CAE vs CIRS Portugal: What Activity Code Do You Actually Need as a Designer?

The search query "CAE 1336 Portugal" or "activity code designer freelance" typically returns generic guides that don't address the core problem: the number 1336 refers to a CIRS Art. 151 code, not a CAE code, and the two systems have nothing in common beyond the domain they cover.

That distinction matters practically. The code you register under governs your IRS coefficient, your withholding rate, and your entire simplified-regime tax calculation. Getting it wrong doesn't just cause an administrative headache; it can mean you're overpaying tax every year without realizing it.

Two systems with one shared purpose but nothing else in common

CAE (Classificacao Portuguesa de Atividades Economicas) is Portugal's implementation of the EU NACE classification. It's maintained by INE (Instituto Nacional de Estatistica), the national statistics office. It classifies economic entities: companies, associations, branches, and establishments. When a Lda forms, it picks a CAE. CAE 74120 ("Actividades de design") is the code for a design studio operating as a company.

CIRS Art. 151 is a list maintained by AT (Autoridade Tributaria e Aduaneira), the tax authority. It classifies individual independent professionals, the people Portugal calls trabalhadores independentes who issue Recibos Verdes. When you open your activity at the Portal das Financas as a sole-proprietor freelancer, you choose a code from this list.

Same domain, different universe. CAE 74120 for a design company. CIRS 1336 for a freelance designer. Neither number is interchangeable with the other system.

The CAE glossary entry covers both systems side by side, and the CIRS glossary entry explains the broader context of how the Art. 151 table fits into Portuguese tax law.

What CIRS 1336 actually covers

Code 1336 in the Art. 151 table is "Designers." This is a broad category that covers the visual, industrial, and communication design professions as a whole: graphic designers, UX and UI designers, product designers, industrial designers, fashion designers, interior designers working independently.

The criterion is design work as a professional activity. If you are creating visual systems, user interfaces, product forms, or communication materials as a freelance professional, 1336 is your code.

Three adjacent codes come up regularly in the same searches as 1336:

CIRS 1332 ("Programadores informaticos"): software developers and engineers who write and implement code. If you design interfaces and someone else implements them, you're on 1336. If you implement as well as design, the primary activity governs, and many developer-designer hybrids end up on 1332. See the CIRS 1332 guide for the full breakdown.

CIRS 1313 ("Analistas de sistemas"): systems analysts who design technical architectures and information systems. Occasionally relevant to UX professionals whose work involves system design, but most UX designers land on 1336.

CIRS 1320 ("Consultores"): consultants. Used by designers who have pivoted toward consulting, strategy, or advisory work and whose primary deliverable is advice rather than designed artifacts. See the CIRS 1320 guide.

All three carry the 0.75 coefficient. The distinction is about what you primarily produce.

There is also CIRS 1519 ("Outros prestadores de servicos"), the catch-all for professions not specifically named in the Art. 151 table. Its coefficient is 0.35, not 0.75, and that gap is worth being honest about: 1519 makes only 35% of your gross taxable where 1336 makes 75% taxable, so on paper it looks like the cheaper code. It is not a choice. Designers are specifically named in the Art. 151 table, so 1336 is the code that applies, and AT classifies income on the activity you actually perform rather than the code you filed. A designer sitting on 1519 is not saving tax, they are carrying an unrecognised liability: the exposure is a reassessment at the correct coefficient plus penalties and compensatory interest, for every year the misclassification ran.

The tax mechanics for CIRS 1336 designers

The 0.75 coefficient. Under the simplified regime, 75% of your gross revenue is taxable. The remaining 25% is treated as assumed business costs: you don't need receipts for it, and you can't substitute actual expenses in its place even if your real costs were higher. Social Security contributions are separately deductible on top.

First-year discount. In your first calendar year of activity, only 37.5% of gross revenue is taxable, half the standard rate. In year two, 56.25%. This is based on the calendar year, not 12 months from your start date. Open your activity in March rather than October and you get nine months at the reduced rate instead of two.

