If you're freelancing in Portugal — or planning to — recibos verdes are how you invoice. Not optional, not informal. They're the official self-employment invoicing system, issued through the Portuguese Tax Authority (AT), and every independent worker providing services commercially needs to use them.
This guide covers the full picture: how to register, how the tax math works, social security, VAT, and the decisions that actually matter. No padding. Just what you need to know.
Recibos verdes (literally "green receipts") is the colloquial name for Portugal's self-employment invoice system. The name dates to when the forms were printed on green paper — the paper is gone, but the name stuck.
Today, all recibos verdes are issued digitally through the AT portal at e-fatura.irs.pt. Each receipt documents a service rendered by a self-employed individual (trabalhador independente), records the amount charged, and feeds directly into your tax record with Finanças.
If you're providing services as an individual — consulting, design, translation, coaching, writing, IT, legal, medical, or any professional activity — and you're not operating through a company, recibos verdes are your invoicing method.
Before you can issue a single receipt, you need to open activity (abertura de atividade) with the Tax Authority. This is done online through the AT Portal (Portal das Finanças) or in person at any Finanças office.
You'll select a CAE or CIRS code that describes your activity. Get this right — it affects which tax coefficients apply to your income and whether you're classified as a "regulated profession." When in doubt, a tax advisor can confirm the correct code before you file.
Once registered, you receive a confirmation and your status as a Category B taxpayer is active. You can now issue receipts.
Log into e-fatura.irs.pt with your NIF and AT password. Each time you complete a service, you generate a recibo verde directly in the portal. The system records: client NIF, description of services, value, IVA status, and date.
The receipt is automatically visible to AT. There's no manual submission required — the portal does that in real time.
Every receipt you issue is logged against your NIF. Your annual income from self-employment — the aggregate of all receipts issued during the calendar year — is what forms the basis for your IRS and social security calculations.
Self-employment income in Portugal falls under Category B of the IRS. Under the simplified regime (the default for most freelancers), you're not taxed on your full turnover. Instead, a coefficient (coeficiente de atividade) is applied to determine your taxable income.
For most services, the coefficient is 0.75 — meaning 75% of your revenue is treated as taxable income, and 25% is assumed to cover business expenses (no receipts required).
Some activities carry a lower coefficient of 0.35 — primarily intellectual or artistic work, under specific CIRS codes. If your activity qualifies, this is a significant tax advantage worth confirming.
From the resulting taxable income, you apply the standard progressive IRS rates (ranging from 13% to 48% depending on your bracket), plus any applicable surcharges.
Once your annual income exceeds a threshold, you'll be required to make quarterly provisional income tax payments — pagamentos por conta. These are advance payments toward your final IRS bill, calculated based on the previous year's liability. They're due in July, September, and December.
If you're new to Cat B income or your earnings are irregular, these can catch people off guard. Build the cash reserve early. Your annual tax filing reconciles the actual liability, and any overpayment is refunded.
Every year, you file your IRS return using Modelo 3. As a Category B taxpayer, you complete Anexo B, which captures your self-employment income, expenses claimed (if any), and any withholding tax (retenção na fonte) already paid by clients. The filing window is April–June of the following year.
Self-employed workers in Portugal pay social security at a rate of 21.4% — but not on 100% of their income. Contributions are calculated on 70% of declared income.
The practical effect: your effective social security rate is approximately 15% of gross revenue (21.4% × 70%).
Contributions are declared quarterly (in January, April, July, and October) based on the income from the prior quarter.
If this is your first time registering as self-employed in Portugal, you're exempt from social security contributions for the first 12 months. This is an automatic exemption — no application required.
After the exemption period ends, contributions kick in retroactively from the 13th month onward. Plan for this: the jump from zero to ~15% of revenue is real, and it surprises people who weren't tracking it.
The simplified regime (regime simplificado) applies automatically to self-employed workers with annual revenue under €200,000.
Under simplified accounting, you use the coeficientes described above. No need to track individual deductible expenses — the system assumes your costs are covered by the non-taxed portion of revenue.
Above €200,000, you're required to switch to organised accounting (contabilidade organizada), which works more like a company: you deduct actual documented expenses, maintain formal books through a certified accountant (TOC/ROC), and the income calculation is more granular.
