The expiration of tax procedures is the automatic termination of a case (limited verification, management, or inspection) when the tax authorities fail to resolve it within the legal timeframe, generally six months.
In practice, expiration protects you against prolonged or irregular actions and strengthens your legal certainty.
At Resitax, your tax advisor in Mallorca, we check if your file has exceeded deadlines and how to use that expiration to your advantage.
The key to the Supreme Court's new criteria on the expiry of tax proceedings
The essence of this new doctrine lies in the expiry of tax procedures, such as limited checks or administrative procedures.
The time limit: six months to resolve
Most tax procedures must be resolved within six months.
If the Tax Agency fails to do so within that period, the procedure is considered expired.
Therefore, the proceedings must be archived and the file declared null and void.
A common practice of the Tax Agency
Until recently, the Spanish Tax Agency (AEAT) would often allow a procedure to tacitly expire.
Then, it would open a new one—for example, a full audit—regarding the same tax and period.
However, it made no formal mention of the previous expiration.
With the new ruling, this practice is now invalidated.
The consequence: nullity of the second procedure
The importance of this ruling is enormous. If the Administration does not comply with the express declaration of expiry and, even so, initiates a new inspection, the Supreme Court considers that:
- The taxpayer's legal certainty is violated by maintaining an ambiguous situation.
- There is a simultaneity of incompatible procedures (the one that expired and the new one), which renders the second act null and void.
What does it mean in practice?
Simply put, if the tax authorities opened a case against you that expired without formal notification, and then initiate another case for the same facts, that second case is null and void.
Therefore, you can challenge the action and defend your rights.

This ruling represents an exceptional defense tool for the taxpayer, as it obliges the Administration to act transparently and strictly respect legal deadlines.
At Resitax, we recommend the following:
Check your notifications
If your audit or management procedure has lasted more than six months and you have subsequently received another assessment or inspection for the same matter, contact us immediately.
We will analyze whether there are grounds for annulment.
Do not ignore administrative silence
If a procedure takes longer than expected, it can actually work in your favor.
However, it's essential to manage it correctly and with expert advice.
At Resitax, we are ready to analyze your case and apply this new Supreme Court.
Our goal is to challenge any action by the Spanish Tax Agency (AEAT) that fails to comply with the obligation to declare the expiration of the tax liability.
