Registering the company is the easy part.
What follows requires rather more attention.

Ongoing accounting, tax compliance, corporate advisory, and regulatory support for non-EU-owned companies operating in Portugal. We handle the filings, the bank queries, and the tax authority correspondence — so you can focus on the business.
Problems We Fix in Portugal
Portugal's company registration process asks almost no questions.
The tax authority asks them later.
The Portuguese commercial registry does not scrutinise your business model on the way in. It registers the entity, assigns the number, and moves on. The questions come from the Autoridade Tributária, from your bank, and from the compliance obligations that activate within the first one to three months of operation.
By the time most non-EU founders realize their VAT logic was wrong, or that their CAE codes no longer match what the company actually does, or that the bank wants documentation they hadn't thought to prepare — correcting it costs considerably more than getting it right the first time.

This page is about the getting-it-right part.

Five things that look routine and aren't.

Each item below represents a real, recurring problem — not a theoretical risk.
Problem 1: IVA: where the service is provided, and to whom
Portuguese VAT is not applied uniformly. The same service can attract different treatment depending on whether the client is B2B or B2C, and whether they are based in Portugal, elsewhere in the EU, or outside it entirely.

If the logic is applied incorrectly, the IVA declaration contains a wrong tax base. The error rarely causes immediate disruption — but it compounds across periods and becomes visible on review.
Practical consequence: correcting prior periods requires amended declarations and explanatory submissions. If the authority identifies the error first, penalties apply.
Typical ranges:

  • Errors or inaccuracies in IVA declarations → €150 – €3,750
  • Late filing of declarations → €200 – €2,500 (higher for repeat occurrences)
  • Missing or incorrectly issued invoices (faturas) → €300 – €3,750
Problem 2: CAE codes and what the company actually does
The Código de Atividade Económica codes assigned at registration describe the company's permitted activities. In practice, most companies evolve — new services, new markets, new revenue streams. The codes don't update themselves.

For the first months, this mismatch creates no visible problem. It surfaces when turnover grows, when the bank reviews the account, or when the tax authority examines the filings.
Practical consequence: updating activity codes requires a Declaração de Alteração de Atividade and registry amendments. Until that is done, transactions that fall outside the registered scope can generate questions from both the tax authority and the bank simultaneously.
Problem 3: Banking compliance after account opening
Opening the account is not the end of the banking relationship — it is the beginning of it. Portuguese banks monitor transactions continuously: counterparties, payment references, frequency, and whether the activity pattern matches the stated business description.

When it doesn't match, the bank sends a request. These requests ask for contracts, invoices, and a coherent explanation of the business model.
Companies that cannot produce this documentation promptly face operational restrictions while the explanation is pending.

Practical consequence: the documentation that satisfies a bank compliance query is exactly the documentation that should have been prepared before the account was opened. We prepare it as part of the onboarding process, not reactively.
Problem 4: The mandatory filings in year one
Within the first twelve months, a Portuguese company is required to submit:

  • Declarações periódicas de IVA — monthly or quarterly VAT returns
  • SAF-T (PT) — the standard audit file submitted to the tax authority monthly
  • Modelo 22 — annual corporate income tax return
  • IES (Informação Empresarial Simplificada) — the annual consolidated reporting declaration
Errors in early periods carry forward into the annual filings and become visible as a pattern. The annual IES, in particular, reconciles everything — mismatches between what was declared periodically and what is reported annually generate automatic flags.
Problem 5: The owner's personal tax position
Dividends, management fees, and intra-group service payments do not exist in isolation. They interact with the personal tax residency of the shareholder — and if the two are not aligned, you risk either double taxation or incorrect application of treaty provisions.
Practical consequence: restructuring payment flows retrospectively — after transactions have already been processed — requires amended filings and explanations of decisions that should have been made at the outset. It is possible. It is also avoidable.
Services
Six areas. One consistent point of contact.
(01)
Corporate structure
We design and maintain the corporate form to reflect the actual business — not a template.
The allocation of quotas, the roles of the sócios, the gerência structure, and the Pacto Social are set up to function under growth conditions and withstand scrutiny from banks, counterparties, and regulators. When the structure changes — a new shareholder enters, shares are redistributed, management changes — we handle the amendments through the Conservatória do Registo Comercial and ensure corporate resolutions (atas, deliberações) are properly documented.
(02)
Tax model
Tax logic is established at the start and reviewed as the business grows.
This covers the IRC regime, IVA application (including intra-EU transactions), income distribution strategy, and compliance with European frameworks — ATAD, BEPS, and the substance requirements that matter for international structures. The objective is not to minimise tax on paper. It is to build a model that holds under real turnover and cross-border payments.
(03) EU operations and intra-community VAT

When the company begins trading across the EU, the operational setup matters as much as the registration.