For most freelancers, the simplified regime is adequate — and simpler. If you're approaching the threshold, the switch to organised accounting is worth planning for, not dreading. With proper expense tracking, it can actually reduce your tax burden.
If your annual turnover is below €14,500 (the 2024 threshold), you qualify for IVA exemption under Article 53 of the VAT Code. This means you don't charge VAT on your invoices and don't file periodic VAT returns. Simpler, but it also means you can't recover VAT on business purchases.
Once you exceed the Article 53 threshold — or if you opt out of the exemption — you must charge IVA on your invoices. The standard rate is 23% (Lisbon/Porto), with reduced rates of 13% and 6% for specific categories.
VAT is collected from your clients, declared on periodic returns (monthly or quarterly depending on volume), and remitted to AT. The net effect on your income is neutral — you're collecting on behalf of the state — but it adds administrative overhead.
If you're providing services to clients outside Portugal (EU or international), different rules apply. B2B services within the EU typically fall under the reverse charge mechanism. Get this right before invoicing foreign clients.
1. Not registering before invoicing. You cannot issue recibos verdes retroactively. If you start working without opening activity, you're already non-compliant. Register first.
2. Ignoring pagamentos por conta. These quarterly payments are often missed by freelancers who only think about tax in April. Miss them, and you face penalties on top of the final bill.
3. Misclassifying the activity code. The wrong CIRS code can mean the wrong coeficiente — and overpaying tax for years. It can also affect IVA exemption eligibility.
4. Forgetting the SS exemption ends. The 12-month social security exemption is finite. Many freelancers don't budget for contributions until they receive their first bill, which can be several quarters at once.
5. Assuming IVA exemption is permanent. The Article 53 threshold isn't a one-time election. If your revenue grows above €14,500, you lose the exemption and must register for IVA going forward.
6. Not withholding for clients. Certain client types (companies, ENIs) are required to withhold IRS at source (typically 25%) when paying you. If they don't, you may have an unexpected liability at year-end.
If you hold or are applying for IFICI status (the Incentivo Fiscal à Investigação Científica e Inovação — Portugal's preferential tax regime for qualifying professionals), your Category B income from eligible activities is taxed at a flat rate of 20% rather than the standard progressive scale.
This is a significant advantage for qualifying freelancers — particularly those in technology, scientific research, highly qualified professions, and certain investment roles. IFICI is fully compatible with the recibos verdes system. You still issue receipts and file Modelo 3 in the same way — the tax calculation on Anexo B simply reflects the preferential rate.
If you're considering IFICI and you're doing Category B work, the combination is one of the most tax-efficient setups available in Portugal. Full details at oncorporate.com/ifici.
Do I need an accountant to issue recibos verdes? No — you can manage the AT portal yourself. But for the tax return (Modelo 3), quarterly payment calculations, and decisions around IVA and accounting regime, professional support pays for itself quickly. Mistakes are harder to correct than they are to avoid.
Can I have recibos verdes alongside a regular employment contract? Yes. Portugal allows simultaneous Category A (employment) and Category B (self-employment) income. Both are declared on the same Modelo 3. Some coordination is needed to avoid double social security contributions — worth reviewing with a tax advisor.
What's the difference between recibos verdes and invoicing through a company? A company (LDA or SA) issues invoices separately from your personal NIF. Companies pay corporate tax (IRC at 21%) and then distribute dividends. For high earners, the company structure can be more tax-efficient — but comes with more compliance overhead. The crossover point depends on your income level and expense profile.
When does it make sense to switch from simplified to organised accounting? Before the mandatory €200,000 threshold, it can make sense if you have significant documented business expenses that exceed the non-taxed portion assumed under the simplified regime. Organised accounting lets you deduct actual costs.
Can I retroactively switch my CIRS activity code? Changes to your registered activity are possible, but retroactive corrections to issued receipts are limited. It's worth getting the code right from the start, especially if you qualify for a 0.35 coeficiente.
What happens if I miss the IRS filing deadline? Late filing of Modelo 3 results in penalties starting at €200 and increasing with the delay and outstanding amount. The AT can also apply interest on any unpaid tax. File on time — the April–June window is generous.
Whether you're registering your activity for the first time, navigating the transition to organised accounting, or combining recibos verdes with IFICI, the setup decisions you make early have compounding effects.