To qualify: no employment or pension income in the same year, and no similar activity closed in the last five years.

Documented expense requirement. You still need to prove 15% of gross income in documented expenses: invoices with your NIF registered in the e-fatura system. An automatic specific deduction of roughly €4,587.09 (2026) counts toward this, or your Social Security contributions up to a cap of 10% of your gross, whichever is larger. See the 15% expense rule fact page for the full mechanics.

Withholding from Portuguese clients. When a Portuguese entity pays you for professional services, they're required to withhold 23% at source and send it directly to AT. Since 1 January 2025, that's the default rate (reduced from 25% by OE2025, Lei 45-A/2024, Art. 101 CIRS).

Withholding from foreign clients: nothing. This is the point that catches expat designers most off guard.

When your Berlin agency or Amsterdam client pays you €6,000 for a brand identity, all €6,000 lands in your account. No tax has been sent to AT. The IRS liability on that income is real; the mechanism that pre-pays it for Portuguese clients simply doesn't exist for foreign ones. Budget separately.

The expat designer layer

Most guides covering CIRS 1336 are written for Portuguese designers working primarily with Portuguese clients. If you moved from Sweden, the Netherlands, Germany, or the UK and your client base is back home or spread across Europe, several of those guides quietly stop applying to you.

Your old invoicing software is not legal here

Every platform used to issue legally valid Portuguese invoices must be certified by AT under Portaria 363/2010. Certified software assigns ATCUD codes to every document, communicates with AT systems, and generates the SAF-T audit file.

Canva's invoice feature, Adobe Acrobat's PDF invoices, FreshBooks, and similar tools are not AT-certified and cannot serve as your primary Portuguese invoicing system. This applies to CIRS 1336 designers the same as everyone else. If you arrived with an existing invoicing setup from abroad, those invoices are not valid in the Portuguese tax system.

The free fallback is the AT portal itself (Portal das Financas, "Faturas e Recibos Verdes"), certified and free. For more on the certification landscape and what to look for, see the expat freelancer tax automation guide.

Invoicing EU clients: 0% VAT, but not zero obligations

When you invoice a business client in another EU country, you issue at 0% VAT under Art. 6 CIVA. The place of supply is the customer's country; they reverse-charge in Germany, the Netherlands, or wherever they are. You use exemption code 115.

But 0% VAT is not the same as no VAT obligations. You must file the Declaracao Recapitulativa, a quarterly EU reporting document tracking intra-community B2B service transactions. It is required from your first EU invoice, regardless of whether you are on the Art. 53 VAT exemption (the €15,000.00 threshold for domestic outbound invoicing).

Art. 53 covers what you send to Portuguese clients. It does not exempt you from cross-border reporting. See the Art. 53 exemption glossary entry for the full scope.

Foreign SaaS subscriptions: reverse-charge from day one

Figma, Adobe Creative Cloud, Notion, Midjourney. These are EU or US-based businesses providing services to a Portuguese-resident business customer (you). Under Art. 2(1)(g) CIVA, you're the sujeito passivo for those acquisitions. You self-assess and file reverse-charge VAT on them through your Declaracao Periodica.

This obligation exists from the first foreign supplier invoice. Art. 53 status does not exempt you from it.

Practical consequence: if you have only Portuguese clients and no foreign software subscriptions, you likely have no Declaracao Periodica to file under Art. 53. The moment you subscribe to Figma or Adobe, you have one.

---

The compliance picture for a CIRS 1336 designer with foreign clients: AT-certified invoicing, 0% VAT on EU B2B invoices with Declaracao Recapitulativa filed quarterly, Declaracao Periodica for reverse-charge VAT on foreign SaaS tools, no withholding from foreign payments so you're managing your own tax provision, quarterly Social Security declarations. None of it is complicated once you know it exists.

If you're starting out and want invoicing that's compliant from the first document, Descodify is AT-certified, handles the ATCUD and SAF-T requirements, and produces the Declaracao Recapitulativa for EU clients. The free tier covers invoicing; Completo (€19/month) covers VAT, Social Security, and IRS preparation.
