Self-Employed Tax in Portugal

What is the recibos verdes system and who must use it?

Any person who regularly provides services or conducts business in Portugal without employing staff under a standard labour contract registers with the Autoridade Tributaria e Aduaneira (AT) as a trabalhador independente. Whenever payment is received, a recibo verde (green receipt) is issued through the Portal das Financas e-Fatura platform. Recibos verdes are the billing instrument for all Categoria B income and form the paper trail used by both AT and Seguranca Social. There is no minimum income threshold for registration: registration is required at the point of commencing the activity, not after hitting a revenue target. Clients with organised accounting are required to withhold IRS at source; the standard withholding rate on recibos verdes issued by professionals listed in Article 151 of the Codigo do IRS was reduced from 25% to 23% on 1 January 2025 by the Orcamento do Estado 2025 (Lei 45/2024), cited at source [1].

How does the simplified regime (regime simplificado) work?

The simplified regime under Article 31 of the Codigo do IRS (CIRS) applies automatically to trabalhadores independentes whose gross Categoria B income in the prior calendar year did not exceed 200,000 euros. Instead of deducting actual costs, the regime applies a fixed coefficient to gross receipts to produce the taxable base. The principal coefficients verified for the 2025 tax year are: 0.75 for professional services falling within the activity list in Article 151 CIRS (consultants, IT specialists, architects, engineers, lawyers, and most liberal professions); 0.35 for other service provision not on the Article 151 list; 0.15 for sales of goods and commercial activities; 0.95 for crypto-asset mining. The 0.75 coefficient means 75% of gross service income enters the progressive IRS calculation and 25% is treated as a deemed expense deduction. Workers whose actual documented costs exceed the deemed deduction fraction may benefit from electing organised accounting (regime de contabilidade organizada) instead, cited at source [2]. Where the coefficient is 0.75 or 0.35 and annual gross income exceeds 29,748 euros, the worker must demonstrate that at least 15% of gross receipts correspond to real, documented deductible expenditure; any shortfall is added back to taxable income.

New freelancers beginning self-employment for the first time qualify for a temporary reduction in the coefficient: 50% of the applicable coefficient in year one, 25% in year two. A worker qualifying for the 0.75 coefficient who earns 50,000 euros in their first year would therefore have a taxable base of approximately 18,750 euros (0.75 x 0.50 x 50,000) rather than 37,500 euros. The reduction does not apply if the worker had employment income, pension income, or closed a similar activity within the preceding five years, cited at source [2].

Organised accounting becomes mandatory once gross Categoria B income exceeds 200,000 euros in any calendar year. In that regime all actual costs directly linked to the activity may be deducted, a licensed Contabilista Certificado (chartered accountant under the Ordem dos Contabilistas Certificados) must be appointed, and full double-entry bookkeeping is maintained.

What are the IRS progressive rates applied to the taxable base?

Once the coefficient produces the taxable base, that amount is aggregated with other income sources and taxed at Portugal's nine-band progressive IRS scale set by Article 68 CIRS. The brackets in force for the 2025 tax year (income received January-December 2025, declared in the 2026 IRS campaign) are shown in the table below. A solidarity surcharge under Article 68-A CIRS adds 2.5% on the portion of total income between 80,000 euros and 250,000 euros, and 5% on the portion exceeding 250,000 euros, pushing the combined top marginal rate to 53%, cited at source [3].

The minimum existence threshold (minimo de existencia) for 2026 stands at 12,180 euros, meaning income up to that level is sheltered from IRS through a combination of the personal deduction and the structure of the lowest bracket, cited at source [4].

How do Social Security contributions apply to the self-employed?

Trabalhadores independentes are covered by the Codigo dos Regimes Contributivos do Sistema Previdencial de Seguranca Social (Lei 110/2009) and contribute at a flat rate of 21.4% on their relevant income base (rendimento relevante). For service-providers the relevant income base is 70% of total gross quarterly receipts; for sales activities it is 20% of gross quarterly receipts. A quarterly income declaration is filed through the Seguranca Social Direta online portal between the first and last day of the month following each quarter (April, July, October, January). Contributions are then paid monthly between the 10th and 20th of the subsequent month, cited at source [5].

New entrants benefit from a 12-month exemption from contribution payments starting from the date of registration as a trabalhador independente. Quarterly declarations are still submitted during the exemption period so that Social Security can compute the contribution base once payments resume. The IAS (Indexante dos Apoios Sociais), the reference index that anchors minimum contribution floors and benefit calculations, was set at 522.50 euros per month for 2025, cited at source [4].

What is the IFICI regime (NHR 2.0) for new residents?

The Incentivo Fiscal a Investigacao Cientifica e Inovacao (IFICI), introduced by Lei 82/2023 and effective from 1 January 2024, replaced the closed Non-Habitual Resident scheme as Portugal's inbound-talent tax incentive. Individuals who have not been Portuguese tax residents in the preceding five years and establish residency while taking up qualifying employment or self-employment may apply for a flat 20% IRS rate on Portuguese-source income from the eligible activity for up to 10 consecutive years. Qualifying categories include university researchers and lecturers (assessed by the Fundacao para a Ciencia e Tecnologia), directors and specialists in productive-investment projects certified by AICEP or IAPMEI, senior professionals in manufacturing, healthcare, IT, and scientific research, and board members of certified startups under Lei 21/2023. Applicants must hold at minimum a bachelor's degree (EQF Level 6) plus three years of relevant professional experience, or a doctoral qualification. Applications are submitted through the Portal das Financas after Portuguese tax residency is established, cited at source [6].

Foreign-source income earned by IFICI beneficiaries is generally exempt from Portuguese IRS while remaining reportable. Social Security obligations run under standard self-employed rules regardless of IFICI status. The regime is narrower than the grandfathered NHR scheme: general consulting or financial services income does not qualify unless it falls within a recognised category. Anyone who registered under NHR before 1 January 2024 (or established residency by that date and registered by 31 March 2024) continues under the prior NHR framework for the remainder of their 10-year window. A qualified tax professional familiar with Portuguese residency rules can assess which category a given activity falls under; see Portugal country overview for the broader residency context.

How does IVA (VAT) apply to recibos verdes?

Portuguese IVA under the Codigo do IVA applies to most professional services. The standard rate is 23% on the mainland, 22% in Madeira, and 16% in the Azores. Workers whose annual taxable turnover remains below 15,000 euros may claim exemption under Article 53 CIVA (regime especial de isencao), charging no IVA and recovering no input VAT. Workers who exceed the 15,000 euro threshold must register with AT within 15 days and begin charging IVA. Under rules effective 1 July 2025 a 25% buffer applies: workers who cross 15,000 euros but remain below 18,750 euros gain until 1 January of the following year to register; workers who cross 18,750 euros in a single invoice must apply IVA immediately from that invoice. Invoices issued to clients located outside Portugal do not count toward these thresholds. Periodic IVA declarations are filed quarterly for most independent workers; monthly filing applies to businesses with annual turnover above 650,000 euros, cited at source [7].

For most professional service-providers below the 15,000 euro threshold, IVA is a non-issue in the early years. Once turnover grows past the threshold, recibos verdes must display the IVA amount separately, and the worker registers for an IVA number through Portal das Financas. Engaging a qualified tax professional is strongly recommended when crossing the threshold mid-year to avoid misdated compliance and back-assessment.
