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 on the same day, and Empresa Online, which does the same over the web for 220 euros with standard articles. On paper, either one makes the lawyer optional.

The catch, and the reason the "just hire someone" advice sticks, is that the online self-service route broke for me. I am an EU citizen here on the five-year residency certificate (the paper Certificado de Registo, not a chipped card), with no Portuguese Citizen Card (Cartão de Cidadão) and its built-in digital ID, and Empresa Online could not read my profile and failed without telling me 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 same-day promise of the in-person route, because my solicitadora filed online and the filing sat in the registry's queue. 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). At Empresa na Hora you can name one at the counter.
3. Abertura de atividade at the tax authority, within 15 days of the company being presented for registration.
4. RCBE beneficial-owner declaration, within 30 days of the company's registration (founders can file it during Empresa na Hora or Empresa Online).
5. Social Security for the gerente: Segurança Social enrols you from the registry's own notice; the company answers its requests and reports changes.
6. Open a business bank account.

After Step 3, with certified invoicing software and an invoice series communicated to AT, you can start invoicing. Steps 4 and 5 still carry deadlines with real consequences, 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 will normally already have one. New to it? See NIF.
• Digital authentication: a Chave Móvel Digital (CMD) or a Cartão de Cidadão. This is where my trouble started. My CMD, linked to a foreign passport, carried an incomplete government profile, and the systems that read that profile (the online company registry, and later a bank's online onboarding) rejected it. Hold this thought, it explains most of what broke 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.
• Share capital: the amount you set in the articles. At Empresa na Hora you can deposit it in the company's account beforehand, within 5 working days after, or declare that it will be delivered to the company by the end of its first financial year.
• A fiscal address in Portugal for the company's registered seat.
• Your CAE codes (activity classification, CAE-Rev.4 since 2025). The registry assigns a company's codes from its stated business purpose (objeto social) when it is formed, so decide the activities now and make sure the objeto social covers them.

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: without a Cartão de Cidadão, Empresa Online did not work for me (it authenticates against a digital profile mine lacked), while Empresa na Hora stays open because it is in person with physical ID, and the constraint is getting an appointment. And there is a second axis that mattered more than which ID I held: my solicitadora's online filing still sat in the IRN's queue for weeks, while the in-person counter constitutes the company in one visit. That is why a solicitador cleared the online wall for me but did not make it fast.

Empresa na Hora, in person, 360 euros, and genuinely "on the spot". You book a slot and go to an Empresa na Hora counter with every partner present. You choose a name (from the pre-approved list, or your own name already cleared with a Certificado de Admissibilidade) and one of the pre-approved sets of articles, and the articles are signed and the company registered in that visit. When it is done you get the articles, the access code to the permanent commercial certificate (certidão permanente), the access code to the company card with its NIPC, and the company's Social Security number. You also name your contabilista certificado there, or file the início de atividade at a tax office within 15 days. A passport or a residence permit is accepted as ID alongside the Cartão de Cidadão, so you do not need a citizen card for the in-person route, and you do not need a CMD either. That is the whole difference from Empresa Online: there the wall was digital identity, here it is simply getting a slot.

I looked up slots through SIGA, the appointment system, 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. You can use any Empresa na Hora counter, whatever the location of the company's future seat, 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 looks structural, not a passing blip. In 2026 Observador reported the registries short of 270 registrars (conservadores) and 2,731 registry officers, the latter 55 percent of the planned headcount. A backlog like that is, as far as I can tell, 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. It is also the one that broke for me. Empresa Online 2.0 would not take my CMD, tied to a foreign passport with an incomplete profile, the way it takes a Cartão de Cidadão. The form would not authenticate me through, with no message explaining why. It did not work for me without a citizen card.

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 completed for me. 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 did not clear was the IRN backlog: the online filing still sat in the queue, so it took about six weeks (31 March to the 15 May NIPC, with the name approval inside that window). As I see it, the real split is online versus in person, not paid versus DIY. I was also 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, a passport or residence permit 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 appointment 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, you named a CC there or have 15 days to file the abertura de atividade yourself. 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.

What the CC does: takes technical responsibility for the company's accounts under the Portuguese accounting standard (SNC), and signs and files its tax returns (IRC Modelo 22, the annual IES, and the periodic IVA). The day-to-day bookkeeping can be done by you or by software; the responsibility and the signature are what only a CC can give. 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 I was quoted 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, and it comes before your first invoice. The deadline is 15 days from the date the company is presented for registration at the commercial registry (CIRC Art. 118.º), and in practice your CC files it through their own access (per Step 2). If you formed through Empresa na Hora, you named a CC at the counter or file it at a tax office within those 15 days.

