The two primary options are mainland Portugal and the islands. Each location offers distinct advantages and challenges, particularly in terms of tax benefits, legal requirements, operational costs, and long-term sustainability.

Why choose Portugal for your business?

The Portuguese market offers diverse business opportunities across industries such as tourism, technology, manufacturing, and logistics.

Tax benefits of mainland Portugal
Corporate income tax rates
Mainland Portugal applies a standard corporate income tax rate of 20% on taxable profits. Small and medium-sized enterprises (SMEs) benefit from a reduced rate of 16% on the first €50,000 of profit and 20% thereafter. Additionally, some regions offer further tax incentives to encourage investment in innovation, renewable energy, and the tourism industry.
Regional tax incentives
Certain mainland regions provide additional tax benefits to stimulate economic development. These incentives may include tax credits, grants, and subsidies for companies investing in research & development, sustainable projects, or job creation.
Business environment and market access
Mainland Portugal offers access to a large domestic market and the wider European Union, facilitating free movement of goods, services, and capital. Major cities such as Lisbon, Porto, and Braga have vibrant business districts, excellent infrastructure, and skilled professionals, making them attractive for startups and established companies alike.
Tax benefits of Madeira
Madeira International Business Centre (IBC)
Madeira’s IBC offers one of the lowest corporate tax rates in Europe at 5%, applicable until 31 December 2028 – although it keeps being extended – for companies meeting specific eligibility criteria. This reduced rate is designed to attract foreign entrepreneurs and companies engaged in international trade, shipping, and services.
VAT and withholding tax exemptions
Companies registered under the IBC benefit from VAT exemptions on international transactions and no withholding tax on dividends paid to EU-based shareholders. These advantages make Madeira an appealing location for businesses with global operations.
Eligibility and compliance requirements
To qualify for IBC benefits, companies must meet conditions such as creating local jobs, maintaining economic substance on the island, and investing in regional infrastructure. These requirements impose a higher compliance burden compared to mainland Portugal.
Maintaining the company setup: Mainland
Tax filing and financial reporting
In mainland Portugal, companies must adhere to regular tax filing and financial reporting obligations to maintain good standing. This includes submitting annual corporate income tax returns and audited financial statements to the Portuguese tax office and commercial register. Small and medium-sized companies benefit from reduced corporate tax rates on the first tranche of taxable profits but must comply with all filing deadlines and documentation standards. Accurate bookkeeping and transparent accounting practices are essential to ensure compliance and avoid penalties or audits.
Social Security and employment compliance
Maintaining a company in mainland Portugal also requires compliance with social security and employment laws. Employers must register employees with the social security system and make regular contributions based on gross salaries. These contributions fund benefits such as healthcare, retirement pensions, and unemployment support. Companies must also adhere to labor regulations, including minimum wage requirements, working hours, and workplace safety standards. Ensuring compliance in these areas protects the company from legal disputes and supports a stable workforce.
Licences, permits, and business operations
Companies operating on the mainland must keep all necessary licenses and permits up to date, depending on their business sector. This includes permits for retail businesses, construction, food service, and other regulated industries. Maintaining a valid business bank account and managing financial operations transparently are also critical for ongoing compliance. Companies should stay informed about changes in relevant laws and tax regulations to ensure continued legal compliance.

The importance of having a certified accountant in Portugal
One of the most critical aspects of operating a business in Portugal is the mandatory requirement to have a certified accountant (Contabilista Certificado). This is not just a recommendation—it’s a legal obligation.
Why is a certified accountant essential?
A certified accountant ensures your company meets all tax and financial reporting obligations. They handle:
- Tax filings: submit corporate income tax, VAT, and employee-related taxes.
- Financial statements: prepare and file annual accounts in compliance with Portuguese accounting standards.
- Payroll management: ensure proper calculation and payment of social security contributions and wages.
- Regulatory compliance: keep your business aligned with the latest laws and regulations to avoid penalties.
Benefits of working with a certified accountant
Hiring a certified accountant not only ensures legal compliance but also brings peace of mind, knowing your finances are in expert hands. Partnering with an accounting firm experienced in Portuguese regulations, like RHJ Accountants, can make all the difference in running a successful business.

Maintaining the company setup: Madeira
Compliance and economic substance requirements
To maintain the favourable 5% corporate tax rate under Madeira’s International Business Centre (IBC) regime, companies must fulfil strict economic substance and compliance criteria. This includes demonstrating genuine business activity on the island, such as having a physical office space and employing a minimum number of local staff. The exact employment thresholds vary depending on the industry sector but generally require a significant local workforce to ensure the company is contributing to Madeira’s economy. Additionally, companies must ensure their management and decision-making processes take place within Madeira to comply with substance requirements. These measures are designed to prevent companies from merely using Madeira as a tax haven without real economic presence.
Reporting and regulatory obligations
Companies benefiting from the Madeira IBC regime must submit annual financial statements and tax returns to the Portuguese tax authorities within prescribed deadlines. Compliance with relevant Portuguese laws and regulations is mandatory, including adherence to accounting standards and timely payment of corporate taxes. The company must also maintain proper bookkeeping and accounting records that accurately reflect its business activities. Failure to comply with reporting obligations or meet economic substance requirements can lead to the revocation of the 5% tax rate, resulting in the application of standard corporate tax rates. Regular audits and inspections by authorities may also be conducted to verify compliance.
Maintaining eligibility and operational continuity
Beyond tax compliance, companies must ensure ongoing operational activities in Madeira to retain eligibility for the IBC benefits. This includes renewing any required licenses or permits, maintaining active business operations, and meeting any sector-specific criteria imposed by the Portuguese government or regional authorities. Companies should also monitor changes in legislation or regulatory frameworks that may affect their status under the IBC scheme. Engaging local legal and accounting experts is highly recommended to navigate these requirements effectively and sustain the tax advantages offered by Madeira’s regime.
Conclusion: choosing the right location in Portugal
Deciding between mainland Portugal and the island regions depends on your business model, target market, and tax priorities. Mainland Portugal offers access to a large market, robust infrastructure, and moderate tax rates, making it ideal for businesses focused on local and EU markets. Madeira and the Azores provide attractive tax incentives and lower operational costs but come with additional compliance requirements and niche market focuses.
