Receiving a letter from the Spanish Tax Authority (Agencia Tributaria) can sometimes be confusing, particularly when the correspondence relates to penalties, surcharges, VAT compliance, or OSS obligations.

This guide explains the most common types of Spanish tax notifications and helps you understand when action is required.

💡 Why Have I Received a Letter?

The Spanish Tax Authority issues many different types of notifications throughout the lifecycle of a VAT registration.

Some letters are purely informative, while others may require:

📌 Payment

📌 Additional information

📌 Supporting documentation

📌 A response or explanation

Understanding the type of notification is important before taking any action.

⚠️ Understanding Penalty Proposals vs Final Penalty Decisions

One of the most common areas of confusion relates to penalty notifications.

First Letter – Proposal

The first notification is often a proposal or initiation of proceedings.

This letter:

✅ Explains the issue identified by the tax authority

✅ Gives the taxpayer an opportunity to respond

✅ Does not normally include a payment document

✅ Does not generally require payment at this stage

Second Letter – Final Decision

If the tax authority decides to proceed, a final decision may be issued.

This notification:

✅ Confirms the outcome of the review

✅ States the final amount due

✅ Includes payment instructions or payment documentation

✅ Requires payment where applicable

📌 In general, payment is only required once the final decision has been issued.
