July 31, 2026, is approaching, and everyone is longing to disconnect. Suitcases are packed, the business is about to close, and the teams are preparing for their well-deserved summer break. However, at Ruiz & Associates, we always issue the same last-minute technical warning: hanging a “Closed for Vacation” sign (using the courtesy days) on your office door will not stop the Single Enabled Electronic Address (DEHú) mailbox from being filled. 📪

If the Tax Agency sends you a formal request in mid-August and no one opens it, the law stipulates that after 10 calendar days it is considered “notified.” At the end of September, your company could face penalties for non-payment or loss of the deadline for filing an appeal. The legal solution exists and it’s called a grace period.

⚖️ What are the courtesy days of the Treasury and how do they work?

Courtesy days are a right that allows companies and self-employed individuals required to receive electronic notifications to designate up to 30 days per calendar year during which the Spanish Tax Agency (AEAT) will not be able to deposit notifications in their digital mailbox. 🛡️

For this shielding to be effective for this month of August 2026, you must know the rules of the technical game:

• Minimum notice: Courtesy days must be requested at least 7 days before the first day you wish to disconnect. If you request it today, July 31, your protection will not begin until next week.
• Flexibility: You are not required to request the 30 consecutive days. You can break them up into weeks or long weekends, adapting them to your actual vacation schedule.
• Restrictive effect: It only stops notifications from the Spanish Tax Agency (AEAT). Other agencies (such as Social Security or regional governments) have their own systems that should be reviewed independently to maintain the legal security of their assets.

🤖 The danger of automatic algorithms in summer

You might think that tax inspectors also take a break in August, and that’s true. The real danger in 2026 isn’t the human factor, but the Tax Agency’s algorithmic auditing. Following the filing of income tax returns in June and the corporate tax returns just a few days ago, the AEAT’s servers are processing millions of cross-referenced data points automatically. 📊

If the system detects a discrepancy in your second-quarter tax returns or in your mandatory electronic invoice history, the request is issued and sent automatically, regardless of whether it’s a holiday or the middle of August. The algorithm doesn’t go to the beach.

You can carry out the application procedure directly by accessing the notifications area of the Tax Agency’s Electronic Office.

🛡️ What happens if you receive a notification without activating Free Days?

If you’ve been careless and the tax authorities send you a notification while you’re away, being proactive upon your return will be your only option. Ignoring the email won’t work.

Upon returning in September, if you discover an unanswered request, it’s time to invoke the right to claim error or allege justifiable technical issues if the platform experienced outages. However, litigating against a missed deadline due to sheer holiday negligence is a treacherous path best avoided through rigorous planning today. ✅
