Portugal VAT Compliance Guide
Portugal applies a standard VAT (IVA) rate of 23% (reduced 13% / intermediate 6%) under the CIVA (Código do IVA). The registration threshold for domestic turnover is €14,500 per year — one of the lowest in the EU. Since 2024, mandatory e-invoicing through the Autoridade Tributária (AT) portal applies to B2G transactions, with phased expansion to B2B. Businesses must also transmit invoice data to AT in real time via certified invoicing software (Portaria 363/2010).
Portugal has been an early mover in digital tax compliance. Certified invoicing software — software that must be approved by the Autoridade Tributária and that transmits invoice hashes to AT at issuance — has been mandatory since 2013, making Portugal one of the first EU countries to enforce a form of continuous transaction control (CTC). The €14,500 registration threshold is the lowest headline threshold in the EU, which means small service businesses cross it quickly. The 2024 B2G e-invoicing mandate (Portaria 195/2024) extends the structured e-invoice requirement through the AT portal, and B2B expansion is on the roadmap. The practical burden is ensuring that every invoice is issued from certified software, carries the correct AT validation hash, and is transmitted on time.

Filing Requirements
VAT return (declaração periódica de IVA)
Monthly for turnover above €650,000; otherwise quarterly. Filed via the Portal das Finanças, with payment due by the 20th of the second month following the period. An annual VAT return (declaração anual) is also required.
Certified invoicing software (Portaria 363/2010)
All businesses using invoicing software must use a system certified by AT, which transmits a cryptographic hash of each invoice to AT in real time. The invoice bears a unique AT validation code.
VIES / Intrastat
VIES recapitulative statement filed monthly with the periodic return. Intrastat required above annual intra-EU trade thresholds.
E-Invoicing Status
Mandatory B2G e-invoicing through the AT portal has been in force since 2024 (Portaria 195/2024), covering all public-sector suppliers. The certified-invoicing-software requirement (since 2013) already functions as a real-time CTC layer for the private sector. Expansion of structured B2B e-invoicing through the AT e-invoice portal is underway, aligning with the EU ViDA direction.
Key Deadlines
VAT return + payment: 20th of the second month following the period (e.g. 20 May for the March period). Certified-software transmission: at the moment of invoice issuance. AT e-invoice (B2G): within the deadline set for each contract, typically 5–10 days.
How Nika Helps
Nika captures every supplier invoice — supplier VAT (NIF) number, the correct Portuguese VAT rate (23% / 13% / 6%), net, VAT, gross — and files the original PDF the day it arrives, from {price} per processed invoice. That gives the accountant clean, complete records to reconcile against AT transmissions and file the periodic VAT return. Nika does not transmit to AT or file the return itself — that remains the accountant's responsibility.
Why is the Portuguese registration threshold so low?
The €14,500 threshold has been stable for years and reflects Portugal's policy of bringing small businesses into the VAT net early. Service businesses in particular cross it quickly — monitor cumulative turnover monthly, because registration is retrospective to the date the threshold was crossed.
What does "certified invoicing software" mean in Portugal?
It means the software has been approved by the Autoridade Tributária and transmits a cryptographic hash of each invoice to AT in real time, printing a unique AT validation code on the invoice. Plain spreadsheets or uncertified tools do not satisfy this obligation.
