How to Register for VAT (IVA) in Portugal (2026): Step-by-Step Guide

TL;DR: To register for VAT (IVA) in Portugal, you submit Form 1862 (or an equivalent declaration of commencement) to the Autoridade Tributária e Aduaneira (AT). Businesses with annual turnover below €15,000 may claim a small-business exemption under Article 53 of the VAT Code. Registration is mandatory before you exceed that threshold.

What Is the VAT Registration Threshold in Portugal?

Portugal's VAT exemption threshold is €15,000 in annual turnover, unchanged for 2026. If your taxable supplies remain below this figure, you may operate under the Article 53 exemption and avoid charging IVA. Once you breach €15,000 — or expect to — you must register and begin applying the standard 23% IVA rate.

Portugal applies three IVA rates under the VAT Code (Código do IVA):

• Standard rate: 23% (mainland Portugal)
• Intermediate rate: 13% (food products, wine, catering, hotels)
• Reduced rate: 6% (basic foodstuffs, pharmaceuticals, books, passenger transport)

Note: Azores and Madeira apply lower regional rates (18%/9%/4% and 22%/12%/5% respectively) because they are autonomous regions with separate fiscal competences.

The Autoridade Tributária e Aduaneira (AT) administers IVA. All registrations, returns, and SAF-T submissions pass through the AT's Portal das Finanças (portaldasfinancas.gov.pt).

Who Must Register for IVA in Portugal?

You must register for IVA if you meet any one of these conditions — there is no grace period once the trigger is met.

You are obligated to register if:

• Your annual taxable turnover exceeds €15,000 (Article 53 threshold).
• You are a non-resident business making taxable supplies in Portugal.
• You acquire goods from other EU member states exceeding the intra-Community acquisition threshold.
• You receive services from foreign suppliers subject to the reverse-charge mechanism.
• You voluntarily choose to waive the Article 53 exemption — permitted even below the threshold.

Certain activities — including those carried out by public bodies and specific exempt supplies under Article 9 of the Código do IVA (health, education, social welfare, financial services, insurance) — are outside the scope of IVA entirely and do not trigger a registration obligation.

Non-established businesses (companies incorporated outside Portugal supplying taxable goods or services within Portugal) must register immediately, with no threshold protection.

Step-by-Step: How to Register for VAT in Portugal

Registering for IVA in Portugal follows a clear administrative process through the AT. Most business owners complete it in under two hours once documents are assembled. Here is the exact sequence.

Step 1 — Obtain a NIF (Número de Identificação Fiscal)

Before you can register for IVA, you need a Portuguese tax identification number. Portuguese citizens already hold an NIF. Foreign nationals or foreign companies must apply at a Finanças office or appoint a fiscal representative to obtain one. A fiscal representative is legally required for non-EU businesses.

Step 2 — Prepare Your Documents

Gather the following before beginning the online declaration:

• NIF of the business (and of all partners/directors for partnerships and companies)
• Business activity description (CAE code — Classificação das Atividades Económicas)
• Estimated annual turnover
• Start date of activity
• Bank account details (IBAN) for any refund claims
• Passport or identification document (for non-residents)

Step 3 — Submit the Declaration of Commencement (Declaração de Início de Atividade)

Log in to the Portal das Finanças at portaldasfinancas.gov.pt using your NIF and AT password. Navigate to Entregar → Declarações → IVA → Declaração de Início de Atividade. Complete the electronic form (equivalent to the paper Form 1862), selecting your IVA regime:

• Regime de Isenção (Article 53): if you expect turnover below €15,000 and do not wish to charge IVA
• Regime Normal: standard IVA taxpayer, filing monthly or quarterly returns

You may also submit the declaration in person at any local Finanças service counter.

Step 4 — Receive Your IVA Number

Portugal does not issue a separate VAT number. Your NIF is also your IVA number. For EU cross-border transactions (EC Sales Lists, intra-Community supplies), your IVA number is formatted with the country prefix: PT + NIF (e.g., PT123456789).

The AT activates your IVA status typically within a few business days of accepting your declaration.

Step 5 — Set Up Certified Invoicing Software

Portugal law requires all IVA-registered businesses to use certified invoicing software approved by the AT. Software must generate invoices with a unique sequential code, a QR code, and an ATCUD (código único de documento). Non-compliance triggers penalties.

Software must also produce SAF-T (PT) files — a standardised XML export of all accounting and invoicing data — which the AT can request at any time and which underpins the annual SAF-T submission.

