Latest news and stories about tax compliance 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.