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. EU business clients and foreign software purchases do not take you out of Article 53, but they bring reverse-charge obligations from the first invoice, so the exemption saves less paperwork than it sounds.
• CAE codes: your activity classification (for example 62100, atividades de programação informática, for software development). A company holds CAE codes only, assigned by the registry from its objeto social at formation. Check them at the abertura: a code for an activity already in the objeto social can be added at AT with a declaração de alterações, while a new activity needs the objeto social changed first. They record your registered scope. Under simplificado the coefficient follows the activity you actually carry on, and whether it is specifically listed in the Art. 151 CIRS table (the catch-all outros prestadores de serviços does not count), not the code alone.
• Intra-EU services and Plenos Poderes: the box for Prestação/Aquisição de Serviços Intracomunitários, which you tick before supplying services to, or buying services from, businesses in other EU countries, 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 held personally that is just you, so the content is trivial, but the deadline is strict: the initial declaration is due within 30 days of the company's registration (registo de constituição).

Founders who incorporate through Empresa na Hora or Empresa Online can file it as part of that procedure, but it is not automatic, so check whether yours is on file rather than assuming it was done. Otherwise it is filed online through the RCBE website. It does not have to be you: the RCBE rules let a solicitador, lawyer, notary or contabilista certificado file it for the company (my solicitadora registered mine).

The part people forget is ongoing: the RCBE must be confirmed by 31 December each year (a confirmação anual), unless you already updated it earlier that year and nothing has changed since. Any change in beneficial ownership is declared within 30 days. While the declaration is missing or out of date, the company may not distribute profits, contract with the State, or receive European or public funds, and the non-compliance is published on the RCBE website. Separately, a company that fails its duty to keep its own register of beneficial owners up to date can be fined 1,000 to 50,000 euros. Put the annual confirmation on a recurring reminder.

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

You do not register yourself as gerente. Under Segurança Social's own guide for members of statutory bodies (Guia Prático 1008), the commercial registry communicates the gerente's appointment to Segurança Social automatically, and Segurança Social then enrols you. What falls on the company is the follow-up: when Segurança Social asks, it sends a copy of the articles of association (pacto social) and the minutes (ata) naming the gerentes, within the short deadline the request gives, and it reports any later start, cessation, suspension or other change. Segurança Social's guide does not tie any of this to the activity start on your abertura at the tax office.

What you then owe depends on your situation. A gerente contributes on what the company pays them, with a minimum base of one IAS, so even a zero salary carries a monthly contribution. The usual way out for a founder is narrow: a gerente who receives no remuneration of any kind, and has another activity under a mandatory regime (an existing trabalhador independente registration, for example) earning more than one IAS, is excluded from the gerente regime altogether. Draw any salary and that exclusion ends. Whether you clear it is a question for your contabilista certificado, and Part 4 works through it from my own case.

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. The Portuguese banks I tried offer online account opening, but their onboarding read the same government digital profile and rejected my CMD tied to a foreign passport, so online corporate onboarding was not available to me. That left a physical branch visit with the company documents.

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 I hit: I could not pay Portuguese Multibanco charges (entidade / referência) from Revolut Business. Check which payment methods each AT and Segurança Social payment document offers before you rely on an account without Multibanco; a Portuguese account is the backstop for a Multibanco-only charge.

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.
• Periodic IVA returns on the normal VAT regime (quarterly or monthly, by the VAT cadence set at abertura).
• Sócio-gerente Social Security (monthly), unless you are excluded as an unpaid gerente (Step 5).
• RCBE annual confirmation by 31 December, unless you updated it earlier that year (Step 4).
• Accounting kept continuously, under the CC's technical responsibility.

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: a Certificado de Admissibilidade from the RNPC, optional.
• Solicitador, if you use one: around 250 euros in my case.
• Share capital: whatever you set in the articles.

Recurring: a contabilista certificado (I was quoted roughly 100 to 150 euros a month early on), plus Social Security for the gerente unless you are excluded. 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 in mid-June 2026), or weeks via a solicitador in the registry backlog, as in my case.

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 with a passport or residence permit; do not default to a slow solicitador without checking SIGA across districts.
• Booking only your own city. In mid-June 2026 the largest districts ran roughly two months out. A smaller district can be next-day, and any counter can register your company.
• Mixing identity documents. Use the same ID at every step (Step 1).
• Missing the date-driven clocks. The RCBE initial declaration runs 30 days from the company's registration, and the annual confirmation is due by 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 (or named at the Empresa na Hora counter)
• Abertura de atividade filed within 15 days of the company being presented for registration: IRC regime, VAT regime, CAE codes checked, intra-EU services box ticked if needed
• RCBE on file, within 30 days of the company's registration (check whether the founders filed it at incorporation)
• Social Security enrolment as gerente confirmed, and any request for the pacto social and ata answered promptly
• Business bank account open
• Plenos Poderes decision made, after your CC engagement is in writing
• Recurring reminders set: IVA periods, IRC Modelo 22, IES (15 July), and the RCBE annual confirmation (31 December)
