aiTributos — Tax calendar for self-employed and SMEs · Everything that's due, with the exact date and timely alerts

For the self-employed person and small business that already has an accounting firm but lives with the doubt of whether they're missing something: tell us once how you file taxes and get YOUR calendar of due dates, not the generic AEAT PDF. We alert you before each deadline; filing is still done by your accounting firm.

Do you know what's due next month, or do you wait for someone to remember to alert you?
Your accounting firm files your tax forms, but you don't see the calendar: not what's coming, not when, nor everything it doesn't handle — the expiring digital certificate, the fire extinguisher inspection, insurance, rent —. aiTributos asks you once how you file taxes and turns your calendar for the current and following year into reality with deterministic rules, not with an AI that improvises dates: each due date comes with its exact day, with the shift explained if it falls on a Saturday or a holiday in your region, and with the two dates that matter when there's a payment. And it alerts you by email before each one. It doesn't calculate amounts or file anything: it alerts and gives visibility so you arrive prepared to your accounting firm.
Start freeThe exact dates, the two that matter, and the alerts nobody gives you
It's not a planner you fill in yourself: the calendar is born from your tax profile and recalculates itself when your business changes, without touching what you already marked as done.

Your calendar, not a generic one
You answer in two minutes whether you're self-employed or a company, how you settle VAT, whether you're under modules or direct estimation, whether you have employees, whether you rent a premises with withholding, whether you sell to the EU, whether you're in SII, and when you close the fiscal year. With that, only your obligations appear: VAT (303 and 390), installment payments (130 or 131), withholdings (111, 115, and 123) with their annual summaries (190 and 180), 347 and 349, Corporate Tax (200 and 202), chained annual accounts — prepare, approve, and file —, book legalization, income tax campaign, and Social Security. Each date with its day of the week and, if the deadline has shifted, the reason: 'the 20th falls on a Saturday, so it moves to Monday the 22nd'.

The two dates: direct debit and filing
The most common surcharge isn't forgetting the form: it's preparing it on the 18th when the deadline to direct-debit the payment closed on the 15th. Each due date with a payment has its two dates, and the big day counter counts the one that really pressures you, with the label 'for direct debit' so there's no doubt. And forms that must be filed even if you haven't invoiced anything have a fixed notice on the card and in the email, because the penalty for not filing also exists when the result is zero.

What your accounting firm doesn't handle
Digital certificate, insurance policy, ITV, electrical or elevator inspection, prevention plan, domain and hosting, licenses, agreements: ten templates to set them up by entering only the date, with their recurrence, attachment, and their own alerts. The digital certificate gets special treatment — alerts at 30, 15, and 1 day and a highlighted card — because if it expires, it can no longer be renewed online: you have to request an in-person appointment and it can take weeks.
From doubt to calendar, in three steps
Tell us how you file taxes
Eight or ten questions in business-owner language, one per screen and almost all one-tap. If you don't know one, you mark 'I don't know' and continue: it stays noted to review with your accounting firm, it doesn't block you.
Receive your calendar
Your due dates for this year and next are generated, sorted by what comes first, and you add your own from the templates. If your business changes, you tell it and the calendar recalculates while respecting everything you already marked as done.
Let it alert you
Emails at 15, 5, and 1 day by default — you choose the windows —, a single grouped email even if several things are due on the same day, a Monday summary with the next 30 days and, if you want, everything synced to your Google, Apple, or Outlook Calendar.
What those who already use it say
“I've always had an accounting firm, but I never knew what was coming or when. What changed my quarter was the direct debit date: for two years I thought I had until the 20th and I'd already been hit with a surcharge for preparing it late.”

“The annual accounts drawn as a chain — prepare, approve, and file — no calendar gave me that. The year I changed advisors, nothing fell through the cracks, because the alerts no longer depended on someone remembering.”

“It alerted me about the digital certificate with a month to spare. The previous year it expired and I spent three weeks fighting for an in-person appointment without being able to do almost anything. I give it four because I'd like to be able to add my town's holidays now.”
