Receiving a notification from the Tax Agency (Hacienda) can cause anxiety and worry, especially if you're not familiar with tax procedures. However, it's important to know there are clear steps you can follow to defend yourself properly and resolve any situation the tax authorities raise. This article guides you through the process, explains the differences between types of notifications and the possible implications for the property sector, and gives you practical tips for handling these situations.
1. What is a notification from the Tax Agency?
A notification from the Tax Agency is an official document the Spanish Tax Agency sends to taxpayers to communicate a discrepancy, request or information related to their tax obligations. These notifications can arise for various reasons, such as errors in a tax return, non-payment or the detection of suspicious financial movements.
In the property sector, the Tax Agency commonly issues notifications related to the purchase and sale of properties, the declaration of rental income tax or Wealth Tax. If you own a home or are involved in property transactions, you should pay particular attention to these communications.
2. Types of Tax Agency notifications
There are different types of notifications you may receive from the Tax Agency, each with specific implications. Knowing the differences will help you understand how to act.
Request for information notification
This type of notification asks for additional information about your tax situation. For example, if you've recently sold a property, the Tax Agency may ask you for documents to verify the transaction and the taxes paid.
Assessment notification
In this case, the Tax Agency notifies you that it has detected a discrepancy in your tax return and has recalculated the amount payable. This usually means an adjustment to the taxes declared, and you may have to pay an additional amount.
Seizure notification
When there is an unpaid tax debt and you haven't responded to previous notifications, the Tax Agency may seize assets or bank accounts. In the property sector, this can include a precautionary attachment of a property.
Tax inspection notification
The Tax Agency may open an inspection of your tax returns if it believes there are signs of fraud or irregularities. In the property sector, a tax inspection can look into anything from declared rental income to the gain made on the sale of a home.

3. Key differences between types of notification
3.1. Request vs. Assessment
A request is simply a request for additional information and doesn't necessarily mean a penalty, whereas an assessment means the Tax Agency has found a discrepancy and is demanding an additional payment.
3.2. Seizure vs. Tax inspection
Seizure is the most drastic action the Tax Agency can take to collect a debt, whereas a tax inspection is a more thorough and detailed procedure that may involve reviewing all your income and assets.
4. How should you act when you receive a Tax Agency notification?
Receiving a notification from the Tax Agency doesn't always mean there's a serious problem, but it does mean you need to act diligently. Here are some practical steps to defend yourself.
Step 1: Stay calm.
The first piece of advice is not to panic. It's normal for a Tax Agency notification to cause stress, but most situations can be resolved easily if you follow the right procedures.
Step 2: Read the notification carefully
The notification will clearly state the reason for the contact and tell you what action to take. It's essential to read the document carefully and understand whether it's a request, an assessment or an inspection.
Step 3: Review your tax return
If the notification is due to an error in your tax return, carefully review what you submitted. You may have made an unintentional mistake that you can correct without further consequences.
Step 4: Gather the necessary documents
If the Tax Agency asks for additional information or documents, such as invoices or property purchase contracts, make sure you gather all the relevant documents. In many cases, providing the right documents can resolve the issue quickly.
Step 5: Seek professional advice
If you're not sure how to proceed or the case looks complicated, it's advisable to get help from a tax advisor. These professionals know the Tax Agency's procedures and can guide you to avoid mistakes that make the situation worse.
Step 6: Respond within the deadline
All Tax Agency notifications have a response deadline. If you don't respond in time, you could face additional penalties. Make sure you meet the deadlines, even if you disagree with the notification.
