to miss because it is the one deadline that keys off the activity date, not the formation date.

What you then owe depends on your situation. A sócio-gerente is liable for a monthly Social Security contribution on a minimum base, even on a zero salary, unless it is waived. The usual route to a waiver is acumulação: if you already contribute above the minimum through another activity (for example an existing trabalhador independente registration), the gerente contribution can fall away under the Código Contributivo. Whether it applies to you is a question for your contabilista certificado, and the actual numbers are what Part 2 covers and the upcoming Part 4 works through in full.

Step 6: Open a business bank account

A company needs its own account, separate from your personal money, and this is where the incomplete-profile problem from "Before you start" resurfaces. Portuguese banks let residents open accounts online, but that onboarding authenticates against the same government digital profile, and a CMD tied to a foreign passport is rejected, so online corporate onboarding is not available to you. You are back to a physical branch visit with the company documents (the certidão, the NIPC, your ID, proof of address).

Faced with that, I made a different call: I use Revolut Business as the company's main account. Descodify is an online-first business, almost everything is card and transfer, so a traditional Portuguese branch relationship buys me little, and Revolut Business opens online without the branch friction.

One caveat to know: Revolut Business does not support Portuguese Multibanco, so you cannot pay entidade / referência (Multibanco) charges from it. For the obligations that matter this is no longer a blocker, because both AT and Social Security now accept payment by bank transfer to an IBAN (Segurança Social added a virtual-IBAN option on the payment document in 2025, see Como pagar), which Revolut handles. So IRC, IVA, and your monthly contributions are all coverable by transfer. A Portuguese account is then a backstop for the occasional Multibanco-only charge, not a requirement for the core filings.

Ongoing obligations

Once the company is running, your contabilista certificado handles most filings, but the obligations are yours. The recurring ones for a small Lda:

• IRC Modelo 22 (annual corporate income tax return) and the IES (annual accounting and statistical declaration), filed by the CC.
• Pagamentos por conta (IRC payments on account during the year, once the company is profitable).
• Periodic IVA returns (quarterly or monthly, by the VAT cadence set at abertura).
• Sócio-gerente Social Security (monthly), unless waived through acumulação.
• RCBE annual confirmation by 31 December (Step 4).
• Accounting kept continuously by the CC.

Exact deadlines shift year to year; the CC owns the calendar, but knowing the obligations exist is how you keep them honest.

Cost and timeline summary

One-off to form:

• Registration: 360 euros (Empresa na Hora) or 220 euros (Empresa Online, pre-approved articles).
• Custom company name: 75 euros (Certificado de Admissibilidade), optional.
• Solicitador, if you use one: a few hundred euros (around 250 in my case).
• Share capital: 1 euro minimum.

Recurring: a contabilista certificado, roughly 100 to 150 euros a month early on, plus Social Security for the gerente unless waived. Part 2 breaks down the real annual overhead.

Timeline: same-day with Empresa na Hora if you can get a slot (next-day to around two months out by district), or weeks via a solicitador because of the registry backlog.

Common pitfalls

• Assuming the online route is your only DIY option. If you lack a citizen card, Empresa na Hora in person is open to you and often faster; do not default to a slow solicitador without checking SIGA across districts.
• Booking only your own city. The largest districts run roughly two months out. A smaller district can be next-day, and you can register there.
• Mixing identity documents. Use the same ID at every step (Step 1).
• Missing the date-driven clocks. Social Security keys off your activity-start date (10 working days), and the RCBE annual confirmation is due every 31 December.
• Handing over your company AT password. Your CC works through their own access; grant Plenos Poderes instead, once the engagement is in writing.

Setup checklist

Everything in one place. The deadline-bearing items are flagged.

• Company formed, NIPC issued
• Contabilista certificado appointed, within 15 days of the NIPC
• Abertura de atividade filed: IRC regime, VAT regime, CAE codes, REI/VIES all set (done at the counter if you used Empresa na Hora)
• RCBE on file, within 30 days of establishment (check whether it was auto-captured at incorporation)
• Social Security registered as sócio-gerente, within 10 working days of your activity start
• Business bank account open
• Plenos Poderes decision made, after your CC engagement is in writing
• Recurring reminders set: IVA periods, IRC Modelo 22 (~May), IES (~July), and the RCBE annual confirmation (31 December)