We structure the client and supplier relationships correctly: intra-community VAT (VIES registration and reporting), contract frameworks, invoicing logic, and payment flows. This reduces friction with banks, simplifies expansion into additional EU markets, and ensures the company's filings are coherent when reviewed.
(04) Tax authority correspondence

Контакт с Autoridade Tributária — это регулярный процесс, а не разовая задача.

Мы сопровождаем регистрацию и изменения деятельности (Declaração de Início de Atividade), корректируем CAE по мере развития бизнеса, отвечаем на уведомления (notificações) и выстраиваем позицию компании так, чтобы решения были понятны и защищаемы при проверках.

Corporate changes
As the company grows, its structure changes. Shareholding evolves, management changes, new entities are introduced.
We process these changes through the registry, draft the necessary corporate documentation, and ensure that structural amendments do not inadvertently disrupt the tax or operational model. A change that looks purely administrative often has tax consequences that are worth reviewing before the paperwork is filed.
(06)
Expats and personal tax
Если владелец или команда переезжают в Португалию, корпоративная модель должна быть синхронизирована с личной налоговой позицией.
When a founder or key team member relocates to Portugal, the corporate model needs to be synchronised with their personal tax position.

We handle NIF acquisition, residência fiscal determination, and the structuring of income flows — dividends, management remuneration, intra-group services — to avoid conflicts between jurisdictions and ensure treaty provisions are applied correctly. Portugal's personal tax regime has been in transition in recent years; we stay current on what applies and what has changed.
Three situations where this tends to matter most.
Is this relevant to you?
Situation 1:

You registered recently and aren't certain everything was set up correctly

The registration itself was probably fine. The question is whether the objeto social, the CAE codes, the tax regime, and the IVA logic were set up to match how the company actually operates. If you're not certain — or if the company has evolved since registration — a structured review is faster and cheaper than discovering a problem later.
Situation 2:

You're operating but your bank keeps asking questions

Bank compliance queries after account opening almost always come from the same source: a mismatch between the stated business model and the observed transaction pattern. This is fixable. It requires producing the right documentation in the right format — and adjusting the operational setup so the mismatch doesn't recur.
Situation 3:

You're expanding beyond Portugal and need the structure to support it

A Portuguese company used as an EU launchpad needs to be structured for what comes next, not just for the current moment. Intra-EU VAT, transfer pricing between related entities, substance requirements in each jurisdiction — these are not problems that appear immediately, but they are much easier to address before the structure is fully built than after.
How We Work
Retainer, not project fees.
For companies already operating in Portugal, we work on a monthly retainer basis. This means questions get answered when they arise — not after a new engagement letter has been signed and a project scoped.

The retainer covers ongoing accounting, tax filings, regulatory correspondence, and advisory within the agreed scope. Ad hoc work outside the scope — significant structural changes, contested tax auhority positions, litigation support — is scoped and priced separately.

Starting from €400 / month, depending on transaction volume, structural complexity, and the level of advisory involvement required.

If you're not yet a client but have a specific question or problem, we're happy to have a first conversation without charge.
FAQ: Questions we're asked
  • Q:
    We already have an accountant in Portugal. Why would we need you?
    A:
    A contabilista certificado is a legal requirement in Portugal and handles the filing obligations. What they typically don't provide is advisory on corporate structure, cross-border tax logic, banking compliance, or the strategic questions that arise as the business grows. We work alongside local accountants — or, if preferred, replace them — depending on what the situation requires.
  • Q:
    We received a notification from the Autoridade Tributária. What should we do?
    A:
    Don't ignore it — notificações from the tax portal have response deadlines, and missing them generates penalties independent of whether the underlying matter was serious. Send us the notification and we'll review it. Most are routine; some require a response; a small number require immediate action. We can tell you which category yours falls into.

  • Q:
    Can you help us restructure a company that was set up incorrectly?
    A:
    Yes. We do this regularly. The process starts with a review of the current structure — corporate documents, tax registrations, filing history — and a clear picture of what needs correcting, in what order, and at what cost. Retrospective corrections are usually possible; they are simply less efficient than getting it right the first time.
  • Q:
    We're planning to move to Portugal. How does that affect the corporate setup?
    A:
    Significantly, in some cases. The tax residency of a shareholder affects how dividends and management fees are taxed, which treaty provisions apply, and whether the company's structure is optimal for the new situation. Portugal's personal tax regime has changed materially in recent years. We review the personal and corporate position together before the move, not after.
  • Q:
    We operate across several EU countries. Can you handle the cross-border complexity?
    A:
    Portugal is our primary jurisdiction. For clients with operations in Spain, Germany, Luxembourg, or other jurisdictions where BCA Group has presence, we coordinate across the network. For jurisdictions outside the network, we work with trusted local partners. We're transparent about where we operate directly and where we refer.
