To pay fines online, you must also have a digital certificate or electronic ID to prove your identity.

Once the notification of the fine arrives, you will have a voluntary period of 20 days in which you can pay with a reduction of 50% of the total amount of the fine. After that time, an ordinary period of 25 more days will begin, but in this case, you will have to pay 100% of the amount. 

If you have not paid the fine by that time, it will be sent to the Tax Agency where the amount will be subject to a 20% surcharge.
