How to pay part of a debt to the Finanças

Some bills accept a partial payment. On the Portal, open the bill's detail (VER DETALHE), follow the link to the partial-payment request, enter the amount and press CONFIRMAR: a payment reference is generated for that amount. The rest stays owed.

Step by step

1. Sign in and open the list of payments due, at sitfiscal.portaldasfinancas.gov.pt/inffin/pagamentosDecorrer.html.
2. On the bill's line, press VER DETALHE (see detail).
3. On the bill's detail page, follow the link to the partial-payment request.
4. The list that opens holds the bills that accept a partial payment. On yours, press EFETUAR PEDIDO (make request).
5. Enter the amount you want to pay now. It has to be less than the bill's total.
6. Press CONFIRMAR. This generates a real payment reference for that amount.
7. Pay with the reference, at a Multibanco ATM, in online banking or by MB WAY.

Before you ask

• Only the bills on the partial-payment list accept it. If yours is not there, the Portal does not offer this route for it.
• Fines (coimas) cannot be paid in parts.
• Whatever is left stays owed and, after the deadline, accrues late-payment interest.
• If you need more time to pay all of it, compare with a payment plan.

With tudo certo.

tudo certo. shows, for each bill, whether the Portal accepts a partial payment, takes the tab to the form and fills in the amount. The click on CONFIRMAR is always yours.
