The Portuguese government has extended several VAT compliance deadlines under Order No. 78/2025 – XXIV on 6 May 2025, due to recent tax portal access issues caused by power outages in some EU countries and other network disruptions.
The new deadline for reporting invoices related to goods and services acquired in April 2025 is 9 May 2025, extended from the original 5 May deadline. VAT returns for March 2025 (monthly regime) and for the first quarter of 2025 (quarterly regime) are now due by 26 May 2025, with payments due by 30 May 2025. The original deadlines were 20 and 25 May, respectively.
Additionally, the deadline for submitting the VAT return for April 2025 B2B services provided to EU-based recipients (under the monthly regime) has been extended to 26 May 2025, from the original 20 May deadline.