Step 6 — Understand Your Filing Frequency

Once registered under the Regime Normal, your IVA return frequency depends on your previous year's turnover:

• Monthly returns: businesses with annual turnover above €650,000 in the preceding year
• Quarterly returns: businesses with annual turnover at or below €650,000

Returns are filed electronically via the Portal das Finanças. Monthly returns are due by the 10th of the second month following the tax period. Quarterly returns are due by the 15th of the second month following the quarter.

IVA Rates Compared: Portugal vs. EU Peers

The table below uses only verified data from EU member states with confirmed figures.

Country	Standard VAT Rate	Reduced Rate(s)	Small-Business Threshold
Portugal	23%	13% / 6%	€15,000
Germany	19%	7%	€25,000 (prior year) / €100,000 (current year)
France	20%	10% / 5.5% / 2.1%	€85,000 (goods) / €37,500 (services)
Netherlands	21%	9%	€20,000 (KOR scheme)
Spain	21%	10% / 4%	No threshold — register before first taxable sale
Italy	22%	10% / 5% / 4%	€85,000 (regime forfettario)
Ireland	23%	13.5% / 9%	€85,000 (goods) / €42,500 (services)

Sources: Each country's national tax authority and applicable VAT Directive transposition legislation, verified July 2026.

Portugal's €15,000 threshold is the lowest in the table — significantly below Ireland's €85,000 or Italy's €85,000 regime forfettario limit. Businesses operating across multiple EU countries should take note: a turnover level that keeps you exempt in France or Ireland may make you fully taxable in Portugal.

SAF-T (PT) and Certified Software: What You Need to Know

Portugal's SAF-T (PT) requirement is one of the most comprehensive e-invoicing frameworks in the EU. Every IVA-registered business must comply.

SAF-T (PT) requires businesses to:

• Use AT-certified invoicing software (list published and maintained by the AT)
• Generate invoices with an ATCUD code (unique document identifier assigned via AT's webservice)
• Embed a QR code on every invoice linking to the ATCUD and core invoice data
• Export a SAF-T XML file covering all sales invoices, which the AT may demand at audit

The AT publishes the official list of certified software at portaldasfinancas.gov.pt. Using uncertified software — including basic spreadsheet invoicing — is a compliance breach subject to fines.

KARR is certified-invoicing-compatible for Portugal, generating ATCUD codes, embedding QR codes on invoices, and producing SAF-T (PT) XML exports directly from your ledger. KARR also applies the correct IVA rate (23%, 13%, or 6%) automatically based on the product or service category you assign, and tracks your cumulative turnover against the €15,000 threshold — alerting you before you breach it and trigger a registration obligation.

After Registration: Ongoing IVA Compliance

Registering is the start, not the finish. Here are the key ongoing obligations for IVA-registered businesses in Portugal.

File periodic IVA returns via the Portal das Finanças on the schedule set by the AT (monthly or quarterly, based on the €650,000 turnover threshold above).

Pay IVA due by the same deadline as the return. Late payment attracts interest at statutory rates set by the AT.

Maintain accounting records for at least 10 years under the Portuguese Commercial Code.

Submit annual SAF-T accounting file if requested, and maintain the monthly/quarterly invoicing SAF-T export capability at all times.

Report intra-Community supplies via the Declaração Recapitulativa (EC Sales List equivalent) if you supply goods or services to VAT-registered customers in other EU member states.

Deregister by submitting a Declaração de Cessação de Atividade if you cease trading or fall permanently below the €15,000 threshold and elect to reclaim the Article 53 exemption.

KARR's Portugal compliance module prepares your periodic IVA return directly from the same ledger you use for invoicing and expenses — no manual reconciliation, no double entry. The practice dashboard lets accountants manage multiple Portuguese clients from one screen, with batch SAF-T exports and return-ready summaries.

Voluntary Registration: When It Makes Sense

Business owners below the €15,000 threshold can voluntarily register for IVA. This is often the right choice when your customers are themselves IVA-registered businesses (B2B), because they can recover the IVA you charge — meaning it costs them nothing — while you gain the ability to recover input IVA on your purchases.

Voluntary registration makes sense if:

• You make significant capital purchases (equipment, premises fit-out) where input IVA recovery is valuable.
• Your customers are all VAT-registered and can fully recover IVA charged to them.
• You trade cross-border within the EU and need a valid PT VAT number for intra-Community transactions.

Voluntary registration means accepting all ongoing compliance obligations — certified software, periodic returns, SAF-T — from day one.
