If you’ve moved to Portugal to freelance — or you’re already here and just landed your first client — you’ll quickly bump into the phrase recibos verdes (“green receipts”). It’s not a separate tax regime so much as the everyday name for how self-employed people invoice and pay tax in Portugal. There’s no paperwork mountain, but there is a sequence you need to get right, because mistakes here tend to surface months later as a Segurança Social debt notice or an IRS correction.
This guide walks through registration, invoicing, withholding, VAT, and social security as they actually work for freelancers in 2026 — not the simplified version you’ll see on forums.
Step 1: Register início de atividade before you invoice anything
You cannot legally issue a recibo verde until you’ve opened activity (início de atividade) with the Autoridade Tributária. This is done online through the Portal das Finanças, and it needs a NIF and, in most cases, a Portuguese address or fiscal representative already in place.
When registering, you’ll choose:
- Your CAE code (activity classification) — this drives which withholding coefficient applies later.
- Your VAT (IVA) regime — exemption or standard.
- Your accounting regime — almost everyone starts on regime simplificado.
The registration itself is free and usually processed same-day, and once it’s done you can start invoicing immediately through the e-Fatura portal.
Step 2: Understand regime simplificado (the default for almost everyone)
The regime simplificado applies automatically if your turnover is under €200,000/year, and it’s what nearly all freelancers use.
Instead of tracking every expense, the tax authority applies a fixed coefficient to your invoiced income to estimate taxable profit — for most services, roughly 75% of your income is treated as taxable, with the remaining 25% assumed as costs. If your real expenses are much higher than that (renting a studio, buying equipment, travel), organised accounting — where you deduct actual costs — can work out cheaper, but it comes with more bookkeeping and usually a certified accountant.
Step 3: Withholding tax on your invoices
When you invoice a Portuguese company (not usually private individuals or foreign clients), that company is often required to withhold IRS at source and pay it directly to the tax authority on your behalf — an advance against your annual tax bill, not a final tax. Freelancers issuing recibos verdes keep the lowest withholding rate, at 23%, and unlike employees this rate is fixed regardless of income level. That’s down from 25% in recent years, so if you’re quoting old advice, adjust it.
You’re exempt from withholding if your expected annual income falls below a set threshold and you notify your client in writing before invoicing — this applies if you’re in the simplified regime and bill less than €15,000 a year. Declare it wrongly and you risk owing a lump sum at tax-return time, so only opt out if you’re confident about your annual total.
Clients based outside Portugal generally don’t withhold Portuguese tax at all — that’s a common point of confusion for remote freelancers working mostly with foreign companies.
Step 4: VAT (IVA) — when you need to start charging it
Under Article 53 of the VAT code, freelancers below a turnover threshold don’t charge IVA at all. If you bill less than €15,000 a year, you’re exempt. Cross that line and you must start charging IVA (usually 23% on the mainland) going forward — and you generally have a short window to notify Finanças once you realise you’ll exceed it.
Being IVA-exempt is simpler for invoicing but means you can’t reclaim VAT on business purchases. Many freelancers with EU/international B2B clients opt into the standard regime early because of reverse-charge rules on services sold abroad — worth a conversation with an accountant if most of your clients are outside Portugal.
Step 5: Social security contributions
This is the part freelancers most often forget to budget for, because — unlike withholding — Segurança Social contributions are not deducted automatically from your invoices.
The general contribution rate for self-employed workers is 21.4% on the contribution base, calculated on the relevant income — 70% of your Category B services income. You declare income quarterly (in January, April, July, October) and pay monthly based on that declaration. The minimum contribution when income is low or absent is €20/month, and the maximum monthly base is capped at 12 times the IAS.
The good news for anyone just starting out: when you open activity for the first time as a self-employed worker, you automatically get a 12-month exemption from social security contributions — provided you haven’t had self-employed activity in the previous 3 years. Contributions kick in automatically from month 13, so mark your calendar.
Withholding, VAT and social security at a glance
| Obligation | Rate/threshold (2026) | Who it applies to |
|---|---|---|
| IRS withholding | 23% of invoiced amount | Invoices to Portuguese companies above the exemption threshold |
| Withholding exemption | Turnover under ~€15,000/year, declared in writing | Simplified-regime freelancers |
| VAT (IVA) | Exempt under €15,000/year; 23% above | All self-employed on Article 53 |
| Social security | 21.4% on 70% of relevant income | All self-employed, after month 12 |
| First-year exemption | 12 months, automatic | New activity, no self-employment in prior 3 years |
Figures change with the state budget — always confirm current thresholds on the Portal das Finanças and Segurança Social before invoicing.
Common mistakes freelancers make
- Not setting money aside. Between withholding, IVA (if applicable) and social security, a meaningful chunk of each invoice isn’t really yours yet. A rough rule many freelancers use: assume roughly a fifth to a quarter of gross invoiced income will go to tax and contributions combined, and adjust once you see your real numbers.
- Declaring “zero” and forgetting the quarterly Segurança Social filing. It’s still mandatory even with no income that quarter — skipping it can trigger minimum contributions or penalties.
- Wrongly claiming the withholding exemption, then blowing past the threshold — this creates a surprise bill at annual filing.
- Ignoring organised accounting when expenses are high. If you’re renting an office or investing heavily in equipment, the simplified regime’s flat coefficient may be costing you more than it should.
If you’re also weighing NIF setup, tax residency, or whether IFICI (the successor to NHR) applies to your situation, it’s worth reading our broader guides on tax and the NIF and company setup before deciding between freelancing solo and incorporating an Lda. Freelancers coming from abroad should also check our relocation and visas guides for how income requirements interact with residence permits, and our banking guide if you still need a Portuguese account to receive payments.

FAQ
Do I need a Portuguese company to freelance legally in Portugal?
No. Most freelancers operate as sole traders (trabalhador independente) under their personal NIF, without forming a company. An Lda only becomes worth considering at higher income levels or for liability reasons — see our company setup guide for that comparison.
Can I invoice foreign clients through recibos verdes?
Yes — plenty of remote freelancers in Portugal bill clients abroad this way. Portuguese withholding tax generally doesn’t apply to foreign-client invoices, though your income is still declared and taxed in Portugal if you’re tax resident here.
What happens if I miss a quarterly social security declaration?
Segurança Social can apply the minimum contribution automatically and, in some cases, penalties for late filing. It’s a required declaration even in quarters with zero income, so don’t skip it just because you didn’t invoice.
Is the 25% expense assumption in regime simplificado always accurate?
No — it’s a flat coefficient, not a reflection of your actual costs. If your real business expenses are consistently higher than 25% of income, organised accounting (with a certified accountant) usually saves more tax, though it adds bookkeeping overhead.
Does freelancing income count toward D7 or D8 visa requirements?
It can, but AIMA assesses each case on the evidence provided — stable, documented income matters more than the specific structure. Outcomes depend on the caseworker and file, so treat any income threshold as a guide, not a guarantee, and check current requirements on AIMA or our visas guide.
