Starting a business in Portugal usually follows the same broad path: get a Portuguese tax number (NIF), choose whether to work as a self-employed person or set up a company, register with the tax authority and Social Security, open a business bank account and arrange your accounting. Much of it can now be started online, and the official ePortugal portal brings the public services together.
This guide walks through those practical first steps, what to have ready and what tends to take longer than people expect. It’s general information, not legal or tax advice: a qualified Portuguese lawyer or certified accountant should confirm the right route for your situation.
At a glance
- Who it’s for: newcomers and residents planning to sell services or products in Portugal.
- Main decision: self-employed (trabalhador independente) or a company (sociedade).
- Key official source: the ePortugal public services portal.
- Who confirms the details: a certified accountant (contabilista certificado) and, where needed, a lawyer.
Starting a business in Portugal: the usual steps
1. Get your NIF
The NIF (número de identificação fiscal) is your Portuguese tax number. You’ll need it for almost everything: renting, opening a bank account, signing contracts and registering any business activity. Our guide on what a NIF is and how newcomers get one covers the usual ways to apply.
2. Choose your structure
There are two broad routes, each with its own variations.
- Self-employed (trabalhador independente): you work in your own name and “open activity” (abrir atividade) with the tax authority. It’s generally quicker to set up and suits freelancers and consultants starting small. You are personally responsible for the business’s obligations.
- Company (sociedade): a separate legal entity, such as a private limited company. Setting one up takes more steps and ongoing formalities, but it separates the business from your personal affairs and can suit larger plans or partners.
This choice affects how you’re taxed, what you pay to Social Security and what accounting you need. It’s the decision most worth discussing with a certified accountant before you register anything.
3. Register the activity
If you’re self-employed, you register the start of your activity with the tax authority (Autoridade Tributária), usually through the Finanças online portal. You choose activity codes that describe what you do, and the details you enter affect how you’ll be taxed.
If you’re setting up a company, Portugal offers fast-track options, including registering in person through the “Empresa na Hora” service or online. The registration also covers getting the company’s own tax number. Check the current requirements on ePortugal before you start, as documents and conditions can change.
4. Sort out Social Security
Self-employed people and companies have Social Security obligations, and the rules for when contributions start and how they’re calculated depend on your situation. Ask your accountant to explain what applies to you and when.
5. Open a business bank account
Companies need their own account, and keeping business money separate is sensible even when you’re self-employed. Banks usually ask for your NIF, identification, proof of address and, for companies, the registration documents. Requirements vary between banks, so ask before your appointment.
6. Arrange accounting and invoicing
In Portugal, invoices must be issued through certified invoicing software or the tax authority’s own portal. Companies generally need a certified accountant to keep their accounts. Even when it isn’t required, having one from day one avoids costly mistakes with VAT, deadlines and declarations.
What to have ready
- Valid identification (passport or residence document) and your NIF.
- Proof of address in Portugal, where required.
- A clear description of what you’ll sell or do, to choose the right activity codes.
- For a company: a proposed name, the partners’ details and how the company will be run.
- Access to the online portals: the Finanças password and, if you have one, a Portuguese citizen card or digital mobile key, which make many online services easier.
- Contact details for a certified accountant before you register.
What usually takes longer than expected
- Getting the NIF and portal access, especially before you have a Portuguese address.
- Opening a bank account, as banks may ask for extra documents or several meetings.
- Understanding your tax and Social Security position, which depends on residency and personal circumstances.
- Licences for specific activities, such as food, health services or short-term rentals (Alojamento Local), which have their own rules.
- Language: many official services and documents are in Portuguese, so allow time or bring help.
Getting found once you’re set up
Once the paperwork is done, the next challenge is customers finding you. For a local business, the first step is usually a Google Business Profile, the free listing that appears on Google Maps. Our guide to getting your business on Google Maps explains how to create and verify one.
A simple website in the language your customers search in, with clear services, contact details and opening hours, does the rest of the groundwork. If you’d rather hand the digital side to someone who knows both Portugal and international markets, we help newcomers plan and set up their online presence, and we work in eight languages. You can see the services we offer. We don’t give legal or tax advice, so we’ll always point you to a lawyer or accountant for those questions.
Who should confirm the details
A certified accountant (contabilista certificado) is the right person for your structure, tax regime, VAT, Social Security and invoicing. A lawyer is the right person for company formation documents, partnership agreements, licences and anything to do with visas or residency. Speaking to them before you register usually saves time and money later.
Frequently asked questions
Can a foreigner start a business in Portugal?
Generally yes, but what you need depends on your nationality and residency status. Citizens of EU countries and non-EU nationals face different requirements, so check your own situation with a lawyer before you start.
Is it better to start a business in Portugal as self-employed or as a company?
Many people start self-employed because it’s simpler, then form a company as the business grows. The right answer depends on your expected income, risk and plans, which is why it’s worth a conversation with a certified accountant.
Can the whole process be done online?
Much of it can, especially once you have portal access and a digital signature method such as the citizen card or digital mobile key. Some steps, like opening a bank account, may still need an appointment.
Starting a business in Portugal is very doable with the right order of steps: NIF first, structure next, then registration, banking and accounting. Take the decisions that matter with a professional, and the rest falls into place.
