Opening activity with finanças, invoicing, and the simplified regime
Swapping the grey skies of Britain for Portugal’s sun-drenched coast is a dream for many. The ongoing growth of remote work makes it possible for many professionals seeking more flexibility and a better quality of life to work remotely by 2025/26. If you’re considering freelancing in this lively country, understanding the latest changes to the local tax system is more important than ever. This article covers everything you need, including registering your activity with the tax authorities (finanças), understanding new invoicing rules, and staying compliant with the latest simplified tax regime.
Starting as a sole trader in Portugal, or Trabalhador Independente, involves registering your business activity (início de atividade) through the Finanças portal or at a tax office. For 2025/26, this still requires you to declare the type of work you do using your profession’s current CAE code and to provide your personal details. This process must be completed before issuing your first invoice and officially recognises you as self-employed by the Portuguese authorities.
Starting your self-employment journey
Initially, select your preferred accounting regime during registration. Most new freelancers will benefit from the regime simplificado (simplified regime), which remains as the default. Under recent rules, this regime considers a fixed percentage of your revenue as expenses, eliminating the need to itemise every cost. For most service-based roles, 75% of your income remains taxable, but always verify for your CAE-specific updates.
You also decide on Value Added Tax (VAT), or IVA. For the 2025/26 tax year, the annual turnover threshold for VAT exemption under Article 53 remains at €15,000. If your expected turnover is less than this, you can apply for exemption, which simplifies your compliance and removes the obligation to charge or file IVA on your invoices. If your annual revenue is likely to exceed €15,000, mandatory IVA registration and quarterly filings apply from the beginning.
Understanding invoicing and VAT obligations
Once registered, Portuguese law mandates that all freelancers issue invoices (faturas-recibo) for any income, using certified invoicing software authorised by Finanças. Many modern, cloud-based systems tailored for 2025’s requirements are available in both English and Portuguese. These tools ensure your invoices are securely registered and directly reported to the tax office.
Each invoice must include current details: your name, NIF (tax identification number), the client’s information, a unique invoice ID, the date, a clear description of the service, and the total amount. For those registered for VAT in 2025/26, the new standard rate (currently 23% nationally) and the calculated tax amount must be clearly specified. If you are exempt under Article 53, include ‘IVA – regime de isenção, Artigo 53º CIVA’ as instructed by the 2025 guidelines.
Social Security and income tax updates
Freelancers must register with Segurança Social (Social Security) and contribute. For the 2025/26 period, new freelancers can still benefit from a 12-month exemption from contributions upon initial registration. After this, monthly payments are required. The standard contribution rate in 2025/26 remains at 21.4% of your relevant income base, but it’s important to plan ahead for these ongoing payments as the Social Security system is actively reviewing contribution enforcement.
Personal income tax (IRS, Imposto sobre o Rendimento das Pessoas Singulares) is submitted annually, including any global earnings. Under the simplified regime, taxable income is determined by applying the relevant coefficient (usually 75% for most services) to gross revenue. For 2025/26, progressive rates remain from 13.25% up to 48%, with minor threshold adjustments. If you are a Non-Habitual Resident (NHR), advantageous tax treatment might still be available, although updated eligibility rules now apply from January 2025.
Best practices and final thoughts
To ensure a smooth journey, meticulous record-keeping is essential. While the simplified regime reduces paperwork, you must still retain digital or physical proof of all invoices, receipts, and relevant correspondence. Proactive budgeting for both IRS and Social Security payments will support financial stability throughout the year. Although the Portuguese tax system may seem daunting at first, the revised rules for 2025/26 offer greater clarity and are designed to promote entrepreneurial growth.
Starting a freelance career in Portugal offers significant opportunities. With proper guidance, you can stay compliant, maximise your earnings, and enjoy all that the country provides as you develop a successful business.
