Understanding Contractor Invoice Requirements in Portugal
In Portugal, contractors must adhere to specific invoicing requirements to ensure compliance and streamline their billing processes. These requirements are governed by the VAT Code, which mandates that invoices include essential elements such as the date of issue, sequential invoice number, ATCUD (Unique Document Code), and the tax identification numbers (NIF) of both the issuer and recipient. Additionally, invoices must provide a detailed description of the goods or services provided, along with applicable VAT rates and amounts.
A unique aspect for contractors in the construction sector is the "IVA – autoliquidação" regime, where invoices are issued without VAT liquidation if the service acquirer is a VAT taxpayer. This regime is crucial for avoiding VAT errors, which are common in the sector due to varying rates for different types of construction work. Invoices must also include the contractor's social denomination and license number for compliance with industry-specific regulations.
