Latest news and stories about tax compliance in finance in Portugal for expats and residents.
The Tax and Customs Authority (Autoridade Tributária e Aduaneira or AT) announced it is changing its communication model with taxpayers. The agency will stop using traditional envelope-letters for official correspondence as part of a broader modernization of its digital services.
Sovos, a tax‑compliance and electronic‑invoicing firm, launched Mirror Visibility, a tool that compares companies' billing data in real time with records held by the Tax Authority to flag discrepancies. The product aims to speed detection of mismatches and support corporate compliance ahead of audits; firms using electronic invoicing may gain earlier warning of reporting issues. Accountants and finance teams should consider whether the tool fits existing reporting systems.
Sovos is a technology company that specialises in electronic invoicing and tax-compliance software and services; it presented a tool called Mirror Visibility that analyses financial data in real time to spot tax discrepancies. For businesses operating in Portugal, using such tools can speed up error detection and lower the risk of audits or penalties.
Electronic invoicing is the issuance and exchange of invoices in a structured digital format that accounting and tax systems can process automatically. It helps companies and tax authorities detect mismatches faster — as Sovos' Mirror Visibility aims to do — and many countries use or require e‑invoicing to improve tax reporting and compliance.

From 1 January 2026 the amendment to the VAT periodicity regime shifts the onus from the Tax and Customs Authority to the taxpayer: rather than receiving an official reclassification, taxpayers must now submit a formal declaration to request a change of periodicity. The declaration should identify the taxpayer (tax identification number and contact details), state the current and requested VAT periodicity classification, give the intended effective date and the legal or factual reasons for the change (for example a change in turnover, accounting regime or business structure), and attach any supporting documents required by the Authority.
In practice the declaration is normally submitted electronically via the Authority’s online portal and must be signed with the appropriate digital signature or authentication method. Before filing, reconcile turnover figures and previous VAT returns so the requested periodicity is consistent with statutory thresholds; indicate whether the change is temporary or permanent; and keep a copy of the submission receipt. Late, incomplete or absent declarations can lead to the Authority maintaining the previous classification, administrative penalties or cash‑flow disruption from an unexpected reporting frequency. For most taxpayers — and especially for expats or businesses undergoing structural change — it is advisable to consult an accountant or tax adviser to check eligibility, prepare supporting evidence and confirm the correct form fields and deadlines on the Authority’s website.
The tax administration aims to tighten oversight of digital platforms due to suspicions of fake invoicing used to reduce VAT payments, according to a government report.

Investigations by the Tax and Customs Authority (AT) revealed complex schemes involving long chains of entities designed to evade VAT and corporate income tax. The AT plans to develop new risk indicators for early detection and conduct nationwide field operations to address these irregularities, which have also been identified in sectors ranging from logistics and construction to wholesale trade.

The Council of the European Union has reached a provisional agreement to bolster the fight against VAT fraud through increased cooperation between member states and European investigative bodies. The agreement provides initial approval for new rules to intensify collaboration with the European Public Prosecutor's Office (EPPO) and the European Anti-Fraud Office (OLAF), granting them more direct access to essential VAT data on cross-border commercial transactions. According to the European Commission, this type of crime costs member states and the EU budget between 12.5 billion and 32.8 billion euros annually, often linked to organised crime networks. The measures, which involve revising the regulation on administrative cooperation in the field of VAT, must still be validated by the European Parliament, with formal adoption expected in July 2026.
