How to Start a Business in Portugal: Complete Step-by-Step Guide

Starting a business in Portugal involves more than completing the registration process. Before moving forward, it is important to define the activity, legal structure, responsibilities of the participants, tax framework, financial organisation and the resources required to begin operating.

For an entrepreneur, preparing these decisions in advance reduces the risk of having to correct processes or change important choices only a few months later. Recent business activity also highlights the relevance of the subject: by the end of November 2025, more than 49,000 companies had been incorporated in Portugal, according to Informa D&B.

This guide explains how to start a business in Portugal, which decisions should be made before registration, the main incorporation channels available and what should be organised so that the business begins with a solid foundation.

What should you define before moving forward?

Before incorporating the business, it is advisable to turn the idea into a reasonably structured project. A business plan helps estimate investment, fixed costs, cash flow requirements, pricing, margins and objectives. It can also help determine whether the activity should begin as a sole trader or through a company.

A company is a structure with its own responsibilities. You should define who will participate in the project, who will manage the business, where the registered office will be located, which activity will be carried out and how the startup phase will be financed.

The choice of company type should reflect the expected size of the business, the number of founders, the level of risk involved and the company’s growth objectives.

1. Choose the legal structure

The legal form of the company affects its ownership structure, the liability of its owners and the way the business is managed. This decision should not be based solely on how simple the process is or on the minimum amount required to begin.

Sole trader

A sole trader carries out the activity in their own name. This structure may be suitable for certain individual projects, but it should be assessed carefully in light of the liability associated with the activity.

Single-member private limited company

A single-member private limited company has a single shareholder, who may be either an individual or a legal entity. It is a common option when there is only one founder and the intention is to operate through a company.

Private limited company

A private limited company is used when there are two or more shareholders. The share capital is divided into quotas and management is normally assigned to one or more managers. It is a common structure for small and medium-sized enterprises.

Public limited company

A public limited company has a more complex structure and is generally considered for larger projects or businesses with specific capital and governance requirements.

The Portuguese Justice portal explains the characteristics of the main company types. If you intend to create a company with several participants, ownership interests, decision-making powers and shareholder responsibilities should be clearly defined.

2. Define the business activity and choose the CAE codes

The company’s economic activity must be correctly identified using the applicable CAE codes, Portugal’s official classification of economic activities. A company may have one main activity and, where necessary, additional secondary activities.

CAE Rev. 4 has been in force since 2025. Statistics Portugal (INE) provides a tool for consulting the classification of economic activities and states that the code used for legal purposes should be confirmed in the relevant official system.

An inaccurate choice may require later amendments or create inconsistencies between the actual activity, corporate purpose, licensing requirements and other legal or tax frameworks. The selected codes should therefore reflect what the business will actually do.

3. Choose the company name

It is possible to use a pre-approved company name or, in certain circumstances, a name generated from the participants’ names. If you require a specific company name that is not available among the existing options, it may be necessary to request a certificate of admissibility.

The certificate confirms that the intended name may be used and identifies elements such as the registered office, legal form and corporate purpose. It currently has a validity period of three months.

4. Define the share capital and articles of association

Share capital represents the amount subscribed by the shareholders for the company. Although some legal structures allow a very low minimum share capital, this amount should not be confused with the money actually required to launch and operate the business.

The company’s share capital should be considered together with its investment and cash flow requirements. Equipment, technology, premises, inventory, salaries, insurance and communication may require resources far above the amount formally registered as share capital.

The articles of association establish essential elements of the company, including its purpose, registered office, capital, owners and operating rules. Simplified incorporation procedures may use pre-approved articles of association. Where the project has specific requirements, a structure adapted to the business may be more appropriate.

Under the in-person incorporation procedure, official information provides for situations in which shareholders may declare that the subscribed capital will be deposited with the company by the end of the first financial year. The applicable conditions are explained by the Portuguese Justice service in its information on immediate company incorporation.

5. Choose between Empresa na Hora and Empresa Online

Once the main decisions have been made, the company can be incorporated through different channels provided by the Portuguese registration and notary services.

Empresa na Hora

The official Empresa na Hora service allows certain types of companies to be incorporated during a single appointment. The future shareholders attend an Empresa na Hora service desk in person with the required documentation.

Where the participants are individuals, a valid identification document is required. Where a legal entity participates, additional documentation concerning that entity and its representatives may be required.

According to the Portuguese Registry services, the standard application currently costs €360.

Empresa Online

A company can also be incorporated online. The platform allows the incorporation of eligible companies to be completed digitally, provided that the relevant authentication and documentation requirements are met.

Through the Empresa Online service, the standard cost is currently €220 when a pre-approved contract template is used and €360 when the document is drafted by the applicants. The official Empresa Online fees can be checked directly on the Portuguese Justice portal.

The digital channel reduces the need for in-person visits, but it does not replace the analysis required beforehand. Company incorporation should be based on a structure designed for the real activity rather than simply on the fastest available option.

6. Formalise the registration and start the activity

Once all the required elements have been prepared, the company can be formally registered. Registration legally establishes the company and provides the information required to proceed with the relevant tax and operational steps.

The declaration of commencement of activity is a key stage. It communicates information that influences the company’s tax framework, including its business activity and estimated turnover.

The Portuguese Tax Authority states that the declaration must be submitted before the activity begins and that, where formal organised accounting is mandatory or chosen, the submission must be made by a Certified Accountant.

At this stage, the company’s VAT framework is also defined according to the information provided and the conditions applicable to the activity.

7. Organise banking movements and cash flow

A bank account dedicated to the business helps separate personal and business transactions, monitor cash flow and reconcile financial movements.

