Accounting for Freelancers (Trabalhadores Independentes) in Portugal

Freelancing in Portugal means operating as a trabalhador independente — a self-employed individual who issues recibos verdes (green receipts) for services rendered. This legal status is accessible, flexible, and increasingly popular among consultants, designers, developers, translators, and other knowledge-economy professionals. However, it comes with a distinct set of tax, Social Security, and invoicing obligations that require careful management to remain compliant and financially efficient.

HVR Business Consulting provides dedicated accounting support for freelancers at every stage — from registering your activity with the AT and Segurança Social, through to annual IRS filings and strategic advice on when incorporating a company makes financial sense.

What Are Green Receipts (Recibos Verdes)?

Recibos verdes are the official electronic receipts that freelancers issue through the AT's portal (Portal das Finanças) each time they complete a service. They record the nature of the service, the gross amount, any applicable withholding tax (retenção na fonte), and the client's tax identification number (NIF). Since 2020, all recibos verdes must be issued digitally and must include an ATCUD code. HVR can set you up with AT-certified billing software to issue compliant receipts in seconds.

Simplified Regime vs Organised Accounting

Most freelancers start under the simplified regime (regime simplificado), which is available to those with annual gross income below €200,000. Under this regime, taxable income is calculated by applying fixed statutory coefficients to gross revenue — no need to itemise expenses:

• 0.75 coefficient for the professions in the article 151 table: 75% of that income is taxable; the remaining 25% is assumed to cover costs.
• 0.35 coefficient for other services: 35% of that income is taxable.
• 0.15 coefficient for sales of goods and products: Only 15% of that revenue is taxable (article 31(1) of the IRS Code).

The simplified regime is administratively light but inflexible. When your actual deductible expenses (rent, equipment, subscriptions, professional training) exceed the 25% assumed by the 0.75 coefficient, switching to organised accounting (contabilidade organizada) — which taxes real net profit — often produces a lower IRS bill despite the added accountancy cost.

Social Security Contributions

Freelancers contribute to Social Security in two steps. First, relevant income: 70% of gross service fees, or 20% of income from producing and selling goods and from hotel, restaurant and beverage services (Article 162(1) to (3) of the Contributory Code, as amended by Decree-Law 2/2018). Second, the monthly contribution base equals one third of the relevant income of the quarter (Article 163(1)), with effect in that month and the two that follow. The 21.4% rate (Article 168(1)) applies to that base — an effective 14.98% of service income. The base is capped at EUR 6,445.56/month, 12 x IAS (Article 163(5)), and the minimum contribution is EUR 20/month (Article 163(2)). The figures are refreshed each quarter from the previous three months. Registration in the regime only produces effects on the first day of the 12th month after activity begins (Article 145(1)) — a key cash-flow benefit for those just starting out.

IVA (VAT): Exemption Threshold and Quarterly Declarations

Freelancers with annual turnover below €15,000 qualify for the Article 53 CIVA VAT exemption — they do not charge VAT to clients and do not file VAT returns, which significantly simplifies administration. This threshold is reviewed annually; once exceeded, you must register for VAT, apply the standard 23% rate (or relevant reduced rate), and submit quarterly VAT declarations. For high-volume freelancers exceeding €650,000 annual turnover, declarations become monthly.

Withholding Tax (Retenção na Fonte)

When a freelancer provides services to a Portuguese company or public entity, the client is legally required to withhold 23% of the gross fee for the professions in the article 151 table, or 11.5% for other services (article 101(1)(b) and (c) of the IRS Code) and remit it directly to the AT. This withheld amount is a prepayment of your annual IRS liability and is fully credited against the final tax due. Retentions are tracked by HVR throughout the year to model your likely IRS outcome before the April filing deadline.

Annual IRS Return

The annual IRS return for freelancers is filed in April for the prior calendar year using the AT's Portal das Finanças. Under the simplified regime, the pre-filled return applies the statutory coefficients automatically. Under organised accounting, your accountant certifies and submits the full income statement. Either way, HVR reviews your return before submission to catch errors, claim all eligible deductions, and ensure withholding credits are correctly applied.

When to Switch from Freelancer to Company

Incorporating a Unipessoal Lda. or Lda. becomes financially advantageous when annual net profit consistently exceeds approximately €30,000–€40,000, because corporate income tax (IRC) at 15% (SME reduced rate on the first €50,000 taxable profit, Law 64/2025) is lower than the top IRS bands applied to freelance income. Other triggers include needing to reinvest profits in the business, hiring employees, separating personal and business liability, or winning clients who prefer a formal company entity.

Frequently Asked Questions

Q: Can I deduct home-office expenses as a freelancer?
Under the simplified regime, expenses are not deducted one by one: tax is charged on a fixed share of income (75% for the professions in the article 151 table, 35% for other services, article 31(1) of the Personal Income Tax Code). Under organised accounting, a proportional share of rent, utilities and internet can be deducted, provided the space is genuinely used for the activity and documented.

Q: Do I need an accountant if I am below the VAT threshold?
There is no legal obligation to retain an accountant as a freelancer (unlike companies, which must have an OCC). However, even below the VAT threshold, professional accountancy support ensures your annual IRS return is optimised, your Social Security base is correctly calculated, and you are advised in advance of threshold crossings.

Q: What happens if I exceed €200,000 in turnover?
You leave the simplified regime if the €200,000 limit is exceeded in two consecutive years, or in a single year by more than 25%. Organised accounting then applies from the following year (article 28 of the Personal Income Tax Code) and requires a certified accountant (OCC). HVR can manage this transition, including setting up full bookkeeping from your opening balances.
