Major Tax Deadlines Converge on the Final Working Day of 2025
The closing hours of 2025 bring a packed schedule of tax obligations that must be settled before the year ends. With several key deadlines expiring tonight, taxpayers face a narrow window to complete payments and submissions that will prevent additional charges in 2026.
A combination of ongoing tax instalments and end of year declarations remains active only until 23:00, when AADE systems stop accepting submissions regardless of whether users are already logged in.
Income Tax and Electronic Spending Requirements
The sixth instalment of income tax is due tonight for taxpayers who opted for an eight instalment payment plan. Another immediate obligation concerns the required level of electronic payments, which must reach 30 percent of annual income by midnight to avoid additional tax in the coming year.
ENFIA Instalments Continue Toward February Completion
Property owners paying ENFIA in 12 instalments are required to settle the tenth payment for 2025. This cycle began in March and continues through February 2026.
Amended Declarations for Retroactive Income
Individuals who received retroactive income in 2024 need to file amended declarations for each tax year these earnings relate to. Any tax arising from these submissions must be paid by 31 January 2026, with an option for up to 48 instalments.
Parental Gifts and Donations for Covering Presumptions
Declarations involving parental gifts or donations used to justify lifestyle or asset acquisition presumptions must also be completed electronically through the myPROPERTY platform before the end of the year.
Tax Filings for Individuals Who Died in 2024
Heirs are required to submit tax declarations for individuals who passed away in 2024 once registry details have been updated. These filings must also be completed by tonight.
Obligations for Taxpayers Who Moved Abroad
Taxpayers who transferred their tax residency abroad for the first time during 2024 must finalise their annual tax declaration today.
Digital Services Closing at 23:00
Several AADE digital platforms remain operational only until 23:00. After that time, submissions will not be accepted even if users stay connected.
Some services will be temporarily unavailable on 1 January due to year end processing before gradually returning online from 2 January 2026.
