The deadline for businesses to review and update their KAD codes has been postponed to October 30, 2026 (instead of June 1), pursuant to a new decision by the Governor of the Independent Authority for Public Revenue (A.1113/2026).
The Athens Chamber of Small and Medium-Sized Industries notes this in a statement and adds that the postponement of the deadline facilitates the work of businesses and the community of accountants - and tax advisors in verifying the new KAD codes (2025 edition), which were assigned as part of the automatic mapping process, in accordance with the updated European classification framework for economic activities.
The relevant declarations may be submitted by October 30, 2026, without incurring a fine, provided that no declaration of a change in the NACE code for the headquarters or branch has been submitted after March 1, 2026.
