Statutory dates. AT can extend a deadline by despacho; confirm on the Portal das Finanças tax calendar. Each period links to its legal source.

How it works

The dates are computed from the rules in the law: invoice data by the 5th of the following month (DL 198/2012), VAT by the 20th of the second month after the period with payment by the 25th (CIVA arts. 41 and 27), Modelo 22 by 31 May and IES by 15 July (CIRC).

AT sometimes extends a specific deadline by despacho, and the official calendar on the Portal das Finanças always has the final word. Use this list to plan, and confirm close to each date.

Frequently asked questions

They are the statutory dates from the law. AT can extend a deadline by despacho in a given year, so always confirm with the official tax calendar on the Portal das Finanças.

It adds every deadline as an all-day event to Google Calendar, Outlook or Apple Calendar. Import it once and the dates appear next to your other appointments.

The law moves the June (monthly) and second-quarter VAT returns to 20 September, with payment by 25 September, instead of the usual second month after the period.
