Updated over 12 months ago

The e-fatura portal [link], designed to encourage invoice issuance and curb tax evasion, also unlocks tax incentives, known as deductions in Personal Income Tax (IRS). This guide elucidates the process of registering deductible expenses on the e-fatura portal, ensuring taxpayers benefit from eligible deductions from personal income tax (IRS).


What are tax deductions and e-fatura?

  • The e-fatura system facilitates the transmission of purchase data directly to the Tax and Customs Authority (AT), crucial for IRS personal deductions.

  • Deductions cover various categories of personal expenses such as health, education, housing, nursing homes, family expenses, and partial VAT refunds on specific services.


Deduction categories and weights

  • Categories like health, education, and housing carry different deduction weights.

  • Correct validation ensures taxpayers maximize deductions on expenses like transport passes, accommodation, restaurants, workshops, beauty salons, and veterinary services.


Invoice validation deadline

  • According to the IRS tax calendar, invoices must be validated by February 25 of the following year.

  • Timely validation ensures taxpayers have a comprehensive overview of expenses and allows corrections before the deadline.


How can taxpayers validate their invoices?

(1) Register with Tax Authority’s Portal: New users need to register on the Portal das Finanças. Access passwords are sent to the registered address.

(2) Access e-fatura: Visit the e-fatura homepage, navigate to "Despesas dedutíveis IRS," click on "Consumidor," and enter the Tax Authority’s portal password. The access can also be done through the Tax Authority’s portal.

(3) Verify accumulated expenses: Check accumulated expenses associated with the taxpayer’s tax number (NIF), categorized by sector.

(4) Validate outstanding invoices: If outstanding invoices exist, the portal notifies the taxpayer. Validate them by clicking on "Complementar Informação Faturas" or “Resolver Pendências.”

(5) Associate medical prescriptions: For health expenses with a 23% VAT rate, click on "Associar Receita." Indicate if a medical prescription is available along with the expense amount.

(6) Enter invoices manually: In case of missing invoices, manually enter them via "Faturas," "Registar Faturas," filling in essential details.

(7) Confirm validation: Regularly check e-fatura to ensure correct entry of invoices. Adhere to IRS deadlines for submission.


Self-employed workers

  • For self-employed workers, validate invoices indicating whether expenses are related to professional activity.

  • These designated business-related expenses must be essential to exercise their professional activity.

  • Portuguese business-related expenses can be considered upon VAT quarterly statements, granting freelancers the opportunity to have the VAT from these purchases reimbursed (input VAT).

  • Under the simplified regime, freelancers are required to provide proof of expenses to make up at least 15% of expenses related to the profession.

  • Validation is critical for self-employed workers with self-employment (category B) income to avoid losing potential VAT refunds.


By actively participating in the e-fatura system, taxpayers enhance their IRS deductions, ensuring accurate validation of invoices and adherence to submission deadlines. Self-employed workers, in particular, should meticulously validate professional expenses to optimize their entitled deductions and avoid financial losses. Regular monitoring and compliance with IRS guidelines are key to a successful e-fatura experience.
