Invoice requirements for intra-Community sales from Portugal
Updated 28 Oct 2026 · Legal references to the Portuguese VAT Code and RITI (unofficial English translation)
Short answer
Besides the general elements of VAT Code Article 36(5), it must show the supplier's number with the PT prefix, the customer's VAT number with its country prefix, the reason why VAT is not charged and, for goods, the place of destination. For goods it must be issued by the 15th day of the following month. Where the customer is liable, the invoice must include «IVA - autoliquidação» (reverse charge).
Intra-Community supply of goods
An invoice for a supply exempt under RITI Article 14 must also contain (RITI Article 27(5)):
- the supplier's tax identification number preceded by
PT; - the customer's VAT identification number with the prefix of the Member State that issued it (Greece:
EL); - the place of destination of the goods.
It must state the reason for not charging VAT (Article 36(5)(e)), e.g. «Isento — artigo 14.º, n.º 1, alínea a) do RITI», and be issued no later than the 15th day of the month following the month in which the goods were made available to the customer, for the total value of the supply (RITI Article 27(2) and (3)).
B2B services to a customer in another Member State
The invoice has no Portuguese VAT, shows the customer's VAT number with prefix, the reason for non-taxation (e.g. «Artigo 6.º, n.º 6, alínea a) do CIVA») and the words «IVA - autoliquidação», required whenever the customer is liable for the tax (Article 36(13)).
Before issuing
Validate the customer's VAT number in VIES and keep the proof. These sales are also reported in the recapitulative statement.
