Notifications from the Tax Agency (Hacienda) go directly to you. Xolo doesn't receive them and can't manage them on your behalf, so checking them regularly is your responsibility. The same applies to notifications from Social Security: both authorities communicate with you individually.
It's important to stay on top of them: if a notification goes unopened within its deadline, it can be considered delivered anyway and lead to surcharges and interest.
To access these notifications, you need a means of electronic identification. We recommend a digital certificate (you can also use Cl@ve or DNIe). 👉 How to request your digital certificate
If you receive a notification and aren't sure how to interpret it, write to us at ayuda@xolo.io, and we'll help.
