The list
What is overdue goes at the top, in black
A single list, sorted by what falls due first and grouped by how pressing it is: overdue items first, because they are the only ones already costing money.
A suggestion, not an imposition
Self-employed or company, VAT (IVA) scheme, employees, rented premises: from your answers we suggest the forms for the year and the reason for each one. You remove and add. And if it has a date, it fits: the town hall fee too.
How long is left, in days
“Faltan 6 días” (6 days left) is easier to take in than a date. And if it is already overdue, it says so: “Venció hace 2 días” (was due 2 days ago).
Tick it and forget it
One tap and it moves to filed, with the date you did it. Whatever does not concern you is marked “no me aplica” (does not apply to me) and stops bothering you.
In your own words
The form, the period, the amount and your notes, with a link to the official page of each form. The suggestion is a starting point: what stays on the list is up to you.
Reminders
It reminds you before, not after
By default, a week before each due date and the day before. Enough time to gather your invoices or to write to your gestoría (tax adviser’s office), which is when a reminder is actually useful.
On the days you choose
Two by default, because more would be noise. If you want others, a daily reminder as it gets close, or none at all, you can change it for all of them or just for one.
Worked out by your device
No server sends them: they are worked out from what you have noted down, so they work offline and nobody outside needs to know what you owe.
With the app closedSoon
On your phone they will go off even with the app closed. In the browser, while you have the tab open.
Privacy
What you owe is nobody else’s business
What you note down is stored on your device and opens offline. There is also a copy in your account so you can see it on all your devices, and if you do not want it, you turn it off and it is deleted from the server.
Reminders go through nobody
They are worked out on your device, so the server does not need to know what you file, when or for how much.
No ads, and nothing without permission
No advertising and no advertising cookies. Google Analytics statistics, here and in the app, only if you accept them, and they never see your obligations.
Delete means delete
Your account, together with the copy of everything you have noted down, is deleted from within the app itself, on the spot. No writing to anyone, no waiting for a reply.
Where
On your computer and in your pocket
The same list on both, through the copy in your account. On the big screen you note things down calmly; on your phone is where the reminder arrives.

The official information, at hand
Every form, every deadline and where it comes from
The tax calendar for the year, a guide to each form with links to the official website, and examples of who files what. All copied from the official calendars, with the date they were checked.
Upcoming due dates (Agencia Tributaria and Seguridad Social)
From the official taxpayer’s calendar. In the Canary Islands, the Basque Country and Navarre the deadlines are different: they are in their own calendar.
- 2026 tax calendar The 164 deadlines of 2026 in Mainland Spain and the Balearic Islands, month by month: the form, the period and the last day, copied from the official calendar. In .ics and .json.
- Forms Guides to 104 forms of the AEAT, the Canary Islands, the foral tax authorities and the Seguridad Social: who files them, their 2026 deadlines and their official links.
- Examples 7 made-up profiles and the 2026 calendar that Mis Obligaciones’s rules give them: self-employed under direct assessment and under modules, companies, the Canary Islands, Bizkaia and Navarre.
- Filing late What it costs to file a Hacienda form late or pay the Seguridad Social late: 1% per month, 15%, the €200 penalty and the 10% and 20% surcharges.
- Glossary What an autoliquidación, the 70% rule, REDEME, SII, IGIC, the Concierto Económico or RETA are, explained in two sentences with their official source.
Questions
Before you open an account
Does it file the forms for me?
No. Mis Obligaciones suggests your calendar, reminds you before things fall due and takes you to the official page of each form, but the filing is done by you (or your gestoría, your tax adviser’s office) on the relevant authority’s website. It does not connect to the Agencia Tributaria (AEAT, the Spanish Tax Agency) or to the Seguridad Social, and it is no substitute for an adviser. Marking something as filed here is a note for yourself, not an official step.
Does it tell me which forms apply to me?
It suggests the ones that usually apply to someone like you, with the reason for each (“you have employees, so the 111”), based on your answers and on the official calendar of your tax authority: the national one, the Canary Islands one or the foral one (Basque Country and Navarre). It is a suggestion, not advice: your case may have exceptions that a questionnaire cannot see, so you review it before accepting it and, if you have an adviser, you show it to them.
How much does it cost?
Today, nothing. If one day there is a paid plan it will be explained here and in the terms, and whatever you have already noted down will still be yours.
Do I need a connection?
Not for what matters: what you note down is on your device and the reminders are worked out by it. You need a connection to sign in on a device for the first time and for the copy to reach your other devices.
Does it sync between my devices?
Yes: what you note down is copied to your account and you have it on every device you sign in on, merged field by field, so changing one thing on your phone and another on your computer overwrites nothing. If you would rather everything stayed only on each device, turn the copy off in Settings and it is deleted from the server.
Who can see what I note down?
You. The copy travels encrypted and is stored on the server, where technically whoever runs it could read it: that is why it can be turned off, and why reminders do not go through it. It is not sold, not shared and not used to train anything. It is all in the privacy policy.
When is it coming to iPhone and Android?
It is on the way. Today you can use it in the browser, where reminders go off while the tab is open; on your phone they will go off even with the app closed.
Why is everything black and white?
Because the only thing that should stand out on the screen is what is late. With no colours competing, urgency is read in the black: the darker, the less it can wait. And so that it does not depend on that alone, each status also has its own icon and its own word.
What is left for you this quarter?
Open your account, note down the first form with its date and forget about it until it reminds you.
