AEAT deadline calculator

Estimate your Hacienda response deadline.

Enter the notification date and business-day window from the letter. The calculator starts the next day and skips weekends and Spain-wide public holidays.

Use the date the notification legally happened: delivery date, electronic opening date, or deemed notification date.

National-holiday coverage is currently limited to the published 2026 calendar. The full count must end by 31 December 2026.

Most AEAT requerimientos use 10 business days, but your letter wins.

What this tool can tell you

This calculator turns the notification date and the business-day period written in an AEAT letter into a planning date. It skips weekends and Spain-wide public holidays.

  • Use the legal notification date shown by the delivery or electronic record.
  • Enter the exact number of business days written in your letter; do not assume every notice gives ten.
  • Save the document, result, and final submission receipt together.

Public route check

Before you act on the result

The date is only the first decision. The notice itself tells you whether to pay, upload evidence, correct information, appeal, or use another response route.

  • Confirm the final step on the official portal linked from this page.
  • If the document or route is unclear, get a case-specific review before a deadline passes.
Use with caution

Planning estimate only: this calculator skips weekends and Spain-wide public holidays, but not every autonomous-community or local non-working day. Your notice and the official calendar control. If the deadline is close, confirm it with AEAT or a qualified adviser before filing.
