# DEHú notification alerts and 10-day deadline | aiDEHú > Note AEAT or Social Security notices, count the 10 calendar days you have left, and get an email alert before they expire. No certificates. - **Source (source):** https://aistohire.com/dehu-notification-alerts-10-day-deadline-187 - **Platform (platform):** AIstoHire - **Language (language):** en - **Updated (updated):** 2026-10-10 ## In summary - Your DEHú inbox under control and with no surprises - For SMEs and self-employed workers required to deal with the Administration electronically: if you do not log in to open a notification within 10 calendar days, it is deemed served by rejection and the deadline to respond or appeal still runs. aiDEHú records every notice you receive, counts the days remaining, and emails you before they run out. No certificates or powers of attorney. - The 10-day counter, with the calculation in view: Each pending notification shows the days remaining and the exact due date, counted in calendar days from when it was made available, and a traffic light that organizes the inbox: green with margin, amber at 3 or 4 days, red at 2 or fewer, black when it has already expired. It is not a black box: you see the whole calculation, and it is labeled as an indicative calculation, because the actual deadline depends on the procedure. - Staggered alerts to you and your adviser, with a log of what was sent: An email when the notice is received and reminders on days 3, 6, 8, 9, and 10, with the subject line already written: '[AEAT] Due in 2 days — MONTAJES SL'. You can add recipients — your partner, your accounting firm — and decide who receives everything and who only gets urgent items, and turn each reminder on or off. Every send is logged with its date and recipients; and those that did not go out are too, with the reason. - Check-up round and exportable history: Every so often — weekly, fortnightly, or monthly, you choose — the app reminds you to go into DEHú and check, and with one tap you record that the inbox was clean. If you find something that had not arrived, you add it manually right there. All of that, along with the notifications and alerts sent, can be downloaded as CSV or PDF: it is your proof of diligence the day someone asks for it. ## What if right now you had a notification waiting for you and you didn't know it? Since Law 39/2015, the AEAT, Social Security, the DGT, your autonomous community, and your town hall deposit their notifications in DEHú, and the 10-calendar-day countdown starts the day they make them available to you, whether you read them or not. aiDEHú does not go into your inbox or ask you for the certificate: you pass it the notice that arrives by email — by pasting it with one tap or forwarding it to that company's dedicated address — and the app extracts the issuing body, reference, and date, calculates the due date, and reminds you by email to go in and open it. And since DEHú sends that notice 'as far as possible' and does not guarantee it, it also reminds you from time to time to go and check, and keeps a dated record that you did. ## What you need so you never miss a deadline Monitoring, counting, and alerting do not need artificial intelligence: they are code rules, deterministic and free. The only thing that uses credit is asking Elena to explain a PDF to you, and the price is visible before you click. ### The 10-day counter, with the calculation in view Each pending notification shows the days remaining and the exact due date, counted in calendar days from when it was made available, and a traffic light that organizes the inbox: green with margin, amber at 3 or 4 days, red at 2 or fewer, black when it has already expired. It is not a black box: you see the whole calculation, and it is labeled as an indicative calculation, because the actual deadline depends on the procedure. ### Staggered alerts to you and your adviser, with a log of what was sent An email when the notice is received and reminders on days 3, 6, 8, 9, and 10, with the subject line already written: '[AEAT] Due in 2 days — MONTAJES SL'. You can add recipients — your partner, your accounting firm — and decide who receives everything and who only gets urgent items, and turn each reminder on or off.

One minute, no certificates or powers of attorney. You can monitor several companies from the same account. 2. **Pass it the notice when it arrives** — Copy the notice email and paste it into the app, or forward it to that company's dedicated address. The issuing body, reference, and date made available are extracted, and the counter starts. If the notice never arrives, you can add the notification manually. 3. **Open it in DEHú and mark it** — You copy the reference, go to dehu.redsara.es with your certificate or Cl@ve, and open it yourself. You come back, mark it with one tap, and the counter stops. If you want to understand what they are asking of you, upload the PDF and it summarizes it in plain language. ## Frequently Asked Questions ### Do I have to give you my digital certificate or sign a power of attorney for you? No, and we will never ask you for it. aiDEHú does not log in to DEHú, does not store certificates, and does not appear or open notifications on your behalf. This is deliberate: opening a notification starts the response clock, and that decision is yours alone. The app monitors the notices you send it, keeps track of the days, and tells you what to do and where; you are the one who goes in to open it, with your certificate or your Cl@ve. ### How does the app find out that I have a notification? Through the courtesy notice that the Administration sends to your email. When it arrives, you paste it into the app with one tap or forward it to that company's dedicated address, and the issuing body, reference, and date are extracted; anything that cannot be extracted stays 'to be confirmed' and you complete it if you know it. You can also add the notification manually. And we say it everywhere: DEHú sends that notice 'as far as possible' and does not guarantee it, so the app does not promise to catch everything. That is why the periodic check-up round exists. ### Does the 10-day counter count as a legal deadline? It is a tool to help you organize yourself, not legal certainty, and the app says so alongside each calculation. It counts 10 calendar days from the date it is made available, using the Spanish calendar, and shows you the whole calculation so you can check it. Some procedures have their own rules, and if the date had to be estimated from the email itself, it is marked as estimated so you can correct it. Neither that calculation nor the AI-generated summaries are legal or tax advice. ### Does monitoring my deadlines use AI credit? No. The counter, the traffic light, the email alerts, the inbox, the check-up round, the history and its export are code rules: they do not spend a single token. The only thing that uses credit is asking Elena to read a PDF that you have downloaded and uploaded yourself, and before it runs you see the estimated cost and your remaining balance. There is never any automatic charge. - [Blog](https://aistohire.com/dehu-notification-alerts-10-day-deadline-187/blog) ## About the platform **aiDEHú — Monitoring of DEHú notification alerts and deadlines** — an app by AIstoHire.