This discipline should begin from day one. Even a simple business should be able to understand how much it receives, how much it pays and which financial commitments are expected over the following weeks and months.

8. Prepare accounting and invoicing processes

Accounting processes should be organised before the volume of documentation begins to increase. Invoices, expenses, bank transactions and contracts should all form part of a simple and consistent process.

Support from a Certified Accountant should not be viewed only as an administrative obligation. The information produced can help management understand costs, margins, results and financing requirements.

The company should also choose invoicing software that is appropriate for its activity, document volume and integration requirements. Invoicing, document archiving and information submission should operate as parts of the same process.

As the company begins to generate information, a management accounting approach allows the business to go beyond tax compliance and monitor costs, margins, cash flow and results in order to support decision-making.

Establishing a small set of financial indicators from the beginning can also help management track liquidity, profitability, debt and operational performance consistently.

9. Understand the main tax and Social Security obligations

Once incorporated, the company becomes subject to the obligations associated with its activity and structure. Corporate Income Tax, VAT, withholding taxes and Social Security contributions should be monitored according to the specific circumstances of the business.

For tax periods beginning in 2026, the standard Portuguese Corporate Income Tax rate is 19%. For certain SMEs and Small Mid Caps, a 15% rate applies to the first €50,000 of taxable income under the conditions established by law. The current wording can be consulted in Article 87 of the Portuguese Corporate Income Tax Code published by the Tax Authority.

Registration of companies with Social Security is mandatory and, in applicable cases, may occur automatically through the commercial registration process. Portuguese Social Security explains the company registration process in its respective guidance.

Where employees are hired, additional employment, Social Security, payroll and insurance responsibilities arise and should be prepared before the first employees are admitted.

How much does it cost to start a company?

The cost depends mainly on the incorporation channel selected and the complexity of the structure. Currently, the standard immediate incorporation process costs €360, while the digital option starts at €220 when a pre-approved contract template is used.

These amounts relate only to the formal procedure. The real investment should also take into account systems, professional advice, equipment, insurance, premises, recruitment, marketing and working capital. In most projects, the true cost of starting a company is therefore significantly higher than the administrative registration fee.

How long does the process take?

The timeframe depends on the method chosen and the complexity of the company. Procedures using standard documents and available company names tend to be faster than cases requiring additional documentation, a customised name or specific corporate rules.

Administrative speed should not replace proper preparation. Before incorporation, it should be clear who is participating in the business, how it will be financed, what activity it will carry out and how its financial and tax responsibilities will be organised.

Which documents and information should you prepare?

As a starting point, you should prepare:

• identification documents for the participants;
• applicable tax identification numbers;
• the intended company name;
• registered office and contact details;
• economic activity and CAE codes;
• identification of shareholders and management;
• distribution of quotas or shareholdings;
• intended share capital;
• articles of association or corporate agreement model;
• information required for the tax framework.

Where legal entities, representatives or less common structures are involved, additional documentation may be required. It is advisable to confirm the requirements of the selected incorporation channel in advance.

What should you do after the company has been created?

Once the company has been incorporated, the priority shifts to operations. Access credentials should be confirmed, administrative processes organised, tax compliance ensured, cash flow monitored and management systems prepared.

Where applicable, the company should also be registered with the relevant systems or confirm that automatic registrations and communications have been completed correctly.

The first 90 days of a company are particularly important because this is when the processes designed before launch begin to be tested by real operations.

Should financing and incentives be considered from the start?

Not every project requires external financing, but every project should estimate its capital requirements. Investment, innovation, recruitment or expansion may justify analysing different financing sources.

Portugal 2030 includes opportunities aimed at certain types of business investment. However, the existence of an open call does not mean that every project is eligible. An application should be based on a structured and financially sustainable investment.

For projects requiring additional investment, it is important to assess the different business financing and incentive options and determine which are best aligned with the company’s stage, objectives and financial capacity.

Companies planning Research and Development activities may also need to assess whether certain expenditure could qualify under SIFIDE, Portugal’s R&D tax incentive.

Common mistakes when starting a business

Choosing the structure based only on cost

The cheapest or fastest solution may not be the most appropriate for the level of risk, the participants involved or the expected growth of the business.

Underestimating cash flow requirements

A business may be viable and still face difficulties due to insufficient liquidity. Collection periods, fixed costs and initial investment should be projected before operations begin.

Mixing personal and business transactions

Financial separation makes control, documentation and analysis of the company’s true performance easier.

Leaving organisation until later

Delaying document management, control and reporting processes creates accumulated work. It is simpler to establish a basic routine from the first month.

Frequently asked questions

Is accounting support required?

Companies subject to formal organised accounting have specific obligations, and certain acts require professional intervention. The applicable framework should be confirmed according to the legal structure selected.

Can you start a company in Portugal without several shareholders?

Yes. There are legal structures suitable for a single founder. The choice should take into account liability, investment, activity and the expected development of the business.

Can the process be completed digitally?

Yes, where the applicable requirements are met. The digital system allows several steps to be completed without an in-person visit, although specific cases may still require additional documentation or review.

Is the legal minimum capital enough to start?

Not necessarily. The formal legal amount and the financial needs of the operation are two different things. The company should calculate the initial investment and liquidity required to support the first months of activity.

The next step

The incorporation process can be administratively quick, but building a solid foundation requires preparation. Company structure, activity, taxation, cash flow and financial information should be treated as parts of the same project.

After registration, the focus should shift to organising the first months of the company’s activity and creating processes that allow the business to be monitored using reliable information.
